We designed Knowledge Integration Environment (KIE) debate projects to take advantage of internet resources and promote student understanding of science. Design decisions were guided by the Scaffolded Knowledge Integration instructional framework. We report on design studies that test and elaborate on our instructional framework. Our learning studies assess the arguments students construct using the Knowledge Integration Environment debate project about light propagation and, explore the relationship between students' views of the nature of science and argument construction. We examine how students use evidence, determine when they add further ideas and claims and measure progress in understanding light propagation. To a modeate degree, students' views of the nature of science align with the quality of the arguments. 相似文献

This article outlines BPRS funded investigations into my own school's and other establishments' practices and processes within data analysis, needs identification and tracking of children's academic progress. It describes the evaluation of my school's then current practices and policies and the use of questionnaires and semi-structured interviews with my own staff, and assessment coordinators and senior leaders within exemplar schools. As well as outlining the main findings of my research this article assesses the introduction of new models of assessment for my own staff and pupils. This article also highlights how my research developed and the way my research process changed as it continued. 相似文献

Background: Within NHS North West England there are 24 primary care trusts (PCTs), all with access to different types of library services. This study aims to evaluate the impact the type of library service has on online resource usage. Methodology: We conducted a large‐scale retrospective quantitative study across all PCT staff in NHS NW England using Athens sessions log data. We studied the Athens log usage of 30 381 staff, with 8273 active Athens accounts and 100 599 sessions from 1 January 2007 to 31 December 2007. Results: In 2007, PCTs with outreach librarians achieved 43% penetration of staff with active Athens accounts compared with PCTs with their own library service (28.23%); PCTs with service level agreements (SLAs) with acute hospital library services (22.5%) and with no library service (19.68%). This pattern was also observed when we looked at the average number of Athens user sessions per person, and usage of Dialog Datastar databases and Proquest full text journal collections. Discussion: Our findings have shown a correlation of e‐resource usage and type of library service. Outreach librarians have proved to be an efficient model for promoting and driving up resources usage. PCTs with no library service have shown the lowest level of resource usage. 相似文献

There is currently widespread interest in exploring the opportunities to develop learning that can be delivered in three-dimensional multiuser virtual environments (3-D MUVEs). In this paper, I argue for the need to conduct research into the emerging cultures of use in 3-D MUVEs, focussing on the example of Second Life. Drawing on social and cultural studies of 3-D MUVEs, the paper briefly explores four issues in Second Life which have profound implications for the transplanting of learning: (1) the emerging 'virtual vernacular' of Second Life builds, (2) the development of a capitalist economy within and beyond Second Life, (3) the phenomenon of 'griefing', and (4) the need to take account of the everydayness of Second Life. Only by attending to the cultures of use in 3-D MUVEs—learning from Second Life—can we begin to contemplate the potential for learning in Second Life. 相似文献

To investigate the influence of an innovative math fluency intervention, 36 middle‐school students were randomly assigned to either an experimental (the Detect, Practice, Repair [DPR]) or control condition (reading intervention). After covarying pretest scores, the DPR treatment produced a significantly higher (p = .016) adjusted mean (M) math score (M = 47.53, standard deviation [SD] = 3.26) for the intervention group when compared to the control group (M = 33.31, SD = 4.39). The intervention is described so that teachers and consulting school psychologists can implement the steps for individuals or groups (e.g., in a multitiered response to intervention model). © 2009 Wiley Periodicals, Inc. 相似文献

