With the deepening of reform and opening up, my country’s preschool education has entered a vigorous development. At the
same time, higher requirements are put forward for the field of preschool education. Preschool education is an important part of
education, and preschool education is the foundation of basic education. However, the informatization construction in the field of
preschool education in my country has just started. In order to implement the planning requirements of the Ministry of Education
on strengthening the informatization construction of preschool education, build a digital platform, improve children’s quality,
promote the harmonious development of children’s body and mind, improve professional ethics and the professional level of
preschool education practitioners with the help of modern new media, and meet the professional development and sense of
achievement, acquisition, and satisfaction of preschool education practitioners. Taking multiple measures to ensure the diversified
needs of preschool education practitioners is the important and only means for the stable, comprehensive, and sustainable
development of preschool education. e data visualization platform of IOT architecture designed in this paper for edge
computing ensures the application of massive data in preschool education courses, ensures the stability of system data
transmission, and realizes the visualization of IOT terminal data. erefore, the introduction of data mining technology in this
paper can improve the utilization of resources, provide support for teachers, students, and ordinary users, and enhance the
versatility of the preschool education resource platform.
1. Introduction
Today, with the reform of China’s education system, pre-
school education has become more and more important [1].
Many scientific research institutions and educational in-
stitutions actively introduce information technology and
develop and build a preschool education resource platform
[2]. ese platforms can provide teachers, students, and
administrators [3]various resources, such as children’s
mental health, children’s intellectual development, chil-
dren’s creativity improvement, and other knowledge content
[4]. With the long-term operation of the platform, a large
amount of data information has been accumulated, so it is
very important to actively improve the utilization of pre-
school education resources [5].
As the foundation of basic education, the importance of
preschool education is self-evident [6]. After the opening of
the comprehensive two child policy, the number of pre-
school children has increased significantly [7]. ese factors
also make China’s preschool education face greater pressure
than before [8]. e 19th CPC National Congress proposed
that preschool education should realize the deployment of
early childhood education [9].
e opinions of the CPC Central Committee and the
State Council on deepening the reform and standardized
development of preschool education issued in 2018 clearly
pointed out that the unbalanced and insufficient devel-
opment of preschool education in China is still very
prominent, and it is still a weak link in the whole edu-
cation system [10]. One of the problems is that the
construction of teaching staff lags behind, so the coun-
termeasures of “Innovating the training mode and opti-
mizing the training curriculum system” are put forward
[11]. e quality of preschool education talent training

depends on the curriculum of preschool education major
in each school [12].
At this stage, the preschool education talents cultivated
by secondary vocational schools are still an important part of
kindergarten teachers, but their graduates’ vocational ad-
aptation level is low, and their comprehensive quality and
ability have not yet reached the postobjectives [13]. e
fundamental reason for this phenomenon is that at present,
the preschool education curriculum of secondary vocational
schools mainly adopts the traditional three-stage curriculum
model, emphasizing theory over practice and ignoring the
connection between knowledge and specific work tasks, and
it cannot effectively cultivate students’ comprehensive
quality, key capabilities, and professional ability.
Based on this situation, it is necessary to comprehen-
sively adjust the curriculum system of preschool education
in secondary vocational colleges to truly meet the require-
ments of kindergarten teachers’ professional ability [14].
From the development situation in recent years, the
development level of preschool education has been signif-
icantly improved, and the demand for preschool education
teachers is also rising [15]. It is undeniable that for modern
society, higher education has obvious characteristics of
popularization, but most kindergarten teachers are provided
by the preschool education major of secondary vocational
schools [16]. However, the phenomenon of low employment
quality that does not match the high employment rate is very
prominent [17]. Graduates generally do not have good job
adaptability, and their comprehensive professional charac-
teristics are poor, which is difficult to meet the requirements
of kindergarten teachers’ professional ability [18]
.
e low
quality of talent training reflects the problems in the cur-
riculum of preschool education in secondary vocational
schools, which cannot achieve the goal of kindergarten
vocational ability training [19]. From the current develop-
ment situation, the preschool education major in secondary
vocational schools in China is mostly divided into three
curriculum stages, paying attention to theoretical research
methods and ignoring the key impact of practical operation
[20]. In the long-term development, the relationship be-
tween knowledge and specific work tasks is bound to be
ignored, and students’ key abilities and professional abilities
cannot be effectively cultivated [21].
