Abstract

This research was conducted in one of the elementary schools in the Wates, Kulon Progo area. This study aims to develop learning media based on snakes and ladders mathematics Augmented Reality for fifth grade students and describes the feasibility of mathematics-based snakes and ladders learning media Augmented Reality for fifth grade students. This development research uses the ADDIE development research model which is modified into three steps, namely Analysis, Design and Development. The methods used are qualitative methods and quantitative methods. The results showed that the learning media for snakes and ladders is mathematics based Augmented Reality meets the eligibility criteria as evidenced by the validation results of media experts getting an average score percentage of 99.57% with the "Very Eligible" criteria, the material expert validation results get an average score percentage of 94.29% with the "Very Eligible" criteria and the results of the questionnaire the media trial obtained an average score of student responses as a whole, namely 96.54% with the "Very Good" criterion. Then, the results of observations and interviews showed that teachers and students gave a positive response to the mathematics-based snakes and ladders media Augmented Reality. Thus, learning media based on snakes and ladders mathematics Augmented Reality can be used as an alternative learning media in class V elementary school.

Abstract

Many universities apply student support services to undergraduate (UG) students, but some postgraduate (PG) cases need it. South African universities have intensified PG admissions. PG students admitted with a minimum admission mark are not PG-ready. For the Bachelor of Science Honours (BSc Honours) in Statistics (Stats) that requires intense Math conceptual knowledge to apply to Stats concepts, where competition is high, only top students can be competitive. In South Africa, the job market prioritizes graduates from historically white higher education institutions (HEIs), and formerly black and newer university graduates’ struggle. Non-stop students from the latter universities are not easily employed, so they need a stimulus. This study focuses on BSc Honours (Stats) students who perform low for intervention to improve their performance. Measures were proposed for student conduct and behavior to enable lecturers to constantly stimulate the teaching and monitor and evaluate progress while continuously assessing the students. The study followed an experimental design. Students were ordered to practice with module exercises using statistical software packages in the computer laboratory. Exceedingly high pass rates of 100% were realized. The methods were viewed as effective and beneficial.

Abstract

This research is a quasi-experimental research that aims to determine whether online learning based on WhatsApp Group with LKPD assistance is more effective than  with-based online learning WhatsApp Group without the assistance of LKPD in terms of student learning motivation towards mathematics learning outcomes of class VII students at SMP Negeri 3 Jetis. The data analysis technique used t-test, prerequisite test in the form of normality test and homogeneity test, Mann-Whitney test, and Kruskal Wallis test. The result of this study is that online learning based on WhatsApp Group with the assistance of LKPD is as effective as online learning based on WhatsApp Group without the assistance of LKPD and the mathematics learning outcomes of students with high motivation are better than students with moderate and low motivation.

Abstract

This study aims to determine the ability of mathematical representation of students in geometry material after learning with the help of GeoGebra. This research is motivated by students' difficulty in interpreting geometric shapes. This research is qualitative research with a descriptive approach. The subjects in this study were 3 (three) class XII students who had obtained three-dimensional material with the help of GeoGebra applications. Researchers carry out the data collection process by providing mathematical representation ability test questions, conducting interviews, and taking documentation. The data obtained in this study were analyzed using specialized triangulation-checking techniques. Based on the results of data analysis and the effects of interviews with all research subjects, it can be concluded that learning geometry with the help of GeoGebra applications can improve mathematical representation capabilities. Three mathematical representation abilities, namely visual representation, equation or expression, and written words or texts, are possessed by students after learning geometry with the help of GeoGebra applications.

Abstract

This study aims to describe the process of solving mathematical problems in the subjects of a two-variable linear equation system in terms of field-dependent cognitive style. The type of research used is descriptive qualitative research. The research subjects were 15 grade VIII students in one of the public junior high schools in Cimahi City. In this study, the instrument used was a problem-solving test consisting of 2 questions on the material of a two-variable linear equation system and interviews for 3 students with field dependent cognitive style. The results showed that the steps of solving mathematical problems of students with cognitive style field dependent were categorized as good at the stage of understanding the problem and re-examining, categorized enough at the stage of planning completion, and categorized less at the stage of implementing the completion plan. This means, if field dependent students can understand the problem or problem, it will affect the next step.

Abstract

The success of character education during the Covid 19 pandemic experienced many obstacles, considering that learning at school was carried out online. However, through the online system, the massive development of information technology may erode the noble cultural character of students. Efforts to create students with characteristics that match the personality of the Indonesian nation during the Covid 19 pandemic are not enough through the implementation of learning based on the curriculum that has been implemented. These efforts can be made through ethnomathematics, namely integrating cultural elements into learning mathematics. Inquiry learning is done through investigation and discovery to develop conceptual understanding. This study aims to develop an online inquiry mathematics learning model based on Javanese cultural ethnomathematics. The research method to be carried out is Research and Development, which refers to the educational development model from Plomp. The construction phase begins with coordination activities with the school where the research trials are carried out. Then a small-scale trial was carried out by carrying out online learning using the learning model that had been developed. Small-scale trials were conducted in four schools. Furthermore, the implementation of large-scale trials in eight schools. The twelve schools were taken from junior high schools in the Provinces of DIY, Central Java, and East Java. The test, evaluation, and revision stages continue the previous stage. The model is validated by a judgment expert, namely an expert in mathematics learning models, to test whether the developed model can be understood and accepted by users. The study's results showed that the user's assessment of the Javanese ethnomathematics-based inquiry learning model showed excellent results. Users state that they understand the learning model developed, including the learning model's syntax, social systems, learning principles, learning support systems, instructional impacts, and accompanying impacts. The user ratings of the learning module show high scores in the introductory, content, evaluation, and closing aspects. Users also stated good results for student worksheets, including aspects of the completeness of student worksheet components, content, materials, language, and learning model requirements.

Abstract

Learning mathematics is considered a difficult subject for students. Learning difficulties experienced by students often have an impact on the lack of awareness of the importance of mathematics in students' daily life. Optimization of learning mathematics with problem-based learning can be applied using the 3N teachings of Tamansiswa concepts, namely Niteni, Nirokke, Nambahi. This research is qualitative in the form of a literature review. This article describes how teachers can optimize PBL with Tamansiswa teachings in learning mathematics so that students become enjoy, more effortless, and responsive in applying mathematical concepts in daily life.
