Active learning leads to Qs...
Learning Objective
Students will demonstrate understanding of evolution by natural selection.
Questions we asked...What are the learning challenges for students?
Why are students challenged with this topic?
What do we know?
What do we need to know?
•Changes in a population occur through a gradual change in individual members of a population.
•New traits in species are developed in response to need.
•All members of a population are genetically equivalent, variation and fitness are not considered.
•Traits acquired during an individual’s lifetime will be inherited by offspring.
Anderson et al 2002.
Alternative Conceptions: Natural Selection
(AAAS 1999)
Dino/Tree extended responseExplain the changes that occurred in the tree and animal. Use your current understanding of evolution by natural selection.
• Individual AssignmentMake a new concept map demonstrating your understanding of natural selection using the following concepts.
genetic variation evolution species population natural selection artificial selection selective agent

Research Question: Do concept maps facilitate students’
learning about evolution?
• Initial hypothesis: Learning gains are higher for students who use C-maps than for students who do not use C-maps.
• What is wrong with that hypothesis from a research design perspective?
• Discuss in groups. One reporter from each group.
Research Question: Do concept maps facilitate students’
learning about evolution?
Revised hypothesis: Learning gains are higher for students who use C-maps than students who write multiple representations for the same concepts.

Your Group’s Job
Record on a large flip chart:Time 15 minutes - Group report out.
1. Use the learning objective and assessments from your teachable unit/tidbit.2. Develop a research question or hypothesis to test.3. Illustrate the research design.4. Draw or represent one predicted outcome.
