The Impact of Raising Phonological Awareness on Improving EFL Learners Reading Comprehension: A Case Study at Preparatory Year Najran University (Published)
The study utilized experimental and descriptive approach to identify the impact of raising phonological awareness on improving EFL reading comprehension skill among Preparatory Year students at Najran University (NU). Phonological Awareness is an applied linguistic term which refers to the ability to hear and manipulate the sound structure of language. It is an encompassing term that involves working with the sounds of language at the word, syllable, and phoneme level and contains many processes. The study is an attempt to identify the impact of phonological awareness training and gender on reading performance of preparatory year students at NU. The sample consisted of (160) students, (80) males and (80) females. Phonological Awareness Skills Test and Cronbach Alpha Coefficient utilized to measure progress in four phonological awareness skills including word identification, word deletion, word blending and word rhyming while a reading passage. Pre- and post-Cloze Test applied to identify the reading levels of the participants. In addition, simple percentage and T-Test utilized to statically analyze the data. The results revealed that training on phonological awareness skills significantly improved the reading performance of the students in the experimental group.
The present study aimed to identify the requirements and criteria of instructional design of e-courses in addition to what degree faculty members are familiar with such skills and requirements. It also sought to identify the most important visions for the development and design of e-courses from the perspectives of experts and faculty members besides the main obstacles that face them during the design process. The descriptive approach was used to carry out the study. The questionnaire is a main study tool used for data gathering. A sample of (101) was randomly selected out of the faculty members at the College of Education and the College of Science and Arts was randomly selected. Findings indicated that there were certain criteria and requirements for the instructional design of the e-courses that faculty members should refer to in order to obtain a suitable e-content. There were significant differences between the faculty members’ degree of knowledge and degree of use in favor of their knowledge degree of the instructional design skills. Furthermore, their knowledge degree was moderate and their use degree was low. Results also showed that there were certain obstacles facing faculty members while developing their e-courses. The most prominent obstacles were the lack of enough training workshops for the basics of e-courses design and development in addition to the lack of e-laboratories for training on the primary development of e-courses. The most important visions provided by faculty members were the development of faculty members’ skills of the e-courses design via specific straining workshops besides following quality international criteria when they design and develop e-courses.
Chemical and Technological Studies of Mango Seed Kernel (Published)
Abstract: The present study aimed to benefit from the flour of mango kernels in the preparation of biscuits after some industrial processing operations to reduce kernels’ content of tannins. Nutritional value of the flour of mango kernels and wheat and prepared biscuits by replacing 10%, 20%, 30%, 40% and 50% of wheat flour by the flour of mango kernels. Results showed that the content of the flour of mango kernels of raw fat was 12.39% and the ratio of unsaturated fatty acids was 55.3%. Results also revealed that by increasing replacement proportion the content of biscuits of fibers, ash and fats increased while its content of proteins and carbohydrates decreased. Sensory properties of biscuits also improved by increasing the replacement proportion until 40%. Thus, the results confirm that the use of the flour of mango kernels as an alternative for wheat flour, with 40% of replacement, in the preparation of biscuits improves the nutritional value and quality of biscuits.
