Insights into Cognitive Engagement: Comparing the Effectiveness of Game-Based and Video-Based Learning
share
The analysis of brain signals holds considerable importance in enhancing our comprehension of diverse learning techniques and cognitive mechanisms. Game-based learning is increasingly being recognized for its interactive and engaging educational approach. A pilot study of twelve participants divided into experimental and control groups was conducted to understand its effects on cognitive processes. Both groups were provided with the same contents regarding the basic structure of the graph. The participants in the experimental group engaged in a quiz-based game, while those in the control group watched a pre-recorded video. Functional Near-Infrared Spectroscopy (fNIRS) was employed to acquire cerebral signals, and a series of pre and post-tests were administered. The findings of our study indicate that the group engaged in the game activity displayed elevated levels of oxygenated hemoglobin compared to the group involved in watching videos. Conversely, the deoxygenated hemoglobin levels remained relatively consistent across both groups throughout the learning process. The aforementioned findings suggest that the use of game-based learning has a substantial influence on cognitive processes. Furthermore, it is evident that both the game and video groups exhibited higher neural activity in the Lateral Prefrontal cortex (PFC). The oxygenated hemoglobin ratio demonstrates that the game group had 2.33 times more neural processing in the Lateral PFC than the video group. This data is further supported by the knowledge gain analysis, which indicates that the game-based approach resulted in a 47.74 calculated from the difference in pre-and post-test scores.
