هدفت هذه الدراسة إلى استقصاء تغير مستويات (فان هيلي) للتفكير الهندسي عند الطلبة معلمي الصف في (التعليم المفتوح) إثر دراستهم مقرر المفاهيم الهندسية و طرائق تدريسها، و علاقتها بتحصيلهم الدراسي فيه، في كلية التربية بجامعة دمشق. و قد تكونت عينة البحث من ( 101 ) طالب و طالبة من الطلبة المعلمين في السنة الرابعة (ذكوراً و إناثاً، سوريين و (أونروا) (UNRWA). و استخدم الباحث اختبار (فان هيلي) للتفكير الهندسي (بمعامل ثبات ألفا كرونباخ = 0.82 في البيئة السورية)، إلى جانب اختبار أعده الباحث لقياس التحصيل الدراسي في مقرر المفاهيم الهندسية و طرائق تدريسها (بمعامل ثبات ألفا كرونباخ = 0.89). أظهرت نتائج الدراسة أن مستويات (فان هيلي) للتفكير الهندسي عند طلبة معلمي الصف في (التعليم المفتوح) قد تغيرت إيجابياً بعد دراسة مقرر المفاهيم الهندسية و طرائق تدريسها، إِذ تقدم معظم الطلبة المعلمين نحو مستويات أعلى في التفكير الهندسي. كما أظهرت نتائج الدراسة وجود علاقة ارتباط إيجابية قوية ذات دلالة إحصائية عند مستوى الدلالة ( 0.01 ) بين درجات الطلبة المعلمين على اختبار فان هيلي للتفكير الهندسي و درجاتهم على اختبار التحصيل في الهندسة على مستوى ( المجموعة الكلية (0.555 )، مجموعة الذكور ( 0.542 )، مجموعة الإناث ( 0.583 )، مجموعة السوريين ( 0.544 )، مجموعة (الأونروا) ( 0.611 )). و هذه النتائج تتيح للمقياسين الاستخدام بشكل متبادل عند الضرورة. و قد قدم الباحث مجموعة من المقترحات و التوصيات في ضوء نتائج الدراسة.
This study aimed to investigate changes in Van Hiele levels of Geometrical thinking for open education student teachers upon taking the course on (Geometric Concepts and its Methods of Teaching) and their relationship to achievement, in the College of Education at Damascus University. A sample of (101) student teachers was chosen (males and females, Syrians and UNRWA) from the fourth – year open education student teachers. The researcher used the Van Hiele Geometrical Thought Test (with α = 0.82) in the Syrian environment, and an achievement test (with α =0.89). The results showed positive changes in Van Hiele levels of geometrical thought in open education student teachers, after taking the course of (Geometric Concepts and its Methods of Teaching), where most student teachers advanced to higher levels of Geometrical thinking. In addition, the results showed a strong significant positive correlation (at level of significance = 0.01) between student teachers' scores on the Van Hiele Geometrical thinking test and their scores on the achievement test at groups of (whole group= 0.555, males= 0.542, females= 0.583, Syrians= 0.544, UNRWA= 0.611). These results could help teachers to use the two tests mutually. The researcher presented several recommendations and suggestions, in light of the study findings.

This study aimed to extent of the distribution of the Van Hiele levels in geometrical reasoning in secondary school students (the second secondary grade), and its relationship with geometric- proof And logical-mathematical thinking, And a random samp
le of (200) two hundred students was chosen from both genders from the public schools in the Lattakia city, The research used the Van Hiele geometry test, and she used Achievement test for writing proofs in Geometry, And logical-mathematical thinking test. The results showed the Van Hiele levels of geometrical reasoning were present distributed at the first fourth levels with varying degrees in secondary school students (the second secondary grade), and There was a strong correlation between the two variables (Van Hiele / Geometric proof) for students, and There is a strong and positive relationship between the two variables(Logical-mathematical thinking / Geometry proof) for students, and There was a strong correlation between the two variables (Logical-mathematical thinking / Van Hiele) for students.
The present study aimed to find out the fourth grade
pupils trends of basic education towards the unit is designed in
accordance with the expansion Elaboration theory in Social
Studies and its relation to their academic achievement
, The research
er analyzes the content of the first three
units to book social studies for students in the fourth grade of
primary education, and re-organize content according to the
steps Elaboration theory expansion, and teacher preparation guide
on the basis of the proposed olive model in design education, and
testing of academic achievement and gauge students' attitudes
towards expansion theory, and after confirmation of the validity
and reliability of the tools, the researcher applied to a sample of
30 pupils, and the study results that pupils trends about
expansionist theory was positive and that there are no differences
in the students' attitudes towards unit designed according to
Elaboration theory expansion due to the variable Gender (Male,
Female) and that there is a statistically significant between pupils
trends link towards unit designed according to the expansionist
theory and academic achievement.
The research aims to identify the correlation between selfefficiency
and achievement motivation, And knowledge of the
differences between the mean scores of the respondentsto the
public self-efficiency scale and measure achievement motivation
according to the variables of sex and school year.
The current research aims to identify the nature of the
relationship between theCharisma to University Professor and its
relationship to effective teaching from the point of view a sampleof
open education students at the University of Damascus. According
variable specialization school (Kindergarten, accounting).
The research aimed to identify the degree of employing
constructivist teaching methods by classroom teachers in the first cycle
of basic education, and to know the differences among the research
sample individuals in the degree of employing these
methods
according to the variables of (educational qualification, and years of
experience). The sample of the research consisted of (288) teachers in
the first cycle of basic education in Damascus state schools. The
sample was selected using the simple random way, and the
questionnaire of employing constructivist teaching methods (prepared
by the researcher) was applied to them after it was verified for its
validity and reliability.
