Ethnomathematic Worksheet by Scientific Aproachs

Abstract

The purpose of this research is to develop worksheet based Ethnomatematics with Scientific approaches to improve outcome learning mathematics in secondary school that valid, practical and efective. Development of learning models in this study using ADDIE development model, because it has a simple stage, but clear and understandable. The model consists of five main stages, namely (Analysis, Design, Development, Implementation, and Evaluation). Tests performed on the class VII B Mts Riadlul Jannah NW Penjor. Based on the analysis of the trial showed that the worksheet based Ethnomatematics with Scientific approaches to improve learning outcomes mathematics in secondary school meet the criteria for a valid, practical and effective. Criteria of validity can be seen from the analysis results that meet the criteria of validity worksheet very valid acquisition of the actual total score of 313 out of a maximum score of 375. Criteria of practicality can be seen based of results teacher's assessment analysis and the results of analyzing the response of students who meet the criteria are very practical based on the assessment of teachers with the acquisition of the actual total score of 123 out of a maximum score of 135 and has achieved practical criteria is based on the students' responses with the percentage of 88.33% of standards. Criteria for effectiveness and results from analysis ≥ 75% student achievement test which student learning outcomes have achieved an average score of 67.5 or value is above the minimum of thoroughness criteria (KKM) 65 and the percentage of classical completeness reached 83.33% of the standard 75%.
