Abstract Six games players (GP) and six endurance‐trained runners (ET) completed a standardized multiple sprint test on a non‐motorized treadmill consisting often 6‐s all‐out sprints with 30‐s recovery periods. Running speed, power output and oxygen uptake were determined during the test and blood samples were taken for the determination of blood lactate and pH. Games players tended to produce a higher peak power output (GP vs ET: 839 ± 114 vs 777 ± 89 W, N.S.) and higher peak speed (GP vs ET: 7.03 ± 0.3 vs 6.71 ± 0.3 m s‐1, N.S.), but had a greater decrement in mean power output than endurance‐trained runners (GP vs ET: 29.3 ± 8.1% vs 14.2 ± 11.1%, P < 0.05). Blood lactate after the test was higher for the games players (GP vs ET: 15.2 ± 1.9 vs 12.4 ± 1.7 mM, P < 0.05), but the decrease in pH was similar for both groups (GP vs ET: 0.31 ± 0.08 vs 0.28 ± 0.08, N.S.). Strong correlations were found between peak blood lactate and peak speed (r = 0.90, P < 0.01) and between peak blood lactate and peak power fatigue (r = 0.92, P<0.01). The average increase in oxygen uptake above pre‐exercise levels during the sprint test was greater for endurance‐trained athletes than for the games players (ET vs GP: 35.0 ± 2.2 vs 29.6 ± 3.0 ml kg‐1 min‐1 , P < 0.05), corresponding to an average oxygen uptake per sprint (6‐s sprint and 24 s of subsequent recovery) of 67.5 ± 2.9% and 63.0 ± 4.5% VO 2 max respectively (N.S.). A modest relationship existed between the average increase in oxygen uptake above pre‐exercise values during the sprint test and mean speed fatigue (r = ‐0.68, P < 0.05). Thus, the greater decrement in performance for the games players may be related to higher glycolytic rates as reflected by higher lactate concentrations and to their lower oxygen uptake during the course of the 10 sprints. 相似文献

This paper addresses the question: is self-assessment in religious education unique? It first presents an overview of some challenges for assessment from subject differences, and then reviews the generic literature on self-assessment. It builds on earlier empirical research on self-assessment in religious education, carried out in an English state secondary school; this was used to propose a variant of self-assessment which is tailored to the demands of religious education – reflexive self-assessment. Its implications for more general understandings of the relationship between subject pedagogy and self-assessment are discussed, especially the recognition of values not only in religious education but in other subjects too, reinforcing the need to develop subject-specific variants of self-assessment that reflect the breadth of learning outcomes. 相似文献

This article illustrates using carbon emissions data in an introductory statistics assignment. The carbon emissions data has desirable characteristics including: choice of measure; skewness; and outliers. These complexities allow research and public policy debate to be introduced. 相似文献

This article addresses a unique effort to implement a summer residential program that identifies and inspires potential educators by reaching down the pipeline to academically talented high school students. The primary goal of the program was to introduce participants to various dimensions of urban teaching. The research and evaluation for the program was designed to include diverse forms of data (quantitative and qualitative) from both staff and program participants. This study??s findings indicate that participants became more informed about prevalent issues in under-resourced urban schools, better understood the need for teachers?? ongoing professional development and felt more comfortable in urban schools. A number of the focal participants also expressed sustained or increased aspirations for teaching youth in urban schools. 相似文献

Web-Teaching deals with all aspects of teaching, using the World Wide Web. Of all of these, the one most likely to have significant impact upon learning is automatic testing. Repeatable testing (formative assessment) has solid research support. Schemes that make extensive use of repeatable testing are not favored by instructors, however, because of the time required for test development, grading, and recording. Web-based automatic testing can automate most or all of the test grading and recording activities. Further, it makes student access easier. The paper addresses dimensions of the issue of automatic, Web-based testing. 相似文献

The implementation of an integrated medical neuroscience course by technologically pivoting an in-person neuroscience course to online using an adaptive blended method may provide a unique approach for teaching a medical neuroscience course during the Covid-19 pandemic. An adaptive blended learning method was developed in response to the requirements necessitated by the Covid-19 pandemic. This model combined pedagogical needs with digital technology using online learning activities to implement student learning in a medical neuroscience course for year one medical students. This approach provided medical students with an individually customized learning opportunity in medical neuroscience. The students had the complete choice to engage the learning system synchronously or asynchronously and learn neuroscience materials at different locations and times in response to the demands required to deal with the pandemic. Students' performance in summative and formative examinations of the adaptive blended learning activities were compared with the previous performance obtained the previous year when the contents of the medical neuroscience course were implemented using the conventional “face-to-face” learning approach. While the cohort of our students in 2019 and 2020 changed, the contents, sessions, volume of material, and assessment were constant. This enabled us to compare the results of the 2019 and 2020 classes. Overall, students' performance was not significantly different between the adaptive blended learning and the in-person approach. More students scored between 70% and 79% during the adaptive blended learning compared with in-class teaching, while more students scored between 80% and 89% during the in-person learning than during the adaptive blended learning. Finally, the percentage of students that scored >90% was not significantly different for both Years 2019 and 2020. The adaptive blended learning approach was effective in enhancing academic performance for high-performing medical students. It also permitted the early identification of underachieving students, thereby serving as an early warning sign to permit timely intervention. 相似文献

Feedback techniques, including computer-assisted feedback, have had mixed results in improving student learning outcomes.
This project addresses the effect of type of feedback, simple or elaborate, for both short-term comprehension and long-term
outcomes. A sample of 75 graduate nursing students was given a total of ten examinations. Four examinations provided tutorials
in which the students received one of two types of feedback, simple or elaborate. Five examinations provided tutorials with
no feedback. A comprehensive final examination compared initial content and final scores. This study found no significant
differences between the types of feedback the students received. The mean scores were significantly higher on the four examinations
where the students received feedback than on the five examinations with no feedback on tutorials. The comparison between the
individual examinations and the similar content portion of the final examination indicated a significant drop in each of the
four examinations where feedback was given and a significant improvement in four of the five examinations where no feedback
was given. 相似文献

The aim of this work was to gather different perspectives on the “key ingredients” involved in creative writing by children – from experts of diverse disciplines, including teachers, linguists, psychologists, writers and art educators. Ultimately, we sought in the experts’ convergence or divergence insights on the relative importance of the relevant factors that may aid writing instruction, particularly for young children. We present a study using an expert knowledge elicitation method in which representatives from five domains of expertise pertaining to writing rated 28 factors (i.e., individual skills and attributes) covering six areas (general knowledge and cognition, creative cognition, conation, executive functioning, linguistic and psychomotor skills), according to their importance for creative writing. A Many-Facets Rasch Measurement (MFRM) model permitted us to quantify the relative importance of these writing factors across domain-specific expertise, while controlling for expert severity and other systematic evaluation biases. The identified similarities and domain-specific differences in the expert views offer a new basis for understanding the conceptual gaps between the scientific literature on creative writing, the writer's self-reflection on the act of writing creatively, and educators’ practices in teaching creative writing. Bridging such diverse approaches–that are, yet, relatively homogeneous within areas of expertise – appears to be useful in view of formulating process-oriented writing pedagogy that may, above all, better target the skills needed to improve children's creative writing development. 相似文献
