THE DEVELOPMENT OF INTERACTIVE MATHEMATICS MULTIMEDIA FOR LEARNING TRIGONOMETRY WITH REALISTIC MATHEMATICS EDUCATION (RME) APPROACH

The use of technology in mathematics instruction is intended to help develop a constructivist-based learning environment, a learning environment that allows students to construct their own knowledge. This research aims to describe the process and the result of the development of the interactive mathematics multimedia for learning trigonometry with Realistic Mathematics Education (RME) approach measured by aspects of validity, practicality, and effectiveness. The subjects were students of grade X. This research was developmental research that used ADDIE model development through five stages such as analysis, design, development, implementation, and evaluation. Data collecting method used in this research were in form of validation by the expert, and the field tests to obtain data practicality and effectiveness of the media. The results showed that the interactive multimedia that has been assessed by the validator get the valid criteria with a percentage of 78.5%. Student questionnaire results in the field test showed a percentage of 90%. Moreover, after using the interactive multimedia mostly students achieve excellent learning achievement, it is shown through the classical completeness of students test result that is 80.6%. Based on the results of expert evaluation and field test showed that the developed interactive multimedia has been valid, practical, and effective
