ABSTRAKTujuan penelitian ini adalah untuk mengetahui profil motivasi belajar Mahasiswa Calon Guru Kimia (MCGK) tingkat I sampai dengan tingkat IV. Selain itu, juga dikaji korelasi antara motivasi dengan model mental kimia sekolah. Penelitian dilakukan menggunakan metode kuantitatif non eksperimen, dengan desain survei lintas-bagian (cross-sectional survey) dan melibatkan 124 mahasiswa calon guru kimia di jurusan Pendidikan Kimia pada salah satu Universitas di Bandung. Data dikumpulkan melalui Kuesioner Motivasi Belajar Kimia (KMBK) dan Tes Diagnostik Model Mental Kimia Sekolah (TDMKS). Hasil analisis deskriptif menunjukkan motivasi belajar MCGK pada kategori rendah untuk tingkat I (M=3,04; SD=0,24) dan kategori sedang untuk tingkat II (M=3,56; SD=0,20), tingkat III (M=3,78; SD=0,26), dan tingkat IV (M=3,89; SD=0,25). Hasil uji Kruskal Wallis menunjukkan adanya perbedaan secara signifikan pada sebagian besar jenis motivasi belajar MCGK berdasarkan tingkat kelas, kecuali jenis target prestasi. Motivasi belajar MCGK berkorelasi pada tingkat sedang dengan model mental kimia sekolah (r=0,399; p<0,01). Kata kunci : motivasi belajar, model mental, kimia sekolah, tes diagnostik ABSTRACTThe aim of this research was to know the learning motivation profile of the Pre-service Chemistry Teacher (PCT) from the first to the fourth grade. Besides that, the correlation between motivation and school chemistry mental model was also examined. The research was conducted using nonexperiment quantitative model, with the cross-sectional survey design and involved 124 PCT in Chemistry Education Department in one of universities in Bandung. The data was collected from the Questionnaire of Motivation toward Chemistry Learning (QMCL) and the Diagnostic Test of School Chemistry Mental Models (DTSCM). The result of the descriptive analysis showed that the learning motivation of PCT was in the low category for the first grade (M=3,04; SD=0,24) and the middle category for the second (M=3,56; SD=0,20), the third (M=3,78; SD=0,26), and the fourth grade (M=3,89; SD=0,25). The result of Kruskal Wallis Test showed there was a significant difference in most of the learning motivations of PCT according to grades, except for achievement goals. The learning motivaton of PCT moderately correlated with school chemistry mental model (r=0,399; p<0,01).Keywords : learning motivation, mental model, school chemistry, diagnostic test PENDAHULUANMotivasi diturunkan dari kata kerja bahasa Latin 'movere' yang berhubungan dengan gagasan logis untuk membuat seseorang terus bergerak, terus beraktivitas, dan membantu menyelesaikan tugas-tugas (Schunk, et al., 2010;Biehler & Snowman, 1997). Motivasi telah dimaknai dengan berbagai cara, baik sebagai kekuatan internal, perilaku bertahan, respon singkat terhadap stimulus, maupun serangkaian kepercayaan dan pengaruh. Definisi motivasi yang dianggap mewakili banyak pendapat peneliti adalah proses yang melibatkan dan mempertahankan aktivitas untuk mencapai tujuan (Schunk, et al., 2010). Schunk, et al. (2010) mengelompokkan...

This study aims to develop intertextual-based learning strategies using visualization models to improve students' spatial abilities on molecular geometry concepts. In this study using the method of Research and Development (RD). The research subjects used were 20 high school 10th grade students. In this study the instrument used was in the form of an intertextual-based learning strategy validation sheet with visualization models, 3D visualization software, and spatial ability tests. Spatial ability consists of three indicators to be evaluated, namely spatial relations, spatial orientation, and spatial visualization. The results of intertextual-based learning strategy research with developed visualization models can improve spatial ability. Students can understand molecular geometry from the concept of VSEPR theory and valence bond theory. Results pre-test student on the spatial relations (26.67%), spatial orientation (10.10%), and spatial visualization (7.41%). After being tested intertextual-based learning strategies with visualization models of students' post-test results on the spatial relations (58.33%), spatial orientation (50.00%), and spatial visualization (27.78%).

Prospective teacher's metacognition knowledge such as declarative knowledge, procedural knowledge, and conditional knowledge is becoming crucial in the development of an efficient learning design. This lead to the urgency in measuring the level of metacognitive knowledge of prospective teachers. Currently, rubric to measure prospective teacher's metacognition knowledge in designing learning instruction is very limited. Therefore, this study aims to develop a rubric to assess metacognition knowledge in designing learning instruction. The Research and development methods are employed with the development design model including the preliminary study phase, development study phase, and evaluation stage. The rubric prototype resulted includes declarative, procedural and conditional knowledge in designing learning instruction on GPA aspects, learning objectives, learning materials, learning strategies, learning steps, learning media, learning resources, and learning outcomes assessment.

The study aims to design an intertextual learning strategy with Predict-observe-explain (POE) to develop students' science process skills. The research method is Research and Development (R&D) consist of material analysis, developing indicators of science process skills, and developing learning designs. The learning design was validated by five experts. Based on experts’ suggestion, intertextual-based learning activities involving three levels of chemical representation with POE learning steps to build the concept of the effect of the nature of the reactant and catalyst on reaction rates and develop students' science process skills. The strategy consists of five phenomena which are followed by three experiments and two videos as observation tools for the student. The explanation stages are guided by sets of guiding questions that involve multi-representation levels in that explanation. The product of this research is expected to be used as an alternative learning strategy that can be used by teachers to minimize the possibility of misconceptions that occur, increase mastery of concepts, and students' science process skills.
