أثر توظيف كل من استراتيجيتي (العصف الذهني و التعام البنائي)‎ في التفكير الاستدلالي و الدافع المعرفي لطلاب الصف الثاني المتوسط

الملخص EN

The research aims to identify the impact of the use of each of the constructivist learning strategy and brainstorming in the teaching of mathematics in the development of deductive thinking and motivation cognitive development among third-graders average.

Find community consists of all second grade average students for the academic year (2013 - 2014) of medium-Nasser Boys / Karkh third totaling 188 students.

Distributors and random manner (five people), he chose them randomly Hall (c) to represent the first experimental group, which is considering using (constructivist learning strategy) and Hall (b) The second experimental group taught using (brainstorming strategy).

The sample of the study amounted to 76 students divided into two divisions, the number of the first experimental group students (38) and experimental group II (38) students.

Although the researcher following the random selection method in the two sets of search was careful before you start applying his experience on a parity between them in some of the variables that are believed it may affect the results of the experiment: the chronological age in months.

The degree of intelligence.

Former achievement in mathematics.

Inferential thinking scale.

Previous test information.

Motivation cognitive scale.

The two groups are equivalent in all the variables.

The search tools has the researcher built inferential thinking in mathematics scale, commensurate with the content of mathematics for Grade Average semester, the measure of the number of arbitrators with expertise and specialization to express their views on the validity of paragraphs where identified and covered what was prepared for him and the safety of building paragraphs and determine the level determined by the paragraph.

Promised paragraph honest if I got the approval of 80% or more of the views of the arbitrators, and therefore the number of paragraphs of the scale (36) paragraph.

Total reliability coefficient (0.78) is a good reliability coefficient for the tests is inhalers and at the expense of the difficulty coefficient for each paragraph of the test was found to range between (0.27 - 0.87) and that any clause in the distribution coefficien
