Joyce and Showers argue that effective teacher professional development requires more than just knowledge and skill acquisition; it must also help teachers become effective learners. They propose a model of training that includes four components: developing knowledge through theory, demonstrating skills, practicing skills, and peer coaching. These components are essential for transferring new knowledge into classroom practice, especially for complex or new tasks. Peer coaching is particularly important as it supports the transfer of training and fosters a culture of collaboration and experimentation. The authors emphasize that training should be designed to achieve specific outcomes, such as knowledge, attitude changes, skill development, or transfer of training. They also stress the importance of organizational support, strong leadership, and the need for trainers to consider the target audience and desired results. Coaching is a key component of training, as it helps teachers implement new strategies and adapt them to their contexts. The authors found that coached teachers were more likely to use new strategies effectively, retain skills, and explain them to students. However, they also note that feedback in coaching can become evaluative and time-consuming, so they have removed it from their model. Instead, they suggest that teachers can act as coaches when observing each other. The authors conclude that while peer coaching is challenging, it is worth the effort as it enhances teacher collaboration and student learning. They recommend that training should include time for peer coaching, collaborative planning, and monitoring the impact of new initiatives on student achievement. Overall, the authors emphasize that effective training is multi-faceted and requires careful design, organizational support, and a focus on both knowledge and learning skills.Joyce and Showers argue that effective teacher professional development requires more than just knowledge and skill acquisition; it must also help teachers become effective learners.
