2024-05-03T11:29:17+07:00

This research is motivated by concerns about low student motivation in the educational environment. The main objectives of this study are: 1) to understand the level of motivation among the majority of high school students in Lebak Banten Regency in learning mathematics using the Wordwall media; 2) to explore differences in the level of student motivation based on the ARCS model in mathematics learning utilizing the Wordwall media, considering sex factors; 3) to analyze the percentage of each ARCS aspect contributing to the level of motivation in mathematics learning using the Wordwall media; 4) to identify how the percentage of each ARCS aspect affects the level of motivation in mathematics learning using the Wordwall media, considering sex differences; 5) to examine the influence of Wordwall-based mathematics learning on sex-based motivation seen from the ARCS model. The research method used is quantitative with a quasi-experimental approach and a One-Group Pretest-Posttest research design. The data analysis results show that female students' motivation tends to be higher than that of male students, with the motivation percentage of female students being higher in each aspect of ARCS motivation. The Satisfaction aspect has the highest percentage, which is 78.53%. There is a significant increase in the motivation of male and female students from pretest to posttest. The increase is seen in all four aspects of ARCS motivation. In male students, there is an increase from an average of 47.36% to 75.00%, while in female students, there is an increase from 54.25% to 83.16%. Additionally, there is an influence before and after Wordwall-based mathematics learning based on sex seen from the ARCS model

Analysis of Mathematical Critical Thinking Ability in View of Personality Type in Solving Literacy and Numeracy Questions

2024-06-03T13:25:12+07:00

Critical thinking is an essential outcome of the learning process and a crucial tool for knowledge growth. This study aims to analyze the mathematical critical thinking skills of students based on their personality types when solving problems involving literacy and numeracy. A qualitative research method with a descriptive approach was employed. Four informants from the 8th grade, representing extrovert and introvert personality types, participated in the study. Their personalities were identified using the Eysenck Personality Inventory (EPI) non-test instrument. Subsequently, a validated and reliable critical thinking assessment tool was administered. The findings indicate that overall, both extrovert and introvert students can fulfill the four indicators of critical thinking skills proposed by Facione (1990): interpretation, analysis, evaluation, and inference. Extrovert students excelled in the interpretation and analysis indicators, demonstrating their ability to comprehend and translate information from problems into mathematical models. However, extrovert students often made mistakes in the evaluation indicator, lacking accuracy in calculations and inferences. Conversely, introvert students met all four indicators of mathematical critical thinking skills and exhibited greater meticulousness, enabling them to answer questions in accordance with their intended purpose. Critical thinking, literacy, and numeracy are three interrelated and inseparable skills. Therefore, students with strong critical thinking skills are more likely to possess proficient literacy and numeracy skills as well.

2023-12-11T14:06:45+07:00

Discusses the challenges faced by the education system in Indonesia as it adapts to the changes brought about by the development of technology and communication. The emergence of Industry 5.0 poses a significant challenge, forcing educational institutions to implement remote learning processes. Terms such as blended learning, hybrid learning, flip-classroom, and others have become ways to integrate online and offline teaching and learning activities. This integration presents new challenges in terms of effectiveness, efficiency, and engagement in designing learning that combines various media and strategies.

According to Prof. Punaji (2020) in his book on learning design, learning design is a process that involves planning the needs and objectives of learning, developing teaching media, and systematically implementing an effective and efficient learning system to achieve predetermined learning goals. Various factors, such as materials and activities, student characteristics, curriculum, experimentation, teaching methods and media, and learning evaluation, need to be considered in the development of learning design. Combining learning design with technology is expected to make learning more effective and efficient, leading to optimal results.
