The effect of using active learning model in the achievement of fourth -grade material in the de partment of physics teaching aids students and the development then critical thinking
...Show More Authors

Goal  of  research  is  to  investigate  the  impact  of the  use  of  effective  learning  model in the  collection  of  the  fourth  grade  students/Department of  physics in the material  educational methods  and the  development  of  critical thinking  .to teach  this goal  has  been  formulated  hypothesis cefereeten zero  subsidiary  of the second hypothesis  .To  investigate  the  research  hypothesis  were  selected  sample  of  fourth-grade  students of the  department  of physics at the university for the academic year (2015-2016) the sum of its members reached (71) students .and distributed this sample in to two divisions.one representing the exberimental groub and the other group represents the control and by (35-36)students respectively.i was conducted parity processon the two sets of search variables(intelligence.the collection of physics for previous year .chronological age.critical thinking). It has been teaching the experimental groub .according to the model of effective learnin g and the control  group according to the usual way. The researcher creating the necessary supplies for research and of identifying scientific material and formulation of behavioral purposes of article specific and preparing  lesson plans teach the experimental and control groups.according to the model of effective learning and the way ordinary.as well as carrying out the provision of teaching aids and tools laboratory of application experience.and requests the search and there are two tools.The first achievement test in the supject of the teaching aids where the researcher prepared and be in its final form(45) paragraph checksums objective of pairing tybe (conforming) and multiple choice surgeon (fill in the blanks) has been marked by total test honesty and consistency have been extracted difficulty discriminatory and strength to the level of paragraphs and all werew ithin the acceptable rang the difficulty and discrimination as well as the effectiveness of alternatives to the wrong vertebrae multiple choice.the second tool they test critical thinking prepared by (al-alwani.1999)and be its final form of the (75)paragraph checksums distributed(5)areas to measure the mental capacity critic representative skills (finding.evaluating arguments knowledge of assumptions.deducation.interpretation)has only researcher extracted sincerity and persistence. Abblied exberience .starting from the first semester of the academic year (2015-2016) as has beenthe bar-test procedure for critical thinking of students on the research sample (18/10/2015)and began to exberiment on (19/10/2015)and lasted on antire semester by three hours aweek to be Total college classes(27hours) for each groub.the experiment was completed after the application tools(achievement test and test critical thinking posttest)date(24/12/2015).After date collection and statistical analysis using altaia test for two independent samples:showed results as follows

1-There is astatistically significant difference between the average achivevment of the two sets of research in educational material means and in the experimental group

2-There is a statistically significant difference between the average skill development (conclusion.deduction.interpretation .and critical thinking as awhole)to the tow sets of search and infavor of the experimental group.in light of the search results researcher came out with a number 0f conclusions including the effectiveness of the model of effective learning(activelearning)in the collection of the fourth grade students of the physics department at the material educational methods and the development ofcritical thinking compared to the usual way.the researcher recommended a number of recommendations.including the establishment of training courses for teachers of physics on the use of model and new strategies in teaching including a model of effective learning(active learning) as well as attention to jean-authored book include book physics intellectual and skill activities including stimulates the energies of students and enhances their thinking in general skills and critical thinking in particular.complementing the current research .scholar proposals for future research mode

Investigation of the Natural Occurring Radioactive Material (NORM) in the cyprinus carpio fishes breeding in artificial lakes of Baghdad governorate
...Show More Authors

The steady consumption of fish led many researchers to study it preferences over other foods, especially for radioactivity content. The specific activity concentration (S.A) of natural occurring radioactive materials (NORM) have been measured for Cyprinus carpio fishes collected from several industrial fishes' lakes located in Baghdad governorate using gamma spectroscopy doped with high purity germanium coaxial detector (HPGe). Thirteen fishes' samples were collected from industrial lakes, three samples were collected from cages, and two samples were collected from Trigger River. The last two types of samples were collected in order to compare the results with it. The measured overall averages of S.A for Ra-226, Th-232, and K-40 were 58.

The Effect of Silver-Zinc Zeolite Incorporation on Some Properties of Condensation Silicone Impression Material
...Show More Authors

Background: elastomeric impression materials are indicated when a high degree of accuracy is required, due to their excellent properties like details reproduction, dimensional stability and tear strength but with main two disadvantages those are their hydrophilicity as well as the absence of antibacterial activity. This study aimed to evaluate the effect of incorporation of 0.5% wt Ag-Zn zeolite into condensation silicone through the following tests; setting time, dimensional stability, reproduction of details, wettability, and hardness . Materials and methods: one hundred specimens were constructed of condensation silicone, divided into two groups for the first 50 specimens one0.5% by wt Ag -Zn zeolite was added, keeping the other fifty sp

Study the Effect of Face Sheets Material on Strength of Sandwich Plates with Circular Hole
...Show More Authors

This study aims to investigate the effect of changing skins material on the strength of sandwich plates with circular hole when subjected to mechanical loads. Theoretical, numerical and experimental analyses are done for sandwich plates with hole and with two face sheet materials. Theoretical analysis is performed by using sandwich plate theory which depends on the first order shear deformation theory for plates subjected to tension and bending separately. Finite element method was used to analyse numerically all cases by ANSYS program.

The sandwich plates were investigated experimentally under bending and buckling load separately. The relationship between stresses and the ratio of hole diameter to plate width (d/b) are built, by

The Effect of Using Online Automated Feedback on Iraqi EFL Learners’ Writings at University Level
...Show More Authors

Feedback on students’ assignments can be done in many different ways. Nowadays, the growing number of students at universities has increased the burden on the instructors to give feedback on students’ writings quickly and efficiently. As such, new methods of modern online automated feedback tools, such as Hemingway app and ecree,are used to assist and help instructors. Hence, this research is an explanatory study to examine the effect of using the online automated feedback on some Iraqi EFL learners’ writings at the university level. The study comprised 60 students enrolled in an English language course at the University of Anbar. They were divided randomly into two groups, experi

Robust Estimation OF The Partial Regression Model Using Wavelet Thresholding
...Show More Authors

            Semi-parametric regression models have been studied in a variety of applications and scientific fields due to their high flexibility in dealing with data that has problems, as they are characterized by the ease of interpretation of the parameter part while retaining the flexibility of the non-parametric part. The response variable or explanatory variables can have outliers, and the OLS approach have the sensitivity to outliers. To address this issue, robust (resistance) methods were used, which are less sensitive in the presence of outlier values in the data. This study aims to estimate the partial regression model using the robust estimation method with the wavel
