الملخص EN

The present study aimed at identifying the effectiveness of using some habits of mind in teaching Geometry on the acquisition of the concepts and relations and in reducing geometrical apprehension of first year preparatory school students.

To achieve the objectives of the study the researcher developed the measurement instruments including a test to measure students' acquisition of geometrical concepts and relations in the lesson of 'Parallelism' taught according to Frayer's model and a geometrical apprehension scale which included the following domains (geometrical comprehension, geometrical achievement and having a test in geometry).

The instructional material included a teacher's guide and students' handouts.

The content validity of the instruments was established by a panel of jury members.

The reliability of the instruments was calculated by SPSS program using Alpha's Cranach's coefficient as it was (0.91) for the test and (0.84) for the geometrical apprehension scale.

Ninety two male and female students enrolled at the first year preparatory stage participated in the study.

They were divided into two intact groups (Treatment and non-treatment) forty six for each.

Results revealed the effectiveness of using habits of mind in teaching geometry in increasing students' acquisition of geometrical concepts and relations and in reducing geometrical apprehension of the treatment group compared with the treatment one in the post testing, students of the treatment group showed no difference in the pre-post administration of the apprehension scale unlike their counterparts of the non-treatment group who showed high level of apprehension in the post administration after studying the content of geometry using the regular method of instruction.

Discussion of the findings, recommendations and suggestions for further research were presented.
