The present study aims at knowing the effect of Woods' model in correcting the geographical missUnderstanding for first stage students. In order to realize the objective of this study, the researcher used an experimental design with partial adjustment which is experimental group with another control group. The research is confined to the first four chapters of the boon of the principles of geography to be studied for the first stage in the academic year (2010/2011) in Iraq. The researcher chooses purposely the chose a staple form the first stage in Hay Al-Jama'a School for boys, in order to apply the experiment. The total number of the sample was (60) students who were distributed randomly as (30)per group. The researcher matched two groups in terms of ( geography diagonal test, intelligence level, Age, parent education). Then, the researcher tried to adjust a series of variables that might affect the variable. The researcher conducted the research on two stages; diagonal stage: in which he tried to analyze the book matter under the experiment and the subjects of geography which were taught to the groups of students in previous years (fifth and sixth primary stages). The repeated concepts were derived in the first stage and the previous stages. They were (20) concepts on the basis of which a diagonal test was adopted the type of multiple choice to measure the level of understanding in the cognitive field of Bloom's classification. The number of items attained (20) items each item one. On that basis the test of the items of wrong understanding. If the error rate exceeded (%34) above for the sample. The validity and constancy was verified and he discriminatory power of the items and the difficulty coefficient. It turned out after analysis that there are (16)concepts of wrong understanding for the second stage, correction. The procedures of this was applied on a diagonal sample which had been already subdivided into two groups; the experimental group which is taught according to Wood's method and the control group which is taught according to traditional methods. After ending the study of the four chapters of the Geography book, and analyzing the data statistically by using Chi square, it was found that the excel of the experimental group which is taught according to Wood's model over the control group which is taught according to traditional methods. In the light of which the following was found: 1. The effectiveness of Wood's model in correcting the wrong concepts more than the traditional ones. 2. The conventional methods have helped only in a limited way to correct some of the wrong concepts for the first stage students. The researcher has come up with the following recommendations: 1. To use Woods' model in teaching the general principles of geography for its effectiveness in correcting the wrong concepts. 2. The necessity that teachers of geography to have knowledge in the teaching models like Woods' Model. 3. Familiarize geography teachers with the methods of diagnosing the wrong conception for students to correct them In the light of the results, the researcher comes up with suggestions like conducting studies in the effect of: 1. Woods' Model on other stages and materials. 2. Woods' Model in variables affiliated to like innovative thinking, motivation and acquisition of the scientific skills. 3. A comparison study between Woods' model and other models not depending on the constructive philosophy.

Characterization of Delamination Effect on Free Vibration of Composite Laminates Plate Using High Order Shear Deformation Theory
...Show More Authors

 A dynamic analysis method has been developed to investigate and characterize embedded delamination on the dynamic response of composite laminated structures. A nonlinear finite element model for geometrically large amplitude free vibration intact plate and delamination plate analysis is presented using higher order shear deformation theory where the nonlinearity was introduced  in the Green-Lagrange sense. The governing equation of the vibrated plate were derived using the Variational approach. The effect of different orthotropicity ratio, boundary condition and delamination size on the non-dimenational fundamental frequency and frequency ratios of plate for different stacking sequences are studied. Finally th

Study of Mechanical Characteristics for Polymer Composite Reinforced by Particles of (Al2O3) or (Al)
...Show More Authors

A particulate polymer composite material was prepared by reinforcing with the Aluminum Oxide (Al2O3) or Aluminum (Al) metallic particles with a particle size of (30) µm to an unsaturated Polyester Resin with a weight fraction of (5%, 10%, 15%, 20%).

Tensile test results showed the maximum value of elastic modulus reached (2400MPa.)  in the case of reinforcing with (Al) particles with weight fraction (20%) and (1500 MPa.)  in the case of reinforcing with (Al2O3) particles of the same weight fraction.

  When the impact and the flexural strength tests were done, the results showed that flexural strength (F.S), maximum shear stress (τmax), impact strength

One of the difficulties that the kindergarten institution face is the lack of specialized teachers to work with the children at the kindergarten age for the majority  of this stage teachers were prepared to teaech in the elementary stage while the kindergarten child needs ateacher who is aware of the characteristics  and the demands of his growth and his behavioral emotional and social problems.

Therefore the best teacher must be chosen for the kindergarten and qualifying  her educationally in all that this qualifying  includes of  knowledge's.

This paper aims to find new analytical closed-forms to the  solutions of the nonhomogeneous functional differential equations of the nth order with finite and constants delays and various initial delay conditions in terms of elementary functions using Laplace transform method. As well as, the definition of dynamical systems for ordinary differential equations is used to introduce the definition of dynamical systems for delay differential equations which contain multiple delays with a discussion of their dynamical properties: The exponential stability and strong stability

The Relationship between Fiscal Policy and Human Development Analytical Studay Of Iraq Using The (ARDL)Model
...Show More Authors

Fiscal policy is one of the important economic tools that affect economic development in general and human development in particular through its tools (public revenues, public expenditures, and the general budget).

It was hoped that the effects of fiscal policy during the study period (2004-2007) will positively reflect on human development indicators (health, education, income) by raising these indicators on the ground. After 2003, public revenues in Iraq increased due to increased revenues. However, despite this increase in public budgets, the actual impact on human development and its indicators was not equivalent to this increase in financial revenues. QR The value of the general budget allocations ha

The Idea of our tagged research (The Impact of Dystopia In the
Formation of Narrative Time) Is summed up by monitoring the theme
of dystopia and Its impact on shaping the techniques of narrative time,
and In order to prove the Idea of our research, our choice focused on
the fictional production of a group of Iraqi women novelists that was
published In the time period (2003 AD-2020 AD) Through this theme,
we monitored how the temporal paradoxes operate from anticipation
and retrieval In the fragmentation of the narrative time, whichh in turn
presented a picture of the Iraqi reality In which the human Image
crumbled and its values were shattered and fragmented.

The bank risks has greaten and changed in its nature under the developments of financial liberalization, banking innovation and increasing use for new financial instruments which created by the huge technological advancement happened in the banking  industry. So that, banks in large choose to base the profitability measures adjusted for risks; that is we introduced this research. The most important reason led us to do this is the restriction to use the modern statistical methods by trade bank in Arab countries equally with world banks which were the antecedent to base those models. Therefore, the research problem is embedded in the banks need to use measures that link between profitability and risks and this is what achieved by RARC
