Spectrophotometric determination of iron in dietary supplements in Libyan market
In most cases dietary supplements especially in Libya are consumed without prescriptions and
the public has very limited any awareness of their health risk. The lack of quality control on
numerous brands of dietary supplements in pharmacies of Libya today may result in a serious
The aim of this study is to determine the iron content using a fast and accurate method for quality
control of some imported dietary supplements, based on spectrophotometric measurement of iron
after complexation with 1, 10-phenanthroline in an acidic medium. Eight types of vitamin
supplementary tablets were randomly collected from the Libyan market and analyzed for the iron
content. The analysis showed an average value of 61mg Fe/pill for the range of 40.07-112.63 mg
Fe/pill. Results showed that 75% of the samples were lower in iron content than that recorded on
the dietary products. arabic 9 English 71 ezuldeen mohammed abraheem aboushalloua(1-2020)
Facebook Games for English Language Learning: What Student-Teachers Say?
This exploratory case study aimed at investigating the student-teachers’ views on using Facebook games for language learning. The participants were 48 student-teachers at the EFL Department of the Faculty of Education at a Libyan public university. They were required to play Facebook games for two weeks and then present their experiences through oral presentations and reflective journals. Data were collected through student-teachers’ presentations and reflective journals. Data were analyzed qualitatively using a thematic inductive approach. Although few student-teachers had negative views, most of the student-teachers had positive views on using Facebook games for learning. They believed that Facebook games teach players following instructions and provide opportunities for language improvement, especially for vocabulary learning. We expect that our findings would provide teachers and practitioners with ideas for classroom research and encourage researchers to conduct further and more rigorous testing on integrating Facebook games into the EFL classroom. arabic 12 English 61 Entisar ALi Hadi Elsherif, fatma alhammali ali dreid(2-2021)
Judging the Judges: Examining Supervisors Assessment of Unobservable Skills in Developed EFL Teaching Practice Model.
This qualitative descriptive case study reflects the researcher's experience, as a Teaching Practice (TP) Co-ordinator at the Libyan Faculty of Education Tripoli (FET), in developing and examining academic supervisors’ implementation of an innovative TP Assessment Model for EFL trainees. Previous assessment lacked accuracy and comprehensiveness and relied solely on assessing behavioural observable skills. The new TPAM incorporates, for the first time at FET, Unobservable Skills Assessment through supporting documents that supervisors use to assess trainees’ skills in classroom observation, feedback provision, self-reflection, and reporting on TP experience, all of which comprise a Teaching Practice Portfolio (TPP). The study focuses on a key concern: (1) How to develop existing assessment criteria in an objective and comprehensive manner embracing both observable and unobservable skills. Two operational sub-questions emerged: (2) How would the supervisors’ implement the Unobservable Skills Assessment in the TPAM; (3) How would trainees respond to Unobservable Skills Assessment criteria? Data were collected through quantitative analysis of the supporting documents; semi-structured interviews with seven supervisors involved; focus group discussions with trainee teachers. The findings show that while the supervisors were satisfied with the developed assessment criteria, their overall performance in implementing the Unobservable Skills Assessment was poor; besides a lack of immediate feedback provision after school visits, the supporting documents for unobservable skills were not fully executed. Only two supervisors out of seven demonstrated acceptable adherence to the model requirements. Some trainees had reservations regarding the extra workload required in carrying out self-reflections and in writing reports of TP experience; others considered the criterion of professional development outlook inconsequential during initial teacher training. arabic 16 English 101 ٌٌReda Khaled Emhemmed Elmabruk(1-2020)
