The effect of video-based approach on prospective teachers’ ability to analyze mathematics teaching

This is an intervention study that explored the effect of using video lesson analysis methodology (VLAM) on the ability of prospective middle/high school mathematics teachers to analyze mathematics teaching. The sample of the study consisted of 26 female prospective mathematics teachers enrolled in a methods course at the United Arab Emirates University. The participants were divided equally into two groups, experimental and control. The experimental group was involved in video lesson analysis where they analyzed ten video lessons throughout the semester. The group members interacted via discussion forums through Blackboard technology. Both groups wrote analyses of two video lessons, one before the intervention program and another at the end of it. It was found that the intervention remarkably improved the ability to analyze mathematics teaching of the experimental group while little improvement occurred to the control group. Implications for teacher education programs are discussed.     

Students’ Alternative Conceptions about Electricity and Effect of Inquiry-Based Teaching Strategies

This study attempted to investigate the alternative conceptions that a group of 12 Lebanese students in a grade 9 class hold about electricity. It also attempted to evaluate learning outcomes of implementing in that class an inquiry-based module for the acquisition of conceptual understanding of basic concepts in electricity. Fourteen mostly subjective tests were administered throughout the implementation phase of the inquiry-based module to assess the evolution of participants’ conceptions. The instrument DIRECT (Version 1.0) focusing on conceptual understanding was used as a post-instructional test to measure acquisition of understanding. The findings revealed that most of the alternative conceptions reported in literature were found amongst the participants. Results of the post-testing showed that the implemented inquiry-based approach was successful in enhancing participants’ conceptual understanding of the targeted DC circuit concepts.

Creativity in science and the link to cited references: Is the creative potential of papers reflected in their cited references?

Several authors have proposed that a large number of unusual combinations of cited references in a paper point to its high creative potential (or novelty). However, it is still not clear whether the number of unusual combinations can really measure the creative potential of papers. The current study addresses this question on the basis of several case studies from the field of scientometrics. We identified some landmark papers in this field. Study subjects were the corresponding authors of these papers. We asked them where the ideas for the papers came from and which role the cited publications played. The results revealed that the creative ideas might not necessarily have been inspired by past publications. The literature seems to be important for the contextualization of the idea in the field of scientometrics. Instead, we found that creative ideas are the result of finding solutions to practical problems, result from discussions with colleagues, and profit from interdisciplinary exchange. The roots of the studied landmark papers are discussed in detail.     

How do legal surprises drive organizational attention and case resolution? An analysis of false patent marking lawsuits

Legal surprises are unexpected suits or actions in which plaintiffs rely on claims or precedents that may be obscure, unfamiliar, or unknown to the defendants. Our study explores false patent marking suits, a unique type of patent-related legal surprise involving allegations of defendants marking products with ineligible patent numbers to deceive customers and/or deter competitors. An abrupt shift in U.S. Federal Courts’ interpretation of intellectual property rights (IPRs) policy amplified plaintiff incentives for filing these suits while escalating defendant penalties for proven violations. Handling costly legal surprises such as false patent marking suits requires focused attention from managers. Our core premise is that temporal and evidential cues in the timelines and storylines of plaintiffs’ legal narratives in surprise suits attract defendants’ organizational attention. We hypothesize about temporal focus (past, present, and future) and evidentiary reasoning (relevance, credibility, and inferential power) as attention cues and possible predictors of the mode (litigation or negotiation) and timing of case resolution. We apply automated content analysis to official court records for 992 false patent marking cases (2009–2011) and quantify competing risks using hazard models. We find that differences in temporal focus and evidentiary reasoning in the legal narratives of surprise suits are significant predictors of case resolution mode and timing. We also find that defendants countersuing to redirect plaintiffs’ attention is an effective negotiating tactic. We discuss the economic significance and strategic implications of our empirical findings on legal surprises, attention, case resolution mode and timing, and the unintended consequences of IPR policy changes.     

Impact of a Brief Literacy Intervention on Urban Preschoolers

A pre-post study was conducted at an urban child-care center to study the hypothesis that a brief literacy intervention would result in improved receptive vocabulary for preschoolers. Parents attended a series of 4 workshops about reading to children. The children had a significant 7-point increase in their Peabody Picture Vocabulary Test scores at 7-month follow-up. Children of college-educated parents had a higher increase in scores than did children whose parents were not college educated.     

The PCC ISNI Pilot: Exploring Identity Management on a Global,Collaborative Scale

Abstract

The Program for Cooperative Cataloging (PCC) conducted a multi-institution Pilot project to contribute metadata to the International Standard Name Identifier (ISNI) database. In addition to describing the goals, structure, and activities undertaken in the Pilot, this article examines some of the experiences of PCC metadata practitioners as they sought to incorporate ISNIs into their metadata workflows and pursue a wide range of ISNI use cases. Lastly, the article outlines next steps that flowed from the Pilot as the PCC has parlayed its newly developing identity management expertise into additional PCC program explorations.     

The interfaculty graduate environmental sciences program of the American University of Beirut: an ESD initiative in the Arab World

The American University of Beirut’s Interfaculty Graduate Environmental Sciences Program was launched in 1997 as a means of addressing salient issues on the environment and development in Lebanon and the Arab World using an interdisciplinary approach. The programme adopts a student-centred learning approach and aims to develop critical and systems thinking skills to produce socially and environmentally conscious leaders and agents of change in the Arab World. In this paper, we provide an evaluation of the programme’s ESD dimensions using the criteria of interdisciplinarity, local relevance and competence-based learning. This is followed by a critical analysis of the programme’s potential for use as a model in the Arab World. We find that, while the model may be useful in providing inspiration and a good practice case, its transfer “as is” to institutions of higher education in the Arab World or even in Lebanon is unlikely, and perhaps undesirable, in view of the inherently diverse nature of Arab universities.     

非政府组织在天文学科普方面的作用

古代伊朗科学家曾对科学,特别是天文学做出过重大贡献。当代的伊朗科学家继承了这一传统,并致力于向公众传播科学。21世纪初,由一批科学家、热心科学传播的社会人士和私营企业组成的非政府组织积极筹建马什哈德天文馆、科学中心等科普场馆。本文通过这一案例,讨论了非政府组织在科普场馆建设和科学传播中的作用、问题和可行性,并介绍了马什哈德天文学会为此采取的相应对策。
