Developing Mathematics Learning Kits Using the RME Approach for Students of Marine Vocational High School

Abstract

This study aims to produce a mathematics instructional kits for students of Marine Vocational High School using Realistic Mathematics Education (RME) approach and oriented to mathematics reasoning, connection, and curiosity which is valid, practical, and effective. This study was a research and development study. It developed instructional kits using Plomp development model which consisted of three main steps, that is: (1) preliminary research, (2) development or prototyping phase, and (3) assessment phase. The subjects of the study were 28 students of grade X in Marine Major class of SMK Negeri 7 Kupang. The validity of the instruments used was a validation sheet. The practicality of the instruments used was a teacher assessment sheet, students assessment sheets, and observation sheets of learning implementation. Then, the effectiveness of the instruments consisted of a test for measuring students’ reasoning and connection, meanwhile a questionnaire was to measure students’ curiosity. Data analysis was conducted by converting quantitative data of assessment scores, students’ scores of test, and questionnaire to qualitative data. This research resulted mathematics learning kits for students of Marine Vocational High School using Realistic Mathematics Education approach and oriented to mathematics reasoning, connection, and curiosity in the form of lesson plan and student worksheet which have met the criteria of validity, practicality, and effectiveness.
