فاعلية استراتيجية شكل البيت الدائري في تنمية مهارات ما وراء المعرفة والاستقصاء الرياضي لدى تلاميذ المرحلة الإعدادية

الملخص EN

The research aimed at identifying the effectiveness of using round house diagram strategy in developing metacognitive and mathematical investigation skills among preparatory stage students.

the research adopted the quasi experimental design of experimental and control groups with pre / posttests, where the pre-tests aimed at ensuring that the students of the two groups were equal before the administration, while the identifying the effectiveness of using the independent variable (round house diagram strategy) on developing the two dependent variables (metacognitive and mathematical investigation skills) of preparatory stage pupils.

some results were revealed as follows: • there is a statistically significant difference at the level of (0,05) between the mean scores of the experimental and control groups in the overall meta cognitive skills scale and its sub-components (planning, control and observation, evaluation) in favor of the experimental group.

• there is a statistically significant difference at the level (0.05) between the mean scores of the students of the experimental and control groups in the test of mathematical investigation skills as a whole and its sub-components (observation-inference–measurement–interpretation) separately, in favor of the experimental group.

• there is correlation and statistical function at the level (0.05) between mathematical inquiry skills and metacognitive skills.

in the light of these results, some recommendations and suggestions were made, including: providing training programs for mathematics teachers in the preparatory stage on how to use round house diagram strategy in teaching to develop metacognitive and mathematical investigation skills for among preparatory stage students, study the effectiveness of using a proposed teaching problem solving input in the development of metacognitive and mathematical investigation skills for among preparatory stage students.
