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
