Inquiry-based learning: inflammation as a model to teach molecular techniques for assessing gene expression.

Area of Science:

• Molecular Biology
• Immunology
• Biochemistry

Background:

• Scientific inquiry is central to biological research.
• Understanding inflammation in macrophages is crucial for disease research.
• Inquiry-based learning enhances scientific skill acquisition.

Purpose of the Study:

• To simulate the scientific process for students using inflammation as a model.
• To teach students hypothesis development, experimental design, and data interpretation.
• To assess student learning of biological concepts and research methodologies.

Main Methods:

• Students utilized molecular biology techniques including transfection, luciferase reporter assay, immunoblot, fluorescence microscopy, ELISA, and quantitative PCR.
• Macrophage cells were treated with various mediators to assess inflammatory responses.
• Literature searches were conducted to inform hypothesis generation regarding mediator effects on inflammation.

Main Results:

• Over 95% of students successfully achieved learning objectives across three cohorts (n=85).
• Students developed quantitative and qualitative reasoning skills through data analysis.
• Successful completion of post-lab worksheets and scientific poster presentations demonstrated learning.

Conclusions:

• The inquiry-based laboratory module effectively teaches scientific methodology and biological concepts.
• Students gain practical experience in molecular biology techniques and data interpretation.
• The module successfully prepares students for biological research by fostering critical thinking and practical skills.
