中学生阅读理解元认知的发展研究 总被引:6,自引:0,他引:6
1 前言 阅读理解元认知是近二十多年来元认知研究的一个重要方面。国外对儿童阅读理解元认知的研究发现 ,年龄小和阅读能力差的读者在阅读理解监控方面比年龄大和能力好的读者差 ,而且好的读者比差的读者能更好地监控、调节自己的阅读活动 ,拥有更多的元认知知识和更高的元认知监控能力。Paris (1983)认为阅读过程中的元认知对阅读理解的影响主要以三种方式体现 ,即自我评价、自我计划和自我调节。目前 ,国内针对中学生阅读理解元认知的研究还很少 ,本研究试图从阅读理解元认知的这三方面探查中学生阅读理解元认知发展的特点 ,并了解不… 相似文献

学困生关于材料特征的元认知知识与应用的实验研究 总被引:4,自引:1,他引:3
本研究以62名学习困难学生(以下简称差生或学困生)和63名优生为被试,采用三因素混合实验设计,对优差生的阅读元认知知识及其应用特点进行了研究。结果表明:(1)优生对材料组织特征的元认知知识水平显著高于对词汇难度特征的元认知知识水平,而差生不存在显著差异;(2)九年级学生对材料组织特征的元认知知识水平显著高于词汇难度特征的元认知知识水平;其他年级之间没有显著差异;(3)在实际的阅读过程中,优生进行时间分配的人数显著多于学困生;学习困难学生的元认知知识与元认知控制的联系显著弱于优生。 相似文献

该文分析了强迫症患者在现实监控、知道感、元认知信念和责任控制等方面的研究,发现缺乏对不同类型强迫症元认知差异的研究、被试选取的典型性和代表型有待提高,现实监控障碍的身心原因尚不明确、责任-控制障碍形成的机制研究不足.指出元认知干预的强迫症治疗范式、强迫症与其他精神症元认知障碍的比较、强迫症元认知的认知神经科学探索和强迫性网络使用的元认知机制等是未来研究的趋势. 相似文献

1元认知的形成及功能[1]
元认知是指认知主体对自身认知活动的认知,包括元认知知识、元认知体验、元认知监控三个部分.元认知不是人天生就有的,而是在学习中从无到有、从低级到高级、从外控到内控、从局部到整体,逐步发展起来的.最初,个体毫无监控学习活动的经历与体验,当在他人指导下或无意识的自我监控获得成效后,可强化再次的体验与监控,从而逐步转化为自发的有意识地自我监控,但监控范围较窄,常为学习活动中的某一环节、某一侧面或某一学科内容.通过有意识地反复运用,这种自我观察、自我判断、自我控制逐渐变得娴熟起来,最终达到自动化的程度,其监控范围也从某一环节扩展到学习的整个过程,并可迁移到不同的学习内容上.由此可见,元认知是"对认知的认知",具有感知、调控自身认知能力的功能,与学习、创新等能力关系密切. 相似文献

The role of children's metacognitive knowledge in their mathematics strategy use was studied by a longitudinal examination of second graders' effort attributions, metacognition for mathematics, and strategy use while solving mathematics problems. Children's correct use of retrieval, internal and external strategies, and the prevalence of strategy use were assessed in September and the following January. Effort attributions for success and failure were also assessed at both points in time. In January, metacognitive knowledge about mathematics strategies was measured. Second graders possess metacognitive knowledge about mathematics strategies, and this knowledge is correlated most strongly with the tendency to use internal strategies in September and correct internal strategy use in September. Effort attributions measured at both timepoints were significantly related to metacognition. Effort attributions in January also correlated with the tendency to use internal strategies in January. In general, the results are consistent with self-system theories, which posit that metacognition, motivation, and strategy use work together to promote learning. 相似文献

根据Flavell的元认知理论框架,拟订了写作元认知教学的原则,并以此对两个班62名一年级大学生进行了一系列针对大学生英语写作元认知的教学活动。通过采用开放式问卷和周记调查,探究了在教学活动条件下大学生写作元认知的特点。周记调查表明:教学活动条件下,大学生的英语写作元认知特点反映出教学原则的构想,即英语写作元认知体现为元认知知识和元认知体验两大要素。元认知知识由任务知识、主体知识和策略知识构成,元认知体验分为积极与消极体验。开放式问卷结果表明:英语写作元认知有一定的发展性。这些结果验证并丰富了Flavell的元认知理论,对我国大学英语写作教学实践有着重要的启示。 相似文献

