Examining Child and Word Characteristics in Vocabulary Learning of Struggling Readers     

Amy M. Elleman  Laura M. Steacy  Natalie G. Olinghouse  Donald L. Compton 《Scientific Studies of Reading》2017,21(2):133-145

Although instruction has been shown to be effective at increasing vocabulary knowledge and comprehension, factors most important for promoting the acquisition of novel vocabulary are less known. In addition, few vocabulary studies have utilized models that simultaneously take into account child-level, word-level, and instructional factors to better understand the acquisition of novel vocabulary from informational text. Sixty-eight children with reading difficulties in Grades 3–5 were randomly assigned to either vocabulary strategy instruction or traditional comprehension instruction with both groups reading the same set of expository texts. Crossed random-effects models were used to predict item-level variance in vocabulary acquisition. Results indicated main effects for condition favoring vocabulary instruction, child-level predictors (vocabulary and knowledge of the content), and word-level factors (frequency and imageability). One interaction was significant, indicating that students with higher vocabulary scores were more likely to do better when provided vocabulary instruction than students with lower prior vocabulary.  相似文献

The Impact of On-campus Student Growth on First-year Student Engagement and Success     

Steven M. LaNasa  Elizabeth Olson  Natalie Alleman 《Research in higher education》2007,48(8):941-966

During the past two decades institutions of all types have sought to expand and enhance residential facilities. Institutional focus on scale, configuration, amenities, and academic integration has sought to leverage prior research documenting the multiple and often positive impacts of on-campus residence. Although institutional size has been documented to differentially impact student engagement [Kezar, A. J. (2006). NASPA Journal 43(1): 87–114], few studies, however, have directly explored the effect of residential expansion on student engagement. This study, based on a sample of 731 first-time freshmen explores NSSE results before and after the opening of a residential facility that doubled on-campus living at a single, metropolitan institution. Results indicate limited positive differences after opening, and suggest that structure, in the form of size, does not, in and of itself, contribute significantly to shifting engagement. Additionally, these results suggest an alternative method for using NSSE data in institutional analyses.  相似文献   

Who drops out from primary schools in China? Evidence from minority-concentrated rural areas

One of the Millennium Development Goals is to ensure universal access to primary education by 2015. However, primary school dropout remains a challenge in many developing countries. While official statistics in China report aggregated primary school dropout of only 0.2 %, almost no independent, survey-based studies have sought to verify these dropout rates in rural areas. The primary objective of our study is to document the dropout rate in primary schools in rural China and compare the dropout rate of ethnic minorities and Han students. Using a first-hand dataset of 14,761 primary students in northwest China, we demonstrate that the annual dropout rate in poor rural areas is 2.5 %, suggesting a cumulative dropout of 8.2 %. Importantly, Hui and Salar minority students drop out at rates that are significantly higher than the official rates. Most noteworthy, 23 % of Hui girls and 22 % of Salar girls are dropping out by the end of grade 6. Our findings call for more attention to China’s primary school dropout issue—especially in minority areas. Policymakers should begin to examine new ways to increase the chances for minority students to succeed in the educational system.  相似文献   

Alternative models of entrance exams and access to higher education: the case of the Czech Republic     

Tomá? Kone?ny  Josef Basl  Jan Myslive?ek  Natalie Simonová 《Higher Education》2012,63(2):219-235

The study compares the potential effects of a university admission exam model based on program-specific knowledge and an alternative model relying on general study aptitude (GSA) in the context of a strongly stratified educational system with considerable excess of demand over supply of university education. Using results of the Sonda Maturant 1998 survey, we show that in the specific context of the Czech Republic, displaying the above characteristics in the given period, an admission exam model based on general study aptitude tests may improve the access of talented individuals with lower socioeconomic status to university education. Our simulations show that with the GSA model (provided the model assumptions are met), the relative chances of an applicant with a university-educated father would be only by one-fourth higher than the relative chances of a student with a less educated father, as compared to the more than a one-third difference in case of the model emphasizing program-specific knowledge. The odds ratio for the GSA model is by 28% points lower for mother’s education.  相似文献   

