Sa’dijah, Cholis. 2005. Development of Constructivist Learning Model for Student Mathematics to Junior high. Dissertation, Mathematics Education Studies Program, Graduate Program, State University of Surabaya. Advisors: Prof. Drs. H. Herman., M.Ed.
This research has the objective to get the results that the reference model of mathematics learning I constructivism to junior valid, practical, and effective. This research focuses on developing mathematics models of the development of learning models that reference to constructivism (PMBK) according to the purpose of this research. Product development in this research is PMBK model and its learning tools and instrument. Learning devices, namely: Learning Plan(RP) and math activity sheet for students(LKSM). Includes test sheets each end of learning activities. PMBK model components in this study is syntax, socials system, principles of reaction, support system, as well as instructional impact, and impact accompaniment. PMBK model development is based on a general model of problem-solving education by Tjeerd Plomp which consists of five phases, namely: the initial investigation phase, the design phase, the realization phase, phase of testing, evaluation, revision and implementation phase.
Results PMBK model development in this study has systematically (steps of learning), which consists of three introductory activities, core activities, and activities cover. Core activities consist of 4 phases, namely the awareness phase, operational phase, the reflective phase and approval phase of preparation. The result of model development criteria of validity, practicality, and effectiveness.
