A one-group quasi-experimental design and survey methodology were used to investigate the effect of virtual laboratory practices on preservice teachers’ (N = 29) graphic comprehension and interpretation skills with different learning approaches. Pretest and posttest data were collected with the Test of Understanding Kinematic Graphs. The Learning Approaches Scale was administered to the preservice science teachers to determine if they used an in-depth, superficial, or strategic approach. These data were analyzed using non-parametric statistics. The effect of virtual laboratory practices on these preservice teachers’ graphic comprehension and interpretation skills was evaluated, and a significant pretest–posttest gain for “Selecting the graphic related to the explanation of movement” was found. Suggestions are made to address the effects of teaching models and technology-integrated learning environments on students’ learning approach in science courses at different levels of education. 相似文献

We examine the labor market for the highly trained in nanotechnology and the response of universities toward providing training. We draw comparisons with the labor market and university response in bioinformatics. The demand analysis is based on position announcements in Science in 2002 compared to 2005. We also analyze online position announcements in late 2005 and early 2006. Our analysis leads us to conclude that at the present time the market is small and growing for positions in academe and at FFRDCs, small and stable for positions at firms. Our analysis of training leads to the conclusion that the pipeline is being filled primarily through a principal investigator approach, where a student is attached to one faculty member's lab, rather than to a formal program. The fundamental difference between nanotechnology and bioinformatics in this respect may be due to differences in the opportunities available to universities and faculty. 相似文献

AbstractThe introduction of Philosophy and Ethics to the Western Australian Certificate of Education courses in 2008 brought philosophy into the Western Australian secondary school curriculum for the first time. How philosophy came to be included is part of a larger story about the commitment and perseverance of a relatively small number of Australian educators and their belief in the value of introducing philosophical communities of inquiry into school classrooms through a revised pedagogy which could sit comfortably with an outcomes-based education system. 相似文献

The present study examines how learnersinteract with one another within the context ofa computer conference for the purposes ofpassing a test. In a faked computer conferencewith predetermined messages, both the number ofmessages irrelevant to the topic, and theexplicit threading of messages were varied in a2 × 2 design (n = 54). Subjects participated in anasynchronous fashion over a course of fourlog-in sessions. In general, learners indicateda fairly consistent pattern of reception. Theyopened virtually all messages, grouped them ina non-chronological order, and processed themaccording to their topic relevance. Thispattern was also mediated by the conferencecharacteristics. Explicit threading led tosequences of message readings that were morecontent oriented. Similarly, fewer irrelevantmessages lead to prolonged reading times ofrelevant messages. Whereas learning success wasnot affected by conference characteristics,explicitly threaded messages decreased theperceived cognitive demands. 相似文献

In the literature addressing the determinants of TV audiences in sports, both the absolute and relative playing strength of the opponents play a prominent role. Regarding national team competitions, however, this study conjectures that patriotism matters as well. Analyzing the Swiss TV audience at 2 World Cups and 2 European Football Championships, this study finds strong evidence that TV ratings are highly affected by the sizes of the groups of foreign residents affiliated with the teams playing on the field. 相似文献

The aim of the study was to examine the effects of three different training models on aerobic power and body composition in recreationally active runners. According to their preferences 54 subjects (female=?27, male?=?27) were assigned to the following groups: (a) weekend group (WE), who performed two sessions of continuous endurance training weekly, (b) after-work group (FE) who carried out four sessions of high intensity training as well as an additional endurance run and (c) STAR group (STAR), who took part in a training with exercise telemetry monitors based on the heart rate variability. Over the 12-week study period the mean training volume was approximately 2 h 15 min per week. Of the participants 47 successfully completed the training study and all 3 groups showed significantly improved aerobic power (p?<0.001); however, the FE group (d?=?1.15) showed increased VO2max superior to WE (d?=?0.48) and STAR (d?=?0.66) groups. Significant improvements in body mass (p?<?0.001), body fat (p?<?0.001) and visceral fat (p?<?0.001) were found in the WE, FE and STAR group. All groups completed the half marathon with no significant differences in performance. Based on a similar training volume, short, intensive endurance training sessions of about 30 min were found to elicit the greatest improvements of VO2max in recreationally active runners. 相似文献
