Abstract

Spatial Analytical Geometry is one of the compulsory subjects in the S1 Education curriculum of the Mathematics Education Study Program. Learning Geometry Analytical Space is expected to be able to create a paradigm for students to use mathematics in everyday life. The purpose of this study was to develop teaching materials in the form of Spatial Analytical Geometry modules and to determine the quality of teaching materials in the form of modules developed based on the feasibility aspect. This research is a development research using the Research & Development method of the Borg and Gall model which has been modified by Sugiyono, namely the stages: (1) Potential and Problems, (2) Collecting Data, (3) Product Design, (4) Design Validation, (5) Design Revision, (6) Product Trial, (7) Product revision. The results of this study indicate that at the product validation stage carried out by material experts on the aspect of content feasibility, an average value of 3.3 was obtained with the criteria of "very good" and the linguistic aspect obtained an average value of 3.25 with the criteria of "good".Media experts in the graphic aspect obtained an average score of 3.3 with the criteria of "very good" and the linguistic aspect obtained an average score of 3.15 with the criteria of "good".Meanwhile, for linguists in the linguistic aspect, an average score of 3.3 was obtained with the criteria of "very good".Student responses to teaching materials in the form of modules in small group trials obtained an average score of 3.35 with the criteria "very interesting" and 3.5 large group trials "very interesting". This means that the teaching materials in the form of spatial analytic geometry modules produced in this study are suitable for use in learning.

Abstract

The purpose of this study is to balance the ineffectiveness of classroom learning in the learning process with conventional models, while students who receive it are more passive and afraid to express their opinions because they consider mathematics difficult to learn. This study uses an experimental quantitative research method. The population in this study were all students of grade VII. Sampling using the Random Sampling technique, where two classes were given different treatments. The results of this study are to determine the differences in the Realistic Mathematics Education (RME) approach to the critical thinking skills of seventh-grade students of SMPN 2 Kota Jambi. Based on the results of the Post-test, it can be seen that the critical thinking skills of students in class VIIIA (experimental) of SMP Negeri 2 Kota Jambi on the material set, the average value is 76.84 with a standard deviation of 6.96 while in class VIIID (Control) the average is 72.75 with a standard deviation of 11.64. Based on this calculation there is a difference between the experimental class and the control class, this is the influence of the Realistic Mathematics Education (RME) approach.
