More and more of today’s devices are electronic and software operated. Since they measure the signals of the real world and act as a result of processing, informatics is getting closer to interdisciplinary fields. The technology of everyday devices, automotive industry, Industry 4.0, Internet of Things (IoT) are based al-so on engineering, physics, electronics, biology and other fields besides informatics. Accordingly, the in-terdisciplinarity is important in education too, it is essential to teach related solutions of technology for the informatics teacher students since they will certainly need it during their teaching practice. Although the development of technology is still very rapid, the main principles of operation remain the same, so education should focus on this rather than on the teaching of a current software development environ-ment or hardware realization. Following this idea, we have worked out several laboratory exercises for our programme of informatics teacher students. During their work they construct some circuits, write the code and practice the fundamental methods of embedded software development. We report on how they could understand and learn the most important principles during working on an educational, a commer-cial, an industrial and a medical field related exercise. The associated experience-based learning helps sys-tematic understanding and development of creativity. Based on our experience, students are getting more self-confident by the use of modern technical systems, which we consider particularly important.

One of the classical ways of learning programming is to divide programming tasks into large groups, so-called programming theorems, and then to trace the specific tasks back to the programming theorems. Each teaching method introduces a different amount of programming theorems into the learning pro-cess, occasionally even combining them. In this article we will show that the basic and complex pro-gramming theorems have the same origin; consequently, it would be enough to present one theorem and trace everything back to it. At the end of the article, then, we will explain the practical use of still introduc-ing more theorems.

XML can be found in all areas of information technologies. However, there is no such prevalence in edu-cation. In this article, I present the result of my case study in which I checked how XML and related technologies appear in education. The research was on the Internet and it processed several Hungarian and almost the same number of foreign universities’ curriculum in English and German languages.

Today we are surrounded by IT devices and a lot of different applications from which more and more are usually work in real-time. These systems are mainly embedded systems but there are general operating systems which offers such possibilities too. Moreover, we can talk about real-time applications on the web as well. Therefore, it became very important for each informatician especially for future informatics teachers to know about the bases of this technology. Everybody knows the fact that each new technology appears sooner or later in education and finds its place in it. These new possibilities may give additional tools into teachers’ hands. The question is whether they can live with the opportunity or not.

Over the last few years, skin segmentation has been widely applied in diverse aspects of computer vision and biometric applications including face detection, face tracking, and face/hand-gesture recognition systems. Due to its importance, we observed a reawakened interest in developing skin segmentation approaches. In this paper, we offer a comparison between five major supervised learning algorithms for skin segmentation. The algorithms involved in this comparison are: Support Vector Machines (SVM), K-Nearest-Neighbors (KNN), Naive Bayes (NB), Decision Tree (DT), and Logistic Regression (LR). Various scenarios of data pre-processing are proposed including a conversion from RGB into YCbCr color space. Using YCbCr representation gave a better performance in skin/non-skin classification. Despite the settled comparison criteria, KNN was found to be the most desirable model that provides a stable performance overall the several experiments conducted.

The boundaries between science, engineering and computer sciences seem to have been blurred in the 21st century. Microcontroller programming plays a role in informatics education, while modern physics teaching integrates the potential of computer simulations and computer-controlled measurement experiments. In order to demonstrate the latter, we present an experiment to precisely identify the dynamic causes of a kinematic phenomenon solved by means of technical computer science. To investigate the role of air resistance, we developed a vacuum chamber in which the signals of sensors were detected by the NI myDAQ multifunctional device and the popular Arduino UNO. A wide range of ways are presented to control data acquisition and numerical analysis of a quadrangle signal produced by a photogate, as well as graphical representation and evaluation of derived time-dependent signals. Controlling the two devices due to their characteristics and hosting of measured data by a computer require different programming techniques from the user (LabVIEW, C/C++). The results and methods of the study can be applied in physics and computer science education at a secondary school level.
