When reading in the classroom, teachers may use different methods. We examined the impact of different reading conditions on comprehension. Reading aloud involved reading the text aloud for an audience. Silent reading required the students to read the text silently. Follower reading involved listening to another student read the text aloud while having the text available for individual reading. Thirty-six fifth- and sixth-grade students read texts under the three conditions and then took comprehension tests. The students performed equally well under reading aloud and silent reading. Follower reading resulted in worse comprehension. The data suggest that the follower readers focused on their individual reading, making an effort not to listen to the student reading out loud, which consumed cognitive resources. Since reading aloud in the classroom involves not only one loud reader but also a lot of follower readers, silent reading might be the smartest choice.  相似文献   

The continuous nature of timing reprogramming in an interceptive task     

Luis Augusto Teixeira  Elke Dos Santos Lima  Mariana Marília Franzoni 《Journal of sports sciences》2013,31(9):943-950

The time course of movement timing reprogramming was examined in a task requiring temporal coincidence of the conclusion of a forehand drive with the arrival of a moving luminous target at the end of an electronic trackway. The moving target departed from one end of the trackway at a constant velocity of 2?m ^. s^?1, and for a part of the trials its velocity was increased to 3?m ^. s^?1. Target velocity was modified at different moments during stimulus displacement, producing times-to-arrival after velocity increment (TAVIs) from 100 to 600?ms. The effect of specific practice on movement reprogramming was also examined. The results showed early adjustments to the action (TAVIs = 100?–?200?ms) that seemed to be stereotyped, while feedback-based corrections were implemented only at TAVIs of 300?ms or longer. Temporal accuracy was progressively increased as longer TAVIs were provided up to 600?ms. Skill training led to an overall increment of temporal accuracy, but no effect of specific practice was found. The results indicate that timing reprogramming in interceptive actions is a continuous process limited mainly by intrinsic factors: latency to initiate more effective adjustments to the action, and rate-of-movement timing reprogramming.  相似文献   

Parallel assessment of nutrition and activity in athletes: Validation against doubly labelled water, 24-h urea excretion,and indirect calorimetry

Abstract

The assessment of nutrition and activity in athletes requires accurate and precise methods. The aim of this study was to validate a protocol for parallel assessment of diet and exercise against doubly labelled water, 24-h urea excretion, and respiratory gas exchange. The participants were 14 male triathletes under normal training conditions. Energy intake and doubly labelled water were weakly associated with each other (r = 0.69, standard error of estimate [SEE] = 304 kcal · day^?1). Protein intake was strongly correlated with 24-h urea (r = 0.89) but showed considerable individual variation (SEE = 0.34 g · kg^?1 · day^?1). Total energy expenditure based on recorded activities was highly correlated with doubly labelled water (r = 0.95, SEE = 195 kcal · day^?1) but was proportionally biased. During running and cycling, estimated exercise energy expenditure was highly correlated with gas exchange (running: r = 0.89, SEE = 1.6 kcal · min^?1; cycling: r = 0.95, SEE = 1.4 kcal · min^?1). High exercise energy expenditure was slightly underestimated during running. For nutrition data, variations appear too large for precise measurements in individual athletes, which is a common problem of dietary assessment methods. Despite the high correlations of total energy expenditure and exercise energy expenditure with reference methods, a correction for systematic errors is necessary for the valid estimation of energetic requirements in individual athletes.  相似文献   

A Multidimensional Analysis of the Disability Digital Divide: Some Evidence for Internet Use     

María Rosalía Vicente  Ana Jesús López 《The Information Society》2013,29(1):48-64

Over the last few years, information and communication technologies have become an essential part of daily life, affecting education, employment, and leisure, among other activities. Nonetheless, many individuals still reap few or no benefits from these technologies, and there are resilient gaps in their use. Within this larger context, the authors examine the Internet digital divide between people with and without disabilities from a multidimensional approach. Rather than analyzing the gap in terms of “haves” and “have-nots,” a range of Internet-related dimensions—affordability, motivation and attitudes, skills, usage, and others—is taken into account.  相似文献

Impact of a computer-based intervention in Chilean children at risk of manifesting reading difficulties / Impacto de una intervención basada en ordenador en niños chilenos con riesgo de manifestar dificultades lectoras     

Ricardo Rosas  María-Paz Ramírez  Alejandra Meneses  Alejandra Guajardo 《Infancia y Aprendizaje》2017,40(1):158-188

