Audio-visual training in children with reading disabilities   总被引:1,自引:0,他引:1  
This study tested the effectiveness of audio-visual training in the discrimination of the phonetic feature of voicing on the recognition of written words by young children deemed to at risk of dyslexia (experiment 1) as well as on dyslexic children’s phonological skills (experiment 2). In addition, the third experiment studied the effectiveness of this word recognition training in dyslexic children who regularly used a computer at home. A traditional pre-test, training, post-test design including comparison groups (experimental vs. control) provided a base-line for assessing the training effects. In the three experiments the intervention group showed higher increases performances in phonological skills and phonological recoding than the control group did. Beyond providing evidence for the effectiveness of this audio-visual training, these results contribute to an understanding of the nature of reading difficulties and successful training. Globally, the results show the impact of the audio-visual training about voicing on performances of reading-disabled children. A such type of training leads children to connect print and phonology. Phonological representations could be specified by training which involves both phonological and orthographic units. The mapping between these two units could be easier in a computerized remedial program.  相似文献

This study examines the effects of a computer-assisted learning (CAL) program in which syllabic units were highlighted inside words in comparison with a CAL program in which the words were not segmented, i.e. one requiring whole word recognition. In a randomised control trial design, two separate groups of French speaking poor readers (2 * 14) in first grade were constituted. They were matched on a range of reading measures and non verbal intelligence and trained intensively over a short period (10 h over a period of 5 weeks). Three tasks were proposed using a classical pre-test/training/post-test design, written word recognition, word reading aloud and word spelling. In addition, three post-test sessions were conducted: one just after training, one after 4 months, and a last one after 9 months. The experimental group trained with the CAL using syllabic units outperformed the control group using CAL with whole word recognition in all the three tasks and there were important lasting effects. The results are discussed in the light of the self-teaching hypothesis and phonological recoding.  相似文献

Competition, despite its potential drawbacks, is an easily adopted and frequently used motivator in classrooms. Individual abilities, in the years of schooling, are inevitably different, and performance in competition is heavily ability dependent, resulting that more-able students always win while less-able students always lose. Students easily perceive how well they perform through the result of competition, which is termed as perceived performance in this paper. Consistently demonstrating lower perceived performance than their peers, the less-able students feel discouraged and frustrated, hardly having the same opportunity for owning the sense of achievement as the more-able students. In this study, the authors designed a computerized mechanism, equal opportunity tactic, to lessen the difference in perceived performance between more-able and less-able students. Equal opportunity tactic is incorporated into a version of a competitive learning game called AnswerMatching, in which every student is assigned an opponent with similar ability. An experiment was also conducted to preliminarily investigate the effectiveness and effects of the tactic. Results showed that equal opportunity tactic could reduce the effect of individual ability difference on the perceived performance as well as the belief about how well students could achieve. In other words, less-able students could have similar opportunity of success and build confidence similar to more-able students in a competition.  相似文献

The ‘will, skill, tool’ model is a well-established theoretical framework that elucidates the conditions under which teachers are most likely to employ information and communication technologies (ICT) in the classroom. Past studies have shown that these three factors explain a very high degree of variance in the frequency of classroom ICT use. The present study replicates past findings using a different set of measures and hones in on possible subfactors. Furthermore, the study examines teacher affiliation for constructivist-style teaching, which is often considered to facilitate the pedagogical use of digital media. The study’s survey of 357 Swiss secondary school teachers reveals significant positive correlations between will, skill, and tool variables and the combined frequency and diversity of technology use in teaching. A multiple linear regression model was used to identify relevant subfactors. Five factors account for a total of 60% of the explained variance in the intensity of classroom ICT use. Computer and Internet applications are more often used by teachers in the classroom when: (1) teachers consider themselves to be more competent in using ICT for teaching; (2) more computers are readily available; (3) the teacher is a form teacher and responsible for the class; (4) the teacher is more convinced that computers improve student learning; and (5) the teacher more often employs constructivist forms of teaching and learning. The impact of constructivist teaching was small, however.  相似文献

