BIO 123 – Biological Science II Course Context: Descent with Modification unit

Learning Objective

Taxonomy Level/Category

Learning Activities

Formative Assessment

Summative Assessment

Compare and contrast Lamarck’s hypothesis of inheritance of acquired characteristics and Darwin’s theory of descent with modification

Analysis • Textbook Reading

• In-class group work to prepare for:

• Mock debate

• Mastering Bio Reading quiz

• Practice exam problems / Weekly quiz

• In-class exam

Learning Activities• Students read text before lecture• Students work in small groups to prepare for mock debate –

group works on either Lamarck or Darwin

• Student groups ‘debate’ the POV by sharing their example and how that example supports their hypotheses

Lamarck groups:• Define characters• Describe the role of the environment on

characters• Explain Lamarck’s hypothesis of use and

disuse• Explain Lamarck’s hypothesis of

acquired characteristics• Compose an example that supports

Lamarck’s hypotheses

Darwin groups:• Define characters• Describe the role of the environment on

adaptation• Explain Darwin’s hypothesis of natural

selection• Explain Lamarck’s hypothesis of descent

with modification• Compose an example that supports

Darwin’s hypotheses

Formative Assessments• Students take quiz on the reading on

Mastering Biology before lecture• Mock debate• Students given practice exam questions

through weekly quiz– Online quiz, can retake once

Summative Assessments• In-class exam• How would vestigial traits be explained if evolution occurred via inheritance of acquired

characters as proposed by Lamarck?– 2.33 A) as the product of natural selection– 62.79 B) as a change in an individual's phenotype in response to an environmental challenge– 27.91 C) as a change in a population's phenotype in response to an environmental challenge– 6.98 D) as the product of instantaneous creation by a supernatural being

• According to Darwin, adaptations are ______ characters that enhance survival and reproduction in _________.– 67.44 A) inherited; a specific environment.– 0.00 B) inherited; all environments.– 30.23 C) acquired; a specific environment.– 2.33 D) acquired; all environments.

• A dog trained to guide the blind has offspring. None of the offspring can guide the blind. Does this situation support or refute Lamarck’s hypothesis of inheritance of acquired characters? Explain why or why not.

Timeline

• Most likely changing jobs within the next few weeks

• Once I have a course or workshop to design, I will need to develop new learning goals, activities, and assessments
