| Abstract: | The purposes of this study were to understand the nature of discourse in terms of knowledge types and cognitive process, source
of utterances (student or teacher), and time use in microcomputer-based labs (MBL) and verification type labs (VTL) and to
gain an understanding of the role of MBL in promoting mathematization. The study was conducted in 2 grade 11 classes in which
students studied Hooke’s law and Newton’s second law of motion using MBL during 1 year while a different group of students
studied the same topics with the same physics teacher using a VTL approach. All sessions were videotaped, transcribed and
coded using a taxonomy developed by DeVito & Grotzer (2005). In addition, evidence to support each of the 5 steps of mathematization was sought from the actions of the teachers and
their discourse with the students. Results showed that conceptual knowledge type utterances were significantly more frequent
in MBL sessions, cognitive processes of remembering and understanding were significantly more frequent in the MBL sessions,
students spent most of their time analyzing the graphs in the MBL sessions, and MBL has a potential to promote mathematization
in favorable instructional environments in physics laboratory classes. |
