Constructing explanations is an essential skill for all science learners. The goal of this project was to model the key components of expert explanation of molecular and cellular mechanisms. As such, we asked: What is an appropriate model of the components of explanation used by biology experts to explain molecular and cellular mechanisms? Do explanations made by experts from different biology subdisciplines at a university support the validity of this model? Guided by the modeling framework of R. S. Justi and J. K. Gilbert, the validity of an initial model was tested by asking seven biologists to explain a molecular mechanism of their choice. Data were collected from interviews, artifacts, and drawings, and then subjected to thematic analysis. We found that biologists explained the specific activities and organization of entities of the mechanism. In addition, they contextualized explanations according to their biological and social significance; integrated explanations with methods, instruments, and measurements; and used analogies and narrated stories. The derived methods, analogies, context, and how themes informed the development of our final MACH model of mechanistic explanations. Future research will test the potential of the MACH model as a guiding framework for instruction to enhance the quality of student explanations. 相似文献

Early childhood teacher educators frequently enhance their teaching by reading children’s books to their adult students. It
is not unusual for faculty outside of early childhood to question devoting precious class time to read-alouds which they may
consider a curious, if not frivolous, instructional strategy. Quality children’s literature can, however, enhance students’
experiences in the college classroom, contribute to their understanding of course content, promote their personal growth and
self-understanding, increase their appreciation for quality children’s literature, and enhance their ability to integrate
storybooks into their own teaching. Children’s books often capture a child’s point of view. They have the potential to provide
historical or cultural perspectives on children and families. They also can lead to the examination of universal truths and
can facilitate the discussion of sensitive or emotional issues A list of books with suggested uses is included. 相似文献

Why Talk about Mental States? The Significance of Children's Conversations with Friends, Siblings, and Mothers 总被引:5,自引:1,他引:5
Natural language data from 38 47-month-olds recorded at home in unstructured observations were analyzed and comparisons made of characteristics of mental state term use in child-friend, child-sibling, and child-mother dyads. Significantly more references to mental states were made by the children in conversations with siblings and friends than with mothers. Frequent use of mental state terms by both partners was related to cooperative interaction in both child-friend and child-sibling dyads and several associations were found with measures of language fluency, gender, and maternal education, although these varied across the 2 dyads. Children's use of mental state terms in conversations with siblings and friends was correlated with their performance on two false belief measures. Results highlight the importance of extending investigations into the social implications of the development of children's "theories of mind." 相似文献

This study investigated the validity of the Roberts Apperception Test for Children (RATC) with an elementary school sample by examining the appropriateness of the standardization norms with other nonclinical samples. A sample of 86 children, ages 8–11 years, completed the RATC. Analyses revealed that the current sample of nonclinical children differed significantly from the standardization sample on six of the eight Adaptive Scales and three of the five Clinical Scales. Findings suggest that the children in this study form a separate and distinct group from the well‐adjusted children upon which the RATC scales were normed and supports previous research that suggests the standardization of the RATC is inadequate. The current findings strongly suggest that the norms for the RATC not be used for clinical diagnosis until restandardization is completed. © 1999 John Wiley & Sons, Inc. 相似文献

The present qualitative study examined the experiences of nine students with mild disabilities during their first year in an inclusive middle school in a Midwestern state of the United States (US). Data were gathered through interviews with students, teachers, and parents; classroom observations; and document analysis. Following the data analysis, three themes were identified: how the demands of navigating a new environment increased students’ anxiety; how students satisfied their need for belonging; and how students’ perceptions of school influenced their attitude towards help. Suggestions for facilitating school transitions for early adolescents with mild disabilities are provided. 相似文献

For adults with low literacy skills, the role of phonology in reading has been fairly well researched, but less is known about the role of morphology in reading. We investigated the contribution of morphological awareness to word reading and reading comprehension and found that for adults with low literacy skills and skilled readers, morphological awareness explained unique variance in word reading and reading comprehension. In addition, we investigated the effects of orthographic and phonological opacity in morphological processing. Results indicated that adults with low literacy skills were more impaired than skilled readers on items containing phonological changes but were spared on items involving orthographic changes. These results are consistent with previous findings of adults with low literacy skills reliance on orthographic codes. Educational implications are discussed. 相似文献

