Cognition in art education

Whilst it is accepted that art education is a cognitive endeavour, the value and contribution of cognition to art education is often deliberated. By examining literature concerning conceptions of cognition and contextualising studies with the findings of a 5-year artographic inquiry into cognition in the lived experiences of artist teachers, this article is able to present a case for the reinstatement of cognition and cognitive study across policy, practice and research in art education. The article shares a conceptual frame to assist engagement with cognition as a concept whilst presenting a strategy to support cognitive reinstatement in the changing climate of art education. Questions are posed and answered regarding cognition’s position in art education to bring reinstatement implications forward, such as its complexity and productivity within education. Recommendations, such as increased engagement, voice projection and visibility, are also suggested to infiltrate transformation in future materialisations of cognitive engagement in the policy, practice and research of art education.     

Discursive constructions of equity in Australian higher education: Imagined worlds and the case of people seeking asylum

There is a strong rationale for people seeking asylum and refugees given temporary protection to be key beneficiaries of Australian higher education equity practices. However, despite the extreme precarity they face, this group remains among the most educationally disadvantaged populations in Australia. Here, we use critical discourse analysis to examine the publicly available statements of 38 Australian universities to identify discursive representations of equity practices and connections, with our analytic gaze focused through the lens of people seeking asylum. Using a three-part analytic heuristic examining ‘statements’, ‘practices’ and ‘connections’, we offer a critical discourse analysis of how each public university expresses its commitment to the equity agenda in powerful stakeholder-facing documents—such as annual reports, strategic plans and media releases—and we compare this analysis against institutional stated practices with regard to people seeking asylum. In identifying misalignments between equity statements and stated practices, we suggest that institutional equity narratives articulate ‘imagined worlds’, in which all marginalised groups can access higher education. We argue that now is the time to move beyond these ‘imagined worlds’, to enact stated commitments to universal education, by instituting real and effective practices to facilitate equitable access to Australian higher education for people seeking asylum.     

Meaningful learning and creativity in virtual worlds

Virtual worlds open new possibilities for learners, prompting a reconsideration of how learning takes place, and setting education in a context of playfulness, delight and creativity. They provide environments in which it is not only possible but also necessary to generate and try out ideas. They therefore offer opportunities to explore new possibilities related to teaching and learning about creativity and to challenge assumptions about the creative capabilities of young learners. The research reported here focuses on a group of teenaged learners who worked together online in the virtual world of Second Life®, as well as using other online tools. It applies thematic analysis to a 120-post forum discussion carried out over two weeks, in which 19 learners and educators debated how to develop their virtual island, and sets this discussion in the context of ongoing interaction within this group. Their focus widened from building plans to cover the creation and maintenance of a community, creatively synthesising considerations relating to environment, ethics, governance, aesthetics and purpose. The teenagers’ creativity when dealing with this authentic problem extended well beyond the elements identified by England's National Curriculum, and was supported by staff's active and supportive engagement in the debate.     

Examination of the Six Minute Walk Test to Determine Functional Capacity in People with Chronic Heart Failure: A Systematic Review

Purpose: To evaluate the reliability and validity of the six-minute walk test (6MWT) with respect to its ability to predict functional capacity in patients with chronic heart failure. Methods: A systematic review was performed via 8 databases to assess relevant English language full-text articles published from January 1, 1980 to October 31, 2009. Participant characteristics, interventions, reliability, validity, and predictive value for each article with respect to functional capacity as defined by peak VO₂ levels were extracted and compared. Quality Assessment of Diagnostic Accuracy Studies (QUADAS) scores were determined for each study. Results: Fourteen studies met the selection criteria. Comparison of the studies investigating reliability shows that the 6MWT has good reproducibility. The 6MWT demonstrates moderate correlation with peak VO₂ levels, and ability to predict VO₂ (functional capacity) dependent on distance walked. Cut-off distances vary from 300 to 490 meters depending on the study; if total distance walked remains equal or less than these values, the 6MWT retains its strong predictive value. Conclusion: The 6MWT has good reliability, moderate validity, and a significant ability to predict functional capacity in patients with CHF who do not walk greater than 490 meters.Key Words: six-minute walk test, chronic heart failure, functional capacity, peak VO₂     

A GLOBE Collaboration to Develop Land Cover Data Collection and Analysis Protocols

