Making thoughtful decisions when leading activities is an important part of being a good instructor. But, we recommend that the first few times through, you lead the activity as written, especially if you’re new to this style of instruction. These activities have been thoughtfully planned and written, and the specific questions, statements, and sequence of steps have been rigorously tested by field instructors. Leading the activity as written will help you get a sense of what the activity is all about. Once you’ve led the activity a few times, it’s fine- and even desirable- to make small, thoughtful changes in how you present the activity to best meet the needs of your students.
Of course, there are minor adjustments to an activity you may need to make to, for example, accommodate for your site, time constraints, or weather conditions. When making such changes, be sure to read the Teaching Notes included in the sidebars throughout the write-up and in the Instructor Support section- many activities have notes that explain the rationale behind certain steps or language, or notes on changes to the activities that have been found to be particularly effective or ineffective in field testing.
