基于趣味性情境的“三位一体”博物馆教育——对儿童讲解辅导中兴趣与情境的重新认识与提升

面向儿童群体讲解自然科普展览是许多博物馆开展教育活动的重要方式。然而,传统讲解无法激发儿童兴趣,难以进行学习迁移和延伸。本文以云南省博物馆“远古云南”展厅为例,从三因素情境性兴趣模型出发,运用“情境认知与学习理论”和“情境教学法”对兴趣和情境进行深度分析,提出“情境化讲解辅导设计三步法”。通过实践,实现多样化情境和趣味性紧密结合,形成融合趣味性、教学内容、教学方法的“三位一体”博物馆讲解辅导,鼓励儿童把学习变为实践,逐步建立起自我与自然的联系。     

“李吉林情境教育探索”再理解

李吉林的情境教育思想是既有理论依据,又有相应行动方案,且经过亲身实践验证的教育思想;在李吉林的情境教育探索中,学生不仅是教师所创构的情境的享受者,而且是不断形成、丰富、优化的师生共同情境的创构者;情境教育特别需要教师有爱心、童心及恒心;李吉林的情境教育探索不仅含有"中国元素"、具有"中国特色",而且含有"人类元素"、具有"世界意义"。     

How repeated studying and testing affects multimedia learning: Evidence for adaptation to task demands

Two biases can occur in multimedia learning: overconfidence and over-reliance on text processing. The present research sought to identify these biases and to investigate whether they can be reduced, and hence learning fostered, when studying and testing are repeated. In 2 experiments (Exp.1: N = 79, Exp.2: N = 52), students learned either with text only or with text and pictures (multimedia) about how the toilet flush works, gave judgments-of-learning (JOLs), were tested on the learning contents; afterwards this study-test cycle was repeated. Results from both experiments revealed stronger overconfidence due to multimedia in both study-test cycles (JOLs higher than learning outcomes). Eye movement data showed a relative increase in attention on the picture versus text from cycle 1 to cycle 2; this relative increase in attention was related to better learning outcomes. Repeated studying and testing thus helped to reduce over-reliance on text processing in multimedia learning, fostering performance.

不同母语背景留学生汉语阅读中字音、字形作用的特点

采用校正任务探讨了母语为拼音文字和表意文字的外国留学生在汉语阅读中字音、字形作用的特点。结果表明，初级汉语水平的拼音文字背景留学生字音发挥主要作用，中级汉语水平的拼音文字背景留学生字音、字形起相同重要作用；无论是初级汉语水平还是中级汉语水平的表意文字背景留学生，都是字形发挥主要作用。本研究结果初步表明，初级汉语水平留学生主要受其母语认知加工特点的影响，中级汉语水平留学生受到母语和目的语认知加工特点两个方面的影响。

Do karate fighters use situational probability information to improve decision-making performance during on-mat tasks?

This study examined the contribution of situational probability information to the perceptual and cognitive processes underlying decision-making behaviour during in situ Karate performance. Experts and novices were required to make decisions about various attacks in different fight scenarios. The order in which the fight situations were presented was modified in order to provide advanced probability information and identify whether fighters were able to use the latter information to make better decisions. Specifically, one of the attacks was repeated every four actions. Results revealed that experts were more accurate and faster than their less skilled counterparts to block and counterattack the opponent. The experts picked up the occurrence of the attack pattern after the fifth repetition whereas novices did not. This enabled experts to improve decision time and decision accuracy. Findings suggest that such superiority could stem from the perceptual and cognitive skills possessed by the experts, thus giving them the opportunity to recognise a situation more easily. This was reinforced by gaze behaviour which demonstrated that experts used a more efficient search strategy involving fewer fixations of longer duration on a lesser number of areas relative to the novices. Moreover, experts generated more refined karate-specific knowledge structures compared with the novices.     

Timescales for exploratory tactical behaviour in football small-sided games

The aim of this study was to identify the dynamics of tactical behaviour emerging on different timescales in football small-sided games and to quantify short- and long-term exploratory behaviour according to the number of opponents. Two teams of four professional male footballers played small-sided games against two different teams with a variable number of opponents (3, 5 and 7). Data were collected using a combination of systematic observation and a non-differential global positioning system (15 Hz). The temporal diversity and structural flexibility of the players were determined by calculating the dynamic overlap order parameter q, entropy and trapping strength. Analysis of the exploratory dynamics revealed two different timescales, forming a different metastable landscape of action for each constraint. Fast dynamics lasted on average a few seconds and consisted of changes in tactical patterns. The long timescale corresponded to the shared tasks of offence and defence lasting tens of seconds. The players’ tactical diversity decreased with an increasing number of opponents, especially in defence. Manipulating numerical imbalance is likely to promote changes in the diversity, unpredictability and flexibility of tactical solutions. The fact that the temporally nested structure of constraints shaped the emergence of tactical behaviour provides a new rationale for practice task design. The manipulation of numerical imbalance on the timescale of a few tens of seconds, on which the exploratory behaviour of players saturates, may help coaches to optimise the exploratory efficiency of the small-sided games.
