自我解释已经为许多研究所证实,但是多数研究使用的都是自然学科的内容作为实验材料,探讨散文学习过程中自我解释的研究较少.因此,本研究引入组别变量,自我解释对散文学习的影响.结果发现:(1)自我解释对散文学习产生了影响,对散文的阅读理解具有促进作用;(2)自我解释对散文学习产生影响机制可能是认知缺口填补和心理模型修正(3)自我解释是可以学习和迁移的,并且其中提供的反馈有助于提升自我解释的准确性. 相似文献

知识教学中认知策略与原有知识间关系的实验研究 总被引:2,自引:0,他引:2
模拟课堂教学情境,探讨知识教学中学习者的认知策略与原有知识间的相互关系。研究表明,二者存在明显的相互作用,策略学习只有在学习者具备适当原有知识的基础上才能有效地促进学习;当原有知识缺乏时,策略教学对学习成绩没有显著性影响;原有知识水平的高低可直接影响学生的学习成绩。该结论对于实际教学工作具有一定的指导意义。 相似文献

在校大中学生自我价值感和自我评价关系的初步研究 总被引:4,自引:0,他引:4
本研究共分两个部分,研究一用Rosenberg自我价值感量表和自我评价量表调查了630名被试,结果表明:(1)自我价值感与具体自我评价的相关广泛存在,不仅限于少数领域;(2)个体对品质的重视程度对自我价值感影响不大;(3)高、低自我价值感者在具体自我评价上的显着差异普遍存在,自我价值感越高对自己在各方面的评价就越高。研究二用自我价值感量表和田纳西自我概念量表调查了193名被试,结果表明,低自我价值感者的自我评价略低于一般受试者,而高自我价值感者的自我评价则比一般受试者高得多。 相似文献

自我解释是指个体如何思考自我及其与他人的关系。在集体主义-个人主义维度下, 东西方人分属于典型的相依性-独立性自我解释:自我参照任务中, 东亚人的自我和重要他人(如母亲)均表征于内侧前额叶皮质(MPFC), 西方人的自我和重要他人分表征于不同脑区; 偶发任务和词-音不一致任务中, 相依性自我解释程度分别调节P3和N400的活动; 文化启动任务中, 双文化被试可通达相应的自我解释。社会脑假设、文化-基因协同进化论和神经-文化交互作用模型对此进行了阐释。未来应研究中国人的关系自我, 尤其是探索本土化的理论和研究方法。 相似文献

调节焦点理论提出,自我调节过程中存在着提升焦点和预防焦点这两种不同的目标追求策略。基于以往研究,本研究提出,自我解释和时间距离会交互影响着人们的调节焦点。研究结果发现,自我解释能够显著地预测调节焦点;独立自我解释更可能激活个体的提升焦点倾向,而依赖自我解释更可能激活个体的预防焦点倾向。此外,近期时间距离启动条件下,独立和依赖自我解释使得个体的调节焦点的差异倾向性更为明显,但是对远期时间距离的知觉则使得依赖自我解释的个体更加偏离预防焦点倾向,趋向于提升性焦点,并与独立自我解释差异不大。 相似文献

采用组间实验设计,以汉语科技说明文为阅读材料,探讨自我解释与工作记忆对汉语阅读理解的影响以及工作记忆对自我解释活动本身的影响.结果表明:(1)自我解释活动促进了被试对文本的理解.(2)较高的言语工作记忆容量对汉语阅读理解有促进作用.(3)高工作记忆容量组比低工作记忆容量组不仅在阅读过程中产生了更多数量的自我解释,而且还更多地使用衔接和推理的解释模式. 相似文献

儿童的选择性学习是目前认知发展领域的热点问题。儿童在因果知识领域内的选择性学习(即选择性因果学习)对于回答儿童如何获取知识这个经典问题具有重要意义。儿童的选择性因果学习表现在对他人解释的辨别、评估与采纳上。他们会主动向可靠的信息提供者寻求解释, 并在接收回答后表现出选择性跟进反应。对于他人的回答, 年幼儿童不仅能根据言语线索辨别出解释性陈述, 还能依据解释的结构特征选择更好的陈述加以采纳, 年长儿童甚至可以从不同模式的解释中灵活地学习更适宜的因果知识。未来研究应深入关注解释的其它特征在儿童选择性因果学习中的作用, 进一步探讨选择性因果学习的认知机制。 相似文献

