Second career preservice teachers' perceptions about the out-of-field teaching phenomenon might influence career decisions, such as retention and attrition. A target group of 133 second career graduating Master of Teaching students voluntarily participated in this mixed method study which offered findings through analysed open and Likert-scale questions and semi-structured interview data. The pilot offers new information about second career preservice teachers' perceptions about their possible involvement in out-of-field teaching practices and the phenomenon's implications for capabilities, skills knowledge, self-efficacy, support needs and professional identity. A critical reflection on quality teaching and teacher training programs, and preparation for the teaching profession form the foundation for further research in this field. The analyses further stimulate a deeper understanding of the future second career teaching workforce and perceptions of support resources.

What is the focus of development (capabilities, skills, knowledge)? 2. What is the role of reflective practice (in situ, post) for individual staff (reflecting on personal development, reflecting on the field of academic / faculty development)? 3. How do we resource the development of teaching practice? 4. How understanding teaching practice and the out-of-field teaching phenomenon will contribute to improving academics’ views regarding the preparation of preservice teachers for workplace challenges and practice teaching 5. How can the information from this investigation develop teaching practice linked to possible out-of-field teaching positions to improve preparedness and support? 6. The pilot unveils information to support academics’ critical reflection on the alignment of current workplace concerns to the reality of preservice teacher preparation. [ABSTRACT FROM AUTHOR]

We develop a computationally efficient method for the theoretical analysis of thermophoresis of nanoparticles and adatoms on crystalline surfaces (thermal tweezers) for efficient parallel nanofabrication. The analysis of surface diffusion of particles or adatoms in the presence of strong temperature gradients is conducted through the direct determination of probability distributions for diffusing particles, using the numerical solution of the Smoluchowski diffusion equation with varying (temperature-dependent) diffusion constant. The local values of the diffusion constant are determined from the Fokker–Planck equation for the considered crystalline potential of the substrate and local temperature. Steady-state and nonsteady-state particle distributions on the surface are obtained and analyzed in the presence of optically-induced strong temperature gradients. Detailed comparison of this approach with the previously obtained results from the Monte Carlo simulations of the Langevin equation is conducted, demonstrating high computational efficiency, and accuracy of the new method in the high-friction regime. Applicability conditions for the developed method are also determined and discussed. [ABSTRACT FROM AUTHOR]

We conduct the detailed numerical investigation of a nanomanipulation and nanofabrication technique—thermal tweezers with dynamic evolution of surface temperature, caused by absorption of interfering laser pulses in a thin metal film or any other absorbing surface. This technique uses random Brownian forces in the presence of strong temperature modulation (surface thermophoresis) for effective manipulation of particles/adatoms with nanoscale resolution. Substantial redistribution of particles on the surface is shown to occur with the typical size of the obtained pattern elements of ∼100 nm, which is significantly smaller than the wavelength of the incident pulses used (532 nm). It is also demonstrated that thermal tweezers based on surface thermophoresis of particles/adatoms are much more effective in achieving permanent high maximum-to-minimum concentration ratios than bulk thermophoresis, which is explained by the interaction of diffusing particles with the periodic lattice potential on the surface. Typically required pulse regimes including pulse lengths and energies are also determined. The approach is applicable for reproducing any holographically achievable surface patterns, and can thus be used for engineering properties of surfaces including nanopatterning and design of surface metamaterials.
