Abstract

Penelitian ini bertujuan untuk mengetahui kemampuan pemahaman konsep dan kemampuan komunikasi matematis peserta didik SMA di Pesawaran setelah diberi perlakuan pembelajaran Children Learning in Science (CLIS) berbantuan alat peraga edukatif. Metode penelitian ini menggunakan metode quasy experimental design. Subjek penelitian terdiri dari 152 peserta didik kelas XI SMAN 1 Negerikaton dengan 60 peserta didik sebagai sampel penelitian. Teknik analisis data menggunakan uji normalitas, uji homogenitas dengan uji hipotesis statistik yaitu menggunakan uji One-Way Multivariate Analysis of Variance (MANOVA). Dari data yang diperoleh nilai sig 0,00 ˂ 0,05 maka menunjukan nilai rata-rata bahwa terdapat pengaruh model pembelajaran CLIS berbantuan alat peraga edukatif terhadap kemampuan pemahaman konsep dan kemampuan komunikasi matematis dibandingkan model pembelajaran konvensional yang diterapkan oleh pendidik disekolah. Kesimpulannya adalah terdapat hasil yang positif terhadap model pembelajaran tersebut.

Abstract

This study aimed to determine the effect of the NHT (Numbered Head Together) cooperative learning model on mathematical problem-solving abilities in terms of students' mathematical prior knowledge. The researchers employed quasi-experimental research and collected the mathematical problem-solving data using a description test. At the same time, the researchers investigated students’ mathematical prior knowledge using the mid-semester examination (UTS) scores. The hypothesis was tested using the two-way ANOVA with unequal cells. The results showed that the NHT learning model provided better problem-solving skills than the direct learning model. The category of students' prior knowledge also affected their mathematical problem-solving abilities. Therefore, teachers should pay attention to the prior knowledge possessed by students so that an appropriate learning model can be selected.
