Abstract

Tujuan dari penelitian ini adalah untuk memastikan kesalahpahaman yang umum terjadi di kalangan siswa dengan kemampuan berpikir kritis, serta alasan yang mendasari terjadinya kesalahpahaman tersebut. Penelitian ini dilakukan di dalam lingkungan pendidikan. Penelitian ini menggunakan metodologi penelitian kualitatif dan menggunakan penelitian studi kasus, serta prosedur analisis data seperti reduksi data, penyajian data, dan penarikan kesimpulan. Temuan penelitian ini menunjukkan bahwa siswa yang memiliki kemampuan berpikir kritis yang terbatas selama mengerjakan tes menunjukkan miskonsepsi, khususnya di bidang klasifikasi, korelasi, dan teori. Selain itu, kesalahpahaman tersebut dipengaruhi oleh faktor internal dan eksternal. Siswa yang menunjukkan kemampuan berpikir kritis tingkat menengah selama mengerjakan tes mungkin mengalami kesalahpahaman, misalnya dalam bidang kategorisasi, korelasi, dan teori. Kesalahpahaman ini terutama disebabkan oleh pengaruh eksternal sebagai alasan yang mendasarinya. Siswa yang memiliki kemampuan berpikir kritis tingkat lanjut pada saat mengerjakan tes tidak mudah salah paham, melainkan salah perhitungan. Terjadinya miskonsepsi sebagian besar dipengaruhi oleh variabel eksternal. Kata Kunci: Miskonsepsi, kemampuan berpikir kritis, faktor penyebab miskonsepsi

Abstract

The research method used in this research is descriptive qualitative research with the aim of the research being to describe the mathematical communication profiles of blind students. This research was conducted at SLB Negeri Rasau Jaya which is located at Education Street No. 2, Desa Rasau Jaya Satu, Rasau Jaya District, Kubu Raya Regency, West Kalimantan Province, using the K13 curriculum. This study will describe the mathematical communication of SLBN Rasau Jaya students in the Cartesian coordinate material seen from aspects (1) The ability of students to give answers using everyday language in explaining ideas, situations and mathematical relations, orally or in writing with real objects, pictures, graphics and algebra. (Aspects of Written text); (2) Students' ability to connect real objects, pictures, and diagrams into mathematical ideas. (Drawing Aspects); (3) Students' ability to express everyday events in language or mathematical symbols. (Aspects of Mathematical Expression). In this study, the subjects of the study were all students of class VIII SLB Negei Rasau Jaya, which consisted of three students with low vision criteria. The data collection tools used in the research were observation sheets, interviews, and written tests. The mathematical communication skills of blind students have good abilities in the aspect of drawing. While the writing aspect was not fulfilled properly and the mathematical expression aspect did not meet the indicators at all.

Abstract

This study aims to produce interactive video learning media in mathematics learning to improve students' mathematical understanding that is valid, practical and effective. This research is a development research where the research procedure uses a 4D design, namely (Define, Design, Development, and Dissemination) but this research only reaches the Development stage due to limited time, costs and research subjects. The subjects in this study were 26 class X students of SMAN 1 Nanga Tayap. The instrument used by the researcher was a validation sheet to see the validity of interactive video media, a response questionnaire was used to see the practicality of interactive video media and a pilot test was used to see the practicality of interactive video media in improving students' mathematical understanding abilities. Based on the validation of the three validators on learning interactive video media, it can be declared valid with an average index percentage of 79.69% with valid criteria. Material expert validation was declared valid with an average index percentage of 78.88% with valid criteria. Meanwhile, media expert validation was declared valid with an average percentage index of 79.28% with valid criteria. The level of practicality with an average percentage of teacher responses is 80%, with very valid criteria and an average percentage of student responses is 82.66% with very practical criteria. From the results of completing the teacher and student response questionnaire, interactive video learning media for students' mathematical understanding can be stated to be very practical for students. The level of effectiveness of students after using interactive video learning media on mathematical understanding abilities is 80.76% with very effective criteria.

Abstract

Abstract: This study aimed to develop a Wordwall-assisted test instrument to measure students’ mathematical creative thinking skills on the topic of relations and functions for eighth-grade students at SMP Negeri 2 Sintang, and to determine its validity, practicality, and effectiveness. The research employed a Research and Development (R&D) method using a 3D development model consisting of the define, design, and development stages. The research subjects included three material experts, three media experts, and 28 students of class VIII E at SMP Negeri 2 Sintang in the 2025/2026 academic year. Data were collected through validation sheets, teacher and student response questionnaires, and a mathematical creative thinking skills test. Data analysis was conducted to determine the validity, practicality, and effectiveness of the developed product. The results showed that the developed Wordwall-assisted test instrument met the criteria of being highly valid, highly practical, and effective. The validity level, based on assessments by material and media experts, obtained an average percentage of 87.95%, categorized as highly valid. The practicality level, based on teacher and student response questionnaires, obtained an average percentage of 88.86%, categorized as highly practical. The effectiveness level was determined from students’ post-test results, where 20 out of 28 students achieved learning mastery, resulting in a mastery percentage of 71.43%, which falls into the effective category. Therefore, the Wordwall-assisted test instrument on the topic of relations and functions is feasible to be used as an evaluation tool for measuring the mathematical creative thinking skills of eighth-grade students at SMP Negeri 2 Sintang. Keywords: Test Instrument, Wordwall, Mathematical Creative Thinking Skills, Relations and Functions.
