3. Results and Discussion
The research described here constitutes a small step in the direction of developing additional learning units within
the traditional curriculum. Current research being undertaken by the authors is exploring possible additional
methods of CT evaluation, including: the CCTDI scale (Facion, 1992), questionnaires employing various
approaches, and a comprehensive test composed for future research. The general educational implications of this
research suggest that we can and should lever the intellectual development of the student beyond the technical
content of the course, by creating learning environments that foster CT, and which will, in turn, encourage the
student to investigate the issue at hand, evaluate the information and react to it as a critical thinker. It is important to
note that, in addition to the skills mentioned above, in the course of this lesson the students also gained intellectual
skills such as conceptual thinking and developed a class culture (climate) that fostered CT. Figures 1 and 2 show the
sub-tests of the results of the CCDTI test (Fig. 1,2).
