  • High order experimental skills’ gap identification – the need to reshape electronics teaching
    Publication . Felgueiras, Carlos; Fidalgo, André; Viegas, Clara; Alves, Gustavo R.; Petry, Clovis Antonio
    Each knowledge area has its own evolutionary way, splitting in new knowledge areas, or simply abandoning some subjects to make room for new ones. As a result we can perceive the tendency for a given subject being treated differently, according to the course where it is taught. Thus, teaching electronics is different in an Electronics Course than in an Electric Power Systems Course. In the first this subject assumes some deepness while in the second it is, at best, only superficially presented. This strategy presents some advantages for the student, like cost and time requirements, and mainly the ability to move quickly into the labor market. Nevertheless we can identify some crucial drawbacks in this approach, mainly the very weak skill level attained in some crucial subjects, usually in the boundary between established knowledge areas. So, instead of getting solid skills about crucial electric and electronic components, students are often presented with simpler interface models, i.e. electronic "black boxes". Later on, when faced with a specific type of problems, graduated student are hardly able to identify solutions, due to their inherent lack of interdisciplinary skills. This work presents some perceptions related with the lack of some electronic concepts in engineering students, necessary to understand the implications on the electric power grid resulting from the use of non-linear loads. A methodology to characterize this situation and alternatives to overcome it are also presented.

  • Learning Objects for Demanding Themes in Eletronics Teaching
    Publication . Petry, Clovis Antonio; Pacheco, Fernando S.; Alves, Gustavo R.; Felgueiras, Carlos
    This work reports the application of learning objects (LOs) for Electronics teaching, specially for themes that students struggle to grasp understanding. Two themes for Electrical and Electronics Engineering are illustrated here: equipment insulation and grounding, and the relationship between nonlinear loads and harmonic distortion. Using different learning objects, students were requested to answer some questions in a survey. Initial results presented in this work indicate that learning objects can help students to understand demanding technical themes.

  • “Sou caloiro de engenharia!”: estudo multicaso em engenharia eléctrica/eletrónica/electrotécnica
    Publication . Leão, Celina P.; Soares, Filomena; Guedes, Anabela; Esteves, M. Teresa Sena; Alves, Gustavo R.; Pereira, Isabel M. Brás; Hausmann, Romeu; Petry, Clovis Antonio
    O presente estudo multicaso tem como objetivo analisar o grau de satisfação e as percepções dos alunos do primeiro ano de Engenharia Eléctrica/Eletrónica/Electrotécnica de quatro instituições de ensino superior: duas de Portugal (Instituto Superior de Engenharia do Porto, ISEP, e Universidade do Minho, UM) e duas do Brasil (Instituto Federal de Santa Catarina, IFSC, e Universidade Regional de Blumenau, FURB). Com os dados recolhidos, após a aplicação de um questionário (319 respondentes), previamente validado, pretende-se procurar semelhanças e diferenças em relação à organização do curso e respectivo funcionamento, ao interesse dos alunos no curso, à percepção dos alunos quanto ao envolvimento dos professores, interação pessoal e satisfação geral. Os resultados da avaliação dos alunos são positivos e a maioria das avaliações está entre 3 e 4 (3-posição neutra e 4-concordo). Dos 43 items analisados, cinco apresentam comportamentos semelhantes nas quatro instituições de ensino superior.

  • Streamlining Power Electronics Teaching
    Publication . Petry, Clovis Antonio; Moia, Joabel; Pacheco, Fernando Santana; Alves, Gustavo R.; Felgueiras, Carlos
    This work intends to introduce the use of remote laboratories for power electronics teaching, by means of VISIR (Virtual Instrument System in Reality). The system is applied for the analysis of two simple circuits, a RC filter and an AC measuring network. The proposed methodology introduces remote activities after theoretical lessons, pen and pencil exercises, circuit simulations, and on-site laboratory experimentation. This strategy has been validated by professors and a pilot group of students at the Electronics Department of the Federal Institute of Santa Catarina. As a general conclusion, remote labs contribute to learning, but cannot substitute completely on-site laboratories.
