Abstract

The snow cube throwing learning was developed to find patterns, make hypotheses, and draw conclusions based on their findings in problem-solving. Students are given five types of teaching materials with similar problems to improve students' mathematical analogy skills. This study aims to analyze the differences in the improvement of mathematical analogy abilities that received snow cube throwing based on exploration (SCTBE), exploratory and expository learning reviewed as a whole, and by school category. This study is a quasi-experimental study with a non-equivalent pretest and posttest control-group design. The research subjects were students of class VIII from three schools in Cimahi City. Overall, the results showed that students who received SCTBE and expository learning improved mathematical analogy abilities and were better than students who received exploratory learning. Reviewed by school category, SCTBE learning is more suitable for middle category schools with active and independent characteristics.

Abstract

Misconceptions in mathematics education, particularly in numeracy, are a significant issue that needs to be addressed urgently to improve the quality of education in Indonesia. This research aims to reduce students' misconceptions by developing and implementing a 4-Tier diagnostic test based on Education for Sustainable Development (ESD) supported by Arduino tools in a Problem Based Learning (PBL) model. The method used is mixed methods with a population of 10th-grade high school students and a purposive sampling technique. The research instruments include a 4-Tier diagnostic test and observation sheets. Data were analyzed qualitatively and quantitatively using the concurrent embedded strategy model and the Ploomp research design. The results of the study show that the 4-Tier diagnostic test is effective in mapping students' conceptual understanding and significantly reducing numeracy misconceptions. The implementation of the ESD-based PBL model also proved to enhance students' numeracy skills. This research indicates that integrating diagnostic tests into the curriculum is crucial for improving the quality of learning and students' understanding. The use of Arduino in trigonometry learning increases students' motivation and engagement. Thus, this learning model can be a solution to enhance students' competencies in facing the challenges of globalization and technology in line with UNESCO's Agenda 2030

Abstract

This training is motivated by the advantages of canva as a graphic design tool that facilitates the creation of engaging and effective digital teaching materials. With its intuitive features, Canva offers an innovative solution for developing educational content that can enhance student engagement, highlighting the need for teacher training. This training aims to enhance teachers' skills in using Canva to create appealing and interactive instructional materials and evaluate its impact on the quality of educational content. The training involved 51 participants, consisting of mathematics teachers within the scope of the West Bandung Regency Education Office and students from the Master of Mathematics Education program. The method used was Participatory Action Research, involving the active participation of participants in the learning and evaluation process. The training was conducted in a hybrid format, combining face-to-face and online sessions for greater flexibility and wider reach. Evaluation results indicated that teachers' ability to create teaching materials using Canva significantly improved, with an average score above 80. Discussion of the results revealed that this training was effective in enhancing teachers' skills and had a positive impact on the quality of instructional materials. This activity concludes that the Canva training successfully achieved its objectives, although challenges such as time constraints and access issues need to be addressed. Recommended follow-up actions include enhancing technical support and extending the training duration to maximize benefits for participants in the future.

Abstract

Numeracy skills play a crucial role in various aspects of life, both in mathematical learning and in daily life. Numeracy is the key to understanding and mastering various mathematical concepts. However, several research findings indicate that these skills are still relatively low. The low numeracy skills are attributed to the low engagement of students in mathematical learning. When students feel actively engaged in learning, they tend to be more motivated to learn and better able to understand the concepts taught. One effort to engage students in learning activities is by interestingly presenting learning content. Digital game-based learning is expected to improve numeracy skills and student engagement in mathematical learning. This study is a mixed-method research. The participants in this study were fourth-grade elementary school students divided into two groups: the experimental group and the control group. The instruments used were numeracy ability tests and observation sheets. The results of the study indicate that (1) the numeracy skills of students who received digital game-based learning are better than those of students who received traditional learning; (2) there are differences in the mean numeracy skills of students based on the intensity of playing games; and (3) Student engagement in digital game-based learning is classified as very high.

Abstract

This research was motivated by the fact that the mathematical problem-solving ability of junior high school students during the Covid-19 pandemic in Indonesia was low. The strategy and approach used in learning mathematics are success factors in the mathematics learning process. One of the objectives of this research is to analyze the mathematical problem-solving ability of junior high school students using mobile learning with the Microsoft Kaizala application. The method used in this research is an experiment with a Pre-Experimental Design Research and One-Group Pretest-Posttest Design Research Design. The research was conducted at SMPN 50 Satap Oku, Ogan Komering Ulu Regency, South Sumatra Province. The results showed that the final mathematical problem-solving ability of students who received learning using mobile learning with the Microsoft Kaizala application was better than the students’ initial mathematical problem-solving ability and the average percentage of students’ mathematical problem-solving ability achievement after using the Microsoft Kaizala application was 85.16% (excellent). It means that the students’ problem-solving ability is getting better after using mobile learning with Microsoft Kaizala application.
