The role of reinforcement and nonreinforcement in an operant frustration effect     

Larry F. Hughes  Lawrence Dachowski 《Learning & behavior》1973,1(1):68-72

Male albino rats were run in a discrete-trial two-bar operant analog of the double alley. Completion of a FR 4 response chain on the first bar was rewarded 50% of the time for the 12 experimental Ss, but was never rewarded for the 12 control Ss. Both groups received consistent reward at the end of a FR 4 chain on the second bar. Eighty-four trials were given at a rate of four trials per day. A significantly faster rate of responding on the second bar was found following nonrewarded first-bar ratios than following rewarded first-bar ratios. This frustration effect was not attributable to response depression, since the nonrewarded performance of the experimental group exceeded that of the control group.  相似文献

TAKING ACCOUNT OF STUDENTS’ EMPLOYMENT EXPERIENCE IN A COURSE OF INITIAL TEACHER EDUCATION     

Christopher Turner  Michael Williams 《Assessment & Evaluation in Higher Education》1992,17(2):101-110

This study focuses on an industrial, commercial and community experience programme within a full time, one year postgraduate teacher training course. Acknowledging the heterogeneous experiences brought to this course by the students, an attempt was made to detect links between the students’ prior experience and their experience of the industrial, commercial and community programme. The students completed questionnaires before and after a placement and the findings are described. These findings contribute to an evaluation of the programme and suggest a number of important questions for those responsible for designing teacher education courses.  相似文献   

Connectedness among taiwanese middle school students: a validation study of the hemingway measure of adolescent connectedness     

Michael?J.?KarcherEmail author  Yun?Lee 《Asia Pacific Education Review》2002,3(1):92-114

Theories of adolescent connectedness suggest that adolescents strive to become connected by engaging with and valuing the people, activities, and worlds in their social ecology. The purpose of this study was to examine the psychometric properties of a measure designed to assess these worlds of connectedness among 320 junior high school students in Taiwan. The subscales and composite scales evidenced satisfactory reliability and concurrent validity. A hypothesized three-factor, higher order structural model of connectedness was cross-validated. Girls were generally more connected than boys. Both connectedness to school and to friends explained more variance in connectedness to self than did family connectedness. There was mixed support for separation-individuation processes. The measure appears promising in terms of future research on adolescent social development in the Asia Pacific.  相似文献   

Parameters in television captioning for deaf and hard-of-hearing adults: effects of caption rate versus text reduction on comprehension     

Burnham D  Leigh G  Noble W  Jones C  Tyler M  Grebennikov L  Varley A 《Journal of deaf studies and deaf education》2008,13(3):391-404

Caption rate and text reduction are factors that appear to affect the comprehension of captions by people who are deaf or hard of hearing. These 2 factors are confounded in everyday captioning; rate (in words per minute) is slowed by text reduction. In this study, caption rate and text reduction were manipulated independently in 2 experiments to assess any differential effects and possible benefits for comprehension by deaf and hard-of-hearing adults. Volunteers for the study included adults with a range of reading levels, self-reported hearing status, and different communication and language preferences. Results indicate that caption rate (at 130, 180, 230 words per minute) and text reduction (at 84%, 92%, and 100% original text) have different effects for different adult users, depending on hearing status, age, and reading level. In particular, reading level emerges as a dominant factor: more proficient readers show better comprehension than poor readers and are better able to benefit from caption rate and, to some extent, text reduction modifications.  相似文献

Balancing varied assessment functions to attain systemic validity: Three is the magic number     

Daniel T. Hickey  Steven J. Zuiker  Gita Taasoobshirazi  Nancy Jo Schafer  Marina A. Michael 《Studies in Educational Evaluation》2006,32(3):180

Accountability-oriented reforms demand immediate and continual gains on achievement test, for all students, and without diminishing other outcomes or undermining instruction. This paper describes a framework for aligning classroom assessment and external testing with the aim of negotiating these seemingly contradictory goals. The framework varies the sensitivity to instruction and the representations of knowledge across approaches to assessment. Cycles of design- based studies successively refine relationships between a curriculum and the frame that each assessment provides. Doing so, we argue, leverages the unique formative and summative balance across assessments in order to scaffold learning and demonstrate the “consequential” validity of our strategy without compromising curricula, instruction, or the “evidential” validity that warrants their continued use.  相似文献   

Early Identification and Intervention: Head Start's Response to Mental Health Challenges     

Michael L. Lopez  Louisa B. Tarullo  Steven R. Forness  Cheryl A. Boyce 《Early education and development》2000,11(3):265-282

Serving low-income children from birth to age five and their families, Head Start is a primary venue for identification and intervention in the area of child mental health. However, recent research has demonstrated that the knowledge base regarding prevalence, developmental course, and predictive power of child mental health problems is lacking for young children in general and low-income, diverse populations in particular. Head Start's agency-level data is often discrepant from both national estimates and small, intensive studies of similar populations, perhaps for reasons related to availability of community services and professional staff, as well as concerns about stigmatization. Following on recent expert recommendations, new collaborative Federal initiatives are underway to increase our understanding of the types, trajectories, and treatments of mental health problems affecting the vulnerable children served by Head Start. The paper concludes with a call to action for the field in the area of young children's mental health.  相似文献
