DNA Barcoding for an Undergraduate Class.

Area of Science:

• Molecular Biology
• Genetics
• Bioinformatics

Background:

• DNA techniques are fundamental to undergraduate biology and biochemistry curricula.
• Inquiry-based learning enhances student comprehension and engagement.
• Traditional curricula often present DNA techniques in isolation.

Purpose of the Study:

• To present DNA barcoding as an effective pedagogical tool for undergraduate and advanced high school settings.
• To demonstrate how DNA barcoding can integrate essential molecular biology techniques into a cohesive student project.
• To provide a framework for instructors to implement DNA barcoding in their classrooms.

Main Methods:

• Implementing a DNA barcoding project within a two- or three-week timeframe.
• Integrating core molecular biology techniques: DNA isolation, purification, Polymerase Chain Reaction (PCR), and basic BLAST searches.
• Facilitating group-based student projects, allowing for self-designed research components.

Main Results:

• Successful integration of essential DNA techniques into an inquiry-based learning module.
• Students gain practical research experience through hands-on DNA barcoding projects.
• The curriculum is adaptable for both undergraduate college and advanced high school levels.

Conclusions:

• DNA barcoding offers a valuable, integrated approach to teaching fundamental molecular biology techniques.
• This method enhances student learning through an inquiry-based, research-oriented experience.
• The described approach provides a practical guide for educators to incorporate DNA barcoding into science curricula.
