Abstract


Issues examined in this study is whether learning by using multiple representations model (SiMaYang) more effective in build mental models than conventional learning? The design of this study is a pretest and posttest control group design. The research sample taken randomly by stratified random sampling technique to obtain the experimental and control classes. The results of the research show that (1) SiMaYang learning model more effective in building student mental models compared to learning model that has been used by basic chemistry lecturers. (2) Implementation of SiMaYang learning model was able to build student mental models in learning of stoikiormetry topic. (3) After the implementation of SiMaYang model, student mental models on the topic of stoichiometry formed by the categories of "good" and "very good", with the characteristics of "consensus" and "target". Findings indicated thatmacro-sumiglcro-symbolic teaching by used SiMaYang model could be enhancing student mental models and learning effectivity of chemical reactions. Implications for instruction are clearly addressed in the discussion and recommended that SiMaYang learning model can be used as an alternative model of effective and efficient learning in developing a high level of understanding.

Isu yang dianalisis pada penelitian ini adalah apakah belajar menggunakan model multipel representasi (disebut SiMaYang) lebih efektif dalam membangun mental model dari belajar secara konvensional? Desain penelitian ini adalah pretest dan posttest kelompok kontrol. Sampel penelitian diambil secara acak dengan teknik sampling acak bertingkat untuk mendapatkan kelas kontrol dan kelas eksperimen. Hasil penelitian menunjukkan bahwa (1) model pembelajaran SiMaYang lebih efektif dalam membangun model mental mahasiswa dibandingkan model pembelajaran yang telah digunakan dosen kimia dasar. (2) implementasi model pembelajaran SiMaYang dapat membangun model mental mahasiswa dalam belajar topik stoikiometri. (3) setelah implementasi model SiMaYang, model mental mahasiswa pada topik stoikiometri terbentuk pada kategori baik dan sangat baik, dengan karakteristik konsensus dan target. Temuan mengindikasikan bahwa pengajaran macro-sumiglcro-symbolic menggunakan model SiMaYang dapat meningkatkan model mental mahasiswa dan efektivitas reaksi kimia. Implikasi petunjuk secara jelas dibahas pada diskusi dan direkomendasikan bahwa model pembelajaran SiMaYang dapat digunakan sebagai alternatif model pembelajaran yang efektif dan efisien dalam mengembangkan tingkat pemahaman yang tinggi.