The study addressed two limitations of previous research on factors related to teachers’ integration of technology in their teaching. It attempted to test a structural equation model (SEM) of the relationships among a set of variables influencing preservice teachers’ use of technology specifically to support student-centered learning. A review of literature led to a path model that provided the design and analysis for the study, which involved 206 preservice teachers in the United States. The results show that the proposed model had a moderate fit to the observed data, and a more parsimonious model was found to have a better fit. In addition, preservice teachers’ self-efficacy of teaching with technology had the strongest influence on technology use, which was mediated by their perceived value of teaching and learning with technology. School’s contextual factors had moderate influence on technology use. Moreover, the effect of preservice teachers’ training on student-centered technology use was mediated by both perceived value and self-efficacy of technology. The implications for teacher preparation include close collaboration between teacher education program and field experience, focusing on specific technology uses.  相似文献

Research has shown that will (positive attitudes), skill (technology competency), and tool (access to technology tools) are all essential ingredients for a teacher to effectively integrate information technology into classroom practices. This study focuses on the will, skill and tool as essential measures for the predictability of technology integration, reported by the study participants and measured by stages of adoption of teachers in Ghana. Attempts are made to explore the extent to which these parameters differ among the teachers and also influence technology integration. Furthermore, the parameters are proposed for use in modelling the process of technology integration for these teachers. Well validated instruments spanning the areas of attitudes, competencies, access and technology integration proficiencies were used to collect data from 120 mathematics prospective teachers and 60 practicing mathematics teachers from Ghana. The data was analyzed using regression analysis. The results indicated that lack of teacher anxiety was the most important dimension of attitudes, and that skill is the strongest predictor of classroom integration of technology for the teachers. Significant differences existed between practicing and prospective teachers’ computer anxieties, competencies, and access levels.  相似文献

This study discusses the pedagogical potential of an interactive voting system used in conjunction with interactive whiteboard technology. The data discussed here are drawn from a qualitative study, carried out in the context of a British university pre-sessional programme in English for Academic Purposes and Study Skills for international students in the summers of 2003 and 2004. Research data were collected via a variety of ethnographic research instruments, namely classroom observations and feedback from critical colleagues, teacher’s field notes, video recording of classes, semi-structured interviews with students, and pre- and post-course student questionnaires. The findings indicate that the electronic voting system was seen to increase considerably the scope of interactivity during the lessons by helping students to enhance their development into active participants. However, the data have also indicated that the levels of interactivity in the approaches adopted in the context investigated could still be considered relatively “shallow”, and some suggestions have been provided to improve this aspect of technology use.  相似文献

This paper analyses the process of multimedia integration in English language classrooms equipped with interactive whiteboard (IWB) technology, and offers insights into the theoretical underpinnings of multimedia use in language learning from the perspective of cognitive learning theory. The data discussed here are drawn from a study carried out as part of a PhD research programme at Lancaster University (UK). The study was conducted within an interpretative research paradigm, and data were collected and analysed according to a qualitative approach. In the first part, the paper discusses some perceived pedagogical benefits of adopting a multimedia-oriented approach in the IWB-based classroom. Secondly, it discusses a variety of potential problems related to the use of multimedia resources in the language classroom in question. Finally, the paper draws upon the literature on multimedia learning to address the potential pedagogical implications of these research findings.  相似文献

ICT & learning in Chilean schools: Lessons learned   总被引:1,自引:0,他引:1  
By the early nineties a Chilean network on computers and education for public schools had emerged. There were both high expectancies that technology could revolutionize education as well as divergent voices that doubted the real impact of technology on learning. This paper presents an evaluation of the Enlaces network, a national Information and Communication Technologies (ICTs) and education initiative designed as part of a series of programs to overcome inequity and quality issues of public education in Chile, by integrating teachers and learners into the knowledge society. Data gathered and the results obtained in four major areas of educational policies – infrastructure, digital literacy, conditions of learning, and the impact on school learning of major national and international tests – are presented and fully analyzed. The strengths and weaknesses of Enlaces as a visible component of the educational system and educational reform are also discussed. Enlaces has provided basic infrastructure tools, connectivity, ICTs, and teacher training to a huge number of schools, but critical results are narrow in terms of classroom learning and no additional competencies have been observed. Data and results are limited by structural bottlenecks in the educational and social system. Finally, the lessons learned after more than 15 years of implementing technology in Chilean schools are presented and fully discussed.  相似文献