To sum up, with the continuous development of society,
the importance of preschool education has increased sig-
nificantly. ese factors have led to the further improvement
of the requirements for the training of preschool education
professionals. In terms of curriculum design, it basically does
not meet the requirements of the professional ability of
nurses, and it is difficult to meet the actual needs. Since the
concept of competency based vocational education was put
forward, it has gradually attracted the attention and research
of vocational education in China and has been widely used in
the curriculum reform of vocational education.
As a front-line educator of secondary vocational pre-
school education, finally, the author has a real understanding
of the current situation of the curriculum of this major and
believes that we should jump out of the current three-stage
curriculum system of secondary vocational schools and
reform the curriculum model under the guidance of colleges
and universities. Vocational education concept: this study
will actively carry out case studies on the curriculum of
preschool education in secondary vocational schools on the
basis of the necessary ability-based vocational education,
effectively analyze the current situation of the curriculum of
case schools from the perspective of ability based, and put
forward relevant suggestions. Edge learning is a data mining
and analysis algorithm, which can recommend the required
learning materials from a large number of preschool edu-
cation resources according to the needs of users. It has an
important role and significance.
2. Related Concepts and Theoretical Basis
2.1. Concept Definition. e full name of secondary voca-
tional school is “secondary vocational and technical school.”
e secondary vocational and technical school plays an
important role in China’s vocational education system and is
in the core development position. Secondary vocational and
technical middle school mainly refers to the school that
provides vocational and technical education for students in
the whole high school stage. In secondary vocational and
technical secondary schools, the academic system of general
subjects is a three-year system, that is, the academic year is
three years. e main types of secondary vocational and
technical middle schools are ordinary middle schools, vo-
cational high schools, and technical schools, which are re-
ferred to as “technical schools” in short.
Preschool education refers to the school education
specially for preschool children aged 0–6. Due to the special
situation of preschool children, the staff engaged in pre-
school education must have the corresponding professional
knowledge. For secondary vocational and technical schools,
a special “preschool education” major is set up to cultivate
comprehensive talents who are competent for preschool
education and have professional knowledge and skills of
preschool education. For students, it is undoubtedly a very
wise choice to work in nurseries and kindergartens, which is
very consistent with the purposes and objectives of sec-
ondary vocational and technical schools.
As a professional term in the field of educational science,
each researcher has different understanding and interpre-
tation of the significance of curriculum based on different
research contents and perspectives.
e education dictionary says that “the courses taught in
schools are an organic whole with due structure and
function, so it is also called fcurriculum system” or “cur-
riculum structure.” It mainly refers to that the school usually
determines the specific training objectives based on the
overall school running objectives, the nature of the school
itself, and the nature of disciplines and majors, and it defines
the form of professional learning and the vocational skills
and working skills that need to be developed. erefore, the
division of labor and cooperation between courses is rea-
sonable and determined.
e concise encyclopedia of international education has
different understandings on the curriculum. William
Hubert, an American curriculum expert, believes that
2Mobile Information Systems
“curriculum design refers to the full range and character-
istics of the curriculum arranged by schools or other in-
stitutions.” Liang pointed out in the educational theory
volume of the Encyclopedia of Chinese preschool education
that from a macro perspective, it mainly refers to the whole
learning plan. e course aims to achieve the training ob-
jectives of the school and selects educational content. e
division of labor “reflects the purpose and nature of running
a school,” mainly the selection and arrangement of learning
content.
Another domestic researcher pointed out that curricu-
lum design is an important part of curriculum design, that is,
under the guidance of certain educational values and edu-
cational development needs, talent training units will con-
sider and formulate appropriate talent training goals
according to the needs of social development, discipline
research and development, as well as the special needs of
students’ personal career development and life pursuit.
Standardize the development and setting of the curriculum
system, organize the selection and arrangement of talents,
determine teaching subjects and training objectives, and
promote the establishment and improvement of the pro-
fessional talent training system.
