The effect size of formative assessment is one of the highest of any instructional practices for student achievement gains. However, there is complexity to reaching these effect sizes. This product is Part II of a three part continuum of the critical practices of formative assessment; a continuum of planning, delivery and follow-up. This product features Part II of the continuum - the most critical piece – its delivery during the moment of teaching. Part II lays out in an easily read table the critical behaviors of what formative assessment looks like and sounds like for teachers and students in the classroom while instruction is being delivered. It describes these behaviors in detail when being delivered under three conditions – the ideal, the acceptable and the unacceptable, e.g. what does the delivery of instruction look and sound like when taught ideally, acceptably or unacceptably. Because the product focuses on behavior it is very practical, relevant and easily understood. The purchaser may also like Part I – the planning of formative assessment prior to instruction and Part III the follow-up to formative assessment which addresses next steps.
