Participation trajectories, transaction structures, and organization of natural pedagogical conversations of high school students' internship in science laboratories

Many science educators encourage student experiences of "authentic" science by means of student participation in science-related workplaces. Little research however has done to investigate how "teaching" naturally occurs in such settings, where scientists/technicians normally do not have pedagogical training and generally do not have time (or value) receiving such training. This study examines how laboratory members without a pedagogical background or experience in teaching engage high school students during their internship experiences. Drawing on conversation analysis, we analyze the minute-by-minute transactions that occurred while a group of 13 students participated in a leading environmental science laboratory. We found that the participation structures are based on demonstration-practice-connect (D-P-C) phases that continually recur in the process of "doing" science. Concerning the transactional structures, we identified two basic patterns- Initiate-Clarify-Reply (I-C-R) and Initiate-Reply-Clarify-Reply (I-R-C-R)- that not only differed from traditional I-R-E patterns previously observed in science classrooms, but also could be combined to constitute more complex patterns. With respect to the organization of natural pedagogical conversations, we found that there are not only of preferred and dispreferred modes of responding but also ambiguous dispreferred modes; and the formulating organization not only includes self-formulating (saying what one is doing at the moment as in "I am going to ask you a question") but also other-formulating. We discuss possible implications for the training of personnel involved during high school students' internship experiences in scientific workplaces and for classroom teaching.
