PENGARUH PENGGUNAAN LKM TRIGONOMETRI BERBASIS PENEMUAN TERBIMBING TERHADAP HASIL BELAJAR

The purpose of this study was to determine whether there was an effect of using Guided Discovery-based Trigonometry LKM on student learning outcomes in Trigonometry lectures even semester 2019/2020. This research is a quasi-experimental research with 8 students who teach trigonometry as a research subject. The design in this study used a one-group pretest-posttest design. The instrument used in this study was a test of learning outcomes consisting of pretest and posttest. The data analysis technique used was descriptive statistical analysis and inferential statistical analysis. The data were processed using SPSS 22. Based on the results of the descriptive analysis of student learning outcomes after the lecture using the Guided Discovery-based Trigonometry LKM was better than before using the Guided Discovery-based Trigonometry LKM. The average post-test learning outcome was 90.75 while the average learning outcome pretest of 28.75. As seen here there is an average increase of 62.00. While the results of inferential statistical analysis using the Wilcoxon Signed Rank Test obtained the value of Z count > Z table, namely -2.524 > -1.96, which means Ho is rejected and Ha is accepted. Meanwhile, based on the results of comparing the probability values, the Asymp value is obtained. Sig. (2-tailed) < the alpha value of 0.012 < 0.05 which means Ho is rejected and Ha is accepted. This means that there is a difference in the average results of students who use Guided Discovery-based Trigonometry LKM and students who do not use Guided Discovery-based Trigonometry LKM. That is, there is an effect of using Guided Discovery-based Trigonometry LKM on student learning outcomes.

The sum of the subjects who do the mathematics ability test is 30 students, the researcher chooses six students for the creative thinking test. Of the six students, three students were select to be an interview. There are five levels of TKBK (Creative Thinking Ability Level), namely fourth level (very creative), third level (creative), second level (quite creatives), first-level (less creative), and level 0 (not creatives). Based on the results of the analysis and discussion, it can be concluded that subjects with high ability have TKBK at the third level, namely creative with the acquisition of a score of four. Subjects with moderate ability have TKBK at the fourth level, namely highly creative with the acquisition of a score of thirty-six. While subjects with low ability have TKBK at the first level, namely are less creative with the acquisition of a score of thirteen.

ANALISIS KEMAMPUAN BERPIKIR KREATIF MAHASISWA KELOMPOK ATAS DALAM MENYELESAIKAN SOAL STRUKTUR ALJABAR RING MATERI IDEAL PRIMA DAN IDEAL MAKSIMAL

This study aims to describe the creative thinking ability of upper group students in solving Ring Algebra Structure questions on the prime ideal and maximum ideal material. This research uses descriptive qualitative research. The research subjects are students of Mathematics Education-2 Semester VI who have taken the Ring Algebra Structure course. The research subjects are three (3) students of Mathematics Education-2 Semester VI who have high mathematical abilities based on test results in the form of assignments on Ideal material. The instruments used in the study include: 1) Test; 2) Interview guide; and 3) Documentation. Based on the results of research and discussion, the findings resulted that the thinking ability of upper-class students had fulfilled all aspects of creative thinking, namely fluency, flexibility, and originality. The subject has been able to explain all the indicators that have been set very well and precisely. Subjects have also been able to prove prime ideals or maximum ideals or not both and can identify examples and non-examples of prime ideals and maximum ideals through high-level elaboration and analysis carried out by the subject. Subjects are also very able to describe Lattice diagrams on each question and can determine the subring of a ring. It's just that there is a uniqueness of the worksheet between MS, ZB, and HF. But overall the subject has fulfilled the creative thinking aspect. Thus, it can be concluded that the upper group students can be categorized at level 4, which is very creative.
