The Influence of Jigsaw Cooperative Learning Model on Mathematical Representation Ability and Student Learning Motivation at PAB 10 Sampali Private Elementary School. Thesis. Medan: UNIMED Postgraduate Program, 2020. This study aims to determine 1) the magnitude of the influence of the learning model on students' mathematical representation abilities and learning motivation; 2) the magnitude of the influence of early mathematical abilities on the ability of mathematical representation and student learning motivation; and 3) the interaction between the learning model and the initial mathematical ability of the mathematical representation ability and student learning motivation. The research was conducted in private SD PAB 10 Sampali with a sample of 2 classes with each class totaling 35 students. This research is a type of experimental research all with a 2 × 2 factorial design. The results showed that there is an effect of the learning model on the students 'mathematical representation ability, where the jigsaw cooperative learning model has a 9.1% higher effect on students' mathematical representation abilities than the expository learning model, there is an effect of initial mathematical ability on students 'mathematical representation abilities, where the high initial mathematical ability of students has an 11.5% higher effect on students' mathematical representation abilities compared to low initial mathematical abilities, there is no interaction between the learning model and the students 'mathematical initial ability to the students' mathematical representation ability.
This study aims to develop appropriate and effective digital-based smart card learning media for class II students of Al Hidayah Sidomulyo Private Madrasah Ibtidaiyah (MIS). The background of this study is the lack of use of learning media used in learning Indonesian. Teachers only use lecture methods and learning media that are less supportive. Due to the limited knowledge of teachers in making learning media interesting for students. This type of research is research and development RD (Research and Development). The development model used in this study is the ADDIE model, which has five stages, namely: (a) analysis; (b) design; (c) development; (d) implementation; (e) evaluation. Data collection techniques in this study were non-test techniques, namely observation, questionnaires, and interviews. The data analysis techniques used in this study are (1) analysis of digital-based smart card learning media; (2) analysis of the effectiveness of digital-based smart card learning media. Based on data analysis, it shows that the digital-based smart card learning media developed is feasible and effective for second-grade students and can improve student learning outcomes.
This research is research Research and Development (R&D). This study uses the Four D development model. In this study it was only carried out at the development stage. This research was conducted in class II at SD IT Hamas Stabat. The research was carried out in the even semester of the 2021/2022 school year. The subjects in this study were 20 grade II students at SDIT Hamas, 11 male students and 9 female students. The object in this study is flipbook based smart card learning media. Data collection techniques in this study were observation, interviews, tests, questionnaires and documentation. The stages in the four D development model are define, design, develop, disseminate. The results of the validation test by experts, namely media experts, were 89.00%, while the results of the material validation test were 88.06%. The results of material validation and media validation are categorized as very feasible. The results of student learning motivation on flipbook-based smart card learning media amounted to 79.07%.
The research objective was to find out how the critical thinking skills and literacy skills of elementary school students relate. The research method used is a correlational research method with a quantitative approach. Aims to reveal the relationship between variables. Population to be studied (Sugiyono, 2019). The population in this study were 215 fifth grade elementary school students consisting of 8 schools. The sampling technique used by researchers is simple random sampling technique. The sample of this research is 140 students. Data collection techniques in this study were in the form of tests of critical thinking skills and tests of scientific literacy abilities. The data processing carried out consisted of three stages, namely data description and categorization, analysis prerequisite testing, and hypothesis testing. Based on the research that has been done, it can be concluded that: 1) There is a relationship between scientific literacy abilities and students' critical thinking skills with a correlation coefficient of 0.368; 2) Scientific literacy ability influences or contributes to students' critical thinking skills by 13.6%; 3) Scientific literacy ability has a positive and significant relationship to students' critical thinking skills with a significance value based on a simple linear regression test <5%.
