PENGEMBANGAN PERANGKAT PENILAIAN DIRI (SELF ASSESSMENT) PESERTA DIDIK MELALUI PENERAPAN MODEL PEMBELAJARAN LANGSUNG (Studi pada Materi Pokok Kelarutan dan Hasil Kali Kelarutan)
The study was a development research, which aimed at developing self assessment instrument of students through the implementation of direct instruction model on solubility and solubility product subject material which fulfilled the criteria of valid and practical. The development process referred to 4-D development model which consisted of four phases, namely: (1) definition phase; which pre and post analysis were conducted students analysis, material analysis, task analysis, and formulation of learning objectives, (2) design phased; which created the instrument developed included media selection, format selection, and prior design, (3) development phased; which conducted validation by the experts and conducted limited tryouts toward the instrument, and (4) dissemination phase; which conducted socialization to Chemistry teachers. The final products of the study were student’s self assessment book and student’s workbook. The instrument developed was already validated and revised by the experts and has fulfilled the criteria of valid and feasible to be used. The field test was conducted at SMAN 11 Makassar which covered the implementation of self assessment instrument and the result indicated that the category was mostly implemented. Thus, based on the quality of the instrument, the study indicated that the self assessment instrument of students by implementing direct instruction model on solubility and solubility product subject material has fulfilled the criteria of valid and practical.
