The influence of activity-based elementary science programs on classroom practices: A quantitative synthesis     

Ted Bredderman 《科学教学研究杂志》1984,21(3):289-303

The results of 11 studies of classroom practices used with the activity-based elementary science programs, ESS, SCIS, and SAPA, were combined quantitatively. All studies included control groups and employed techniques for coding lesson events. A composite category system was developed for combining study results. It was found that teachers using activity-based programs spent about 10% more time on student activity and 10% less time on talk than teachers using traditional methods. More direction giving, more higher level questions, and less lecturing were also reported. Teachers trained in program use spent less time giving directions, more time on activities, and less time on talk than untrained teachers using the programs. On the average, researchers coded slightly less student talk and slightly less student-initiated talk in activity-based classrooms.  相似文献   

Is Self‐worth Protection Best Regarded as Intentional Self‐handicapping Behaviour or an Outcome of Choking Under Pressure?     

Ted Thompson  Dale L. Dinnel 《教育心理学》2007,27(4):509-531

Self‐worth protective students characteristically perform poorly when they anticipate that poor performance is likely to reveal low ability, yet perform well in situations that involve little threat to self‐worth. The present study sought a further understanding of this variable pattern of achievement, assessing two possibilities: (1) that the poor performance of students high in self‐worth protection in situations of high evaluative threat is appropriately viewed as self‐handicapping behaviour in the form of strategic withdrawal of effort, and (2) that the poor performance of students high in self‐worth protection is an outcome of anxiety or “choking under pressure”. Participants were 72 undergraduate students, either high or low in self‐worth protection, assigned to one of three performance feedback conditions: humiliating failure, failure allowing face‐saving, and success. They subsequently completed 20 anagrams and 12 remote associates tasks, assessing performance, followed by 16 unicursal tasks during what was believed to be a practice period, providing an assessment of behavioural self‐handicapping in the form of intentional low effort. Students high in self‐worth protection performed poorly on the anagrams and remote associates following humiliating failure. They also reported greater anxiety across experimental conditions and claimed greater anxiety impairment than students low in self‐worth protection. These outcomes provide little support for an interpretation of self‐worth protection as self‐handicapping behaviour, instead supporting an interpretation of self‐worth protection as an outcome of choking under pressure, fuelled by evaluative threat.  相似文献   

Responding to the Message: providing a social context for children learning to write     

Helen Jerram  Ted Glynn  Bryan Tuck 《教育心理学》1988,8(1-2):31-40

Abstract In this classroom‐based research study, written expression was viewed as an interactive social process involving written communication between the teacher and the children. Children received increased opportunities to write on topics they chose themselves, and their teacher responded in writing to the content of their writing. The teacher did not provide corrective feedback for accuracy of spelling or grammar throughout the study. Written content feedback from the teacher was provided to each child according to an intra‐subject ABAB research design. Analysis of the teacher's written feedback identified her use of six specific categories of positive response to the themes, ideas and characters of each child's writing. Significant increases in both quantity and quality of writing occurred during the written content feedback phases. Spelling accuracy was maintained at a high level of accuracy throughout the study.  相似文献

Positive and negative contrast effects obtained following shifts in liquid sucrose reward in thirsty rats     

Mitri E. Shanab  John France  Ted Young 《Learning & behavior》1976,4(1):9-12

In a repeated shifts experiment four independent groups of thirsty rats received the following treatments: LSLS, LLLS, SSLS, and SSSS, with each letter denoting the magnitude (large or small) of sucrose reward received in each of the four phases of the experiment. While no negative contrast effect (NCE) was obtained in Phase 2, a very reliable positive contrast effect (PCE) was found in Phase 3. Moreover, a significant NCE was obtained in Phase 4. The results were explained in terms of the relative rather than absolute effects of reinforcement.  相似文献   

Teacher Factors and Special Class Referral Decisions     

Keri Wilton  Tony Cooper  Ted Glynn 《International Journal of Disability, Development & Education》1987,34(3):173-180

Using questionnaire data an examination was made of the personal and professional characteristics of 127 regular class (Grade 2‐5) teachers, all of whom had a child in their class whom they believed to be mildly retarded and not coping academically as well as socially in school. Of this group, 53 had referred the child to school psychological services while the remainder had not done so at the time of the study. A set of 28 variables derived from the questionnaire data was subjected to multiple regression analysis in order to examine the predictability of teachers’ referral decisions. Nine significant predictors were identified which together accounted for 35 percent of the variation in referral decisions. Inter‐group contrasts on these measures revealed that referring teachers were more likely to have made previous referrals, had better access to psychologists, were more confident of their ability to identify children who would qualify for special class admission, believed their school policy to b e more encouraging of referrals, were more likely to have made use of special programs, and received more frequent visits from psychologists. Results are discussed in terms of identifying “unserved mildly retarded” children in regular classes.  相似文献   

Childcare Workers’ Use of Talking Up and Incidental Teaching Procedures under Standard and Self‐management Staff Training Packages     

Helen Charles  Ted Glynn  Stuart McNaughton 《教育心理学》1984,4(3):199-212

Two childcare workers in a daycare setting were trained in the use of Talking Up and Incidental Teaching procedures, designed to increase children's language. Training was introduced in two stages. The first was a standard training package comprising oral and written instructions, roleplay, modelling and feedback. The second was a modified package comprising a self‐management component (the formulation by childcare workers of specific plans to implement each procedure, and a correspondence training component in which they received feedback on correspondence between their performance and their plans). Following a baseline period in which rates of child‐initiated language were monitored the standard training package was introduced for both Talking Up and Incidental Teaching. Next, the modified (self‐management) training package was introduced, first for Incidental Teaching, and subsequently for Talking Up. Introducing the standard training package resulted in markedly increased use of Talking Up by one worker and Incidental Teaching by both workers. However there was a concomitant decrease in child‐initiated language (and hence opportunities to use Incidental Teaching). When the modified (self‐management) package was introduced for Incidental Teaching, there was a resultant increase in the use of that procedure as well as a marked increase in child‐initiated language. When the modified (self‐management) package was introduced for Talking Up, there was a resultant increase in the use of that procedure but in contrast, there was a decrease in child‐initiated language. With the introduction of each training package, nevertheless, both workers responded to increased proportions of child initiations over baseline. Results are discussed in terms of the confounding effects of the two procedures in this study and their relative usefulness in improving child language.  相似文献

Urban school leadership for elementary science instruction: Identifying and activating resources in an undervalued school subject     

James P. Spillane  John B. Diamond  Lisa J. Walker  Rich Halverson  Loyiso Jita 《科学教学研究杂志》2001,38(8):918-940

This article explores school leadership for elementary school science teaching in an urban setting. We examine how school leaders bring resources together to enhance science instruction when there appear to be relatively few resources available for it. From our study of 13 Chicago elementary (K–8) schools' efforts to lead instructional change in mathematics, language arts, and science education, we show how resources for leading instruction are unequally distributed across subject areas. We also explore how over time leaders in one school successfully identified and activated resources for leading change in science education. The result has been a steady, although not always certain, development of science as an instructional area in the school. We argue that leading change in science education involves the identification and activation of material resources, the development of teachers' and school leaders' human capital, and the development and use of social capital. © 2001 John Wiley & Sons, Inc.
