Abstract

This article explains the results of research on the influence of everyday mathematics learning models on critical thinking skills of Class XI students of SMA Negeri 4 Seluma in the 2019/2020 Academic Year. This type of research is experimental research with quasi experimental. This research was conducted at SMAN 4 Seluma in the odd semester of the 2019/2020 school year with a population of all class XI and sample classes XI MIA1, XI MIA2, XI MIA3, and XI IIS2. Research data were analyzed using Ancova test. The results showed that there were differences in critical thinking skills between students taught with everyday mathematics and conventional learning models after controlling students' initial abilities with p-value = 0.00 <0.05, there were differences in critical thinking between students whose cognitive styles were Field Independent (FI), and Field Dependent (FD) cognitive style after controlling students 'initial abilities with p-value = 0.00 <0.05, there is an influence of learning model interaction and cognitive style on critical thinking skills after controlling students' initial abilities with grades p-value = 0.00 <0.05, there is a linear influence of students 'initial covariate ability on critical thinking skills with p-value = 0.00 <0.05, students' initial ability, everyday mathematics learning model and cognitive style together - the same effect on critical thinking skills p-value = 0.00 <0.05

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

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

Ethnomatemics-based mathematics concept implementation can be carried out through constructivism-based learning such as realistic mathematics, problem-based and learning with a scientific approach. This research purpose to explore the form of ethnomatemics on the woven cabbage leaves of the Tutuwaru community and analyze the process of understanding mathematics from the perspective of indigenous people and indigenous knowledge and examine the development of woven form ethnomatatics in school mathematics. The method used in this research is descriptive qualitative research. The subjects are 2 members of the weaving community, while the objects of research are Nyiru (winnowing-basket), Topi (hat), Keranjang dan Bakul (basket). The results showed that the form of weaving from a typical local Koli (cabbage) tree, could be connected with several mathematical concepts such as basic geometry and arithmetic. The hexagonal concept based on the understanding of multiples is an "indegious knowledge" that exists in the Tutuwaru community in constructing the form of nyiru-woven, reflection, points, lines and tessellation. These mathematical ideas can be used as context in school mathematics learning

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh metode Problem Based Learning (PBL) dan metode konvensional terhadap kemampuan pemecahan masalah dan self efficacy matematis mahasiswa. Jenis penelitian ini pretest-postest control group design dengan kategori quasi eksperiment. Hasil penelitian uji independent sample t-tes menunjukan bahwa metode PBL lebih efektif dari pada metode konvensional dalam perkuliahan matematika teknik. Hasil uji menunjukan bahwa sig (2-tailed) sebesar 0,000 < 0,005. Dengan kata lain, ada perbedaan antara metode PBL dengan konvensional terhadap kemampuan pemecahan masalah mahasiswa. Besar perbedaannya dari kedua kelas dapat dilihat pada hasil mean postes kelas ekperimen 75,23 dan mean postes kelas kontrol 54,32. Artinya, menunjukan bahwa penerapan metode Problem Based Learning berpengaruh terhadap kemampuan pemecahan masalah mahasiswa dibandigkan metode konvensional. Hal ini linier dengan hasil sebaran angket self efficacy mahasiswa yang diterapkan metode Problem Based Leaning perbedaan dari mahasiswa yang menggunakan metode konvensional. Hasil uji menunjukan Based on Mean adalah 0,03>0,05
