In this paper, we propose a theoretical framework for designing on-line situated assessment tools for multimedia instructional systems. Based on an ecological psychology approach to situated learning, a graph theoretic methodology is applied to monitor students' performance (solution paths) throughout the learning activity. Deviation of the student's path from the target (expert) path generates indicators which can function as alerts to the student and to the instructor. The information collected in the dribble files and presented visually enables the instructor to identify problems quickly and intervene appropriately. The feasibility of the methodology is explored in case studies describing three instructional systems that teach (1) critical thinking and problem-solving skills, (2) principles of hemodynamic monitoring and treatment, and (3) orthodontic treatment, respectively. 相似文献

To assist counselors who are supervising students working with clients infected with HIV, this article uses Loganbill, Hardy, and Delworth's (1982) framework to highlight important issues that counselors-in-training are likely to face. 相似文献

The individual members of 35 UK learned societies were surveyed on their attitudes to open access (OA); 1,368 responses were received. Most respondents said they knew what OA was, and supported the idea of OA journals. However, although 60% said that they read OA journals and 25% that they published in them, in both cases around one‐third of the journals named were not OA. While many were in favour of increased access through OA journals, concerns were expressed about the cost to authors, possible reduction in quality, and negative impact on existing journals, publishers, and societies. By contrast, less than half knew what self‐archiving was; 36% thought it was a good idea and 50% were unsure. Just under half said they used repositories of self‐archived articles, but 13% of references were not in fact to self‐archiving repositories. 29% said they self‐archived their own articles, but 10% of references were not to publicly accessible sites of any kind. The access and convenience of self‐archiving repositories were seen as positive, but there were concerns about quality control, workload for authors and institutions, chaotic proliferation of versions, and potential damage to existing journals, publishers, and societies. 相似文献

Nine male student games players consumed either flavoured water (0.1 g carbohydrate, Na+ 6 mmol · l?1), a solution containing 6.5% carbohydrate-electrolytes (6.5 g carbohydrate, Na+ 21 mmol · l?1) or a taste placebo (Na+ 2 mmol · l?1) during an intermittent shuttle test performed on three separate occasions at an ambient temperature of 30°C (dry bulb). The test involved five 15-min sets of repeated cycles of walking and variable speed running, each separated by a 4-min rest (part A of the test), followed by 60 s run/60 s rest until exhaustion (part B of the test). The participants drank 6.5 ml · kg?1 of fluid as a bolus just before exercise and thereafter 4.5 ml · kg?1 during every exercise set and rest period (19 min). There was a trial order effect. The total distance completed by the participants was greater in trial 3 (8441 ± 873 m) than in trial 1 (6839 ± 512, P < 0.05). This represented a 19% improvement in exercise capacity. However, the trials were performed in a random counterbalanced order and the participants completed 8634 ± 653 m, 7786 ± 741 m and 7099 ± 647 m in the flavoured water (FW), placebo (P) and carbohydrate-electrolyte (CE) trials, respectively (P = 0.08). Sprint performance was not different between the trials but was impaired over time (FW vs P vs CE: set 1, 2.41 ± 0.02 vs 2.39 ± 0.03 vs 2.39 ± 0.03 s; end set, 2.46 ± 0.03 vs 2.47 ± 0.03 vs 2.47 ± 0.02 s; main effect time, P < 0.01). The rate of rise in rectal temperature was greater in the carbohydrate-electrolyte trial (rise in rectal temperature/duration of trial, °C · h?1; FW vs CE, P < 0.05; P vs CE, N.S.). Blood glucose concentrations were higher in the carbohydrate-electrolyte than in the other two trials (FW vs P vs CE: rest, 4.4 ± 0.1 vs 4.3 ± 0.1 vs 4.2 ± 0.1 mmol · l?1; end of exercise, 5.4 ± 0.3 vs 6.4 ± 0.6 vs 7.2 ± 0.5 mmol · l?1; main effect trial, P < 0.05; main effect time, P < 0.01). Plasma free fatty acid concentrations at the end of exercise were lower in the carbohydrate-electrolyte trial than in the other two trials (FW vs P vs CE: 0.57 ± 0.08 vs 0.53 ± 0.11 vs 0.29 ± 0.04 mmol · l?1; interaction, P < 0.01). The correlation between the rate of rise in rectal temperature (°C · h?1) and the distance completed was ?0.91, ?0.92 and ?0.96 in the flavoured water, placebo and carbohydrate-electrolyte conditions, respectively (P < 0.01). Heart rate, blood pressure, plasma ammonia, blood lactate, plasma volume and rate of perceived exertion were not different between the three fluid trials. Although drinking the carbohydrate-electrolyte solution induced greater metabolic changes than the flavoured water and placebo solutions, it is unlikely that in these unacclimated males carbohydrate availability was a limiting factor in the performance of intermittent running in hot environmental conditions. 相似文献
