Even though this study showed that CCM as a teaching strategy had no significant effect on
attitudes toward chemistry as a subject, it cannot be ruled out that CCM would have an effect,
if other measures of attitudes were employed or if a different topics was used. Although
attempts were made to ensure that the learning environment of all the students involved in the
study was similar as possible; it is important to appreciate the possibility that attitudes toward
chemistry can be shaped by non-school influences (e.g., media, peers, parents). This
possibility is plausible especially with respect to topics perceived to be abstract and difficult
such as “mole concept” dealt with in the present study. Studies investigating effect of various
instructional methods have suggested use of mixed methods approach for concurrent
triangulation and corroboration of findings within a single investigation (Cresswell, Clark,
Gutmann, & Hanson, 2003; Clary & Wandersee (2007). The use of quantitative methods of
data collection alone in this study might have been limiting, bearing in mind the multidimensional
aspect of attitude, a psychological construct, which has implication for cognitive,
affective as well as behavioral characteristics of the learner
