Teaching Teachers About Energy: Lessons from an Inquiry-Based Workshop for K-8 Teachers

We report results and impressions from a three-day inquiry-based workshop for K-8 teachers, aimed at improving their understanding of energy from a science and engineering perspective. Results suggest that the teachers made significant gains in understanding and appreciation of important energy concepts, but their comprehension of some key ideas remained incomplete. The dissipation of energy into thermal energy of the environment proved to be a particularly difficult idea, and one that represents a serious obstacle to understanding the principle of the conservation of energy.     

Educating World Teachers for Cosmopolitan Classrooms and Schools

This essay responds to the question of what it might mean to educate “world teachers” for cosmopolitan classrooms and schools through an examination of an ethnographic play entitled Satellite Kids. The author begins with the idea that teachers need to develop or build up “intercultural capital”, that is, knowledge and dispositions that will help them in intercultural exchanges of teaching and learning. The author then explores what such knowledge and dispositions might entail through an analysis of Satellite Kids. The play's focus on issues of power, identity, and intercultural conflict within a Canadian cosmopolitan school makes an interesting case study for exploring what intercultural knowledge and dispositions might look and sound like, and how the educational project of building intercultural capital is different from the project of multicultural education that has been dominant in Western teacher education throughout 1970s, 1980s, and 1990s.     

Multiple Perspectives on Family Relationships: A Latent Variables Model

Many scholars are skeptical of family member reports on their interpersonal relationships. Familial reports are assumed to be biased by social desirability as well as other factors. In this study, a latent variables modeling approach was employed to evaluate rater reliability and bias in mother, father, and child ratings of parent-child negativity. Results based on 78 clinical families demonstrate that family member ratings contain a significant "true score" component that correlates with observer ratings of parental behavior. The presence of systematic rater effects is also demonstrated. The latent variables approach, which provides statistical control for rater effects, is recommended for the analysis of this type of data.     

International Adult Literacy Survey (IALS): An analysis of international comparisons of adult literacy

The International Adult Literacy Survey (IALS) raises a number of important issues that are inherent in all attempts to make comparisons of cognitive and behavioural attributes across countries. This article discusses both the statistical and interpretational problems. A detailed analysis of the survey instruments is carried out to demonstrate the cultural specificity involved. The data modelling techniques used in IALS are critiqued and alternative analyses performed. The article argues for extreme caution in interpreting results in the light of the weaknesses of the survey.     

Neuropsychological treatment of dyslexia in the classroom setting

The purpose of this study was to validate Bakker's (1990, 1992) clinical neuropsychological balance model of dyslexia when implemented in a traditional general education classroom environment. The sample included 45 middle school, right-handed boys and girls (mean age = 12.78) with L-type dyslexia (excessively fast readers who make substantive reading errors), P-type dyslexia (displaying accurate but slow and laborious reading), and M-type dyslexia (readers who commit a combination of L-type and P-type dyslexia errors). The experimental groups (L and P type dyslexia) were presented with hemisphere specific stimulation (HSS) and hemispheric alluding stimuli (HAS). HSS involves the presentation of words into the right visual field (RVF) or the left visual field (LVF) or through tactile exercises with the right or left hand. HAS is achieved by constructing semantically and phonetically challenging letters and words. The children with M-type dyslexia served as a control group and received traditional decoding and comprehension exercises. The readers were exposed to a specific treatment model for 16 weeks, depending on their reading accuracy and comprehension. Statistical analyses indicated that, although there were no significant changes in word recognition for the dyslexia subtypes, the readers with L-type, P-type, and M-type dyslexia exhibited significant improvement in reading accuracy and comprehension as assessed by results from pretest to posttest. These results suggest that Bakker's clinical neuropsychological intervention can be effectively applied to the general education setting as well.     

The evolution of school league tables in England 1992–2016: ‘Contextual value‐added’, ‘expected progress’ and ‘progress 8’

Since 1992, the UK Government has published so‐called ‘school league tables’ summarising the average General Certificate of Secondary Education (GCSE) ‘attainment’ and ‘progress’ made by pupils in each state‐funded secondary school in England. While the headline measure of school attainment has remained the percentage of pupils achieving five or more good GCSEs, the headline measure of school progress has changed from ‘value‐added’ (2002–2005) to ‘contextual value‐added’ (2006–2010) to ‘expected progress’ (2011–2015) to ‘progress 8’ (2016–). This paper charts this evolution with a critical eye. First, we describe the headline measures of school progress. Second, we question the Government's justifications for scrapping contextual value‐added. Third, we argue that the current expected progress measure suffers from fundamental design flaws. Fourth, we examine the stability of school rankings across contextual value‐added and expected progress. Fifth, we discuss the extent to which progress 8 will address the weaknesses of expected progress. We conclude that all these progress measures and school league tables more generally should be viewed with far more scepticism and interpreted far more cautiously than they have often been to date.
