Because multimedia computer programs may provide promising opportunities for the training of initial reading and spelling skills, two small‐scale pilot studies have been conducted with a recently‐developed program to examine its efficacy and impact on the motivation of the users. The first study is concerned with the use of the program in kindergarten children (K2). As there is no curriculum for these children, a computer program that is fully adaptive may well boost their independence in learning to read and spell. The main finding in this study was that kindergarten readers learned in up to 16 hours of computer practice as much as is normally attained in the first 3 months of formal reading instruction in the classroom. In the second study, reading‐disabled students with low levels of motivation engaged in computer‐based spelling practice. The most important finding in this study was that the amount of non‐task directed behaviour of those who had practised with the computer significantly decreased during both computer sessions and classroom sessions. In the discussion the way in which computers can be used most efficiently for the instruction of reading and spelling is analysed and suggestions for further research and development are presented.  相似文献

This investigation examined early childhood teachers' attitudes towards families and their involvement with schools, and specific variables that influence these attitudes. Teachers' perspectives about school and family partnerships were assessed using the School and Family Partnerships: Questionnaires for Teachers and Parents in the Elementary and Middle Grades (Epstein & Salinas, 1993). This survey was administered to 92 elementary school teachers in Follow Through classrooms in the southeastern and pacific northwestern United States. Results indicated that teachers' attitudes about family and community involvement were highly positive. Additionally, African American teachers had a more positive attitude than European American teachers. Furthermore, teachers who taught large proportions of low ability students had less positive views of family strengths.  相似文献

Two algorithms are provided which define two new ways of averaging waveforms. The representative average maintains shape, has average d.c. offset, average amplitude and average position of noise-free input signals whose onset varies in time after a trigger pulse. The synchronous average removes random bipolar noise, the amplitude of which is below a critical threshhold, from a randomly occuring waveform. The latter does not require a trigger pulse, maintains its shape, has an average d.c. offset and average amplitude. Its position in the output field is such that the centroid of the waveform is placed in the center of the field. Both methods involve the definition of average phase angle and a quantity called the angular standard deviation.  相似文献

Over the past two decades, both developed and developing countries have been investing a significant portion of their resources in the creation of an information infrastructure. However, speculation abounds regarding the efficacy of information infrastructure investments, especially when the opportunity cost for investing in information technology (IT) is measurably high among developing nations. This longitudinal study introduces and explores infrastructure development and service-sector growth as key metrics for IT investment success. It also traces the notional evidence of IT infrastructure development as mediating the causal relationship between information infrastructure investments and service-sector growth. Using data from low-income, middle-income, and high-income countries, the mediating and lagged impact of information infrastructure on service-sector growth reveals that information infrastructure development does play a significant role as a mediator. It points out that information infrastructure investments can be a misleading causal antecedent if countries fail to develop their infrastructure. It also provides evidence of a recursive relationship between infrastructure development and service-sector growth. An exploratory time-series analysis across different country categories suggests that information infrastructures must be properly developed to reconcile the paradox. In addition, exploratory tests reveal a distinct divergence between infrastructure investments and infrastructure development among different country tiers.  相似文献

The Cloud Computing Business Framework (CCBF) is proposed to help organisations achieve good Cloud design, deployment, migration and services. There are four key areas to be addressed: (i) Classification; (ii) Organisational Sustainability Modelling (OSM); (iii) Service Portability and (iv) Linkage. Each area's focus is described, and we explain how each fits into the CCBF and work altogether. The process that leads the CCBF is supported by literature, case studies, where examples in each CCBF key area are used to illustrate its effectiveness and contributions to organisations adopting it. CCBF has been used in several organisations offering added values and positive impacts.  相似文献

This study investigated the instructional preferences of full time adult credential students after they took a live course called Principles of Adult Education at California State University, Long Beach (CSULB) in the fall semester of 2002. These full time adult credential students had been working on their adult teaching credentials to meet the competencies specified by the California Commission on Teacher Credentialing. The course introduced students to Andragogy developed by Malcolm Knowles out of the andragogical model developed by Lindeman (1926). The study used Principles of Adult Learning Scales (PALS), advanced by Gary Conti in 1983 to measure instructional preferences. Data were collected from 30 (100% of 30) full time adult credential students enrolled in a live course to determine their instructional preferences of helping adults learn. The results of the study showed in most cases these adult learning professionals taught adult students andragogically; in some cases they taught adult students pedagogically.  相似文献

The methods and conclusions of Van den Broeck (in this issue) are evaluated from two perspectives: (a) statistical considerations and (b) theoretical models of IQ and achievement, specifically reading achievement. We consider the statistical model proposed by Van den Broeck for the regression-based discrepancy model (RDM) to be either irrelevant or conceptually inconsistent with current models of IQ and achievement. The resulting simulation produced exemplar cases that are not realistic in terms of practice. The theoretical representations of IQ and achievement were, in our understanding, inconsistent with contemporary models of either. We suggest that acceptable models support the use of the RDM as it has been proposed by us and by others as one component of the determination of the presence or absence of a learning disability.  相似文献
