教师成就目标的测量及其与学校目标结构的关系

首先,依据Elliot关于成就目标的能力界定标准和能力效价的理论构想,提出教师成就目标的理论结构。浙江省内外十多所中小学523份有效调查数据的探索性和验证性因素分析的结果表明,教师成就目标由6个因素构成,即:绝对-回避目标、个人-回避目标、参照-回避目标、个人-接近目标、参照-接近目标、绝对-接近目标。然后,利用浙江省内外另外十多所中小学625份调查问卷的结果,采用结构方程模型技术对教师成就目标和学校目标结构之间的关系进行了分析。结果表明,掌握目标结构对绝对-接近目标、个人-接近目标具有显著正效应,对绝对-回避目标具有显著负效应;成绩目标结构对绝对-接近目标、参照-接近目标、个人-回避目标和参照-回避目标具有显著正效应。     

采用跨学科概念图推进中学生跨学科学业成就

为了检验跨学科概念图在跨学科知识整合中的作用,设计了跨学科概念图干预计划,以180名中学生为被试,采用实验组与控制组对比实验方法,探讨了跨学科概念图对跨学科学业成就的影响。结果表明:(1)跨学科概念图干预计划显著提高了实验组被试的跨学科学业成绩;(2)对于不同成就者而言,干预计划显著提高了中低成就者的跨学科学业成绩,而对高成就者跨学科学业成绩的影响不显著。这意味着跨学科概念图作为跨学科知识整合领域的智力适应工具能够有效提高学习者的跨学科学业成就,但是其对不同层次学习者跨学科学业成就的影响具有适应性差异。     

垂直量尺化中的参数标定方法及其性能比较

在使用项目反应理论进行量尺化的语境下, 参数标定方法是垂直量尺化结果的一个至关重要的影响因素。目前的参数标定研究就部分标定方法的相对性能获得了较一致的结果, 就如何实现更佳量尺化也提出了很多新的标定方法。除了在既有框架内继续探索, 以形成完整的研究体系, 未来的研究应结合相关学科, 在深入了解学业增长的性质的基础上探究标定方法的性能, 并应考察特定的标定方法和特定的研究条件、量尺化语境之间的最佳匹配关系。     

Structuralism as a philosophy of mathematical practice

This paper compares the statement ‘Mathematics is the study of structure’ with the actual practice of mathematics. We present two examples from contemporary mathematical practice where the notion of structure plays different roles. In the first case a structure is defined over a certain set. It is argued firstly that this set may not be regarded as a structure and secondly that what is important to mathematical practice is the relation that exists between the structure and the set. In the second case, from algebraic topology, one point is that an object can be a place in different structures. Which structure one chooses to place the object in depends on what one wishes to do with it. Overall the paper argues that mathematics certainly deals with structures, but that structures may not be all there is to mathematics. I wish to thank Colin McLarty as well as the anonymous referees for helpful comments on earlier versions of this paper.     

Academic Achievement Over 8 Years Among Children Who Met Modified Criteria for Attention-deficit/Hyperactivity Disorder at 4–6 Years of Age

The predictive validity of symptom criteria for different subtypes of ADHD among children who were impaired in at least one setting in early childhood was examined. Academic achievement was assessed seven times over 8 years in 125 children who met symptom criteria for ADHD at 4–6 years of age and in 130 demographically-matched non-referred comparison children. When intelligence and other confounds were controlled, children who met modified criteria for the predominantly inattentive subtype of ADHD in wave 1 had lower reading, spelling, and mathematics scores over time than both comparison children and children who met modified criteria for the other subtypes of ADHD. In some analyses, children who met modified criteria for the combined type had somewhat lower mathematics scores than comparison children. The robust academic deficits relative to intelligence in the inattentive group in this age range suggest either that inattention results in academic underachievement or that some children in the inattentive group have learning disabilities that cause secondary symptoms of inattention. Unexpectedly, wave 1 internalizing (anxiety and depression) symptoms independently predicted deficits in academic achievement controlling ADHD, intelligence, and other predictors.     

概念图对学生成绩和态度影响的元分析

这个元分析评论了学生利用概念图进行学习的实验研究.首先按照元分析的标准选择文章,从涉及3623名被试的26项研究中抽取27个独立效果量.不同年级水平的学生应用概念图学习科学、心理学和统计学等课程的内容.后测评估了知识的唤起和迁移.在不同的教学条件、教学情境和方法中,应用概念图策略都使得学生的成绩增加、学生对学习的态度变得更加积极肯定、降低了学生对学习的焦虑.平均效果量依据概念图的使用方法和对照组的特点而改变,不同的研究存在显著的异质.     

学习态度与学习成绩的相关研究——以学习考勤记录与课堂提问成绩作为学生平时成绩的初步探讨

本研究以大学生的学习考勤记录与课常提问成绩作为其平时成绩的方法,对学习态度与学习成绩的相关进行了初步探讨.研究表明,由学习考勤记录与课堂提问成绩组成的平时成绩与学习总成绩呈现极其显著的相关,证明学习态度对学习成绩具有重要的影响,能在一定程度上对后者进行预测;同时,说明以学习考勤记录与课堂提问成绩作为平时成绩的方法,对于评估学生的学习态度和学习结果具有一定的可行性和有效性.     

Number words in young children's conceptual and procedural knowledge of addition, subtraction and inversion

Three studies addressed children's arithmetic. First, 50 3- to 5-year-olds judged physical demonstrations of addition, subtraction and inversion, with and without number words. Second, 20 3- to 4-year-olds made equivalence judgments of additions and subtractions. Third, 60 4- to 6-year-olds solved addition, subtraction and inversion problems that varied according to the inclusion of concrete referents and number words. The results indicate that number words play a different role in conceptual and procedural development. Children have strong addition and subtraction concepts before they can translate the physical effects of these operations into number words. However, using number words does not detract from their calculation procedures. Moreover, consistent with iterative relations between conceptual and procedural development, the results suggest that inversion acquisition depends on children's calculation procedures and that inversion understanding influences these procedures.
