Statistics education research integrated with Islamic studies (A study of validity and practicality of textbook development)

2025-03-11T13:05:38+08:00

This research is based on the need for a textbook of educational research statistics that is suitable for use, while its availability has not been met. Therefore, this research is a development study with ADDIE design (analysis, design, development, implementation, and evaluation), which aims to develop and produce an Islamic integrated educational research statistics textbook that meets valid and practical criteria. The data in this study were collected using questionnaire techniques and validity and practicality questionnaire instruments. Development is first carried out before these two instruments are used to ensure their feasibility. The data that has been obtained is analyzed using the Aiken index formula related to the calculation of validity and percentage related to practicality. The results of this study can be summarized in two conclusions. First, the Islamic integrated educational research statistics textbook is at the "very valid" validity level. The Aiken index score is 0.9215. Second, the Islamic integrated educational research statistics textbook based on mathematical communication skills is at the "practical" level of practicality. The numerical validity value is 77.66%. The implication of the results of this study is the production of a textbook that is suitable for use and tested for its effectiveness in learning educational research statistics.

Developing problem-based learning worksheet of relations and functions topic to support students’ conceptual understanding

2025-03-11T12:57:53+08:00

This research is qualitative research with design research methods and a development research type aiming to produce valid and practical worksheets on relational and functional materials based on problem-based learning (PBL) to support students' conceptual understanding. The learning process is carried out in the classroom with learning activities, accompanied by a student's worksheet, which consists of 2 questions. The subjects of this study were students of class VIII 10 of SMP Negeri 8 Palembang, with 6 students as the focus of the research. There are 2 stages in this research, namely: (1) preliminary stage and (2) prototyping stage (formative evaluation), which is divided into 5 stages, namely (1) self-evaluation, (2) expert review, (3) one to one, (4) small group and (5) field test. This research was conducted based on the learning system in schools with data collection techniques, namely walkthroughs, tests, interviews, and questionnaires, to be collected and analyzed qualitatively to see the validity and practicality of the worksheet. The results of this study will show that the worksheet that has been made is valid, as seen from the results of the expert review and practical validation sheets obtained from the questionnaire results, with an average of 84.03%, which is included in the valid and practical categories. The developed worksheet also supports understanding PBL-based concepts (Problem-Based Learning) in solving problems given in relation and function material, which can be seen from the overall student test results.

Ethnomathematics in the rhythmic patterns of Bebano musical instruments of the Malay community of Riau Islands

2025-03-11T12:47:44+08:00

Bebano instrument is one of the traditional Malay musical instruments, a type of percussion or hit instrument. Most of the rhythm patterns in Malay music can be played with Bebano, namely langgam, zapin, inang, joget, and jogi rhythm patterns. This study aimed to determine the form of ethnomathematics in the rhythm patterns of Bebano musical instruments as mathematics learning materials. This study is qualitative research with an ethnographic approach. The research subjects were Penyengat Island art activists at Staman Malay Music. Data was collected by observation, interview, and documentation, with the main instrument being the researcher himself. Data analysis techniques included domain analysis, taxonomy, componential, and cultural themes. The study's results found the concept of mathematics contained in the rhythm patterns of Bebano musical instruments. In playing activities, mathematical material is found, namely variablizing and combination. While in the calculation activity, mathematical material is found, namely the form of fractional numbers.

Development of an interactive E-Module based on realistic mathematics education (RME) to enhance students' mathematical reasoning skills on parallel lines and angles

2025-03-11T12:38:43+08:00

This study aimed to develop an interactive e-module based on the RME approach, focusing on parallel lines and angles. The e-module was designed using a development studies approach with two main stages: preliminary and formative evaluation. These included self-evaluation, expert review, one-to-one trials, small group trials, and field tests. Data were collected through validation sheets, student response questionnaires, pretests, and posttests. The e-module was deemed valid and practical, with average validation scores from experts and students of 4.4 and 4.89, respectively. Furthermore, the effectiveness of the e-module was measured using T-Test and N-Gain analysis, which showed a significant improvement of 38% in students' mathematical reasoning skills. The findings demonstrate that the RME-based interactive e-module is an effective teaching tool for enhancing mathematical reasoning skills, particularly on parallel lines and angles. This e-module provides an alternative solution for teachers to facilitate interactive, context-based, and independent learning, aligning with the demands of 21st-century education. Future research could explore integrating virtual laboratories or GeoGebra software into the e-module and applying it to other mathematical topics, such as angles in polygons.

Exploration of high school students' sentiments and emotions towards mathematics: Linked to learning outcomes

2025-03-11T12:30:34+08:00

Mathematics research often focuses only on students' learning outcomes without considering their emotional aspects. This study aims to describe the tendency of students' sentiment toward mathematics in general and partially based on mathematics learning outcome groups, namely high, medium, and low. In addition, a mood analysis was conducted using Ekman's Basic Emotion classification. Data collection techniques are questionnaires and documentation. The questionnaire contains open questions about students' opinions on mathematics and closed to queries for student demographics. Documentation is done by collecting test scores from student grade books. This study used a descriptive method with data in the form of 72 comments from grade XI high school students in Bandung City, which were analyzed using the Orange Application Sentiment Analysis. The results of the study showed that (1) student sentiment was generally dominated by positive sentiment at 72.22%, (2) positive sentiment also dominated the groups of students with high, medium, and low learning outcomes, with a percentage of more than 68%, and (3) the results of the classification of emotions based on Ekman's Basic Emotion indicated that "joy" was the most dominant emotion, while "anger" had the lowest frequency of occurrence. This study provides new insights regarding students' emotional aspects in mathematics learning, which can be used to improve teaching strategies.