The study compared the agreement, internal consistency, and measurement stability of the GE iDXA, BOD POD, and InBody 720. Body composition of 43 men and 37 women (31.4 ± 10.7 years; 90% Caucasian and 10% other) was assessed in triplicate using each method over two different days. Mean percent body fat (% BF) of the participants was different for all three machines (27.6 ± 10.0% [GE iDXA)] 25.6 ± 10.4% [BOD POD], and 21.3 ± 10.6% [InBody 720]; p < .05). The coefficient of variation for same day repeated measures was 1.06% (GE iDXA), 3.29% (BOD POD), and 2.97% (InBody 720). The coefficient of variation for 2-day repeated measures was 1.81% (GE iDXA), 4.61% (BOD POD), and 4.24% (InBody 720). The difference between the GE iDXA and BOD POD was within acceptable variability, while the InBody 720 significantly underestimated % BF. The internal consistency was highest for the GE iDXA, followed by the InBody 720, and then the BOD POD. 相似文献

In classrooms, race-based bias, discrimination, and inequities result in unsafe and unproductive learning environments. Teacher educators are charged with helping preservice teachers develop racial literacy skills. This self-study explores the ways in which two White teacher educators recognize and attempt to manage challenges during field instruction of White teacher candidates. The teacher educator researchers explore their own Whiteness and use a racial lens to critique their practices. Post-lesson-debriefing conferences between teacher educators and their candidates are shared as illustrative vignettes to reveal instructors’ teaching challenges and failures. Implications for working with White teacher candidates, improvements to field instruction practices, student teaching curricula revisions, and programmatic changes are posited. 相似文献

AbstractThe aim of this study was to determine the physical demands of women’s rugby union match play using time–motion analysis and heart rate (HR) response. Thirty-eight premier club level female rugby players, ages 18–34 years were videotaped and HRs monitored for a full match. Performances were coded into 12 different movement categories: 5 speeds of locomotion (standing, walking, jogging, striding, sprinting), 4 forms of intensive non-running exertion (ruck/maul/tackle, pack down, scrum, lift) and 3 discrete activities (kick, jump, open field tackle). The main results revealed that backs spend significantly more time sprinting and walking whereas forwards spend more time in intensive non-running exertion and jogging. Forwards also had a significantly higher total work frequency compared to the backs, but a higher total rest frequency compared to the backs. In terms of HR responses, forwards displayed higher mean HRs throughout the match and more time above 80% of their maximum HR than backs. In summary, women’s rugby union is characterised by intermittent bursts of high-intensity activity, where forwards and backs have similar anaerobic energy demands, but different specific match demands. 相似文献

The article contains a report of the formation and development of a Centre for Educational Methods established at the University of Manchester Institute of Science and Technology (UMIST). The Centre is a group of the academic staff of the Institute interested in education. It was originally formed to evaluate both old and new teaching methods for use in the Institute. It has developed into a group concerned also with the improvement of education and now organises discussion meetings, courses for lecturers, and an audio‐visual workshop. As an example of the Centre's audio‐visual work, the article stresses the use of television. A personal assessment of the effects of the Centre is included with the suggestion that other educational establishments should consider the formation of such a unit, if they do not already have one. 相似文献

This study investigates how individual differences in 7- to 9-year-olds' curiosity relate to the inquiry-learning process and outcomes in environments differing in structure. The focus on curiosity as individual differences variable was motivated by the importance of curiosity in science education, and uncertainty being central to both the definition of curiosity and the inquiry-learning environment. Curiosity was assessed with the Underwater Exploration game (Jirout, J., & Klahr, D. (2012). Children's scientific curiosity: In search of an operational definition of an elusive concept. Developmental Review, 32, 125–160. doi:10.1016/j.dr.2012.04.002), and inquiry-based learning with the newly developed Scientific Discovery task, which focuses on the principle of designing informative experiments. Structure of the inquiry-learning environment was manipulated by explaining this principle or not. As intelligence relates to learning and possibly curiosity, it was taken into account. Results showed that children's curiosity was positively related to their knowledge acquisition, but not to their quality of exploration. For low intelligent children, environment structure positively affected their quality of exploration, but not their knowledge acquisition. There was no interaction between curiosity and environment structure. These results support the existence of two distinct inquiry-based learning processes – the designing of experiments, on the one hand, and the reflection on performed experiments, on the other – and link children's curiosity to the latter process. 相似文献
