أثر التدريس باستراتيجية الأمواج المتداخلة في التحصيل و التفكير الناقد عند طلاب الصف الرابع العلمي في مادة علم الأحياء

الملخص EN

This research aims to: identify the impact of the overlapping wave's strategy Overlapping Waves Strategy in the collection of material biology for students of the four grade average and Critical Thinking.

To investigate the aim of the research hypotheses formulated zero following: 1.

There is no difference statistically significant at the (0.05 level) between the average scores of students who are studying the collection in accordance with the strategy of overlapping waves Overlapping Waves Strategy and average students who are studying in the manner normal temperatures.2.

There is no difference statistically significant at the( 0.05 level) between the average scores of Critical Thinking for students who are studying on the strategy according to the waves overlapping Overlapping Waves Strategy and average students who are studying according to ordinary method and for the verification of these hypotheses degrees The search students average four in the secondary and high school in the morning community education Baghdad / Rusafa three was the four choice of secondary Al- Warethen Boys, indiscriminate appointment of the number of students (161) students divided between four people study.

It was chosen divisions (a, b) appointment random to represent a sample of the research was the randomly assigned to a group (a) to be the experimental group of (37) students studying physics according overlapping waves strategy, the group (b) that the group represents the control of (38), it taught the same material according to ordinary method, after repeaters students excluded statistically, and were and awarded the two sets of Search variables (chronological age, intelligence, achievement earlier in the sciences, Critical thinking, and previous information).

Researcher prepared research requirements actress select scientific material of physics first grade average for the academic year (2018 - 2017) also identified their one behavioral purposes and preparing lesson plans for the three experimental and control and have been prepared in achievement test consisting of (50) objective paragraph to multiple choice and adopted a researcher testing scientific thinking, was to make sure to psychology characteristics.

after the completion of the teaching of scientific material for the two dish tests (collection, and Critical Thinking), Started the application experience from 2018 – 4 -26 until 2017 – 10- 23 by two portions per week for each group.

And the researcher taught the two sets of search himself, and.

And has the data processing statistically the adoption of statistical bag for Social Sciences (SPSS), was reached following results: Outweigh the experimental group to the control group in the collection, and Critical Thinking statistically significant difference, and in the light of the results of the study the researcher presented a number of recommendations and proposals.
