Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran penemuan terbimbing berbantu LKPD terhadap kemampuan pemahaman konsep matematis siswa SMPN 6 Depok pada semester genap tahun ajaran 2017-2018. Penelitian ini merupakan penelitian kuantitatif menggunakan metode penelitian jenis quasi experimental dengan the nonequivalent posttest only control group. Teknik pengambilan sampel yang digunakan adalah metode cluster random sampling. Instrumen penelitian berupa soal uraian sebanyak 9 butir, dari hasil perhitungan uji validitas, uji reliabilitas, uji tingkat kesukaran dan uji daya pembeda. Uji prasayarat yang dilakukan yaitu uji normalitas dan homogenitas diperoleh hasil data yang berdistribusi normal dan homogen. Uji hipotesis menggunakan uji-t kemudian diperoleh thitung = 2,6053 > 1,6690 = ttabel mengakibatkan tolak pada taraf signifikasi 5% dengan effect size sebesar 0,5807 yang tergolong sedang. Disimpulkan bahwa terdapat pengaruh model pembelajaran penemuan terbimbing berbantu LKPD terhadap kemampuan pemahaman konsep matematis siswa SMPN 6 Depok. The Effect of LKPD Assisted Guided Discovery Model on the Ability of Understanding Mathematical Concepts of SMPN 6 Depok Students Abstract: This research aims to find out the model of LKPD assisted Guided Discovery Learning Assisted on the ability of Understanding Mathematical Concept of Students in Junior High School 6 Depok in the even semester of the academic year 2017-2018. This research is a quantitative research and uses quasi experimental type research method with the nonequivalen posttest only control group. The sample was taken by cluster random sampling. The research instrument is a description of 9 items, based on the result of calculation of validity test, reliability test, differentiating power test and difficulty level of item test. Preparation test used normality and homogeneity test is obtained that the data normal and homogenous distribution. Hypothesis test used t-test which obtained tcount = 2.6053 > 1.6690 = ttable. It means that H0 is rejected at 5% significance level and the effect size of 0.5870 (medium). Therefore, it is concluded that there is an influence of guided discovery learning model assisted LKPD on ability of understanding mathematical concept of students in Junior High School 6 Depok.

Abstract

This study aims to analyze the level of students' mathematical communication skills in solving mathematical problems in terms of cognitive style and gender in the aspects of mathematical writing, drawing, and expression. This is qualitative research with the research subjects are 37 students of VIII class. Sampling was done by purposive sampling technique. Collecting data in this study using written tests and interviews. Data analysis in this study used data collection, reduction, presentation and verification. The results showed that: 1) Students in FD and FI were both able to understand questions and gave good responses, the difference was that FI understood the problem separately while FD understood the problem as a whole; 2) FD can draw based on information on the problem without analyzing the problem but not according to problem solving steps so that there are few errors, while FI are able to draws based on analysis of the information presented correctly and in accordance with problem solving steps but there are unclear for readers; 3) FD and FI can both express results using mathematical equations and present problem solving results based on the results of visualizing the problem, but FI present results are structured while FD are not structured.
