The research aims to investigate the effectiveness of (thinking diagrams)in: 1) Achievement of second Intermediate school students in chemistry. 2) Visual thinking skills of second intermediate school students in chemistry. To achieve the aim of the study, the following null-hypotheses have been formulated: 1) There is no statistically significant difference at the level (0,05) between the students' mean scores of performance of the experimental group which is taught chemistry by means of (thinking diagrams) and the mean scores of performance of control group which is taught chemistry according to traditional method of teaching during the test of chemistry for second intermediate school students. 2) There is no statistically significant difference at the level (0,05) between the students' mean scores of performance of the experimental group which is taught chemistry by means of (thinking diagrams) and the mean scores of performance of control group which is taught chemistry according to traditional method of teaching during the test of visual thinking skills for second intermediate school students. For the sake of investigation of the two hypotheses, the researcher conducted an experiment which took one complete course. It started on Wednesday (1/3/2017) and ended on Wednesday (26/4/2017). The researcher selected two groups experimental and control) randomly. (Published Abstract)
