Designing and Authenticating a Problem Based Curriculum model in Elementary Mathematics

 The main purpose of the study is to design a valid model for the problem-oriented curriculum in elementary mathematics. The research approach is quantitative. In designing the model, which was done by structural-interpretive modeling method, 19 specialists of curriculum planning and mathematical education of Arak city participated. To determine the validity, with the method of partial least squares, the designed model in the form of a researcher-made questionnaire was provided to 355 specialists by random sampling method. By identifying the components of objectives in three levels of cognition, attitude, skill and curriculum content, method and evaluation of the problem-oriented curriculum model were designed and validated.. Findings showed that the characteristics of objectives in level "cognitive" and "attitude" are considered as the underlying components of the problem-oriented curriculum model in mathematics and affect the characteristics of objectives at the skill level. Skills characteristics also affect curriculum content characteristics, method, and evaluation.
