Perceptions of Information Literacy Skills among Undergraduate Students in the Social Media Environment

This study assessed information literacy perceptions of undergraduate students at Sultan Qaboos University in their use of social media. A quantitative approach was used to collect data from undergraduate students. The study consisted of 1,142 completed questionnaires by randomly selected participants. The results demonstrated overall moderate levels of perceptions toward the evaluation of information, information ethics, legal issues, and privacy issues. In evaluation of information, credibility of information was considered as an important factor to decide whether to use information for academic purposes. This study signifies the importance of understanding perceptions of information literacy among undergraduate students in a specific socio-cultural context. The results can also be generalized to similar academic institutions worldwide. It is also hoped that the study's findings will assist in developing contextual training programs or information literacy quizzes to promote information literacy in the social media environment.     

An outranking approach for information retrieval

Over the last three decades, research in Information Retrieval (IR) shows performance improvement when many sources of evidence are combined to produce a ranking of documents. Most current approaches assess document relevance by computing a single score which aggregates values of some attributes or criteria. They use analytic aggregation operators which either lead to a loss of valuable information, e.g., the min or lexicographic operators, or allow very bad scores on some criteria to be compensated with good ones, e.g., the weighted sum operator. Moreover, all these approaches do not handle imprecision of criterion scores. In this paper, we propose a multiple criteria framework using a new aggregation mechanism based on decision rules identifying positive and negative reasons for judging whether a document should get a better ranking than another. The resulting procedure also handles imprecision in criteria design. Experimental results are reported showing that the suggested method performs better than standard aggregation operators.     

Metacognition research and theory: Analysis and implications for instructional design

Metacognition, a construct with strong empirical and theoretical foundations, is integral to successful learning. Research on metacognition has provided convincing evidence supporting its importance in the instruction and learning processes. In this article, research on several aspects of metacognition are briefly reviewed and analyzed, examples of metacognitive strategies are provided, and implications for instructional design are described.     

Comparative education and sociological thought in the Arab region,with special reference to the work of ALECSO

This paper examines the work done in the field of comparative education in the Arab region and analyses its conceptual and theoretical assumptions. It also analyses the work done by the Arab League Educational, Cultural and Scientific Organisation (ALESCO). The author argues that there is very little influence from sociology on the comparative education research carried on in the Arab region, though there is some influence from the functionalist school. There is heavy reliance on the economics of education, especially in the work of those utilising the concept of human capital. Most of the research carried out is practice-oriented research, aiming at policy formation and the provision of factual data for policy-makers, and mainly concerned with the internal working of educational systems in the Arab region.

Zusammenfassung Dieser Artikel untersucht die auf dem Gebiet der vergleichenden Erziehungswissenschaft in der arabischen Region geleistete Arbeit und analysiert ihre konzeptuellen und theoretischen Voraussetzungen. Außerdem werden die Tätigkeiten der Educational, Cultural and Scientific Organisation der arabischen Liga (ALECSO) analysiert. Es wird festgestellt, daß die Soziologie sehr wenig Einfluß auf die vergleichende erziehungswissenschaftliche Forschung in der arabischen Region ausgeübt hat; nur die funktionalistische Schule hat sich bis zu einem gewissen Grade ausgewirkt. Starker Nachdruck liegt auf der Bildungsökonomie, vor allem in der Arbeit von Wissenschaftlern, die das Konzept menschliches Kapital benutzen. Überwiegend ist die betriebene Forschung praxis-orientiert. Ihr Ziel ist, zur Erarbeitung einer Bildungspolitik beizutragen und den Bildungspolitikern faktisches Material zu liefern. Daher befaßt sie sich hauptsächlich mit dem internen Erziehungswesen der betreffenden Länder in der arabischen Region.

Résumé Cet article examine le travail effectué dans le domaine de l'éducation comparée dans les Etats arabes et analyse ses présomptions conceptuelles et théoriques ainsi que le travail de l'Organisation Arabe pour l'Education, la Culture et la Science (ALECSO). L'auteur soutient que la sociologie n'exerce qu'une influence très restreinte sur la recherche concernant l'éducation comparée menée dans les Etats arabes, quoique l'on y constate une certaine influence de l'école fonctionnelle. On place une grande confiance dans l'économie de l'éducation, surtout dans le travail de ceux qui utilisent le concept de capital humain. La majeure partie de la recherche est orientée vers la pratique, visant à l'élaboration d'une politique d'action, à la fourniture de données factuelles aux décisionnaires, et elle s'intéresse surtout au travail interne des systèmes d'éducation dans les Etats arabes.

