Tracking Students’ Mental Engagement Using EEG Signals during an Interaction with a Virtual Learning Environment

Resim
Abstract Monitoring students’ level of engagement during learning activities is an important challenge in the development of tutoring interventions. In this paper, we explore the feasibility of using electroencephalographic signals (EEG) as a tool to monitor the mental engagement index of novice medicine students during a reasoning process. More precisely, the objectives were first, to track students’ mental engagement evolution in order to investigate whether there were particular sections within the learning environment that aroused the highest engagement level among the students, and, if so, did these sections have an impact on learners’ performance. Experimental analyses showed the same trends in the different resolution phases as well as across the different regions of the environments. However, we noticed a higher engagement index during the treatment identification phase since it aroused more mental effort. Moreover statistically significant effects were found between mental e...

Planning, Conducting, and Evaluating Quantitative and Qualitative Research

-
An experimental design is the traditional approach to conducting quantitative research. This chapter defi nes experimental research, identifi es when you use it, assesses the key characteristics of it, and advances the steps in conducting and evaluating this design. By the end of this chapter, you should be able to: ◆ Defi ne experimental research, and describe when to use it, and how it developed. ◆ Identify the key characteristics of experiments. ◆ State the types of experimental designs. ◆ Recognize potential ethical issues in experimental research. ◆ Describe the steps in conducting an experiment. ◆ Evaluate the quality of an experimental study.   Maria decides to conduct an experiment. She studies the question, “Do students who receive in-class instruction about the dangers of weapons in high school have different attitudes toward weapons than do students who do not receive instruction about the dangers?” Using two health classes to participate in her experiment, ...