2.2. eoretical Basis for the Curriculum Setting of Preschool
Education in Secondary Vocational Schools. In the process of
practice, we cannot do without the guidance of scientific
theory. Only in the process of practice under the guidance of
scientific theory can we achieve good results. e curriculum
should be scientific and reasonable, with both professional
theoretical basis and relevant policy basis. e concept of
competency standard vocational education breaks the re-
strictions of China’s traditional discipline standard talent
training mode and is more conducive to improving the
quality of vocational education talent training. Based on this,
this study selects three secondary vocational schools in
Qingdao as perfect kindergartens, which is the theoretical
basis of educational curriculum. e theory of competency-
based vocational education curriculum originated in the
United States in the 1960s. It is believed that the traditional
educational concept pays too much attention to the ex-
planation of book knowledge points and ignores the culti-
vation and improvement of students’ practical ability.
erefore, it greatly affects the effect of education. e
ability-based vocational education curriculum is mainly to
improve students’ knowledge and professional skills on the
basis of clarifying the established job requirements and
vocational ability indicators, combined with students’ own
abilities and levels.
Compared with other previous educational theories, this
theory pays more attention to students’ practical ability in
addition to the study of textbook theory. It is mainly under
the basic premise of vocational ability training to ensure
that students can be competent for corresponding em-
ployment positions after learning. It is a relatively advanced
educational concept at this stage and has been widely rec-
ognized all over the world. Its basic characteristics include
first, pay attention to the analysis of postvocational ability
requirements, set corresponding professional courses and
evaluation indicators on this basic premise, and take the
vocational ability training objectives as the basic content
requirements of the post. Curriculum education and rea-
sonable training: second, pay attention to the improvement
of students’ comprehensive quality, carry out targeted
training according to different students’ comprehensive level
and learning ability, and adopt a differentiated evaluation
system to improve education efficiency; third, attach great
importance to the improvement of students’ autonomous
learning ability. Teachers are the main guides of students,
guiding students to make their own learning plans and
arrangements, answering students’ questions and doubts,
giving full play to students’ autonomy and initiative, and
being responsible for students’ personal growth and future.
e teacher’s first process here should not exceed 1000
predictions, and only the guidance and demonstration effect
can be brought into play. Fourth, teaching methods should
be more diversified and flexible, emphasizing the im-
provement and science of management mechanism.
In general, this theory plays a very important role in
talent training. We need to truly meet the job needs and
cultivate more excellent talents for the society. ey not only
have solid professional theoretical knowledge but also have
good practical ability and can adapt to society and positions
as soon as possible. erefore, in the future curriculum
system construction, we should take the vocational ability
training as the basis of all work, pay attention to the cul-
tivation of students' practical operation ability, meet the
needs of diversified and personalized education, and es-
tablish a student-oriented professional ability. e scientific
evaluation index system is used to comprehensively realize
the construction of the education system. Secondary voca-
tional preschool education is an important foundation and
source to provide a large number of kindergarten teachers to
the society and comprehensively improve the level of ed-
ucational practice. Combined with the relevant concepts of
competency-based vocational education curriculum, it can
give full play to its guiding role in professional curriculum
setting and improving students' comprehensive professional
ability.
According to the vocational standards for kindergarten
teachers (trial) issued in recent years, there are clear defi-
nitions and requirements for kindergarten teachers and
preschool education practitioners. e document points out
that kindergarten teachers should receive professional vo-
cational education and must have noble morality, love ed-
ucation, and have sufficient professional knowledge and
professional technical ability. is standard has become an
important reference for kindergarten teacher training.
In addition, the vocational standards for this trial also
put forward specific implementation suggestions: schools
should comprehensively analyze the requirements of school
employment, professional characteristics, and the current
situation of existing teachers, pay attention to improving the
level of relevant majors, ensure the rationality of curriculum,
promote employment, pay full attention to pre-employment
training and postemployment retraining and education,
realize the key significance of professional ethics for their
Mobile Information Systems 3
own development, guide them to actively participate in
various social practices, and comprehensively improve the
professional level and professional technical ability of kin-
dergarten teachers and preschool education practitioners.
3. Related Technologies
3.1. Edge Computing. Edge computing was explained at the
SIDCOM (Special Interest Group on Data Communication)
conference in the field of communication networks. Edge
computing originally originated from the media field. Its
meaning is a platform that integrates key technologies such
as data collection, network transmission, data storage, ap-
plication calculation, and application on the side close to the
data source or object, providing efficient services for ap-
plications under edge nodes. Edge computing is further
divided into generalized edge computing and narrow edge
computing. As shown in Figure 1, it presents a typical
multilayer edge computing architecture.
