Evaluation of the Learning to Teach for Social Justice–Beliefs Scale in an Australian context

A concern for social justice pervades the espoused curriculum of many pre-service teaching programmes, but the extent to which that curriculum influences the beliefs students hold is an open question. With the goal of developing an instrument suitable for evaluating such beliefs at the degree programme level, the present study analysed responses to the Learning to Teach for Social Justice–Beliefs (LTSJ–B) Scale (Enterline, S., Cochran-Smith, M., Ludlow, J.H., & Mitescu, E. (2008). Learning to teach for social justice: Measuring change in the beliefs of teacher candidates. The New Educator, 4, 267–290. doi:10.1080/15476880802430361) from 304 Australian pre-service teachers. Exploratory factor analysis and Rasch analysis both indicated a two-factor structure, driven by a methodological artefact of item valence. We conclude from these findings that a short, five-item version of the LTSJ–B Scale would suitably balance psychometric and pragmatic considerations, in the broader context of working within an institutionally aligned system of teaching evaluation with multiple levels.

Induced charge electro osmotic mixer: Obstacle shape optimization

Efficient mixing is difficult to achieve in miniaturized devices due to the nature of low Reynolds number flow. Mixing can be intentionally induced, however, if conducting or nonconducting obstacles are embedded within the microchannel. In the case of conducting obstacles, vortices can be generated in the vicinity of the obstacle due to induced charge electro-osmosis (ICEO) which enhances mixing of different streams: the obstacle shape affects the induced zeta potential on the conducting surface, which in turn influences the flow profile near the obstacle. This study deals with optimization of the geometric shape of a conducting obstacle for the purpose of micromixing. The obstacle boundary is parametrically represented by nonuniform rational B-spline curves. The optimal obstacle shape, which maximizes the mixing for given operating conditions, is found using genetic algorithms. Various case studies at different operating conditions demonstrated that the near right triangle shape provides optimal mixing in the ICEO flow dominant regime, whereas rectangular shape is the optimal shape in diffusion dominant regime. The tradeoff between mixing and transport is examined for symmetric and nonsymmetric obstacle shapes.     

The impact of training on pre-service teacher attitudes,concerns, and efficacy towards inclusion

Thirty pre-service teachers took part in a nine-week university course focussed on the benefits of inclusive education and the techniques needed to successfully implement it. The Teachers’ Attitudes Toward Inclusion Scale (TATIS), Concerns about Inclusive Education Scale (CIES), and Teacher’s Efficacy in Implementing Inclusive Practices (TEIP) were administered prior to and following the university course. Paired sample t-tests revealed that participants’ attitudes and efficacy increased significantly following the course while their concerns decreased significantly. Mixed design ANOVAs revealed that pre-service teachers without past experience of teaching students with disabilities had the largest improvement in attitudes. Pre-service teachers who were not acquainted with a person with a disability had significantly larger decreases in concern level and increases in efficacy level than those who were acquainted with a person with a disability. These results are discussed and implications for future research outlined.     

Cross-Cultural Validation of Four Positive Psychology Assessments for Use with a Ghanaian Population

This study reports the evaluation of four positive psychology assessments for use in clinical, education, and research settings with individuals in Ghana, Africa. The analyses attempted to identify validity evidence for internal structure and relationships with related variables for the Satisfaction with Life Scale (SLS; Diener et al. Journal of Personality Assessment, 49, 71–75, 1985), General Mattering Scale (GMS; Marcus 1991), Short Grit Scale (GS; Duckworth and Quinn Journal of Personality Assessment, 9, 166–174, 2009), and Brief Resilience Scale (BRS; Smith et al. International Journal of Behavioral Medicine, 15, 194–200, 2008). The data yielded from 657 Ghanaian participants indicated factor structures ranging from a strong model fit (SLS and GMS) to an acceptable fit following modifications to factor structure (GS and BRS), while evidence based on relationships to related variables was convincing. Implications for use of these assessments and for future research are discussed.
