Abstract

This study aims to develop a Problem Solving-based Student Worksheet (LKPD) to improve problem-solving ability in solving statistics word problems for seventh-grade students at SMP Negeri 17 Pontianak, and to determine its validity, practicality, and effectiveness. The study was motivated by students' low problem-solving ability in statistics word problems, resulting from conventional teaching methods and limited worksheets used in schools. This study employed the Research and Development (R&D) method with a simplified 4D model reduced to a 3D model consisting of define, design, and develop stages. The research subjects consisted of three expert validators (two material experts and two media experts), 24 seventh-grade B students for instrument try-out, and 28 seventh-grade G students for the product try-out. Data were collected through validation sheets, teacher and student response questionnaires, and a problem-solving ability test (posttest), then analyzed descriptively using percentage formulas. The results show that the developed worksheet achieved a validity level of 93.56% (material expert 90.47%; media expert 96.66%), categorized as very valid; a practicality level of 92.45% (teacher response 94%; student response 90.91%), categorized as very practical; and an effectiveness level of 75%, categorized as effective, as shown by 21 out of 28 students achieving mastery learning. Thus, the developed Problem Solving-based worksheet is feasible to be used as an alternative teaching material to improve students' problem-solving ability in mathematics word problems.

Abstract

Chintamani Dayak Keninjal ikat weaving is a local wisdom of the Dayak Keninjal community in Ribang Semalan, Melawi Regency, West Kalimantan, that has not previously been integrated into mathematics instruction. This study aimed to develop a Student Worksheet (LKPD) based on the local wisdom of Chintamani Dayak Keninjal ikat weaving for teaching probability to junior high school students. The study employed the 4-D development model (define, design, develop, and disseminate), limited to the development stage. The research subjects consisted of three validators (two mathematics education lecturers and one mathematics teacher), 30 eighth-grade students in a limited trial, and 32 eighth-grade students in a field trial at SMP Swasta Sungai Kehidupan. Data were collected through tests, questionnaires, and validation sheets. The material validation scores were 72.41%, 74.48%, and 76.55%, while the media validation scores were 65.92%, 80.74%, and 77.03%, all categorized as valid. The worksheet achieved a practicality score of 83.52% (very practical) based on teacher responses and 79.33% (practical) based on student responses. The posttest results showed that 87.5% of students achieved mastery learning, indicating that the worksheet was very effective. These findings indicate that the LKPD based on the local wisdom of Chintamani Dayak Keninjal ikat weaving is suitable for use as a contextual mathematics teaching resource for probability while introducing students to their local culture.

Abstract

This study aims to develop learning media based on Augmented Reality (AR) on the topic of three-dimensional geometry for grade VIII students at MTs Mujahidin Pontianak. The research method used is Research and Development (R&D) with the ADDIE model. The research subjects consisted of material experts, media experts, and grade VIII students of MTs Mujahidin Pontianak. Data collection techniques included indirect communication techniques in the form of validation sheets, teacher and student response questionnaires, and measurement techniques in the form of learning outcome tests. The results showed that the developed AR-based learning media was categorized as highly valid with a validation percentage of 94.25% from material experts and 91.28% from media experts. The practicality test results indicated a very practical category with 95% from teachers and 92.58% from students. In addition, the effectiveness test showed an effective category with a learning completeness percentage of 79.16%. Based on these results, the AR-based learning media on three-dimensional geometry is considered feasible as an alternative mathematics learning media.
