Abstract

Aim of Study: To identify the effectiveness of using (K.W.L) strategy on developing certain skills related to generating and evaluating information in science among intermediate student's school. Study procedures: Researcher in this study focused on two research approaches, a theoretical aspect derived from existing related studies and a field aspect which follows the experimental method with a quasiexperimental design known as pre and post test for the two study groups (the experimental and the control). Materials and methods of the Study were designed and collected in one unit which reformulated according to the (K.W.L) strategy. In addition, tools such as teacher’s guide, student’s handbook and tests for generating and evaluating information were also prepared. After examining the reliability and validity of these tools, the Study has been conducted on total (63) students, (31) of them were in the experimental group using the (K.W.L) strategy and (32) students in the control group researching with the traditional method. Lastly, date collected from the study has been processed by using MANCOVA, MANOVA tests and ω square. Results: results of the study showed there were statistical differences in the post-test for the experimental group in skills of generating information. In addition, statistical differences showed in the post-test to skills of evaluating information for the experimental group as well. The effectiveness of the strategy on some skills of generating and evaluatinginformation test ranges between medium and large. Finally, based on the current study and its results several recommendations and proposed studies have been suggested.
