The aim of the research was to prepare educational units using the meta-cognitive strategy in positive thinking and cognitive achievement and developing some complex skills in football for students, prepare two scales of positive thinking in football for students, identify the effectiveness of educational units using positive thinking and developing some complex skills in football for students, the researchers used the experimental method by designing the experimental and control groups to suit the nature of the problem. The community of students of the Secondary School for Sports Sciences affiliated to the General Directorate of Education in Rusafa II was identified, numbering (90) students, and the sample members were selected with a number of (90) students, i.e. (72.222%) of the research community, and the research sample was divided into a sample to prepare the scale under study, numbering (35) students, and the main experiment sample, numbering (20) students with a single experimental group system, and the number of the control group was also (20) students, and the number of the exploratory experiment group was (5) students, and (5) students were excluded for not committing. The researchers adopted the (Mahmoud, 2015) scale for positive thinking (appendix), as the scale consists of (23) statements, and the scale was corrected according to two answer alternatives, (A, B). After that, the exploratory experiment was used, which is considered "practical training for the researcher to identify the difficulties he encounters during the test to avoid them in the future" (Al-Shawk and Al-Kubaisi, 2004, p. 91). Therefore, the researcher conducted an exploratory experiment on (10/1/2025) on the exploratory experiment sample of (5) students. After that, the researchers conducted the pre-tests for the research sample, and then the main experiment was applied, followed by the post-tests. After that, the data for the pre- and post-tests for the experimental group were transcribed by the researchers, and statistically processed, and the results were obtained
