Development of a Safe, Scalable, Course-Based Undergraduate Research Experience for Analytical Chemistry: The μCURE...

Area of Science:

• Analytical Chemistry
• Chemical Education
• Biomedical Engineering

Background:

• Course-based undergraduate research experiences (CUREs) foster student learning and self-efficacy.
• Adapting established assays to new formats like microfluidic paper analytical devices (μPADs) presents unique pedagogical challenges.
• A networked, multi-institutional approach can broaden access to authentic research experiences.

Purpose of the Study:

• To design and implement a networked CURE for analytical chemistry courses.
• To focus the CURE on the process of adapting solution-phase colorimetric assays into μPAD assays.
• To develop and assess scaffolded learning outcomes related to scientific inquiry and collaboration.

Main Methods:

• Utilized backward design to establish five learning outcomes.
• Students conducted literature searches to identify assays for adaptation.
• Implemented a 3-5 week laboratory module with weekly data evaluation and experimental planning.
• Assessed student work using rubrics from the Enhancing Learning by Improving Process Skills in STEM (ELIPSS) Project.

Main Results:

• Student artifacts demonstrated partial to full attainment of learning outcomes.
• The project successfully guided students through adapting assays to μPADs.
• A networked CURE model facilitated collaborative learning across institutions.

Conclusions:

• The developed CURE effectively enhances students' scientific process skills.
• Adapting assays to μPADs provides a valuable, hands-on research experience.
• Networked CUREs are a viable model for delivering authentic research opportunities in STEM education.
