Hypertext is a nonlinear way of presenting content consisting of nodes and links that a person can access using a variety of search and browsing strategies. In this article, we focus on the use of hypertext as an instructional tool. We compare hypertext instruction with traditional instructional formats. We offer some initial guidelines relating to guidance and control, development and implementation, multiuser management, user interface, and content representation. The paper concludes with a discussion of limitations of learner control as an instructional strategy, and the need for careful instructional design of hypertext instructional programs. 相似文献

This article explores changing understandings of Catholic hell in post-war England, focusing on how questions of sex and gender intersected with beliefs in the afterlife. It uses oral testimony from Catholic laypeople alongside the pronouncements of the clerical hierarchy to challenge the pervasive notion that ‘hell disappeared in the 1960s’. Hell did however, change in constitution during the post-war decades, transforming from a material ‘place’ to an abstract ‘state’ in the lay and institutional imagination. Rather than being about a straightforward ‘liberation’ from a coercive theology of damnation, the changing constitution of hell spoke of the way certain religious beliefs became re-categorised in late-modern England. 相似文献

Research indicates that instructing athlete’s to focus on bodily movements (internal focus of attention [IFA]) may hinder performance, whereas instructing them to focus on the movement outcome (external focus of attention [EFA]) often enhances performance. Despite the importance of instructions in striking combat sports, limited research has examined the influence of IFA and EFA on performance in well-trained combat athletes. This study investigated the effects of different instructional cues on punching velocity (m · s?1) and normalised impact forces (N · kg?1) among intermediate (n = 8) and expert (n = 7) competitive boxers and kickboxers. Athletes completed three rounds of 12 maximal effort punches delivered to a punching integrator on three separate days. Day one was a familiarisation session with only control instructions provided. In the following two days athletes randomly received IFA, EFA or control instructions prior to each of the three rounds. Athletes punching with EFA were 4% faster and 5% more forceful than IFA (P < 0.05), and 2% faster and 3% more forceful than control (P < 0.05). Furthermore, experts punched 11% faster and with 13% greater force compared with intermediate athletes (P < 0.05). EFA led to a positive effect on punching performance and should be favoured over IFA and control instructions. 相似文献

This study investigated the effects of a mentally fatiguing test on physical tasks among elite cricketers. In a cross-over design, 10 elite male cricket players from a professional club performed a cricket run-two test, a Batak Lite reaction time test and a Yo-Yo-Intermittent Recovery Level 1 (Yo-Yo-IR1) test, providing a rating of perceived exertion (RPE) after completing a 30-min Stroop test (mental fatigue condition) or 30-min control condition. Perceived fatigue was assessed before and after the two conditions and motivation was measured before testing. There were post-treatment differences in the perception of mental fatigue (P < 0.001; d = ?7.82, 95% CIs = ?9.05–6.66; most likely). Cricket run-two (P = 0.002; d = ?0.51, 95% CIs = ?0.72–0.30; very likely), Yo-Yo-IR1 distance (P = 0.023; d = 0.39, 95% CIs = 0.14–0.64; likely) and RPE (P = 0.001; d = ?1.82, 95% CIs = ?2.49–1.14; most likely) were negatively affected by mental fatigue. The Batak Lite test was not affected (P = 0.137), yet a moderate (d = 0.41, 95% CIs = ?0.05–0.87) change was likely. Mental fatigue, induced by an app-based Stroop test, negatively affected cricket-relevant performance. 相似文献
