Abstract

This study aims to produce Mathematics Student Worksheets (LKPD) with a Scientific Approach for State Vocational High School (SMK) 2 Bengkulu City on the material of quadratic equations and functions that are valid, practical and effective. The type of research used is development research (Research and Development) with the Borg and Gall Sugiyono model. Based on the results of the product assessment from the material expert validator, the average result was 89.03% of the "Very Valid" criteria, and the results of the product assessment from the media expert validator, the average result was 91.70% of the "Very Valid" criteria. On the teacher's practicality questionnaire sheet, the results were 92.11% of the "Very Practical" criteria, and on the 27 students' practicality questionnaire sheet, the results were 87.58% of the "Very Practical" criteria. While the results of the student learning test obtained an N-Gain value for the experimental class obtained an average value of 0.81 "High" criteria and for the N-Gain value of the control class obtained an average value of 0.63 "Medium" criteria, the t-test value obtained was 0.000 while the level ???? = 0.05. Based on the results of the hypothesis test with the independent samples test, it was stated that the research hypothesis was accepted because the value of 0.000 <0.05. was rejected and accepted that the increase in students' mathematics learning outcomes using the Student Worksheet (LKPD) Mathematics with a Scientific Approach was better than students who learned through ordinary learning and it can be concluded that the learning media developed was effective to use.

Abstract

The purpose of this study was to determine whether realistic mathematics learning based on ethnomathematics on geometry material could improve the mathematical representation ability of seventh grade students at MTs Negeri 2 Bengkulu Utara. The benefit of this study was to motivate students in mathematics learning so that it could. improve students' representation ability. This type of research is a quantitative quasi experimental design with a research approach. Data collection techniques were carried out with essay tests (pretest and posttest) and documentation. Data collection tools were in the form of essay questions. The results of the students' mathematical representation ability test obtained an N-Gain score of 0.687 <0.7, so the distribution of N-Gain scores was included in the moderate category and the interpretation of the effectiveness of N-Gain scores of 68.70 <70, so it was included in the quite effective category. Based on the results of the Independent Sample T-Test, the results were 0.01 (sig, 2-tailed), and this value was smaller than the significance level of 0.05. So the hypothesis proposed Ho is rejected and Ha is accepted, so that the increase in students' mathematical representation abilities with the realistic mathematics method based on ethnomathematics is better than students who learn with ordinary learning, and it can be concluded that realistic mathematics learning based on ethnomathematics is effective to be applied in the learning process.