Although findings from cognitive science have suggested learning benefits of confronting errors (Metcalfe, 2017), they are not often capitalized on in many mathematics classrooms (Tulis, 2013). The current study assessed the effects of examples focused on either common mathematical misconceptions and errors or correct concepts and procedures on algebraic feature knowledge and solving quadratic equations. Middle school algebra students (N = 206) were randomly assigned to four conditions. Two errorful conditions either displayed errors and asked students to explain or displayed correct solutions and primed students to reflect on potential errors by problem type. A correct example condition and problem-solving control group were also included. Studying and explaining common errors displayed in incorrect examples improved equation-solving ability. An aptitude-by-treatment interaction revealed that learners with limited understandings of algebraic features demonstrated greater benefits. Theoretical implications about using examples to promote learning from errors are considered in addition to suggestions for educational practice. 相似文献

A common finding is that information order influences belief revision (e.g., Hogarth & Einhorn, 1992). We tested personal experience as a possible mitigator. In three experiments participants experienced the probabilistic relationship between pieces of information and object category through a series of trials where they assigned objects (planes) into one of two possible categories (hostile or commercial), given two sequentially presented pieces of probabilistic information (route and ID), and then they had to indicate their belief about the object category before feedback. The results generally confirm the predictions from the Hogarth and Einhorn model. Participants showed a recency effect in their belief revision. Extending previous model evaluations the results indicate that the model predictions also hold for classification decisions, and for pieces of information that vary in their diagnostic values. Personal experience does not appear to prevent order effects in classification decisions based on sequentially presented pieces of information and in belief revision. 相似文献

This contribution is a commentary to a special issue titled “Example-based learning: New theoretical perspectives and advances to a contemporary instructional approach” published in Applied Cognitive Psychology (2020). In the commentary, the presented research is discussed with respect to three extensions compared with previous research, namely, theoretical frameworks, learning scenarios and domains. It concludes with some suggestions for methodological advancements. 相似文献

The conception of appropriate models of information retrieval is a crucial step for the actual growth and development of the web. In addition to traditional information retrieval techniques, nowadays search engines have adopted methods for taking into account the social network deriving from the pattern of interconnections. Using different arguments, it has been shown that this is very effective in practice. In this paper we subscribe that point of view, but state also that social networks based ranking schemes operating on the whole web, like Google’s
, prevent small communities to become visible on the Web, regardless of the quality of the information. Hence, we strongly advocate the development of new cognitive models of the whole process of information retrieval which are capable of facing this problem. We give a picture of distributed architectures which incorporates topic-based intelligent agents and personal agents for capturing the user’s profile. 相似文献

The goals of this study are to evaluate a relatively novel learning environment, as well as to seek greater understanding of why human tutoring is so effective. This alternative learning environment consists of pairs of students collaboratively observing a videotape of another student being tutored. Comparing this collaboratively observing environment to four other instructional methods—one-on-one human tutoring, observing tutoring individually, collaborating without observing, and studying alone—the results showed that students learned to solve physics problems just as effectively from observing tutoring collaboratively as the tutees who were being tutored individually. We explain the effectiveness of this learning environment by postulating that such a situation encourages learners to become active and constructive observers through interactions with a peer. In essence, collaboratively observing combines the benefit of tutoring with the benefit of collaborating. The learning outcomes of the tutees and the collaborative observers, along with the tutoring dialogues, were used to further evaluate three hypotheses explaining why human tutoring is an effective learning method. Detailed analyses of the protocols at several grain sizes suggest that tutoring is effective when tutees are independently or jointly constructing knowledge: with the tutor, but not when the tutor independently conveys knowledge. 相似文献

样例学习研究表明多重样例的学习效果好于单个样例。然而研究者关于如何有效设计多重样例得出了不同的发现。通过综述已有关于多重样例学习的实证研究,总结出两个尚未得到解决的问题:(1)多重样例之间的相似或相异程度应该如何;(2)学生的先前知识在多重样例学习中的作用如何。针对已有研究的局限性,本文指出,具有不同先前知识的学生学习时感受到不同的关键属性,多重样例应该基于学生学习时的关键属性设计特定的变易范式以帮助学生学习。 相似文献
