The aim of the research is to identify the effect of using the (K U D) strategy in solving
mathematical problems among primary school students, and in order to achieve the goal
of the research, the following null hypothesis was developed:
There is no statistically significant difference at the significance level (0.05) between
the mean scores of the experimental group students who will study mathematics
according to the (KUD) strategy and the scores of the control group students who will
study the same subject according to the usual method in the test of solving mathematical
The research sample consisted of (67) female students of the fifth grade of primary
school in (Sheikh Maarouf Elementary School) for the academic year (2020-2021),
distributed into two groups, one of them experimental and studied according to the
(KUD) strategy, with (34) female students and the other control, which were studied
according to the usual method by (33) students.
The two groups were rewarded in the variables (chronological age calculated in months,
intelligence, academic achievement of the parents, previous knowledge in mathematics,
and previous achievement in mathematics), as the research tool represented by (the test
of solving mathematical problems) was built.
The test of solving mathematical problems consisted of (16) objective items, and the
validity of the test was verified, and the reliability coefficient was acceptable, as the
KewderRichasson _20 equation was used to find it (0.85).
After the end of the experiment, the test of solving mathematical problems was applied
to each of the two groups (experimental and control), and using the appropriate
statistical means, the results showed a statistically significant difference between the
experimental and control groups in the test of solving mathematical problems in favor
of the experimental group.
In light of the research results, the researcher presented some recommendations and
suggestions for the purpose of conducting subsequent research and studies.
