Trails to Research: an Inquiry-Based Course Using Zebrafish To Provide Research Experience to Tribal College Students

Area of Science:

• Developmental Biology
• Toxicology
• Undergraduate Education

Background:

• Embryonic development is an engaging topic for introducing students to experimental science.
• Zebrafish embryos are ideal model organisms for classroom research due to rapid development and ease of manipulation.

Purpose of the Study:

• To introduce undergraduate students with limited research experience to life science research.
• To develop an inquiry-based course focused on experimental design and data analysis using zebrafish embryos.

Main Methods:

• A 5-day intensive "Trails to Research" course was designed for 2-year college undergraduates.
• Students participated in modules covering developmental biology, toxicology, experimental design, zebrafish embryo manipulation, and data presentation.
• Students designed and conducted experiments using known teratogens and selected substances on zebrafish embryos.

Main Results:

• Significant student learning was observed in experimental design.
• Students demonstrated improved skills in working with model systems and zebrafish embryos.
• Students enhanced their abilities in using laboratory equipment and presenting experimental results.

Conclusions:

• The "Trails to Research" course effectively enhances undergraduate students' understanding and practical skills in experimental science.
• Zebrafish serve as a valuable model organism for teaching developmental biology and toxicology in an undergraduate setting.
• Inquiry-based learning approaches are beneficial for developing research competencies in novice students.