Edge computing in a narrow sense means that the
computing node is located on the data source, and the main
application of edge computing in the narrow sense is the
camera of video surveillance. Video surveillance cameras
often contain CPUs and GPUs. Performing calculations in the
camera equipment can realize face recognition in the mon-
itored images, which can improve the speed at which the
monitoring personnel receive alarm responses. As a result of
using such a design, the cost of the terminal equipment is very
high, the quality and volume of the terminal equipment are
doubled compared to the traditional equipment, the power
consumption is also very large, and the heat dissipation
function is poor. In the industrial Internet of ings appli-
cation environment, that is, data processing is performed on
the sensor terminal, and most application scenarios require
low-power products as terminal devices, and even some
products are powered by batteries, which have certain re-
quirements on the power consumption of terminal devices.
erefore, the edge computing described in this article refers
to the generalized edge computing.
In a broad sense, edge computing refers to being far away
from the cloud, being under the same network node as an
object or data source that is close, and performing data
processing. is kind of transmission process from the
sensor of edge computing in the narrow sense to the cloud is
called the computing node, and the calculation of the node
after the data settlement in the same network environment is
also called fog computing. At present, most of the edge
computing technology research refers to generalized edge
computing, and because the computing nodes of generalized
edge computing are not limited by the conditions of IoT
terminals, developers can configure servers with different
computing power according to their needs so as to realize
edge computing. e calculation of points can be applied in
more and more complex scenarios.
To sum up, the three data visualization graphics libraries
mentioned above will be compared in this article from the
perspectives of compatibility, underlying implementation
and open source, as shown in Table 1:
3.2. Data Mining. e extensive research and extensive
application of data mining can be regarded as the result of
the natural evolution of information technology. As a
multidisciplinary field, data mining can be defined in
many ways. Even if the term “data mining” itself is
interpreted, it cannot fully cover the rich content it
contains.
Both clustering and outlier analysis can be classified as
unsupervised learning, as shown in Table 2. Clustering
tasks analyze data objects without regard to class labels,
usually due to the absence of labeled class data in the
dataset. In general, outliers are discarded as noise or
outliers in most data mining tasks. However, in some
application scenarios such as fraud detection, outlier
analysis can be interesting. Outlier analysis, also known as
anomaly mining, is generally closely related to cluster
analysis methods.

4. Experimental Results and Analysis
4.1. Data Collection and Testing Environment. Qingdao
vocational and technical middle school is the only public
vocational and technical school in Qingdao Development
Zone, and it is also a national key vocational middle school.
Qingdao vocational and technical middle school has 89
classes, more than 5000 students, and 282 teaching staff, of
which more than 70% of the teaching staff have intermediate
and senior titles, and 117 double qualified teachers. ere are
16 teaching majors, including preschool education, ani-
mation design, accounting, logistics management, business
Korean, electromechanical technology application, com-
puter, and so on. Qingdao vocational and technical middle
school takes improving students' employability as the basic
development direction, serves students and the society, pays
attention to the cultivation of students' professional and
technical ability, the teaching of professional knowledge, and
the cultivation of professional and professional quality as the
purpose, and adheres to the school running philosophy of
“adult, talent, success.”
e preschool education major of Qingdao vocational
and technical middle school began to recruit students in
2001. Up to now, the number of graduates of the preschool
education major of the school has exceeded 2000, mainly
concentrated in kindergartens in small and medium-sized
towns such as prefectures, cities, and towns. At present,
the preschool education major of the school has 360
students and 25 full-time teachers. At the same time, the
major is also equipped with piano room, art classroom,
dance classroom, vocal music classroom, and other
training classrooms.
e hardware configuration of the edge computing
server of this system is shown in Table 3.
Chrome is currently the most widely used browser
and provides a complete page testing function. is ar-
ticle will use the Chrome browser (Developer Tools)
developer tools to analyze and test platform performance
and metrics. In the Network control panel of the de-
veloper tool, the platform can initiate the request to the
server to the whole process of receiving the returned data.
e detailed information in the Network includes the
URL path, HTTP request header, request parameters,
HTTP status code, resource file, and server response
information delay.
4.2. Analysis of the Current Situation of the Curriculum Setting
of the Preschool Education Major in the Case School.
According to the curriculum concept of this study, that is,
according to the concept of the training objectives of the
preschool education major of secondary vocational educa-
tion, plan and design the curriculum, formulate a reasonable
curriculum framework system and curriculum content
structure, and provide targeted suggestions and opinions on
class hour arrangement and curriculum arrangement
according to the different teaching conditions of each ac-
ademic year so as to create a complete preschool education
curriculum system of secondary vocational schools. rough
interviews, questionnaires, and data review, this study will
analyze the current situation of the training objectives,
curriculum structure, and discipline setting of preschool
education major in the three case schools and investigate and
understand the implementation of the curriculum.
