Levels of Geometrical Thinking of College of Education Ibn AI Haithem Students

The  present    research  is  aimed  to  know  the  levels  of  geometrical thinking of college of education " Ibn Al Haitham students I second class" . The sample of the research consists of ( 50 ) male & female students , that were chosen randomly during  the academic year 2002-2003 .

To verify the aim of the study , the researcher reviewed the previous cognitive literature , and limited his study to the ( comprehending  analytic , ordinal , and inferential ) levels of geometrical thinking .

He  constructed  a  test  that  was  consisted  of  ( 25  )  items  .  The  test  was

presented to a committee of experts in mathematics and methods of teaching math . to assure its validity . The committee agreed on all test items .

A pilot sample consisting of (20) male & female students was chosen from  the  research  population  to confmn  the   reliability  of  the test  . The researcher  used anumber  of statistical  means to analyze data, one of them was building .

The results of the research showed a· clear weakness in the levels of

geometrical  thinking among the research sample and according to this result, there  is  a  need  for  further  research  and  concern  on  quality  of  teaching geometries . This subject develops all levels of geometrical thinking . These results  determine  that  students  were  not  mastering  the  basic  geometrical concepts , although most of those concepts are considered a basic request for the  academic  level  that  was  chosen  for  this  study  .The  researcher  stated many recommendations  one of them was  to improve the quality of teaching geometries  with construction  on its different features that develop levels of different geometrical thinking .The researcher suggested more researches  in this field to be conducted and using samples from different level samples of students.

The study of comparing the cognitive teaching method effect ( total and analytic ) in teaching the counter- attack of Epee

The research's aim is to place two teaching methods ( total and analytical method) and to know which one of them is better than the other in teaching the counter-attack with Epee. The researchers have used the experimental method for being considered suitable to solve the problem of the research. The sample of the research includes third –stage female students of college of physical education and sport sciences / Baghdad University in the subject of fencing, their number amounted 60 female students. It has been used SPSS for processing the results. They have concluded that the two groups of the research and the two methods (( total and analytical) have learnt the counter- attack of the two over mentioned groups. they have recommended to c

Effect of training on anaerobic endurance according to the average efficiency in the development of physical players Wrestling Judo

Wrestling Judo, one of the sports that have seen greatdevelopment in recent years in the world, requiring preparationphysically special, which is to be determined physical aptitude of thebad functional efficiency of the heart and lungs, Efficient physicalclosely linked to the ability of the player performance, as the physicalaptitude to play an important role the possibility of control over theaspects and physical skills during training and competition.The study aims to determine the effect of training on anaerobicendurance according to the average (30-60 sec) in the development ofphysical aptitude for judo players. Used a much more extremeexperimental method on a sample was Blaabat national teamwrestling judo and numbers of 16 for the play

Minimizing the Principle Stresses of Powerhoused Rock-Fill Dams Using Control Turbine Running Units: Application of Finite Element Method

This study focuses on improving the safety of embankment dams by considering the effects of vibration due to powerhouse operation on the dam body. The study contains two main parts. In the first part, ANSYS-CFX is used to create the three-dimensional (3D) Finite Volume (FV) model of one vertical Francis turbine unit. The 3D model is run by considering various reservoir conditions and the dimensions of units. The Re-Normalization Group (RNG) k-ε turbulence model is employed, and the physical properties of water and the flow characteristics are defined in the turbine model. In the second phases, a 3D finite element (FE) numerical model for a rock-fill dam is created by using ANSYS®, considering the dam connection with its powerhouse

Influence of concentration on the structural, optical and electrical properties of TiO 2 : CuO thin film Fabricate by PLD

In this work, Titanium oxide thin films doped with different concentration of CuO (0,5,10, 15,20) %wt were prepared by pulse laser deposition(PLD) technique on glass substrates at room temperature with constant deposition parameter such as : pulse (Nd:YAG), laser with λ=1064 nm, constant energy 800 mJ , repetition rate 6 Hz and No. of pulse (500). The structure , optical and electrical properties were studied . The results of X-ray diffraction( XRD) confirmed that the film grown by this technique have good crystalline tetragonal mixed anatase and rutile phase structure, The preferred orientation was along (110) direction for Rutile phase. The optical properties of the films were studied by UV-VIS spectrum in the range of (360-1100)
