Teacher Guides

Each teacher guide contains background content, prerequisites and learning outcomes. In addition, there are helpful notes about the data, and scientific and mathematical processes used. Three sections may be especially useful for you if you are new to teaching astronomy:

• Background contains an overview of the topic and links to an online textbook and other resources.
• Common Student Questions highlights typical student questions with (teacher) answers.
• Common Student Ideas addresses preconceptions, misconceptions, incomplete learning, and learning confusions, along with ways to redirect students toward building a conceptual model that achieves the learning outcomes.

Each guide provides an estimate of the time students will need to complete the online investigation. This time does not account for additions such as formative assessment breaks, class discussions, engagement activities such as a video or phenomenon, or completing a summative assessment.
