This exploratory study considered Larrivee’s assessment of teachers’ reflective practice levels by using a formative, weekly, online student evaluation of teaching (SET) tool through a virtual learning environment (VLE) as a means to encourage reflective practice. In-depth interviews were conducted with six faculty members in three departments at a university college in the UK. The study found that: (a) faculty who experienced surface-level reflection were more likely to have a reactive reflection style; and (b) faculty who experienced higher levels of reflection were more likely to have a proactive reflection style. Overall, the tool was found to be an efficient means of encouraging reflection by all participants and demonstrated that reflective practice could come about as a result of these weekly formative SETs. The study concludes with suggestions for academic development and future research on reflection that could be conducted using SETs via a VLE.

The application of surface force apparatus (SFA) capabilities in measuring interactions between surfaces over nanometer separations was described. The technique is used when both the materials are transparent. It was observed that the poorly reflecting surface produce fringes that have low contrast and low finesse. The results show that the technique is successful when the visibility of the interference fringes is maximized.

This paper reports on a small trial with 6 pre-service teachers who videoed their own teaching practices. The pre-service teachers used the tool to reflect on practice and to enhance their own understandings of themselves as teachers. The initial footage was used to by the pre-service teachers to gauge quite specific elements of their teaching: for example, were they asking effective questions, or were they responding appropriately to questions children asked and as always, what management strategies seemed to be working? Critical feedback from other students was initially „less than critical‟, but again over time, this also appeared to sharpen as they had more opportunity to use the technology. Initial embarrassment of being on screen was replaced with a professional approach to seeing the video as a tool for providing the opportunity to systematically deconstruct practices and for providing concrete feedback for improvement. Used in conjunction with teaching preparation courses, the videoed segments of teaching practice could be used to highlight exemplars, to show what actually happens in classrooms and to explain certain practices. Cunningham and Benedetto (2002) state “Recent developments in digital video technologies permit teacher candidates to collect, review, and manipulate video to demonstrate their growth as a professional and as a reflective practitioner.” However, in the development of the trial, the issue was raised by the pre-service teachers that they would be interested in keeping the videos as evidence of their teaching competence to be used in applications for teaching positions. In the small trial, ethics permission had not been gained for that to happen, but it is certainly a valid and viable possibility for the future. Currently prospective employers have to rely on paper applications which respond to selection criteria, evidence from pre-service teachers‟ teaching rounds and the subjective impressions of an interview. If students were able to present a 5 minute segment of them teaching, it might count for much more than any other evidence. Video capture of teaching practice would provide potential employers with an indication of a pre-service teacher‟s management strategies, relationships with children and a snapshot of a pre-service teacher‟s instructional practice. The idea of video-capture as a tool for pre-service teachers to illustrate teaching capabilities will be more fully investigated in this paper.

Mathematical modelling is one of the current focuses in the Singapore Mathematics Curriculum Framework. A multi-tiered teaching experiment using design research methodology was conducted to build teachers’ capacity in designing, facilitating, and evaluating learning during mathematical modelling tasks for Primary 5 students (aged 10-11). This paper illustrates the use of the retrospective analysis phase within design research cycles to activate a critical moment of teacher learning involving the interplay between questioning and listening during her first attempt at facilitating a mathematical modelling task. The teacher affirmed her deliberate focuses in the use of questions to (a) refine students’ models, (b) encourage articulation of student ideas in self-evaluation of the models, and (c) clarify and understand student reasoning. However, she also discovered the importance of interpretative listening in conjunction with questioning to promote more sophisticated mathematisation processes in model development. Implications from the use of the retrospective analysis phase on activating critical moments of learning during teacher education will be discussed.

Student evaluations of teaching (SETs) are the most frequent form of faculty performance in the classroom, though they tend to be used as summative rather than formative evaluations. In this chapter, a project involving the use of a virtual learning environment for formative, weekly SETs is explored from both the student and faculty point of view at a rural university college in the United Kingdom. This project encouraged student participation in creating the learning environment and faculty reflection on how to improve the student experience. From the student perspective, the weekly anonymous evaluations were useful for providing feedback; however, students tended to only respond if they were not satisfied with the faculty member. The exception to this was that some students were more motivated to complete the evaluation forms if they believed the faculty member was utilising their feedback. From the faculty perspective, the feedback was not as detailed as they had expected, and some questioned whether it was worth the effort of conducting formative evaluations if the response rate was so low. Others used the feedback for reflective purposes, and it was found that those that reflected on their work at higher levels tended to receive a greater year-on-year increase in their end of year teaching evaluations.

In an Australian Bachelor of Social Work degree, critical reflection is a process explicitly taught in a fourth year subject to students who have returned from their first field placement experience in agencies delivering social work programmes. The purpose of teaching critical reflection is to enable social work students to become autonomous and critical thinkers who can reflect on society, the role of social work and social work practices. The way critical reflection is taught in this fourth year social work unit relates closely to the aims of transformative learning. Transformative learning aims to assist students to become autonomous thinkers. Specifically, the critical reflection process taught in this subject aims to assist students to recognise their own and other people's frames of reference, to identify the dominant discourses circulating in making sense of their experience, to problematise their taken-for -granted ‘lived experience’, to reconceptualise identity categories, disrupt assumed causal relations and to reflect on how power relations are operating. Critical reflection often draws on many theoretical frameworks to enable the recognition of current modes of thinking and doing. In this paper, we will draw primarily on how post-structural theories, specifically Foucault's theorising, disrupt several taken-for-granted concepts in social work.
