<b>ANALYSIS OF THE NEED FOR INTERACTIVE TEACHING MATERIALS BASED ON LOCAL WISDOM ON THE USE OF CAPITAL LETTERS FOR WRITING SHORT SENTENCES IN ELEMENTARY SCHOOL </b>

The proper use of capital letters in writing short sentences is a basic skill that elementary school students need to master as a foundation for good writing skills. Observations and interviews at SDN 1 Mayong Kidul showed that second-grade students still often have difficulty applying the rules for capital letters at the beginning of sentences, personal names, and place names. This condition is influenced by the teaching materials used, which are still general in nature, lack interactivity, and do not utilize local contexts that are familiar to students' lives. Based on these issues, this study aims to determine the needs of teachers and students for interactive teaching materials based on local wisdom on the subject of capital letters, analyze the effectiveness of available teaching materials, and relate these needs to students' ability to write short sentences correctly. The research used the ADDIE Research and Development (R&D) model, which at this stage focused on needs analysis through interviews and questionnaires with teachers and 27 second-grade students, then analyzed descriptively, qualitatively, and quantitatively. The results showed that 81.48% of students considered the exercises in the textbook to be insufficiently helpful, 70.37% felt that the examples provided were unclear, and 92.59% wanted to learn using local place names and figures; while teachers considered interactive teaching materials necessary to make students more interested, less forgetful, and able to correct their mistakes independently. Thus, it can be concluded that there is a real need for the development of interactive teaching materials based on local wisdom as the basis for the design and development of products to improve students' ability to use capital letters more effectively, meaningfully, and contextually.
