Purpose: To determine the impact of a training program on the ability of preservice teachers (PTs) to negotiate with their students while teaching through the skill themes approach during an early field experience. Method: Participants were 11 PTs who were given specific training on how to negotiate with their students. Data on their ability to negotiate were collected during the early field experience with six qualitative techniques (journaling, document analysis, participant observation, and formal, informal, and stimulated recall interviews) and were analyzed using standard interpretive techniques. Findings: The training program was effective. Patterns of negotiation observed for both PTs and students improved as the PTs' skill themes units progressed. The volume of positive negotiations increased and the volume of negative negotiations decreased. Key training program components were lecture/discussions, film, journaling, and role playing. Conclusions: Training PTs to negotiate can help them improve their teaching through the skill themes approach. Ability to negotiate may distinguish between effective and ineffective PTs who otherwise have similar pedagogical skills.
