The effectiveness of a program based on the lesson study strategy in developing the reflective teaching skills of pre-service science teachers

Based on self observation & previous studies' results, it appeared that there is a shortage in reflective teaching skills for pre-service science teachers, so this study tried to recognize the effectiveness of lesson study strategy based program in developing reflective teaching skills for pre-service science teachers, to achieve such aim; quasi-experimental approach (one group design with pre-post measuring), committed throgh next procedures: preparing a list of reflective teaching skills for pre-service science teachers- preparing a measure & an observation rating scale for measuring the extent to which pre-service science teachers have reflective teaching skills, Preparing the trainee's and trainer's guide for a lesson study strategy based program to develop reflective teaching skills for pre-service science teachers, choose the study group randomly among the 4^th year science specialties from Qena faculty of education, & apply the experiment of the study on them, results of the study indicate the effectiveness of lesson study strategy based program in developing reflective teaching skills for pre-service science teachers; the differences between pre- post performance of the study group at both the measure & observation rating scale for the extent to which pre-service science teachers have reflective teaching skills, were statistically significant at the level of 0.01 with high size effect.
