الصعوبات التي تواجه طلبة معلم الصف في اكتساب مفاهيم و مهارات الهندسة المستوي و أسبابها

Abstract EN

This research aimed to investigate extent of difficulties of learning concepts and skills of plane geometry from students' views of "class teacher" specialization, through answering these two questions : 1.

At what degree students face difficulties in learning concepts and skills of plane geometry from students' views of "class teacher" specialization ? 2.

Is there any significant statistical difference of what students face in learning concepts and skills of plane geometry, from students' views of "class teacher" specialization due to sex, specialization in secondary education, and student cumulative average in the University ? To answer these two questions, a questionnaire of (72) items was built and classified to five domains: geometry concepts, characteristics of geometric figures, mathematical proof, geometric measurements, and geometric constructions.

Main results were : -Students face difficulties in mathematical proofs.

-Students face difficulties in building learning Facts of triangles congruencies, and its use in proving geometric theorems and solving their problems.

-Students face difficulties in learning facts of metric units of length and area, and their relations and applications.

-No significant statistical differences in degree of difficulties students face in learning concepts and skills of plane geometry due to sex.

-Existence of significant statistical differences in degree of difficulties students face in learning : geometric concepts, geomtric measurements, and geometric constructions due to specialization in secondary education, in favor of art branch.

-Existence of significant statistical differences in degree of difficulties students face in learning geometric concepts and skills due to student in the University, in favor of "pass" Level.
