Enhancement of pigeons’ conditional discrimination performance by expectancies of reinforcement and nonreinforcement     

Gail B. Peterson  Ruth L. Wheeler  Milton A. Trapold 《Learning & behavior》1980,8(1):22-30

Prior work has shown that when the separate correct responses of a conditional discrimination are followed by different reinforcing outcomes, performance is enhanced relative to that obtained under the conventional, single-reinforcer procedure. Four experiments with pigeons yielded the analogous finding when the different outcomes were reinforcement and explicit nonreinforcement. Controls indicated that the results could not be attributed to the effects of intermittent reinforcement, to possible differences in cue duration, or to a variety of potential sources of conditioned reinforcement. An interpretation in terms of expectancy learning is proposed.  相似文献   

Professors' and students' conceptualizations of the learning task in introductory physics courses     

Janet Gail Donald 《科学教学研究杂志》1993,30(8):905-918

What are students expected to learn in physics courses? Eight expert physics teachers and researchers, two from the University of Western Ontario in Canada, Cambridge University in the United Kingdom, Stanford University in the United States of America, and Monash University in Australia, described their perceptions of learning in their courses. Students from the courses were then interviewed for their perceptions of learning in physics courses. In their courses, professors focused on the development of intellectual skills, assuming that students had a specific physics vocabulary. Students, however, were aware of their own limitations and suggested that professors should take nothing for granted. Students considered that to be a good teacher, a professor should know the perspective of the students and should start at the students' level. The results suggested that the intellectual challenge of learning physics merits early explanation.  相似文献

SeeWord—a personal word processing environment for dyslexic computer users     

Peter Gregor  Anna Dickinson  Alison Macaffer  Peter Andreasen 《British journal of educational technology : journal of the Council for Educational Technology》2003,34(3):341-355

SeeWord is a highly configurable word processing environment, which assists dyslexic users when producing and reading text. The software was developed using a user-centred development cycle where user feedback contributed to each revision. Evaluations showed that users were able to find individualised combinations of settings using the specialised software, which they used in preference to the black-on-white text that is usually displayed on computer monitors. Three separate prototypes of the software were developed and evaluated. The third prototype was used in an experimental study with 6 dyslexic school pupils. The research showed that 5 out of the 6 dyslexic users aged 14–16 years benefited from the use of specialised software when reading text from a computer screen. Participants were able to read standard texts from a screen significantly more accurately with the aid of SeeWord. All participants reported that they felt they could read text from the screen better using the software. The results suggest that a larger scale evaluation of the software would provide valuable information about problems associated with computer use by people with dyslexia. A further study into the visual processes involved in dyslexia would also be of great value.  相似文献   

Children''s Use of Anatomically Detailed Dolls to Recount an Event   总被引：2，自引：0，他引：2  

Gail S. Goodman  Christine Aman 《Child development》1990,61(6):1859-1871

The use of anatomically detailed dolls in child sexual abuse investigations has raised several controversial issues related to important theoretical questions in developmental psychology. The present study was designed to examine some of these issues in a methodologically sound experiment. 80 3- and 5-year-old children experienced a social interaction with a male confederate and were later tested under 1 of 4 recall conditions: reenactment with anatomically detailed dolls, reenactment with regular dolls, free recall with visual cues, or free recall without visual cues. The children were also asked a variety of specific and misleading questions, some of them dealing with acts associated with abuse ("He took your clothes off, didn't he?"). Both anatomically detailed and regular dolls along with other props aided 5-year-olds more than 3-year-olds in recounting the event. To use increased rather than decreased age differences. Anatomically detailed dolls did not foster false reports of abuse. Overall, 3-year-olds were more suggestible than 5-year-olds. The findings have implications for children's testimony in child abuse cases and for psychological theories concerning the effects of stimulus support on children's memory.  相似文献   

Receptive Language of Gifted and Learning Disabled‐Gifted Children     

Gail D. Chermak  Donna M. Burgerud 《International Journal of Disability, Development & Education》1983,30(3):226-229

Three tests of receptive language were administered to thirty children enrolled in regular, gifted, and learning disabled‐gifted programs. Analyses of variance indicated that the Token Test for Children differentiated the learning disabled‐gifted children and the Verbal Absurdities Subtest of the Detroit Tests of Learning Aptitude differentiated the gifted children from the other two groups.  相似文献   

