(2017). Transforming Educational Practices of Ethiopia into Development and the Knowledge Society through Information and Communication Technology. African Educational Research Journal, v5 n1 p1-17 Jan. Despite the improvements in the access to and use of information and communication technology (ICT) around the world, there is evidence which suggest that a persistent digital divide between and within countries. ICT increases the flexibility of delivery of education so that learners can access knowledge anytime and from anywhere. It can influence the way students are taught and how they learn as now the processes are learner driven and not by teachers. This in turn would better prepare the learners for lifelong learning as well as to improve the quality of learning. It can improve the quality of teaching-learning and thus contribute to the development of Ethiopia. Nowhere is the ICT gap more evident than in the education system and practices. This study assesses ICTs in supporting educational practices of Ethiopia for transforming into a knowledge- and information-based society and economy. It also focus on the benefits that ICT integration in education system can provide, right… [PDF]

(2009). The Chancellor's Role in a Presidential Transition. Presidency, v12 n1 p30-32, 34 Win. Successful transitions involving a formal role for the former president, such as chancellor, are rare enough that the authors think theirs is an exceptional experience and is worth sharing, especially given the bulge of presidential retirements anticipated over the next decade. The authors believe that this model of transition can be successful, but only if fairly stringent conditions are met. Can a former president stay on as chancellor without crossing leadership swords with his successor? The authors draw from their own unique–and successful–transition experience and present a case study of one presidential transition. (Contains 4 notes.)… [Direct]
(2009). Taking Your Library on the Road. Computers in Libraries, v29 n5 p12-15 May. Information professionals need to be reachable through email (through cell phones, laptops, Treos, and BlackBerries) and customers' questions have to be answered in \real time,\ meaning that once the question is sent, an answer is expected that moment. A library in a Google environment allows this to happen. It also allows the information professional to be available 24/7, the documents to be obtainable 24/7, and online sharing and discussion between customers and the information professional to be possible. In this article, the author describes the steps in making an electronic library assistant (ELA) within a sandbox environment in Google. Through these steps, information professionals can have an ELA to help them with their duties while they travel all over the world–or at least all over town. All they need is a laptop.

(2010). Quality's Higher Education Dividends: Broadened Custodianship and Global Public Scholarship. Quality in Higher Education, v16 n2 p163-167 Jul. This paper speculates on the possible contribution of the quality movement to higher education and the perceived dividends received from this, in general, over the past two decades but also, more specifically, with reference to the author's institution in South Africa. The first major quality contribution is a gradual broadening of higher education custodianship, ensuring that academic provision more closely resembles societal expectations. It is hoped that the dividend stemming from this will be renewed public trust in higher education. The quality movement put public scholarship globally into action via its tested strategies of self-reflection, interrogation, assessment and, especially, via the airing, sharing and exchange of research findings and practices that work. This scholarship, which increasingly contributes to the integration of various higher education subsystems and which is also respectful of contextual difference and institutional identity, is perhaps the quality… [Direct]
(2010). Community-Based Individual Knowledge Construction in the Classroom: A Process-Oriented Account. Journal of Computer Assisted Learning, v26 n3 p202-213 Jun. This paper explores the process of knowledge convergence and knowledge sharing in the context of classroom collaboration in which students do a group learning activity mediated by a generic representation tool. In analysing the transcript of the interactions of a group, we adapt the group cognition method of Stahl and the uptake analysis methodology of Suthers to understand how the members of the group did meaning making in their interactions, and how individual members did uptakes of their interactions and applied their new shared knowledge or understanding in new situations. The transcript is taken from our school-based research using the Group Scribbles software technology which provides representation spaces for individual, group or class work to support collaborative practices. Our work contributes toward a methodology for explaining a process-oriented account of a small group interaction through face-to-face communication over external shared representations…. [Direct]
