Analisis Pembelajaran Daring Matematika pada Siswa Kelas XII IPA SMA Negeri 7 Mataram

This study aims to describe the online mathematics learning process and to find out the mathematics learning outcomes in terms of the mathematics disposition of class XII IPA students at SMA Negeri 7 Mataram. This type of research is descriptive qualitative. All students of class XII IPA at SMA Negeri 7 Mataram are the population, where the sample size is 62 students who were selected by cluster random sampling rule. Data collection used a questionnaire, interview and documentation study. From this research, the results show that: (1) The learning process carried out by the teacher changes from direct learning to online learning. In the online learning process, there are several difficulties experienced by students, including students who do not understand the material presented by the teacher, whether the material is delivered in the form of a pdf or video that has been shared. In implementing the online learning process the teacher is not the only source of learning so students are actively looking for other learning reference sources such as videos on YouTube and websites. Assessment of learning outcomes is carried out by providing a written test of the test resulting in that there is no increase in student learning outcomes during learning with an online system. The implementation of online learning cannot be separated from the supervision of parents and teachers. (2) There is a correlation between final semester test scores with students' mathematical dispositions.

This study aims to determine how the ability of mathematical problem solving in the Cartesian coordinate system material in terms of differences in divergent and convergent thinking patterns in class VIII students in semester 1 of SMP Negeri 1 Kediri in the 2019/2020 academic year. This research is a descriptive study using a quantitative approach. The instruments used in this study were the thinking character questionnaire instrument and the problem solving ability test instrument. The thinking character questionnaire instrument was used to select research samples that met the criteria for divergent thinking and convergent thinking. In this study, 11 students thought divergent and 12 students thought convergent. The problem-solving ability test instrument was used to determine the problem-solving ability of the research sample as measured by Polya's assessment guidelines, namely (1) understanding the questions, (2) planning solutions, (3) solving problems, and (4) checking. The results showed that there was no difference in the average score of problem-solving abilities between students with divergent and convergent thinking patterns, namely 66.19 and 66.73. The only difference lies in the steps each student takes. This shows that different mindsets do not affect a person's ability to solve a problem.

Pengaruh Model Pembelajaran Kooperatif Tipe Group Investigation (GI) Terhadap Hasil Belajar Matematika Siswa SMP

This research is a quasi-experimental study that aims to determine the effect of the Group Investigation (GI) type of cooperative learning model on the mathematics learning outcomes of junior high school students. The population in this study were all VIII grade students of SMP Negeri 2 Kediri, which were divided into three classes. The research sample of two classes was taken by the purposive sampling technique. The data collection technique using tests and observation sheets. The experimental class uses a Group Investigation (GI) type of cooperative learning model and the control class uses a direct learning model. The sample in the study was class VIII-A as the experimental class and class VIIIB as the control class. The normality test and homogeneity test showed that the two samples were normally distributed and homogeneous. The data analysis using t test with show and so is rejected. So it can be concluded that there is an effect of the Group Investigation (GI) type of cooperative learning model on students mathematics learning outcomes. To find out how much the effect of the Group Investigation (GI) type of cooperative learning model has on the students mathematics learning outcomes, it can be done by using effect size calculations with Cohen’s formula and the calculation results are 1.18 including in the high category. This means that the application of the Group Investigation (GI) type of cooperative learning model has a high effect on the mathematics learning outcomes of VIII grade students of SMP Negeri 2 kediri academic year 2021/2022
