فاعلية وحدة مطورة في مادة الأحياء وفقا للإتجاهات الحديثة في تنمية التحصيل و مهارات التفكير العلمي لدى طلبة الصف الثاني الثانوي باليمن

Abstract EN

The study aimed to measure the effectiveness of a developed study unit in biology at the secondary stage in Yemen in the light of recent trends in scientific education in developing achievement and scientific thinking skills.

to achieve this, the researcher used the descriptive approach and the quasi-experimental approach, by building and developing a study unit and measuring its effectiveness in developing achievement and developing scientific thinking skills, using an interview form to identify the most important modern trends and projects, an achievement test and a scale for scientific thinking skills to measure the effectiveness of the study unit.

the study sample consisted of (60) students; out of which (30) students are an experimental group and (30) students are a control group, and modern trends of scientific education and the development of the study unit (the immune unit) have been identified in their light.

the study concluded that there are statistically significant differences between the average achievement of the experimental group.

the experimental group obtained a total average (18.47 out of 20) and a percentage (91.67%) in contrast to the control group getting a total average of (15.06 out of 20).

And a percentage of (74.83%) in the achievement test, and the Eta coefficient of influence was (0.96), which indicates that there is a significant effect of the proposed unit and in the scientific thinking skills scale, the experimental got a total average (19.93 out of 25) and a percentage of (79.73%) ; In contrast, the control group got a total average of (17.43 out of 25) (69.73%), and the difference in the two scales is statistically significant, at the level (α ≥ 0.05) in favor of the experimental group, which confirms the effectiveness of the unit.

In light of the results, the researcher recommended making use of the developed unit as a model in developing the biology curriculum for the secondary stage in Yemen.

he also suggested conducting studies on teaching methods in accordance with modern trends in scientific education.