According to the survey and statistics in Figure 3, only
8% of the students in school are satisfied with the training
objectives of their major. ese data fully show that students’
satisfaction with the training objectives is very low. At the
same time, nearly 20% of the students do not understand the
training objectives of their major, and only 2.01% of the
students think that they can achieve the training objectives
by studying professional courses, but they are very pessi-
mistic about the realization of the training objectives.
rough the results of interviews and questionnaires, it
can be seen that the students and teachers in Qingdao
secondary vocational and technical middle school generally
pay less attention to and agree with the training objectives of
preschool education. Many of them, not only students but
also some teachers do not know how to achieve the training
objectives.
It can be seen from the survey results in Table 4 that
among the three schools, only Qingdao preschool normal
school offers elective courses, accounting for only 5.19%. In
the survey of “whether it is necessary to set up elective
courses according to students’ interests,” 63.12% of stu-
dents think it is necessary, 17.51% of them think it is
necessary, and 11% of them think it is normal. Only 7.54%
thought it was unnecessary. It can be concluded that
students still generally believe that it is very necessary to set
up elective courses.
Based on the optimization of Canvas instructions, the
cache optimization method is used. After using the cache
optimization method to execute the drawing instructions,
the graphics are first saved in the off-screen Canvas, which
can optimize the original many drawing instructions into
one instruction. e optimized result can render the frame
rate up to 60 fps.
As shown in Figure 4, the unoptimized page using the
native ECharts graphics library and the page using 5 opti-
mization methods are refreshed 20 times, and finally, the
average rendering frame rate statistics are obtained. e
frame rate of rendering using the rendering optimization
method is significantly improved.
It can be seen from Table 5 that the arrangement of the
school’s professional skills classes and professional theory
classes is not the same, but in general, the class hours of
6Mobile Information Systems
professional skills classes are higher than the class hours of
professional theory classes. In the questionnaire survey of
“e Most Lack of Knowledge and Skills During the In-
ternship,” it can be seen from the survey results in Figure 4
that nearly 70% of the students believe that the basic
theoretical knowledge of teaching and the teaching
methods in the five major areas are relatively lacking, which
are all majors. 13.68% of the students think that the content
of professional skills in theoretical courses is relatively
lacking, which shows that the proportion of teaching hours
of teaching basic theories and teaching methods in the five
major areas can be appropriately increased.
At present, there are still significant differences in
quantity and quality of preschool education resources
between urban and rural areas and between regions. Taking
the student-teacher ratio as an example, since 2013, the
student-teacher ratio in various regions has been changing
in a better direction for five consecutive years, and the
difference between regions has narrowed significantly as
shown in Figure 5. However, although the difference has
narrowed, the gap between the eastern region and the
central and western regions is still relatively large. In 2017,
the student-teacher ratio of kindergartens in the eastern
region was 16.41 :1, which was at a good level, while the
student-teacher ratios of kindergartens in the central and
western regions were 21.18 :1 and 21.10 :1, respectively, and
the eastern region was significantly better than the central
and western regions; the imbalance between regions has
not been broken.

Key components of current cybersecurity methods are the Intrusion Detection Systems (IDSs), where different techniques and architectures are applied to detect intrusions. IDSs can be based either on cross-checking monitored events with a database of known intrusion experiences, known as signature-based, or on learning the normal behavior of the system and reporting whether anomalous events occur, named anomaly-based. This work is dedicated to the application of IDS to the Internet of Things (IoT) networks, where also edge computing is used to support IDS implementation. Specific attention is given to IDSs which leverage device classification at the edge. New challenges that arise when deploying an IDS in an edge scenario are identified and remedies are proposed.

To explore the application of artificial intelligence interaction technology in preschool education practice courses, preschool education, 5G wireless network, artificial intelligence interaction technology, and other relevant theories are integrated, questionnaire survey is adopted as the research method, and six-year-old kindergarten students in a city of China are taken as the research objects. Adaptive optimization suggestions are put forward from the preschool children practice curriculum learning situation, cooperation and exchange situation, learning effect, and learning attitude research. The results show that in terms of learning of practical courses, students’ cognition of learning has changed after the implementation of wisdom teaching, but the average value of some P values < 0.05 is low in the real classroom adaptation stage. In the exchange and cooperation of practical courses, it is found that wisdom teaching has the greatest influence on helping other students solve problems, with a specific P of 0.009. In terms of learning effect and learning attitude, the effect is significant after the introduction of artificial intelligence technology, with an average of 3.56 before the introduction and 4.01 after the introduction. It means that to a certain extent, preschool children can realize the role and significance of wisdom classroom teaching, which plays a certain role in teaching practice. Therefore, research on the application of artificial intelligence interaction technology in preschool education practice courses under 5G wireless network environment provides a new theoretical basis and optimization direction for preschool education in the future.

