Abstract

Mathematics is one of the supporters of the development of science and technology. The low creative thinking of students is one of the causes of students' lack of interest in learning mathematics. The assumption for most students that mathematics is a very heavy and difficult subject, especially in solving Geometry Transformation problems. The purpose of this research is to improve students' creative thinking skills through the development of project-based learning models assisted by geogebra software and the effectiveness of these learning models. This development uses the ADDIE (Analysis, Design, Development, implementation and Evaluation) model. The trial was conducted in class XI TKJ SMK N 1 Penanggalan, Penanggalan District, Subulussalam City, Aceh Province. The results showed that in the first trial there were 12 students who completed with 60% and 8 students did not complete with 40% so that they could not meet the effective criteria. In the second trial there was an increase in creative thinking skills for students who completed as many as 18 students, 85.7% and students who did not complete as many as 3 students, 14.3%. So that the development carried out in the second trial showed an increase in students' creative thinking by 25.7%.

Abstract

This study discusses the development of student worksheets based on the ethno mathematics of Gordang Sambilan musical instrument on the conic section material of class XI SMA Primbana Medan. This research is a development research that aims to determine the process of the development of the student worksheets based on the ethno mathematics of Gordang Sambilan musical instrument on the conic section material of class XI SMA Primbana Medan which is valid, practical, and effective. The research and the development model used in this study is the ADDIE model with 5 stages. The stages in the ADDIE model are: 1) Analysis; 2) Design; 3) Development; 4) Implementation; 5) Evaluation. The instrument used to measure the validity of the developed student worksheet was an assessment qustionnaire by two mathematics lecturers and one mathematics teacher, to measure the practicality of the instrument student worksheets which is used a student responses qustionnaire and to measure the effectiveness of the instrument student worksheets which is used a test of student learning outcomes after using student worksheets. The averages validity result for student worksheets is 4.36, which means that the developed student worksheets fulfill the valid criteria. The practicality based on the student responses questionnaires obtained an average score of 4.07, which means that the developed student worksheets fulfill the practical criteria. The effectiveness of the developed student worksheets based on the student learning outcomes test of class XI SMA Primbana Medan, the percentage of the completeness of the student learning outcomes test is 83.333% which means it is very effective.
