Cj. Bonk et al., Web-based case conferencing for preservice teacher education: Electronic discourse from the field, J EDUC COMP, 19(3), 1998, pp. 269-306
The purpose of this study was to foster preservice-teacher learning of educ
ational psychology by creating a Web-based learning community using actual
case situations these future teachers had experienced during their field ob
servations. In this study, 146 undergraduate educational psychology student
s were randomly assigned to two different electronic conferencing groups wh
ere they generated teaching vignettes related to their early field experien
ces and reacted to the cases of their peers. As a counterbalanced research
design, half of these students received heavy scaffolding (HS) during the f
irst three weeks of electronic case conferencing and weak scaffolding (WS)
during the following three weeks; the other half received the opposite. Wit
hin these conferences, there were a total of 229 cases generated for discus
sion with 1,320 replies. While there were 20 percent more postings in the f
irst three weeks, the cases and responses generated in the second three wee
ks were lengthier Importantly, HS fostered 18 percent more student cases th
an WS, though these were of significantly lower quality than the WS cases.
A coding of dialogue transcripts from fifty-eight randomly selected cases i
ndicated that peer feedback was extremely conversational and opinionated, w
hereas instructor mentoring was focused on high level questioning course re
lated advice, and case specific feedback.
