"The POE strategy allows students to reflect on their experiences with and understanding of a subject before making a prediction about the outcome of an experiment and discussing the prediction with classmates. Following up this discussion with observations and then scientific explanations of the outcome gives students a more in-depth understanding of the subject at hand. Lessons include worksheets, scientific explanations of the concepts being studied, summaries of student responses during the field tests, synopses of research findings, and lists of necessary materials." -- Publisher Contents:
