Building electronic communities: success and failure in computer networking   总被引:7,自引:0,他引:7  
This paper is about networking failures as well as networking successes. A research strategy for comparing educational activities conducted across electronic networks was employed to examine the critical features of successes as well as failures in designing electronic communities. The analysis provides a set of guidelines for those who plan to use telecommunications as a tool for creating global communities.  相似文献

Duff, Mengoni, Bailey and Snowling (Journal of Research in Reading, 38: 109–123; 2015) evaluated the sensitivity and specificity of the phonics screening check against two reference standards. This report aims to correct a minor data error in the original article and to present further analysis of the data. The methods used are calculation of predictive values of the phonics screening check in addition to sensitivity and specificity, and evaluation of agreement between the reference tests. Predictive values are important indicators of screening test quality. The positive predictive value of the phonics check is low (0.31) when compared with a standardised reading test but high (0.84) when compared with teachers' phonic phases judgements, reflecting poor agreement (kappa = 0.27) between reference tests. Results have implications for practice in terms of choice of reference standard and choice of threshold criterion for children to pass the screening check. Longitudinal data are needed to assess the predictive validity and utility of the check. What is already known about this topic:
  • The importance of phonics in learning to read is widely acknowledged.
  • The phonics screening check was introduced into U.K. schools in 2012 to ensure that all children develop phonic decoding skills.
  • Estimates of the sensitivity and specificity of the phonics screening check, compared with two established ‘reference’ measures, were reported by Duff et al. ( 2015 ).
What this paper adds:
  • We correct a minor error in the report of the original data by Duff et al. ( 2015 ).
  • We draw attention to the importance of including predictive values, alongside sensitivity and specificity, in the evaluation of screening test validity. We also propose an alternative statistic for comparing the two reference measures.
  • We show that applying this further analysis to the data in Duff et al. ( 2015 ) reveals the following: (i) the numbers of incorrect (false positive and false negative) outcomes in the phonics check and (ii) the marked difference in these numbers depending on the choice of reference measure.
Implications for theory, policy or practice:
  • Reports of screening test validity should include positive and negative predictive values.
  • A fundamental consideration for evaluating the validity of the phonics screening check is the choice of reference measure.
  • Longitudinal data are needed to assess the predictive validity and utility of the phonics check.

This article explores community (primary) school teacher education in the subject, English, at a Papua New Guinea (PNG) teachers' college as manifested in end‐of‐year English lessons in practicum rounds of pre‐service community school teachers. English is the official language overlaid on 700 indigenous languages in this country where reconstructionism informs policy decisions. Given this, the importance of success in English in schools is not to be underestimated. The research focuses on the implementation the knowledge, skills, strategies and materials acquired by pre‐service English teachers in a coastal province in PNG in the context of a number of public statements on educational policy and practice. It examines the impact of these as indicated in lesson plans and supervisors' reports.  相似文献

The US charter school movement is based upon the supposition that granting individual public schools increased autonomy from state and district rules and regulations in exchange for more accountability will foster the creation of innovative, effective and efficient schools. However, while state charter school laws free these schools from various state and district rules and regulations, the schools must still operate within the civil rights parameters legislated by federal statutes. Of particular import are federal laws that guarantee that children with disabilities receive a free appropriate public education. Project SEARCH, a 3 year qualitative study of special education in US charter schools revealed that there is a fundamental philosophical gap between the individualised, autonomous nature of charter schools and the highly regulated nature of special education. The philosophical gap is complicated by some charter schools' inability to amass the fiscal and human capacity needed to meet the needs of individual children with disabilities.  相似文献

In this study, the authors examine the impact of a yearlong supplemental reading course involving daily instruction in the learning strategies curriculum on lower achieving adolescent students' reading achievement and motivation. Using a multiple-cohort randomized treatment-control group design over 4 years, they compared achievement and motivation outcomes for 605 sixth-grade students who participated in the intervention with 530 students who did not participate and 593 ninth-grade students who participated in the intervention with 535 students who did not participate. Results indicated significant impacts of the intervention on reading achievement for ninth-grade students but not for sixth-grade students. Significant impacts on reading motivation were found for both sixth- and ninth-grade students. An exploratory follow-up study indicated potential benefits of a second year of intervention for sixth-grade students who are still low achieving after 1 year of intervention.  相似文献

Higher education (HE) is regarded as a pathway to upward social mobility for those from lower socio-economic backgrounds. Social mobility is itself seen as important both for individual and national prosperity and is a key driver of government funding for HE. While access to HE has substantially increased over the past number of years, the evidence suggests that social inequalities continue to be reproduced, with working-class students more frequently accessing lower status institutions and courses. This in turn can impact negatively on their labour market outcomes. This paper offers a critical appraisal on the employability discourse. Drawing on a survey of 268 distance graduates from an Irish university, together with 5 individual interviews, findings indicate that distance graduates are likely to be from lower socio-economic backgrounds and have delayed participation in university education for reasons relating to social class. Although mostly in employment, they are motivated to participate in HE by their concerns regarding their long-term employability. The literature identifies that our employability is something we negotiate with others. This paper posits that, for distance graduates, in addition to this process of convincing others, the graduate must also convince themselves of the value of their own achievement. Transitioning to graduate employment, and developing a graduate identity, can therefore be a slow internal and external process of negotiation.  相似文献
