The Effect of Teaching on the Skills of Logical Thinking in the Achievement of Student's Achievement in Biology

The aim of the research was to identify the effect of logical thinking skills on the achievement of the fifth grade biology students. To achieve the goal, the researchers put the zero hypothesis which states: There is no statistically significant difference at the level of (0.05) between the averages scores of the female students of the experimental group will be guided by the logical thinking skills. The average number of female students of the control group will study according to the usual method in the biology test. In order for the researchers to apply, the experiment was applied in the second half of the academic year (2018–2019). If the sample consisted of (82) fifth grade female students of Al-Baqir High School for Girls. And random image were divided into two groups of 36 students per group. The two groups were equivalent in the following variables: age, decision scale, testing the previous information of the new material, and in light of the behavioral objectives and the relative importance of the content, (40) paragraph of multiple choice, and the researcher has achieved the specifications of the cykometric test, the experiment continued to apply for (8) weeks.
