Abstract

The existence of a Student Worksheet (LKPD) is able to improve the ability to understand students' concepts. This research aims to develop LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the ability to understand concepts based on validity, practicality, and effectiveness in geometric transformation materials. The type of research used is research and development (R&D) with a 4D model, namely the defining stage, the design stage, the development stage, and the deployment stage. This study was conducted at SMP Negeri 1 Tegalrejo with a sample of 31 students in class IX B. The results showed that an LKPD based on ethnomathematics of batik motifs typical of Magelang was produced to increase understanding of the concept of geometric transformation that is valid or feasible in terms of the validity value of LKPD by material expert validators and teaching material expert validators, which is 86.31% with a very valid category. Judging from the practicality value of LKPD by the response of students, which is 89.61% with a very practical category. The results of the standard gain increased concept understanding ability were obtained by 5 low classification learners, 10 medium classification students, and 16 high classification students. Increasing understanding of the concept of geometric transformation using LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the effectiveness value of the pretest and posttest results calculated using the standard gain formula <g> , which is 0.62 with a moderate category, so that LKPD is said to be effective.

Abstract

As many as 7.03% of people with disabilities in Indonesia are deaf people. The problem for deaf students is the lack of mathematics learning resources during learning and the low mathematical communication skills of deaf students. The purpose of this study is to analyze the development of sign language learning videos to improve mathematical communication of deaf students of fractional material in terms of validity, practicality, and effectiveness. The method used is the R&D method with a 4D model. The results showed that the validity of the media resulted in a very valid category by sign language experts with a score of 85% and material experts with a score of 83% and categories valid by media experts with a score of 78.5%. The results of media practicality of 100% for teacher and student responses and learning implementation questionnaires are said to be very practical. The results of the control class pretest and the experiment resulted in a sig value. > 0.05, then the data is normal. Homogeneity test with (6,14) <  (19) on pretest questions and (4,68) <  (19) on posttest questions then homogeneous data. Student scores resulted in a difference in the average student learning outcomes between the experimental class and the control class indicated by the T test results with the sig value. (0.001) < 0.05. The average value of the N Gain of the experimental class is greater than that of the control class, which is 0.9721 with a high category. so that the media is said to be valid, practical, and effective.

Abstract

Deaf students have characteristics of learning mathematics that are highly dependent on visual channels due to limited linguistic and sensory access, so that abstract mathematics learning often becomes a challenge. The mismatch between these characteristics and teachers' delivery of material that is predominantly verbal or uses complex language structures results in less effective learning communication. This study aims to gain an in-depth understanding of the patterns and dynamics of interaction among deaf students during the application of the peer tutoring method in mathematics learning, particularly in flat geometry. The research used a qualitative approach with a case study design involving 16 deaf students at SLB-B YPPALB Magelang City from elementary to high school levels, divided into four heterogeneous groups based on the level of hearing impairment, additional disabilities, and peer tutor roles. Data were collected through structured classroom observation, learning documentation, and semi-structured interviews, then analyzed through data reduction, data presentation, and conclusion drawing stages. The results showed that interactions between students through peer tutors were more intensive and effective than interactions between students and teachers. These findings are in line with Vygotsky's Social Constructivism theory, which emphasizes the role of social interaction and peer scaffolding in learning. Peer tutors function as linguistic and social mediators through sign language, gestures, and concrete representations, thereby facilitating the understanding of mathematical concepts. The dynamics of interaction are influenced by the degree of hearing loss, additional disabilities, and the communication skills of peer tutors. These findings recommend that mathematics learning for deaf students be strategically designed based on peer tutoring to improve interaction, participation, and conceptual understanding.
