Learning Impact of a Virtual Brain Electrical Activity Simulator Among Neurophysiology Students: Mixed-Methods...

Area of Science:

• Biomedical education
• Neurophysiology
• Medical simulation

Background:

• Virtual simulation offers a platform for skill development in computer-generated environments.
• Traditional electroencephalography (EEG) training relies on hands-on exercises, with no prior use of virtual simulations.
• There is a need for innovative methods to support student learning in neurophysiology.

Purpose of the Study:

• To evaluate the impact of a virtual EEG simulator on students' theoretical knowledge and practical skills in EEG measurement.
• To assess the simulator's utility within a biomedical laboratory science neurophysiology course.

Main Methods:

• A computer-based EEG simulator was developed, enabling virtual electrode placement and EEG graph interpretation.
• 35 participants were randomly assigned to three groups: virtual simulator with fuzzy feedback, virtual simulator with exact feedback, and a control group without simulation.
• Pre- and posttests assessed theoretical knowledge and practical skills in EEG electrode placement.

Main Results:

• Both groups using the virtual EEG simulator demonstrated significant improvements in theoretical knowledge and practical skills.
• These improvements were notable when compared to the control group that did not use the simulator.
• The Wilcoxon signed-rank test confirmed the statistical significance of the observed gains.

Conclusions:

• Utilizing a virtual simulator enhances students' proficiency in EEG electrode placement.
• The simulator, when integrated with practical training, deepens students' comprehension of EEG measurement.
• Virtual simulation presents a valuable tool for neurophysiology education.