(2012). An Exploration of How Elementary School Principals Approach the Student Retention Decision Process. ProQuest LLC, Ed.D. Dissertation, The George Washington University. This is a constructivist grounded theory study investigating how elementary principals approach the student retention decision process in their schools. Twenty-two elementary principals participated in the study using a selective or snowball sampling method. Principals worked in one of three districts in a mid-Atlantic state and had experience as educators ranging from 15 to 45 years. The researcher conducted semi-structured interviews lasting between 60 and 90 minutes over a 4-month period. Student retention documents and handouts collected during interviews provided supporting evidence for how principals approach the student retention decision process. Participants answered follow up questions to clarify holes in the data and ensure that the researcher fully understood what participants were sharing. Results indicated that elementary principals' beliefs and experiences inform how they approach student retention decisions. Principals had strong beliefs about the time of the… [Direct]
(2012). Leaving the Well-Rutted Contours of My Pedagogical Past. Teaching English in the Two-Year College, v39 n3 p306-308 Mar. This article questions educators' reliance on textbooks through the author's own struggles to come to terms with his ambiguous, sometimes frustrating, relationship with textbooks. Seeing the wide-open white pages on his syllabus and schedule, not filled or structured by a textbook, the author realizes he has an opportunity to reconsider his pedagogical landscape. Quickly he recognizes how many ideas he has meant to implement over the years, but never fully implemented because he had to cover the textbook: sharing with students his favorite writing examples, having students write during class, using student writing to illustrate rhetorical principles, and inviting students to find and evaluate materials for use in the course. The author argues that textbooks are merely tools that he has sometimes given too much power. As Robert J. Connors argues in \Textbooks and the Evolution of the Discipline,\ educators must keep \training teachers to stand by themselves . . . re-invent[ing]… [Direct]
(2013). Optimal Near-Hitless Network Failure Recovery Using Diversity Coding. ProQuest LLC, Ph.D. Dissertation, University of California, Irvine. Link failures in wide area networks are common and cause significant data losses. Mesh-based protection schemes offer high capacity efficiency but they are slow, require complex signaling, and instable. Diversity coding is a proactive coding-based recovery technique which offers near-hitless (sub-ms) restoration with a competitive spare capacity requirement with respect to other techniques. In this thesis, an optimal algorithm is developed for pre-provisioning of the static traffic using both systematic and non-systematic diversity coding. A Mixed Integer Programming (MIP) formulation is developed for systematic diversity coding which requires many fewer integer variables and constraints than similar optimal coding-based formulations. In all scenarios, diversity coding results in smaller restoration time, higher transmission integrity, and much reduced signaling complexity than the existing techniques in the literature at the expense of slightly lower capacity efficiency than Shared… [Direct]
(2009). Administrators Confront Student \Sexting\. Education Digest: Essential Readings Condensed for Quick Review, v75 n3 p13-16 Nov. Cellphone-savvy students have created instructional and disciplinary challenges for educators for years. But the recent emergence of \sexting\ by adolescents over their mobile phones caught many school administrators off guard, and the practice is prompting efforts around the country to craft policy responses. Students' sharing of nude or otherwise sexually provocative photos of themselves or classmates via messages over digital devices might be dismissed as just the latest fad in out-of-school adolescent expression–or be deemed the criminal distribution of child pornography. As sexting has grabbed public attention, and teenagers and educators have gotten caught up in the legal and other consequences of the practice, school officials have been urged to respond with more precise rules around cellphone use. They have also been encouraged to provide information to students, teachers, and parents about the dangers of sexting, including the permanent digital record it creates…. [Direct]
