Abstract

This study aims to develop an HTML5 Package-based E-Module on the material of Two-Variable Linear Equation System (SPLDV) which is valid and practical on, the results of the mathematical representation test of students solving SPLDV problems on 12 students obtained an average score of 75 in the good category. The research method used is Research and Development with a 4D development model, which includes the Define, Design, Develop, and Disseminate stages. Data collection techniques through media validation tests through media and material expert validation forms, mathematical representation tests, questionnaire distribution. Data analysis by calculating the percentage of media and material expert assessments, and calculating questionnaire responses and mathematical representation test scores. The results of the media expert review show that the validity of the e-module from the media and material aspects is very valid. The practicality test on a large scale shows a percentage of 78.91% which is classified as practical. Student responses to this module are very good. In addition, the test results for 12 students showed an average score of 75 for completing SPLDV questions, which is considered good. Overall, it was concluded that the developed HTML5 Package-based SPLDV e-Module met the criteria for validity, practicality, and effectiveness for use in learning.

Abstract

This study aims to determine the characteristics of student errors in solving geometry proof based on Newman's Theory. The research method used is a qualitative research method with a phenomenographic approach. This research was conducted to prevent students from repeating mistakes in advanced geometry courses. The types of errors based on Newman's Theory used in this study are: (1) reading errors in the representation of mathematical symbols; (2) comprehension errors of the proof problem; (3) transformation errors of the proof problem; (4) process skills errors of the proof problem; and (5) encoding errors. The subjects of this study were 15 students, and the instruments used were interview guidelines and documentation. The results of this study are reading errors in the representation of mathematical symbols with an average of 15.81%, with error characteristics that students do not write geometry symbols according to the rules. Comprehension errors of the proof problem with an average of 4.78%. Transformation errors of the proof problem with an average of 26.84%. Process skill errors of proof problems with an average of 29.04%. Encoding errors with an average of 23.53%.

Abstract

Tujuan dari penelitian ini adalah untuk menganalisis pengaruh self efficacy terhadap kemampuan penalaran matematika peserta didik khususnya pada indikator menyusun dan menyelidiki konjektur, mengembangkan atau mengevaluasi argumen, serta memberikan contoh penyangkal dalam materi pola bilangan. Penelitian ini menggunakan metode kuantitatif dengan pendekatan deskriptif kuantitatif dan korelasional. Subjek penelitian terdiri dari 30 peserta didik di SMPN daerah Lembang pada tahun ajaran 2024/2025. Data dikumpulkan melalui tes uraian yang terdiri dari tiga pertanyaan dalam penalaran matematika dan kuesioner dengan dua puluh pernyataan. Untuk memastikan sejauh mana self efficacy memengaruhi keterampilan penalaran matematika peserta didik, metode analisis data menggunakan analisis deskriptif dan analisis regresi linier sederhana. Berdasarkan uji hipotesis dengan taraf signifikan 5% menunjukkan bahwa self efficacy memiliki arah hubungan positif tetapi tidak signifikan terhadap kemampuan penalaran matematika (Sig. = 0,177; R = 0,064). Artinya, self efficacy hanya memberikan kontribusi sebesar 6,4% terhadap kemampuan penalaran matematika peserta didik. Hasil temuan ini mengindikasikan bahwa faktor lain di luar self efficacy lebih dominan dalam memengaruhi kemampuan penalaran matematis peserta didik.
