Development of Articulate Storyline Interactive Learning Media Based on Realistic Mathematical Education (RME) to Improve Critical Thinking Ability of Elementary School Students

The objectives of this study are 1) Know the process of developing interactive learning media articulate storyline based on Realistic Mathematical Education (RME) to improve critical thinking skills for students in class IV, 2) Knowing the feasibility of developing products in the form of interactive learning media articulate storyline based on Realistic Mathematics Education (RME) to improve critical thinking skills for students in class IV, 3) Analyze the practicality of interactive learning media articulate storyline based on Realistic Mathematical Education (RME) to improve critical thinking skills for students in class IV, 4) Analyze the effectiveness of interactive learning media articulate storyline based on Realistic Mathematical Education (RME) to improve critical thinking skills for students in class IV. This study uses a research and development approach (Research and Development) which consists of 10 steps. The subjects in this study are students and teachers of class IV in Purwodadi District in 4 elementary schools, namely Public Elementary School No. 1 Kuripan, Public Elementary School No. 4 Kuripan, Public Elementary School No. 4 Cengkrong, Public Elementary School No. 11 Purwodadi, Rembang Regency in the full semester of 2021/2022. Data collection techniques using interviews (interviews), questionnaires (questionnaires), and tests. The analysis used in this study is quantitative and qualitative analysis, including critical thinking ability, observation of learning, and validation of media products to articulate storylines. Product effectiveness test results in improving critical thinking skills obtained Paired Samples T-Test test results from control class data with experimental class, seen from the significance (2 tailed) showed a result <0.05 which is 0.000. Thus, it can be concluded that Ha is accepted and H0 is rejected meaning that there is a difference between the control class and the experimental class. Development of learning media articulate storyline through model Realistic Mathematic Education (RME) effective in improving students' critical thinking skills.
