The following paper outlines and evaluates the implementation of the use of peer assessment in higher education (HE), using the BA in music course at Kingston University as a case study. The rationale of the peer assessment systems introduced into two curriculum areas is examined, and the operation of the scheme is evaluated, by the use of lecturer interviews, attitudinal questionnaires completed by the participating students, and the assessments and feedback produced. Conclusions drawn are that the introduction of peer assessment seems to improve students’ critical faculties and gives them a greater ownership of the whole assessment process.  相似文献

Instructional animation versus static pictures: A meta-analysis   总被引:8,自引:0,他引:8  
A meta-analysis of 26 primary studies, yielding 76 pair-wise comparisons of dynamic and static visualizations, reveals a medium-sized overall advantage of instructional animations over static pictures. The mean weighted effect size on learning outcome is d = 0.37 (95% CI 0.25–0.49). Moderator analyses indicate even more substantial effect sizes when the animation is representational rather than decorational (d = 0.40, 95% CI 0.26–0.53), when the animation is highly realistic, e.g., video-based (d = 0.76, 95% CI 0.39–1.13), and/or when procedural-motor knowledge is to be acquired (d = 1.06, 95% CI 0.72–1.40). The results are in line with contemporary theories of cognitive load and multimedia learning, and they have practical implications for instructional design.  相似文献

Engaging students as partners (SaP) in teaching and learning is an emerging yet contested topic in higher education. This study interviewed 16 students and staff working in partnership across 11 Australian universities to understand how they conceptualised SaP and the opportunities they believed SaP afforded their universities. Thematic analysis revealed three overlapping conceptions of partnership: SaP as counter-narrative, SaP as values-based practice, and SaP as cultural change. The findings are first interpreted through the lens of liminality and an ethic of care. This is followed by a discussion of inclusivity of involvement, resistance, and reinforcement of neoliberal agendas despite good intentions. Finally, implications for cautious enactment of both practice and research are offered.  相似文献

This paper evaluates the typically applied rules for awarding R&D subsidies. We identify two sources of inefficiency: the selection based on a ranking of individual projects, rather than complete allocations, and the failure to induce competition among applicants in order to extract and use information about the necessary funding. In order to correct these inefficiencies we propose mechanisms that include some form of an auction in which applicants bid for subsidies. Our proposals are tested in a simulation and in controlled lab experiments. The results suggest that adopting our proposals may considerably improve the allocation.  相似文献

We present an innovative course-based undergraduate research experience curriculum focused on the characterization of single point mutations in p53, a tumor suppressor gene that is mutated in more than 50% of human cancers. This course is required of all introductory biology students, so all biology majors engage in a research project as part of their training. Using a set of open-ended written prompts, we found that the course shifts student conceptions of what it means to think like a scientist from novice to more expert-like. Students at the end of the course identified experimental repetition, data analysis, and collaboration as important elements of thinking like a scientist. Course exams revealed that students showed gains in their ability to analyze and interpret data. These data indicate that this course-embedded research experience has a positive impact on the development of students’ conceptions and practice of scientific thinking.  相似文献

This inquiry is an investigation of item response theory (IRT) proficiency estimators’ accuracy under multistage testing (MST). We chose a two‐stage MST design that includes four modules (one at Stage 1, three at Stage 2) and three difficulty paths (low, middle, high). We assembled various two‐stage MST panels (i.e., forms) by manipulating two assembly conditions in each module, such as difficulty level and module length. For each panel, we investigated the accuracy of examinees’ proficiency levels derived from seven IRT proficiency estimators. The choice of Bayesian (prior) versus non‐Bayesian (no prior) estimators was of more practical significance than the choice of number‐correct versus item‐pattern scoring estimators. The Bayesian estimators were slightly more efficient than the non‐Bayesian estimators, resulting in smaller overall error. Possible score changes caused by the use of different proficiency estimators would be nonnegligible, particularly for low‐ and high‐performing examinees.  相似文献

In the pursuit of mass higher education, fears are often expressed that the quality of higher education suffers as access is increased. This quantitative study considers three proxies of educational quality: (1) prior academic achievement of the student, (2) attrition and retention rates and (3) progression rates, to establish whether educational quality suffers when supply is significantly increased. The period of analysis (2009–2011) saw just such an increase in higher education places in Australia, as universities prepared for the removal of all caps on undergraduate domestic student places in 2012. Our analysis reveals that, whilst widening access results in more students with lower levels of academic achievement entering higher education, this does not necessarily equate to a lowering of educational quality. Furthermore, although on average student progression rates dropped slightly, retention rates actually increased in the majority of universities, suggesting high levels of student perseverance. In addition, there were already wide variations in attrition and progression rates between universities, and the changes observed between 2009 and 2011 did not lead to substantial alterations.  相似文献

The relationship between external training load and session rating of perceived exertion (s-RPE) training load and the impact that playing experience, playing position and 2-km time-trial performance had on s-RPE training load were explored. From 39 Australian Football players, 6.9 ± 4.6 training sessions were analysed, resulting in 270 samples. Microtechnology devices provided external training load (distance, average speed, high-speed running distance, player load (PL) and player loadslow (PLslow)). The external training load measures had moderate to very large associations (r, 95% CI) with s-RPE training load, average speed (0.45, 0.35–0.54), high-speed running distance (0.51, 0.42–0.59), PLslow (0.80, 0.75–0.84), PL (0.86, 0.83–0.89) and distance (0.88, 0.85–0.90). Differences were described using effect sizes (d ±95% CL). When controlling for external training load, the 4- to 5-year players had higher s-RPE training load than the 0- to 1- (0.44 ± 0.33) and 2- to 3-year players (0.51 ± 0.30), ruckmen had moderately higher s-RPE training load than midfielders (0.82 ± 0.58), and there was a 0.2% increase in s-RPE training load per 1 s increase in time-trial (95% CI: 0.07–0.34). Experience, position and time-trial performance impacted the relationship between external training load and s-RPE training load. This suggests that a given external training load may result in different internal responses between athletes, potentially leaving individuals at risk of overtraining or failing to elicit positive adaptation. It is therefore vital that coaches and trainers give consideration to these mediators of s-RPE training load.  相似文献

During the 1960s, adidas was the world's leading sports footwear manufacturer. Based in Bavaria and with a history stretching to the 1920s, the company dominated elite sports through aggressive promotion and innovative shoes that catered to athletes' needs. The ‘Superstar’ is one of the company's most successful models, still in production over 40 years since its launch in the late 1960s. Designed to wrest control of the basketball market from American rubber companies, in the two decades that followed it developed cultural meanings far beyond those envisaged by adidas, becoming associated with hip hop, a youth music and subculture born in 1970s New York. Arguing that design is shaped by use and consumption is allied to practice, this article examines the processes by which the ‘Superstar’ came into being, placing it into a wider context of changes within basketball, corporate ambition, and international trade. Tracing the actions and influence of young consumers in New York, it also considers how new ways of thinking about the shoe arose, spread, and were eventually commodified by adidas. It argues that a product's meaning can never be fixed, that producers and consumers are engaged in a constant dialogue over how things are used and perceived.  相似文献

This article reports on the findings of a two year research project on the management of new teacher induction in five LEAs (Turner, 1992). Headteachers, mentors and newly qualified teachers in twelve schools were interviewed as were LEA officers, Inspectors and advisory teachers. The analysis showed the key roles of headteacher, mentor and advisory teacher to be different but complementary. The conclusions are drawn from a detailed analysis of some 180 interviews.  相似文献
