Abstract

This research discusses several problems found in the field, studying the learning process that is still dominated by the teacher, avoiding student participation in active learning activities, increasing student motivation in learning, and increasing collaboration between students. This research was conducted in one of the State Junior High Schools located in Makassar City, Indonesia in the academic year 2017/2018 which aims to improve student learning outcomes through the application of investigative group learning models. The research subjects were students of class VIII with 31 students. This class action research consists of 2 cycles, where each cycle consists of 3 meetings and 1 cycle test. Information related to student activities is collected using observation sheets and information related to student abilities is collected using tests given at the end of the cycle. Obtaining a score for cycle 1 is 70.48 with a completeness level of 70.79% and a score for cycle 2 is 76.32 with a completeness level of 87.1%. After applying learning with the investigation stage the group showed an increase in activity and the ability of students in the second cycle that was supported had reached classical completeness by 75%

Abstract

This research is motivated by student mathematics learning outcomes on the material two-dimentional figure still low. The learning process is still teacher-centered and there is a lack of good cooperation between students in discussions when the learning process takes place. This research is an experimental study that aims to determine whether there are differences in student learning outcomes taught by cooperative models Think Pair share and learning models The conventional research design used is Nonrandomized Control Group Posttest Design. The population in this study were all eighth grade students of Ambon-Wathan High School with 100 students and the sample in this study was 40 students, selected using purposive sampling. The instrument used in this study was in the form of test questions which consisted of question details for the final test. The analysis used is statistical analysis, which is t-test. Calculation results obtained, namely the value of Sig. (2-tailed) < α or 0.026 <0.05 which causes H0 to be rejected and H1 to be accepted. Based on the accepted hypothesis, the results of the study showed that there were differences in the learning outcomes of the experimental class and control class students who were taught with the Cooperative learning model of the Think Pair share type and the conventional learning model on the Material of Blocks and Beams

Abstract

The purpose of this research is to improve the ability of mathematical representation of Grade VIII2 students at SMP Negeri 3 Raha 2018/2019 Academic Year during mathematics learning activities with the application of cooperative learning model in the type group investigation with open ended problem approach. The type of research is classroom researh of two cycles based on teaching syllabus of the mathematics teacher in class VIII2. Each cycle is carried ot based on the competency standards to be achieved in learning. The cycle in this class action research through four stages, namely : planning of action; implementation of action; observation and evaluation; reflection. Based on the result of research conducted on the Grade VIII2 students at SMP Negeri 3 Raha 2018/2019 Academic Year on the competency standards: calculating area and volume of prism and pyramid using cooperative learning model in the type group investigation with open ended problem approach can improve the ability of mathematical representation, which are : respones and learning outcomes shown in cycle II are primly goodand the students scoreof mathematical representation test capability in each cycle has improve signivicantly, until 80% on the last cycle. Moreover, the results showed that there are only 4 students from total 20 students who obtain score 68 which is the minimum completeness criteria set by the school . Student activities and learning management by the teacher in the learning process also increased to cycle II reaching an average of 82% and 81%. Therefore, learning by applying cooperative learning model in the type group investigation with open ended problem approach can improve the ability of mathematical representation

Abstract

This study aims to apply the RME-based ethnomatematics learning model to improve problem solving skills of prospective mathematics education teachers at the University of Bengkulu. This research is Classroom Action Research (CAR) with data collection techniques through student observation sheets and learning outcomes tests. Subjects in this study were 2A semester students at the University of Bengkulu in the 2017/2018 school year, totaling 22 people consisting of 6 male students and 16 female students. This study lasted two cycles through the RME-based ethnomatematics learning model with the following phases (1) orienting students to problems; (2) organizing students to study; (3) assisting independent and group investigations; (4) develop and present artifacts (works); (5) process analysis and evaluation. Based on this research, it was concluded before the implementation of the Ethnomatematics-based RME learning model, pre-action tests were conducted which resulted in an average value of 69.00 after the implementation of the ethnomatematics-based RME learning model could improve students' mathematical problem-solving ability with the problem solving ability test results. mathematics students get an increase in the average value of the first cycle of 70.77 to the second cycle of 79.59 and the percentage of mathematical problem solving ability increased from the first cycle of 81.82% to the second cycle of 95.45%

Abstract

This study aims to increase students' interest in learning mathematics. Based on the results of the pre-study, it was found that students were less interested in mathematics learning. This is caused by several factors including (1) mathematics learning so far generally lacks opportunities for students to develop strategic thinking skills, teachers only emphasize students to memorize all formulas or concepts without understanding their meanings, (2) learning is centered to the teacher (the use of lecture methods in mathematics learning) so that students are only used as learning objects, (3) in learning teachers rarely deliver material in real forms but only in abstract form. Therefore the learning series is designed using the Indonesian Realistic Mathematics Education (PMRI) learning approach to answer the phenomena that occur in pre-research. This study is a qualitative descriptive study. Subjects in this study were students of grade VII-A SMP Negeri 1 Pulau Morotai, North Maluku Province which numbered 25 people. The instruments used in this study were tests and interviews of teachers and students. The results showed that after the PMRI learning model was applied students felt interested and could improve mathematical knowledge and could also increase students' activeness in delivering ideas. For example, students dare to interact and negotiate between students and students and between students and teachers during the learning process. In addition, the PMRI learning approach can also reduce the level of abstractness of students in solving mathematical problems. This kind of thing does not happen to the learning by the mathematics teacher before. As a suggestion for teachers, in mathematics learning teachers should be able to connect the real world with mathematics learning because that can facilitate students to solve mathematical problems, and can increase students' interest in learning mathematics
