The Design, Implementation, and Assessment of an Undergraduate Neurobiology Course using a Project-Based Approach.

ABSTRACT: Project-based learning (PBL) is a student-centered approach that allows students to build on prior knowledge and address relevant problems while working on challenging projects. PBL is well-suited to undergraduate neuroscience courses because students are often interested in learning about diseased states of the nervous system, but can be discouraged by having to learn the chemical and cellular mechanisms underlying pathologies in a lecture-based learning environment. PBL provides students with a significant learning experience that excites them and can help them learn challenging content. Drawing from the recommendations of multiple STEM education reform efforts, I examined the effectiveness of using PBL in an undergraduate neurobiology course to provide students with significant and engaging learning experiences. Students were grouped into teams using a guild system and completed three substantial projects consisting of team-authored research papers and poster presentations. Each project was designed to address fundamental neuroscience concepts using a real-world problem. By the end of the course, students were more confident in their understanding of neuroscience and had greater understanding of neuroscience concepts. Student attitudes toward working on projects or working as a member of team did not change but remained positive throughout course. Taken together, these results suggest that PBL can be an effective way to actively engage students while allowing them to learn, integrate and communicate core neuroscience concepts.

Project description:Course-based undergraduate research experiences (CUREs) are an effective means of transforming the learning and teaching of science by involving students in the scientific process. The potential importance of the microbiome in shaping both environmental health and disease makes investigations of microbiomes an excellent teaching tool for undergraduate microbiology. Here, we present a CURE based on the microbiome of the bean beetle (Callosobruchus maculatus), a model system for undergraduate laboratory education. Despite the extensive research literature on bean beetles, little is known about their microbiome, making them an ideal system for a discovery-based CURE. In the CURE, students acquire microbiological technical skills by characterizing both culturable and unculturable members of the beetle gut-microbial community. Students plate beetle gut homogenates on different media, describe the colonies that are formed to estimate taxonomic diversity, extract DNA from colonies of interest, PCR amplify the16S rRNA gene for Sanger sequencing, and use the NCBI-nBLAST database to taxonomically classify sequences. Additionally, students extract total DNA from beetle gut homogenates for high-throughput paired-end sequencing and perform bioinformatic and statistical analyses of bacterial communities using a combination of open-access data processing software. Each activity allows students to engage with studies of microbiomes in a real-world context, to apply concepts and laboratory techniques to investigate either student or faculty-driven research questions, and to gain valuable experiences working with large high-throughput datasets. The CURE is designed such that it can be implemented over either 6-weeks (half semester) or 12-weeks (full semester), allowing for flexibility within the curriculum. Furthermore, student-generated data from the CURE (including bacterial colony phenotypic data, full-length 16S rRNA gene sequences from cultured isolates, and bacterial community sequences from gut homogenates) has been compiled in a continuously curated open-access database on the Bean Beetle Microbiome Project website, facilitating the generation of broader research questions across laboratory classrooms.
