Different conceptual representations and the use of different key features might be a cause for inconsistent definitions of feedback. The characteristics, strengths and weaknesses of this research-based operational definition are discussed.
SUMMARY Shortage of teachers is one of the major challenges facing the teaching profession. One of its causes is the high proportion of dropout in initial teacher
The larger picture of variables that influence the process and outcome of feedback, relevant for medical education, shows many open spaces. We suggest that targeted studies be carried out to expand our knowledge of these important aspects of feedback in medical education.
Against a background of disappointing percentages of students choosing exact and technical studies and the academic choice research tradition, a study into the choice of physics in secondary education has been carried out. It focuses on the predictive value of certain characteristics of the curriculum, the differences between schools and the stability of the choice variable. Two cohorts of students in a representative sample of schools filled in written questionnaires, four times in two years. The data were analysed in several ways that complemented each other, including multilevel analysis. The main predictor of the choice of physics in secondary education is perceived future relevance and no significant differences between schools exist. The choice variable is not stable. Many students feel uncertain about their choice of study and profession. Academic choice processes should be more connected with career choice processes. Certain characteristics of the physics curriculum can be expected to further the possibilities for students to experience physics and physics-like contents and problems as being personally meaningful and interesting.
Factors influencing the successful introduction of portfolios are described. A portfolio is a purposeful collection of all kinds of documents and other artefacts that together give an impression of how tasks were fulfilled and how competence has developed. A portfolio can also contain reflections and plans for future development. Although portfolios are often promoted as valuable instruments in innovative educational practices, the introduction of portfolios in everyday education often leads to disappointment. Factors that influence the success of the introduction of portfolios are the match between the purpose of using a portfolio and the portfolio content and structure; the educational configuration in which the portfolio is introduced; the support of teachers, students and educational leaders; and the availability of an adequate infrastructure.
Feedback is considered important to acquire clinical skills. Research evidence shows that feedback does not always improve learning and its effects may be small. In many studies, a variety of variables involved in feedback provision may mask either one of their effects. E.g., there is reason to believe that the way oral feedback is framed may affect its effect if other variables are held constant. In a randomised controlled trial we investigated the effect of positively and negatively framed feedback messages on satisfaction, self-efficacy, and performance. A single blind randomised controlled between-subject design was used, with framing of the feedback message (positively-negatively) as independent variable and examination of hearing abilities as the task. First year medical students' (n = 59) satisfaction, self-efficacy, and performance were the dependent variables and were measured both directly after the intervention and after a 2 weeks delay. Students in the positively framed feedback condition were significantly more satisfied and showed significantly higher self-efficacy measured directly after the performance. Effect sizes found were large, i.e., partial η (2) = 0.43 and η (2) = 0.32 respectively. They showed a better performance throughout the whole study. Significant performance differences were found both at the initial performance and when measured 2 weeks after the intervention: effects were of medium size, respectively r = -.31 and r = -.32. Over time in both conditions performance and self-efficacy decreased. Framing the feedback message in either a positive or negative manner affects students' satisfaction and self-efficacy directly after the intervention be it that these effects seem to fade out over time. Performance may be enhanced by positive framing, but additional studies need to confirm this. We recommend using a positive frame when giving feedback on clinical skills.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
