The purpose of the present study was to explore the 3rd-grade cognitive predictors of 5th-grade computational skill with rational numbers and how those are similar to and different from the cognitive predictors of whole-number computational skill. Students (n = 688) were assessed on incoming whole-number calculation skill, language, nonverbal reasoning, concept formation, processing speed, and working memory in the fall of 3rd grade. Students were followed longitudinally and assessed on calculation skill with whole numbers and with rational numbers in the spring of 5th grade. The unique predictors of skill with whole-number computation were incoming whole-number calculation skill, nonverbal reasoning, concept formation, and working memory (numerical executive control). In addition to these cognitive abilities, language emerged as a unique predictor of rational-number computational skill. 相似文献

Although interactive technology is presumed to increase student understanding in large classes, no previous research studies have empirically explored the effects of Clicker Cases on students?? performance. A Clicker Case is a story (e.g., a problem someone is facing) that uses clickers (student response systems) to engage students in understanding the meaning of the science contained within the story. Using an experimental randomized Solomon design across 11 institutions, we found that Clicker Cases increased student understanding more than PowerPoint lectures in large introductory biology classrooms, although there was variation across institutions and topics. By examining student performance in conjunction with faculty experience, we found that strong Clicker Cases created dissonance, captured attention and involved students in interpreting data or making decisions. This study provides a model for collaborative research across multiple institutions and demonstrates the need for using multiple institutions and topics in research on education. 相似文献

Peer assessment provides students with multiple benefits during their learning process. The aim of our study is to examine students’ perception of peer assessment. Questionnaires were administered before and after the peer-assessment process to 416 students studying 11 different subjects in four different fields taught at the University of Girona. Results suggest that students have a positive predisposition towards this methodology, both before and after its implementation. Students perceive it as a both motivating and recommended methodology that facilitates the acquisition of learning at different levels. As for its limitations, students highlight the responsibility that comes with it and a certain amount of distrust in fellow students’ abilities to peer-assess. 相似文献

Although screening for child abuse at emergency departments (EDs) increases the detection rate of potential child abuse, an accurate instrument is lacking. This study was designed to measure the accuracy of a screening instrument for detection of potential child abuse used in EDs. In a prospective cohort study at three Dutch EDs, a 6-item screening instrument for child abuse, Escape, was completed for each child visiting the ED. The data from the completed Escape instrument was used to calculate sensitivity, specificity, and the positive/negative predictive value per item. The clinical notes and conclusions of the screen instruments of all potentially abused children reported to the hospitals’ Child Abuse Teams were collected and reviewed by an expert panel. A logistic regression model was used to evaluate the predictors of potential abuse. Completed Escape instruments were available for 18,275 ED visits. Forty-four of the 420 children with a positive screening result, and 11 of the 17,855 children with a negative result were identified as potentially abused. Sensitivity of the Escape instrument was 0.80 and specificity was 0.98. Univariate logistic regression showed that potentially abused children were significantly more likely to have had an aberrant answer to at least one of the items, OR = 189.8, 95% CI [97.3, 370.4]. Most of the children at high risk for child abuse were detected through screening. The Escape instrument is a useful tool for ED staff to support the identification of those at high risk for child abuse. 相似文献

Higher education in developing nations is typically viewed from a dependency perspective – institutions are seen as merely recipients of Western knowledge, aid and reform efforts. Nevertheless, universities in both the centre and the periphery are dealing with tensions between protecting the public good and embracing neoliberal values based on a market approach to higher education. In the USA and Europe these competing interests are typically cast as mutually exclusive. Our study on the market approach to higher education in Kenya, however, suggests that public and private interests can be complementary, contributing to a re-envisioning of the traditional mission of higher education. This article seeks to examine more fully the nature of reform efforts at two universities in Kenya, to elucidate lessons for universities undergoing market-oriented reform in the West and to suggest a reciprocal relationship between institutions in Africa and Europe, upending the centre-periphery paradigm. 相似文献

This paper takes the case of math educationreform in California to analyze problems andprospects for reforming high school teaching.The experiences of three math departmentsreveal the profoundly political nature of highschool mathematics reform. First, changing mathinstruction means rejecting established normsfor professional practice in mathematics and inteaching more generally. I argue that radicalteaching reform depends upon professionalismand sustained commitment of teachercommunities, as well as on the knowledge ofreformed practice they generate. Second,successful reform engages politics beyond theteaching profession, as the California ``mathwars' attest. After describing the course oforganized opposition to a reformed high schoolmath department, I examine the rhetoric andvested interests that figure prominently inparents' mobilization against mathematicsreform. The analysis brings into focus the dualproblems for high school teaching reform ofchanging professional practice and engagingpolitical opposition to educational change. Thestunning success of anti-reform politics inAmerican mathematics education highlights theimportance of activist professionalism inteaching. 相似文献

Coronavirus disease 2019 (Covid-19) created unparalleled challenges to anatomy education. Gross anatomy education has been particularly impacted given the traditional in-person format of didactic instruction and/or laboratory component(s). To assess the changes in gross anatomy lecture and laboratory instruction, assessment, and teaching resources utilized as a result of Covid-19, a survey was distributed to gross anatomy educators through professional associations and listservs. Of the 67 survey responses received for the May–August 2020 academic period, 84% were from United States (US) institutions, while 16% were internationally based. Respondents indicated that in-person lecture decreased during Covid-19 (before: 76%, during: 8%, P < 0.001) and use of cadaver materials declined (before: 76 ± 33%, during: 34 ± 43%, P < 0.001). The use of cadaver materials in laboratories decreased during Covid-19 across academic programs, stand-alone and integrated anatomy courses, and private and public institutions (P ≤ 0.004). Before Covid-19, cadaveric materials used in laboratories were greater among professional health programs relative to medical and undergraduate programs (P ≤ 0.03) and among stand-alone relative to integrated anatomy courses (P ≤ 0.03). Furthermore, computer-based assessment increased (P < 0.001) and assessment materials changed from cadaveric material to images (P < 0.03) during Covid-19, even though assessment structure was not different (P > 0.05). The use of digital teaching resources increased during Covid-19 (P < 0.001), with reports of increased use of in-house created content, BlueLink, and Complete Anatomy software (P < 0.05). While primarily representing US institutions, this study provided evidence of how anatomy educators adapted their courses, largely through virtual mediums, and modified laboratory protocols during the initial emergence of the Covid-19 pandemic. 相似文献

This account tells the story of the development of an action learning culture in the BBC between 2002 and 2007. From its early beginnings as a sporadic, unsystematic intervention with a small number of leaders scattered throughout the organisation, action learning has now become embedded in our approach to the way we develop our leaders. In this paper we look at the organisational context in which we were developing action learning, the way it became an integral part of a systemic change intervention, the barriers we had to overcome on the way, how we built an internal resource capability and how action learning evolved. We evaluate the impact it has had on the organisation and on our practice, exploring lessons learned during this time and offering ideas for the way ahead. 相似文献
