Table 3 Activity timeline for instructor

From: Making evolution stick: using sticky notes to teach the mechanisms of evolutionary change

Activity Description Approximate time (min)
Before class
 Instructor prep Review concepts and modify activity as needed. Prepare handouts. Procure sticky notes (four colors, with ~ 30 notes of each color per group) 60–120
 Student prep Read assigned section of text. Write short answers to pre-activity discussion questions (Table 2B) 15–30
During class
 Warm-up discussion Whole-class discussion on pre-class questions (Table 2B) 10
 Introduce activity Instructor describes sticky note species and demonstrates mechanism of founder effect 5
 Complete activity in small groups Spend about 6 min enacting each mechanism; each student also completes individual handout (Additional file 1) 45
 Wrap-up and group rearrangement During this time, students can walk around to examine other groups’ populations 5
 Synthesis discussion Whole-class discussion to address misconceptions (Table 2C) and synthesis questions (Table 2D) 10
After class
 Homework Complete worksheet that reviews material and introduces allele frequency calculations (Additional file 2) 20–45
 Review See extensions: guess the mechanism, apply multiple mechanisms 15–30
Variations
 Think/pair/share A time-saving alternative to small-group work. The entire class focuses on one population. Student pairs use the think/pair/share method to follow along on their individual handout (Additional file 1), which student volunteers coming to the front of the room to demonstrate each mechanism 20–30
 Jigsaw method Activity will cover four mechanism and be divided into two parts: students should spend about 10 min in their expert groups and 20 min in their novice groups (spending about 5 min per mechanism); 10 min are built-in for rearranging groups 40
