Abstract

This study aims to determine the order of the use of online learning platforms, the opinion of mathematical subjects teachers on the implementation of online learning, the obstacles encountered by mathematical subject teachers in using online learning platforms and the mathematics learning outcomes of students during online learning. The research method used is a mixed method. The subjects in this study were mathematics subject teachers, principal, vice principal in the curriculum field and students in class XI MIA 2 and XI MIA 4. The data collection techniques used were questionnaires, interviews and tests. The results showed that the easiest online learning platform to use to teach mathematics, monitor student activities and the most wasteful use of internet quota was the Zoom platform. The online learning platform that is easiest to use for evaluating mathematics subjects and the easiest to use for checking student learning outcomes is the Google Classroom platform. Mathematics subject teachers disagreed with the implementation of online learning. The obstacles encountered were difficulties in preparing, controlling and supervising students, making attractive learning models and media, using online learning platforms, teaching some materials, distinguishing students who took cooperation or independent work exams and learning facilities. students and internet networks. Meanwhile, the mathematics learning outcomes of students during online learning were not yet complete.

Abstract

When visiting several tourist attractions at once with limited time and an irregular schedule, of course, visitors choose the closest route to be able to visit all the places to be visited at once. This study uses an algorithm, namely the Kruskal algorithm, which aims to find the closest route to visit the five tourist attractions at once in Central Lombok Regency. The tourist attractions in question are Tanjung Aan Beach, Kuta Mandalika Beach, Sukarara Village, Sade Hamlet, Benang Kelambu Waterfall. This type of research is applied research which is generally a type of descriptive research that encourages further research. This study applies a modified Kruskal algorithm so as to produce 4 alternative closest routes with different starting points to be able to visit the five tourist attractions at once in Central Lombok Regency, namely 1) If the journey starts from Tanjung Aan Beach or Benang Kelambu Waterfall, the closest route is 60,1 km; 2) If the journey starts from Kuta Mandalika Beach, the closest route is 73.6 km; 3) If the journey starts from Sade Hamlet, the closest route is 73.6 km; 4) If the journey starts from Sukarara Village, the closest route is 82.9 km

Abstract

This study aims to describe students' mathematical investigation abilities on number pattern material in terms of gender differences. This type of research is descriptive qualitative and quantitative with the instruments used in the form of mathematical investigation test questions, and interview guidelines. Subject selection using purposive sampling, which is based on the teacher's considerations. The subjects in this study were students of class IX-A of SMPN 1 Mataram for the academic year 2021/2022, totaling 32 students. The test results were analyzed for each item based on the ability of mathematical investigation including specializing, conjecturing, generalizing and justifying. The results showed that the mathematical investigation ability of female students as many as 10 students (62.5%) were able to work on the four stages, the three-stage category was 2 students (12.5%), the two-stage category was 3 students (18.75%), and one-stage category as many as 1 student (6.25%). While the mathematical investigation ability of male students as many as 8 students (50%) were able to work on all four stages, the three-stage category was 3 students (18.75%), the two-stage category was 5 students (31.25%). In this study, interviews were conducted with 6 students from each representative of each criterion of the mathematical investigation ability test results, namely 3 male students and 3 female students. The difference between male and female students lies in the generalizing and justifying stage where female students complete neatly, thoroughly and test the general pattern for the special case they are working on while the male students complete in a short way.

Abstract

This study aims to determine the ability to solve social arithmetic problems in terms of impulsive and reflective cognitive styles. This type of research is descriptive qualitative. The research subjects were class VIII MTs Al-Khairiah NW Rajek in the 2020/2021 school year. Data collection techniques using tests and interviews. The test in question is a cognitive style test using the Matching Familiar Figure Test (MFFT), and a problem-solving ability test. Data analysis techniques are data reduction, data presentation, and drawing conclusions. The results of this study indicate that students' mathematical problem solving abilities with impulsive cognitive style require less time to answer questions. Impulsive cognitive style students at the stage of understanding the problem, many students do not understand the questions well, at the stage of making plans, implementing plans, and at the stage of looking back students have not been able to solve problems well, students are still careless in determining formulas, not careful in counting, rushing rush in solving questions, do not re-check the answers. The mathematical problem solving ability of students with reflective cognitive style takes a long time to answer questions. Students with reflective cognitive style at the stage of understanding the problem, making plans have been able to solve the problem well, at the stage of implementing the plan some students are still wrong in counting, while at the stage of looking back reflective students do not check back on the answer sheet.

Abstract

This study aims to determine the effectiveness of the articulation type cooperative learning model on the mathematics learning outcomes of eighth grade junior high school students. The research design used was a quasi-experimental design with a post-test only control group design, namely the experimental subjects in the control class and the experimental class were not chosen randomly and the experimental class was given treatment using an articulation type cooperative learning model while the control class was not given any treatment. The population in this study were all eighth grade students of SMP Negeri 19 Mataram in the 2018/2019 academic year. The number of students in this population is 188 students spread over 6 classes. The sample was selected using purposive sampling technique and selected class VIII-A as the experimental class and VIII-B as the control class. The instruments used to obtain the data are student activity observation sheets and test questions used to obtain learning outcomes data. Statistical analysis of the data was carried out using the t-test at an error rate of 5%. The data obtained showed that the experimental class learning outcomes increased by 20.67% (from 54.2 to 74.87) while the control class learning outcomes increased by 16.34% (from 51.47 to 67.81). Statistical analysis of student learning outcomes obtained is 2.01 > 1.99. The results of the statistical analysis are supported by an increase in student activity at each meeting, namely in each meeting the students in the experimental class apply the articulation type cooperative learning model so that students are actively involved during the learning process.
