A Model of How Different Biology Experts Explain Molecular and Cellular Mechanisms

Constructing explanations is an essential skill for all science learners. The goal of this project was to model the key components of expert explanation of molecular and cellular mechanisms. As such, we asked: What is an appropriate model of the components of explanation used by biology experts to explain molecular and cellular mechanisms? Do explanations made by experts from different biology subdisciplines at a university support the validity of this model? Guided by the modeling framework of R. S. Justi and J. K. Gilbert, the validity of an initial model was tested by asking seven biologists to explain a molecular mechanism of their choice. Data were collected from interviews, artifacts, and drawings, and then subjected to thematic analysis. We found that biologists explained the specific activities and organization of entities of the mechanism. In addition, they contextualized explanations according to their biological and social significance; integrated explanations with methods, instruments, and measurements; and used analogies and narrated stories. The derived methods, analogies, context, and how themes informed the development of our final MACH model of mechanistic explanations. Future research will test the potential of the MACH model as a guiding framework for instruction to enhance the quality of student explanations.     

Methodology in Sports History: Learning from Legal Scholarship?

The brief note aims to illustrate how historical context has contributed to my writing on modern sports law and principally through two pieces of work – the first relating to the historical, sui generis origins of the legality of combat or fighting sports, which continues to stretch the boundaries of core principles of criminal law, such as reasonable consent to bodily harm, to their utmost; and second, and more generally, the ‘historicalegal’ influences on the development of modern sport in mid-nineteenth-century Britain. Before that is done, it is best to give some account of research methodologies in legal scholarship and principally as they apply to legal history.     

The effect of exploratory talk on the development of sentence structure in able writers

This one‐term practitioner research study, conducted with 33 Year 5 children, considers the impact of teaching exploratory talk skills on the learning of the class, with particular consideration of the development of the ability of gifted and talented children to manipulate and control sentence structure to create effect. Beginning with metatalk activities, the class defined new talk rules, putting them into practice in an action‐research project. The study then went on to consider the detailed application of these skills in a focus group of six gifted children. In order to meet with the requirements of a wider study, the impact of this focus group on the learning of the whole class was observed. While many children, both those in the focus group and the wider class, appeared to embrace exploratory talk as a route to independence of the class teacher, some children were more reluctant to engage. The article concludes with an evaluation of the impact of exploratory talk.     

Preparing a CPT Submission Package

The candidate chooses projects for his or her ability to establish credentials as a performance technologist. The clearer the links between actions and improved performance for the client, the stronger the case each example makes. Candidates will need to show this linkage between contribution and outcome for each project used in preparing the submission package.