(2012). Surreptitious, Evolving and Participative Ontology Development: An End-User Oriented Ontology Development Methodology. ProQuest LLC, Ph.D. Dissertation, University of Maryland, Baltimore County. Ontology not only is considered to be the backbone of the semantic web but also plays a significant role in distributed and heterogeneous information systems. However, ontology still faces limited application and adoption to date. One of the major problems is that prevailing engineering-oriented methodologies for building ontologies do not actively involve end-users but instead rely on a small group of domain experts, which presents barriers to both knowledge elicitation and knowledge sharing. Based on an extensive and critical review of extant ontology development methodologies, a number of issues are identified that could hinder the involvement of end-users in the ontology development process. To address these issues, a surreptitious ontology development methodology is proposed in the dissertation. Based on the result of a usability study, the methodology is refined and a prototype system is developed to implement the methodology. Moreover, a theoretical model is built to predict… [Direct]
(2012). The UNSIN Project: Exploring the Molecular Physiology of Sins. Advances in Physiology Education, v36 n1 p13-19 Mar. Although active learning works, promoting it in large undergraduate science classes is difficult. Here, three students (F. Naji, L. Salci, and G. Hoit) join their teacher (P. K. Rangachari) in describing one such attempt. Two cohorts in a first-year undergraduate biology course explored the molecular underpinnings of human misbehavior. Students were divided into 18 groups and randomly allotted to deal with one of the four deadly sins: sloth, gluttony, lust, and wrath. Students were expected to read primary sources to devise molecular ways to counter these sins. Group progress was monitored over the 12-wk period by the preceptor (P. K. Rangachari) at scheduled intervals. A single randomly selected student was questioned about the work done, and future directions were provided by the preceptor. At the end of the term, randomly selected students defended their group's approaches to the entire class. A final written report was graded. The following multiple target molecules were… [Direct]
(2012). Parent to Parent: Giftedness with a Twist. Parenting for High Potential, v1 n5 p12-13 Mar. Discovering that a child is gifted can be both exhilarating and daunting. Parents watch in amazement and awe as their 3-year-old reads a first-grade-level book flawlessly, or they might listen to their preschool child's distress over seeing a homeless person on the street. Parents observe as their 6-year-old dismantles a broken CD player and returns it to working order, or they realize that their child's artistic talents are far above those of their peers. Parents of gifted children remember with fondness the times when their child has astonished them with an unusual talent or gift. However, most parents do not bask in the glow of their children's successes long before they realize that with this amazing gift also comes the challenge of supporting it. Initially, the wonder can be overcome by the challenge of assuring that the child reaches his or her full potential. In this article, the author takes this discovery of an unusual talent or gift and gives it the added twist of a… [Direct]
(2012). The Development of Team Trust over Time and Its Effect on Performance When Using Michaelsen's Team-Based Learning. ProQuest LLC, Ph.D. Dissertation, Iowa State University. Proponents of Michaelsen's Team-Based Learning (TBL) have claimed this teaching method quickly produces highly effective teams which are characterized by high trust among team members. Presumably, the high trust boosts performance because members feel less inhibited during discussions involving sharing personal views and challenging others' views. These team interactions can determine how well teams utilize their members' intellectual resources and make decisions. These assertions, while logical and compelling, did not appear to be fully verified within the TBL literature. This exploratory study used mixed qualitative and quantitative methods to describe performance, trust and behavior patterns over time within TBL teams in a second-year veterinary medical course. No variables were experimentally manipulated. Throughout the semester, I measured performance using students' individual and group quiz scores and measured trust using students' responses to custom… [Direct]
(2011). A Workflow for Learning Objects Lifecycle and Reuse: Towards Evaluating Cost Effective Reuse. Educational Technology & Society, v14 n4 p64-76. Over the last decade Learning Objects (LOs) have gained a lot of attention as a common format for developing and sharing digital educational content in the field of technology-enhanced learning. The main advantage of LOs is considered to be their potential for component-based reuse in different learning settings supporting different learning activities. However, despite the importance of the concept of reuse and its potential benefits in digital educational content production and deployment, there are only sporadic efforts to study issues related to LOs reuse that would allow interested parties (such as people, organizations and initiatives) to assess the conditions for and eventually implement systematic LOs reuse within the context of learning activities design and development. This is a drawback in adopting the LOs paradigm towards reducing costs and effort. In this paper, we study existing efforts for the definition of the different steps involved during the LOs lifecycle, we… [PDF]
