Delaying Instruction Improves Mathematics Problem Solving: A Classroom Study
Engaging learners in exploratory problem-solving activities prior to receiving instruction (i.e., explore-instruct approach) has been endorsed as an effective learning approach. However, it remains unclear whether this approach is feasible for elementary-school children in a classroom context. In two experiments, second-graders solved mathematical equivalence problems either before or after rec...
متن کاملDeveloping a bi-objective optimization model for solving the availability allocation problem in repairable series–parallel systems by NSGA II
Bi-objective optimization of the availability allocation problem in a series–parallel system with repairable components is aimed in this paper. The two objectives of the problem are the availability of the system and the total cost of the system. Regarding the previous studies in series–parallel systems, the main contribution of this study is to expand the redundancy allocation problems to syst...

Introduction: The present study was conducted to identify the components of the participatory management model in the ninth-grade science classroom in a district of Karaj. Classroom participatory management is an important part of the education process and facilitates the teaching-learning system and facilitates the learning process. Studies in Iran show that classroom management has received l...
متن کاملDesigning and Authenticating a Problem Based Curriculum model in Elementary Mathematics
Abstract 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 ...
