Analysing lexical richness in French learner language: what frequency lists and teacher judgements can tell us about basic and advanced words

We show how teacher judgements can be used to assess the quality of vocabulary used by L2 learners of French.

Advanced skills teachers: professional identity and status

The teaching profession continues to struggle with defining itself in relation to other professions. Even though public opinion positions teachers second only to doctors and nurses in terms of their professional status and prestige research in the UK suggests that teachers still believe that they have much lower status than other professions. With teacher job satisfaction considerably lower today than the past and on-going issues with teacher recruitment and retention, new government policies have set out to enhance the status of teachers both within and outside of the profession. The Advanced Skill Teacher (AST) grade was introduced in 1998 as a means to recognise and reward teaching expertise and was framed as a way of also raising the status of the teaching profession. As to what a teaching professional should look like, the AST was in many ways positioned as the embodiment. Using survey data from 849 ASTs and in depth interviews with 31, this paper seeks to explores the ways that the AST designation impacts or not on teachers’ perceptions of their professional identity. In particular, the paper considers whether such awards contribute in positive ways to a teacher’s sense of professional identity and status. The results from the research suggest that teaching grades that recognise and reward teaching excellence do contribute in important ways to a teachers’ professional identity via an increased sense of recognition, reward and job satisfaction. The results from this research also suggest that recognising the skills and expertise of teachers is clearly important in supporting teacher retention. This is because as it allows highly accomplished teachers to remain where they want to be and that is the classroom.

Advanced global optimisation for mission analysis and design

This report describes the analysis and development of novel tools for the global optimisation of relevant mission design problems. A taxonomy was created for mission design problems, and an empirical analysis of their optimisational complexity performed - it was demonstrated that the use of global optimisation was necessary on most classes and informed the selection of appropriate global algorithms. The selected algorithms were then applied to the di®erent problem classes: Di®erential Evolution was found to be the most e±cient. Considering the speci¯c problem of multiple gravity assist trajectory design, a search space pruning algorithm was developed that displays both polynomial time and space complexity. Empirically, this was shown to typically achieve search space reductions of greater than six orders of magnitude, thus reducing signi¯cantly the complexity of the subsequent optimisation. The algorithm was fully implemented in a software package that allows simple visualisation of high-dimensional search spaces, and e®ective optimisation over the reduced search bounds.

‘Superteachers’, saints and solitaires: an investigation into advanced skills teachers of drama

This paper reports on a survey conducted in 2010 among ASTs who identified themselves as being specialists in, or having responsibility for, the subject of drama. The survey endeavoured to explore the professional backgrounds and experiences of these ASTs and gain insights into what they enjoyed about the role. It was especially concerned to address the following questions: 1. What general skills do ASTs in drama think they need to possess? 2. What subject specific knowledge and skills do they feel are needed to satisfy the demands of their role? In addition, insights were sought into what training and support had been afforded them, how they regarded themselves and were regarded by others in the role.

The physical pendulum in an advanced undergraduate course in mechanics

The physical pendulum treated with a Hamiltonian formulation is a natural topic for study in a course in advanced classical mechanics. For the past three years, we have been offering a series of problem sets studying this system numerically in our third-year undergraduate courses in mechanics. The problem sets investigate the physics of the pendulum in ways not easily accessible without computer technology and explore various algorithms for solving mechanics problems. Our computational physics is based on Mathematica with some C communicating with Mathematica, although nothing in this paper is dependent on that choice. We have nonetheless found this system, and particularly its graphics, to be a good one for use with undergraduates.

Delivering high-level food industry skills for future food security through Advanced Training Partnerships

The UK Biotechnology and Biological Sciences Research Council’s Advanced Training Partnerships initiative represents a significant investment in the provision of high-level skills for the UK food industry sector to address global food security from farm to fork. This paper summarises the background, aims and scope of the Advanced Training Partnerships, their development so far, and offers a view on future directions and evaluation of impact.

Retrieval characteristics of non-linear sea surface temperature from the Advanced Very High Resolution Radiometer

Criteria are proposed for evaluating sea surface temperature (SST) retrieved from satellite infra-red imagery: bias should be small on regional scales; sensitivity to atmospheric humidity should be small; and sensitivity of retrieved SST to surface temperature should be close to 1 K K−1. Their application is illustrated for non-linear sea surface temperature (NLSST) estimates. 233929 observations from the Advanced Very High Resolution Radiometer (AVHRR) on Metop-A are matched with in situ data and numerical weather prediction (NWP) fields. NLSST coefficients derived from these matches have regional biases from −0.5 to +0.3 K. Using radiative transfer modelling we find that a 10% increase in humidity alone can change the retrieved NLSST by between −0.5 K and +0.1 K. A 1 K increase in SST changes NLSST by <0.5 K in extreme cases. The validity of estimates of sensitivity by radiative transfer modelling is confirmed empirically.
