Computer Technology,Science Education,and Students with Learning Disabilities     

Kumar  David  Wilson  Cynthia L. 《Journal of Science Education and Technology》1997,6(2):155-160

The ways computer technology could be used to teach science to students with learning disabilities (LD) are explored. Science is for all students and that includes students with LD. Learning science has both cognitive and affective implications for students with LD. In this context, computer technology provides cognitively engaging and motivating instructional tools for individualizing the mode of delivery; developing expert tutors; anchoring instruction; integrating science with other subjects; reducing cognitive load on working memory; and motivating students to stay on task. These applications are discussed with implications for teaching science to students with LD.  相似文献   

Generating multiple solutions for a problem: A comparison of the responses of U.S. and Japanese students     

Edward A. Silver  Shukkwan S. Leung  Jinfa Cai 《Educational Studies in Mathematics》1995,28(1):35-54

A task involving simple mathematics, yet complex in its call for the generation of multiple solution methods, was administered to about 150 U.S. students, most of whom were in fourth grade. Written responses were examined for correctness, evidence of strategy use and mode of explanation. Results for the U.S. sample were also compared to those obtained from about 200 Japanese fourth-grade students. Students in both countries (a) produced multiple solutions and explanations of their solutions, (b) exhibited almost identical patterns and frequency of strategy use across response occasions, and (c) used the same kinds of explanations, with a majority of the responses involving solution explanations that combined both visual and verbal/symbolic features. Nevertheless, Japanese students tended to produce explanations involving more sophisticated mathematical ideas (multiplication rather than addition) and formalisms (mathematical expressions rather than verbal explanations) than did U.S. students.  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   

How is radial arm maze behavior in rats related to locomotor search tactics?     

Cynthia M. Hoffman  William Timberlake  Joseph Leffel  Rory Gont 《Learning & behavior》1999,27(4):426-444

Norway rats have been shown to depend on short-term spatial memory to find food on a radial arm maze (RAM), but what locomotor search tactics are involved in using this memory effectively? Four experiments distinguished tactics of distance minimizing, central-place search, trail following, thigmotactic search, and random search by using different configurations of a RAM placed flat on the floor of an arena. These search tactics make similar predictions on an elevated RAM but predict different outcomes on a floor RAM because the rats are free to approach the food from any direction. After initial trials dominated by exploration, rats traveled along arms to food, even when the resultant distance was up to three times the minimum distance. With no food present, rats also traveled along arms; with no arms up to present, they traveled along walls to food. It appears that both maze arms and arena walls engage mechanisms related to trail following in rats.  相似文献   

Attachment and Adolescent Psychosocial Functioning   总被引：9，自引：1，他引：8  

Joseph P. Allen  Cynthia Moore  Gabriel Kuperminc  Kathy Bell 《Child development》1998,69(5):1406-1419

To explore the meaning and function of attachment organization during adolescence, its relation to multiple domains of psychosocial functioning was examined in a sample of 131 moderately at-risk adolescents. Attachment organization was assessed using the Adult Attachment Interview; multiple measures of functioning were obtained from parents, adolescents, and their peers. Security displayed in adolescents' organization of discourse about attachment experiences was related to competence with peers (as reported by peers), lower levels of internalizing behaviors (as reported by adolescents), and lower levels of deviant behavior (as reported by peers and by mothers). Preoccupation with attachment experiences, seen in angry or diffuse and unfocused discussion of attachment experiences, was linked to higher levels of both internalizing and deviant behaviors. These relations generally remained even when other attachment-related constructs that had been previously related to adolescent functioning were covaried in analyses. Results are interpreted as suggesting an important role for attachment organization in a wide array of aspects of adolescent psychosocial development.  相似文献   

Creativity Is About Being Free ...     

Cynthia A. Mitchell 《European Journal of Engineering Education》1998,23(1):23-34

I began this journey with the notion that creativity is somehow linked to having the freedom to explore and discover and dissemble and reassemble in whatever form we choose. This notion is compared with the ideas of researchers in the field of creativity. As an engineer who believes in a holistic approach, I am most comfortable with the idea of creativity as a multifarious beast, influenced by both personality and the cultural, social and professional environment in which engineers, in this case, find themselves. This being the case, engineering educators therefore have some opportunity to influence these factors, and hence the development of creative thinking in our students. I then examine a case study of a design project in second‐year chemical and environmental engineering in an attempt to ground these ideas about creativity in engineering education practice, and present the lessons learned from this experience.  相似文献   