Reading and spelling difficulties in high school students: Causes and consequences     

Donald Shankweiler  Eric Lundquist  Lois G. Dreyer  Cheryl C. Dickinson 《Reading and writing》1996,8(3):267-294

Basic skills in reading and spelling and supporting metalinguistic abilities were assessed in ninth and tenth grade students in two school settings. Students attending a private high school for the learning disabled comprised one group and the other comprised low to middle range students from a public high school. Both the LD students and the regular high school students displayed deficiencies in spelling and in decoding, a factor in reading difficulty that is commonly supposed to dwindle in importance after the elementary school years. Treating the overlapping groups as a single sample, multiple regression analysis was used to investigate the contribution of nonword decoding skill and phonological and morphological awareness to spelling ability. The analysis revealed that decoding was the major component, predicting about half of the variance in spelling. The effect of phonological awareness was largely hidden by its high correlation with decoding, but was a significant predictor of spelling in its own right. Morphological awareness predicted spelling skill when the words to be spelled were morphologically complex. An additional study showed that differences in decoding and spelling ability were associated with differences in comprehension after controlling for reading experience and vocabulary. Even among experienced readers individual differences in comprehension of text reflect efficiency of phonological processing at the word level.  相似文献   

Preschool children's reasoning about ability   总被引：3，自引：0，他引：3  

Heyman GD  Gee CL  Giles JW 《Child development》2003,74(2):516-534

Young children's reasoning about ability was investigated among 155 preschoolers (M = 4 years, 10 months) across 3 studies. Results suggest that preschoolers are sensitive to mental state information when making judgments about another child's ability: They judged a child who finds a task easy to be smarter than one who finds the same task hard. Systematic patterns of errors on recall tasks suggest that preschoolers perceive positive correlations between (a) exerting effort and experiencing academic success, and (b) being nice and having high academic ability. Results from a comparison group of forty 9- to 10-year-olds (M = 9 years, 10 months) suggest that the preschool findings generally reflect emerging patterns of reasoning about ability that persist into later childhood, but that the perceived correlations between high effort and academic outcomes and between social and academic traits diminish with age.  相似文献   

Learning at the nanoscale: The impact of students' use of remote microscopy on concepts of viruses,scale, and microscopy     

M. Gail Jones  Thomas Andre  Richard Superfine  Russell Taylor 《科学教学研究杂志》2003,40(3):303-322

The rapid pace of development is bringing advanced technologies to the World Wide Web (WWW), and, as a result, schools have access to new tools for science investigations. In this exploratory study, we investigated how an educational experience organized around students' use of a WWW‐controllable atomic force microscope (AFM) influenced students' understandings of viruses. The context for the study was a weeklong unit on viruses for two high school biology classes which incorporated student use of the WWW controllable AFM. We also investigated how the haptic (involving kinesthetics and touch) experiences afforded by this tool might influence students' knowledge of viruses, microscopy, and nanometer scale. Fifty students from two high school biology classes participated in a series of instructional activities and pre‐ and postassessments (knowledge test, opinion questionnaire, and interviews). Results showed that students' understandings of microscale, virus morphology, and dimensionality changed as a result of the experiences. Students' conceptions moved from a two‐dimensional textbook‐like image of a virus to a three‐dimensional image of an adenovirus. The results of this preliminary study suggest that the use of the technology as a tool for learning about morphology of materials too small to see may be beneficial. © 2003 Wiley Periodicals, Inc.

Development and Evaluation of an Inquiry-Based Elementary Science Teacher Education Program Reflecting Current Reform Movements   总被引：1，自引：0，他引：1  

Gail R. Luera  Charlotte A. Otto 《Journal of Science Teacher Education》2005,16(3):241-258

The National Science Education Standards (National Research Council 1996, National science education standards. Washington, DC: National Academy Press) and various other national and state documents call for teachers who possess science content knowledge, employ an inquiry approach in teaching, and engage in reflective practices. This paper describes a rationale for choosing particular recommendations to implement and how we incorporated those as we revised our elementary science education program. An analysis of the impact of the reformed inquiry-based content courses revealed that students who take more than one reformed content course improve their science content knowledge and efficacy towards teaching science significantly more than students who take fewer courses.  相似文献
