Alternative assessment of high school laboratory skills     

Rodney L. Doran  Joan Boorman  Fred Chan  Nicholas Hejaily 《科学教学研究杂志》1993,30(9):1121-1131

The purpose of this study was to develop and validate instruments that will assess the laboratory skills of students completing high school science courses. In each of the science areas (biology, chemistry, and physics), tests were developed around six laboratory tasks. Each test used a two-part format with a total time of 80 minutes. Students had to plan an investigation, collect and organize appropriate data, and formulate conclusions based on calculations and graphs. A different test was developed for 12th-grade students not enrolled in a science course. This test consisted of a series of stations where students conducted a short activity that was presented to them. Over 1000 students from 32 Ohio schools formed the sample for this study. Data are presented by skill and by task. In addition, analysis for gender and school effects is included.  相似文献   

Effects of varying sucrose reinforcers and amobarbital sodium on positive contrast in rats     

Joan S. Rabin 《Learning & behavior》1975,3(4):290-294

The effect of quantity and quality of reinforcement on performance change following a shift to uniform high reward was studied in four groups of rats. Twenty or 200 licks of a 5% or 20% sucrose solution constituted the four incentive conditions. Two additional subject groups were run in the high (20%–200 licks) and low (5%-20 licks) reward conditions to determine how amobarbital sodium, an emotional depressant, influences incentive shift performance. All six groups received 60 preshift runway trials (6/day), followed by 30 high reward trials. Twenty-four extinction trials contrasted drugged and normal performance relating to high and low reward Postshift positive contrast appeared in all nondrugged groups. An emotional base for positive contrast is considered.  相似文献

Critical intercultural conversations: using activity systems analysis as a tool for educational ethnography     

Sabine Siekmann  Joan Parker Webster 《Ethnography and Education》2019,14(3):377-393

ABSTRACT

This paper explores the tensions that exist between the recognition of the importance of ethnicity and culture for individual and group identities without essentilisation, by reframing conceptualisations of multi- and interculturalism. Drawing from our ongoing ethnography conducted with a research community of Alaska Native PhD candidates involved in participatory action research, we examine how situated and multiple positionalities enacted through participation in Engeström’s concept of an ‘activity system’ can: (a) contribute to the ‘doing’ of ethnography and provide an analytic framework for ethnographic research; and, (b) contribute to understandings of multi- and intercultural education that promote the questioning of hierarchical power structures through dialogue aimed toward equity and social justice.  相似文献   

Training for content teachers of English Language Learners: using experiential learning to improve instruction*     

Leslie L. Bohon  Susan McKelvey  Joan A. Rhodes  Valerie J. Robnolt 《Teacher Development》2017,21(5):609-634

Abstract

Experiential learning theory places experience at the center of learning. Kolb’s four-stage cycle of experiential learning suggests that effective learners must engage fully in each stage of the cycle – feeling, reflection, thinking, and action. This research assesses the alignment of Kolb’s experiential learning cycle with the week-long Summer Institute of Assisting, Collaborating, and Training ESL Secondary Content Teachers (ACT-ESL), the first stage of a professional development model designed to train content teachers of English Language Learners (ELLs). Qualitative and quantitative data analysis from pre- and post-surveys determined positive changes in participants’ understanding of key ELL concepts, knowledge, and understanding of instructional strategies and practices. Analysis indicated that the Summer Institute had a large effect (d > 2.00 for each scale), regardless of previous training in ELL instructional strategies. Findings show that the Summer Institute incorporated the cycle of learning and tenets of Kolb’s experiential learning theory and evidenced teacher learning.  相似文献   

The effects of prior information upon perceptions of exceptional children     

Stephen P. Safran  Joan S. Safran  Michael D. Orlansky 《Contemporary educational psychology》1982,7(4):384-394

Students in a university special education course were shown three identical videotapes of children in a school setting. The subjects were randomly divided into three groups, each receiving different written background information (“positive,” “neutral,” or “negative”) prior to viewing the videotapes. It was found that the variations in written information had significant effects upon the subjects' perceptions of the children's behavior, and upon the degree to which the children were regarded as able to function successfully in a regular classroom. These findings suggest that attitudes toward exceptional children are influenced by the way in which prior information, such as that contained in a child's educational records, is presented. Teacher and peer acceptance of exceptional children can be increased if information is presented in a realistic and positive manner.  相似文献

For social justice and inclusion: engaging with the other     

Joan Forbes 《Journal of Research in Special Educational Needs》2006,6(2):99-107

This paper opens with a discussion of the relevance of service integration to the successful implementation of the Integrated Community Schools (ICS) policy in Scotland. It continues to offer an overview of the teacher/speech and language therapist (SLT) collaboration policy context and introduces some of the relevant wider children's services integration policy themes. The approach and aim of a discourse-based analysis are then discussed and the paper continues to suggest how such an approach may be used to uncover individuals' identifications and subject positions. The analytical framework of five dimensions of power is introduced, empirical data are analysed to demonstrate how collaboration operates in practice in one specific collaboration relationship, and the issues of power which were uncovered are examined. The analysis would suggest that while policy discourses construct collaboration in particular ways, practitioners differentially appropriate collaboration and other professional discourses as resources with which to construct acceptable identities.  相似文献   

THE EARLY DEVELOPMENT AND EDUCATION OF HIGHLY ABLE YOUNG CHILDREN     

Joan Freeman 《High Ability Studies》1991,1(2):165-171

Because the very early development of abilities is vitally affected by personal relationships, research emphasis has shifted away from the quasi‐experimental situation to the more natural home context. This has resulted in the rejection of some limiting ideas of very early potential, and particulary appropriate for the highly able, concern with young children's own awareness of what they do. The educational conclusions are that infants who develop and learn with speed and ease need a wide variety of activities, with parents who are aware and responsive, especially in play and verbal interaction. They also need both the appropriate material provision and facilities for practice to develop specific skills.  相似文献   

Conflict and Its Resolution in Preschoolers with and without Disabilities     

Joan Lieber 《Early education and development》1994,5(1):5-17

The sources of conflict, its resolution, and additional conflict components were described for 16 preschoolers with mild disabilities. Conflict episodes were contrasted to those of a comparison group of 15 preschoolers without disabilities. Children were videotaped for two 15-minute freeplay sessions, which were categorized and analyzed using a procedure developed by Laursen and Hartup (1989). Results indicated that children with and without disabilities engaged in conflict on a relatively infrequent basis, and that it was of short duration. In general, there were few differences between the sources of conflict and how they were resolved for children with and without disabilities. There was a tendency, however, for children with disabilities to have more disputes over objects, and for children without disabilities to have more disputes over pretend play. Children resolved their conflicts largely through insistence, and in the majority of conflicts there was a clear winner and loser. Implications for intervention and future research are discussed.  相似文献