Global Learning and Observations to Benefit the Environment (GLOBE) is an international environmental education and science partnership which coordinates the work of students (aged 5 to 18), teachers and scientists from 48 countries on five continents to study and better understand the global environment. Accurate ground reference data is fundamental to the use of remotely sensed data for land cover classification and mapping. Because very little ground reference data has been collected, the accuracy of many land cover maps may be questioned, thus accurate land cover ground reference data is an important need that could be addressed through GLOBE scientist-student collaboration. If earth systems scientists are to use student data, it is important that those data be as accurate as possible to ensure reliability of research results. Thus a key question for this research is whether student collected data are accurate enough to support rigorous scientific investigations. This paper describes results of the GLOBE Science-Education Team on Data Validation and Accuracy Assessment's collaboration with teachers and students to: (1) design and test the pre-protocol learning activities; (2) test the protocols intended to guide the collection and analysis of data; and (3) implement the learning activities and protocols to determine the relative accuracy of student collected versus professionally collected land cover data. To ensure the most accurate classification of land cover possible, a new international hierarchical land cover classification system, the Modified Unesco Classification (MUC) system was developed. GLOBE Data Collection Protocols and methods were designed and implemented to test the accuracy of student collected reference data were designed and implemented. Students who collected land cover reference data using GLOBE protocols, obtained data which are at least as accurate as that collected by professionals.     

Making the grade: teacher training for inclusive education: A systematic review

The role of teacher training, as it pertains to the adoption of inclusive education (IE) (European Journal of Special, 22, 2007, 367), is critical in realizing and achieving truly IE environments. Literature often reports poor or inadequate training with regard to IE practices (Preparing Teachers of the Deaf for a Complex, Jacksonville, FL). The purpose of this review was to examine North American and Australian research regarding teacher training for students with disabilities (SWD) with the goal of informing best practice. Of the 27 reviewed studies, teacher training interventions reported positive outcomes and showed improvements in the areas of teachers’ attitudes/perceptions, knowledge, and strategies/skill development (Teacher Education and Special Education: The Journal of the Teacher Education Division of the Council for Exceptional Children, 32, 2009, 166) regarding IE SWD. The researchers cautiously recommend the employment of workshop style approaches as they appear to have the capacity to tackle all three outcome variables concurrently and within the shortest timeframe. Our restrained recommendations for best practice are born out of the quality of evidence presented within the reviewed studies.     

The characterization of commercial artists’ alkyd paints

There is little information in the conservation literature with respect to artists’ alkyd paints; thus, artists and conservators are somewhat at a loss about how to use and treat alkyds. Recently, analytical methods have been developed to identify the components in these polymers (oil modified polyesters), rates of cross-linking and mechanical properties. Presented in this paper are some of the characterization results of artists’ alkyd paints using THM (thermally assisted hydrolysis and methylation) gas chromatography– mass spectrometry (THM–GC/MS) and Fourier transform infrared spectroscopy–attenuated total reflectance (FTIR–ATR). Four brands of artists’ alkyd paints containing alkyd resin have been analysed; one containing a phthalic anhydride and pentaerythritol based alkyd resin, two containing isophthalic acid and pentaerythritol based alkyd resins, and the final one containing both phthalic anhydride and isophthalic acid and pentaerythritol based resins among the colours studied.     

Comparison of physiological responses to graded exercise test performance in outrigger canoeing

The aim of this study was to establish a graded exercise test protocol for determining the peak physiological responses of female outrigger canoeists. Seventeen trained female outrigger canoeists completed two outrigger ergometer graded exercise test protocols in random order: (1) 25 W power output for 2 min increasing by 7.5 W every minute until exhaustion; and (2) 25 W power output for 2 min increasing by 15 W every 2 min to exhaustion. Heart rate and power output were recorded every 15 s. Expired air was collected continuously and sampled for analysis at 15-s intervals, while blood lactate concentration was measured immediately after and 3, 5, and 7 min after exercise. The peak physiological and performance variables examined included peak oxygen uptake (VO2peak), minute ventilation, tidal volume, ventilatory thresholds 1 and 2, respiratory rate, respiratory exchange ratio, heart rate, blood lactate concentration, power output, performance time, and time to VO2peak. There were no significant differences in peak physiological responses, ventilatory thresholds or performance variables between the two graded exercise test protocols. Despite no significant differences between protocols, due to the large limits of agreement evident between protocols for the peak physiological responses, it is recommended that the same protocol be used for all comparison testing to minimize intra-individual variability of results.
