The Effect Over Time of a Video-Based Reflection System on Preservice Teachers’ Oral Presentations

Abstract

We report the development of preservice teachers' oral presentation performance based on a technology-mediated video reflection system. Participants video-recorded oral presentations and uploaded them to an online blog to view and reflect on their performance and that of their peers. Four presentations by forty-one participants were analysed using a range of criteria based on what we call the Modes of Communication (voice, body-language, words and alignment between them) and the Constructed Impression of the communication acts (confidence, clarity, engagement and appropriateness). Results indicate a significant improvement across all criteria with a decreased rate of improvement for later iterations.

A Systematic Review of the Research on the Knowledge and Skills of Australian Preservice Teachers

“…The research on pedagogical content knowledge is less clear, but some of the studies here indicate that practice teaching, analysis of actual teaching, and practice in writing lesson plans and program sequences (Beswick & Muir, 2013;Dawkins et al, 2009;Lloyd & Mukerjee, 2012) may help pedagogical skills and knowledge. The study by Cavanagh et al (2014), even though the skills were judged inadequate based on the results, showed that PSTs can improve practical and essential communication skills when provided with multiple opportunities for practice with feedback.…”

“…Universities must be open to more research that allows these comparisons to be made, as well as research that explores general levels of PST knowledge. ✓ N Self injury Berger et al (2015) ✓ N Evidence-based practice Carter et al (2015) ✓ N Communication skills Cavanagh et al (2014) ✓ N Values education Christian (2014) ✓ N Physical education Dudley & Baxter (2009) ✓ Y Equity Fenwick & Cooper (2013) ✓ N Behaviour management Yeigh (2013) ✓ N ICT Fluck & Dowden (2011) ✓ N Table 1: Adequacy of PST Knowledge and Conditions in which it was assessed.…”

“…Judgements of the adequacy of the knowledge of the sample of PSTs in each article drew on author conclusions for all except six studies where reported results had to be used (Anderson et al, 2012;Cavanagh et al, 2014;Geng, 2013;Prieto et al, 2015;Taylor et al, 2006;Tetley & Jones, 2014). Table 1 (see appendix) shows the adequacy of knowledge for each article, and whether or not the assessment was under examination conditions.…”

“…Berger, et al (2015) Prior training in self-injury had no effect. Cavanagh et al (2014) Improvement in communication skills over the course of the unit (measured on four occasions). …”

Estimation of Presentations Skills Based on Slides and Audio Features

“…The objective of using slides is making presentations more structured and interesting to the audience [9]. Traditionally, automatic evaluation of presentations focus mainly on extraction of just one kind of cues, being those usually visual or audio cues [10]. This work explores several simple audio features based on the prosody of the speech for automatic assessment of the quality of presentations.…”
