“…Using functional near-infrared spectroscopy (fNIRS) and Socratic dialog between teacher and student, "students and teachers dance at the same pace" [13]. Now, with more advanced technology, we can see cognitive states as they occur over a period of time [94,104,108,109]. The most reliable measure of cognitive states is the electroencephalogram (EEG) [16].…”

This paper proposes a new perspective on implementing neuroeducation in the classroom. The pandemic exacerbated the mental health issues of faculty and students, creating a mental health crisis that impairs learning. It is important to get our students back in “the zone”, both cognitively and emotionally, by creating an ideal learning environment for capturing our students and keeping them—the Synergy Zone. Research that examines the classroom environment often focuses on the foreground—instructors’ organizational and instructional aspects and content. However, the emotional climate of the classroom affects student well-being. This emotional climate would ideally exhibit the brain states of engagement, attention, connection, and enjoyment by addressing the mind, brain, and heart. This ideal learning environment would be achieved by combining proposed practices derived from three areas of research: flow theory, brain synchronization, and positive emotion with heart engagement. Each of these enhances the desired brain states in a way that the whole is greater than the sum of the individual parts. I call this the Synergy Zone. A limitation of this proposed model is that implementation of some aspects may be challenging, and professional development resources might be needed. This essay presenting this perspective provides the relevant scientific research and the educational implications of implementation.

“…Due to its non-invasive nature, EEG detection is widely used in many areas such as neurophysiology, psychology, pathophysiology, cognitive neuroscience, neuroengineering, and even social psychology. Also, many studies have interpreted the relationship between specific mental states and EEG [4]. In the process of working memory, an increase in theta activity is observed, and a decline in memory working decreases the activity of the theta wave [5].…”

The brain forms EEG waves due to mental processes. This study aims to investigate the effectiveness of the EEG theta wave formed in the brain during different numerical and verbal tasks. Twenty healthy medical male students without any health problems were included in the study. The five questions were answered by the subjects via PowerPoint on the computer screen. Bipolar electrode positioning was performed. In this study, domain measurements, FFT, and power spectral density were analyzed. As a result of the study, no statistically significant difference was found between EEG theta waves obtained as a result of both numerical and verbal correct and incorrect answers (p>0.05). An increase in mean amplitude was found in both the numerical and verbal processes to respond incorrectly. As a result, no significant change was observed in the domain measurements, frequency, and power analysis of EEG theta waves during numerical and verbal correct and incorrect responses.

“…It has been reported that the level of attention is expressed in blinks and body movements [2,4]. The number of blinks of a person decreases when the attention level is high and he/she is concentrated.…”

“…In other words, we use the term of attention as a comprehensive indicator of work efficiency. In order to measure the level of attention, methods using fluctuations in respiration, heart rate, electroencephalogram, and skin potential have been studied [4,6,15]. The equipment required for these measurements is not common, and there is a physical burden from wearing the equipment, they thus are not widely available in the standard situation.…”

In this paper, we develop a real-time method for estimating the level of attention while performing a task. This method uses only a low frame rate video from a standard camera so that it can be available even on a small computer. Eye blinks and head movements are calculated from a video by using landmarks. Existing blink detection methods use standard frame rate videos, making them difficult to process on a computer with low processing performance. One obvious solution is to use videos with a reduced frame rate. We investigate the error caused by reducing the frame rate, and then to overcome the error, we further develop a new method that uses the head movements calculated from the reduced frame rate videos. Then we demonstrate the error is within acceptable ranges by using the method, and show it is effective to estimate the attention level. Since this method uses only landmark information obtained from facial images, it reduces the mental burden on the user, and also partially protects personal information. In this paper, we explain the details of the method and report the experimental results.
