Abstract

To face the challenges of Indonesian education in the 21st century, the requirements for abilities are crucial, but the facts show that students are less able to use and adapt their abilities with insights aligned with the identity of the Indonesian nation. For this reason, researchers developed an E-Mowara: Interactive Emodule with an Archipelagic Outlook. This study aimed to develop the E-Mowara electronic module and find out students' responses after using the developed media. The target of this study was class VIII junior high school students with number pattern material. This development research uses a design research type of development study. The data collection technique in this study used a questionnaire with data processing techniques analyzed using percentage data analysis techniques. This is based on the validation results in terms of the material average of 84.35% with the appropriate criteria, and in terms of media, an average of 85.90% with the appropriate criteria. Students' responses to E-Mowara were quite good, with a percentage of 92.5%. Based on this result, the E-Mowara Electronic Module is known as valid, easy to use, and effective in developing computational thinking skills with insights that are in harmony with the identity of the Indonesian nation.

Abstract

Rationalism value is closely related to mathematics because it is based on reason and knowledge. The results of rationalism values develop students' skills in terms of reasoning, expressing and defending their opinions, interpreting data obtained from experiences and attempting to make predictions. Therefore, this study aims to describe student rationalism values in linear program problem-based learning. The research subjects were determined purposively based on the result of summative assessment, teacher recommendation, the diversity of answers, and the willingness to be involved in the research. The selected subject was three students of class X SMA in Indralaya. The data were collected using tests and interviews, which were analyzed descriptively. The Problem-based Learning Model can bring out Rationalism Values in Linear Program material. Students can develop indicators, investigate the truth, and conclude. The indicators that appear most frequently are investigating the truth. Difficulties often predominantly arise when translating problems into mathematical models. The cause of students experiencing errors in concluding is due to errors in understanding mathematical concepts in the form of inequality signs where students mistakenly differentiate between the inequalities "less than" and "less than equal to", one of the reasons for this is because they have not mastered the prerequisite material such as linear inequalities in one variable or two variables.

Abstract

Students always experience difficulties in learning ordinary differential equations. The existence of teaching materials that can make students learn actively independently, encourage curiosity, and improve their mathematical abilities is needed. This research aims to produce teaching materials for ordinary differential equations that contain the steps of Wankat and Oreovocz Problem Solving Strategies (I can explore, plan, do it, check, and generalize). This research was conducted in the odd semester of 2023/2024 at the FKIP UIR Mathematics Education Study Program by involving 5th-semester students as product test subjects. Development research was used in this study, using a 4D design (define, design, development, and dissemination). The research instrument consisted of validation sheets and the practicality of teaching materials. Validation of teaching materials was carried out by 3 validators, while the practicality trial of teaching materials was carried out by using teaching materials in the learning process. Data obtained from validators and students will be analyzed descriptively quantitatively, while information related to suggestions, input, and student responses will be analyzed descriptively qualitatively. The teaching materials developed received an assessment with a score of 0.9 or with very valid criteria. While 95% or almost all responses stated that the teaching materials used were very practical, it was still found that students could not learn quickly in completing the tasks.

Abstract

According to research, PISA, and national exams, pupils' numeracy literacy is generally low; teachers frequently utilize less participatory and irrelevant real-life teaching methods. Learning can be made more engaging by integrating technology into it, one example being the application of artificial intelligence (AI). This study aims to examine the validity and usefulness of student worksheets created using artificial intelligence to improve numeracy literacy abilities in the area of linear inequality of one variable. This is a preliminary and formative evaluation study. Product preparation and design were completed at the preliminary stage. Furthermore, formative evaluation stages include expert review, one-on-one, small group, and field tests. The material used is linear inequality in one variable, and the questions are related to numeracy literacy metrics. Questionnaires and interviews were employed to obtain the data. The questionnaire consists of both validity and practicality questionnaires. Validity data is derived from expert comments and suggestions. Questionnaires and interviews are used to collect practical data. The validity and practicality of data were qualitatively assessed by changing the worksheets in response to the validator and student comments and suggestions. The study's findings revealed that worksheets using AI were deemed valid at the expert review stage and very practical based on the results of the practicality questionnaire and interviews at the one-on-one, small group, and field testing phases. AI-powered worksheets can be utilized more widely to promote learning in class and individually. Schools might include AI technology in their learning strategies to increase numeracy literacy.

