Research on the utilization of the Web for complex fine motor skill learning that involves whole body movements is still scarce. The aim of this study was to evaluate the impact of the introduction of a multimedia web-based learning environment, which was targeted at a rhythmic gymnastics routine consisting of eight fine motor skills, into an undergraduate course in a physical education department, as a complementary tool to campus-based instruction. The impact was evaluated in terms of: acquisition of knowledge regarding the routine skills by students, improvement of students’ ability to execute the routine, and students’ responses to the environment. The study followed a pretest/posttest experimental design and involved 76 students randomly split into two groups: The Multimedia Web-based Learning Group (MWLG) students (N?=?38), who attended campus-based instruction on the routine and also used the environment in their own space and time, and the Traditional On-site Instruction Group (TOIG) students (N?=?38), who only attended campus-based instruction. The research data were gathered through student questionnaires and ratings of students’ performances. It was found that the use of the environment as a supplement to campus-based instruction increased the effectiveness of this instruction as regards the cognitive component of motor skill learning (i.e. acquisition of knowledge regarding the routine skills) and was well-accepted by the students, although it did not have any significant contribution to the physical component of motor skill learning (i.e. performance of the routine skills). These findings partially support the future wider adoption of multimedia web-based learning environments within physical education and other academic disciplines that involve complex fine motor skill learning. Relevant implications are discussed.  相似文献

The purpose of the paper is to examine the impact of internationalization on innovation. Specifically we explored the impact of internationalization on firms' choice for research and development (R&D) approach and technology source, impact of choice for research and development (R&D) approach and technology source on innovation and finally impact of business hampering factors on innovation. We had focused on innovation intensity to measure impact on innovation. A survey of foreign investment enterprises in Croatia was conducted. A total of 145 firms responded to the questionnaire. Multivariate analyses are used to analyze the data. In addition we identified key factors impacting different types of innovation.  相似文献

This article describes ROODA (), a virtual learning environment and one of the official Long Distance Education platforms that has been in use since 2005 at the Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, Brazil. It is free software that integrates syncronous and assyncronous interaction/communication tools and publications. In this study, details about institutional demands in relation to long distance education are discussed and ROODA is described with the components that were part of its development such as: modelling and programming, graphic interface and documents for users. Moreover, 19 functions were conceived. Finally, project investigation paths are presented where the platform described is inserted.

Because random assignment is not possible in observational studies, estimates of treatment effects might be biased due to selection on observable and unobservable variables. To strengthen causal inference in longitudinal observational studies of multiple treatments, we present 4 latent growth models for propensity score matched groups, and evaluate their performance with a Monte Carlo simulation study. We found that the 4 models performed similarly with respect to model fit, bias of parameter estimates, Type I error, and power to test the treatment effect. To demonstrate a multigroup latent growth model with dummy treatment indicators, we estimated the effect of students changing schools during elementary school years on their reading and mathematics achievement, using data from the Early Childhood Longitudinal Study Kindergarten Cohort.  相似文献

ABSTRACT

This study examined how work–family conflict (WFC) is associated with mechanisms of relational turbulence, conflict tactics, and marital satisfaction. Six hundred and thirty-three married workers completed an online survey. Family interference with work and spouses’ work interfering with one’s family predicted greater relational uncertainty and interference from partners, whereas one’s own work interfering with family did not predict these mechanisms of turbulence. All three sources of relational uncertainty, and interference from partners, predicted increased avoidance and distributive tactic use. Facilitation from partners predicted increased use of integrative tactics. Finally, relational uncertainty, interference from partners, and distributive conflict tactics partially mediated the associations of WFC with marital satisfaction.  相似文献

This longitudinal study investigated the effects of maternal emotional health concerns, on infants’ home language environment, vocalization quantity, and expressive language skills. Mothers and their infants (at 6 and 12 months; 21 mothers with depression and or anxiety and 21 controls) provided day-long home-language recordings. Compared with controls, risk group recordings contained fewer mother–infant conversational turns and infant vocalizations, but daily number of adult word counts showed no group difference. Furthermore, conversational turns and infant vocalizations were stronger predictors of infants’ 18-month vocabulary size than depression and anxiety measures. However, anxiety levels moderated the effect of conversational turns on vocabulary size. These results suggest that variability in mothers’ emotional health influences infants’ language environment and later language ability.  相似文献

ABSTRACT

This study examines academic outcomes for university students engaged in a supplemental peer learning program in a selective institution. Using a matched sample of 1266 students, half enrolled in the supplemental program and half not enrolled, we find that participating students on average earned higher grades in linked courses. Using a subsample of students in a chemistry course sequence, we find program participants were more likely to remain in the sequence than non-participants, and that the impact was greater for students with lower levels of preparation.  相似文献

The article explores the long‐term effectiveness of in‐service teacher training courses for English as a Foreign Language (EFL) teachers in the Greek educational context. It presents the results of a questionnaire designed and issued to teacher‐trainees a year after the completion of 60‐hour courses. The questionnaire assessed, among others, (a) teacher trainees' beliefs regarding the relevance of the knowledge acquired to their individual needs, (b) the extent to which they used the materials provided in the course, and (c) the usefulness of the subjects offered. The data are discussed in relation to strategies for optimising teacher training services and implications are drawn for the implementation of change in a broader educational context. A ‘cooperative model' is proposed for the promotion of change involving active cooperation between all agents involved in the educational process and necessitating top‐down and bottom‐up cooperation.  相似文献

对20世纪30年代新文学史的编纂和对新文学作品的选编,需要与当时的社会和文化境况,特别是与当时的文化争论紧密联系起来.重读这些资料,有助于我们今天对当时文化界境况的了解,而且也可以重温当时对新文学的评价,从中可见五四运动的一些主要人物再三重申并肯定五四理想,同时也表现出他们的一些不自信和担心.他们反思到:他们生命中的一段历程结束了,与之诞生的文学也行将告一段落.总之,可以推想:20世纪30年代新文学史的编纂和新文学作品的选辑,并不是五四全盛时期的硕果,而是人们对轰轰烈烈的五四运动的深切留恋,<中国新文学大系>尤其可以算是为了已结束的文化时代,也为了自己一代人所作出的贡献而建立的一座纪念碑.  相似文献
