Making Thinking Visible: Behavior over Time Graphs
A Behavior over Time Graph (or BoTG) is a simple line graph that shows a pattern of change over time – it shows how something increases and decreases as time passes. This foundational Systems Tool is instrumental in modeling and understanding many systems. By teaching how to create, use, and understand BoTGs teachers can help students understand concepts (simple and complex) in a more complete and robust way. The following five articles and curriculum provide a gateway to using this powerful tool in the classroom.
Three Things to Remember About Behavior-over-Time Graphs by Alan Ticotsky BOTGs are designed to represent our thinking. All BOTG graphs allow our 'mental models' to take a visual form so we can share them, or analyze them ourselves. Alan Ticotsky presents three insights which will help utilize BOTGs effectively.
Tuck Everlasting: System Dynamics, Literature, and Living Forever Carolyn Platt, Rob Quaden, & Debra Lyneis In this lesson, students use system dynamics tools to explore themes in the novel "Tuck Everlasting," by Natalie Babbitt. Students use behavior over time graphs and a simple system dynamics computer model to discuss their opinions on the story's major themes.
