To examine whether deliberative argumentation enhances conceptual understanding more effectively than disputative argumentation when controlling for dialogue content and structure.
Conducted two randomized controlled experiments evaluating understanding of natural selection in undergraduate students.
In Study 1, participants (N = 58) engaged in a chat-based transfer task with a scripted confederate displaying either a deliberative or disputative rhetorical style while holding content constant.
In Study 2, a separate cohort (N = 88) read either a deliberative or disputative dialogue held between two peers.
Deliberative argumentation produced significantly greater conceptual understanding than disputative argumentation across both active discussion and passive reading formats after adjusting for pretest scores.
Participants exposed to deliberative dialogue evaluated their partners and the interaction more favorably than those in disputative conditions.
Deliberative framing increased participants' willingness to revise their original explanations and collaborate on subsequent tasks.
