الملخص EN

The problem of the research: The problem with the research in the following two questions: 1) How effective is the use of graphic organizer strategy in teaching biology in the development of some scientific concepts at the first year of secondary students? 2) How effective is the use of graphic organizer strategy in teaching biology in the development of some systemic thinking skills at the first-grade secondary students? Research Objectives: 1) Measure the effectiveness of using graphic organizer strategy in the teaching of biological sciences in the development of some of the scientific concepts of the first year of secondary students.

2) Measure the effectiveness of using graphic organizer strategy in the teaching of biological sciences in the development of some of the systemic thinking skills at the first-grade secondary students.

Research Results: 1) There is a statistically significant difference between the averages of the group of the experimental and control group in the achievement test of scientific concepts for the experimental group.

2) There is a statistically significant difference between the mean scores of the experimental group in the two applications for pre and post test the collection of scientific concepts in favor of the post test.

3) There is a statistically significant difference between the averages of the group of the experimental and control group in Systems Thinking scale for the experimental group.

4) There is a statistically significant difference between the mean scores of the experimental group in the two applications for pre and post measure of systemic thinking in favor of the post test.