The increased access to, but continued under-use of, technology in education makes it imperative to understand the barriers teachers face when integrating technology into their classrooms. While prior research suggests teachers encounter both first-order extrinsic barriers and second-order personal barriers, much of this research has focused on K-12 teachers, not early childhood educators. Applying the Unified Theory of Acceptance and Use of Technology to early childhood education, the current study examines predictors of early childhood educators' access to and use of traditional technologies and newer mobile devices. Findings from 1329 teachers of 0–4-year-olds reveal that while extrinsic barriers influence access to a range of technologies, positive beliefs in children's learning from technology significantly predicted actual use of technology. Overall, the study provides new insight into factors influencing technology integration specifically for early childhood educators, a subgroup that has not been represented in much of the literature on technology integration in formal education.  相似文献

In this study we use a model which we refer to as the ‘teacher–technology environment interaction model’ to explore the issue of the stress experienced by teachers whilst using ICT in the classroom. The methodology we used involved a comparison of three datasets obtained from: direct observation and video-logging of the teachers in the classroom; recordings of their galvanic skin response (GSR) taken whilst teaching; and interviews. Data were obtained from nine teachers, and in total, approximately 32 h of teaching activities were observed. The main results of this study were (a) the demonstration that teachers do suffer stress associated with the use of technology in the classroom (i.e. technostress) (b) the identification of causes, symptoms and coping strategies associated with technostress in the classroom. This study, therefore, points to an alternative way of thinking about the problems of implementing e-learning by conceptualizing some of these implementation problems in terms of technostress (and in particular of teacher–technology environment fit).  相似文献

This study explored how teacher variations in use of a web-technology of known effectiveness, affected growth in literacy. Teachers used ABRACADACABRA (ABRA) (http://grover.concordia.ca/abra/version1/abracadabra.html), in Grade 1 Language Arts classes. Children (N = 60) across three classrooms were exposed to ABRA activities and a control class followed the regular provincial literacy program. Interventions were run by briefly-trained teachers for a total of 16 h. Each teacher chose to use the program in qualitatively distinct ways that corresponded to the first three stages of Sandholtz, Ringstaff, and Dwyer’s (1997) technology integration model, namely: Entry, Adoption and Adaptation. Growth in literacy between pre- and post-test revealed significant differences associated with technology integration style across all measures of literacy and related language skills. The largest and most-widespread effects were evident for the Adaptation group that linked technology content to wider learning themes in the classroom. In terms of overall growth in standardised literacy scores across all six such measures used, Adaptation proved to be 60% more effective than Adoption. Results suggest that explorations of exactly how teachers use technology have important implications for practice as well as for the interpretation of field-based studies of the effectiveness of educational technology.  相似文献

A meta-analysis was performed to synthesize existing research comparing the effects of computer-assisted instruction (CAI) versus traditional instruction (TI) on students’ achievement in Taiwan. Fifty-two studies were located from four sources, and their quantitative data was transformed into effect size (ES). The overall grand mean of the study-weighted ES for all 52 studies was 0.55. The results suggest that CAI is more effective than TI in Taiwan. In addition, two of the seventeen variables selected for this study (i.e., statistical power, and comparison group) had a statistically significant impact on the mean ES.  相似文献

University classes in Mathematics are traditionally perceived to be uninspiring and devoid of active student–lecturer communication. Large undergraduate classes further compound the difficulty of engaging students and enabling viable student–lecturer feedback. At the Mathematics Education Centre, Loughborough University, some staff members have been using electronic voting systems (EVS) to enliven the classroom and enable large numbers of students to respond to questions in real time during class. In this paper, we present an evaluation case study, based on student perceptions, of the impact of EVS use on student learning and engagement. The results show that majority of students are hugely positive about the usefulness and overall advantageousness of EVS use in classes. Results also show that EVS use does increase the likelihood of students participating and engaging in class, as even students who do not view EVS as being particularly useful stated that they are more likely to participate in classes where EVS are used than otherwise. However, there seems to be no correlation between EVS use and improvement (or otherwise) in student grades.  相似文献

