The purpose of this research was to intimidated LMM (Learners’ Mental Model) of work and energy. The mental model can be used to considered more extremely apparatus of misconceptions. The research method is a case study with descriptive quantitative analysis. The samples are 30 tenth grade students (14 boys and 16 girls, their ages were middling 16 years-old) at one of senior high school in Bandung. The research sample used cluster random sampling technique or random class. LMM was analysis through two-tier test in the form of open-ended questions as many as 5 questions. The data investigation was approved purchasable in two stages. In the first stage the analysis learners level of understanding and in the second stage the analysis learners model of understanding. The result illustrations that mental models have been identified in the three categories, that are, 1) Scientific 26,7%, 2) Synthetic 16%, 3) Initial 57,3%. In conclusion, mental model of the initial category is higher than other categories.
In order to understand the content of mathematics, students must have an understanding of mathematical concepts. This study aims to examine how Treffinger learning can improve students' ability to understand mathematical concepts in terms of self-efficacy. This type of quantitative research is an approach designed for this experimental research. Class VII students of MTsN 1 Pandeglang are the population or object under study. The research design applied to the study was the Pretest-Posttest Nonequivalent Control Group Design. Sampling was determined using purposive sampling technique, class VII B and VII F were selected to serve as the experimental class and control class. Validated questionnaires and tests are useful research tools for collecting data on students' self-efficacy and ability to understand mathematical concepts. The hypothesis test in this study applies the Two-Way ANOVA test. The results of the study revealed that the Treffinger learning model provided an increase in the ability to understand mathematical concepts. What's more, there is a contribution between self-efficacy towards students' understanding of mathematics concepts.
Learning that takes place, especially science subjects, is different from the mandate of the 2013 curriculum. The science knowledge competence of elementary school students still needs to improve. This study aims to analyze the effect of the SFAE learning model based on Tri Kaya Parisudha on students' science knowledge competence. This type of research is a quasi-experiment using a nonequivalent control group design. The population of this study was all grade V students, as many as 443 students, with sample determination using a cluster random sampling technique. The data collection method used an essay-type test. The research data were analyzed using descriptive statistical techniques and inferential statistical analysis (t-test). The results of hypothesis testing using the t-test technique with polled variance formula obtained a t-count equal to 4.67 more than the t-table equal to 1.998 at a 5% significance level with dk equal to 63, so Ha is accepted, and H0 is rejected. So it is concluded that the SFAE learning model based on Tri Kaya Parisudha affects students' science knowledge competence. This research implies that the SFAE learning model based on Tri Kaya Parisudha is expected to be an innovative learning model to encourage student activeness and improve learning outcomes.
Low students' physics learning outcomes are an important and major problem in achieving competency. The purpose of this research was to find out whether there was a significant effect of the Student Facilitator And Explaining (SFAE) cooperative learning model on the physics learning outcomes of class XI students of Senior High School. The type of research conducted was Quasi Experimental Research with the Post-test Only Control Group Design research design. In this study, the population was all class XI Mathematics and Natural Sains students at Senior High School who were enrolled in the 2022/2023 academic year. The sample of this study was class XI Mathematics and Natural Sains 1 which was the experimental class and class XI Mathematics and Natural Sains 2 which was the control class. The research instrument consisted of a posttest and an attitude assessment sheet. The data analyzed in this study used descriptive analysis and a two-way similarity test at a significant level of 0.05 for student competencies consisting of knowledge competencies and that is, there is a significant effect of applying the Cooperative learning model of the Student Facilitator And Explaining (SFAE) type. ) on the physics learning outcomes of class XI students of Senior High School. This is supported by the results of data analysis on each of the knowledge and attitude competencies. With the two average similarity tests, the value of t count > t table was obtained, for knowledge competencies 2.05 > 2.00, and for attitude competencies 3.08 > 2.00.
The author is writing describe development of 3D Learning media in the form of pop-up book for Bahasa Indonesia lesson with lesson material development of transportation technology for third grader elementary school. The learning media development in this study obtained its feasibility throughh media expert and material expert. This writting is in the form of qualitative using the ADDIE method (Analysis, Design, Development, Implementation, Evaluation). The author uses data collection techniques based on validity tests conducted by media masterful and material masterful. The results of writing a 3D learning media pop-up book for Indonesian subjects material development of third-grade elementary school technology that is included in the category of feasible/valid with the results of the media expert test reaches a percentage of 83.92% with validd criteria. While the results of the expert material test I reached a percentage of 77.08% with sufficient criteria valid/feasible and the results of the expert test material II reached a percentage of 100% with valid criteria / feasible. Based on the validity test, it can be summarized that the Pop-Up media that was developed entered into the criteria is valid/feasible so that this media is feasible and can be implemented in the classroom prac tice.Keywords: 3D Learning media, Pop-Up Book, Bahasa Indonesia, Development of Transportation Technology
