Tujuan dalam penelitian ini adalah untuk mengetahui pengaruh model problem based learning (PBL) terhadap kemampuan pemecahan masalah matematik ditinjau berdasarkan gaya kognitifnya.. Metode yang digunakan eksperimen dengan rancangan treatment by level 2 x 2.Pengambilan sampel menggunakan teknik cluster random sampling. Penelitian dilakukan di SMA Negeri 4 dengan sampel sebanyak 40 orang yang dipilih secara acak. Instrumen yang digunakan soal tes gaya kognitif dan kemampuan pemecahan masalah matematik. Analisis data yang digunakan normalitas,homogeniitas, ANAVA dua jalur dan uji Tukey.. Hasil penelitian menunjukan: (1) Kemampuan pemecahan masalah matematik dikelas Problem Based Learning lebih tinggi dibandingkan dengan kelas pembelajaran langsung. (2) Ada keterkaitan atau interaksi antara model pembelajaran Problem Based learning dengan gaya kognitif terhadap kemampuan pemecahan masalah matematik siswa. (3) Kemampuan pemecahan masalah matematik siswa antara siswa yang memiliki gaya kognitif FI dan mengikuti model pembelajaran Problem Based Learning lebih tinggi dari siswa yang mengikuti model pembelajaran langsung. (4) Kemampuan pemecahan masalah matematik siswa antara siswa yang memiliki gaya kognitif FD dan mengikuti dengan Problem Based Learning lebih tinggi dari siswa yang mengikuti pembelajaran langsung
Kata Kunci: PBL, Gaya Kognitif, field independent, field dependent, pemecahan masalah
This research aimed to analyze and describe the approach that was used to introduce the concept of fractions in elementary school mathematics textbooks. There were six 3rd grade of elementary school mathematics textbooks that represented two curriculums which were the 2006 curriculum and the 2013 curriculum that were included in the analysis. Vertical analysis of textbook research was conducted to focus on how the concept of fractions was introduced in the textbooks for each curriculum. The results of the research indicated that all the books included in the analysis only used one construct of fractions, which was as part-whole, to introduce fractions. This could cause the students to be narrow-minded about fractions and its implementations for further materials and in everyday life. Further discussion about the results can be seen in this article.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
