The Impact of the different methods of Selecting One Group in Calculating the Items Sensitivity Coefficient on the Standard Characteristics of the Criterion-Referenced Test
...Show More Authors

AbstractThe research aims to identify the impact of the different methods in calculating the Items sensitivity coefficient on the standard characteristics of the Criterion-Referenced test in the measurement and evaluation material. The research sample consisted of (35) male and female students, who were chosen by the intentional method. The researcher prepared learning-teaching program in constructing the content of the measurement and evaluation material for non-specialized departments, prepared an achievement test in its equivalent forms, identified the results of agreement between the methods used in analyzing the items of the criterion-referenced test, and compared the standard characteristics of the achievement test, both according to the six methods used, which depend on one group. The researcher adopted a number of statistical methods, and after analyzing the data, the results showed that the most convergent methods for selecting items are (Cox and Vargas -reference compatibility –Brennan discrimination and Roudabush). There are statistically significant differences between the methods used in calculating the index coefficient of the items sensitivity on the characteristic of validity, and in order to identify the significance of the differences between the reliability coefficients according to the different methods of items analysis, the researcher used the ZTest equation to infer about the method’s preference and its effect on the reliability coefficient, by comparing the calculated Z-values with the tabular value at the significance level (0.05) and amounting to (1.96) to calculate the significance of the differences in the correlation coefficients. It was found that through all the calculated values for Z, they are not significant, which means that there are no statistically significant differences between each of (Cox and Vargas coefficient, reference compatibility coefficient, Phi coefficient, binary correlation coefficient, discrimination coefficient B (Brennan), and the coefficient of Roudabush to calculate index coefficient of the items sensitivity in its impact on the reliability of the achievement test, and the research showed a number of recommendations and suggestions..

Phenol Removal Using Granular Dead Anaerobic Sludge Permeable Reactive Barrier in a Simulated Groundwater Pilot Plant
...Show More Authors

This study investigates the performance of granular dead anaerobic sludge (GDAS) bio-sorbent as permeable reactive barrier in removing phenol from a simulated contaminated shallow groundwater. Batch tests have been performed to characterize the equilibrium sorption properties of the GDAS and sandy soil in phenol-containing aqueous solutions. The results of GDAS tests proved that the best values of operating parameters, which achieve the maximum removal efficiency of phenol (=85%), at equilibrium contact time (=3 hr), initial pH of the solution (=5), initial phenol concentration (=50 mg/l), GDAS dosage (=0.5 g/100 ml), and agitation speed (=250 rpm). Fourier transform infrared (FTIR) analysis proved that the carboxylic acid, aromatic, alk

Exposure and its working mechanisms in theatrical multi-scene model "critical dramaturgy study": يوسف رشيد جبر
...Show More Authors

The concept of intertextuality was one of the problems that occupied the attention of critics and critics in targeting the structure of textual intertextuality between texts and their overlap in the process of producing meaning. Until intertextuality became a stable term and it can be monitored in the structure of the theatrical text and determining the mechanisms of this intertextuality between texts through fields and classifications agreed upon by the most important critics who wrote and considered intertextuality. Perhaps our previous research (the approach of exposure in the epistemological hallway to intertextuality) was an attempt to interview a terminology, which the researcher intended to monitor, through the mechanisms of inter
