The research aims to determine the effect of the video screen synthetic type in Sharable video lectures (chroma Key / Picture in picture) in developing the visual thinking skills of high school students in the science course and their attitude towards learning through participatory sites. The research sample consisted of 60 students in the first grade Secondary education Were randomly divided into two equal groups according to the experimental design of each group of 30 students, a test to measure the skills of visual thinking (visual differentiation - analysis of visual stimuli - perception of relations in visual form - the skill of conclusion of the subject), were used And a measure of the attitude towards learning from sharable video web sites. Two Experimental Processing were designed according to the screen synthetic type in Sharable video lectures, one using a chroma Key and the other using a picture-in-picture type. The results showed a statistically significant difference (0.005) between the average scores of the experimental groups in thinking skills between the average scores of the two experimental groups in visual thinking skills for the experimental chroma-based video lectures. The results also indicated that there was no statistically significant difference between the mean scores of the two experimental groups in the Attitude toward learning from Sharable web sites due to the fundamental effect of the screen synthetic type in sharable video lectures. And there is a statistically significant difference between the average scores of the research sample members in the pre and post applications of the measure of the attitude towards learning through sharable web sites for the benefit of the post application. The study concluded that sharable video lectures promote the positive attitude of students towards learning from sharable web sites, Chroma-style video has greatly contributed to the development of visual thinking skills.
