Congruence between student and instructor perceptions of clinical teaching in paediatrics.

The purpose of this study was to examine the similarities and differences in what students and instructors perceive to be the importance, and instructor use of, representative effective clinical teaching skills noted in the literature. Teaching staff members (n = 74) and students (n = 96) in three successive quarters in a required clerkship in paediatrics completed parallel forms of a clinical teaching survey. Providing feedback and positive reinforcement, showing personal interest in students, communicating knowledge and learning objectives effectively, motivating students, exhibiting knowledge of current practice and physical diagnosis, and spending time reviewing histories and demonstrating and supervising physical examinations were all thought to be important by both students and teaching staff members. Both students and instructors, however, perceived history/physical examination skills to be somewhat less important than the other clinical teaching skills, although instructors believed this skill to be significantly more important than did students. In general there was a great deal of consistency and reliability among student and instructor perceptions of the importance of these representative effective clinical teaching skills. In contrast, teaching staff members consistently believed they used each skill significantly more than students judged they did. Not surprisingly, the more important that teaching staff members believed each skill to be, the more they reported using that skill in their own teaching. These findings suggest that it is important for clinical instructors to be vigilant in assessing the effectiveness of their teaching methods.

Relationship of the sarcoplasmic reticulum to fibril and triadic junction development in skeletal muscle fibers of fetal monkeys and humans.

Examinations of stages of fibril development in muscle fibers of seven Rhesus monkey and six human fetuses reveal SR tubules encircling the Z lines at all stages of fibril development. The encircling SR tubules are continuous with the SR network of tubules which is found surrounding fibrils at all stages of development observed. The SR tubules encircling the Z lines show connections (electron-opaque strands) with the Z lines. The developing triadic junction shows a progressive increase in complexity of structures within the junction. First, membranes of T and SR become apposed with no visible structure between them- Second, tenuous connections are found traversing the space between apposed membranes. Third, well developed bridges are seen traversing the space. And finally, an intermediate density midway between the apposed membranes and parallel to them is found in favorable sections. Junctions between T tubule membranes were also observed and the structures in these junctions are somewhat similar to those found in junctions between T and SR membranes. The change in orientation of triads from predominantly longitudinal to predominantly transverse is complete in the 18-week monkey fetus and incomplete in the latest stage (28-week) of fetal development observed in humans.
