“…Students connect the available modules, prove the results against the theory, and carry out an analysis according to what has been learned, to draw conclusions and suggestions. This is in accordance with the definition of the trainer kit itself in that the trainer is one of the practical learning media that can facilitate students in proving the characteristics of a series they have learned through assembling, measuring, analyzing, and concluding activities with reference to the learning objectives [42]- [46]. As an implication, the learning outcomes increase, as been proven by [47].…”

This research develops a phase-shift RC Oscillator trainer kit that can be used to give undergraduate students an understanding of one of the materials related to analog circuit practicum. The Oscillator is one of the essential subtopics to be examined thoroughly by electrical engineering students. Furthermore, the Resistor and Capacitor modules were provided separately to be connected to the trainer through jumper cables. The phase-shift RC circuit in the trainer kit used a single Op-Amp 741 while the Network model utilized an Inverting Amplifier to determine the gain which must be ≥ 29 times, therefore, Rfeedback ≥ 29 Rgain (Rfeedback = 30 kΩ and Rgain = 1 kΩ). Two tasks in this learning media were completed by students, namely measuring the output frequency and observing the phase shift. The output signal on this trainer kit was observed using only an Oscilloscope and a frequency counter. The phase inverter of the phase-shift RC Oscillator adjusts the output signal by 180o and sends feedback to the input, therefore, there is positive feedback. Meanwhile, the trainer kit had an output frequency specification of ~649 Hz (C = 100 nF, R = 1 kΩ) and it shifts the phase by 60o on each RC network. Using 2 and 3 R-C networks, the phase shifts were 120o and 180o, respectively. The trainer kit was packaged in a box made of acrylic with dimensions l x w x h = 20 cm x 28 cm x 5 mm. Through a questionnaire consisting of 13 criteria, this trainer kit was declared valid, namely r count > 0.2960 (5%) and reliable (Cronbach's alpha > 0.60, which was 0.732) to be used as a learning media based on user responses, namely students (N = 35). In the context of technical education, this trainer kit also supports the efficient implementation of practicum without compromising the learning objectives due to the ease of operation (plug & play through jumper cables) compared to fully assembling the circuit using a project board.

This paper considers the experience of elaborating and implementing an on-site and distance practical study of electronics and circuit Engineering in the educational process. Authors provide possibilities of using both distance and on-site laboratory practical works. The paper includes recommendations for choosing hardware-based solutions. It also shows the implemented version of remote user access to individual data of laboratory research, which provides individualization of obtaining experiment data, when using FTP means of data transfer. Data from a remote experiment, in this case, is completely closed from access by third parties, while the teacher is given access to data from experimental studies of all students. The solution was implemented in the LabVIEW platform, as well as the general solution for implementing software access to a remote bench. The paper describes the main elements of the hardware and software system, shows its structure and presents the work examples. It also notes the integration of the LabVIEW software and the Multisim circuit and system simulating platform, which serves to improve the quality of specialists training during distance and on-site practical works. The authors consider several options for conducting distance and on-site laboratory practical works when preparing laboratory layouts for use. The work of students, both distance and on-site, as well as teacher-student interaction, is organized using the MOODLE platform.

“…Within introductory courses on the subject of Digital Electronics, the use of simulators to predict the behaviour of the circuits is very useful, in addition to gaining an understanding of the distribution of physical pins of the integrated circuits to make virtual and physical connections (Itagi & Tatti, 2015;Mwikirize et al, 2010;Poole, 1994). In situations such as COVID-19 emergence, the teaching and learning processes are carried out online in individual environments (Barba-Pingarrón et al, 2022;Monroy-Varela et al, 2022), so it is important to still provide students with an application context for the theoretically analysed digital circuits; with this, students verify that the knowledge acquired is useful to solve multiple problems in their physical environment.…”

En este trabajo se presenta el desarrollo de un sistema didáctico de control de riego agrícola de presición utilizando dispositivos electrónicos fundamentales que se presentan y analizan típicamente en un curso de electrónica digital. El proyecto integra la aplicación de diversas aplicaciones de los latches, contadores y decodificadores enfocados en controlar un sistema de producción agrícola. A través del sistema desarrollado se controla la cantidad de agua que se suministra a una planta, utilizando la humedad del suelo como variable de monitoreo para el sistema de riego de agua. La calibración del sistema de riego permitió identificar que cada uno de los pulsos de riego provee una cantidad de 0.25 militros de agua, con lo que se utiliza el recurso de manera eficiente a través de la implementación utilizando técnicas computacionales y dispositivos de hardware de bajo costo. El sistema puede ser modificado y adaptado a otros procesos agrícolas para regular el sumistro de soluciones nutrivas o fertilizantes líquidos.
