Penelitian ini terfokus pada analisis Pedagogical Content Knowledge (PCK) calon guru kimia menggunakan CoRe (Content Representation) Framework dan strategi metakognitif  pada mata kuliah Telaah Kurikulum Kimia.  PCK merupakan representasi gabungan antara isi materi pelajaran dan pedagogik yang dimilik oleh guru sehingga siswa tertarik dan mudah untuk memahami suatu materi (Shulman, 1987). Oleh karena itu, CoRe framework dan strategi metakognitif pada penelitian ini digunakan untuk mengembangkan penguasaan konsep kimia dan cara menyampaikan konsep tersebut. Penelitian ini menggunakan pendekatan kualitatif, dengan studi interpretif kualitatif hingga menghasilkan profil PCK calon-calon guru kimia terkait dengan penguasaan konsep-konsep kimia. Data diperoleh dari rubrik PCK, MAIT (Metacogitive Awareness Inventory for Teachers), wawancara, observasi, nilai tes konsep, dan kertas refleksi. Hasil penelitian ini menunjukkan bahwa tingkat PCK calon-calon guru kimia tergolong tinggi. Terlihat bahwa Content Knowledge (CK) yang mereka miliki sedikit lebih tinggi daripada Pedagogical Knowledge (PK). Hasil MAIT (Metacogitive Awareness Inventory for Teachers) juga menunjukkan bahwa calon-calon guru tersebut memiliki kesadaran metakognitif yang sangat tinggi sehingga mereka mengetahui kelemahan dan kekuatannya sendiri dalam mengajar.   Kata kunci: Pedagogical Content Knowledge, Content Representation, Strategi Metakognitif, Telaah Kurikulum Kimia

AbstrakPengobatan secara biokimia adalah sistem pengobatan secara alamiah yaitu sistem pengobatan sel-sel tubuh dengan menggunakan garam-garam anorganik yang terdapat dalam darah dan jaringan. Garam anorganik ini atau dapat menyembuhkan berbagai macam penyakit walaupun garam ini dalam tubuh terdapat dalam jumlah yang sangat kecil, tetapi sangat diperlukan sebagai bahan aktif untuk membangun bejuta-juta sel. Bila bahan ini tidak mencukupi dibawa oleh darah mengakibatkan gangguan keseimbangan tubuh yang ditunjukkan dengan gejalagejala atau berbagai keluhan-keluhan rasa sakit yang disebut dengan penyakit. Pada sistem pengobatan secara biokimia ini hanya memerlukan dua belas macam garam-garam anorganik yang meyerupai garam-garam anoganik yang terdapat dalam tubuh manusia. Bila kekurangan salah satu garam-garam ini akan menimbulkan bergagai gangguan kesehatan. AbstractA biochemical treatment is a natural treatment system, such as body cells treatment system use inorganik salt existed in human blood and tissues. The inorganic salt can heal all kind diseases, even though these salt existed in smaller amount inside body. These salt are required as active substances to build a million cells. When these substances are inadequate and transported by blood, the disturbance of body balance will occur. These condition are indicated by symptoms and various pains which are called diseases. On the biochemical treatment needs only twelve inorganic salts existed inside body. When a human lacks one of these salt, the various health disturbances will take place.
