Objective. Clinical reasoning concepts can be viewed as descriptions o
f mental operations or as a thinking frame-a structure to organize and
support clinical thinking. This study examined an approach for teachi
ng clinical reasoning as a thinking frame to occupational therapy stud
ents. Method. A quasi-experimental pretest-posttest design was used wi
th a convenience sample of 10 undergraduate occupational therapy senio
rs. All participants (a) acquired the thinking frame of clinical reaso
ning concepts through explicit instruction and (b) practiced that thin
king frame with an external aid-the Clinical Reasoning Care Study Form
at. The accuracy of participants' definitions of clinical reasoning co
ncepts before and after this learning experience were examined to asse
ss their acquisition of the thinking frame. The content of clinical re
asoning case studies were examined to assess students' application of
the thinking frame to clinical situations. Results. Wilcoxon signed ra
nk tests done on presemester and postsemester definitions ratings indi
cated that the latter were rated significantly higher than the former
for (a) narrative reasoning(p = .008), (b) procedural reasoning(p = .0
05), (c) interactive reasoning(p = .006), (d) pragmatic reasoning(p =
.008), and (e) conditional reasoning(p = .01). The content of particip
ants' clinical reasoning case studies indicated that they were able to
apply clinical reasoning concepts. Conclusion. The results suggest th
at using a clinical reasoning thinking frame to organize clinical obse
rvations is an effective way to help entry-level occupational therapy
students learn and apply clinical reasoning concepts.