In order to improve the data retrieval accuracy of preschool education major curriculum, this paper designs an auxiliary teaching system for preschool education specialty courses based on artificial intelligence. 2000 preschool education teachers and 3000 students in M city were selected to conduct a questionnaire survey to analyze the application status of artificial intelligence technology, advantages and disadvantages of assisted teaching, obstacles and training intentions of assisted teaching, and the impact on the personal development of teachers and students. Using artificial intelligence technology to improve the shortcomings of existing preschool education professional courses, through the Vue.js technology in the artificial intelligence method to achieve the MVVM mode sharing of preschool education professional courses, using MySQL database to achieve multiuser multithread operation of preschool education system, using MySQL data to complete data storage, C# was used as the programming language to design the learning module of preschool education professional courses, and the artificial intelligence-based preschool education professional course auxiliary teaching system was designed. The experimental results show that when the retrieval quantity of curriculum resources is 600 GB, the response time of resource retrieval of the designed system is 7 s, and the retrieval accuracy of curriculum data of education major can reach 95%. The performance of the system is good.

Mobile edge computing (MEC) has been envisioned as a promising paradigm to handle the massive volume of data generated from ubiquitous mobile devices for enabling intelligent services with the help of artificial intelligence (AI). Traditionally, AI techniques often require centralized data collection and training in a single entity, e.g., an MEC server, which is now becoming a weak point due to data privacy concerns and high data communication overheads. In this context, federated learning (FL) has been proposed to provide collaborative data training solutions, by coordinating multiple mobile devices to train a shared AI model without exposing their data, which enjoys considerable privacy enhancement. To improve the security and scalability of FL implementation, blockchain as a ledger technology is attractive for realizing decentralized FL training without the need for any central server. Particularly, the integration of FL and blockchain leads to a new paradigm, called FLchain, which potentially transforms intelligent MEC networks into decentralized, secure, and privacy-enhancing systems. This article presents an overview of the fundamental concepts and explores the opportunities of FLchain in MEC networks. We identify several main topics in FLchain design, including communication cost, resource allocation, incentive mechanism, security and privacy protection. The key solutions for FLchain design are provided, and the lessons learned as well as the outlooks are also discussed. Then, we investigate the applications of FLchain in popular MEC domains, such as edge data sharing, edge content caching and edge crowdsensing. Finally, important research challenges and future directions are also highlighted.
Conference Paper
The body of the article goes on to discuss the creative models of a student’s personality’s development in the process of mastering the course «Theory and methods of musical education of the preschool children». In general, the teacher's profession accumulates a big number of opportunities for the creative improvement of a would-be teacher's personality. All types of activities used while working with children in the process of mastering the artistic competencies (like fine arts, modeling, designing, appliqué work or musical activities) require not only technical skills, but also sufficient creative imagination, lively idea, the ability to combine different tasks and achieve the goals. Achieving this task is possible if students are involved into the process of mastering the active types of musical activities – singing, musical-rhythmic and instrumental activity, development of aesthetic perception of musical works. While watching the group of students trying to master the musical activity, it is easy to notice that they are good at repeating simple vocal and music-rhythmic exercises. This is due to the young man's ability to imitate. Musical and instrumental activities require much more efforts and attention. It is focused on the types and methods of sound production by the children's musical instruments, the organization of melodic line on the rhythm, the coherence of actions in the collective music: ensemble or the highest form of performance – orchestra. Other effective forms of work include: the phrase-based study of rhythmic and melodic party, the ability to hear and keep the pause, to agree the playing with the musical accompaniment of the conductor, to feel your partner, to follow the instructions of the partiture. All the above-mentioned elements require systematic training and well selected music repertoire. Students find interesting the creative exercises in the course of music-performing activities which develop musical abilities, imagination and interpretive skills of aesthetic perception of music, the complex of improvisational creativity in vocal, musical-rhythmic and instrumental activity. The experiments in verbal coloring of a musical work are interesting too. Due to the fact that children perceive music figuratively, it is necessary for the teacher to learn to speak about music in a creative and vivid way. After all, music as well as poetry or painting, is a considerable emotional expression of feelings, moods, ideas and character. To crown it all, important aspects of the would-be teacher’s creative personality’s development include the opportunities for practical and classroom work at the university, where they can develop the musical abilities of students as well as the professional competence of the would-be specialist in music activity. The period of pedagogical practice is the best time for a student, as it is rich in possibilities and opportunities to form his or her creative personality. In this period in the process of the direct interaction with the preschool-aged children students form their consciousness; improve their methodical abilities and creative individuality in the types of artistic activity.
