This study aims to examine the scenario and implementation of online learning, the reaction of teachers and students to learning, the difficulties felt by students in completing the problem, as well as the obstacles experienced by teachers when doing online learning material system of linear equations two variables using CTL approach. This study is a qualitative descriptive research. This study…
The ability to solve problems is one of the abilities that students need to have in learning mathematics. Especially solving stories or non-routine questions, students really need to have the ability to solve these problems. Therefore, this study aims to determine and examine the ability to solve mathematical problems in solving one-variable linear equation (PLSV) material stories in junior hig…
Problem solving is one of the skills that is quite important for every student to have, because it is closely related to everyday life. To solve a mathematical problem, students are expected to be able to identify the adequacy of data, make mathematical forms, determine and implement strategies, present results, and apply mathematics in a meaningful way. Analysis of the difficulty of solving ma…
Critical thinking ability is an essential component of the four skills needed in the 21st century. However, this ability is still challenging to achieve well by students because of the lack of communication and cooperation during learning mathematics. Therefore, this experimental study with a posttest-only control design was conducted to determine the effect of using the jigsaw cooperative lear…
Evidence-based research on the effect of Realistic Mathematical Education (RME) has been conducted. However, whether differences in the measured variables alter the studies' effect sizes have not been explored. To fill this gap, it is necessary to conduct a meta-analysis study that can summarize the evidence for the effect of RME and analyze how the differences in the measured variables are ass…
This study aims to produce learning media based on a visual basic application of triangles and rectangles. This research is research and development. The method used in this research is a research and development method with a 4-D model (Four-D Model). This development model is modified into 3-D, only until the development stage (Develop). The instrument used in this study was a questionnaire u…
The use of mathematical software in learning has been widely applied. This meta-analysis study was conducted to examine the "Hawthorne effect", or the novelty of using mathematical software in learning. Related databases are sought for studies that qualify for examining the effects of using mathematical software compared to traditional teaching on students' mathematical abilities. Random-effect…
Although the literature has presented the overall effect of the RME approach, no specific studies have analyzed its relationship to the type of mathematical ability being measured. This meta-analysis study was conducted to measure the overall effect of RME and explore its relationship to types of mathematical ability and consider its implications. ERIC databases, sage publishing, springer publi…
Cabri is characterized by an attractive advantage and provides wide-ranging benefits in the teaching of mathematics. Although today there have been many studies on the edges of Cabri, experiments on Cabri-Express have not been widely explored. For this reason, a quasi-experimental study with a randomized posttest only design involving 80 grade VII junior high school students in Ruteng, Indonesi…
Comprehensive reviews of STEM (Science, Technology, Engineering, Mathematics) have not been explored much, causing many teachers not to realise the benefits of this approach for students. For that purpose, this meta-analysis study was conducted to understand the overall effect of STEM better. Empirical data were obtained from the ERIC, SAGE, SpringerLink, and Google Scholar databases. The searc…
