From pedagogical confrontations to pedagogical invitations: A self-study of teacher educators' work

For teacher educators, ethical dilemmas, tensions and 'pedagogical confrontations' (PCs) often arise in day-to-day teaching practice. Education research reveals that self-study researchers usually have a heightened awareness of their obligations to both identify and subsequently act on these dilemmas, tensions and confrontations (Berry, 2007; Bullough & Pinnegar, 2004; East, Fitzgerald & Heston, 2009; LaBoskey, 2004; Loughran, 2006; Pinnegar & Hamilton, 2009, 2015; Samaras, 2011 ). This self-study research focuses on the identification, categorization and analysis of 'pedagogical confrontations' (PCs) and asks what they mean for teacher educators. Through selfstudy and analysis of these 'pedagogical confrontations' we have come to understand more about the sophisticated and complex nature of teaching. Furthermore, we explore the way in which the use of PCs as a lens for researching practice, has subsequently led to new insights and led to an 'enactment in practice' (Loughran, 2006)

Taking on choice and control in personal care and support : the experiences of physically disabled young adults

Summary: Research on self-directed care has focused on older people and adults with learning disabilities or mental health difficulties. This paper reports physically disabled young adults’ experiences of self-directed care. Such work is important because young adults are a ‘minority’ group within adult social care. This, and their still developing life skills and lack of life experience, may have a bearing on their experiences of self-directed care and associated support needs. An exploratory qualitative study using semi-structured interviews investigated this issue. Participants were aged 19-29 years with a range of congenital and acquired impairments. Findings: Many aspects of interviewees’ experiences of self-directed care appeared to be influenced by their limited life experience, the fact they are still developing life skills and are a minority group within adult social care. Interviewees identified their lack of life experience and self-confidence as making them cautious in assuming responsibility for their care arrangements and, typically, their desire for on-going parental support. They also believed their age and life stage contributed to difficulties managing carers and PAs. Preferences around the characteristics of carers/PAs were influenced by their age and desire to integrate into mainstream activities. Information provided by statutory services did not (fully) acknowledge that some users were young adults. Applications: Compared to other physically disabled users of adult social care, young adults’ under-developed life skills and lack of life experience influences their experiences as users, and the support they needed to assume control of their care arrangements. Tailored information and support for this ‘minority group’ is required. Keywords: self- or consumer-directed support; personalization; adult social care; physical disability; young adults; transitio

How can technology make this work? Preservice teachers, off-campus learning and digital portfolios

Utilising appropriate Information Communication Technologies (ICT) as instructional tools in teacher education can be a challenging yet worthwhile endeavour. This paper reports the difficulties and benefits of a recent inter-university project requiring preservice primary teachers to construct professional digital portfolios using the support of ICT. Challenges with regard to communication and learning were numerous as 34 preservice teachers (PSTs) from three universities in NSW (situated in country towns, and in Sydney) worked together as a collaborative learning community. Meeting regularly face-to-face during the 12-month process was not always possible and so ICT resources were employed to facilitate instruction and communication. An action research methodology generated a data set of surveys, observational field notes, and student assessment artefacts. We share the findings in this paper so that others may learn from our experiences in using free access software and commonplace hardware when constructing digital portfolios with students who are some distance from campus

Can We Agree What Skilled Mindfulness-Based Teaching Looks Like? Lessons From Studying the MBI:TAC

BackgroundThe Mindfulness-Based Interventions: Teaching Assessment Criteria (MBI:TAC) is a widely used tool for assessing fidelity in mindfulness-based program (MBP) research and training. It also supports MBP teacher reflective and skill development. MBI:TAC assessors review MBP teaching and rate the teaching on 6 domains. The MBI:TAC yields individual domain and overall scores, using 6 levels of competence. Although the MBI:TAC is widely used in MBP research and training, research is at an early stage.ObjectiveWe developed and tested a method of training MBI:TAC assessors to use the tool reliably and examined interrater reliability of the tool.MethodsA total of 31 international senior MBP teachers were recruited to join an online training to build their skills in using the MBI:TAC. The training systematically and iteratively built familiarity and skills in assessing the 6 MBI:TAC domains. Qualitative and quantitative data on trainee's experience of the training were gathered. Interrater reliability in using the tool was tested each week of the training. At the end of the training, interrater reliability was tested by asking trainees to individually assess videos that they had not previously seen. Their ratings were compared to benchmark assessments, which had been established via consensus agreement between 4 expert users of the MBI:TAC.ResultsThe training was well received and appreciated, with some challenges experienced in applying the assessment methodology. Participants' ratings became progressively more in line with one another and the benchmark ratings during the training. At the end, interrater reliability was high (ranging from 0.67 to 1.0).ConclusionIt is possible for senior MBP trainers, coming from different regions in the world, to align toward common understandings of the elements of MBP teaching competence and program integrity. An assessor training methodology was tested, and the learning from this project has led to refinements for future delivery

Malonyl-CoA Mediates Leptin Hypothalamic Control of Feeding Independent of Inhibition of CPT-1a

Hypothalamic fatty acid metabolism is involved in central nervous system controls of feeding and energy balance. Malonyl-CoA, an intermediate of fatty acid biosynthesis, is emerging as a significant player in these processes. Notably, hypothalamic malonyl-CoA has been implicated in leptin's feeding effect. Leptin treatment increases malonyl-CoA level in the hypothalamic arcuate nucleus (Arc), and this increase is required for leptin-induced decrease in food intake. However, the intracellular downstream mediators of malonyl-CoA's feeding effect have not been identified. A primary biochemical action of malonyl-CoA is the inhibition of the acyltransferase activity of carnitine palmitoyltransferase-1 (CPT-1). In the hypothalamus, the predominant isoform of CPT-1 that possesses the acyltransferase activity is CPT-1 liver type (CPT-1a). To address the role of CPT-1a in malonyl-CoA's anorectic action, we used a recombinant adenovirus expressing a mutant CPT-1a that is insensitive to malonyl-CoA inhibition. We show that Arc overexpression of the mutant CPT-1a blocked the malonyl-CoA-mediated inhibition of CPT-1 activity. However, the overexpression of this mutant did not affect the anorectic actions of leptin or central cerulenin for which an increase in Arc malonyl-CoA level is also required. Thus, CPT-1a does not appear to be involved in the malonyl-CoA's anorectic actions induced by leptin. Furthermore, long-chain fatty acyl-CoAs, substrates of CPT-1a, dissociate from malonyl-CoA's actions in the Arc under different feeding states. Together, our results suggest that Arc intracellular mechanisms of malonyl-CoA's anorectic actions induced by leptin are independent of CPT-1a. The data suggest that target(s), rather than CPT-1a, mediates malonyl-CoA action on feeding
