The effectiveness of using a constructive learning strategy at the level of learning Handball defence skills

In accordance with the nature of the research and to achieve its goal and test for the validity of hypotheses, the researcher used the experimental approach in the design of measurement (pre- post) of two groups, one experimental and the other a control and suitability to the nature of research.
Research community:
