Le défi de l’intégration de l’approche par compétences lors de la sélection : conception d’un test de jugement situationnel ciblant le rôle CanMEDS de collaborateur pour la sélection au niveau postdoctoral en médecine

Introduction : L’approche par compétences est maintenant bien ancrée dans l’enseignement au niveau de la formation médicale postdoctorale. Dans ce contexte, un système de sélection également axé sur les compétences pourrait être avantageux. L’objectif principal de ce projet était de concevoir un TJS ciblant le rôle CanMEDS de collaborateur pour la sélection au niveau postdoctoral en médecine interne (MI) et en médecine familiale (MF). Méthodologie : Des entrevues d’incidents critiques ont été réalisées auprès de résidents juniors en MI ou en MF afin de générer les items du TJS. Trois leaders de l’approche par compétences ont révisé le contenu du test. Les items ont été analysés pour identifier la compétence principale du rôle CanMEDS de collaborateur, le contexte ainsi que les membres de l’équipe interprofessionnelle représentés dans les vignettes. La clé de correction a été déterminée par un panel composé de 11 experts. Cinq méthodes de notation ont été comparées. Résultats : Sept entrevues ont été réalisées. Après révision, 33 items ont été conservés dans le TJS. Les compétences clés du rôle CanMEDS de collaborateur, les contextes et les divers membres de l’équipe interprofessionnelle étaient bien distribués au travers des items. La moyenne des scores des experts variait entre 43,4 et 75,6 % en fonction des différentes méthodes de notation. Le coefficient de corrélation de Pearson entre les cinq méthodes de notation variait entre 0,80 et 0,98. Conclusion : Ce projet démontre la possibilité de concevoir un TJS utilisant le cadre CanMEDS comme trame de fond pour l’élaboration de son contenu. Ce test, couplé à une approche globale de sélection basée sur les compétences, pourrait éventuellement améliorer le pouvoir prédictif du processus de sélection au niveau de la formation médicale postdoctorale.

Clinical teaching: Maintaining an educational role for doctors in the new health care environment

Context and objectives: Good clinical teaching is central to medical education but there is concern about maintaining this in contemporary, pressured health care environments. This paper aims to demonstrate that good clinical practice is at the heart of good clinical teaching. Methods: Seven roles are used as a framework for analysing good clinical teaching. The roles are medical expert, communicator, collaborator, manager, advocate, scholar and professional. Results: The analysis of clinical teaching and clinical practice demonstrates that they are closely linked. As experts, clinical teachers are involved in research, information retrieval and sharing of knowledge or teaching. Good communication with trainees, patients and colleagues defines teaching excellence. Clinicians can 'teach' collaboration by acting as role models and by encouraging learners to understand the responsibilities of other health professionals. As managers, clinicians can apply their skills to the effective management of learning resources. Similarly skills as advocates at the individual, community and population level can be passed on in educational encounters. The clinicians' responsibilities as scholars are most readily applied to teaching activities. Clinicians have clear roles in taking scholarly approaches to their practice and demonstrating them to others. Conclusion: Good clinical teaching is concerned with providing role models for good practice, making good practice visible and explaining it to trainees. This is the very basis of clinicians as professionals, the seventh role, and should be the foundation for the further development of clinicians as excellent clinical teachers.

The role of microcomputer-based laboratory display in supporting the construction of new understanding in kinematics

Teachers' failure to utilise MBL activities more widely may be due to not recognising their capacity to transform the nature of laboratory activities to be more consistent with contemporary constructivist theories of learning. This research aimed to increase understanding of how MBL activities specifically designed to be consistent with a constructivist theory of learning support or constrain student construction of understanding. The first author conducted the research with his Year 11 physics class of 29 students. Dyads completed nine tasks relating to kinematics using a Predict-Observe-Explain format. Data sources included video and audio recordings of students and teacher during four 70-minute sessions, students' display graphs and written notes, semi-structured student interviews, and the teacher's journal. The study identifies the actors and describes the patterns of interactions in the MBL. Analysis of students' discourse and actions identified many instances where students' initial understanding of kinematics were mediated in multiple ways. Students invented numerous techniques for manipulating data in the service of their emerging understanding. The findings are presented as eight assertions. Recommendations are made for developing pedagogical strategies incorporating MBL activities which will likely catalyse student construction of understanding.

Sexual selection in a tropical fruit fly : role of a plant derived chemical in mate choice

The specific mechanisms by which selective pressures affect individuals are often difficult to resolve. In tephritid fruit flies, males respond strongly and positively to certain plant derived chemicals. Sexual selection by female choice has been hypothesized as the mechanism driving this behaviour in certain species, as females preferentially mate with males that have fed on these chemicals. This hypothesis is, to date, based on studies of only very few species and its generality is largely untested. We tested the hypothesis on different spatial scales (small cage and seminatural field-cage) using the monophagous fruit fly, Bactrocera cacuminata. This species is known to respond to methyl eugenol (ME), a chemical found in many plant species and one upon which previous studies have focused. Contrary to expectation, no obvious female choice was apparent in selecting ME-fed males over unfed males as measured by the number of matings achieved over time, copulation duration, or time of copulation initiation. However, the number of matings achieved by ME-fed males was significantly greater than unfed males 16 and 32 days after exposure to ME in small cages (but not in a field-cage). This delayed advantage suggests that ME may not influence the pheromone system of B. cacuminata but may have other consequences, acting on some other fitness consequence (e.g., enhancement of physiology or survival) of male exposure to these chemicals. We discuss the ecological and evolutionary implications of our findings to explore alternate hypotheses to explain the patterns of response of dacine fruit flies to specific plant-derived chemicals.
