The Effectiveness of the Visual Teaching strategy in chemistry achievement and developing the scientific thinking of the second – year male students

Abstract

This research aims at the impact of the visual teaching strategy on the achievement in chemistry and developing the scientific thinking of the second – year male students . year secondary male students through proving the following two hypotheses : 1-There is no difference in the statistical sign at the sign level (0.05) between the average of male students' achievement marks in the experimental group and the average of the male students' achievement marks in the control group .2-There is no difference in the statistical sign at the sign level (0.05) between the average of the pre-test . and post-test . of the scientific thinking of the male in the experimental group and average of the pre-test . and post-test . of the scientific thinking of the male students in the control group.Tala-Al-natheed secondary school in Baquba has been chosen intestinally as the experiment field. The research sample consist of (70) male students from the second – year secondary school who are divided in to two equal groups. Then the equivalence was found. The research requirements are prepared and experiment is applied from 8-10-2015 till 23-12-2015 The researcher has prepared two tests the first one is an achievement post-test which consist (40) items from the type of multiple – choice test , and the second is the scientific thinking test which consist (30) items distributed on 5 areas.After the statistical Analysis was found , the achievement test reliability has been found by using half – split method , and the scientific thinking reliability has been found by using Alfa chronbach , formula . The results have been analyzed which show the male students excellence in the experimental group more than the male students in the control group in each of achievement and scientific thinking. The researcher submitted a number of conclusions, recommendations and suggestions.