Abstract

This study addresses the critical issue of insufficient spatial thinking abilities among students, which significantly affects their performance in higher-order thinking skills (HOTS) tasks, particularly in trigonometry. Focusing on 11th-grade students in Tanjungpinang, Indonesia, the research investigates how spatial thinking influences the ability to solve trigonometric comparison problems. Employing a mixed-method approach, the study integrates quantitative data from the Higher-Order Thinking Skills in Trigonometric Comparisons Assessment (HOTS-TCA) with qualitative insights from post-test interviews. Rasch Model Analysis evaluates the quality of an assessment instrument by providing measures of respondent abilities and item difficulties, fit statistics to ensure model alignment, reliability, and separation indices for consistency, a Wright Map for visualizing the relationship between skills and difficulties, and checks for unidimensionality and potential item bias to ensure fairness and validity. The Rasch analysis further confirms the reliability and validity of the HOTS-TCA instrument, highlighting its effectiveness in measuring spatial thinking across varying ability levels. The study finds that students with high spatial ability excel in visualizing geometric relationships but struggle with complex three-dimensional tasks. In contrast, medium-ability students have difficulties with mental manipulation and real-world applications, and low-ability students face significant challenges in basic visualization and interpreting geometric structures, leading to frequent misconceptions.

Abstract

This research is motivated by students' low mathematical reasoning ability due to conventional teaching methods and the lack of learning resources that support students' reasoning skills. Local wisdom-based student worksheets were developed using the Realistic Mathematics Education approach to address this issue. Local wisdom from Tanjungpinang, Riau Islands, such as Otak-otak and Batik Gonggong, was used as the context for learning Systems of Linear Equations in Two Variables. The research method used is Research and Development (R&D) with a 4D development model (define, design, develop, disseminate). The instruments for assessing validity and practicality were expert validation questionnaires and student response questionnaires using a Likert scale. The effectiveness instrument used was a set of four essay questions. Data obtained on the Likert scale were analyzed using the Method of Successive Interval (MSI). Validation results showed that the student worksheets were categorized as valid, with an average expert validation percentage of 76.2%. Practicality tests yielded an average percentage of 77.59% (small group) and 67% (field test), both categorized as practical. The effectiveness test results showed an average score of 79.8 in the high category, and the mathematical reasoning ability test was deemed effective, with a classical mastery level of 90%. This study highlights the effectiveness of local wisdom-based worksheets using the Realistic Mathematics Education approach to facilitate students' mathematical reasoning skills and encourages teachers to integrate local wisdom into student worksheets.

Abstract

The 21st century demands educational approaches that align with technological advancements and societal needs. STEAM (Science, Technology, Engineering, Arts, and Mathematics) integrates multiple disciplines to foster critical thinking, creativity, communication, and collaboration in solving real-world problems. This study aims to explore ninth-grade students' perceptions of STEAM-based mathematics learning at SMP Negeri 13 Palembang. A mixed-method approach was employed, involving 94 students aged 13–15 years through questionnaires and unstructured interviews. Quantitative data were analyzed using Likert scale scoring, while qualitative data were assessed descriptively. Results indicate that students generally understand the concept of STEAM but lack clarity regarding its learning models, benefits, and assessment techniques. Most students (70.68%) perceived STEAM-based mathematics learning positively, finding it engaging, beneficial for understanding and retaining concepts, and motivating for further learning. Additionally, integrating technology and arts in mathematics increased student interest and participation. The study concludes that STEAM-based learning can enhance the effectiveness of mathematics education by creating a more interactive and meaningful experience for students. This approach equips students with essential 21st-century skills, making it a relevant strategy for future educational practices. Further studies are recommended to assess its long-term impact on student achievement and engagement.
