الملخص EN

The aim of the research is to know the effect of the use of logical line up strategies (L.

L.

U) and activation of previous knowledge (KW.

L) in the achievement of mathematics for primary fifth female pupils).

To verify the research aim, the following hypothesis was formulated: There is no statistically significant difference at the level at (0.05) between the mean scores of the first experimental group (who were studying using the logical lineup strategy) and the second experimental group (taught using the previous knowledge activation strategy) in the mathematics achievement test.

The study sample consisted of (70) female pupils of the primary fifth class, divided into two groups (35) female pupils in the first experimental group and 35 female pupils in the second experimental group.

The two groups were equivalent in a number of variables, ages by Previous achievement of mathematics, intelligence test, and previous knowledge test in mathematics), The research tool was prepared as the " achievement test", which is the final form of (24) objective items of (multiple choice) of the four alternatives.

The face validity is got, also the coefficient of difficulty and the coefficient of discrimination and the effectiveness of alternatives to the objective items.

The reliability of the Test items is got by using the Keoder-Richardson-20 equation (0.83).

After applying the test to the research sample and analyzing the results statistically, the results revealed the superiority of the experimental group was which studied the logical line up strategy in the achievement test.
