Critical Thinking Disposition and Scientific Creativity: The Mediating Role of Creative Self-Efficacy

This study explores the relationship between critical thinking disposition and scientific creativity and examines the hypothesized mediating role played by creative self-concept (trait-like creative self-efficacy). A large sample (N = 1,153) of Chinese high school students filled the Critical Thinking Disposition Inventory and revised trait-like creative self-efficacy scale, and then solved Scientific Creativity Test for Adolescent. Structural equation modeling has demonstrated that students’ critical thinking disposition was positively related to their creative self-concept and scientific creativity, and creative self-concept fully mediated the link between critical thinking disposition and scientific creativity. We discuss these findings in terms of the hypothetical role played by creative self-concept for creative functioning.     

Curiosity-driven recommendation strategy for adaptive learning via deep reinforcement learning

The design of recommendation strategies in the adaptive learning systems focuses on utilizing currently available information to provide learners with individual-specific learning instructions. As a critical motivate for human behaviours, curiosity is essentially the drive to explore knowledge and seek information. In a psychologically inspired view, we propose a curiosity-driven recommendation policy within the reinforcement learning framework, allowing for an efficient and enjoyable personalized learning path. Specifically, a curiosity reward from a well-designed predictive model is generated to model one's familiarity with the knowledge space. Given such curiosity rewards, we apply the actor–critic method to approximate the policy directly through neural networks. Numerical analyses with a large continuous knowledge state space and concrete learning scenarios are provided to further demonstrate the efficiency of the proposed method.     

Wandering eyes: Eye movements during mind wandering in video lectures

Video lectures are increasingly prevalent, but they present challenges to learners. Students' minds often wander, yet we know little about how mind wandering affects attention during video lectures. This paper presents two studies that examined eye movement patterns of mind wandering during video lectures. In the studies, mind wandering reports were collected by either self-caught reports or thought probes. Results were similar across the studies: mind wandering was associated with an increased allocation of fixations to the instructor's image. For fixations on the slides, the average duration increased but the dispersion decreased. Moreover, preliminary evidence suggested that fixation duration and dispersion can diminish soon after self-caught reports of mind wandering. Overall, these findings help advance our understanding of how learners' attention is affected during mind wandering and may facilitate efforts in objectively identifying mind wandering. Future research is needed to determine if these findings can extend to other instructional formats.     

分心抑制和关系整合对学前儿童类比推理的影响

为探究分心抑制和关系整合对学前儿童类比推理的影响,实验一先初步探究分心抑制和关系整合对25名3~4岁和26名5~6岁儿童完成含有知觉分心的类比情景任务的影响。其次,揭示知觉分心与关系整合在类比推理中的具体作用模式。实验二先初步探究分心抑制和关系整合对30名3~4岁和28名5~6岁儿童完成含有语义分心的类比情景任务的影响。其次,揭示语义分心与关系整合在类比推理中的具体作用模式。结果表明,抑制控制能显著预测儿童完成各种类型类比推理成绩,工作记忆能显著预测儿童完成含有语义分心的类比推理成绩而不能显著预测含有知觉分心的类比推理成绩。儿童完成类比情景中的分心抑制是在关系整合中完成的,当类比情景中的关系整合没有超过儿童的工作记忆容量时,知觉或语义分心才能造成对儿童类比推理的影响。     

Children's knowledge of the earth: a new methodological and statistical approach

In the field of children’s knowledge of the earth, much debate has concerned the question of whether children’s naive knowledge—that is, their knowledge before they acquire the standard scientific theory—is coherent (i.e., theory-like) or fragmented. We conducted two studies with large samples (N = 328 and N = 381) using a new paper-and-pencil test, denoted the EARTH (EArth Representation Test for cHildren), to discriminate between these two alternatives. We performed latent class analyses on the responses to the EARTH to test mental models associated with these alternatives. The naive mental models, as formulated by Vosniadou and Brewer, were not supported by the results. The results indicated that children’s knowledge of the earth becomes more consistent as children grow older. These findings support the view that children’s naive knowledge is fragmented.     

马克思主义关于农业经济形态理论的新发展——读考茨基《土地问题》和列宁《土地问题笔记,1901-1915年》

在史学界对西方农业史的研究中,我国相当一部分学者仍然是按照马克思在19世纪中期前后从对英国农业分析中得出的某此结构去理解西方农业史的发展规律,这种规律以"两极分化"和"小农的消灭"为主要内容.     

宗教理解和宗教多元论问题

我们几乎都能肯定,诸宗教之问或多或少都有"排他"倾向,认为真理掌握在自己的手里,其他宗教信仰或多或少是错误的.一般宗教都在宣传自己的优越性,为自己的存在合理性寻找依据,即使是那些自认为是"非宗教的宗教"也是如此.     

高二理科生物理问题创造性解决的表象特征研究

物理问题创造性解决是一个发散思维和聚合思维交替运行的过程,而表象对问题的创造性解决具有重要作用。本研究通过自编的物理问题对天津市某中学109名高二理科学生进行物理问题创造性解决测验,探讨高中理科学生物理问题创造性解决中的表象特征。验证了表象与物理问题创造性解决中的发散思维具有显著的正相关,与聚合思维无显著相关。对109名高二理科学生K聚类分析发现：物理问题解决过程中,高创造性和中等程度创造性的学生人数较少,而低创造性的学生人数较多;表象丰富性很高和较高的学生较少,表象丰富性较低的学生较多。     

汉语双字词超音段信息在语义激活中的作用

采用眼动方法,通过两个实验考察了汉语双字词超音段信息在语义激活中的作用。结果显示：（1）汉语双字词语义激活过程中,分别改变首字声调和尾字声调对语义激活起到抑制作用,首字声调改变时的抑制作用更大。结果支持了Cohort模型。（2）语义相关词的注视点和注视时间远远多于其控制词,但没有发现词频效应。（3）汉语声调的加工过程与声韵母一样,独立作用于语义激活过程。     

书面韵律边界与语境对歧义句歧义消解的影响

本研究采用眼动记录的方法,考察了被试理解层次分隔歧义句时,作为书面韵律边界的逗号起到的作用,以及逗号与语境信息间的交互作用。实验通过操纵逗号的位置,变化歧义句的句义;通过操纵语境内容,变化语境偏向与逗号解歧方向的一致性。结果发现,逗号做为书面的韵律边界促进了句子的加工。当有书面韵律边界为句子解歧时,被试更依赖于韵律边界。语境信息与书面韵律边界的交互作用发生于句子加工晚期。
