Abstract

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.

Abstract

The research describes the students' creative thinking ability in solving open-ended questions based on mathematics ability. Indicators of the ability to think creatively used in this study are fluency, flexibility, and novelty. This research is qualitative descriptive research. The subjects in this study were eighth-grade students of Baitul Fattah Junior High School, Sambikerep, Surabaya, 2019/2020 school year. The instruments used were the mathematics ability test, creative thinking ability test, and interview. 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.

Abstract

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.

Abstract

The objectives of this research are 1). to find out a brief history of the Keda Nua Pu'u Nida traditional house; 2). To explore the ethnomathematical concepts contained in the Nua Pu'u Nida Traditional House. This type of research is exploratory research using an ethnographic approach with taxonomic analysis. The subjects in this study were four people and the researchers themselves. The instruments used are observation sheets, interview guidelines, and documentation. Data analysis used is a triangulation of data sources from researchers, namely by means of documentation and observation and is strengthened by reference books. The results of this study indicate the existence of geometric shapes in the traditional house of Keda Nida. The geometric shapes found are: 1) trapezoidal roof; 2) beam-shaped bearings; 3) a line-shaped roof pole; 4) the roof to the side is triangular in shape; 5) the meeting between two logs that form a corner. The shape of the parts of the traditional house can change the paradigm of students and the community under mathematics which is closely related to daily activities with culture.

Abstract

This study aims to improve critical thinking skills and student learning outcomes of geometry material by applying problem-based learning. This research is a type of classroom action research with the John Elliot model with four stages, namely planning, implementation, observation and reflection, which is carried out in two cycles. The data obtained were obtained from instruments in the form of an assessment rubric for critical thinking skills and tests to determine student learning outcomes on geometry material. The subjects in this study were class VII students of SMP Rewarangga Ende, totalling 20 people. Technical analysis of the data using a comparative descriptive technique between cycles. The results showed that: (1) there was an increase in students' critical thinking skills from the initial conditions, cycle 1, and cycle 2. In the initial condition the level of critical thinking skills in the critical category was only 43%, in cycle 1 76%, and in cycle 2 increased to 97%; (2) student learning outcomes of geometry material also increased. In the initial condition, only 42% of students experienced completeness, in cycle 1 it increased to 51% of students who completed, and in cycle 2 it increased to 68%.
