THE MEDICAL DISCIPLINES MODEL.
In the discipline-based curriculum
structure recommended by Flexner, which prevailed until the 1960s,
students typically learn normal structures, functions, and processes of the
body organized by disciplines such as anatomy, physiology, microbiology,
histology, and biochemistry, followed by pathophysiology and disease
management. Discipline-specific courses are taught in parallel with other
disciplinary courses; too often, we found, there is little coordination or
reference to clinical relevance. Over time, new content areas such as
evidence-based medicine, genetics, and medical ethics have been added
as independent, concurrent courses.
The purpose of being immersed in science is not just to understand
the human body, according to Flexner, but also to ensure that physicians
in training would learn to use scientific reasoning, or the hypotheticodeductive
reasoning process. Although this approach is plausibly related
to learning to think through certain kinds of difficult problems, major
challenges have arisen with expansion of knowledge and proliferation of
disciplines. Learning in the medical curriculum today is difficult because
of the overwhelming amount of potential information to be mastered and
uncertainty about which information will be most relevant for the future.
Students struggling with factual overload may adopt learning strategies
such as rote memorization that are inimical to scientific reasoning and
inquiry.
Accordingly,
today very few schools structure the curriculum entirely
around separate discipline courses. One feature of this curricular
approach that we found to be of particular concern is that it requires
students to be the integrators of knowledge and find appropriate
application to clinical medicine. The curricular format does not integrate
content sequentially, leaving students to determine how the content in
one domain relates to another, and how both relate to patient care.
Curricula organized this way do not honor the premise that learning is
progressive and developmental. Students voice frustration with the lack
of coordination among lecturers who are unaware of the content covered
in preceding lectures or who fail to acknowledge and build on students'
existing knowledge.
Students are also critical of lecturers who fail to
discuss the relevance of scientific concepts to the practice of medicine.
A second problem with this curricular structure is its inefficiency.
Students are required to learn the content two entirely different ways,
first organized around basic science content and later organized around
patient signs and symptoms. As a consequence, students arrive in the
clinical setting with abstract knowledge that is difficult for them to
access and apply to patient care. This curricular structure is inconsistent
with the premise that learning is situated and distributed; it fails to
capitalize on the richness of the clinical context early on and to engage
learners authentically in using their knowledge and skills in the care of
patients.
Third, the pedagogies employed in the discipline-based model often
rely heavily on lectures that do not actively engage learners in constructing
conceptual understanding. Because the practical and experiential
aspects of the curriculum are segregated from the biomedical content,
many students fail to understand and appreciate the interconnectedness
of these forms of knowledge. Students have little sense of the context
of the knowledge they are acquiring and the various means by which it
can be used in practice. Finally, the assessment system typically focuses
narrowly on scientific content knowledge and ignores such other important
domains of performance as synthesis, integration, and evaluation
of information and domains beyond bioscience, such as professionalism,
clinical skills, and systems improvement.
