Abstract

This study aims to produce student activity sheets for system of linear equation two variables based on problem solving that valid and practical also look at potential effects on student’s problem-solving abilities. The research method used is the Tessmer model development research, which stages consist of self review, expert review, one to one, small group and field test. The data collection techniques used in this research are questionnaire, test and interview. The questionnaire and test research data were analyzed by quantitative descriptive method, while interview research data were analyzed by qualitative descriptive method. The validity of the student activity sheets can be seen from three aspects, namely content, construct and language carried out at the expert review stage as well as comments and suggestions from the results of the one-to-one trial. The practicality of student activity sheets can be seen from the calculation results of the practicality questionnaire given at the small group stage. Based on expert review validation, one to one trial results and the results of the questionnaire calculation, the developed of student activity sheets has a validity percentage of 84.9% and has a practicality percentage of 89% with very practical criteria so that a valid and practical student activity sheet is obtained. The developed of student activity sheets also has a potential effect on problem solving seen from the overall test results that students can complete the given test questions with the description of 4 students categorized as very good with a percentage of 22.2%, 7 students categorized as good with a percentage 38.89%, 4 students categorized as enough with a percentage 22.2% and 3 students categorized as less with a percentage 16.67%.
