Thinking about technology: Applying a cognitive lens to technical change     

Sarah Kaplan  Mary Tripsas 《Research Policy》2008,37(5):790-805

We apply a cognitive lens to understanding technology trajectories across the life cycle by developing a co-evolutionary model of technological frames and technology. Applying that model to each stage of the technology life cycle, we identify conditions under which a cognitive lens might change the expected technological outcome predicted by purely economic or organizational models. We also show that interactions of producers, users and institutions shape the development of collective frames around the meaning of new technologies. We thus deepen our understanding of sources of variation in the era of ferment, conditions under which a dominant design may be achieved, the underlying architecture of the era of incremental change and the dynamics associated with discontinuities.  相似文献   

Rethinking science literacy: Enhancing communication and participation in school science through affirmational dialogue journal writing     

Mary Hanrahan 《科学教学研究杂志》1999,36(6):699-717

For many students the study of science can be very disaffirming. This may lead to passivity in class and a lifelong disaffection with science, outcomes which defeat the long‐term purpose of trying to achieve scientific literacy for all students. This article represents a new way of framing scientific literacy with a “science for all” goal, based on a nexus of psychological, sociological, and critical literacy theory. A science education researcher and a science teacher collaborated in trialing the use of affirmational dialogue journal writing with early adolescents in a high school situated in a low socioeconomic status area. The intervention was found to be successful on a number of fronts. An approach which affirms students' experience can lead to a deeper approach to learning for adolescent science students. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 699–717, 1999  相似文献

Mastery and exercise play interventions: motor skill development and verbal recall of children with and without disabilities     

Nadia Cristina Valentini  Licia Pierosan  Mary E. Rudisill  Peter A. Hastie 《Physical Education & Sport Pedagogy》2017,22(4):349-363

Background: Fundamental motor skill proficiency is essential for engagement in sports and physical play and in the development of a healthy lifestyle. Children with motor delays (with and without disabilities) lack the motor skills necessary to participate in games and physical activity, and tend to spend more time as onlookers than do their peers. As such, intervention programs are crucial in promoting motor skill development of children with motor delays. While mastery climate (MC) interventions have shown to positively impact children’s motor performance, what is unknown is the impact of cognitive strategies used by children within these climates. Furthermore, although vigorous play seems to be related to the development of gross motor skills, it is still unknown if children with and without disabilities would benefit from exercise play (EP) interventions.

Purpose: This study examined the effects of MC and EP interventions on the motor skill development and verbal recall (VR) of children with motor delays. The sample included children with and without disabilities.

Research designs: One hundred and thirty-eight children from 27 urban public schools were referred to the present study. Children were assessed using the Test of Gross Motor Development second edition (TGMD-2) and a VR checklist. Sixty-four children (18 with disabilities and 46 without) met the inclusion criteria, which was a score less than the fifth percentile on the TGMD-2. Participants were randomly assigned to the MC or EP 14-week interventions emphasizing gross motor skill practice.

Data collection and analysis: Children were assessed at pre- and post-intervention. A 2 (groups)?×?2 (disability) × 2 (time) analyses of variance with repeated measures on the last factor was conducted. Change scores, t-test comparisons on the delta scores and Cohen’s D were also calculated.

Results: The MC group demonstrated significant and positive changes over the intervention period. Further, the MC group showed superior locomotor and object control performance and higher recall of verbal cues (p?≤?.05) at post-intervention compared to the EP group. Children with and without disabilities within the MC showed similar patterns of improvement. The EP intervention did not demonstrate significant improvements.

Conclusion: Children with and without disabilities showed improvements in motor skills and VR when exposed to an MC, incorporating the six TARGET structures. These structures included (a) providing feedback and encouragement, providing opportunities for decision-making and establishing personal goals, (b) including parents in the recognition of children’s achievements, (c) creating opportunities to experience leadership and self-pacing, (d) guiding children to use verbal cues and modeling when practicing gross motor skills, and (e) providing demonstrations and teaching children to self-monitor their performance. Instruction is therefore seen as critical to learning gross motor skills, as demonstrated from the findings. Although there were opportunities for vigorous play within the EP intervention, the children did not show improvements in motor performance or VR. These findings suggest that new trends in teacher education physical education to prioritize physical activity over good motor skill instruction may not be advantageous for children in the early years, and should be reconsidered.  相似文献   

Physical Education Students’ Ownership,Empowerment, and Satisfaction With PE and Physical Activity     

