The effect of video-based approach on prospective teachers’ ability to analyze mathematics teaching 总被引:1,自引:0,他引:1
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. 相似文献

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. 相似文献

One of the factors that affect the parameters of an underground cable is earth return path impedance. Pollaczek developed a formula for the case of one-layer (homogenous) earth. But in practice the earth is composed of several layers. In this study we develop a new formula for earth return path impedance in the case of a three-layer earth. To check the accuracy of the obtained results, a comparison has been made with the finite element method (FEM). A comparison between the results of the Pollaczek formula and results of the obtained formula for a three-layer earth has been made, showing that the use of the Pollaczek formula instead of the actual formula can cause serious errors. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

AbstractThe 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. 相似文献

This research aimed at developing a methodological framework to investigate the alignment of the Lebanese national math exam tests with the curriculum at the middle school level, during the transitory period of a major curricular reform. The focus is on exploring the characteristics of an “assessment culture” set by the national exams during the long life of the old curriculum. A framework for analyzing non-objective type tests is developed and piloted. The study considered a sample of 3 model tests reflecting the analyzed curriculum, and 11 official exam tests administered over the last 6 years of its life. The 2 sets of exams were analyzed and compared. It was found that the official tests have a stable structure in format and in content, and involve a limited set of topics that determine a “mini-curriculum”. The results showed discrepancies between the official and the model tests, indicating lack of alignment. 相似文献
