Children's skill in making predictions and their understanding of what predicting means: A developmental study     

Margaret McNay  Kathleen W. Melville 《科学教学研究杂志》1993,30(6):561-577

The purpose of this study was to describe the development of elementary students' skill in making predictions and of their understanding of what predicting means. The study involved observing and assessing the performance of 167 children on the Physical Manipulation Test (PMT), a test involving the manipulation of science materials and equipment. Children were interviewed about what they understand predicting to mean, how they use it at school and at home, and why they think it is important. For each of the seven topics tested, even the youngest children were able to offer predictions. Accuracy varied with the topic, increasing between Grades 1 and 4 and leveling off after that. The increase in skill involved children's growing ability to attend to patterns discerned through their own observations. Four levels in the development of predicting skill, as it relates to particular topics, are described. Children's understanding of predicting showed steady improvement through Grade 6. Children's awareness of their use of predicting at school and at home, and their ability to explain the importance of predicting, also increased through Grades 1 to 6, with a spurt at Grade 4. Children understood predicting to be an internal process in which one uses knowledge to anticipate a future event; they regarded predicting as an important way of being intellectually involved with the world.  相似文献   

Children are not Meant to be Studied …     

W. A. HART 《Journal of Philosophy of Education》1993,27(1):17-27

The project of studying children in order to understand them, which lies at the heart of contemporary thinking about children and their education, is misconceived. It rests, jrst of all, upon a false belief that we can only come to know something properly by deliberately and systematically pursuing knowledge of it. Secondly, it offers a paradigm of knowing children which justifies parents and teachers in not giving themselves to children. By re-interpreting the problems that adults experience with children as technical, as arising from lack of information about them, it ignores the personal and moral dimension of adults' relations with children and thus further alienates them from one another.  相似文献

融资制度运行机制的政府主导特征分析     

郭栋 《河南师范大学学报(哲学社会科学版)》2006,33(1):88-91

多年市场化导向的改革使中国许多领域成功地摆脱了计划经济,市场机制对资源配置正在发挥基础作用,但在一些关键领域仍然由国家进行调控,转型经济中融资制度的运行机制就属于这些关键领域。由于国家对计划经济手段的路径依赖以及行之有效的市场手段的缺乏等原因,融资制度的运行机制呈现出典型的政府主导特征,集中表现为信贷计划(信贷总量控制)、价格控制、准入控制和其他直接控制的工具等手段仍发挥着强势作用。  相似文献   

Extending validity evidence for multidimensional measures of coaching competency     

Myers ND  Wolfe EW  Maier KS  Feltz DL  Reckase MD 《Research quarterly for exercise and sport》2006,77(4):451-463

This study extended validity evidence for multidimensional measures of coaching competency derived from the Coaching Competency Scale (CCS; Myers, Feltz, Maier, Wolfe, & Reckase, 2006) by examining use of the original rating scale structure and testing how measures related to satisfaction with the head coach within teams and between teams. Motivation, game strategy, technique, and character building comprised the dimensions of coaching competency. Data were collected from athletes (N = 585) nested within intercollegiate men's (g = 8) and women's (g = 13) soccer and women's ice hockey (g = 11) teams (G = 32). Validity concerns were observed for the original rating scale structure and the predicted positive relationship between motivation competency and satisfaction with the coach between teams. Validity evidence was offered for a condensed post hoc rating scale and the predicted relationship between motivation competency and satisfaction with the coach within teams.  相似文献

What Assessment and Research Say About the Condition of Education     

Gerald W. Bracey 《Educational Measurement》1992,11(4):5-6

Do students today know less than their parents or grandparents did as students? Are they being academically outclassed by students of other nations? Or have ideologically driven policy makers painted an unnecessarily negative picture of student achievement?  相似文献   

Chaos theory, informational needs, and natural disasters   总被引：2，自引：0，他引：2  

Timothy L. Sellnow  Matthew W. Seeger  Robert R. Ulmer 《Journal of Applied Communication Research》2002,30(4):269-292

This study applies chaos theory to a system-wide analysis of crisis communication in a natural disaster. Specifically, we analyze crisis communication during the 1997 Red River Valley flood in Minnesota and North Dakota. This flood, among the worst in modern American history, consumed entire metropolitan areas, displacing thousands of people. The conditions and decisions leading to the disaster, and the subsequent reactions are retraced. Communication related to river crest predictions (fractals), the shock at the magnitude of the crisis (cosmology episode), novel forms of reorganizing (self-organization), and agencies that aided in establishing a renewed order (strange attractors) are evaluated. Ultimately, we argue that preexisting sensemaking structures favoring rationalized, traditional views of a complex system led officials to make inappropriately unequivocal predictions and ultimately diminished the effectiveness of the region's crisis communication and planning.  相似文献
