Enhancing Physics Education Using Distribution of Video Lessons from Teams and Interactive Electronic Books
Shigeyasu FUJIWARA

We have developed tools to enhance the deep learning of physics, using video lessons to support preparations and review for class and interactive electronic books(ebooks) to visualize theoretical understanding, for third year students in national colleges of maritime technology.
The video lessons are composed of a summary of the key points of the class and answers to the questions. Using Teams group chat, we distributed a video lesson according to the progress of the class. To third year students, we have developed a total of 24 video lessons. They have watched about 50 videos since they were in first grade.
As a class exercise, the students solved the questions and watched the video lessons, and checked their answers.
Furthermore, the students replied to the video chat that they understood and noticed. And, the students reacted 👍 to each other's comments. Reacting to the comments of others, the students deepened their understanding from various perspectives.
The ebook contains key summaries of differential and integral calculus and mechanics and contains questions and answers from the achievement examinations.
Using the gallery function of ebooks, we teach a graphical understanding of the mechanics of a particle. For example, in graphical understandings, the slope at any point on a distance-time graph gives the speed at that point in time, and the area under a speed-time graph gives the distance travelled. Such a graphical method is very useful for deep understanding.
Moreover, using differential and integral calculus, in order to check their theoretical understanding, we gave the theoretical graph of physical quantities and formulas for gallery function of ebooks. For example, in a theoretical understanding, time integral over the equation of motion, we derive the formulas of velocity and displacement in linear motion of uniform acceleration.
Using video lessons and ebooks, students can study at their own pace any time and any place. Especially, class videos were useful in online classes when students were infected with the COVID-19 and stayed at home.
The ebook could be accessed via the homepage, , and downloaded wirelessly to an iPad or iPhone.
The educational results of this approach are discussed on the basis of student questionnaires and results of CBT (computer based testing) at the National Institute of Technology (KOSEN).
