PRESERVICE MATHEMATICS AND SCIENCE TEACHERS IN AN INTEGRATED TEACHER PREPARATION PROGRAM FOR GRADES 7–12: A 3-YEAR STUDY OF ATTITUDES AND PERCEPTIONS RELATED TO INTEGRATION     

Donna F. Berlin  Arthur L. White 《International Journal of Science and Mathematics Education》2010,8(1):97-115

The purpose of this article is twofold: (a) to describe a unique teacher licensure program for grades 7–12 that integrates mathematics, science, and technology education and (b) to explore the attitudes and perceptions related to the integration of mathematics, science, and technology education of three cohorts of preservice teachers enrolled in the first 3 years of the program. Eighty-one preservice teachers responded to a semantic differential to measure attitudes and perceptions related to “mathematics, science, and technology education integration.” Principal components and internal consistency reliability analyses were computed to provide validity and reliability evidence. Preservice teachers also responded to one open-ended, free-response written question, “What does the integration of mathematics, science, and technology education mean to you?” Multivariate and univariate analyses of variance with repeated measures and Pearson cross-tabulation chi-square analyses were computed to identify pretest–posttest differences for the value and difficulty scales, identified by the principal components analysis. Analytic inductive methods were used to identify emergent themes in student written responses to the open-ended question. Results indicated no change in preservice teacher attitudes and perceptions related to the value of integration—they clearly valued integration at the onset and completion of the program, often citing student benefits. However, a significant change in preservice teacher attitudes and perceptions related to difficulty was noted. Upon completion of the program, preservice teachers perceived integration to be more difficult and identified barriers and challenges—demonstrating a more realistic, practical, and cautious approach to the integration of mathematics, science, and technology education.  相似文献   

Dramatic Interpretations: Performative Responses of Young Children to Picturebook Read-Alouds     

Donna Sayers Adomat 《Children‘s Literature in Education》2010,41(3):207-221

In this qualitative study, the author explores how young readers build literary understanding through performative responses in picturebook read-alouds. Performative responses allow children to create and express meaning in ways that go beyond talk and that engage their creativity and imagination. They include a variety of modalities, such as gesture, mime, vocal intonation, characterization, and dramatization. Certain children show a propensity for responding in individual or characteristic ways. By focusing on the performative responses of one second-grade reader, the author defines the characteristics of performative responses and how children build literary understanding through them. Performative responses helped this young, struggling reader to immerse herself in the story world, create the mood of the story, show an understanding of the unfolding narrative, deepen her understanding of characters, and involve her classmates in a rich, and sometimes raucous, exploration of stories through spontaneous dramatizations. The author argues that performative responses open up an imaginative world to children, allow children to contribute actively to the construction of meaning, give children agency in creating their own curriculum, and allow for a collaborative environment that builds on the strengths of the students in the group.  相似文献   

How do pre-kindergarteners spend their time? Gender,ethnicity, and income as predictors of experiences in pre-kindergarten classrooms   总被引：2，自引：0，他引：2

The current paper considers how children spend their time in state-funded pre-kindergarten programs and how time use relates to ethnicity, gender, and family income, based on the assumption that how time is spent in pre-kindergarten is relevant for the programs’ success in narrowing achievement gaps. Classroom observations of 2061 children in 652 pre-k programs in 11 states were analyzed. Findings indicated that the pre-kindergarten day was roughly equally divided among free choice, teacher-assigned activities, and meals/routines. Children spent much of their time in language/literacy, social studies, and art, and less time in math and gross motor activities. Much of the pre-k day was spent in ‘no coded learning activity.’ Children in classes with lower proportions of Latino and African American children and higher average income-to-need ratios were generally engaged in richer and more stimulating experiences. The child-level variables of ethnicity and income were generally unrelated to how children spent their time, above and beyond the effects of classroom-level ethnicity and income. There were generally small, but significant gender differences – always in the gender-stereotyped direction – in how time was spent, especially during free choice time.  相似文献

Scaling Up the TREC Collection   总被引：3，自引：3，他引：0  

David Hawking  Paul Thistlewaite  Donna Harman 《Information Retrieval》1999,1(1-2):115-137

Due to the popularity of Web search engines, a large proportion of real text retrieval queries are now processed over collections measured in tens or hundreds of gigabytes. A new Very Large test Collection (VLC) has been created to support qualification, measurement and comparison of systems operating at this level and to permit the study of the properties of very large collections. The VLC is an extension of the well-known TREC collection and has been distributed under the same conditions. A simple set of efficiency and effectiveness measures have been defined to encourage comparability of reporting. The 20 gigabyte first-edition of the VLC and a representative 10% sample have been used in a special interest track of the 1997 Text Retrieval Conference (TREC-6). The unaffordable cost of obtaining complete relevance assessments over collections of this scale is avoided by concentrating on early precision and relying on the core TREC collection to support detailed effectiveness studies. Results obtained by TREC-6 VLC track participants are presented here. All groups observed a significant increase in early precision as collection size increased. Explanatory hypotheses are advanced for future empirical testing. A 100 gigabyte second edition VLC (VLC2) has recently been compiled and distributed for use in TREC-7 in 1998.  相似文献   

Doing a science project: Gender differences during childhood     

Lauren B. Adamson  Martha A. Foster  Martha L. Roark  Donna B. Reed 《科学教学研究杂志》1998,35(8):845-857

By adolescence, men's participation and achievement in science exceeds women's. This article reports a case study that examined the beginnings of this gender differentiation during a naturally occurring academic activity that was designed to support and guide young children's interest in doing science. Data were collected during 2 successive years of a science fair for children in Grades 1–6 of a progressive private school. A total of 268 projects were characterized in terms of achievement and area of science. Parents provided information about the way children selected and created projects. In both years and in all grade levels, boys tended to choose to work in the physical sciences, and girls in the biological and social sciences. Peer collaborations were exclusively same sex. Achievement and parental involvement were not gender related. Factors are discussed that might lead to an early divergence of boys' and girls' interests in science within a context that promotes its exploration. © 1998 John Wiley & Sons, Inc.

The prediction of first-grade reading achievement from WPPSI scores of preschool children     

Donna Romano White  Ellen Jacobs 《Psychology in the schools》1979,16(2):189-192

The purpose of this study was to measure the relationship between the WPPSI IQs and subtest scaled scores in preschool children and their reading achievement in grade one. Twenty-eight suburban middle class children were given the WPPSI at ages three to five and retested with the Gray Oral Reading Test near the end of first grade. Significant correlations between WPPSI IQs and reading were found. These correlations were similar in magnitude to those obtained between WPPSI IQs of kindergarten children and grade one reading. Further study of the predictive power of the Geometric Designs and Arithmetic subtests was suggested on the basis of correlations obtained between these subtests and later reading scores.  相似文献
