James Scott Johnston 《Educational theory》2016,66(6):719-734
In this essay, James Scott Johnston examines Jürgen Habermas's transcendental justification of his discourse theory of morality. According to Johnston, the application of Habermas's theory to educational issues often assumes that this justification is a cogent one. However, if the theory is to provide reasoned and appropriate guidance for educators, the justification of discourse ethics requires closer examination. Johnston argues that Habermas's so‐called “weak” transcendental approach is in fact unsustainable because it fails to reconcile two conflicting schools of philosophical thought: Kant's transcendental idealism and George Herbert Mead's social pragmatism. Johnston concludes that a more plausible justification of the discourse ethical project can be achieved by rejecting Habermas's Kantianism and appealing solely to Mead's social pragmatic conception of rationality. 相似文献

A sample of college-bound juniors from 275 high schools took a test consisting of 70 math questions from the SAT. A random half of the sample was allowed to use calculators on the test. Both genders and three ethnic groups (White, African American, and Asian American) benefitted about equally from being allowed to use calculators; Latinos benefitted slightly more than the other groups. Students who routinely used calculators on classroom mathematics tests were relatively advantaged on the calculator test. Test speededness was about the same whether or not students used calculators. Calculator effects on individual items ranged from positive through neutral to negative and could either increase or decrease the validity of an item as a measure of mathematical reasoning skills. Calculator effects could be either present or absent in both difficult and easy items 相似文献

The term “creativity” can conjure various ideas and meanings. It's no surprise that methods for measuring such a concept vary widely and are not without controversy. This is particularly true among people with autism spectrum disorder (ASD), who are a unique yet incredibly diverse group of individuals. This article provides an overview of the assessment of creativity among individuals with ASD. Findings among studies that have sought to determine whether individuals with ASD are more or less creative than their neurotypical peers are mixed, yet the authors propose that intentional development of creativity in all youth, including those with ASD, can be beneficial. 相似文献

This article discusses the growing consensus across diverse educational research domains that the historical aspects of cognition are important for understanding not only how individuals but also disciplines know what they know. After proposing and defining the new superordinate concept of historicality, fundamental interrelationships between time, events, memory, meaning, personal knowledge, public knowledge, and the histories of the sciences are explored. Relevant research findings that demonstrate the confluence of scholarly thought concerning historicality across five educationally important domains are presented for the reader's consideration. Using the historicality concept, it is suggested that the histories of the sciences be considered as “the collective mind of scientists” and viewed as vital to developing students' knowledge about science by building upon the critical distinctions drawn by Duschl (1990). The author's science teaching technique, based upon construction of historical vignettes, is introduced here because of the relationship between history and story and the documented educational effectiveness of the story format. Finally, the author adds several cautionary notes about the validity of explanations based upon historicality and anticipates future advances in our understanding of the historicality of cognition. 相似文献

On the validity and sensitivity of the phonics screening check: erratum and further analysis 下载免费PDF全文
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 ).
- 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.
- 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.

As low-stakes testing contexts increase, low test-taking effort may serve as a serious validity threat. One common solution to this problem is to identify noneffortful responses and treat them as missing during parameter estimation via the effort-moderated item response theory (EM-IRT) model. Although this model has been shown to outperform traditional IRT models (e.g., two-parameter logistic [2PL]) in parameter estimation under simulated conditions, prior research has failed to examine its performance under violations to the model’s assumptions. Therefore, the objective of this simulation study was to examine item and mean ability parameter recovery when violating the assumptions that noneffortful responding occurs randomly (Assumption 1) and is unrelated to the underlying ability of examinees (Assumption 2). Results demonstrated that, across conditions, the EM-IRT model provided robust item parameter estimates to violations of Assumption 1. However, bias values greater than 0.20 SDs were observed for the EM-IRT model when violating Assumption 2; nonetheless, these values were still lower than the 2PL model. In terms of mean ability estimates, model results indicated equal performance between the EM-IRT and 2PL models across conditions. Across both models, mean ability estimates were found to be biased by more than 0.25 SDs when violating Assumption 2. However, our accompanying empirical study suggested that this biasing occurred under extreme conditions that may not be present in some operational settings. Overall, these results suggest that the EM-IRT model provides superior item and equal mean ability parameter estimates in the presence of model violations under realistic conditions when compared with the 2PL model. 相似文献

Current federal government policy initiatives in Aboriginal education and social welfare reform are based on assumptions about the relationship between increased attendance and increased student performance on standardized tests. There are empirical assumptions underlying these policy interventions and their accompanying public debates. Our aim here is to empirically explore the relationships between patterns of student attendance and patterns of student achievement in schools with significant cohorts of Aboriginal and/or Torres Strait Islander students at the school level. Based on an analysis of the publicly available data reported on the ‘MySchool’ website, we find that reforms and policies around attendance have not and are unlikely to generate patterns of improved achievement. Questions about the rationale and rhetoric of government policy focused at the school level as opposed to the need to focus on pedagogy and curriculum are discussed. 相似文献
