Connecting Literacy and Science to Increase Achievement for English Language Learners     

Margarita Huerta  Julie Jackson 《Early Childhood Education Journal》2010,38(3):205-211

Giving students a purpose and a passion for sharing their thinking through authentic learning experiences and giving them tools for writing through which they can risk new vocabulary, new language, and new thought is critical for the linguistic and cognitive development of students. Furthermore, students develop a deep understanding of content they have heard and read when given time to process information through writing and speaking. This article describes one teacher’s quest to identify and implement effective research-based instructional strategies that she could use to successfully support her kindergarten ELL students during science instruction.  相似文献   

Classroom contextual effects of race on children's peer nominations     

Jackson MF  Barth JM  Powell N  Lochman JE 《Child development》2006,77(5):1325-1337

Black children generally receive poorer sociometric nominations compared with Whites. This effect is not fully understood because Black children rarely hold a classroom majority and teachers' race is rarely investigated. Research from a person-environment perspective suggests that the effects of children's race depend on the racial composition of the classroom and society's racial attitudes. Sociometric nominations were obtained from 1,268 5th graders, between 9 and 11 years old (53% Black), across 57 classrooms (3-95% Black students). Half of the teachers were Black. The results indicated that ratings of Black children were more influenced by the racial context of classrooms than were ratings of White children. The implications of this study are discussed in relation to group dynamics and racial discrimination.  相似文献   

Images of Objective Knowledge Construction in Sexual Selection Chapters of Evolution Textbooks

Textbooks provide a rich site within which to investigate how members of a scientific discipline choose to represent their research to general audiences. We used critical contextual empiricism as a framework for interrogating how a scientific community is depicted via images in evolution textbook chapters on sexual selection. Textbooks that exhibit science within the tenets of critical contextual empiricism will depict uptake of disciplinary change and acknowledge the inseparability of the social and rational aspects of scientific knowledge construction. Sexual selection is an exemplary arena for this work because the field has undergone substantial change in the past few decades that has been driven by critique from within and among disciplines. We used quantitative methods and content analysis to examine images from the textbook editions and from a time series of editions to examine the portrayal of updated understandings of sexual selection. We found that most textbook images did not reflect the shift happening in the scientific community. Images highlighted primarily the classic view of sexual selection focused on males. Examples typical of a more realistic, complicated understanding received little attention even though the scientific literature on these topics appeared decades before these textbooks were published. Images of males were more common than images of females, females were depicted for fewer concepts than males, and images of males and females reinforced stereotypical sex roles. This study highlights an opportunity for acknowledging the inseparability of the social and the rational in scientific knowledge construction.  相似文献   

Acute short-term sleep deprivation does not affect metacognitive monitoring captured by confidence ratings: a systematic literature review     

Simon A. Jackson  Gregory D. Martin  Eugene Aidman  Sabina Kleitman 《Metacognition and Learning》2018,13(1):39-56

This article presents the results of a systematic review of the literature surrounding the effects that acute sleep deprivation has on metacognitive monitoring. Metacognitive monitoring refers to the ability to accurately assess one’s own performance and state of knowledge. The mechanism behind this assessment is captured by subjective feelings of confidence concerning the accuracy of our judgments or performance. These judgments influence decision behavior. How well these subjective feelings fit with reality is critical for good decision making. For example, a driver who is overconfident in their ability to remain vigilant after a night without sleep is at risk of having an accident. A learner who is overconfident in their ability to perform well on an exam without sleep is at risk of failing. A break down in metacognitive monitoring might be responsible for the increase in poor decision making observed when people are sleep deprived. Using defined search terms and exclusion criteria, electronic database searches identified ten empirical studies suitable for review. Participants in these studies completed performance-based tasks, typically cognitive, while remaining awake for 28–63 hours. In all studies, metacognitive monitoring was assessed via confidence ratings either pre-, on-, or post-task. Extended wakefulness had a significant negative effect on performance in most studies. Evidencing good monitoring, however, the monitoring estimates such as confidence also tended to decline. Moreover, two critical variables that assess the fit of these estimates to actual performance (bias and discrimination) were mostly unaffected by the number of hours awake. Still, some results indicated that these variables may be affected by substances intended to fight sleep deprivation, such as modafinil. Within the limitations of extant literature (e.g., a sampling bias towards young adult male participants), empirical observations to date converge to suggest that metacognitive monitoring remains largely unaffected by the examined quantities of acute sleep deprivation (up to 63 hours).  相似文献

Objective:Since concussion is the most common injury in ice hockey,the objective of the current study was to elucidate risk factors,specific mechanisms,and clinical presentations of concussion in men’s and women’s ice hockey.Methods:Ice hockey players from 5 institutions participating in the Concussion Assessment,Research,and Education Consortium were eligible for the current study.Participants who sustained a concussion outside of this sport were excluded.There were 332(250 males,82 females)athletes who participated in ice hockey,and 47(36 males,11 females)who sustained a concussion.Results:Previous concussion(odds ratio(OR)=2.00;95%confidence interval(95%CI):1.02‒3.91)was associated with increased incident concussion odds,while wearing a mouthguard was protective against incident concussion(OR=0.43;95%CI:0.22‒0.85).Overall,concussion mechanisms did not significantly differ between sexes.There were specific differences in how concussions presented clinically across male and female ice hockey players,however.Females(9.09%)were less likely than males(41.67%)to have a delayed symptom onset(p=0.045).Additionally,females took significantly longer to reach asymptomatic(p=0.015)and return-to-play clearance(p=0.005).Within the first 2 weeks post-concussion,86.11%of males reached asymptomatic,while only 45.50%of females reached the same phase of recovery.Most males(91.67%)were cleared for return to play within 3 weeks of their concussion,compared to less than half(45.50%)of females.Conclusion:The current study proposes possible risk factors,mechanisms,and clinical profiles to be validated in future concussions studies with larger female sample sizes.Understanding specific risk factors,concussion mechanisms,and clinical profiles of concussion in collegiate ice hockey may generate ideas for future concussion prevention or intervention studies.  相似文献

Page 22 The Organizaitonal Scan     

Donald T Tosti  Stephanie F. Jackson 《Performance Improvement》1997,36(10):39-40

Performance technologists are likely to face at least two kinds of large-scale efforts. In one, the performance technologist is presented with a big issue to address; in the other, with a big program to make successful. This presents problems in implementing analysis: the results of the analysis must correspond to the size of the effort, but the project's sponsors want to see progress. The ideal approach, then, would be one that produces short-term benefits yet is not expensive or time-consuming. The organizational scan model can help performance technologists do a complete analysis without running up costs or wasting time. The keyword is “scan,” for the performance technologist will review the processes and traits of the organization, yet not place the organization under a microscope. The model is systemic, comprehensive, manageable, and communicable. It will help the performance technologist to identify actions that can be taken immediately to improve performance. From there the performance technologist can set priorities and plan further interventions to be used as necessary.  相似文献
