Abstract

Abstract This study aims to develop teaching materials for flat shapes using a realistic mathematics education approach to teach students' mathematical problem solving skills and to determine the quality of teaching materials in terms of validity, practicality, and effectiveness. This research is a development research with the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The subjects in this study were 28 grade VIII students of SMP Negeri 7 Padang Sidempuan. The research instrument used to measure the quality of teaching materials was in the form of expert validation questionnaires, student response questionnaires and post-test results of students' mathematical problem solving abilities. The expert validation questionnaire was used to measure the validity of the teaching materials while the student response questionnaire was used to measure the practicality of the teaching materials and the post-test results of students' mathematical solving abilities were used to measure the effectiveness of the class VIII students' teaching materials at SMP Negeri 7 Padang Sidempuan. The results of this study indicate that the quality of teaching materials is seen from the validation assessment of material experts with an average score of 75.5%, for the assessment of media experts with an average score of 78.33%, and for the assessment of linguists with an average score amounted to 90.67% with each score included in the eligible criteria. The overall results of the expert's assessment show that the teaching materials developed have "good" (decent) criteria based on the assessment by 6 experts with a percentage score of 81.5% in the "very valid" criteria. And the results of the questionnaire responses of students to teaching materials seen from the aspect of practicality with a percentage score of 92.78% in the "very practical" criteria and the post-test results of students' mathematical solving abilities seen from the aspect of effectiveness with an average score of 74.46 in the category " effective. So it can be concluded that the overall results of the study indicate that the teaching materials of flat shapes with a realistic mathematical approach to teach students' mathematical problem solving skills are valid, practical, effective and suitable to be used as learning tools.

Abstract

Abstract This study aims to know the description of students’ ability to understand mathematics and what the factors that affect students’ ability to understand mathematics in terms of learning difficulties during the Covid-19 Pandemic. This research was conducted at the Sosorgonting Adventist Private Elementary School. The type of research used qualitative method. Data collection techniques used observation, questionnaires, interviews, tests and documentation. Data analysis techniques used data reduction, data presentation and conclusion drawing. The results showed that the students' ability to understand mathematics was still low, 10 students did not complete and 3 students completed the specified KKM score. The results of the distributed questionnaires obtained showed the average is 72.31 which mean that students have learning difficulties in the high category. Students' ability to understand mathematics is influenced by several factors, namely external and internal factors. Some external factors include time constraints, family pressure, lack of support in the surrounding environment and financial problems. In addition, there are internal factors related to discipline, interests, and physical health.

Abstract

Abstract This study aims to determine whether there is an effectiveness of applying RME learning model on the mathematical communication skills at the eighth grade students of SMP Swasta Advent Barus. The research used an experimental method by applying one group pretest posttest design. The sample of this study is taken by using total sampling technique, the eleventh grade students of SMP Swasta Advent Barus which includes 35 students. Observation and tests are used in collecting the data. Observation sheets show the applying of RME learning model has an average of 2.93 (good category) while students' mathematical communication skills before applying RME learning model has an average of 64.70 (enough category) and after applying RME learning has an average of 72.13 (good category). Furthermore, based on the calculation of the t-test (SPSS of version 2017) it shows the value of Sig. (2-tailed) is 0.000 < 0.005, classical completeness is 51.43% and the N-Gain value shows 0.27 (low category). It means, there is any effectiveness of appying RME learning model on students' mathematical communication skills in the low category at the eighth grade students of Barus Adventist Private Junior High School.