Effect of Twinning on Chinese and English Vocabulary Knowledge     

Simpson W.L. Wong  Him Cheung  Mo Zheng  Xiujie Yang  Catherine McBride  Connie Suk-Han Ho  Judy Sze-Man Leung  Bonnie Wing-Yin Chow  Mary Miu Yee Waye 《Child development》2020,91(6):1886-1897

Vocabulary knowledge was tested in a native (Cantonese-Chinese) and foreign (English) language in 150 twins and 150 singletons aged 6–11 years, matched on age, gender, grade level, nonverbal intelligence, parents’ education, family income, and number of siblings and household members. The singletons clearly outperformed the twins on the native vocabulary, but this “twinning effect” was much less noticeable for the foreign vocabulary. The effect on English vocabulary was further reduced after exposure to English at home was controlled. Given that these participants learned most of their English in school rather than home, the present findings support the notion that the twinning effect is associated with increased competition for family interaction in twins compared with singletons.  相似文献   

Multiple perceptions of children's aggression: Differences across neighborhood,age, gender,and perceiver     

Cynthia Hudley  William D. Wakefield  Brenda Britsch  Su‐Je Cho  Tara Smith  Marlene Demorat 《Psychology in the schools》2001,38(1):43-56

We investigated how overtly aggressive behavior was differentially perceived by two types of perceivers, teachers and peers, as a function of student neighborhood, gender, and grade level. Participants (N= 765) were predominantly African American students in grades 3‐5 recruited from two urban public schools in southern California. The neighborhoods surrounding the two schools differed in levels of identified violent crime and economic levels. Teachers in the community experiencing more violence perceived student behavior to be relatively less aggressive and more similar across genders than did teachers in the less violent community. Peers in the community experiencing more violent crime perceived both boys and girls to be somewhat aggressive, whereas in the less violent community, boys were perceived as aggressive more so than were girls. In general, agreement between teacher and peer perceptions was stronger for boys than for girls. © 2001 John Wiley & Sons, Inc.  相似文献   

Setting theoretical and empirical foundations for assessing scientific inquiry and discovery in educational programs     

Paul Zachos  Thomas L. Hick  William E.J. Doane  Cynthia Sargent 《科学教学研究杂志》2000,37(9):938-962

This study was designed to develop measures of student competence in conducting scientific inquiry. Two assessment techniques were developed. The first measures Scientific Inquiry Capabilities, variables which are indicators of diverse aspects of competence in conducting scientific inquiry. The second measures Scientific Discovery, an indicator of success in attaining scientific concepts as a result of direct investigations into natural phenomena. Thirty‐two high school students were presented with tasks requiring the building and testing of logical–mathematical models of natural phenomena. The relationship between each Scientific Inquiry Capability and success in making discoveries was tested. Several Inquiry Capabilities were identified as strongly correlated with success in Discovery, notably: Proportional Reasoning, the Coordination of Theory with Evidence, and the Disposition to Search for Necessary Underlying Principles. © 2000 John Wiley & Sons, Inc.

Culture wars in the classroom: Prospective teachers question science     

Karen Sullenger  Steve Turner  Hart Caplan  Joe Crummey  Rick Cuming  Cynthia Charron  Beth Corey 《科学教学研究杂志》2000,37(9):895-915

Does studying about the nature(s) of science contribute to a prospective teachers' effectiveness as a science teacher? This research grew out of a course created by a science educator and historian of science who believed prospective teachers needed more complex understandings of the cultural wars surrounding science. The research team consisted of five prospective teachers who participated in the course as well as the two instructors. This paper describes the experience of participating in the course from both perspectives. We argue that studying the cultural wars over science contributes to prospective teachers' professional growth as much because the course elicits tacit beliefs about school science as it introduces more complex understandings of science. We found that prospective teachers' tacit beliefs about school science were their greatest barrier to developing more complex understandings about the nature(s) of science. We contend that willingness to grapple with complexity and developing a professional identity by locating oneself in the conversations about the nature(s) of science are better criteria for determining the professional growth of prospective teachers than knowledge measures. Finally, we argue that prospective teachers should be viewed as professionals who are responsible for finding their own voice, making their own decisions, and considering the consequences of their beliefs on their practice. This study raises questions critical to teacher education programs for prospective teachers and teacher‐educators alike. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 895–915, 2000  相似文献
