Curricular expertise is reflected in teachers' abilities to select and
convey content appropriate to the learner within a particular context
ual setting and situation. Teachers' knowledge and beliefs are instrum
ental in the curriculum decision-making process. Knowledge is often de
fined as factual information that has been agreed upon by scholars wit
hin a discipline. Beliefs are more personal and experiential in origin
and appear to influence what and how knowledge will be used. Beliefs
may also play a part in knowledge disavowal. Disavowal occurs when ind
ividuals choose to reject information that might otherwise change curr
ent practice. The acceptance or rejection of new knowledge is instrume
ntal in curriculum innovation and in the enhancement of student learni
ng in physical education.
