Abstract

Penelitian ini merupakan penelitian kualitatif. Subjek penelitian ini adalah siswa kelas VIII-1 SMP Negeri 29 Medan. Teknik pengumpulan data yang digunakan adalah angket, tes, wawancara dan dokumentasi... Wawancara dilakukan terhadap 6 orang siswa yang terdiri dari 2 siswa dari setiap gaya belajar. Hasil penelitian ini adalah: Siswa dari ketiga gaya belajar cenderung dapat melaksanakan indikator kemampuan pemahaman konsep. Kecuali mengklasifikasikan objek berupa pola bilangan pada gaya belajar visual auditorial. Siswa visual mampu memenuhi indikator menerapkan hubungan antara konsep dan prosedur. Tetapi mengalami kesulitan dalam menyatakan kembali konsep dan menyajikan konsep dalam representasi berupa narasi (menggunakan unsur verbal). Siswa auditorial mampu memenuhi indikator menyatakan kembali konsep dan menyajikan konsep dalam representasi berupa narasi. Tetapi mengalami kesulitan dalam menerapkan hubungan antara konsep dan prosedur di luar dari konsep yang biasa mereka temukan, diikuti dengan indikator menerapkan konsep secara algoritma juga melaksanakan perhitungan secara tepat. Siswa kinestetik mampu memenuhi indikator menerapkan hubungan antara konsep dan prosedur diikuti dengan indikator menerapkan konsep secara algoritma. Diikuti dengan mengklasifikasi objek sesuai konsepnya. Tetapi mengalami kesulitan dalam indikator indikator yang menggunakan unsur verbal.

Abstract

This research aims to produce the development of TIMSS equivalent questions to measure students' mathematical reasoning abilities in geometry content that are valid, practical and effective and to describe students' mathematical reasoning abilities in solving TIMSS equivalent questions developed in geometry content. This research is a formative evaluation type of development research with two stages, namely the preliminary stage (preparation stage) and the prototyping stage using a formative evaluation flow consisting of self evaluation, prototyping (expert reviews, one-to-one and small group), and field test. The instruments used were a description test with 7 questions, a response questionnaire from students, teachers and lecturers. The results of this research indicate that TIMSS-equivalent questions have been successfully developed to measure students' mathematical reasoning abilities in quality geometry content as seen from: (1) Validation by experts was declared valid because the three validators stated "The questions can be used with revisions" and validity calculations used Microsoft Excel declared valid.; (2) The practicality of the TIMSS equivalent questions developed in geometry content was categorized as sufficient and the average positive response from students was 89.2%; (3) The effectiveness of developing TIMSS equivalent questions to measure students' mathematical reasoning abilities in geometry content is considered "effective" with an average of 82%; (4) The mathematical reasoning ability of class VIII students at SMP Negeri 11 Medan in developing TIMSS equivalent questions was obtained by 12 students being poor, 16 students being adequate, 8 students being good and 0 students being very good in the sufficient category.
