NodeGrade tries to provide a suitable solution for the problem of time-intensive short answer grading. This research focuses simultaneously on performance, functionality and user experience, which is underlined by a triangulated approach. The evaluation results show comparable performance of NodeGrade on public datasets, even outperforming GPT-4 on...

The assessment of affective states in online learning often relies on various devices, such as sensors, which indicate physiological reactions of a person's emotional state. It is important to note that not every university can afford the sensors and devices required for this purpose. Furthermore, not every student may be willing to monitor their e...

The aim of this paper is to describe the evaluation process and findings of an AI-based Adaptive Learning System for the Computer Science discipline at two different German universities and discuss an array of methods in regard to assessing such a system. The primary objectives have been twofold: firstly, to examine the reception of selected learni...

Mit Hilfe des AdLer-Autorentools können Lehrende virtuelle 3D Lernumgebungen konzipieren und generieren, in welchen Studierende nach den Prinzipien des Game-based Learning mit Lerninhalten interagieren können.

In this paper, we propose a classification model constructed withan algorithm based on Object-Oriented Bayesian networks (OOBN)to determine the learning style of a student. For this, the Felder-Silverman Learning Style Model (FSLSM) is used, which is basedon the Index of Learning Style (ILS) questionnaire. The idea isto use the answers to the quest...

To handle heterogeneity within students, to foster needed generic competencies, to motivate them, and to increase their employability, Pair Programming seems to be a suitable didactical method to teach and learn programming. In this context, Pair Programming was used in programming lessons and its effectiveness was evaluated. This paper presents th...

In the practical Computer Science lessons at our University of Applied Sciences the students (Bachelor of Engineering in Mechatronics as well as Electrical Engineering and Information Technology) learn the programming language ANSI-C during the curriculum. 2015 the LEGO MindStorms EV3 robots were integrated into this lessons. Looking at this teachi...

Internally differentiated instructional tasks are a strategy to handle the heterogeneity of learners’ individual knowledge levels. The use of differentiated learning tasks can make an important contribution to teaching/learning management in order to efficiently promote the individual competency development of students. This paper covers the first...

Embedded Systems are finding their way in more and more areas of our daily life. Therefore, the ability to program such systems will be more and more important for engineering topics. However, this is only one good reason why students in mechatronics Bachelor Degree Program learn a programming language at our University of Applied Sciences. This pr...

Internal differentiation is a didactic answer to the growing heterogeneity of the knowledge-base of students based on the rising permeability in higher education (e.g., different qualifications for access to university). As part of an appropriate didactic setting, learning tasks are an essential component, among many other factors. The use of diffe...

To handle heterogeneity within students, to foster needed generic competencies, to motivate them, and to increase their employability, a didactical method to teach and learn programming in non-major degree programs shall be found. Therefore, this paper covers strategies and the theoretical underpinning concerning these four challenges and gives sol...

At first glance learning obstacle seems to be a well-defined term based on the definitions of the terms learning and obstacle. To our knowledge, there is no satisfying definition and even no overview of existing ones in the field of higher software engineering education. Of course, software engineering is abstract and complex by its nature and this...

In Software Engineering education didactical foundation is still at its beginnings. In recent years, this topic is put into stronger focus, as Software Engineering becomes more and more important in our everyday life. However, it is hard to teach and learn, because of diverse factors, e.g. the immateriality of the product. Therefore it is significa...

In the context of the Bologna process the “shift from teaching to learning” is postulated to meet two central goals: To increase the students’ employability and to foster needed competencies. To be in a position to process methods and find solutions for highly complex, abstract, large, and multilayered problems, a Software Engineer has to have a lo...

Language – spoken and written – is the medium for information and knowledge sharing; and it is almost always even a role of every subject in (higher) education. The language therefore plays an important part in teaching and learning. This is further underlined by the fact that ”discipline-specific language” – which is ”the uses of language in unive...

Ziel ist es, die Qualitätsverbesserung des Lehr-/Lernprozesses in der C-Programmierung durch die Integration eines Roboters darzustellen. Dieses neue Konzept wurde bereits teilweise in der Informatikveranstaltung (Studiengang Mechatronik – erstes und zweites Semester mit 180 Minuten pro Woche) umgesetzt.

In this paper a new teaching-learning-method including the LEGO Mindstorms EV3 is presented. This computer sciences course is part of the studies of mechatronics in the first two semesters. The programming language being mediated is ANSI-C. Computer science is not the most popular subject in the interdisciplinary engineering field of mechatronics,...

The development of competencies and also the usage of E-Learning and distance education in higher education are key aspects of the Bologna Process. Through the use of E-Learning, individual learning styles (e.g., different learning conditions, speeds and pathways) and competence orientation can be supported and promoted. The combination of traditio...

Software Engineering is a very complex theme including abstract processes. Thus its university education is even more challenging; particularly in the study of mechatronics, in which various subjects are integrated and combined. In our experience the students are low in motivation concerning the subject "Software Engineering", because of the mixtur...

Due to the high complexity and numerous abstract processes in the subject Software Engineering (SWE), both, challenges in teaching and in learning arise. The teaching of Software Engineering is attempted by a new didactic approach to convey a deeper understanding of the complexity and the processes of Software Engineering in the context of the cour...

University education in Software Engineering is a challenge for both lecturers and students. Software Engineering is a very complex theme requiring various technical and nontechnical skills. At the beginning of a research project we asked which competencies our graduates need in their everyday working life. In this paper the course survey of gradua...

Software Engineering is a very complex and abstract process and therefore hard to learn and hard to teach. Especially in mechatronics software engineering is not the main focus of the university studies. Therefore students have little understanding and low motivation to spend time on it. In this paper, we share some experiences on how we tried to g...

Today's high capacity Field-programmable Gate Arrays (FPGAs) and the upcoming trend to System-On-Programmable-Chip (SOPC) require novel implementation strategies. These have to overcome long implementation times of traditional synthesis approaches. Here, a unique approach for technology mapping of both datapath modules and controller descriptions i...

In this paper, we present a new placement method which provides short implementation times for today’s high capacity FPGAs within a direct mapping environment. We show that using additional component information is beneficial for faster logic block placement. The new placement method reduces the placer’s run time by taking the module in- and output...

Rapidly growing design complexities and short time-to-market demands strengthen the need for fast and e cient functional veri cation and rapid prototyping. In this paper we present CoMGen (Con gurable Module Generator) which implements arbitrary components ranging from flattened gate-level to pre-described parameterizable module de-scriptions into...

A chip design, that uses individual technology specific macros or cells, is incompatible to alternative target technologies. This prevents most designs containing such macros or cells from being reused in a different technology, even if the logic part surrounding the macro can be easily retargeted. However, avoiding these technology specific macros...

In this paper we present a new approach to direct mapping of arbitrary combinational RTL (Register Transfer Level) components onto SRAM-based FPGAs. This method consists of a core generator which implements multiplexors and multiplexor structures directly onto FPGAs. The implementation incorporates the mapping, the decomposition and placement of th...
