The Clever Ant: Using Video-based Learning Media to Explain Diagonal Cuboid

Considering that elementary students still enjoy playing and watching videos, researchers made a learning video to motivate elementary students and achieve active learning. There are a lot of videos that has connection to mathematics and teachers can make learning video to help elementary students understand mathematics concepts. This research focus on developing learning media in the form of video. The subject of this research is polyhedron. Researchers name this video as "the clever ant" video. A unique and interesting learning video can increase the students' curiosity. This research uses the research and development method based on the 4D model. The validation process used questionnaires given to the validators. The validator are experts from China and Indonesia. The result shows that the clever and video passed the validation process with an average score of 88%. A learning video is easy to replay which means that students can replay the video when needed. elementary Students enjoyed watching the learning video and were seriously concentrating. Based on the interview done to the students, elementary students did not feel that mathematics is a scary subject. This research proves that developing a learning video can be used to learn various subjects in various level of education.
