From the beginning of this semester to the present, I have chosen to update PowerPoint as a multimedia object and update and improve it to reflect my understanding of the principles of multimedia learning. Because, through different activities every week, we have been exposed to infographics, screencasts, edited videos, podcasts, interactive games, Google Earth, etc. The powerful display and inclusiveness of PowerPoint can combine all multimedia results.

This time, the theme of my updated PowerPoint is EDCI 337: interactive and multimedia learning. Before starting, I used the three main steps of reverse design: determining the desired result, determining the evaluation evidence, and planning the learning experience and guidance. Therefore, PowerPoint should reflect the critical content that students (audiences) want to understand and use. Second, design interactive sessions to know whether students understand. Therefore, while using PowerPoint to interact, add other multimedia activities to help students understand and learn.

Cognitive theory points out that learning is the acquisition of knowledge and the development of understanding. Therefore, we can understand the learning nature of these behaviours so that education can shape individuals. Constructivist theory points out that teacher guidance is the source of student learning. The cognitive theory emphasizes reading and lectures as learning methods. It explained that it could be predicted that reading text on PowerPoint slides is not as effective as narrating images in PowerPoint.

Generally speaking, the convenient, fast and efficient multimedia teaching through PowerPoint makes the teaching method convenient and fast and improves the teaching efficiency. Powerpoint can use text, pictures, animation and video to carry out teaching activities. It is challenging to clarify the key points and difficulties of knowledge with ordinary teaching methods so that some abstract and complex knowledge becomes intuitive and vivid. Especially the use of pictures, animations, and videos is more intuitive and vivid. In addition, the amount of information is enormous. By making multimedia courseware, teachers can bring a lot of information to students, and they can also update rich and cutting-edge materials through the Internet. It makes classroom teaching activities lively and exciting, enlightening and accurate, and can fundamentally change the traditional monotonous teaching mode, thereby enlivening students’ thinking and inspiring students’ interest in learning.
