Measure, Then Show: Grasping Human Evolution Through an Inquiry-Based, Data-driven Hominin Skulls Lab

Area of Science:

• Paleoanthropology
• Evolutionary Biology
• Science Education

Background:

• High school students often struggle with understanding and accepting the theory of evolution, particularly human evolution.
• A lack of teacher preparedness to present fossil evidence contributes to this comprehension gap.

Purpose of the Study:

• To assess the effectiveness of a novel inquiry-based paleoanthropology lab designed to teach human evolution to high school students.
• To evaluate student engagement and learning outcomes using hands-on methods with hominin skull replicas.

Main Methods:

• An inquiry-based lab, "Be a Paleoanthropologist for a Day," was implemented in 11 biology classes across 7 schools.
• Students measured three variables on a dozen hominin skull replicas, analyzed findings, and discussed their observations.

Main Results:

• Teachers unanimously found the lab to be an excellent pedagogical method for teaching human evolution.
• The lab transformed facts into data, information into knowledge, and knowledge into acceptance, empowering students in the scientific process.
• The hands-on format was accessible, engaging students' cognitive, psychomotor, and affective learning domains, fostering higher-order thinking skills.

Conclusions:

• The inquiry-based lab significantly improved students' understanding and acceptance of human evolution.
• The lab provided a formative experience with high retention and epistemic depth, suggesting its value in science education.
• Further research is recommended to quantify the long-term effects of this pedagogical approach.
