Attack of the killer fungus: a hypothesis-driven lab module

Area of Science:

• Ecology
• Mycology
• Undergraduate Education

Background:

• Discovery-driven laboratory experiments enhance student learning and critical thinking.
• Undergraduate science curricula can benefit from modules promoting active participation in the scientific method.

Purpose of the Study:

• To develop and assess a laboratory module focused on worm capture by nematophagous fungi.
• To improve students' understanding of fungal predation mechanisms and ecological roles.
• To achieve specific learning goals, including hypothesis development and literature analysis.

Main Methods:

• A ten-week laboratory module was implemented for undergraduate science majors.
• Students conducted experiments on the regulation of worm capture by soil-dwelling fungi.
• Data generation and analysis were performed, comparing novel findings with published literature.

Main Results:

• Students successfully generated novel experimental data.
• Student performance indicated learning gains through pre- and post-module assessments, exams, and reports.
• The module facilitated active engagement with the scientific method.

Conclusions:

• The developed lab module effectively enhances student understanding of fungal predation and ecological processes.
• This discovery-based approach fosters critical thinking and practical scientific skills in undergraduates.
• The module contributes to both student learning and the scientific understanding of ecologically relevant organisms.
