Construct Validation of the Self-Efficacy Teaching and Knowledge Instrument for Science Teachers-Revised (SETAKIST-R): Lessons Learned

Described herein is the academic lineage and independent validation of the Self-Efficacy Teaching and Knowledge Instrument for Science Teachers-Revised (SETAKIST-R). Data from 334 K-12 science teachers were analyzed using Partial Credit Rasch models. Principal components analysis on the person-item residuals suggest two latent dimensions: Knowledge and Teaching Self-Efficacies. Item-fit statistics were used to select items for each subscale. Person and item separation (reliability) indices were quite low, and we noted disordered response patterns on the person-item maps that revealed problems with item content and/or scaling for both subscales. These issues include the presence of: verbal negatives, ambiguous modifiers, counter-intuitive scaling, and an “undecided/uncertain” option. The SETAKIST-R, in its current form, cannot be recommended as a measure of science teacher self-efficacy.     

Written expression performance in adolescents with attention-deficit/hyperactivity disorder (ADHD)

We examined written expression performance in a sample of adolescents with ADHD and subthreshold ADHD using two different strategies: examining performance on standardized measures of written expression and using other indicators of written expression developed in this study. We examined associations between standardized measures of written expression, cognitive processing measures (working memory, processing speed, language, fine motor ability, and reading efficiency) and behavioral ratings of ADHD by parents and teachers. We also developed a coding scheme for a writing sample to measure productivity and the ratio of self-corrections to errors. The results indicated that written expression performance was most consistently associated with cognitive processing measures and not behavioral ratings of ADHD, based on correlational and simultaneous regression analyses. These results were consistent in the analyses with both the standardized measures and the coding scheme measures of written expression. Findings generally remained robust, regardless of whether participants who met criteria for a learning disability were included or excluded in the analyses. The current results suggest that written expression difficulties in adolescents with ADHD are attributable to processing difficulties that may be associated with ADHD, not to ADHD reported symptoms. Implications for assessment and intervention are discussed.     

Motor control and sequencing of boys with Attention-Deficit/Hyperactivity Disorder (ADHD) during computer game play

The motor control of 49 unmedicated boys clinically diagnosed with ADHD, case‐matched with 49 non‐ADHD boys, was assessed while playing Crash Bandicoot I, a Sony^TM Playstation platform computer video game. In Crash Bandicoot participants control the movements of a small‐animated figure through a hazardous jungle environment. Operationally defined measures of motor control were designated by (1) the stage of the game completed (ie, the number of obstacles successfully passed) before losing the figure's ‘life’, (2) the level of complexity that the stage represented and (3) the time taken to get to that point during the video game play. These measures were assessed under contrasting conditions of low or high working memory and distracter loads. Four tasks were administered (totalling 12 trials), incorporating both with and without distracter conditions. For those trials with the distracter, a segment of the television show The Simpsons was simultaneously played on a television screen adjacent to the computer game monitor. A 5‐way MANOVA revealed that ADHD boys took less time to complete their trials under the direct condition (ie, no working memory load) on Crash Bandicoot, compared to their matched non‐ADHD peers. When the task required additional working memory, however, the ADHD boys took significantly longer. Cumulative frequency plots of game performance revealed that in terms of the number of obstacles completed, the control participants successfully navigated more obstacles on the low working memory load task than the ADHD participants, but that the performance of the two groups was less distinguishable on the high working memory load task. The findings have implications for assessment and management of children with ADHD.     

Challenging the post‐Fordist/flexible organisation thesis: the case of reformed educational organisations

This paper examines claims that recent reforms to UK education have led to significant organisational changes in primary school and higher education. It also examines two main theoretical explanations for these, namely post‐Fordism and New Managerialism. Examples of changes in both schools and universities, including flexibility and teamwork, are explored. Up to the mid‐1980s, publicly funded educational organisations did display bureaucratic features, including rules, staff hierarchies and complex procedures. However, professionals employed in these organisations retained discretion and autonomy in their work. Since then, the introduction of an audit culture and a greater emphasis on management and regulation of the work of teachers and academics has decreased discretion and autonomy. This paper suggests that theories of New Managerialism offer a more satisfactory explanation of the changes explored than post‐Fordism, which has more often been used as a normative model of what contemporary organisations should look like.     

Vexing questions that sustain sensemaking

Current science education reforms highlight the importance of students making sense of scientific ideas. While research has studied how to support sensemaking in classrooms, we still know very little about what drives students to pursue and persist in it on their own. In this article, we use a set of parallel case studies of undergraduate students discussing introductory physics to show how certain student-generated, vexing questions both initiate and sustain students' sensemaking processes. We examine affective and linguistic markers in student discourse in paired-clinical interviews to demonstrate both of these functions of vexing questions and detail their role in the explanations students construct. We conclude by discussing the implications of this analysis both for supporting sensemaking in classrooms and for studying it in research.     

Understanding teenagers' personal contexts to design technology that supports learning about energy consumption

Energy sustainability is prevalent in political and popular rhetoric and yet energy consumption is rising. Teenagers are an important category of future energy consumers, but little is known of their conceptions about energy and energy saving. We report on empirical research with two groups of teenagers. This is part of ongoing work to design learning technologies that support teenagers learn about personal energy consumption. In this paper we describe our analysis and methodology, which are shaped by the Ecology of Resources (EoR) design framework [Luckin, R. (2010). Re-designing learning contexts: Technology-rich, learner-centred ecologies. London and New York, NY: Routledge]. Our findings informed the development of an EoR model of the participants' personal context, which includes their world resources (people, tools, knowledge, skills, and environment) and their personal resources (conceptions, motivations and concerns around energy consumption). We discuss the range of methods we employed to understand learners' personal contexts. These findings contribute to our understanding of how to explore teenagers' personal contexts and have implications for the design of technology to support learning about personal energy consumption.     

From discrete intervention to engage marginalised students to whole-school initiative to engage all students

An enduring educational dilemma is that young people from economically disadvantaged backgrounds do not have their needs met in conventional schooling. As a result, many have left school by Year 11. To counter this trend, some schools in disadvantaged areas introduce targeted in-school interventions before Year 11 to meet the needs of their students. Many of these interventions, which are highly successful in engaging students and supporting them to achieve, have insights to offer schools, but they remain on the margins as programmes for particular young people. However, a government secondary school in Victoria, Australia has been an exception. It was inspired to apply aspects of a successful intervention, Hands On Learning, to a whole-school initiative to enhance the engagement of all of its students. I used a case-study approach to investigate the initiative’s first year of implementation. Findings revealed that the majority of students did report engagement. However, economically disadvantaged students faced barriers to full participation that negatively impacted their learning experiences. The inequitable distribution of educational benefits demonstrated that whole-school adaptation of an intervention is not straightforward and unless the needs of disadvantaged students are targeted in the whole-school initiative, they are likely to experience educational disadvantage.
