Development of student worksheet of mathematical modeling learning using a financial context for senior high school students

This study aimed to produce a valid and practical Student Worksheet of Mathematical Modelling Learning using a financial context for senior high school students. In addition, it aimed to find out its potential effects on students' mathematical modelling abilities. The study was conducted in the XI IPA Grade of Public Senior High School No.11 of Palembang City, 2018/2019 Academic Year involving 39 students. This was a development study consisting of a preliminary stage covering the stages of analysis, design, and development, the formative evaluation stages covering self-evaluation, prototyping (expert reviews, one-to-one, and small group), and field tests. The data collection techniques used walkthroughs, observations, and interviews. The result of this study is a valid and practical Student Worksheet Mathematical Modelling Learning using a financial context of compound interest learning material. The validity was based on context, construct and language viewed from the results of expert review and one to one, small group, and analysis of the student answers in the field test stage.
