Although student self-assessment is considered a critical component of assessment for learning, its use and related research
are rare in higher education. This article describes an action research study of self-assessment as an instructional strategy
in two university courses. Results indicate that self-assessment exercises provided students the opportunity to reflect on
the course and their performance, helped them monitor their own progress, motivated them to do well in the course, and provided
them the opportunity to give feedback to the instructor. Additionally, from the instructor perspective, the exercises provided
useful feedback for course improvement and facilitated interactions and relationships with students. 相似文献

Application of physiological methods, in particular electroencephalography (EEG), offers new and promising approaches to educational
psychology research. EEG is identified as a physiological index that can serve as an online, continuous measure of cognitive
load detecting subtle fluctuations in instantaneous load, which can help explain effects of instructional interventions when
measures of overall cognitive load fail to reflect such differences in cognitive processing. This paper presents a review
of seminal literature on the use of continuous EEG to measure cognitive load and describes two case studies on learning from
hypertext and multimedia that employed EEG methodology to collect and analyze cognitive load data. 相似文献

Due to the complexity of the legal domain, reasoning about law cases is a very complex skill. For novices in law school, legal
reasoning is even more complex because they have not yet acquired the conceptual knowledge needed for distilling the relevant
information from cases, determining applicable rules, and searching for rules and exceptions in external information sources
such as lawbooks. This study investigated the role of conceptual knowledge in solving legal cases when no information sources
can be used. Under such ‘unsupported’ circumstances, novice and advanced students performed less well than domain experts,
but even experts’ performance was rather low. The second question addressed was whether novices even benefit from the availability
of information sources (i.e., lawbook), because conceptual knowledge is prerequisite for effective use of such sources. Indeed
availability of the lawbook positively affected performance only for advanced students but not for novice students. Implications
for learning and instruction in the domain of law are discussed. 相似文献

ABSTRACTDifferences and similarities between table tennis and other racquet sports exist, but are not well documented in the literature, in spite of the relevance for talent identification. In this study we aimed at identifying the key characteristics of table tennis in comparison with tennis and badminton based upon a survey in coaches. A total of 177 licensed coaches from all across the world and with diverse professional backgrounds completed a survey on anthropometric measures, physical performance, and motor coordination skills. On a scale from 1 to 10, coaches indicated to what extent a talent characteristic was important for their sport. MANOVA identified key differences as well as similarities between all three racquet sports and a subsequent discriminant analysis allocated coaches correctly for table tennis, tennis, and badminton 81.01%, 55.6%, and 71.4% respectively. Our results show that table tennis and other racquet sport coaches are well aware of differences between the racquet sports and also the importance and value of testing and assortment of skill components. These findings can assist coaches in future talent orientation and transfer in racquet sports. 相似文献

This article offers a case study of the evaluation of a redesigned and redeveloped laboratory-based cell biology course. The course was a compulsory element of the biology program, but the laboratory had become outdated and was inadequately equipped. With the support of a faculty-based teaching improvement project, the teaching team redesigned the course and re-equipped the laboratory, using a more learner-centered, constructivist approach. The focus of the article is on the project-supported evaluation of the redesign rather than the redesign per se. The evaluation involved aspects well beyond standard course assessments, including the gathering of self-reported data from the students concerning both the laboratory component and the technical skills associated with the course. The comparison of pre- and postdata gave valuable information to the teaching team on course design issues and skill acquisition. It is argued that the evaluation process was an effective use of the scarce resources of the teaching improvement project. 相似文献

It is well known that sport and exercise play an important role in stimulating site-specific bone mineral density (BMD). However, what is less well understood is how these benefits dissipate throughout the body. Hence, the aim of the present study was to compare the BMD (recorded at nine sites throughout the skeleton) of 106 male athletes (from nine sports) with that of 15 male non-exercising age-matched controls. Given that BMD is known to increase with body mass and peak with age, multivariate and univariate analyses of covariance were performed to compare the BMD of the nine sports groups with controls (at all sites) using body mass and age as covariates. Our results confirmed a greater adjusted BMD in the arms of the upper-body athletes, the right arm of racket players and the legs of runners (compared with controls), supporting the site-specific nature (i.e. specific to the externally loaded site) of the bone remodelling response (all P?<0.01). However, evidence that bone mass acquisition is not just site-specific comes from the results of the rugby players, strength athletes, triathletes and racket players. The rugby players' adjusted BMD was the greatest of all sports groups and greater than controls at all nine sites (all P?<0.01), with differences ranging from 8% greater in the left arm to 21% in the lumbar spine. Similarly, the strength athletes' adjusted BMD was superior to that of controls at all sites (P?<0.05) except the legs. The adjusted BMD of the triathletes was significantly greater than that of the controls in both the arms and the legs as well as the thoracic and lumbar spine. The racket players not only had significantly greater right arm BMD compared with the controls but also a greater BMD of the lumbar spine, the pelvis and legs. In contrast, the low-strain, low-impact activities of keep-fit, cycling and rowing failed to benefit BMD compared with the age-matched controls. These results suggest that sporting activities involving high impact, physical contact and/or rotational forces or strains are likely to convey significant benefits not only to the loaded sites, but also to other unloaded peripheral and axial sites throughout the skeleton. 相似文献

Abstract The aim of the present study was to determine the repeatability of a running endurance test using an automated treadmill system that requires no manual input to control running speed. On three separate occasions, 7 days apart, 10 experienced male endurance-trained runners (mean age 32 years, s = 10; [Vdot]O2peak 61 ml · kg?1 · min?1, s = 7) completed a treadmill time trial, in which they were instructed to run as far as possible in 60 min. The treadmill was instrumented with an ultrasonic feedback-controlled radar modulator that spontaneously regulated treadmill belt speed corresponding to the changing running speed of each runner. Estimated running intensity was 70%[Vdot]O2peak (s = 11) and the distance covered 13.5 km (s = 2), with no difference in mean performances between trials. The coefficient of variation, estimated using analysis of variance, with participant and trial as main effects, was 1.4%. In summary, the use of an automated treadmill system improved the repeatability of a 60-min treadmill time trial compared with time trials in which speed is controlled manually. The present protocol is a reliable method of assessing endurance performance in endurance-trained runners. 相似文献

Abstract The effect of active and passive recovery on repeated-sprint swimming bouts was studied in eight elite swimmers. Participants performed three trials of two sets of front crawl swims with 5 min rest between sets. Set A consisted of four 30-s bouts of high-intensity tethered swimming separated by 30 s passive rest, whereas Set B consisted of four 50-yard maximal-sprint swimming repetitions at intervals of 2 min. Recovery was active only between sets (AP trial), between sets and repetitions of Set B (AA trial) or passive throughout (PP trial). Performance during and metabolic responses after Set A were similar between trials. Blood lactate concentration after Set B was higher and blood pH was lower in the PP (18.29 ± 1.31 mmol · l?1 and 7.12 ± 0.11 respectively) and AP (17.56 ± 1.22 mmol · l?1 and 7.14 ± 0.11 respectively) trials compared with the AA (14.13 ± 1.56 mmol · l?1 and 7.23 ± 0.10 respectively) trial (P < 0.01). Performance time during Set B was not different between trials (P > 0.05), but the decline in performance during Set B of the AP trial was less marked than in the AA or PP trials (main effect of sprints, P < 0.05). Results suggest that active recovery (60% of the 100-m pace) could be beneficial between training sets, and may compromise swimming performance between repetitions when recovery durations are short (< 2 min). 相似文献