Reading difficulties have reached a prevalence of 3–10% in school-age children. Those who present these difficulties avoid reading and benefit very little from school-based learning opportunities, resulting in maladjustments, dropping out of school and having to repeat grades. Presented here are the results of an intervention based on a computer game intended for explicit phonic training in first-grade school children at risk of possessing reading difficulties. Fifty-six children from a low socioeconomic status (SES) and 31 children from a high socioeconomic status, divided into two groups (control and experimental), participated in the study. After the intervention, participants from the low-SES experimental group had enhanced their skills regarding letter sound recognition, whereas the high-SES experimental group had improved their naming speed. The results are discussed in light of the impact of interventions based on computer games and of the importance of the development of sublexical skills in children at risk of manifesting reading difficulties in transparent orthographies.  相似文献   

Relative Effects of English Proficiency on General Admissions Tests Versus Subject Tests   总被引：1，自引：0，他引：1  

Pennock-Román  María 《Research in higher education》2002,43(5):601-623

The increasing linguistic diversity of the United States student population has brought to the forefront problems in the interpretation of test scores for non-native speakers of English in graduate admissions. The degree to which test scores reflect English proficiency was studied using data on N = 451 students whose native language was Spanish. They had taken the GRE, English proficiency tests, and the PAEG, a test in Spanish used for admission to graduate schools in Puerto Rico. Regression analyses revealed that the proportion of variance explained by the English proficiency terms (independent of developed skills measured in Spanish) was highest for the GRE verbal test (34%), lowest for the quantitative test (8%) and intermediate for the analytical test (16%), the Psychology (18%) and Biology (17%) Subject tests. These findings are discussed in light of efforts to increase access to higher education for Hispanic students.  相似文献   

Pre-service teachers’ perceptions of social media data privacy policies     

Victoria I. Marín  Jeffrey P. Carpenter  Gemma Tur 《British journal of educational technology : journal of the Council for Educational Technology》2021,52(2):519-535

Matters of data privacy related to social media are increasingly relevant for educators as happenings such as the 2018 Cambridge Analytica scandal have attracted public attention. Many educators use social media for professional purposes, including with their students and should, therefore, be knowledgeable regarding data privacy issues that impact education. This research explores this issue from an interpretive paradigm based on a mixed-methods approach derived from survey data from an international sample of 148 pre-service teachers who were studying education courses at three universities. Data suggest that pre-service teachers see both educational and distracting potential in social media, but lack knowledge regarding relevant policies and regulations, which reflects trends in the broader population. Attitudes toward educational social media use were not correlated with awareness of data privacy policies. However, comfort with companies’ use of personal and student data and faith in governments’ capacity to regulate social media companies were correlated. We discuss our findings in relation to the use of social media and related data privacy considerations and the need for data literacy training in teacher education programs. We include recommendations in light of the findings.  相似文献   

Learning design and learning analytics in mobile and ubiquitous learning: A systematic review

Mobile and Ubiquitous Learning (m/u-learning) are finding an increasing adoption in education. They are often distinguished by hybrid learning environments that encompass elements of formal and informal learning, in activities that happen in distributed settings (indoors and outdoors), across physical and virtual spaces. Despite their purported benefits, these environments imply additional complexity in the design, monitoring and evaluation of learning activities. The research literature on learning design (LD) and learning analytics (LA) has started to deal with these issues. This paper presents a systematic literature review of LD and LA, in m/u-learning. Apart from providing an overview of the current research in the field, this review elicits elements of common ground between both communities, as shown by the similar learning contexts and complementary research contributions, and based on the research gaps, proposes to: address m/u-learning beyond higher education settings, reinforce the connection between physical and virtual learning spaces, and more systematically align LD and LA processes.  相似文献   

Critical thinking,executive functions and their potential relationship     

María Luisa Sanz de Acedo Lizarraga  María Teresa Sanz de Acedo Baquedano  Oscar Ardaiz Villanueva 《Thinking Skills and Creativity》2012,7(3):271-279

The central issue of this paper is to review the possible relationships between the constructs of critical thinking and executive functions. To do this, we first analyse the essential components of critical thinking from a psychological and neurological point of view. Second, we examine the scope of the cognitive and neurological nature of executive functions. Third, we propose a model for comparing or mapping between the most important processes of both constructs. Fourth, we offer some conclusions on the relational path between the two concepts based on the studies reviewed and suggest possible lines of investigation that will undoubtedly facilitate the understanding of shared features and key differences between critical thinking and executive functions.  相似文献
