The concept of science in the schoolhouse combines knowledge of research-based practices with the complexities of day-to-day life in schools. In this discussion, co-teaching is offered as an example of how advocacy for a practice can outpace the science that supports it. There is a push for co-teaching in contemporary schools, and special educators in great numbers are being asked to join with general educators in meeting the needs of students with disabilities. However, the science behind co-teaching to date is very limited. Studies have examined the implementation of co-teaching as a general service delivery option, but much less attention has been paid scientifically to the character and quality of the co-taught instruction or to the impact of co-teaching on student outcomes. Within this context, I also examine how Crockett's four recommendations to support science in the schoolhouse could address the questions about co-teaching for which there are few answers.  相似文献

Research Findings: Big Math for Little Kids (BMLK) is a mathematics curriculum developed for use with 4- and 5-year-old children. To investigate the BMLK curriculum's effect on children's mathematics knowledge, this cluster-randomized controlled trial randomly assigned child care centers to provide mathematics instruction to children, using either the BMLK mathematics curriculum or the centers’ business-as-usual curriculum, over a 2-year period when children were in prekindergarten and kindergarten. Participants in the study were 762 children and their teachers at 16 publicly subsidized child care centers. The study assessed children's mathematics knowledge using the Early Childhood Longitudinal Study, Birth Cohort (ECLS-B), Direct Mathematics Assessment, a measure of young children's mathematics knowledge that is not aligned with the curriculum. The ECLS-B scores of children in the BMLK group increased significantly more than did those of children in the comparison group. The study also included exploratory analyses to examine whether children in the BMLK group demonstrated evidence of improved mathematical language. Practice or Policy: These results indicate that the BMLK curriculum, which is designed to help teachers use play-based, developmentally appropriate mathematics instruction, has a positive impact on young children's mathematics knowledge as measured by a general mathematics assessment that is not aligned with the curriculum.  相似文献

Ability and personality test scores of 256 males, categorized by college persistence seven semesters after matriculation, were subjected to stepwise discriminant analysis. A combination of personality and ability variables distinguished between groups (p<.001); personality variables alone did not. The most powerful discriminator was overall ability. Authoritarianism, natural science ability, and nonconformity also entered into the discrimination. Results indicate: (a) the most able, most autonomous group included those who withdrew; (b) the most authoritarian, those who became seniors; (c) the most nonconforming, those who continued without becoming seniors, and (d) the highest in ability to think abstractly and scientifically and to solve problems, the academic dismissals who with difficulty succeeded in gaining reinstatement.  相似文献

The discussion of problems associated with the use of language, specifically vocabulary and symbolism, is extended from the teaching and learning of mathematics to the particular area of statistics.  相似文献

Despite instructors' belief that class readings are integral to the learning process, only 20–30% of undergraduate students complete required readings. Failure to complete course reading has been associated with declines in exam and research performance. This article first offers a brief review of the literature on why students do not complete course readings: 1) unpreparedness, 2) lack of motivation, 3) time constraints, and 4) an underestimation of reading importance. We then identify approaches that encourage students to read, enjoy reading, and develop metacognitive knowledge, shown to improve learning.  相似文献

It is known that biotic interactions are the key to species coexistence and maintenance of species diversity. Traditional studies focus overwhelmingly on pairwise interactions between organisms, ignoring complex higher-order interactions (HOIs). In this study, we present a novel method of calculating individual-level HOIs for trees, and use this method to test the importance of size- and distance-dependent individual-level HOIs to tree performance in a 25-ha temperate forest dynamic plot. We found that full HOI-inclusive models improved our ability to model and predict the survival and growth of trees, providing empirical evidence that HOIs strongly influence tree performance in this temperate forest. Specifically, assessed HOIs mitigate the competitive direct effects of neighbours on survival and growth of focal trees. Our study lays a foundation for future investigations of the prevalence and relative importance of HOIs in global forests and their impact on species diversity.  相似文献

Children learn to read at approximately the same stage in life as they start to master their physical environment. This article argues that some of the same mapping and schema-building strategies inform each activity, and draws on examples from a broad range of children’s books to support the idea that reading fiction and mapping one’s local surroundings work in tandem among many young children. Fictional examples include Ramona the Brave, The Moffats, and The House at Pooh Corner. As children grow, and their understanding of their own world increases, their relationship with fiction may become more complex; this proposal is discussed in relation to the works of Carolyn Keene and Enid Blyton.  相似文献

The thesis by publication (TBP) is an increasingly popular approach to doctoral education that sees candidates publishing their research during their candidature, and including these outputs in their final thesis submission. Responsive to the realities of modern academia, a TBP provides doctoral candidates with opportunities to engage in the scholarly publication process, and to build their research portfolio. As the TBP gains further traction in many fields and countries, there is a need to better understand the skills and attributes needed to complete a TBP successfully. This paper draws on the views of 246 recent doctoral graduates of Australian universities to identify the skills and attributes they felt supported their success. Their responses have implications for the development and refinement of institutional policies and programs that are sensitive to the needs and experiences of doctoral candidates seeking to publish during candidature and create a TBP. As editors, peer‐reviewers, and publishers see a growing influx of papers sole‐ or co‐authored by doctoral candidates in response to the trend toward TBP, they may find themselves involved in supporting students to develop the skills and attributes needed to successfully publish during candidature.  相似文献
