Developing and validating science education videodiscs

The development of videodiscs for science instruction in public schools requires a recognition of the unique characteristics of the public school environment and a sensitivity to the persistent problems associated with science instruction. This report discusses the conceptualization, development, and formative evaluation of a series of science education videodiscs. The discs were designed to enhance the efforts of teachers working in both individual and group instructional settings. In presenting the content, particular attention was given to the “effective instruction” research literature and more subject-matter–specific problems such as those associated with the use of terminology and the fragmentation of information. The formative data indicated that videodisc programs can enhance the effectiveness of teachers and substantively impact student achievement and attitudes.     

Response Inhibition,Memory, and Attention in Boys with Attention-Deficit/Hyperactivity Disorder

Newly developed measures of response inhibition, verbal and non-verbal memory, and attention were applied to a sample of boys diagnosed with ADHD (n = 50; 14 predominantly inattentive type and 36 combined type) with no diagnosed comorbid conditions, who had received no stimulant medication for a minimum period of 20 hours prior to test administration. Performance was assessed relative to 50 individually age-matched control boys. Results revealed significant multivariate group differences on all three tests, supported by univariate effects on measures of verbal memory and attentional switching. In all cases, ADHD boys performed more poorly than the control boys. However, contrary to expectations, boys with ADHD made significantly fewer impulsive responses (false positives) on the specific measure of response, despite recording significantly more misses than the controls. Furthermore, no significant differences were observed according to ADHD subtype. The present research therefore demonstrates and more fully characterises the nature of the observed memory and attentional impairments in boys with ADHD and would appear to have clear implications for education and the further development of theory.     

Including Pupils with Special Educational Needs and Disability in National Assessment: Comparison of Three Country Case Studies through an Inclusive Assessment Framework

The assessment of educational progress and outcomes of pupils is important to all concerned with education. This includes testing which is undertaken for accountability and award bearing purposes. This article examines how students with special educational needs and disability (SEND) are included in assessment. An “inclusive assessment” framework is outlined based around three core features: (1) all students are included and benefit from assessment; (2) assessments are accessible and appropriate for the diverse range of children in the education system; and (3) the full breadth of the curriculum is assessed (including curriculum areas of particular relevance to students with SEND). Assessment policies and practice in three countries (England, Ireland and the US) are drawn upon to demonstrate how the framework usefully enables between-country comparisons and within-country analysis. This analysis shows that in comparison to Ireland, the US and England have highly developed system-based approaches to assessment which seek to “include all” (feature 1) and be “accessible and appropriate” (feature 2). However, the analysis highlights that a consequence of such assessment approaches is the narrowing of the curriculum around topics that are assessed (most notably literacy and mathematics). Such approaches therefore may be at the expense of wider curriculum areas that have value for all students, but often of particular value for those with SEND (feature 3). It is argued that within such systems there may be a danger of neglecting the third feature of the inclusive assessment framework, i.e. ensuring that the full breadth of the curriculum is assessed. A consequence of such an omission could be a failure to assess and celebrate progress in relation to educational outcomes that are relevant to a diverse range of students.     

The Structure and Coherence of Competence from Childhood through Adolescence

The structure and coherence of competence from childhood (ages 8–12) to late adolescence (ages 17–23) was examined in a longitudinal study of 191 children. Structural equation modeling was utilized to test a conceptual model and alternative models. Results suggest that competence has at least 3 distinct dimensions in childhood and 5 in adolescence. These dimensions reflect developmental tasks related to academic achievement, social competence, and conduct important at both age levels in U.S. society, and the additional tasks of romantic and job competence in adolescence. As hypothesized, rule-breaking versus rule-abiding conduct showed strong continuity over time, while academic achievement and social competence showed moderate continuity. Results also were consistent with the hypothesis that antisocial behavior undermines academic attainment and job competence.     

A classroom observational study of Qatar's independent schools: Instruction and school reform

Qatar initiated a K–12 national educational reform in 2001. However, there is limited information on the instructional practices of the teachers in the reform schools. This project was an observational study of classrooms with a stratified random sample of the first six cohorts of reform schools. Specifically, 156 classrooms were observed in 29 reform schools. Instructional differences were noted in schools with different gender of students and were moderated by school level. Implications of findings were discussed pertaining to implementation of the Qatar national reform and professional development needs of teachers.     

