U ovom radu opisan je razvoj, izrada i validacija didaktičkog učila za kalibraciju senzora mase pomoću računala. Didaktičko učilo sastoji se od elektroničkog sklopa za prikupljanje, obradu i slanje podataka zasnovanog na mikroupravljaču ATtiny2313, senzora mase te kućišta. Senzor mase spojen je na pojačalo signala i analogno digitalni pretvornik HX711. Digitalni signal se s pretvornika HX711 šalje na mikroupravljač ATtiny2313 koji obrađuje signal te ga USB komunikacijom šalje na računalo. Za potrebe provedbe postupka kalibracije senzora mase izrađena je aplikacija za računalo u programskom jeziku C# i .Net programskom okviru. S ciljem validacije didaktičkog učila provedena je kalibracija senzora mase pomoću etalona poznatih masa te je prikazano mjerenje proizvoljne mase., This paper describes the development, production, and validation of the didactic equipment for the calibration of mass sensors using a computer. The didactic equipment consists of an electronic circuit for data acquisition, data processing, and sending data based on the microcontroller ATtiny2313, a mass sensor, and housing. The sensor is connected to an amplifier and an analog-to-digital converter HX711. With the HX711 converter, the digital signal is sent to the ATtiny2313 microcontroller, which processes the signal and sends it to the computer via USB communication. An application for a computer in the C # and .Net programming framework was created to perform the mass sensor calibration procedure. To validate the didactic equipment, the mass sensor was calibrated using.

This article describes the use of software tools and didactic equipment of electrical machines applied to the teaching in electrical engineering, specifically in the realization of an application work consisting of the characterization of the three-phase induction motor. Several studies have explored the effectiveness of teaching activities, which encompass different learning tools in the same work, from the use of didactic materials to the use of professional computer tools. The objective is the simultaneous use of didactic equipment and the calculation methodologies through specific software of industrial applications in engineering studies. In addition, to observe whether performing application work that implementing different techniques at the same time fosters the critical spirit among students. The activities students must do in the application work proposed in the subject of rotating electrical machines is to determine all the constructive variables of an induction motor, draw it, simulate its electromagnetic behavior by finite element method with a freeware available 2D program, test the motor in the laboratory following the guidelines of the current standards and, finally, compare the results obtained from the tests and the simulation, by making a critique of the results and the calculation methodology used. The application work presented in the article has been implemented during several courses in the subject of electrical machines for electrical engineering students, with satisfactory results.

Experiments for learning about electrical energy production from insolation, i.e. Sun as renewable energy source are proposed by using multimedia equipment. 24 Photovoltaic (PV) cells are physically connected to four PV modules, on which the v-i characteristics are recorded regarding to brightness and temperature. Embedded artificial light source, temperature and irradiance sensors are used in experiments as part of the test equipment. In experiments they carried out current characteristic, the analysis sensitivity of open circuit voltage, the experiments of efficiency and the fill factor, then loads of modules with different consumables. PV v-i strings characteristics are recorded and analysed on various parallel and series PV modules connections. Sensitivity analysis regarding to the light angle and irradiance for the purpose of determining the optimal power production, considering the arrangement and PV modules interconnections is conducted.

Trabalho apresentado no 20th International Conference on Interactive Collaborative Learning, 27-29 de setembro 2017, Budapeste, Hungria Teaching industrial automation is a complex mission. The classical approach is based on lectures and laboratories assisted by teachers. Nevertheless, teaching industrial automation using the classical approach is not easy because this multidisciplinary area requires knowledge in control, energy, electronics, robotics and computer engineering, among others. In this way, this paper presents an approach to teach Industrial Automation based on a self learning strategy. Instead of using the classical approach, students must develop a research work and a didactic automation prototype. The results of this methodology indicate that students increase the interest about industrial automation and clarify important aspects of assembly, commissioning, parameterization and programming of electric and electronic devices. Additionally this methodology seems to increase self-confidence of students and give them the necessary background to face the challenge of working in the real world. N/A

The aim of this paper is to introduce the reader into the field of didactic means and their use by educators at universities with technical orientation from students´ perspective. To check the status of the two selected universities in the Slovak Republic and one university in the Czech Republic, we conducted a research, which was attended by 194 respondents and its results are presented in this paper.

Diplomsko delo predstavlja pregled učnih načrtov osnovne šole z vidika obravnave vsebin o gonilih in predloge učnih metod, ki omogočajo doseganje višjih kognitivnih, psihomotoričnih in vzgojnih ciljev. Pri pouku tehnike in tehnologije ter še prej naravoslovja in tehnike ni več dovolj, da učenec pogleda v učbenik in reši nalogo iz delovnega zvezka, ampak moramo znati učence motivirati, da s pomočjo različnih didaktičnih pripomočkov dosežejo želeni operativni cilj za določeno poglavje. S pomočjo konstrukcijskih sestavljank Fischertechnik bomo dosegli, da bodo učenci usvojili in doživeli pouk bolj realistično. This paper presents an overview of primary school's teaching plans, focusing on contents of teaching methods that enable to reach higher cognitive, educational and psycho-motorical targets or goals. It is namely not enough for the pupil to check the student's book while learning Technique and technology (earlier Science and Technology) and solve a task in the Workbook, but we need to learn how to motivate our pupils that they, with the aid of various didactic tools, achieve the set targets in a certain chapter. By using constructive puzzles FischerTechnik we managed to achieve that and the pupils learned more and the classes were more realistic.

La metodología aplicada, que ha generado gran interés en los estudiantes, favorece la formación en el campo de las relaciones interpersonales, brinda oportunidades para la comunicación oral y escrita y contribuye a una mejor comprensión de conceptos por parte del alumno. Sin embargo, el método requiere de una mayor dedicación y esfuerzo de los docentes. This paper presents an experience about groupal practical works with active participation of students in chemical engineering courses. The activities being described aim to the design, construction and testing of didactic equipment to measure transport properties such as momentum, energy and mass transfer coefficients. This practical work, going beyond the learning of certain concepts, intends that students acquire capacities, skills and attitudes not considered in traditional teaching methods. The applied methodology, which has generated great interest among students, favors the training in the field of interpersonal relationships, offers opportunities for oral and written communication and contributes to better students understanding. However. the method requires more dedication and effort by instructors.
