Abstract

This research aims to know about the increasing of students’ activities and achievement at grade VIII-F of SMP Negeri 9 Mataram academic year 2016/2017 in learning mathematics on straight-line equation topics with the implementation of Discovery Learning. Discovery Learning is a model for developing active student learning by finding themselves, investigating itself. The type of this research is classroom action research which was conducted in two cycles. Every cycle consists of planning, acting, observating, and reflecting. As each cycle consisting of two meetings. Data of students’ learning activities were obtained by observation and the students’ achievement data were obtained by a test at the end of each cycle. The result showed that the score of students’ activities on the first meeting of first cycle is 10,33, it is categorized quite active. While on the second meeting in the first cycle, the students’ activities score is 11,33 categorized high activity. Meanwhile, in the first meeting of second cycle, the students’ activities score is 13,34 categorized active. While on the second meeting in second cycle, the students’ activities score is 15,34 categorized very active. Based on that result, there is an increasing of students’ activities. Based on the analysis of evaluation results of students’ achievement, the average of the evaluation cycle I and II respectively is 82,84 and 88,00 with classical completeness of each cycle is 77,42% and 87,10%. By looking at the result obtained from cycle to another cycle, there is an increasing of students’ achievement. It can be conclude that the implementation of Discovery Learning model on straight-line equation topics can improve the students’ activities and achievement at grade VIII-F SMP Negeri 9 Mataram academic year 2016/2017.

Abstract

Learning media have a contribution to the teaching and learning process, not only helping teachers deliver lessons but also providing added value in learning. One of the media that can be used as a solution as an interesting learning medium is a computer-based tutorial media of mathematics. This study aims at producing a practical computer-based tutorial media of mathematics. The subject of the study is the 30 students of IX-4 class of SMPN 1 Keruak, in which it is categorized as research and development by using the model ADDIE from Brunch. Furthermore, ADDIE is the acronym for analyze, design, development, implementation, and evaluation. The instrument used in collecting the data consists of a teacher-student practicality instrument. Based on the media, the assessment for the testing of practicality is in the category "very valid” for the teachers and students with 89% for teacher practitioners and 89 3% for student practitioners. Based on the result, it can be concluded that a computer-based tutorial media of mathematical learning that has been developed is feasible to use.

Abstract

This study aimed to describe the mathematical problem solving ability of eighth grade students of SMPN 6 Mataram in terms of visual, auditory and kinesthetic student learning styles. In this study, the writer used design of qualitative-descriptive with a quantitative approach. The instruments used are student learning style questionnaires, problem-solving ability test questions, and interview guidelines. The results of filling out the questionnaire via google form, there are 191 eighth grade students who fill out a questionnaire with details of visual, auditory, and kinesthetic learning styles sequentially are 84, 70, 37. Afterwards, with purposive sampling technique, one class is selected to work on the test questions and 2 students from each learning style to be interviewed. The results of this study are students with visual learning styles have higher problem solving abilities than students with auditory and kinesthetic learning styles at each stage of problem solving. Students with visual learning styles are very good at understanding problems, good at planning, sufficient in the stage of carrying out solutions, and less in the stage of looking back. Students with an auditory learning style are good at understanding problems, sufficient at the stage of planning and implementing solutions, but very less in the stage of looking back. Meanwhile, students with a kinesthetic learning style are very good at understanding the problem, sufficient at the stage of implementing the plan, but very less at the stage of making plans and looking back.

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.

Abstract

This is experimental research. This research aims to examine the effect of cooperative learning based on ASSURE model on mathematic learning outcomes in class XI of MAN 2 Mataram. The population is entire students in class XI MAN 2 Mataram with XI Science-5 as experiment class and XI Science-4 as control class which is decided by cluster random sampling. The experiment class was divided into learning teams based on their learning style. The hypothesis test uses a separated variance t-test. Based on the hypothesis test we got that (1) There is a difference in the average of student’s learning outcomes that cooperative learning based on ASSURE model gets a higher score than direct method learning, and (2) cooperative learning model based on ASSURE takes significant effect on learning outcome that class with this model get higher gain-score category than direct method learning.

Abstract

This study aims to describe the types of errors of students who have visual, auditory, and kinesthetic learning styles in solving story problems of opportunity material. Error analysis was carried out based on the Newman procedure. The type of research used is descriptive qualitative research. The subjects of this study were students of class IX-A SMP Negeri 7 Mataram in the academic year 2021/2022 who were selected using a purposive sampling technique, then 2 students were selected from each type of learning style. Data collection techniques used are learning style questionnaires, story test questions, and interview guidelines. Based on the research results, it is known that 18 students have a visual learning style, 10 students have an auditory learning style and 2 students have a kinesthetic learning style. The data obtained from the research are: (i) students with visual learning styles tend to make transformation and encoding errors, (ii) students with auditory learning styles tend to make comprehension, transformation, process skill, and encoding errors, and (iii) students with kinesthetic learning styles tend to make comprehension, transformation, process skill, an encoding error. Although at first glance it looks the same, there are differences in the errors of students with auditory learning styles and students with kinesthetic learning styles, where in the process skill error of students with auditory learning styles are wrong in the calculation process while students with kinesthetic learning styles do not perform calculations to completion (jammed).
