本研究综合运用情境观察法、作品分析法对大班幼儿合作编制图书活动过程及其特点展开研究,结果发现:在大班幼儿合作编制图书活动中,幼儿的合作类型可以分为平行型、交互型、领导型和冲突型,其中领导型合作小组的合作效果优于其他类型;幼儿的合作水平可以分为形式化水平、松散性水平、组织化水平,其中组织化水平的合作小组制作出来的图画书内容水平最高;整体而言,大班幼儿在没有教师指导的情况下,合作编制的图画书水平偏低;合作类型、合作水平都与作品内容水平显著相关,但是与作品的结构水平无关.合作编制图画书活动对于大班幼儿来说是一个颇具难度和挑战的任务,是一种落在大班幼儿"最近发展区"的活动.教师首先需要在幼儿合作确立故事主题和创编故事时提供一定的支架,让幼儿意识到合作编制图画书时需要有共同的主题及故事,并引导幼儿围绕主题和故事进行讨论协商,而后在幼儿合作编制图画书的具体过程中能够针对不同合作类型小组的特点进行个别化指导. 相似文献

<正>在幼儿园中,科学活动可划分为观察认识、实验操作、科学制作、讨论探究、种植饲养等,无论是什么样的内容和形式,“思维表征”都是科学活动中非常重要的探究策略。“思维表征”就是让幼儿思维可视化的过程,幼儿通过图画、符号、动作或语言等把观察对象或事物之间的异同和联系“具象化”,从而构建科学经验,形成科学思维。本文以大班“制作PVC管汤桶架”为例,探讨如何以思维表征策略,支持幼儿科学制作活动的有效开展。 相似文献

幼儿图画故事是幼儿喜爱的早期阅读材料之一,它以特殊的表现形式和丰富的图文内容带给幼儿视听享受。图画故事需要成人参与讲述,需要成人与幼儿进行面对面近距离的交流。成人参与图画故事的阅读与讲述,挖掘图画故事的细节,掌握讲述的技巧和策略,才能在幼儿言语能力的成长中发挥最大价值。 相似文献

This study examined student actions, interpretations, and language in respect to questions raised regarding tabular, graphical, and algebraic representations in the context of functions. The purpose was to investigate students’ interpretations and specific ways of working within table, graph, and the algebraic on notions fundamental to a conceptualization of linear functions. Through a case study method which investigated individual representations and student articulations within them, the study revealed that students can make a transition from a given representation of linear function to another and yet demonstrate limited understanding of linear functions. 相似文献

In this digital ITEMS module, Nikole Gregg and Dr. Brian Leventhal discuss strategies to ensure data visualizations achieve graphical excellence. Data visualizations are commonly used by measurement professionals to communicate results to examinees, the public, educators, and other stakeholders. To do so effectively, it is important that these visualizations communicate data efficiently and accurately. These visualizations can achieve graphical excellence when they simultaneously display data effectively, efficiently, and accurately. Unfortunately, measurement and statistical software default graphics typically fail to uphold these standards and are therefore not suitable for publication or presentation to the public. To illustrate best practices, the instructors provide an introduction to the graphical template language in SAS and show how elementary components can be used to make efficient, effective, and accurate graphics for a variety of audiences. The module contains audio-narrated slides, embedded illustrative videos, quiz questions with diagnostic feedback, a glossary, sample SAS code, and other learning resources. 相似文献

In young children's counting,procedures precede principles 总被引：1，自引：0，他引：1
Robert S. Siegler 《Educational Psychology Review》1991,3(2):127-135
A substantial body of data on young children's counting is now available. Portions of these data can be explained by social context interpretations, such as those advanced by Elbers, but other parts of the data cannot be. The most urgent need is for models that illuminate how primitive conceptual understanding of cardinality and ordinality contributes to learning of counting procedures, and how experience with the counting procedures, in turn, enriches children's conceptual understanding. 相似文献

We describe and analyze a situation involving symbolic representation and graphical visualization of the solution of a system
of two linear differential equations, using a computer algebra system. Symbolic solution and graphical representation complement
each other. Graphical representation helps to understand the behavior of the symbolic solution. Together with it, the symbolic
solution and its analysis are needed to understand the graphical representation and to overcome the limiting constraints of
the CAS. The study described in this paper points out the importance of flexibility in building connections between different
mathematical registers, together with the fact that the balance between the usage of symbolic representations and of graphical
representations can be very different from one student to the other.

A procedure for checking the score equivalence of nearly identical editions of a test is described. This procedure is used early in the score equating process to help determine whether it is necessary to conduct separate equating analyses (using a variety of equating methods) for the two nearly identical versions of the test. The procedure employs the standard error of equating and utilizes graphical representation of score conversion deviation from the identity function in standard error units. Two illustrations of the procedure involving Scholastic Aptitude Test (SAT) data are presented. Advice about what to do if statistical equivalence does not obtain is given in the discussion section. Alternative strategies for assessing score equivalence are also discussed. 相似文献

Item analysis is an integral part of operational test development and is typically conducted within two popular statistical frameworks: classical test theory (CTT) and item response theory (IRT). In this digital ITEMS module, Hanwook Yoo and Ronald K. Hambleton provide an accessible overview of operational item analysis approaches within these frameworks. They review the different stages of test development and associated item analyses to identify poorly performing items and effective item selection. Moreover, they walk through the computational and interpretational steps for CTT‐ and IRT‐based evaluation statistics using simulated data examples and review various graphical displays such as distractor response curves, item characteristic curves, and item information curves. The digital module contains sample data, Excel sheets with various templates and examples, diagnostic quiz questions, data‐based activities, curated resources, and a glossary. 相似文献

Recent research on the phenomenon of improper proportional reasoning focused on students’ understanding of elementary functions and their external representations. So far, the role of basic function properties in students’ concept images of functions remained unclear. We add to this research line by investigating how accurate students are in connecting functions to their corresponding properties and how this accuracy depends on function types and representations. A large group of 10th graders evaluated for different function types, represented in either a graphical, a formulaic, or a tabular mode, the correctness of statements about their general properties and behavior. Results show that students succeeded rather well in making the right connections between properties and functions. Errors depended not only on the type of function for which the properties were evaluated but also on the kind of representation in which the function was presented. These results highlight the importance of function properties in students’ concept images of functions and suggest positive effects of making these properties explicit to students. 相似文献

Children's Narrative Representations of Mothers: Their Development and Associations with Child and Mother Adaptation 总被引：1，自引：1，他引：1
We investigated associations between children's representations of mothers in their play narratives and measures of children's and mother socioemotional adaptation, and explored the development of these representations between the ages of 4 and 5 years. Fifty-one children were interviewed using the MacArthur Story-Stem Battery to obtain their narrative representations of mothers. Positive, Negative, and Disciplinary representation composites were generated. Children who had more Positive and Disciplinary representations and fewer Negative representations had fewer behavior problems and their mothers reported less psychological distress. In addition, 5-year-olds had more Positive and Disciplinary representations and fewer Negative representations did 4-year-olds, and there was moderate stability in individual differences in children's representations of mothers across the 2 ages. The results add an important dimension to research on parent-child relationships—that of children's perspectives on these relationships. 相似文献
