Abstract

The reality that occurs shows that students' mathematics learning achievement has not been in line with expectations. Students' mathematics learning outcomes based on test scores, there are still many students whose scores are below the specified KKM, which is 77. If you pay attention when learning takes place, it seems that many students are less interested in learning mathematics. Especially if the math class is at the last hour. This is one of the obstacles students are not motivated to learn mathematics. In addition, learning activities have not optimized student-centered learning models, so that the learning process feels less interesting so that students' understanding of mathematical concepts is still low. This study aims to determine the effect of the TTW strategy in improving learning outcomes in terms of understanding students' mathematical concepts. This type of research is a quasi-experimental research (quasi-experimental). The population in this study were students of class XI SMAN 1 Painan, class XI IIS 4 as the experimental class and class XI IIS 1 as the control class. The instrument used is a concept understanding test. The results of the hypothesis in this study are that students' understanding of mathematical concepts who take part in learning using the TTW type cooperative learning model is higher than students who use conventional learning. This means that the TTW type cooperative learning model has a good effect on students' conceptual understanding.

Abstract

The mathematics learning outcomes of most of the VIII grade students of MTsN Lubuk Buaya have not reached the Minimum Completeness Criteria. One of the efforts that can be made by the teacher to activate students in learning which can improve student learning outcomes is to apply an active learning strategy of the Listener Team type using Microsoft Powerpoint media. The purpose of this study was to determine the activities and learning outcomes of students' mathematics by implementing an active learning strategy of Listening Team type using Microsoft Powerpoint media. This research is a quasi-experimental research. The population of this study were students of class VIII MTsN Lubuk Buaya. The sampling technique was done by drawing numbers and the selected samples were students of class VIII.2 as the experimental class and class VIII.3 as the control class. The data were first tested for normality, homogeneity test and analysis of variance. The results showed that the mathematics learning outcomes of students who used the application of the Listener Team type active learning strategy using Microsoft Powerpoint media were better than conventional learning in class VIII MTsN Lubuk Buaya. The student activity data was obtained through observations at each meeting in the experimental class which showed that students' mathematics learning activities increased after being taught by implementing an active learning strategy of Listening Team type using Microsoft Powerpoint media in class VIII MTsN Lubuk Buaya.

Abstract

This research is motivated by the monotonous teacher teaching method, which requires students to remember the material without asking to understand the concept of learning mathematics. So that mathematics learning has not achieved the expected results. To solve this problem, the Discovery Learning model (guided discovery) is a solution that will be tried. The goal is that there is a change in student learning attitudes and teacher teaching so that they will get good learning outcomes and achieve KKM. This research model uses a quantitative approach with experimental methods, with a random research design on the subject. The population in this study were students of class VII MTsS Darussalam Amping Parak for the 2020/2021 academic year which consisted of two classes. The sampling technique was carried out randomly, class VIIB as the experimental class and VIIA as the control class. The instrument used in this study was a reliable essay final test. The data analysis technique used is the one-party t test. Hypothesis testing using the one-party t-test, obtained t = 3.21 and t table = 1.67. Because tcount> ttable, this research hypothesis is accepted. So, it can be concluded that the mathematics learning outcomes of students using the Discovery Learning Model are better than the mathematics learning outcomes of students taught using conventional learning in class VII students of MTsS Darussalam Amping Parak for the 2020/2021 academic year

Abstract

This research was conducted based on the facts showing that the students’ ability in mathematical reasoning problem was still low in class X of SMA Negeri Painan. This could be seen from the result of observation and analysis of their achivement on mathematic reasoning test. To overcome this problem, Problem Based Instruction model was applied. This research was designed for revealing the effect of using Problem Based Instruction model on the students’ reasoning abilities the in class X of SMA Negeri Painan. This was a quasi experimental research. The population of the research was the students in class X of SMA Negeri Painan. By using Random Sampling technique, class X.6 of SMA Negeri 2 Painan was chosen as the experimental group and class X.4 of SMA Negeri 2 Painan was chosen as the control group. The instruments of the research were a questionnaire of creativity to see the students’ creativity in learning and a test to see their ability in mathematic reasoning. Based on the result of the research, some conclusions were drawn. First, the reasoning abilities of the students taught by using Problem Based Instruction model was better than that of students taught by using conventional model. Second, the reasoning ability of the students having high and low kreativity taught by using Problem Based Instruction model was better than that of students taught by using conventional model.

Abstract

Mathematical disposition is an attitude that students need as students to survive in facing problems, take responsibility in their learning, and develop good work habits in mathematics. However, the mathematical disposition of STKIP Pesisir Selatan students while attending basic statistics lectures is still far from expectations. For this reason, a learning model is needed to overcome them. One model that can be used is problem based learning. The purpose of this study is to find out how to increase the mathematical disposition of STKIP Pesisir Selatan students in basic statistics courses before and after learning problem based learning and whether the improvement is significant. All populations were sampled, namely students of mathematics and ICT education courses taking basic statistics courses in the even semester 2018/2019. This type of research is Quasi Exspriment with One Group Pretest-Posttest Design research design. The research data were obtained from a questionnaire given before and after the experiments were carried out. Data analysis used N-gain test to measure the increase in mathematical disposition and continued by paired sample t test to see the significance of the increase. The results of the analysis show that the increase in mathematical disposition of STKIP Pesisir Selatan students with the application of problem based learning in basic statistical subjects has increased quite well, but the increase that occurred was not significant.

Abstract

This study aims to describe students’ difficulties in solving the problem solving mathematic problem and its causal factors. This research is qualitative descriptive research. The subject of this research is the students of class VII MTsN 12 Pesisir Selatan located in Ranah Pesisir subdistrict with the sample chosen by purposive sampling. Data obtained through tests, interviews and observations. Data validated by triangulation method. The data analysis framework is reviewed from the problem solving steps of understanding problem, problem solving strategy and problem solving result and interpretation of problem solving result (conclusion). Data analysis techniques used in this study is the percentage and data analysis techniques according to Milles and Hubermen for the analysis of difficulty and factors causing the difficulty.The results of data analysis show that, first difficulties experienced by students in understanding the problem that is identifying what is known and asked and make problems in symbol or mathematical model. Second, the students have difficulties in making the settlement strategy because they can not relate the concept to the problem or the ability of the students' mathematical connection is still weak. Third, students have difficulty in calculating the settlement because of difficulties in understanding the concept. Fourth, students who have difficulty in the previous step also have difficulty in interpreting the answers correctly
