Two experiments investigated the use of orthographic analogies in 6 year olds. In Experiment 1, 26 children were shown CVC clue and target word pairs sharing either rimes (`fork' – `pork'), heads (`fork' – `ford') or were controls (`fork' – `hurl'). A modest advantage for rime-clued over head-cluedtargets was unreliable over by-subject and by-item analyses. Improvements in target word reading were correlated with pretest scaffolding errors (e.g. `pork' misread as `park'). In Experiment 2, 50 children were pretaught three clue words for each target word before being shown words that shared either rimes (`leak' – `peak'), or medial vowel digraphs (`leak') – `bean'), or were controls (`leak' – `herd'). A modest advantage for rime-clued over vowel digraph-clued targets was again unreliable over by-subject and by-item analyses. Neither rime nor phoneme awareness measures were correlated with rime inference use. Vowel, but not rime inference, was correlated with scaffolding errors. Rime detection was the strongest predictor of reading ability, whereas phoneme segmentation was the strongest predictor of the use of scaffolding errors. 相似文献

Lynne Cherry Brandwein Lecture March 2010 National Science Teachers Association (NSTA) Conference, Philadelphia, PA. Young
Voices on Climate Change: Inspired and Empowered Youth Tackle Climate Science and Find Climate Solutions. As a child, Lynne
Cherry was profoundly connected to the natural world and a special place. She watched the destruction of her world. Now, through
her Young Voices on Climate Change project, she is trying to give teachers and young people the tools to prevent planetary
meltdown on a greater scale. Global climate change is upon us and the need for education and action is immediate. Outreach,
visual storytelling, and scientific understanding are especially necessary in light of the recent polls that show that the
public is becoming more confused and less concerned about climate change. Cherry’s climate book, co-authored with photojournalist
Gary Braasch, and her Young Voices on Climate Change films feature climate solutions. They’re about win–win—save the environment,
protect human health, reduce global warming gases, demonstrate youth making a difference with practical tools, motivate engagement
in climate science, take pride in increased science literacy, reach young people through their hearts as well as their minds,
and save money. Although young people can help their parents, peers and communities understand climate science, they can also
show them that reducing CO2 is in their economic interest, and spur them to take action. School carbon reduction initiatives are spilling over into communities
yielding measurable results in both global warming gas reductions and significant monetary savings. 相似文献

The radial and axial motions of electrons in the betatron are described by means of a potential function of forces. Previously reported conditions of equilibrium, stability and damping of oscillations are derived for the region of parabolic variation of the potential. Extension of the analysis to, non-parabolic regions gives an account of the injection in conventional instruments in better agreement with experiment, particularly in regard to higher voltages of injection.Space charge limitations are discussed with the help of the Laplacian of the potential of forces.By means of an additional radial electric field electrons can be introduced as in the magnetron, without any asymmetry inherent in the conventional betatron circumferential injector. The analysis of the conditions of equilibrium and stability, greatly facilitated in this case by the notion of potential, shows that no substantial improvement in space charge limitations can be expected and that the required variations between the flux linking the electron orbits and the magnetic and electric fields at the orbits are difficult to realize on account of their complexity and narrow tolerances. The X-ray output of a small experimental double yoke instrument was measured by a phototube multiplier viewing an irradiated fluorescent screen and gave evidence of multiple group electron capture. 相似文献

Analysis of academic administrators’ attitudes: annual evaluations and factors that improve teaching
Brian D. Cherry Nathan Grasse Dale Kapla Brad Hamel 《Journal of Higher Education Policy & Management》2017,39(3):296-306
This article examines academic administrators’ attitudes towards the academic evaluation process in the US and those factors that are utilised to improve teaching. We use path regressions to examine satisfaction with evaluation procedures, as well as the direct and indirect effects of these factors on perceptions of whether the evaluation process facilitates quality instruction. With increased pressure for accountability being placed on higher education, it is important to ensure that we are meeting both public and academic expectations. The evaluation process is an important tool to ensure the university’s goals and values are articulated and that academics can be successful in their individual career paths. The problem is most research finds flaws with the current method of evaluation, and academics and academic administrators are sceptical about the process and results. We find there are environmental factors that influence academic administrators’ perceptions of academic evaluations and the ability to improve classroom instruction. 相似文献