This study chronicles 10 undergraduate university students and their understanding and application of metacognition and executive control in reading. Students from two undergraduate reading classes from two different states received intensive instruction in metacognitive strategies which highlighted metacognition and executive control in the reading process. To document their understanding and application, students engaged in: 1) think-aloud analyses; 2) sharing of metacognition journals of their outside reading habits; and 3) developing metacognitive strategies. Additionally, the university students tutored young readers in order to apply their knowledge of activities learned in class and they kept a journal for all sessions. Finally, the university students responded to a case study that recommended reading activities and diagnostic teaching strategies for the young reader profiled in the case study. Results from the above data sources indicated that while university students understood and applied metacognitive strategies in their personal reading and were aware of these strategies that made them strategic readers, they applied little of these strategies to the tutoring and case study situations. These students appeared to operate under two definitions of the reading process witnessed through what they did and what they attempted to teach their tutees. 相似文献

元认知是对认知的认知, 包含认知的各个方面, 近年来元认知与面部认知的结合开始得到关注。两者结合切入点包括元认知错觉(达克效应和自我中心偏见)在面部认知中的适用性, 以及面部认知现象(异族效应和熟悉度优势)在元认知中的适用性。研究方法根据测量时间点和评估对象的选取而各有侧重。当前研究尚停留在元认知监测层面, 未来可扩展至面部认知的元认知控制、与机器学习结合等方向, 为理解面部认知提供新角度, 扩展其应用价值。 相似文献

Research on metacognition is reviewed and suggestions are made for application of this knowledge by school psychologists in assessment, intervention, and consultation. Two empirical studies illustrate the application of a specific metacognitive strategy — the think-aloud procedure—to assessment and intervention. The first study showed that asking students to give reasons for responses improved performance on a test of reading comprehension. The second study showed that incorporating the think-aloud technique in remedial reading instruction resulted in substantial gains in reading comprehension. 相似文献

元认知监控是元认知的核心成分,而且是内隐程度较高的心理活动。研究采用认知操作法,对经典的Mastermind游戏任务加以改编,结合访谈分析,探讨了适合考察元认知监控的任务难度和有效的元认知监控指标。研究结果发现:(1)对于大学生来说,在游戏4(要求从六种颜色中选出四种正确的颜色,且排列位置也要正确)中当知觉难度最大且又可以经过努力选择策略、根据反馈进行有效选择时,才会在最大程度上激发元认知监控,使得游戏成绩提高;(2)“监测时间”是元认知监测的有效测量指标,而“违背反馈次数”是元认知控制的有效测量指标。 相似文献

采用结构知识归因的方法,以学习判断和项目优先选择作为元认知监测和控制的指标,考察重量对元认知监控的影响是否是无意识的。被试学习粘贴在不同重量纸盒上的词对,进行学习判断(实验1)或项目选择(实验2),并报告其判断或选择的依据。结果:(1)重量影响学习判断和项目优先选择,相对于轻纸盒,被试给予重纸盒上的词对更高的JOL并优先选择重纸盒上的词对进行学习;(2)重量对学习判断的影响只发生在判断依据为猜测的情况下,重量对项目优先选择的影响只发生在判断依据为猜测和直觉的情况下。上述结果支持了元认知的具身性,并提示重量对元认知监控的影响可能是无意识的。 相似文献

元认知监控作为元认知的核心成分,是内隐程度较高的心理活动。研究采用认知操作法,以MasterMind游戏任务为载体,从执行功能中认知灵活性的角度,探讨了元认知监控的内部机制。结果发现:元认知监测对元认知控制的作用受到认知灵活性的调节作用。对于高认知灵活性的学生,元认知监测水平越高,元认知控制越好;对于低认知灵活性的学生,元认知监测水平的高低不会引起元认知控制水平的显著变化。研究结果表明,高认知灵活性的学生能根据元认知监测进行有效元认知控制,而低认知灵活性的学生其元认知监测水平的提高没有影响元认知控制。结合元认知监控与执行功能进行了讨论。 相似文献

In the last decade of research on metacognition, the literature has been focused on understanding its mechanism, function and scope; however, little is known about whether metacognitive capacity can be trained. The specificity of the potential training procedure is in particular still largely unknown. In this study, we evaluate whether metacognition is trainable through generic meditation training, and if so, which component of meditation would be instrumental in this improvement. To this end, we evaluated participants’ metacognitive efficiency before and after two types of meditation training protocols: the first focused on mental cues (Mental Monitoring [MM] training), whereas the second focused on body cues (Self-observation of the Body [SoB] training). Results indicated that while metacognitive efficiency was stable in MM training group, it was significantly reduced in the SoB group after training. This suggests that metacognition should not be conceived as a stable capacity but rather as a malleable skill. 相似文献
