Abstract

Abstract for 2024 ASEE Southeastern Section Conference Problem Based Learning (PBL) or Course-embedded Undergraduate Research Experience (CURE) projects challenge students to problem solve using scientific literature and teamwork while investigating solutions to a real problem. Through scaffolding, students learn how to conduct peer-reviewed literature research, formulate research questions, co-design experiments, collaborate in groups, conduct experimental protocols, troubleshoot lab protocols, and report their findings. This paper discusses a PBL/CURE project introduced to Microbiology students at Dalton State College in Spring 2023. The project begins by discussing global problems including concerns with greenhouse gas, scarcity of crude oil, and human waste management. Students watch an inspirational TED talk presented by NASA’s Jonathan Trent on Energy from floating algae pods. Students explore the topic of algae biodiesel fuel, the potential types of microalgae and how to grow, harvest, and extract lipids for bio-diesel conversion. Student groups explore peer-reviewed literature research on the assigned algal organisms: Nannochloropsis oculata, Porphyridium cruentum, or Chlorella vulgaris. Then, student teams collaborate with the professor and co-design experiments in attempts to obtain the final product which are algal lipids. Students are relatively successful in growing, harvesting, and obtaining dry weight of algae in 10 weeks of the 15-week semester. Due to the insufficient amount of dried algae mass obtained, extracting algal lipids proves to be unmanageable for this project. Students create a written research paper and present the paper in the course symposium: DSC’s Algae Biodiesel Research Symposium. Students complete a post-survey pertaining to their PBL/CURE project experience, and express that this research experience has provided a unique opportunity that they would not have experienced outside this course. This paper shows a model for experiential learning that provides a valuable and enriching research experience for undergraduate students in science lab courses.