Objective
We sought to determine the incidence, clinical features, and demographic profile of head injury secondary to suspected child maltreatment (abuse or neglect) in Canada to help inform the development and evaluation of prevention programs for abusive head injuries.Methods
From March 1, 2005 to February 28, 2008, an average of 2,545 paediatricians and paediatric subspecialists were surveyed monthly through the established network of the Canadian Paediatric Surveillance Program. We calculated incidence rates using the number of confirmed cases over the product of the duration of the study (3 years) and population estimates by age group.Results
There were 220 confirmed cases of head injury from suspected child maltreatment. The annual incidence rate was 14.1 per 100,000 for children less than 1 year of age and 1.4 per 100,000 for those less than 15 years. Seventy three percent (141) of cases involved infants less than 12 months of age and 52% (100) of cases involved infants less than 6 months of age. Seventy-five percent (165) of cases presented to the emergency room. With regard to outcome, 12% (27) of cases resulted in death and 45% (75) of survivors had neurological sequelae at discharge. Thirty percent (67) of all cases, as well as 30% (8) of deaths were previously known to child welfare authorities.Conclusion
This study provides an estimate of the rate of head injury secondary to suspected child maltreatment in Canada. The young age and poor medical outcomes of those involved highlights the need for prevention efforts that are implemented early in life. Given that a significant percentage of injured infants and children were already known to child welfare authorities, the study also highlights the need to establish and evaluate additional preventive efforts for parents and caregivers already in the child welfare system. 相似文献6.
Student perceptions of the information professions and their master's program in information studies
Joan M. Cherry Wendy M. Duff Nalini Singh Luanne Freund 《Library & information science research》2011,33(2):120-131
Library and information (LIS) education is undergoing a major transformation. During this time of change, there is a pressing need for data from all stakeholder groups to support strategic decisions within individual schools and across the discipline as a whole; students are a key stakeholder group. This paper reports on a 4-year study of master's students enrolled in an institution undergoing a transition toward an iSchool. The self-administered questionnaire was distributed to students enrolled in the Master of Information Studies program at the University of Toronto eight times: to incoming students in the fall term for 4 years, and to the entire student body in the spring term of those same years. The data collected from approximately 1000 questionnaires indicate that students arrive excited about the information professions and optimistic about employment opportunities. As they progress through the program, however, many are not satisfied with professional aspects of their program. They want courses that prepare them for their first professional position, and opportunities to gain experience, which they believe will increase their employability. The data from the 4-year period revealed fluctuations over the years, which indicates the value of examining longitudinal data. 相似文献

正坐落于沪江之滨的复旦,教授举止容姿都颇得魏晋风骨,学生中则多思想驰骋的实干家,这里比校训更出名的是"孵蛋精神"——自由而无用的灵魂。无拘的复旦,眉眼间自有一番海派风情。春色太好,不想教课了复旦大学又被戏称为"孵蛋大学",我校不是中国知名度最高的大学,也没有赏心悦目的海景校园,旦苑食堂特产的"哈密瓜炒苦瓜"和一路之隔的兄弟大学同济"大鸡排"相比,美味程度还是解放前后的差距。但复旦人偏不很看重 相似文献

This article explores Robert Kegan's adult constructive‐developmental (ACD) theory. We compare these ideas to the way educators at each of Kegan's meaning‐making levels might plan, implement, and assess digitally enhanced teaching activities. Using Drago‐Severson's interpretation of Kegan's concepts, the authors propose that behaviors of university teaching practitioners indicate mindsets evident at four ACD levels—instrumental, socialized, self‐authoring, and self‐transforming. Higher education professional development literature has identified a significant gap in practitioner implementation of interactive strategies using digital tools. If university practitioners increase their mental complexity they may become more adaptive in the application of interactive pedagogies and digital technologies. Adaptive approaches might cultivate new pedagogies supporting and challenging students toward more complex and flexible qualities of mind. 相似文献

The first paper published in the Journal of Research in Reading on the topic of phonological awareness ( Schreuder & van Bon, 1989 ) appeared some fifteen years after the seminal paper by Liberman, Shankweiler, Fischer and Carter (1974) , which had demonstrated that there was a relationship between spoken word segmentation ability and reading acquisition. That the field had moved on in those fifteen years is evident in the sophistication of the questions addressed by Schreuder and van Bon. I present here a brief summary of Schreuder and van Bon's paper, and explore how some of the issues they discuss have been developed over the subsequent fifteen years. 相似文献
