Homemade PowerPoint games are a low-tech alternative for using game design in classrooms. To date, much of the research examining the games has not shown an improvement in performance. This has led some to question whether the games are properly aligned with the instructional strategies researchers have used as justifications to support using them. This study examined how increasing the structure of the game design project affected student performance when compared to control groups, as well as those who created games in previous iterations of the study. In addition, we examined the effects of student performance when two of the instructional strategies (microtheme writing and question writing) were tested in isolation. Most of the comparisons showed no statistical difference in performance; however, results from the final iteration yielded significant gains when compared to the control group.  相似文献

The effect of technology-enhanced learning (TEL) strategies in higher education has arguably been transformative despite the not-insignificant barriers existing in this context. Throughout the discourse very little attention has been paid to those primarily responsible for this implementation—academic teaching staff. This paper aims to highlight the impact of academic workload allocations, an often silent barrier to the uptake of TEL strategies in higher education. We will discuss the effects of academic identity and culture, preferential time allocation to associative activities, academic technological capacity, university policies and workload and funding models on the uptake, and implementation on TEL in higher education. Our aim is to highlight the risks to staff, students and institutions should these concerns not be addressed and to propose a model for utilisation by all staff responsible for implementing flexible workload models supportive of further implementation of TEL strategies across the sector.  相似文献

The reputation disparity between teaching and research has stirred up an unending debate. The age-long notion that teaching and research overlap has become a controversial issue in academia. Consequences of the institutionalization of Publish OR Perish (POP) abound in the literature. This paper investigates the reputations disparity between teaching and research productivity and the rewards for these academic activities. It explores which, out of teaching activities and research publications receive higher or less attention and rewards. Relevant existing literature was reviewed to establish the institutionalization of POP and its consequences of the reputations disparity between teaching and research and its adverse effects on these activities. Evidence from the literature reviewed reveals the existence of POP reputation disparity as part of its consequences. A key finding is that teaching activities are insignificant and unrewarded as research publications. Neither the effectiveness nor the number of teaching loads counts like the numbers of publications.  相似文献

An improvement on the transient response of tracking for the sampled-data system based on an improved PD-type iterative learning control (ILC) is proposed in this paper. The developed analog ILC method and the high-gain property tracker design methodology are first combined to significantly reduce learning epochs and overcome the initial condition shift problem and discontinuous reference input in the traditional ILC. Besides, the proposed ILC improves the transient response and decreases the rate of weighting matrices QQ to RR under the traditional linear quadratic tracker design. First, the off-line observer/Kalman filter identification (OKID) is used to determine the appropriate (low-) order system parameters and state estimator for the physical system with unknown system equation, so that the model-based PD-type ILC can be implemented for practical applications. Then, to improve the transient response and decrease the control effort, the proportional difference type (PD-type) ILC algorithm is combined with the high-gain property linear quadratic tracker (LQT) design to construct the high performance tracker for the model-based sampled-data systems. Furthermore, the discrete-time version high performance tracker design for the unknown stochastic sampled-data system via the iterative learning control method is proposed in this paper based on the Euler method and the digital redesign approach. Finally, some examples are given for illustrating the effectiveness of the proposed method.  相似文献

This discussion focuses on how the rise of America's national sporting pastimes, during the period 1880–1920, was inextricably tied to the ambitions and outpourings of American print capitalism and a concomitant congealing of a sense of modern American nationhood. In examining this thematic, we explicate the manner in which American national sporting audiences during the period 1880–1920 were variously constituted through discourses of national and ethnic sporting difference or Otherness. Hence, we examine the popular representation of turn of the century rodeo practices (as narrated through the spectacle of the western showman William Frederick ‘Buffalo Bill’ Cody's Wild West show productions), the position of early-twentieth-century American baseball in relation to other sporting cultures (graphically depicted by Albert Goodwill, or A.G., Spalding's promotional publications, specifically the 1911 America's National Game) and the national and ethnic differences discerned within the global sporting landscape more generally (explicated within the 1919 National Geographic article ‘The Geography of Games’). These performances and representations of ethnic and national sporting Otherness played an important role in re-inscribing and legitimating the (White European American) normative core of American sport culture (as manifest within and through the dominant practices of playing and/or spectating of football, baseball and basketball).  相似文献

The purpose of this article is to enumerate a series of security steps that might be taken by those researchers or organizations that are contemplating web-based tests and performance assessments. From a security viewpoint, much of what goes on with web-based transactions is similar to other general computer activity, but the recommendations here focus on what can be done to avoid the loss, compromising, or modification of data collected by or stored through the Internet.  相似文献
