The proposed virtual laboratory system for digital logic circuits is composed of two main sessions, which are concept-learning session and virtual experiment session by virtual digital kit. During concept-learning session the learners can easily understand the important principles in the digital circuits to be performed. In addition, during virtual laboratory session the virtual experiments are performed by assembling and connecting the circuits on the virtual bread board, applying input voltages, making the output measurements, and comparing and transmitting the virtual experimental data. Every activity done during the virtual laboratory session is recorded on database and will be provided with the learners as a preliminary report form including personal information. Thus, the educators may check out the submitted preliminary report to estimate how well the learners understand the circuit operations. Finally, in order to show the validity of our virtual laboratory system we investigated and analysed the damage rate of real experimental equipment during class and assessed student performance on the five quizzes for one semester.

Since COVID-19, the education industry has shifted many of its activities to non-face-to-face channels, and many programs are still being conducted in non-face-to-face channels during the endemic. This study aims to analyze the quality factors affecting user satisfaction of synchronous and asynchronous channels operated non-face-to-face and compare the differences between the two channels. For this purpose, we analyzed the reviews of graduate students of the same content in the synchronous and asynchronous channels at H University in Seoul, Korea. The non-face-to-face learning quality factors derived through topic modeling are educational system quality, content quality, instructor quality, and expectation confirmation, and their effects on user satisfaction were empirically analyzed through survey responses related to these quality factors. The results showed that all of the quality factors had a significant positive effect on satisfaction, and there were significant differences in satisfaction factors between the two channels. This study is significant in that it suggests that improving the content itself for synchronous channels and improving the convenience of the program operation system for asynchronous channels is effective in improving user satisfaction.
