The design phase also involves planning how to manage the flow of students through the various lesson activities. During the development phase, all supporting materials are developed. These could include job aids to assist the students in completing a database, a written problem statement that has spaces for students to record the results of working through the critical thinking process, or a prototype of the final student product to assure lesson integrity.
Students actually work through the lesson during the implementation phase.
This is the time that the teacher engages in the role of being a facilitator. During this time, the teacher also must manage the flow of activities required to complete the lesson. Some of this management occurs through established classroom practices, for example placing a cup on the computer monitor when a student needs technical assistance, or assigning one student per group as technical assistant. Other management issues may be specific for each lesson. For example, student groups may need to rotate to an outside garden to collect soil samples, then move to the science table to gather various data on the sample, and from there rotate to the computers to enter the data and create a report.
