Cognitive Aging and Computer-Based Instructional Design: Where Do We Go From Here?

In this article, themost relevant literature on cognitive aging and instructional design is merged to formulate recommendations for designing computer-based training material aimed at elderly learners. The core message is that researchers and instructional designers do not need to develop special computerized instruction for older adults. Rather, existing principles of general instructional and multimedia design can be evaluated and used to accommodate the needs of elderly learners. Particular attention is given to John Sweller’s Cognitive Load Theory (CLT) and Richard Mayer’s Cognitive Theory of Multimedia Learning (CTML). It is argued that these instructional theories bear important benefits for older learners because they support an efficient use of available cognitive resources. New research directions are suggested to test the implications of these theories for learning in old age.

Premature closure and guided reinvention: a case study in a web‐based learning environment

Just as linguistic errors have provided insights into the nature of linguistic competence(s), detailed analyses of blind spots or marked trajectories in the reflection cycles of novice teachers may provide a window on their underlying beliefs, and thus on relevant zones of proximal development. In this paper we analyse a case study in an experimental web‐based learning environment in which a novice teacher demonstrably just reproduces the assumptions she started out with rather than re‐inspecting them. Having located a problem of motivation uniquely inside the learners’ heads, she pointedly ignores hints in the feedback that her own verbal and nonverbal behaviour in the classroom might be a relevant domain of enquiry. Our findings show the need for structural interventions within a priori hypothesized, linearly ordered, stages in reflection models. We report on two small‐scale experiments that implement suggested changes in the architecture of the web site which yield more context‐sensitive ways of scaffolding reflection. In conclusion we argue that detailed discursive accounts of successful and less successful reflection trajectories are needed to refine and further develop models in teacher thinking.     

自适应学习系统中双向适应交互评价实证研究

随着信息技术的快速发展,网络学习已经成为人们生活中不可或缺的一种学习方式。以实现网络个性化学习为目标的自适应学习系统成为提高网络学习质量的重要研究课题。然而目前大多数自适应学习系统仅具有单向适应能力,即实现了系统根据用户特性适应性向学习者呈现学习资源、过程和策略的功能。尽管这种功能有助于解决学习者认知超载和网络迷航问题,一定程度上提高了学习效率,但学习者在此系统中是一种被动学习,不利于培养学习者自主学习能力和创新能力,也不利于促进学习者对知识的主动建构,还容易使学习者产生惰性。因此,应该充分考虑学习者和系统之间的主客体关系,在自适应学习系统中建立双向适应交互,即用户主动选择资源的适应性交互和系统主动推送资源的自适应交互。双向适应交互最为关键的是用户模型,而认知风格是用户模型中影响学习者个体差异的一个重要元素。从学习效率和使用感受两个层面实证评价双向适应交互性,以及认知风格对其的影响发现:采用自适应学习方式,学习者具有更积极的学习态度,能够取得更好的学习绩效;但认知风格会影响到自适应学习和适应性学习的绩效。     

加工中心的刀具选择和使用

Examining public acquisition of science knowledge from social media in Singapore: an extension of the cognitive mediation model

This study extends the cognitive mediation model (CMM) by examining the role of social media in cultivating public science knowledge. A sample of 901 Singaporeans was collected through an online survey panel. The results showed that the CMM could be applied to a social media context with a focus on science literacy. Specifically, the findings indicated that people with higher levels of surveillance gratification and social utility motivations tended to pay more attention and to elaborate more about science news that they encounter on social media. Likewise, people with greater social utility motivation tended to engage in greater interpersonal discussions on social media. Notably, attention to news on social media had an indirect association with science knowledge through news elaboration and interpersonal discussion on social media. Implications for theory and practice for science communication were discussed.     

Cognitive distortions and autonomy among Chinese university students

The purpose of this study was to examine the roles of university students' cognitive distortions in their sense of autonomy. One hundred and three third-year university students from Shanghai, The People's Republic of China, responded to the Cognitive Distortion Scales [Briere, J. (2000). Cognitive Distortion Scales: Professional manual. Lutz, FL: Psychological Assessment Resources, Inc.] and to the Iowa Developing Autonomy Inventory [Jackson, L. M., Hood, A. B. (1985). The Iowa Developing Autonomy Inventory. In A. B. Hood (Ed., 1997), The Iowa student development inventories (2nd Ed), (pp. 32–43). Iowa City, IA: HITECH Press]. Results suggested that in general, cognitive distortions have a significantly negative impact on Chinese students' sense of autonomy. However, there was also an indication that cognitive distortions could play the roles of psychological defense mechanisms, which provided some support to Bowins' [Bowins, B. (2004). Psychological defense mechanisms: A new perspective. American Journal of Psychoanalysis, 64 (1), 1–26] recent argument that cognitive distortions may not always be dysfunctional. Implications of the present findings are discussed in relation to students, faculty members, and university counselors.     

新农村建设的社会资本路径探析

社会资本意指普通公民的民间参与网络,以及体现在这种约定中的公共精神、社会舆论和互惠规范,它通常被理解成结构型和认知型源泉之间的某种组合。结构型社会资本和认知型社会资本通过不同的作用机制推动新农村建设的进程。乡村社会资本因其公共物品性面临供给和投资不足的困境,乡镇政府应当承担起投资乡村社会资本的责任。     

英语词缀的语法化研究

语法化研究语法形式来源和固化的问题,是语言学家长期关心的问题。认知语言学对语法化研究非常重视。词缀作为词汇扩展演化的重要工具,反映了人类语言词汇的重要特征,从语言认知加工的角度来看．词缀有利于语言的使用者以较小的认知能量获取较大的认知效益。
