Learner Characteristics that Influence the Treatment Effectiveness of Early Literacy Interventions: A Meta‐Analytic Review     

J. Ron Nelson  Gregory J. Benner  Jorge Gonzalez 《Learning disabilities research & practice》2003,18(4):255-267

The purpose of this article was to systematically review the available research on learner characteristics that influence the treatment effectiveness of early literacy interventions. Meta‐analytic procedures were applied to a total of 30 studies that met the inclusionary and exclusionary criteria. Mean average effect sizes were computed for seven primary learner characteristic categories: (1) rapid naming, (2) alphabetic principle, (3) phonological awareness, (4) problem behavior, (5) memory, (6) IQ, and (7) demographic. The primary learner characteristics that influenced the treatment responsiveness of early literacy interventions were, in order of magnitude, rapid naming, problem behavior, phonological awareness, alphabetic principle, memory, IQ, and demographics. With the exception of the demographic category, the obtained effect sizes for the primary learner characteristics were moderately large. The demographic primary learner characteristic (i.e., disability, ethnicity, grade‐level status) of children was not statistically (p < 0.05) distinct from zero. The findings, limitations, and future research needs are discussed.  相似文献   

Environmentally-induced stone decay: the cumulative effects of crystallization–hydration cycles on a Lincolnshire oopelsparite limestone     

Belinda J. Colston  David S. Watt  Helen L. Munro   《Journal of Cultural Heritage》2001,2(4)

An investigation has been undertaken at St Andrew’s church, Walpole St Andrew, Norfolk, to establish the underlying causes of the observed stone decay to the upper parts of the six stone piers. The stone decay was first recorded in the early 1930s. The salt-contaminated masonry within the church has been shown to undergo severe salt decay during the summer, with little damage occurring over the winter months. The south aisle piers have been shown to decay 2.5 times faster than the north aisle piers. Although crystallization–hydration cycles have been identified, the rate of decay is at its greatest when the cycling is relatively infrequent. This was not the expected trend. Furthermore, it has been shown that during extended periods where the ambient relative humidity is less than 75%, the rate of decay reaches a maximum. It is the length of this ‘drying’ period that apparently has the greatest influence on the rate of decay and could explain the significant difference in the rate of decay between the south and north aisle piers. The results have serious implications for passive conservation, where it is often recommended to lower the ambient relative humidity to well below the equilibrium relative humidity of the salt contaminant, to avoid crystallization–hydration cycles. Since, at the time of building, the church was situated on the coast, it is possible that the sodium chloride contamination occurred during the building process (1440–1520), particularly since the area was prone to sea-flooding at this time. Alternatively, the salt could have been applied as a treatment during the general restoration of 1897. Whatever the source of the salt, it seems likely that the ambient environment was changed by the insertion of a sealed floor in 1897, which could account for the onset of the salt decay.  相似文献

University Admissions and the Prediction of Degree Performance: an Analysis in the Light of Changes to the English Schools’ Examination System     

Ron Johnston  David Manley  Kelvyn Jones  Richard Harris  Anthony Hoare 《Higher Education Quarterly》2016,70(1):24-42

The United Kingdom's Department for Education has recently changed the nature of the AS‐level examinations normally taken by students aspiring to enter higher education degree courses one year into their post‐compulsory education. In the face of protests from universities and other institutions that this would both harm students’ progression towards the A‐level qualifications, on which entry to English universities is normally based, and make it difficult for universities determining which of their applicants were best placed to benefit from their degree courses, the Department conducted research which it claimed showed that degree outcome could be predicted as well from the results of GCSE examinations taken one year before AS‐levels as from AS‐levels themselves. This paper critiques those analyses and their conclusions showing, through a re‐analysis and extended interpretation of the Department's data, that AS‐levels provide a more reliable predictor of degree performance in 2011 than GCSEs and that many students who performed better at AS‐level than at GCSE gained a place, and performed well, at a university with high entrance standards.  相似文献   

Change management and the SENCo role: developing key performance indicators in the strategic development of inclusivity     

Liz Done  Mike Murphy  Mia Watt 《Support for Learning》2016,31(4):281-295

This article follows an earlier publication highlighting the changing role of special educational needs co‐ordinators (SENCos) in England. SENCos are now required to manage change strategically and deliver inclusive school cultures. School‐based action research undertaken by a teacher studying for the postgraduate National Award for SEN Co‐ordination (NASENCO) is featured in the article; a strategic review of resource allocation increased the availability and quality of interventions for students with special educational needs and disabilities (SEND). The commentary which frames the study acknowledges that many SENCos are not yet members of a senior school management team (SMT) despite their mandated strategic whole‐school remit. Featuring the process through which one SENCo has strived to enhance SEND provision and develop context‐specific key performance indicators brings official guidance on the SENCo's role in strategic change management into sharp focus, raising questions that should concern both SMTs and non‐SMT SENCos.  相似文献

The differential effects of prior knowledge on learning: A study of two consecutive courses in earth sciences     

Ron Hoz  Dan Bowman  Ely Kozminsky 《Instructional Science》2001,29(3):187-211

We studied the occurrence and nature of learningin a university first year Introduction toGeomorphology course, and its relations with priorknowledge taught in a prerequisite course, and withthe prior knowledge in the to be learned subjects. Tendimensions of knowledge were tapped before and afterthe course by conventional and cognitive structuremeasures that were derived by the concept mappingmethodology. The fine-grain analysis of learningoutcomes yielded the following results: (a) studentsacquired only a small portion of the content in thecourse Introduction to Geomorphology, (b) the priorgeological and geomorphological knowledge did notaffect the learning of the new geomorphologicalcontents, (c) the minor effects appeared within ratherthan across knowledge dimensions, and they affectedmainly the learning of smaller knowledge units, and(d) concept definition cannot be considereda valid probe of knowledge. The differential effects of prior knowledge question thecentral, global and undifferentiated role that schematheories ascribe to prior knowledge in futurelearning. They call for greater reference to theexposed dimensions of knowledge by suggestingadditional factors to be considered in the sequencingof courses, as well as to the acquisition of complexknowledge with partial meaning of the basic knowledgeunits, and the use of new cognitive structure probesof knowledge.  相似文献