E. Whitney G. Moore  Mary D. Fry 《Research quarterly for exercise and sport》2017,88(4):468-478

Individuals experiencing a highly caring, task-involving, and low ego-involving exercise climate have reported greater ownership in exercise class and empowerment to exercise in general. Purpose: This study examined the relationship between ownership and empowerment in exercise, with 2 context-specific outcomes, satisfaction with physical education (PE) and physical activity, respectively. Given the mission of PE to foster individuals’ lifelong physical activity habit, the perceptions of high school students were collected for this study. Ownership in exercise was hypothesized to be significantly, positively correlated with students reporting satisfaction in PE more than their satisfaction in physical activity, whereas empowerment in exercise was hypothesized to be more strongly, positively correlated with students’ physical activity satisfaction. A second purpose of this study was to test the measurement quality of the updated Empowerment in Exercise Scale (EES; now 13 items). Method: High school students (N = 502, 43% female) in a Midwestern U.S. school district completed a survey. Results: Confirmatory factor analysis supported the internal measurement structure of the EES (λ = .62–.91; McDonald’s omega = .89) across student gender (strong invariance). Additionally, the structural equation modeling analysis revealed only 1 parameter moderated by the students’ gender (latent mean of ownership). The hypotheses were supported, such that ownership in exercise was more strongly correlated with PE satisfaction (r = .87) and empowerment in exercise had a stronger correlation with physical activity satisfaction (r = .92). Conclusion: These results support the beneficial effect a satisfying experience in PE can have on students’ satisfaction with physical activity outside of school.  相似文献   

Improving Support Service Decision-Making: Consumer feedback regarding updates to VISTA     

Michael F. Giangreco  Susan W. Edelman  Catherine Nelson  Mary Rose Young  Richard Kiefer-O'Donnell 《International Journal of Disability, Development & Education》1999,46(4):463-473

This study provides data from 73 educational team members who used an updated version of the Vermont Interdependent Services Team Approach (VISTA) to assist them in planning educationally necessary support services for 11 students with multiple disabilities in general education classes. These data provide evaluative consumer feedback about changes in VISTA based on limitations identified through previous research. The results indicated that the changes were perceived positively by consumers, particularly related to overall quality, practicality, and more substantive involvement of parents and general education teachers in support service decision-making. Study respondents also identified areas in need of continued improvement in VISTA. Implications for future research, development, and practice are discussed.  相似文献   

Developing a Preschool Play-based Curriculum     

Mary Frances Hanline 《International Journal of Disability, Development & Education》1999,46(3):289-305

The importance of play on a young child's development cannot be understated. Play gives children opportunities to understand the world, interact with others, express and control emotions, develop symbolic capabilities, attempt novel or challenging tasks, solve problems, and practice skills. Play may contribute to the development of posture, movement, and self-sufficiency. There also appears to be a positive relationships between the frequency and complexity of young children's play and IQ, problem-solving, creativity, language and literacy, and social competence. This paper provides a review of the literature and describes the development of a preschool play-based curriculum for children with disabilities.  相似文献   

The Influence of Children's Literature on Gender Role Perceptions: A Reexamination     

Mary L. Trepanier-Street  Jane A. Romatowski 《Early Childhood Education Journal》1999,26(3):155-159

This project reexamined young children's gender attitudes regarding occupational roles. The results of this study suggested that young children's atitudes, while still generally stereotypic, were more flexible regarding occupational roles. The reading of carefully selected books and book related activities positively influenced gender attitudes.  相似文献   

Internships as Commencement: Mathematics and Science Research Experiences as Catalysts for Preservice Teacher Professional Development     

Karen Langford  Mary Ann Huntley 《Journal of Mathematics Teacher Education》1999,2(3):277-299

Among the initiatives of the Maryland Collaborative for Teacher Preparation (MCTP) is a summer research internship program that places preservice middle grades teachers in extended collaboration with professional mathematicians, scientists, and educators engaged in research and curriculum development activities. We describe the MCTP internship program including the rationale for and structural features of the program. We also highlight the effects of the internship experience on preservice teachers' conceptions of and beliefs about the nature and processes of mathematics and science, and the teaching of mathematics and science. Our findings suggest that the internship experience is a fundamentally significant life experience for preservice teachers. Furthermore, internships have the potential for realizing reform in mathematics and science education; that is, preservice teachers who have participated in MCTP internships intend to bring a holistic, conceptually oriented view of mathematics and science to their classrooms. The paper concludes with a summary of ongoing programmatic and logistical challenges of the MCTP internship program. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献
