This case study describes the efforts of librarians to integrate mobile devices, collaboration tools, and resources into a School of Medicine third-year pediatric clerkship. Additional class emphasis is on evidence-based searching and journal article evaluation and presentation. The class objectives ensure that students are comfortable with mobile devices and collaboration tools. Over the eight-year history of the course, student acceptance of the mobile devices used diminished as the devices aged, necessitating the evaluation and selection of new technologies. Collaboration tools and mobile applications employed in the course evolved to accommodate curriculum changes. 相似文献

This study examined the effect of exemplar typicality on reaction time and accuracy of categorization. High-functioning children (age 9-12), adolescents (age 13-16), and adults with autism (age 17-48) and matched controls were tested in a category verification procedure. All groups showed improved processing throughout the lifespan for typical and somewhat typical category exemplars. However, individuals with autism responded more slowly than matched controls to atypical exemplars at all ages. The results are discussed in terms of potential differences in the type of processing that may be required for categorizing typical and atypical category exemplars. Parallels are also drawn to the results of previous studies on face processing in individuals with autism. 相似文献

The extent to which current theories on family-related factors associated with children's depression and conduct problems are applicable to Mexican American children was examined among demographically comparable samples of low-income Mexican American (English and Spanish speaking) and Euro-American mothers and children. There were ethnic differences in mean levels of children's depression, maternal inconsistent discipline, and hostile control. In addition, there were differences across language within the Mexican American sample on levels of reported maternal inconsistent discipline and hostile control. The vast majority of relations between parenting and mental health were similar between Mexican Americans and Euro-Americans, suggesting that current theories do apply across ethnic groups. However, analyses across language within the Mexican American sample showed that language preference moderated the relation between maternal acceptance and children's conduct problems. Moreover, the relation between acceptance and hostile control differed across groups. These results are discussed in light of the relative influence of ethnicity and other contextual variables on parenting and children's mental health. 相似文献

Parental Cultural Socialization of Mexican‐American Adolescents’ Family Obligation Values and Behaviors 下载免费PDF全文

The current study examined how parents’ cultural socialization efforts contribute to adolescents’ family obligation values and behaviors and how these processes may depend upon the relational climate at home. Utilizing survey and daily diary methodologies, 428 Mexican‐American adolescents (50% males; Mage = 15 years) and their parents (83% mothers; Mage = 42 years) participated in the study. Adolescents reported on their family obligation values and engagement in family assistance tasks across 14 days. Parents reported on their cultural socialization practices. Results indicated that parental cultural socialization was associated with adolescents’ family obligation values and behaviors when parent–child relationships were low in conflict and high in support. Findings suggest that the transmission of cultural values and practices is best facilitated through positive parent–child relationships. 相似文献

Can research on science learning and instruction inform standards for science education? 总被引:1,自引:0,他引:1

We contrast the current science education reform effort with the reforms of the 1960s and suggest how the current effort could be enhanced. We identify insights from recent research that we believe can inform the reform process, in particular, to reach all science students and also impart a cohesive view of science. We propose an alternative models view of scientific explanation and show how this view would contribute to reforms of (1) course goals, (2) social aspects of science learning, (3) instructional practices, and (4) roles for technology.This paper summarizes discussions and debates that the authors have had over the last few years. The dialogue stems, in part, from our joint participation in the American Educational Research Association Special Interest Group on Education in Science and Technology (AERA SIG:EST) leadership. This paper communicates the spirit of our thinking and does not necessarily reflect the view of SIG:EST, or any other organization.We gratefully acknowledge the support of National Science Foundation Grant MDR-9253462 in work related to this paper.

Children's number sense in kindergarten was used to predict their calculation fluency in second grade (N = 198). Using block entry regression, usual predictors of age, reading, memory, and verbal and spatial cognition were entered in the first block and number sense measures were added in the second block. Number sense measures contributed a significant amount of variance over and above the more general predictors (26%-42%). Uniquely predictive subareas were active memory for numbers, number knowledge, and number combinations, with number combinations standing out as the strongest single predictor. Number sense screening in kindergarten, using "at-risk" versus "not-at-risk" criteria, successfully ruled out 84% of the children who did not go on to have calculation fluency difficulties and positively identified 52% of the children who later showed fluency difficulties. The relation of early number skills to later calculation fluency has important implications for math screening and intervention. 相似文献

This paper explores challenges encountered in a study of culturally relevant pedagogy that examines numeracy practices of under-served youth in secondary mathematics classrooms and in their peer communities at school. Taking a sociocultural stance toward studying under-served youths’ cultural practices as valuable resources for mathematics learning poses several methodological challenges, including identifying distinct cultural groups; adopting a view of mathematics as a social practice; and examining youth cultural practices to identify what counts as a viable example of practice relevant to mathematics practices and knowledge. Two dimensions of cultural practices are the focus: (1) communication, interaction, and language-use patterns that youth develop as they engage in the cultural practices of their peer communities; and (2) mathematical funds of knowledge that youth have developed over time. The complexities of identifying mathematical practices in youth peer communities and leveraging them in schooled mathematics are discussed, as are implications for further research. 相似文献

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
