### Evaluation of CPLM with Brainwave Measurements  
It is a challenge to perform brainwave experiments in a classroom. EEG equipment is becoming portable and miniaturized, and with simple preparation it is possible to get accurate brainwave information [37] to improve student performance [38]. The electroencephalogram (EEG) is a widely used non-invasive method for monitoring the brain. An EEG device uses forehead electrodes to detect brain electrical waves and electronics to process signals and transmit data via Bluetooth communication to a laptop, tablet, or smart phone. It uses a signal processor and communication unit to send data to a communication channel [39]. EEG has been used in the field of educational research to evaluate and monitor the effectiveness of traditional and modern teaching methods or to develop feedback-based systems. The EEG detects human brain waves based on selected characteristics of \(\alpha\), \(\beta\), \(\delta\) and \(\theta\) waves. The variations in \(\beta\) waves in an EEG are strongly correlated with attention and \(\alpha\) waves are strongly correlated with meditation [40]. Attention is the behavioral and cognitive process of selectively focusing on a discrete aspect of information, whether viewed as subjective or objective, while ignoring other perceptual information [41]. In contrast to attention, meditation is an intentional and self-regulated focusing of attention to relax and calm the mind [42]. Meditation does not represent a physical state, but rather \begin{table}

Figure 6: Time measurement of procedure time CG and EG, LLE and HLE. a mental one, of an individual and refers to a reduction in active mental processes of the brain. That is, a higher level of relaxation indicates that an individual is more relaxed and less stressed [43]. There are different cognitive aspects that can be measured with EEG devices [37], such as reading context [35], presentation patterns [37], interactive behavior [35], outtainment [44], e-learning [45; 46], motor skill acquisition [47], and promoting performance [48]. We can measure different brain waves, such as alpha, beta, gamma, delta, and theta waves. A device was used to measure attention and meditation in various given situations. In order to check and prove the theory, we decided to use a simple EEG device, the Mindwave Mobile 2. We selected a group of 15 EG students and measured their EEG activity while watching relaxing videos, while working on a personal computer where they performed a simulation problem solving, and while using a VR system and a robot VR simulator.