     

Toward Educational Requirements Model for Mobile Learning Development and Adoption in Higher Education

Mobile learning (M-learning) is a learning paradigm that utilizes the advantages of mobility and wireless technologies in the learning and education process. It can be characterized by the ability to support and provide strong interaction between learners and instructors, offering high levels of learning motivation, collaboration, and flexibility to the learning activities. Despite the increased popularity of M-learning, there is no complete and well-defined set of educational requirements for M-learning in higher education which considers both instructional design and M-learning design. Therefore, this paper proposes a new educational requirements model for M-learning development and adoption in higher education. This set of requirements has been built from a literature study with focus on standards for learning and mobile application software quality and guidelines. This work presents the results of applying the proposed set of educational requirements on three different M-learning systems. Instructional designers and educational software developers may find the requirements useful in the development of M-learning systems. The effort described is part of an Omani-funded research project investigating the development, adoption and dissemination of M-learning in Oman.     

Engaging Actively with Issues in the Responsible Conduct of Science: Lessons from International Efforts Are Relevant for Undergraduate Education in the United States

Numerous studies are demonstrating that engaging undergraduate students in original research can improve their achievement in the science, technology, engineering, and mathematics (STEM) fields and increase the likelihood that some of them will decide to pursue careers in these disciplines. Associated with this increased prominence of research in the undergraduate curriculum are greater expectations from funders, colleges, and universities that faculty mentors will help those students, along with their graduate students and postdoctoral fellows, develop an understanding and sense of personal and collective obligation for responsible conduct of science (RCS). This Feature describes an ongoing National Research Council (NRC) project and a recent report about educating faculty members in culturally diverse settings (Middle East/North Africa and Asia) to employ active-learning strategies to engage their students and colleagues deeply in issues related to RCS. The NRC report describes the first phase of this project, which took place in Aqaba and Amman, Jordan, in September 2012 and April 2013, respectively. Here we highlight the findings from that report and our subsequent experience with a similar interactive institute in Kuala Lumpur, Malaysia. Our work provides insights and perspectives for faculty members in the United States as they engage undergraduate and graduate students, as well as postdoctoral fellows, to help them better understand the intricacies of and connections among various components of RCS. Further, our experiences can provide insights for those who may wish to establish “train-the-trainer” programs at their home institutions.     

Optimizing Instructional Video for Preservice Teachers in an Online Technology Integration Course

This study assessed the effect of design instructional video based on the Cognitive Theory of Multimedia Learning by applying segmentation and signaling on the learning outcome of students in an online technology integration course. The study assessed the correlation between students’ personal preferences (preferred learning styles and area of specialization) and their learning outcomes. A three-group pretest–posttest design was employed to assess whether there were significant differences in students’ test scores after they watched an instructional video. The results of the analysis of covariance (ANCOVA) analysis indicate that instructional design had a significant effect on students’ learning outcome. This effect was demonstrated by the statistically significant differences in students’ learning outcomes, with the highest scores achieved by students in the segmented and signaled video group and the lowest scores in the no-segmentation and no-signaling group. Moreover, results indicate that students’ learning preferences and area of specialization related significantly and positively to their learning outcomes. These findings suggest that the use of educational video in online courses has the potential to effectively improve students’ learning outcome; however, it requires design manipulation. The results also emphasize the importance of rethinking the one-size-fits-all approach in developing online course content and include consideration of the students’ learning preferences and area of specialization to optimize their learning.     

Study on Urinary Candidate Metabolome for the Early Detection of Breast Cancer

A metabolomic study for determination of certain urinary metabolomes, 1-methyladenosine (1-MA), 1-methylguanosine (1-MG), and 8-hydroxy-2′ deoxyguanosine (8-OHdG) in urine specimens of breast cancer patients. The accuracy of these metabolites and their combined score with cancer antigen 15-3 (CA15-3) was developed to improve the early detection of breast cancer. This study recruited 52 healthy individuals, 47 benign breast tumors, and 167 malignant breast tumor patients. Urine samples were handled to adjust the creatinine concentrations to 8 mg/dL (0.7 mmol/L) and analyzed using GC–MS to detect and quantify the selected urinary metabolomes in urine samples of all participants. The accuracy of individual urinary metabolomes and their combination with CA15-3 were evaluated using multivariate statistical analysis. The cutoff value of CA15-3 was 32.5 U/mL. Cutoff values of 1-MA, 1-MG, and 8-OHdG were 2.19, 2.1, and 7.3 µmol/mmol creatinine, respectively. The concentrations of 1-MA, 1-MG, and 8-OHdG were significantly higher in breast cancer patients, especially in the early-stage. The combination of three urinary metabolomes with CA15-3 improves the diagnostic sensitivity of breast cancer. For the combined score, the area under the curve (AUC) value of combined score ranged from 0.820 to 0.950, with high accuracy, ranged from 77.0 to 95.5%. The most significant AUC (0.973), sensitivity (90.1%), selectivity (94.0%) was recorded at comparing the healthy control with the early-stage of malignant breast cancer. In conclusion, the combination of three urinary metabolomes with serum CA15-3 improves the diagnostic sensitivity of breast cancer.
