The catcher in the lie: The role of emotions and epistemic judgments in changing students’ misconceptions and attitudes in a post-truth era

We extend previous theoretical and empirical work by examining the role that emotions and epistemic judgments play when learning from different refutation plus persuasive and expository plus persuasive texts. We examined how variations in messages designed to change misconceptions and attitudes about genetically modified foods (GMFs) might differentially impact the extent to which individuals engage in epistemic judgments; the emotions individuals experience during learning; and, how epistemic judgments and emotions might facilitate or constrain conceptual and attitudinal change. One hundred twenty-five undergraduate university students were randomly assigned to one of four text conditions: refutation plus positive persuasive text, refutation plus negative persuasive text, expository plus positive persuasive text, or expository plus negative persuasive text. Students were asked to think and emote out loud during learning to capture epistemic judgments and emotions as they occurred in real time. After the learning session, students also self-reported the emotions they experienced during learning. Results revealed that students who were given positive persuasive texts experienced more positive emotions (both intensity and frequency) during learning, whereas those who were given negative persuasive texts experienced more negative emotions (frequency) during learning. Students who were given positive persuasive texts engaged in more epistemic judgments and changed more misconceptions about GMFs compared to students in the other three text conditions. Finally, epistemic judgments were significant positive predictors of conceptual and attitudinal change, and both positive emotions and negative emotions predicted attitudinal change. Implications for theories of conceptual and attitudinal change are discussed.

论体育课程观的嬗变

本文认为在学校体育发展的过程中，重视强身健体作用的科学主义体育课程观脱胎于重视体育人文教化作用的人文主义体育课程观并与之并驾齐驱，20世纪加年代开始出现二者融合的趋势，新体育课程观应是以理解为基础的体育课程观。其理念对促进当前的体育课程改革具有一定的理论和实践意义。     

基于ontology的语义检索模型架构

目前的web信息检索中，存在着检索效率低下的问题，很难满足普通用户基于自然语言的检索要求，也不具备语义推理能力，无法实现智能化的检索。而源于知识工程和人工智能领域的本体理论和技术，能够很好地处理自然语言理解问题和具有基于语义的推理机制，因此成为改进传统信息检索方式的良好工具。本文就运用本体理论，在对目前的各种研究进行了调查以后，区别了几个关键的容易混淆的概念，然后提出了一个基于ontology的、web环境下的语义检索系统的结构模型。     

新闻形态论

新闻形态是指新闻的存在方式与状态。新闻的存在 ,无论是从新闻传播现象的历史过程看 ,还是从一次新闻传播的历时过程看 ,都有形态的演变。新闻形态论的提出 ,对从学术上厘清“新闻”概念的具体含义 ,实践上把握新闻传播的内在运作机制 ,都具有重要的启发意义     

Confidence in prior knowledge,self-efficacy,interest and prior knowledge: Influences on conceptual change

This study explored how confidence in prior knowledge, self-efficacy, interest, and prior knowledge interact in conceptual change learning. One hundred and sixteen college students completed an assessment of confidence in prior knowledge, self-efficacy, interest, prior scientific understanding, and prior misconceptions before reading a refutation text on seasonal change. Students’ misconceptions and scientific understanding of seasonal change was then assessed before and after reading a refutation text, and again at a two week delayed posttest. Three profiles of students emerged based on their confidence in prior knowledge, self-efficacy, interest, prior scientific understanding, and prior misconceptions. The profiles included: (1) Low (low confidence, self-efficacy, interest, and prior scientific understanding and high prior misconceptions), (2) mixed (high confidence, self-efficacy, and interest, but low prior scientific understanding and high prior misconceptions), and (3) high (high confidence, self-efficacy, interest, and prior scientific understanding and low prior misconceptions). Results indicated that the mixed profile appeared to be most productive for conceptual change and that learner characteristics most productive for conceptual change learning may differ from those most productive in other learning situations.     

小学四年级学生对平均数概念理解的发展过程

利用Pirie和Kieren提出的数学理解发展模型,分析了3名小学四年级学生对平均数概念理解的发展过程.结果表明:学生对平均数概念的理解经历了初步了解、产生表象、形成表象、关注性质和形式化等5个水平.在理解发展过程中,当学生发现他的思想和行动与自己所面临的问题不一致时,他就要折返回内层水平来扩展自己目前的活动能力和活动空间.而教师的干预则激发了学生的折返,为学生提供了独立建构或修正个人表象的机会.
