Before the global outbreak of COVID-19, face-to-face instruction has always been the norm in educational institutions. But after the beginning of 2020 with the severity of COVID-19, many countries delayed the opening of schools and suspended classes. However, the number of confirmed COVID-19 cases still increased. To protect students' right to education, health and safety, students were allowed to attend classes with "online teaching" as the method of instruction. The use of QSFP28 Connectors and network technology in the Taiwan help “online teaching” more successfully.
In fact, online teaching was applied in senior high schools a few years ago. In Taiwan, for example, senior high school students usually attend cram schools after class. While teaching, cram school teachers also record course contents and make them into CDs. This way, if students are unable to attend cram schools due to school activities or health issues, they can still keep up by watching a video of the make-up class. This method is very popular and has positive results. Students who experience difficulties in the course could watch the video several times. Cram schools have tutors who can also help students with their lessons, making it less stressful and faster for them to keep up with the class.
However, when "online teaching" became a new learning routine, it wasn’t that effective. At the beginning of online instruction, teachers had to first overcome the challenge of learning and adapting to new technology. They also needed to create videos while teaching. Many teachers who have worked for decades and have been accustomed to interacting with their students to observe their reactions, expressed apprehension about using videos in class and speaking in front of a camera. Since they were not used to such operating software, they became a subject of ridicule.
For younger children, the effectiveness of online teaching was also low. In particular, kindergarten and junior high school students were unable to concentrate and only stared at their computer screen without actual participation, which greatly reduced their concentration. Parents and teachers also found it difficult to evaluate the child’s learning situation. In addition, parents who worked from home and whose children are still in kindergarten were obligated to oversee the learning situation of their children because online classes were quite demanding.
This new learning mode has more or less changed the education system, but it cannot be used on a long-term basis. During this pandemic, the use of QSFP28 Connectors and network technology as well as distance learning offered a better alternative to solving current learning conditions.