Research–practice interactions as reported in recent design studies: still promising, still hazy     

Bart J. B. Ormel  Natalie N. Pareja Roblin  Susan E. McKenney  Joke M. Voogt  Jules M. Pieters 《Educational technology research and development : ETR & D》2012,60(6):967-986

This study portrays recent research?Cpractice connections found in 18 design research reports focusing on the creation of instructional solutions. Solutions in different stages of development varied greatly in duration, ranging from one lesson to a whole year curriculum, spanned all levels of education, many subjects (science, math, language, culture, teacher education, etc.). Close collaboration between researchers and practitioners was prominent in all of the 18 projects studied. Participants in primary and secondary education projects have quite distinct roles regarding the teaching and researching, but they design their instruction solutions often collaboratively. Nearly all projects reported on how designed solutions were anchored in research, either from literature or from in-house project data. All articles indicated that research fed (re-)design, but few specified how. Based on our findings, we call for increased research and reporting on the specific strategies employed by design research participants to facilitate the production of new theoretical understanding through design of instructional solutions.  相似文献

UpToDate versus DynaMed: a cross-sectional study comparing the speed and accuracy of two point-of-care information tools     

Glyneva Bradley-Ridout  Erica Nekolaichuk  Trevor Jamieson  Claire Jones  Natalie Morson  Rita Chuang  Elena Springall 《Journal of the Medical Library Association》2021,109(3):382

Objective:To compare the accuracy, time to answer, user confidence, and user satisfaction between UpToDate and DynaMed (formerly DynaMed Plus), which are two popular point-of-care information tools.Methods:A crossover study was conducted with medical residents in obstetrics and gynecology and family medicine at the University of Toronto in order to compare the speed and accuracy with which they retrieved answers to clinical questions using UpToDate and DynaMed. Experiments took place between February 2017 and December 2019. Following a short tutorial on how to use each tool and completion of a background survey, participants attempted to find answers to two clinical questions in each tool. Time to answer each question, the chosen answer, confidence score, and satisfaction score were recorded for each clinical question.Results:A total of 57 residents took part in the experiment, including 32 from family medicine and 25 from obstetrics and gynecology. Accuracy in clinical answers was equal between UpToDate (average 1.35 out of 2) and DynaMed (average 1.36 out of 2). However, time to answer was 2.5 minutes faster in UpToDate compared to DynaMed. Participants were also more confident and satisfied with their answers in UpToDate compared to DynaMed.Conclusions:Despite a preference for UpToDate and a higher confidence in responses, the accuracy of clinical answers in UpToDate was equal to those in DynaMed. Previous exposure to UpToDate likely played a major role in participants'' preferences. More research in this area is recommended.  相似文献   

Instance-based cognitive mapping: a process for discovering a knowledge worker's tacit mental model     

David M?SteigerEmail author  Natalie M?Steiger 《知识管理研究与实践》2008,6(4):312-321

This paper addresses tacit-to-explicit knowledge externalization, arguably the most critical, and yet problematic, phase of Nonaka's knowledge creation theory. Specifically, we propose and describe instance-based cognitive mapping (ICM), a unique externalization process that analyzes multiple decision instances using the inductive learning algorithms of artificial intelligence to generate a polynomial representation of the knowledge worker's mental model, explicitly relating how the knowledge worker implicitly selects and weighs key factors in making decisions within a specific problem domain. After reviewing current externalization techniques, we describe the characteristics, and evaluate the advantages, of the ICM process. An exploratory test of the process suggests that inductive learning algorithms, such as the group method of data handling, can be used to discover a reasonable polynomial estimate of a knowledge worker's tacit mental model. This estimate can then be compared with other explicit models and standards, updated with new information and knowledge, and internalized by all interested knowledge workers.  相似文献
