Abstract

The purpose of the research is to determine the ability of mathematical representation of students based on the level of socio mathematical norms owned by students. This research uses a descriptive qualitative method. The subjects were six students who had high, medium, and low sociomathematical norm categories.  This study used questionnaires, written tests, and interviews as data collection instruments. Rasch model method for questionnaires and written tests as a data analysis technique and in interviews analyzed using data reduction, data collection, and conclusion drawing using MAXQDA. The results of this research are: 1). Students with high sociomathematical norm categories have high mathematical representation abilities and so do students with medium and low sociomathematical norm levels, 2) the characteristics of students' representation abilities tend to have symbolic ability indicators and 3) the characteristics of students' sociomathematical norms in this study tend to mathematical communication indicators.

Abstract

Students' Higher Order Thinking Skills (HOTS), as seen from their learning outcomes, still need to be more optimal. This study aimed to describe applying the HOTS-based Discovery Learning model to improve student learning outcomes in curved-side geometric shapes. This research is a type of classroom action research. The subjects in this study were 9F class students at one of the public schools in Semarang. Data collection techniques are through written tests, while descriptive analysis is used. This research was conducted in 2 cycles. In cycle I, the level of completeness of students reached 57.14%, and in cycle II, the completeness reached 82.85%. The difference in mastery learning outcomes is 25.71%. From these results, using HOTS-based discovery learning is likely to improve the completeness of student learning outcomes in mathematics subject matter of curved side shapes.

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 study aims to describe the critical thinking skills of class VIII B students at a private junior high school in Jember Regency. This type of research uses descriptive qualitative. Data collection techniques used questionnaires, written tests, and interviews. The subjects used by the researchers were class VIII B at a private junior high school in Jember Regency. Subject data obtained 3 self-concept classifications including high self-concept, moderate self-concept, and low self-concept. Based on the three self-concept classifications, students' critical thinking skills are then analyzed in 4 indicators, namely interpretation, analysis, evaluation, and inference. The results of the study show that students' critical thinking skills in each self-concept have different classifications. Students with high (positive) self-concept have high (critical) critical thinking skills, students with moderate self-concept have moderate (sufficient) critical thinking skills, while students with low (negative) self-concept have critical thinking skills with low (lack) in problem-solving.

Abstract

Learning mathematics that emphasizes understanding concepts and solving problems requires learning media. The use of learning media is still low, so learning outcomes are far from the minimum completeness criteria (the student's lowest score), apart from learning media. Besides the media, learning models are essential to discover fun and not dull mathematics. This study aimed to improve learning achievement in data-building material through tangram media with the PjBL model for class IV at SD Negeri Gerih 7, East Java, Indonesia. The research method used was Collaborative Classroom Action Research. The subjects of this study were 23 students in grade IV at SD Negeri Gerih 7, East Java, Indonesia, in the 2022/2023 academic year. The test results obtained were in the form of pre-cycle class average values of 59.13, 64.78 in the results of the first cycle, and 77.82 in the results of the second cycle. It can be concluded that the PjBL learning model and the tangram media effectively improve the achievement results of fourth-grade students at SD Negeri Gerih 7, East Java, Indonesia.

Abstract

Mathematics education in this digital era requires innovative and creative learning models to improve the quality and creativity of students. The flipped classroom model has become one of the alternatives that can be implemented in mathematics education in the 21st century. This study aims to review several articles examining the flipped classroom model on elementary school student's mathematical creative thinking skills. The research method used is a literature review which begins with identifying research problems, searching for literature, evaluating data, and analyzing it. The literature review results show that the flipped classroom model has several advantages over the conventional learning model, such as increasing student engagement in the learning process and providing opportunities for students to develop creative thinking skills. In addition, using the flipped classroom model also positively influences students' abilities to solve measurement-related problems. Flipped classroom model provides a learning experience that is fluency, flexibility, originality, and elaboration. This article offers several recommendations for the development of the flipped classroom model in the future, such as the use of more varied learning media and the development of more interactive teaching materials. Therefore, this article can be a reference for educators and researchers interested in developing effective learning models to enhance students' mathematical creative thinking skills.
