Metacognitive learning: the effect of item-specific experience and age on metamemory calibration and planning

Metacognition is a person’s ability to think about their own thinking, to think about their own cognitive ability and knowledge and then to take the appropriate regulatory steps when a problem is detected. Although considerable research has examined the level of such ability in various contexts, there has been relatively little study on whether metacognition can be improved with experience. The present research examined this question for both general (lifetime experience) and item-specific (repetition) experience. Metamemory calibration (correlations between memory predictions and performance) and planning (correlations between memory predictions and study decisions) were examined in both young and older adults. The results indicated that both calibration and planning efficiency increased only with item-specific experience, and even though calibration benefited from experience equally for young and older adults, only younger adults showed better improvement in planning with experience.

A derived grid-based model for simulation of pedestrian flow

We present a derived grid-based model for the simulation of pedestrian flow. Interactions among pedestrians are considered as the result of forces within a certain neighbourhood. Unlike the social force model, the forces here, as in Newtonian physics, are proportional to the inverse of the square of the distance. Despite the notion ofneighbourhood and the underlying grid, this model differs from the existing cellular automaton （CA） models in that the pedestrians are treated as individuals. Bresenham＇s algorithm for line rastering is applied in the step calculation.     

Recognising Prior Learning: Understanding the Relations Among Experience, Learning and Recognition from a Constructivist Perspective

This article discusses the relation between experience and learning in the context of recognition of prior learning (RPL) and from an experiential constructivist perspective. The study is based on a case of in-service training, based on RPL, in the care sector for elderly people. The data consist of interviews with actors in this process, which have been analysed with a qualitative interpretative approach. The results show how prior learning plays a central role in the training process, both on an individual and a collective level. The participants’ prior learning is taken as the starting point, particularly in learning conversations where prior learning is made visible and used, and where participants learn from each other. Further, new learning is taking place as a consequence of the recognition process, and the study particularly highlights how prior experiences could be the basis of new learning in a process of reflection and discussion.     

Inter-professional working and learning: instructional actions and boundary crossing or boundary making in oral healthcare

Inter-professional teams are typical in health care, and inter-professional education has thus become more common. This empirical study explores the instruction-related challenges when students of dentistry and oral hygiene collaborate during their internship in caring for the oral health of patients. The conceptual framework of the study stems from cultural-historical activity theory, the aim being to explore the instructional actions and boundary crossing of clinical instructors while they were supervising the students. The main data comprise 17 videotaped treatment sessions, which were organised three-dimensionally in sequences, themes and topics, and analysed in terms of the instructional and boundary-crossing actions. The results reveal chains of subtle and rich instructional actions classified as instructive, evaluative and collaborative. Instructional boundary crossing occurred rarely and was also boundary-making: positioning, moving and communicating. It should be taken into account in the field of inter-professional working and learning that instructional boundaries seem easier to maintain than to cross, and professional teachers at educational institutions and instructors in workplaces need to be aware of this.     

Monitoring markers of muscle damage during a 3 week periodized drop-jump exercise programme

The aim of this study was to examine changes in indirect markers of muscle damage during 3 weeks of stretch-shortening exercise with a progressively increasing load and continued modulation of various key training variables. Eight healthy untrained men performed a drop-jump programme involving a progressive increase in load impact with respect to the number of jumps performed, drop (platform) height, squat depth amplitude, and addition of weights. Maximal concentric and isometric knee extensor strength were assessed immediately before and 10?min after each training session. Voluntary and 100 Hz-stimulation-evoked torque decreased acutely after each training session relative to pre-exercise values (P?相似文献   

Effect of resistance training regimens on treadmill running and neuromuscular performance in recreational endurance runners

The purpose of this study was to assess the effects of heavy resistance, explosive resistance, and muscle endurance training on neuromuscular, endurance, and high-intensity running performance in recreational endurance runners. Twenty-seven male runners were divided into one of three groups: heavy resistance, explosive resistance or muscle endurance training. After 6 weeks of preparatory training, the groups underwent an 8-week resistance training programme as a supplement to endurance training. Before and after the 8-week training period, maximal strength (one-repetition maximum), electromyographic activity of the leg extensors, countermovement jump height, maximal speed in the maximal anaerobic running test, maximal endurance performance, maximal oxygen uptake ([V·]O(?max)), and running economy were assessed. Maximal strength improved in the heavy (P = 0.034, effect size ES = 0.38) and explosive resistance training groups (P = 0.003, ES = 0.67) with increases in leg muscle activation (heavy: P = 0.032, ES = 0.38; explosive: P = 0.002, ES = 0.77). Only the heavy resistance training group improved maximal running speed in the maximal anaerobic running test (P = 0.012, ES = 0.52) and jump height (P = 0.006, ES = 0.59). Maximal endurance running performance was improved in all groups (heavy: P = 0.005, ES = 0.56; explosive: P = 0.034, ES = 0.39; muscle endurance: P = 0.001, ES = 0.94), with small though not statistically significant improvements in [V·]O(?max) (heavy: ES = 0.08; explosive: ES = 0.29; muscle endurance: ES = 0.65) and running economy (ES in all groups < 0.08). All three modes of strength training used concurrently with endurance training were effective in improving treadmill running endurance performance. However, both heavy and explosive strength training were beneficial in improving neuromuscular characteristics, and heavy resistance training in particular contributed to improvements in high-intensity running characteristics. Thus, endurance runners should include heavy resistance training in their training programmes to enhance endurance performance, such as improving sprinting ability at the end of a race.     

Assessing “The Regulars”—and Beyond

Commenting on online news articles must be considered an online staple—an established practice among news consumers that is currently being funnelled from the Web pages of news organizations to third-party platforms such as Facebook. The paper at hand adopts an exploratory approach and provides insights into the fervency and popularity of commentators and comments on the Facebook pages of two Swedish and two Norwegian newspapers. The results indicate that while immigration issues are a common topic in both countries, the Swedish context stands out by also featuring high degrees of commenting activity in relation to issues of gender equality. Identifying a series of differences in how these opportunities to comment on news are used in each country, the Swedish context appears to offer a wider range of opinions among the most fervent commentators in comparison with Norway. A similar tendency is found among the most “liked” comments.