This paper explores the implications of the effective integration of research, teaching and learning for academic development through the lens of an international multi‐institutional comparison of student perceptions of research and its impact on their learning environment. The study, with a sample of over 500 final‐year undergraduate students across three institutions in the UK and Canada, represents a spectrum of research and teaching intensive universities and is one of the largest exploring undergraduate student perceptions of research in the linking teaching and research literature. The results indicate a complex relationship between student perceptions and experiences of research and the type of institution, as well as the individual, institutional and national context. They also inform the discussion of particular issues that academic developers face and the strategies they use to improve the integration of research and teaching to benefit the undergraduate learning experience in their institution. Cet article explore les implications, pour le développement pédagogique, de l’intégration effective de la recherche, de l’enseignement et de l’apprentissage à l’aide de la lentille d’une comparaison internationale multi institutionnelle des perceptions étudiantes à l’égard de la recherche et de leur impact sur l’environnement d’apprentissage. L’étude, reposant sur un échantillon de plus de 500 étudiants en dernière année de 1er cycle, provenant de trois institutions au Royaume‐Uni et au Canada, représente un spectre d’universités centrées sur l’enseignement ou sur la recherche. L’étude constitue une des recherches les plus importantes au sujet des perceptions étudiantes à l’égard de la recherche dans la littérature portant sur le lien entre l’enseignement et la recherche. Les résultats indiquent une relation complexe entre les perceptions et les expériences des étudiants, et le type d’institution, de même qu’avec les contextes individuel, institutionnel et national. Les résultats contribuent aussi à la discussion de questions particulières auxquelles les conseillers pédagogiques font face ainsi que les stratégies que ceux‐ci utilisent en vue d’améliorer l’intégration de la recherche et de l’enseignement de façon à en faire bénéficier l’expérience d’apprentissage au 1er cycle au sein de leur institution. 相似文献

RESEARCH FINDINGS: The purpose of this study was to examine the relations of children's effortful control and quality of relationships with teachers to school attitudes longitudinally in an ethnically diverse and economically disadvantaged sample. Data were collected as part of a larger intervention project during mid-fall, winter, and late spring (ns = 823, 722, and 758, respectively) for 2 cohorts of 3- to 5-year-olds (collected during 2 different school years). Children's effortful control was assessed in the fall with parents' and teachers' reports and 2 behavioral measures. Teacher-child relationship quality was assessed mid-year with teachers' reports of closeness and conflict. Attitudes toward school were assessed in late spring using teachers' and students' reports of school avoidance and liking. Effortful control, in general, was positively correlated with teacher-child closeness and school liking and negatively correlated with conflict and school avoidance. Using structural equation modeling and controlling for sex and ethnicity, we found that effortful control was positively related to teacher-child relationship quality, which in turn was positively related to school attitudes. Furthermore, the relation of effortful control to school attitudes was mediated by teacher-child relationship quality. PRACTICE OR POLICY: Results provide evidence for the importance of relational processes that take place within the classroom context and have implications for teachers and clinicians working to increase school success in ethnic minority and low-income children. 相似文献

Using a life history approach, this article explores the ways in which women in the military who are also mothers learn to embody various masculinities and femininities as they negotiate workplace gender processes. Complex intersections of gendered communities of practice result in the participants’ learning to variously understand, accept, shape and/or resist interlinked personal, professional and organizational gendered discourses. First, I discuss theories of learning in communities of masculinity and femininity practice, exploring how they connect to the military context. Second, I explain how life history methodology enables an examination of participant learning through personal, organizational and societal constructs. Third, I detail the findings as they relate to the complex ways in which women in the military learn to embody various masculinities and femininities as they negotiate workplace gender processes. Last, I conclude that participants transgressed and reinforced certain boundaries between various military communities of masculinity and femininity. 相似文献