Conference Paper
This paper aims to highlight essential contributions in terms of management development in preschool institutions, the facts that leads to increasing quality of the entire educational process. Approaching this topic and bending with particular interest in the field of formal education in Romania, we dive into the essence of educational management so that we can offer important constructive suggestions for optimizing analysis activities and implicitly increasing performance in terms of specific management of the network of kindergartens. Preschool education is the cornerstone of the formation of human personality, as well as the first gateway to knowledge. To ensure high quality in education, a complex process is needed, very well organized and structured, which must be integrated into the institutional culture of the organization. Talking about quality management while focusing on quality in education represents in fact an analysis and careful research on management actions aimed directly at increasing the satisfaction of the needs of the beneficiaries of the educational system.

Адрес: 125993, Москва, Ленинградский проспект, 49. E-mail: zadadaev@mail.ruПредставлен обзор современных зарубежных концепций качества дошкольного образования. Оценка качества обсуждается как методологическая проблема: с точки зрения баланса значимости выбираемых параметров оценки (важных для достижения образовательных результатов дошкольников) и их измеряемости; с точки зрения баланса затраченных на процедуру ресурсов и информативности полученных данных. Анализируются результаты первого масштабного независимого исследования качества дошкольного образования в России. Специально обученные эксперты в ходе структурированного наблюдения выясняли, что происходит в дошкольных группах, как организована и функционирует образовательная среда. В исследовании использован международный инструмент ECERS-R, апробированный и опубликованный в России как «Шкалы для комплексной оценки качества образования в дошкольных образовательных организациях». Оценивались следующие параметры: предметно-пространственная среда, условия для присмотра и ухода за детьми, для развития их речи и мышления, для организации различных видов активности (занятий, свободной игры, экспериментирования, творчества), характер взаимодействия участников образовательного процесса, структура дня (распределение времени на различные виды деятельности и формы их организации), условия для партнерства с родителями в создании образовательной среды, работа с педагогическими кадрами дошкольных групп. Сбор данных в течение двух лет позволил не только обозначить достижения и дефициты вовлеченных в исследование дошкольных образовательных учреждений (n = 1357), но и проанализировать динамику качества образования в 367 дошкольных группах и сформулировать предположения о ее причинах. Результаты исследования можно использовать для совершенствования стратегии развития системы дошкольного образования, корректировки дошкольных образовательных программ, улучшения профессиональной подготовки и повышения квалификации работников системы дошкольного образования.

Relatively few studies provide rigorous estimates of the long-term effects of large-scale public preschool programs, and their findings vary greatly. This study investigates the effects in third through tenth grade of New Jersey's Abbott preschool program which has many of the features and contexts hypothesized to mitigate fadeout. The program was designed and implemented in the context of a Court mandated systemic reform of education and its funding from preschool through high school. We describe in detail the program's features including an extensive, multitiered continuous improvement system. Sample size for analyses ranged from 426 to 785 depending on the grade and assessment. Participants were primarily Black and Hispanic students living in 31 communities with high concentrations of poverty. Inverse weighting by propensity scores was employed with multiple imputation for missing data to estimate effects on achievement, grade retention, and special education. Substantial positive effects were found in language arts and literacy, mathematics, and science on statewide assessments. Effects did not fade after grade 3. Achievement effects appear to be larger for 2-year than 1-year of the preschool program. Grade retention was significantly lower through grade 10. Effects on special education placement were imprecisely estimated but consistent with other findings of reduced special education. Results were robust with respect to alternative methods to control for measured and unmeasured differences between preschool and comparison groups and for missing data. This study adds to the evidence on preschool program features and contexts associated with long-term effects.
