Online or In-Person Course? Meaningful Discussion of Learning Effectiveness and Satisfaction of Microwave Filter Design Course in Graduate Students

A research on applying blended teaching in microwave filter design in graduate students.Background: The Covid-19 epidemic has caused many universities worldwide to switch to online courses. Taiwan did not have a large-scale local infection in 2020, so the school has implemented a blended teaching plan, combining online and in-person courses.Intended Outcomes: Discuss the effectiveness and satisfaction of the Microwave Filter Design Course in Graduate Students for two classes, Online or In-person course.Application Design: This study uses a quasi-experiment to teach microwave filter courses in the two classes. The teacher integrated into the Flipped Classroom and Interactive Response System (IRS). Students must use the APP to complete the preclass preview and prepare materials. Class A (N = 14) uses in-person classrooms for the whole course; Class B uses blended teaching. The first eight weeks are synchronized online, then mid-term exams, and in-person courses are used for the next ten weeks. Students in two classes in the last week filled out the course satisfaction questionnaire.Findings: Class B achieved better results in the eighth midterm exam week, showing better learning results. Although students in both classes are highly satisfied with the course, Class A is more satisfied than Class B. For graduate students participating in the microwave filter design course, in-person classrooms and blended teaching can achieve good learning results and satisfaction. However, teachers must pay attention to students' reception and understanding of flipped classrooms when using online teaching. And timely and in-depth guidance on the accuracy of APP use.
