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   

Primary pre-service teachers' pedagogical reasoning skills     

Mr. Ray Peterson  Associate Professor David Treagust 《Research in Science Education》1992,22(1):323-330

This paper discusses a preliminary investigation into primary pre-service teachers' pedagogical reasoning skills. Results from this investigation led to the development of a problem-based learning model which focused on improving primary pre-service teachers' pedagogical reasoning skills. The problem-based learning model uses pedagogical reasoning as the basis for creating problem situations for the pre-service teachers to investigate. The paper reports on pre-service teachers' views on the use of the approach to improve their pedagogical reasoning skills.

Letter names, letter sounds and phonological awareness: an examination of kindergarten children across letters and of letters across children     

Mary Ann Evans  Michelle Bell  Deborah Shaw  Shelley Moretti  Jodi Page 《Reading and writing》2006,19(9):959-989

In this study 149 kindergarten children were assessed for knowledge of letter names and letter sounds, phonological awareness, and cognitive abilities. Through this it examined child and letter characteristics influencing the acquisition of alphabetic knowledge in a naturalistic context, the relationship between letter-sound knowledge and letter-name knowledge, and the prediction of Grade 1 phonological awareness and word identification from these variables. Knowledge of letter sounds was better for vowels and for letters with consonant–vowel names than for those with vowel–consonant names or names bearing little relationship to their sounds. However, there were anomalies within each category reflecting characteristics of the individual letters. Structural equation modelling showed that cognitive ability, comprising receptive vocabulary, non-verbal reasoning, rapid automatized naming of colours, and phonological memory significantly contributed to alphabetic knowledge and phonological awareness. In turn, letter-name knowledge but not phonological awareness predicted letter-sound knowledge and subsequent reading skill.This research was supported by a grant from the Social Sciences and Humanities Research Council of Canada to the first author. Thank you is extended to the participating schools and children and to Ian Newby-Clark for his orientation to AMOS.

Presenting Complex Teacher Evaluation Data: Advantages of Dossier Organization Techniques Over Portfolios     

Kenneth D. Peterson  Dannelle Stevens  Carol Mack 《Journal of Personnel Evaluation in Education》2001,15(2):121-133

The development of extensive and authentic teacher evaluation raises questions about how best to organize and present the increased amount and variety of assessment materials. Portfolios have been suggested for teacher evaluation because they are well suited to capture the complexities of teaching. However, portfolios 1) are difficult to judge, 2) are difficult to archive, 3) lack key information, 4) miss excellent teachers with simple materials, 5) rarely plan for audiences, 6) distort when required, and 7) bring conflicts of interest. Teacher dossiers are compressed collections of objective data which are easier to judge, demonstrably reliable, and cost-effective.  相似文献   

Elephants Dancing in My Head: A Developmental Approach to Children''s Concepts of Specific Pains     

Cynthia Harbeck  Lizette Peterson 《Child development》1992,63(1):138-149

The present study produced an empirically derived, developmental continuum of children's understanding of specific pains. Subjects of 5 age groups: preschool (ages 3-4), first grade (ages 6-7), third grade (ages 8-10), sixth grade (ages 11-12) and college freshmen (ages 18-23) were interviewed with open-ended questions. The subjects were questioned extensively about 3 specific types of pain: an injury (skinned knee), a medical intervention (injection), and an illness (headache). Subjects were asked to describe each pain, tell why the pain hurt, and state the value of the pain. Their answers were then categorized and the categories ordered developmentally by experts in pediatric pain who were unaware of the children's ages. Then children's specific answers were given developmental scores. Multivariate analyses revealed that older children had more complex and precise understandings of pain, and this pattern differed by type of pain and by aspect of pain being considered. The subjects were also asked to report the frequency of their own pains and their parents' pain; parental and self-reported pains were closely related.  相似文献   

Positive justice reasoning in deaf and hearing children before and after exposure to cognitive conflict     

C C Peterson  J L Peterson 《American annals of the deaf》1989,134(4):277-282

The development of positive justice reasoning in profoundly deaf, signing Australian 7- to 12-year-olds and hearing children was compared. Reactions to cognitive conflict were also assessed. The performance of those deaf children whose signed English skills were adequate to give detailed justifications for reward allocation was examined separately. The deaf children were delayed relative to hearing children in number and liquid conservation, but equally mature in justice reasoning. Spontaneous conflicts with signing peers over sharing possessions conceivably could be responsible for the fluently signing deaf children's development of positive justice reasoning on pace with their normally-hearing counterparts. Experimentally-induced conflict resulted in progress for the hearing but not the deaf children. Results are discussed in relation to factors that promote deaf children's tolerance for ambiguity (Brice, 1985) and impede their resolution of cognitive conflict (Liben, 1978).  相似文献
