Development and Validation of Mathematics Achievement Test using Rasch - Bok av Taiwo Aliyu - Häftad

Development and Validation of Mathematics Achievement Test using Rasch - Bok av Taiwo Aliyu - Häftad

This study centres on the development and validation of Mathematics Achievement Test using the Rasch model. The scales used to measure achievement test in Nigeria rely on classical test theory (CTT) approach. As a result of this, they are faced with some challenges like, poor precision, sample dependence and undue focus on aggregate scores that deny test developers the opportunity of determining how the examinees performed on a test item. This problem was overcome with the application of item response..

Utilization of Synthetic Hexaploids for Wheat Improvement - Part I - Bok av Hadi Bux, Alvina G Kazi, m.fl. - Häftad

Utilization of Synthetic Hexaploids for Wheat Improvement - Part I - Bok av Hadi Bux, Alvina G Kazi, m.fl. - Häftad

Wheat (Triticum aestivum) being an important cereal crop feeds the human population worldwide. Lower genetic diversity in wheat resulted in its vulnerability to multiple biotic and abiotic constraints affecting the yield considerably. To improve its productivity, genetic improvement is needed. In order to enhance its genetic base wild ancestors of wheat have been explored and found valuable to achieve the pressing end. Amphiploids and Synthetic Hexaploids produced through crossing Durum Wheat (2n=4x=28;..

Evaluation of Chromogenic VRE medium versus Vancomycin E test - Bok av Samar Eissa, Sanaa Zaki, m.fl. - Häftad

Evaluation of Chromogenic VRE medium versus Vancomycin E test - Bok av Samar Eissa, Sanaa Zaki, m.fl. - Häftad

Chromogenic VRE medium is a simple direct effective method in detection of VRE in comparison to other techniques as E test. It is rapid and can be done directly from specimen. Our research aimed to provide scientists a new rapid technique for rapid detection of VRE as VRE is an emerging health care problem in hospitals. We hope from our work to provide a simple effective test also for typing of VRE