Many lecture halls today have two or more screens to be used by instructors for lectures with computer-supported visual aids. Typically, this additional screen real estate is not used to display additional information; rather a single stream of information is projected on all screens. We describe a controlled laboratory study that empirically assesses the effect on students learning of using the increased classroom screen real estate to project an additional stream of information. We measured how well participants learned from a two-stream presentation compared to a one-stream presentation duplicated on both screens. Data indicate that using extra screen real estate can indeed improve learning. In particular, learning was most improved when pertinent prior information was shown alongside currently explained information. There is also evidence that visual comparisons were improved with parallel viewing using extra screen real estate. Subjective data gathered from participants showed a strong preference for learning with two streams of content over a regular one-stream presentation.  相似文献

With the goal of promoting student–teachers to reflect on their teaching performance, a web-enabled video system was developed to permit them to record their classroom performance and then retrieve online videos of their teaching for self-reflection. This study aimed to evaluate the effectiveness of online videos in facilitating self-reflection amongst student–teachers. Eight student–teachers from four disciplines were invited to use the video system to reflect on their teaching in two lessons. A content analysis was conducted to compare the reflective notes made by the student–teachers before and after browsing the videos of their teaching. The results indicated that video browsing prompted student–teachers to generate an additional 50 per cent of reflective notes and stimulated them to significantly increase the depth of their reflective thoughts in the areas of discipline and classroom management, and professional knowledge on teaching. Building on the gains achieved in this way, student–teachers can subsequently engage in in-depth professional dialogue with their teacher supervisors.  相似文献

The pace of technology adoption by university faculty is often slow. Slow faculty technology adoption may result from fear of failure, disinterest, or aversion to change. However, in 2007 we experienced a different faculty response while training faculty for technology-enhanced teaching at Butler University. During a technology upgrade of classrooms on our campus, we installed SMART interactive whiteboards and Sympodiums (SMART Technologies), visual presenters and CopyCams (Polyvision/Steelcase). The technology trainers and information technology (IT) department anticipated a lack of faculty interest in training on these technologies. It was posited that faculty would not be interested in learning about these interactive and presentation technologies unless this learning could be connected in some way to their individual teaching interests and responsibilities. A novel, collaborative training model was developed to achieve this goal of placing technology training into a pedagogical context. A multidisciplinary group of faculty, working closely with representatives from IR, served as trainers for this highly successful faculty development effort in which 27% of the university faculty were trained over a three month period. This article details the methods and outcomes of this collaborative training team approach.  相似文献

This paper investigates the use of ICT by teachers in selected secondary schools. It considers both the extent and type of use and the factors that may influence such use through the statistical analysis of data from a 30-section survey containing 185 items. First, exploratory maximum-likelihood factor analysis was used to identify five distinct categories, or types of use. Second, path analyses assisted in determining ten antecedent factors which significantly impacted on use from a total of 16 factors considered. These factors were confirmed using scale analyses. Finally, a multivariate analysis of variance (MANOVA) was used to determine whether demographic/context variables were related both to use and to those factors directly influencing usage. Findings suggest a variety of types of professional development, as well as a range of infrastructural options, are needed to meet not only the varying needs of individual teachers, but also the varying ways in which ICT can be used. The implication is that the key outcomes for any professional development must be to increase teacher confidence in their ability to facilitate student learning with computers, along with the provision of stronger pedagogical motivation for teachers to integrate ICT.  相似文献

To investigate the benefits and perceived effectiveness of instructional technology, students enrolled in several courses were compared on student evaluations of instruction, grades and an attitudinal questionnaire. The instructors of the courses taught the same course across two successive semesters, using traditional “chalk-and-talk” methods the first semester, and PowerPoint the next; all other techniques (e.g., exams, lecture material) were held constant. Results suggest that organization and clarity, entertainment and interest, professor likeability, and good professor behaviors were enhanced with PowerPoint although final grades were not.  相似文献
