   Thsst researcher problem of delays faced by researchers are all waiting to evaluate their standards by the experts who must take their views to extract the truth Virtual important step first step in building standards whatsoever, then the difference of opinion among experts about the paragraphs Whatever the scope of their functions, leading to confusion in maintaining these paragraphs or delete? Or ignore the views and opinion of the researcher to maintain the same? Or as agreed upon with the supervisor if he was a student? Especially if the concepts of a modern new building.
   Therefore, the researcher sought to try to find a solution to her problem to conduct an experiment to test building steps Kdharurat basic standards are supported in building operations, such as the experience of logical analysis to extract the virtual honesty, and check how to utilize them, and are indispensable as possible in general? Or there may be exceptions to the standards or in the selection of experts? Comparing the results of this step the results of experiments and global statistical analysis as steps again, and then select any of these steps or tests relied upon in the final results for the construction of standards? According to the procedures for each of them and the fact that the results and accuracy in achieving the most important thing required of the building measures concepts which are honesty (Validity), which we are looking for from the outset of the construction process in order to answer the question: Is designed scale to measure really is set up to in order to measure? And to any extent?
   The researcher identified three tools standards for test construction Eventually, she concluded to the following results:
   Despite the different theoretical concepts measured by these tools and the number of paragraphs and samples, they are among the measures of foreign Ptarevadtha and components, construction and samples, and the scale of a local definition and its components and the construction and appointed, they were similar results of experiments logical analysis to extract the truth Virtual them in the fact that experiments were superficial includes amendments to the most grammatical and linguistically, they are not deleted, but two paragraphs only, out of the preparation of the paragraphs of three measures the amount of (58) paragraph to the measure of emotional intelligence, and (24) paragraph to the measure of social cohesion, and (90) a paragraph to measure hardness psychological, respectively, one of them repeatedly to reveal the true response, The second dialectic, despite differences in people submitted to them standards, both in experience or general jurisdiction flour, while the varied results of experiments statistical analysis and global, including the scale retained Pfaqrath all of the standards has reduced its paragraphs by almost half, it is out (58), and (24) , and (90) paragraph, became (44), and (24), and (46) paragraph, respectively, Besagha final. Which makes us pause and reflect on the hopes of these results, especially if we were sure of the validity of statistical procedures used in the construction of these standards, and we have to ask ourselves:
Q / we will rely on any results in the form of the final version of these standards?
Q / Can we rely on the results of logical analysis to extract the virtual honesty? ((It was originally believed superficial virtual shows what appears and what appears externally to the scale that measured, which is believed influenced the verdicts of self for people who depend on them to extract what is built on the self and the subjective opinions away inevitably for objectivity and accuracy, and most modifications grammatical, linguistic, or they just make a The delay of the words, they were not in the meaning and the formulation and the level of the paragraph, and with some careful review them between the researcher and the supervisor and an expert linguist and specialist in measurement corrected with ease the time and effort much less than if presented to several people and all the Laidlaw Bajtahadeh Profile)).
 Q / or rely on the results of statistical analysis and to extract the global structural real truth? ((These results are accurate statistical and experimental shows real roots of the underlying concepts and explain the links strong between the components of the original of the content of the paragraphs of standards of the links weak, however change the number of paragraphs or was reduced, the results did not keep the number of items as it is, which makes the researcher at a loss to act against them. Do you keep the paragraphs prepared by the concept of fatigue and trouble and consulted from able to extract the truth virtual, and all made will intervene? M depends on the results of statistical analysis and global specifically? which is the final step and the most accurate in the detection of links between the paragraphs and their assets and being the measure really is designed so as to measure only and does not nothing else, and settled the final number of paragraphs of standards researched? .... Q / M depends on what?
   Here will stand any scientific researcher in front of these results may say to himself, "So why this delay in the work and procedures, and why all this fatigue and suffering in wasting time, effort and money, is not it better for a statistical work and global, and give him the time and effort and all the money, because its results are more accurate is adopted in the construction, Valbagesan always conducting experiments as steps are all essential building credit, but they take their final results only "
Finally, the researcher recommends that all those involved in this scientific topic, taking these results and the adoption of these measures substitute for the first step in building standards in order to achieve scientific accuracy and save time, effort, money and effort.
The researcher proposes to prepare a brochure special steps to prepare and build paragraphs of psychometric assessment includes all of the observations that can help researchers in the preparation and drafting of the paragraphs of minutes do not require modifications of any kind to measure the concepts that are prepared in order to measure and nothing else.

The Effect of Combining Video Lectures and Kolb Experiential Learning on EFL Student-Teachers’ Ability to Teach Communicative Coursebook and their Teaching Competencies
...Show More Authors

Communicative-based textbooks are developed and disseminated throughout the country.
However, it is difficult for teachers who themselves have learnt English through the traditional
approaches to suddenly be familiar with CLT (Communicative Language Teaching) principles
and teach communicatively. Therefore, many teachers remain somewhat confused about what
exactly CLT is and others familiar with CLT but unable to achieve communicative classroom
teaching. Consequently, those teachers need to be introduced to the CLT principles and they need
training in how to put CLT principles into practice. Accordingly, this study aims to find out the
effect of combining video lectures and Kolb experiential learning on EFL student-t
