Adipu, Miske Setiawati, 2023. Developing Reading Materials Using Interactive Multimedia To Improve Young Learners’ Reading Comprehension. Thesis. Postgraduate Program in English Language Education, State University of Gorontalo, Advisors: (1) Prof. Dr. Kartin Lihawa, M. Hum, (2) Dr. Sartin T. Miolo, M.Hum There are four English skills that students must achieve namely speaking, listening, reading, and writing. However, some English courses focus more on speaking skills; therefore they do not provide enough reading materials for students because they tend to emphasize students' speaking ability. The objectives of this research were: (1) to describe the target needs of young learners to increase reading comprehension using interactive multimedia (2) to describe the learning needs of young learners to increase reading comprehension using interactive multimedia, and (3) to develop appropriate interactive multimedia for young learners to increase their reading comprehension. The limitation of this research was reading materials developed can only be used by English courses or other non-formal schools that do not use formal curriculum. This research was conducted at MY LIBERTY International English School and the participants were 16 instructors and 14 young learner students aged 10-12 years old. The methodology of this research was Research and Development (R&D). The model development was adapted from ADDIE model proposed by Branch (2009) and it consisted of Analysis stage, Design stage, Development stage, Implementation stage, and Evaluation stage. There were four instruments to collect the data namely target need questionnaire, learning need questionnaire, expert judgment questionnaires and test. The data from the target needs analysis were analyzed quantitatively using frequency and percentage; its results were used as groundwork to develop the reading materials for English course. The quantitative data from the expert judgments were analyzed through descriptive statistics, with review and suggestions from the experts were used to revise the first draft. After the revision, the final product was implemented into small group trial and big group trial. The result tests from students were analyzed quantitatively using KKM standards that had been set. Based on research findings, the reading materials for students aged 10 until 12 years old that have been developed is appropriate accordingly to students’ target needs and learning needs.
