"Our
study was guided by the following major research question: What are the
similarities and differences in teacher talk moves that occurred within an
engineering design-based science unit enacted by two teachers? Through
qualitative and quantitative approaches, we found that there were clear
differences in two teachers’ use of questioning strategies and presentation of
new knowledge that affected the level of student involvement in classroom
discourse and the richness and details of student contributions to the
conversations"
PS - Since the teacher that was more positively evaluated was a male probably gender bias also played a role in the evaluation ! I do not even understand why did the authors decide to disclose the gender of the professors.
