Nature or Nurture? Heritability in the Classroom

Area of Science:

• Biology Education
• Evolutionary Biology
• Genetics

Background:

• Heritability of traits is crucial for understanding evolution but often taught with limited examples.
• Traditional methods rely on static data, potentially hindering student engagement.

Purpose of the Study:

• To introduce an active-inquiry exercise for estimating heritability in undergraduate biology.
• To enhance student understanding of heritability, data analysis, and the scientific method.

Main Methods:

• Students generate hypotheses about trait inheritance.
• Students collect and analyze personal data to estimate heritability.
• The exercise incorporates instructor guidance and discussion.

Main Results:

• The activity engages students by using their own data.
• It reveals potential biases and misconceptions in heritability estimation.
• Active inquiry fosters deeper learning and critical thinking.

Conclusions:

• This hands-on approach significantly improves understanding of heritability.
• Active-inquiry promotes scientific curiosity and a robust grasp of evolutionary principles.
• The exercise effectively bridges the gap between theoretical concepts and practical application.