Objectivity of boys with attention-deficit/hyperactivity disorder (adhd) and their mothers when responding to a caricatured portrayal of adhd

In a recent theoretical model of Attention-Deficit/Hyperactivity Disorder (ADHD) it is proposed that a core deficit in response inhibition affects, among other things, an individual's objectivity in their reaction to events. In the context of this, the ability of boys diagnosed with ADHD objectively to differentiate their own behaviour from that of a caricatured portrayal of ADHD by Bart Simpson was examined. Four segments, each lasting 10–15 seconds, depicting ADHD related behaviours were isolated from a television episode of The Simpsons and shown in random order to 39 boys diagnosed with ADHD, their mothers, and two paediatricians. After watching each segment, the boys were asked to show how similar they believed their behaviours were to those exhibited by Bart Simpson by simultaneously placing two figures (one a replica of Bart and another representing themselves) on a chequer board. Mothers were subsequently administered the same procedure to indicate how they viewed their sons' behaviour in relation to Bart's. The distance measured between the two figures was representative of their levels of objectivity compared to a benchmark level set by the two paediatricians using the same chequer board procedure. While the results overall indicate that boys with ADHD and their mothers are able to make distinctions between caricatured and typical ADHD behaviours, the results are mediated by both ADHD subtype and the specific ADHD behaviour portrayed in the video segment.     

Identifying paralogisms in two ethnically different contexts at university level / Identificación de paralogismos en dos contextos universitarios diferenciados étnicamente

Abstract

Although educational researchers have long tried to answer the question ‘Who reasons well?’, little has been done in regards to the influence of culture on argumentative reasoning quality. Among the factors that have been related with the construction of valid arguments, counterarguments and rebuttals by adults are: explicit argument training, task instructions and prior knowledge. No clear evidence exists regarding the influence of the ethnical background on the flaws or fallacies of reasoning. The present study applies the recent theory of paraschemes as a tool to identify university students’ paralogisms in a common argument-mapping task on everyday issues in two different cultural contexts: one European (Spain) and one Middle Eastern (United Arab Emirates). Our analysis showed that the influence of ethnical background was not statistically significant regarding the type and amount of paralogisms committed. On the contrary, the participants’ study major, being business or education, was shown to influence the production of argument fallacies. Implications of these findings for higher education are discussed.     

Appropriation, Appreciation, Accommodation: Indigenous Wisdoms and Knowledges in Higher Education

This paper focuses on differences between the underlying principles of Western science and the knowledges and wisdoms of Indigenous peoples in such places as Australia, Southeast Asia, Africa, and Central and South America. It notes changing phases in the approaches to Indigenous Wisdoms and knowledges, and highlights the shifts from appropriation to appreciation and then accommodation. Nevertheless, major tensions remain, both within and between Western science and Indigenous knowledges and appreciations. This creates challenges for institutions of higher education, as well as for other bodies.     

Instructor influence on reasoned argument in discussion boards

In this study, we explore the extent to which two instructional techniques promote critical discourse in an online class on educational standards and curriculum: instructor stance (challenging/nonchallenging) and topic level (higher order/lower order). Posts from 25 students, across four modules, were analyzed. These four modules constituted approximately one third of the course, and were selected because the professor was the sole facilitator for them. Results indicate that, regardless of topic level, a challenging stance by the professor had a positive effect on the percentage of student posts that referenced readings and theory. There was an interaction between level and stance on student use of reasoned argument. Lower order challenging forums were associated with a greater percentage of reasoned posts. This may be due to the abstractness of the professor's probes in higher order forums. Implications for future research include empirical investigations incorporating contextual variables and qualitative studies to ascertain how students engage with bulletin boards.     

Environmental,cognitive, and metacognitive influences on text revision: Assessing the evidence

To assess progress in understanding text revision, we review research reported since 1980, when process analyses of writing were beginning (Fitzgerald, 1987). A modernized version of the revision model by Flower, Hayes, Carey, Schriver, and Stratman (1986) was used to organize findings about how revision is influenced by environmentally posed rhetorical problems and actual text variables; by cognitive knowledge, strategies, and representations of the text being revised; by metacognitive understanding, monitoring, and control of knowledge and strategies; by interactions among these environmental, cognitive, and metacognitive influences; and by how working memory limits those interactive influences. These influences have been studied with a rich diversity of research approaches, and even though no part of the modernized model has been studied fully, and even though interactions of the model's parts have been examined minimally, clearly interpretable results have been reported about all of the model's parts. Substantial and encouraging progress has been made toward understanding text revision, and the stage has been set for more progress. We suggest investigations to increase understanding of revision and to promote integration of research and theory about reading and writing.
