本研究选取某省示范高中92名学生为被试,采用问题讨论、自学指导、边讲边议、实践探究常见的四种课堂教学模式,对不同认知方式学生进行物理课堂教学,其结果表明:教学内容难度高且结构松散,实验探究、问题解决模式更适用于场独立性认知方式的学生。教学内容难度小且内容翔实,自学指导模式更适用于场依存性学生。 相似文献

ObjectivesChildhood maltreatment (CM) and cognitive emotion regulation strategies (CERSs) may be important in alcohol craving and dependence in alcohol-dependent individuals. The aim of this study was to evaluate direct effects of CM on the subscales of alcohol craving and alcohol dependence and its indirect effects via CERSs in individuals with a diagnosis of alcohol dependence.MethodsIn a cross-sectional design, 329 alcohol-dependent males completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Cognitive Emotion Regulation Questionnaire-Short version (CERQ-Short), the Alcohol Dependence Scale (ADS), the Obsessive Compulsive Drinking Scale (OCDS), and the Beck Depression Inventory-II (BDI-II).ResultsParticipants with alcohol dependence had early age of onset of alcohol use (mean = 20.78 years), relatively long duration of alcohol use (mean = 11.14 years), and low education (mean = 9.55 years). Indirect effects were observed from CM to the subscales of alcohol craving and dependence only through maladaptive CERSs after adjusting for demographic and clinical factors. No direct effect was observed through CM on the subscales of alcohol craving and dependence.ConclusionsAlthough drawing causal conclusions from the current research is impossible, the findings suggest that maladaptive CERSs may be a possible mechanism relating CM to alcohol craving and dependence in treatment-seeking alcohol-dependent individuals, while adaptive CERSs may be less important regarding this relation. However, the findings of the current study need longitudinal research. 相似文献

Virtual reality (VR) is predicted to create a paradigm shift in education and training, but there is little empirical evidence of its educational value. The main objectives of this study were to determine the consequences of adding immersive VR to virtual learning simulations, and to investigate whether the principles of multimedia learning generalize to immersive VR. Furthermore, electroencephalogram (EEG) was used to obtain a direct measure of cognitive processing during learning. A sample of 52 university students participated in a 2 × 2 experimental cross-panel design wherein students learned from a science simulation via a desktop display (PC) or a head-mounted display (VR); and the simulations contained on-screen text or on-screen text with narration. Across both text versions, students reported being more present in the VR condition (d = 1.30); but they learned less (d = 0.80), and had significantly higher cognitive load based on the EEG measure (d = 0.59). In spite of its motivating properties (as reflected in presence ratings), learning science in VR may overload and distract the learner (as reflected in EEG measures of cognitive load), resulting in less opportunity to build learning outcomes (as reflected in poorer learning outcome test performance). 相似文献

问题乃是通向理解之门.问题可以激发学习者的求知欲和探究欲,有利于推动教学的开展和促进学习者认知能力的发展.在线学习环境下为促进学习者认知能力的发展提供了丰富的认知工具和资源.但是,由于缺乏对教学问题导向作用的关注,在线课程在促进学习者认知能力发展方面存在着不理想之处,不能有效地引起认知上的深度理解.在文献研究和案例分析的基础上,综合分析了国内外问题导向在在线学习课程中的经验与不足,构建了问题导向促进学习者认知能力发展的在线学习框架和课程实例.在课程设计中提供了以问题为引导的情境体验和探究互动的机会,通过丰富的案例学习和认知支架,让学习者在问题解决过程中学会自主探究和深度思考,引导学习者从对知识的低水平认知层次逐渐向高水平认知层次发展.最后,为了验证问题导向在线课程对学习者认知发展的促进作用,采用实验调查等方法进行了实证研究. 相似文献

比类思维源于先秦,就“类”而言,中国的“类”概念,外延宽泛,中国比类思维散见在先秦诸子文献中,中国在先秦时就有了隐喻,究其发端,在比类思维。比类促生隐喻、促进认知、更助推了先秦灿烂辉煌的历史文化。 相似文献

The interactions between levels of learner prior knowledge and effectiveness of different instructional techniques and procedures
have been intensively investigated within a cognitive load framework since mid-90s. This line of research has become known
as the expertise reversal effect. Apart from their cognitive load theory-based prediction and explanation, patterns of empirical
findings on the effect fit well those in studies of Aptitude Treatment Interactions (ATI) that were originally initiated in
mid-60s. This paper reviews recent empirical findings associated with the expertise reversal effect, their interpretation
within cognitive load theory, relations to ATI studies, implications for the design of learner-tailored instructional systems,
and some recent experimental attempts of implementing these findings into realistic adaptive learning environments. 相似文献

Previous studies have distinguished cognitive, occupational status and network mechanisms in the relation between education and ethnocentrism. Hypotheses on these mediating mechanisms are derived from socialization theory, realistic group threat and contact theory. In the current study we use structural equation modeling to investigate the explanatory power of these three mechanisms simultaneously. The analysis is based on a representative population survey from the Netherlands (NELLS 2009, n = 1910). The results show that more than half of the initial association between education and ethnocentrism can be attributed to cognitive ability and occupational status mechanisms. The remaining part of the overall association, however, still has to be modeled as a direct relationship between education and ethnocentrism. This direct association can be attributed either to social desirability or to a direct liberalizing effect of education on social and political attitudes. Our analysis tentatively suggests that the rise of average education levels in Western societies might lead to less ethnocentric attitudes via the cognitive sophistication mechanism. 相似文献

Argument–counterargument integration (Nussbaum, 2008) refers to the process of evaluating, refuting, and synthesizing arguments on two sides of an issue when creating justification for an overall conclusion. This study compared the cognitive load of two critical thinking strategies related to argument–counterargument integration: (a) constructing design claims that minimize disadvantages of an alternative, and (b) weighing refutations (which weaken an argument by arguing that there are more important values at stake). College students (N = 285) first completed the Need for Cognition (NFC) scale and were then presented with materials summarizing arguments and counterarguments on the topic of grading class participation. Participants completed a small, integrative essay justifying a stand on the issue, and completed the Mental Effort Rating Scale (Paas, 1992). Participants who generated complex weighing refutations reported more mental effort than those constructing complex design claims (and the control group), with a stronger relationship with those high in NFC. The need to coordinate disparate elements in working memory may explain the higher load associated with constructing weighing refutations. Students may need more (and different types of) scaffolding in using this strategy than when constructing a design claim, which is a more sequential process. 相似文献
