Abstract

Penggambaran makroskopis, mikroskopis dan simbol dalam mata pelajaran kimia yang disebut sebagai triangle levels of representations dapat membuat persepsi siswa terhadap konsep menjadi berbeda-beda dan ada kemungkinan mengalami miskonsepsi atau kesalahan konsep. Visualisasi dapat memperjelas persepsi atau mental image siswa mengenai gambaran suatu konsep yang ada dalam pikirannya. Pada pembelajaran materi koloid selama ini disampaikan dengan analogi secara verbal, sehingga dapat menimbulkan persepsi siswa yang berbeda-beda terhadap suatu konsep. Diharapkan jika terdapat kesalahan persepsi (miskonsepsi) pada siswa, maka akan dapat dideteksi lebih awal dengan menggunakan mental image. Tujuan penelitian ini adalah untuk mengetahui persepsi siswa terhadap konsep-konsep dalam materi koloid dengan menggunakan mental image. Penelitian dilaksanakan di SMA Negeri 1 Tangerang pada bulan Mei-Juni 2013. Metode yang digunakan adalah metode deskriptif analisis. Sampel dalam penelitian ini adalah siswa kelas XI IPA 1 dan XI IPA 2. Hasil penelitian menunjukkan bahwa sebagian besar siswa masih mengalami miskonsepsi pada beberapa konsep pada materi koloid. Kata kunci: miskonsepsi, koloid, mental image

Abstract

Chemical materials that are full of concepts and need to be understood by students one of them is colloidal material. Based on observations made in some schools found 70% of chemistry teachers argued that colloidal material has characteristic as above, but the students are less interested in learning, this resulted in understanding the concept is not optimal. Thus required learning model that maximizes the potential of the brain both cognitive and emotional aspects. One of the learnings that optimize brain potency is Brain-Based Learning (BBL). The primary purpose of this research is to get information about the influence of learning model (BBL and TGT) and self-regulation to understanding the concept of student colloid. The subjects of the study were public senior high school students in Tidore, with a total of 60 students in class XI. Based on the result of analysis with ANAVA 2 lane, showed that (1) colloid concept of student colloid is better if taught with BBL than TGT, (2) There is interaction between learning model and self regulation to understanding student concept, (3) high self regulation is better if taught with BBL, because students who have high self-regulation have the motivation and independence in solving the challenge, (4) While understanding the concept of students with low self-regulation is better if taught with TGT, Due to the presence of heterogeneous groups within TGT supports students who have low self-tregulation to collaborate with their group members so that understanding of conceptual understanding can occur well. Based on the result, it can be concluded that there is an influence of BBL model and self-regulation to understanding student concept.
