Improving the quality of learning in high schools and preparing young for thinking skills disposition is needed to
promote the quality of teaching and results of several studies has shown usefulness of collaborative method in
various fields.
Therefore, in this study we examined the effect of collaborative method on critical thinking disposition in high school students.
Results indicated the influence of collaborative method of critical think disposition.
These findings are consistent with Shabani (1999), Hosseini (2009) and Wiggs (2008) and are disparate
with results of Johnson, Archibald & Tenenbaum (2010).
The deduction of these finding can be said to be that discussions and conversations that occur during classroom activities for learners with applied collaborative method,promotes students inner motivation for improving intellectual skills.
In other words, this method has extra features compared with traditional methods such as discussion environment, social interactions and opportunities of criticism which increases students' disposition toward critical thinking.
The next result was showed that collaborative method had affected on the creativity component but has been affectless on the other two components which are innovation and commitment. Regarding the influencing of collaborative method on creativity it can be inferred that using collaborative method increases joy of learning in classroom,
so we can provide contexts for detection of group creativity in students.
One of this study's limitations was small sample size because of executing limits
so generalization of results to other groups and girl students is not possible.
In general, results of this study, showed influence of collaborative method on students' critical thinking disposition. Therefore, given to this study's results and its matching with other researches' results in this field considering implementation of collaborative method in curriculum and educational systems can be emphasized. In summary,
it can be said that the more the teacher creates opportunities for interaction between learners, the more opportunities for criticism in students' activities and various issues are created and it provides a more suitable context for students' critical thinking disposition.
Therefore,considering opportunities that collaborative learning compared with individual environment provides, of
this of this method by teachers in educational systems is suggested.
