Evolution, Natural Selection and Speciation
Used this activity? Share your experiences and modifications
In this out of class tutorial, students explore several examples of natural selection and speciation. Each example contains interactive simulations that force students to apply concepts to solve problems. Additional questions give students formative assessment and allow the students to see if they need to repeat any units.
Students completing this activity should be able to apply concepts on evolution, natural selection and speciation to specific biological examples.
Students should analyze data and apply it to their model of how natural selection and speciation work.
Context for Use
This exercise is designed as an out of class tutorial that will require students 30 minutes to complete. It is broken into two sections, Natural Selection and Speciation. Students should have a good understanding of both concepts before beginning the exercise.
Description and Teaching Materials
This exercise incorporates two tutorials, one on Natural Selection and the other on Speciation. Each also contains a word file with specific questions the students should address, and a separate file with a multiple choice quiz.

Teaching Notes and Tips
This activity is designed to be used by students out of class after a lecture on evolution. There is a combination of text based questions and interactive simulations with formative assessment to give students feedback on their progress. Quiz questions are also available to either assess student understanding, or give them more feedback as they learn the material. We put the quizzes on-line and used them as a way to be sure the students had gone through the tutorial on their own time out of class.
The tutorials contain formative assessment tools for the students to monitor and judge their own understanding of the material.
Summative short answer questions are integrated into the exercise, and can be used by students to identify key concepts in the tutorial. They can als be turned into the instructor and used for formal short answer assessment of student understanding.
Multiple choice quizzes are also attached which could be used by students for review, as a quiz, or integrated into an exam.
