What drives students' self-directed learning in a hybrid PBL curriculum.
Evidence supporting Problem-based learning (PBL) fostering students' self-directed learning (SDL) in hybrid PBL curricula is inconsistent. To explore the influence of PBL in a hybrid curriculum on students' SDL, the authors investigated the following: (1) students' self-assessed SDL ability, (2) students' perceptions of the influence of curricular components on SDL, and (3) the relationships between curricular elements and SDL. The research questions were explored both quantitatively and qualitatively. ⋯ Findings from students and faculty focus group supported the perceived positive influence of the curriculum on SDL. This study found that students' perceived SDL ability was positively influenced by several components of the hybrid PBL curriculum. However, further investigations are needed for a clearer understanding of the specific effects of the hybrid PBL curriculum on students' SDL.

ReviewOral assessment and postgraduate medical examinations: establishing conditions for validity, reliability and fairness.
The purpose of this review was to examine the practice of oral assessment in postgraduate medical education in the context of the core assessment constructs of validity, reliability and fairness. Although oral assessment has a long history in the certification process of medical specialists and is a well-established part of such proceedings for a wide range of specialties in most countries, there remains concern regarding its use. ⋯ Supporting high quality published research into examination practices and outcomes and acting on the findings of such research is needed urgently to allay concerns about the transparency and fairness of these examinations, especially when assessing international medical graduates. The article concludes by proposing 15 conditions under which oral assessment is valid, reliable and fair.

Cognitive elements in clinical decision-making: toward a cognitive model for medical education and understanding clinical reasoning.
Physician cognition, metacognition and affect may have an impact upon the quality of clinical reasoning. The purpose of this study was to examine the relationship between measures of physician metacognition and affect and patient outcomes in obstetric practice. Reflective coping (RC), proactive coping, need for cognition (NFC), tolerance for ambiguity, state-trait anxiety and metacognitive awareness were assessed for obstetricians (n = 12) who provided intra-partum care to 4,149 women. ⋯ Obstetricians high in trait anxiety were more likely to perform a mid forceps delivery (OR 2.49, p = 0.01) or a vacuum delivery (OR 5.08, p = 0.003), and less likely to supervise a spontaneous vaginal delivery (OR 0.38, p < 0.0001). NFC was negatively associated (OR 0.10, p < 0.001) and trait anxiety was positively associated with intrapartum asphyxia (p < 0.05, rho = 0.582). In summary, physician cognitive processes and affect have a significant impact on patient outcomes, particularly in situations where there is a higher level of clinical unpredictability.

Multicenter StudyTwo models of raters in a structured oral examination: does it make a difference?
Oral examinations have become more standardized over recent years. Traditionally a small number of raters were used for this type of examination. Past studies suggested that more raters should improve reliability. ⋯ Reliability was higher for the candidate-specific raters. Inter-rater reliability, internal consistency and a study of station inter-correlations suggested that a halo effect may be present for candidates examined by candidate-specific raters. This study suggests that although the model of candidate-specific raters was more reliable than the model of station-specific raters for the overall examination, the presence of a halo effect may influence individual examination outcomes.

Increased authenticity in practical assessment using emergency case OSCE stations.
In case of an emergency, a fast and structured patient management is crucial for patient's outcome. The competencies needed should be acquired and assessed during medical education. The objective structured clinical examination (OSCE) is a valid and reliable assessment format to evaluate practical skills. ⋯ They rated ECOS to be more realistic in comparison to the traditional OSCE scenarios. The reliability estimated via Crohnbach's alpha for the 6 ECOS is high (0.793). ECOS offer a feasible alternative to the traditional OSCE stations with adequate reliability to assess students' capabilities to cope with an acute emergency in a realistic encounter.
