A Case Study: Using a Neuro-Physiological Measure to Monitor Students' Interest and Learning during a Micro:Bit Activity

Interest plays a critical role in learning and development. It is able to compel students toward short term exploration, motivating them toward the pursuit of future goals, as well as leading to the development of knowledge and cognitive abilities. Interest also enables students to rise above perceived restrictions and limitations to achieve their goals. Interest therefore plays a significant role in learning and development. Currently, most of the extant research on interest has been typically done using self-report surveys or by observations, which may be somewhat subjective in nature. This study therefore aims to further deepen our understanding of the value of interest on learning, and more importantly, suggests a novel method of tracing interest development over time. An alternative measure of interest through the use of neuro-physiological markers is suggested, with examples based on two case studies out of a class of 22 students. The Empatica E4 wristband was used to collect electrodermal activity (EDA) data to capture instances of triggered interest during a 10-week curriculum, which were triangulated with behavioral observations. The study found that EDA is a possible measure for recording and tracing interest development in students, providing a more nuanced and objective measure of interest development.
