Abstract
Students that are currently enrolled in bachelor studies belong to Generation Z, making them highly comfortable with using various devices with Internet access. Their permanent connection to the virtual world leads to a shift in the way they accumulate knowledge. Classical means of study, such as reading books or lecture notes, have lost ground to online oriented methods of instruction.
The challenge for today's academia is to adapt their teaching methods to these new trends, so that the students' attention is gained and maintained throughout the entire teaching activity. In teaching electronics, the laboratory classes are the most challenging part of the subject, for students, as they get to actively work with components, devices, lab instrumentation. However, a minimum amount of theoretical explanations is necessary, before actually building and analyzing any given circuit. Using a regular whiteboard for this part would make the students focus on writing down the explanations and drawing the circuit diagrams, rather than paying attention to what is explained. Moreover, the amount of information that fits on a whiteboard is limited, making the access to previously discussed topics virtually impossible.
This case study presents the effects of using a smartboard in teaching electronics laboratories to 1st and 2nd year students, an average of 200 students a year. The study was conducted over the last two academic years (2018-2019, 2017-2018) and the results are validated against two years of using a regular whiteboard (2016-2017, 2015-2016).
Some of the qualitative effects are: active participation during the theoretical explanations; undivided attention to explanations; ability to switch through the slides; emphasizing important content and comparing practical measurements to theoretical explanations; unlimited additional information can be added, to any of the slides, at any given time; easy access to laboratory explanations, emailed as pdf to the students; student access to correct laboratory explanations written by the teacher; possibility to use laboratory explanations as additional material in preparing for the final written exam.
Measureable effects include: a shortening of the theoretical explanations part at the beginning of the lab session (from 40 minutes to 25 minutes, on average), increased time for the practical experiments, increased grades at the final practical test, from 8.90 to 9.30, on average. |
