Abstract EN

The purpose of das study was to investigate Effectiveness Using of Mkhty Hand Strategy to Teaching of Hydraulic Course m Developing of Hydraulic Concepts and Practical Thinking for Third- Year Secondary Industrial School Students.

The research' samples consisted of 64 students specialized m architecture distributed mto two groups (experimental and control), with 32 students m each m Mechanical Industrial Secondary Assiut School at Assut Govemorate.

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 teachirc unit of ‘Static Properties of Liquids”,(4) Home worksheets and an Hydraulic concepts test in die unit of "Static Properties of Liquids", and practical thinking test.

The content of die unit ‘Static Properties of Liquids’ m die teaching planning and Hydraulic course was analyzed for third-year secondary industrial school students, sanitary work and water network specialization to determine die 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 ii die unit ‘Static Properties of Liquids’.

Hie tools of the study were administered using a pre-post deskn on die study groups, and the experimental groip was taught by using Mighty Hand Strategy in and us mg die Traditional method with die control groip.

The took of the study were post-administered and die 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.

Hie results of die stud)- indicated that Using of Might}' Hand Strategy to Teaching of Hydraulic Course was effective in developing concepts and Practical Thinking of die experimental group as compared to die control.
