فاعلية استراتيجية مقترحة وفق التفكير البصري في تحصيل مادة الفيزياء و الحدة الذهنية لدى طلاب الصف الخامس الإحيائي

الملخص EN

The aim of the current research is to identify the effectiveness of a proposed strategy according to visual thinking in the achievement of physics and mental sharpness among fifth-grade biology student, by verifying the following null hypothesis : there is no difference or statistical significance at the level (0.05) average scores of the experimental group students which was studied according suggested strategy and the average scores of the students of the control group who studied in the usual way at the level of achievement in physics and mental sharpness .

The research limited for fifth grade biology students in the middle and high schools of the day affiliated to the directorate of education al-Diwaniyah center for the academic year (2020-2021), the research chose Al-Zaytoun high school intentionally, then two division were chosen out of four divisions for the fifth grade biology were randomly selected, the sample number was (71) students, and by (35) students for the control group, which studied in the usual way and (36) students for the experimental group, which studied according to the proposed strategy, the pilot and officer groups have been equal in a number of variables are the time-old in the months of the semi-year test degree with physics and previous information, for the purpose of achieving my research goals, researchers adopted a threat to a multi-choice (35) paragraph, the test was verified and its stability was also verified as the discriminatory force was calculated for its paragraphs, the mental acuity test was also built, which consisted of (45) items distributed over 3 sub-dimensions, the validity and reliability of the test were verified , and the discriminatory power of the items was calculated, the results showed the superiority of the students of the experimental group that studied according to the proposed strategy over the students of the control group that studied in the usual away in achievement in physics and mental acuity for the fifth grade biology students, thus, the null hypothesis was rejected accordingly, the researchers recommended using the proposed strategy in teaching physics and suggested conducting other studies for other stages of study and different study subjects to know the effectiveness of the proposed .
