Hipotenusa: Journal of Research Mathematics Education (HJRME)
ISSN : 26210630     EISSN : 2723486X     DOI : 1036269
Core Subject : Education,
Hipotenusa Journal of Research Mathematics Education (HJRME) is a peer-refereed open-access international journal which has been established for the dissemination of state-of-the-art knowledge in the field of mathematics education. This journal is founded under Department of Mathematics Education FKIP Universitas Muhammadiyah Lampung. Starting from 2020, HJRME would be published two times in a year (February & August). All submitted manuscripts will be initially reviewed by editors and are then evaluated by a minimum of two National Reviewers through the double-blind review process. This is to ensure the quality of the published manuscripts in the journal.

Abstract

This study was based on the low learning outcomes of students at SMP Negeri 4 Gadingrejo, where only 32 out of 126 students achieved the Learning Objective Achievement Criteria (KKTP). The research method used was quantitative with an experimental design, involving two groups: the experimental class (AI-based CTL) and the control class (Project Based Learning). The instrument used was a learning outcome test consisting of 5 essay questions that had been tested for validity and reliability. Data were analyzed to measure the differences in learning outcomes between the two groups. The results showed a significant difference between the average learning outcomes of students in the experimental class and those in the control class. The average learning outcomes of students who used the AI-based CTL model were higher than those who used the PjBL model. Based on the t-test, the calculated t value was 5.13, which was greater than the t-table value of 2.00, thus the research hypothesis was accepted. The conclusion of this study is that the application of the AI-based CTL learning model is effective in improving students’ learning outcomes on SPLDV material, and it is therefore recommended to consider using this model in mathematics learning.

Abstract

This study aims to describe the implementation of the Lesson Study for Learning Community (LSLC) cycle within Project-Based Learning (PjBL) and to analyze its impact on student engagement and digital literacy. The low level of students’ ability to utilize technology for academic purposes and for developing the competencies of prospective educators constitutes the primary background of this research.A descriptive qualitative method with a descriptive-analytic approach was employed. The research subjects were third-semester students of the Tadris Mathematics Study Program at State Islamic University Sulthan Thaha Saifuddin Jambi. Data were collected through questionnaires and digital observation sheets administered via Google Forms, and product assessment rubrics in the form of English-based mathematics E-Student Worksheets (ESW). Data analysis was conducted through the stages of data reduction, data display, and inductive conclusion drawing.The results indicate that the implementation of the Plan–Do–See cycle within PjBL contributed positively to the learning process. The integration of digital technology, such as the use of the Canva platform in proposal preparation and project development, was proven effective in enhancing students’ digital literacy, particularly in searching for, evaluating, and critically creating digital learning content. Furthermore, collaboration within a learning community fostered reflective skills, critical thinking abilities, and teamwork in producing high-quality and relevant instructional products

Abstract

This study aims to explore the ethnomathematics found in traditional Jambi musical instruments, especially wooden kelintang musical instruments. This type of research is a descriptive qualitative research using an ethnographic approach (socio-cultural) with data sources obtained from observation, interview, and documentation methods. Data analysis in this study uses the Spradley model analysis in Lexy J. Maleong including domain analysis, taxonomy analysis, component analysis, theme analysis. To check the validity of the data, the author uses the triangulation technique. This research was conducted at the Mindulahin Studio in Jambi City. The results of the study can be concluded that: 1) The mathematical concepts found in wooden kelintang musical instruments include: Flat shapes in the form of rectangles, circles, and trapezoids. Space shapes in the form of blocks, cylinders, angles in the form of 90 °, relations and functions, and arithmetic. 2) Ethnomathematic activities in wooden kelintang include activities of calculating, measuring, determining locations, making designs, playing, and explaining. All these activities can be seen from how to make wooden kelintang, the shape of the wooden kelintang, and when playing the wooden kelintang.
