Development of Powtoon Animation Learning Media on Flat Building Materials Class IV

Research and development is a research method used to produce certain products and test the effectiveness of these products. Research and development or what is known as Research & Development (R&D) is product oriented in the field of education. This research was conducted at SD Negeri 105330 Bangun Sari, Tanjung Morawa sub-district, Deli Serdang Regency, in class IV students. The time for carrying out this research and development is in the even semester of the 2023/2024 school year.

This research was assisted by several mathematicians as a validator/assessment. The instruments used in this study were interviews, questionnaires and documentation. Material validation was carried out with the aim of obtaining material that was in accordance with the media being developed. The results of the material validation obtained an average value of 88% in the "very valid" category. It can be concluded that the material in the PowerPoint animation media component is suitable for use without revision. Media validation is carried out with the aim of obtaining media that is suitable for use. Media validation results obtained an average value of 77% with the "valid" criterion. It can be concluded that the media is suitable for use without revision. Teacher response validation obtained an average score of 96% with the "very good" criterion so that the Powtoon animation media is suitable for use without revision. The powtoon animation media used will make the learning process in the classroom fun. Fun learning will improve student learning outcomes. Powtoon animation media will help students understand flat shape material so that students get better learning outcomes.
