إستخدام استراتيجية اليد المفكرة في تدريس مقرر الهيدروليكا لتنمية المفاهيم الهيدروليكية والتفكير العملي لدي طلاب الصف الثالث الثانوي الصناعي



The purpose of this study was to investigate effectiveness using of mighty hand strategy to teaching of hydraulic course in developing of hydraulic concepts and practical thinking for third-year secondary industrial school students. The research' samples consisted of 64 students specialized in architecture distributed into two groups (experimental and control), with 32 students in each in mechanical industrial secondary Assiut school at Assiut governorate. Research tools included: 1) teaching unit of ‘static properties of liquids’, planned according to mighty hand strategy. 2) A student activity worksheets in teaching unit of “static properties of liquids”. 3) A teacher’s guide of teaching unit of “static properties of liquids”. 4) Home worksheets and a hydraulic concepts test in the unit of “static properties of liquids”, and practical thinking test. The content of the unit “static properties of liquids” in the teaching planning and hydraulic course was analyzed for third-year secondary industrial school students, sanitary work and water network specialization, to determine the weights of the concepts included in the unit to build the hydraulic concepts test and the preparation of teacher’s guide and student’s activity worksheets and home worksheets in the unit ‘static properties of liquids’. The tools of the study were administered using a pre-post design on the study groups, and the experimental group was taught by using mighty hand strategy in and using the traditional method with the control group. The tools of the study were post-administered and the appropriate statistical procedures were used so as to calculate the differences in the means of scores for both the experimental group and the control one. The results of the study indicated that using of mighty hand strategy to teaching of hydraulic course was effective in developing concepts and practical thinking of the experimental group as compared to the control.
