Various measurement and evaluation studies at the national and international levels are conducted by countries to reveal the extent of success in different education levels. One such study is the Programme for International Student Assessment (PISA) survey. The PISA survey results provide educators and decision-makers with practical and relevant in...
ÖZET
Üniversitelerin ya da bünyelerindeki programların mevcut durumunu ve dolayısıyla başarısını konu edinen çalışmalar literatürde bulunmaktadır. Üniversitelerin programlarının başarısını ölçmeye veya değerlendirmeye yönelik farklı yaklaşım ve yöntemler kullanmak olasıdır. Bu konuda temel problem programların başarı düzeyinin nesnel yaklaşım ve yö...
There are several characteristics arising from the role that education and training activities impose on teachers. That teachers have different characteristics stems from the fact that the teaching role has a multi-dimensional behavior pattern. Therefore, teacher characteristics are being researched in various fields of science and various subjects...
Personnel selection is a critical process for organizations and both quantitative and qualitative factors are used in the decision phase. The criteria should be unique to the organization and the best alternative should be chosen to satisfy requirements. This paper researches the instructor selection process for military academics. The criteria are...
This study was conducted with the aim to analyze some of the problems related to measurement and evaluation encountered in student performance task assessment. Multiple criteria decision-making methods were utilized in this study. The criteria adopted in the assessment of performance tasks and the weights of learning domains were calculated through...
In secondary education, the main aim of chemistry course is education the essential principle and concepts of scientific thought based chemistry. Thus, students acquire the understanding the knowledge and skills the concept and problems that related the chemistry field. In this study effectiveness of chemistry education was analysed according to th...
This study attempted to predict physics, chemistry, and biology and math course achievements of vocational high school students according to the variables of student self-efficacy, academic self-efficacy, state anxiety and trait anxiety. Study data were collected using a questionnaire administered to the students of a vocational high school located...
This study tried to examine performance of a chemistry teacher within the context of the special area competencies of chemistry teachers. The method proposed to evaluate the performance of the chemistry teacher consists of three steps. In the first step, the special area competencies of the chemistry teacher were converted into the model estimated...
Determining the education system's performance is important information that should be aware of by the education directors, decision makers and the planners. In this research, from the idea that claims the nature of the education activity has a multi-criteria structure; an algorithm to evaluate the performance of an education system is proposed. Th...
This study examined the relationship of emotional intelligence to academic achievement in physics, chemistry, biology and mathematics. The study consisted of students at a vocational high school. The Bar-On emotional intelligence scale was used; it comprises five dimensions and fifteen sub-dimensions. It was found that emotional intelligence did no...
The present research examines chemistry course achievement in relation to the academic self-concept, attitudes towards the chemistry course and logical thinking skills. The study sample consisted of 252 students in a vocational high school in Ankara who voluntarily participated with convenience sampling method. In the research, the academic self-co...
In this study, the relative importance of the topics of the chemistry course for the 9th grade of the secondary education and their teaching methods for an effective chemistry course have been determined by the Analytic Hierarchy Process (AHP) technique. The AHP model of the research have been composed based on the topics in the chemistry course fo...
This study determines the performance level of acquisitions anticipated for 9th grade chemistry lesson within the secondary education curriculum. In the first stage of this study, educational and training acquisitions of the curriculum were analyzed and grouped. In the second stage, the Analytic Hierarchy Process (AHP) model, which presents the pat...
In this study, an attempt was made to develop a method of measurement and evaluation aimed at overcoming the difficulties encountered in the determination of the effectiveness of chemistry education based on the goals of chemistry education. An Analytic Hierarchy Process (AHP), which is a multi-criteria decision technique, is used in the present st...

Eğitim ve öğretim kazanımları eğitim sürecinin bütünü içinde gelişebilecek kazanımlar niteliğindedir. Eğitim sürecinde edinilebilen bu kazanımların sınıf ortamında gerçekleşen kimya dersi etkinlikleriyle doğrudan bir ilişkisinin beklenmesi çoğu kez olası değildir. Bu tür kazanımları kimya içerik kazanımları etkileyebileceği gibi, kimya dersi dışınd...
Trace amounts of germanium (IV) can be determined using adsorptive stripping voltammetry in the presence of N-(2- hydroxyphenyl) - 3, 4- dihydroxybenzaldimine. The reduction current of the germanium (IV) - N-(2- hydroxyphenyl) - 3, 4- dihydroxybenzaldimine complex was measured by square-wave adsorptive stripping voltammetry. The peak potential was...
In this work, a new method for the determination of germanium in the presence N-(4-hydroxyphenyl)-3,4-dihydroxybenzaldimine was developed by using adsorptive stripping voltammetry. Various parameters such as Schiff base, supporting electrolyte concentrations, accumulation potential and deposition time were optimized.
Bu çalışmada vişne suyunda atomic absorpsiyon spektroskopisi (AAS) ile ağır metal tayinleri yapılarak, Pb, Cu, Zn, Fe ve Sn elementlerinin derişimleri belirlenmiştir. Vişne suyundaki element derişimlerinin Türk standartlarında verilen değerlerin altında olduğu bulunmuştur.
A method is described for the simultaneous ICP-MS determination of 15 toxic elements (V, Cr, Mn, Co, Ni, Zn, As, Se, Mo, Pd, Cd, Sn, Hg, Tl, and Pb) at trace levels in various foods. External calibration with Rh and Re as the internal standards was used. Reference materials were analyzed and the results compared with the reference values for the ma...
