Abstract

This research is a development research with the aim to develop the learning of mathematics oriented REACT and STEM to see the understanding of mathematical concepts of students. The learning tools developed are lesson plans, strudent worksheets and sudent books. The development model used is ADDIE (Analysis, Design, Development, Implementation and Evaluation). The material used in the learning device developed is the Bangun Datar material with the research subject being class VII students of SMP N 1 Takengon which consists of 28 students. The instruments used in this study were RPP validation sheets, worksheets, modules, concept understanding tests, and teacher and student response questionnaires to the developed tools. Analysis of the data used is the analysis of validity, practicality, and effectiveness. The results obtained are learning tools are included in the valid category, based on the results of validation by validators of mathematics education experts, learning model experts and learning media experts. The device is categorized as practical to use based on 1) the results of observations of the teacher's ability to carry out the learning process using the learning tools developed are classified as good, 2) the teacher's response to the device is very good, and 3) the student response is very good to the device. REACT and STEM oriented learning tools are also effectively used to see students' conceptual understanding abilities which show that the average score of students is more than the KKM set by the school, which is 83.60 > 70

Abstract

This research aims to look at differences in concept comprehension capabilities using the Problem Based Learning model assisted by Geogebra Software compared to conventional learning. This research is a asi research experiment with quantitative approach using non eguivalent group research design. The population in this study is as straight as grade XI MAN 1 Takengon class XI IPA which consists of 3 classes namely XI IPA1, XI IPA2 and XI IPA3. The selection of samples using random sampling resulted in the selection of class XI IPA1 as an experimental class of 26 students and class XI IPA 3 as a control class of 27 students. The instrument used in the form of a test of mathematical understanding ability in the form of a description test. The data analysis used an independent two-sample test, as abnormal data was used by mann-whitney tests. The results showed that differences in understanding students' mathematical concepts through the application of Problem Based Learning learning models assisted by GeoGebra media in Trigonometric materials.

Abstract

This article was written aiming to look at the application of the model Missouri Mathematics Project (MMP) in enhancing reasoning ability and the Advanced Mathematical Thinking (AMT) of students. This research is an experimental study with a quantitative approach and Randomized Pretest-Posttest Control Group Design research design. The sample in this study were students of class XI.1 who became an experimental class by giving treatment in the form of learning model  Missouri Mathematics Project (MMP) and class XI.2 students as a control class by giving treatment using conventional learning. The instruments in this study were tests in the form of pretest and posttest which were used to see the improvement of reasoning ability and the Advanced Mathematical Thinking (AMT) of students. Based on the results of the study it can be concluded that the model Missouri Mathematics Project (MMP) can improve students' reasoning abilities and the Advanced Mathematical Thinking (AMT). For reasoning ability, the average N-gain of the experimental class is 0.76 while the N-gain for the control class is 0.13, while for Advanced Mathematical Thinking (AMT) the average N-gain of the experimental class is 0.66 while the N-gain for the control class is 0.49.
