Bioinformatics is a BLAST: Engaging First-Year Biology Students on Campus Biodiversity Using DNA Barcoding

In order to introduce students to the concept of molecular diversity, we developed a short, engaging online lesson using basic bioinformatics techniques. Students were introduced to basic bioinformatics while learning about local on-campus species diversity by 1) identifying species based on a given sequence (performing Basic Local Alignment Search Tool [BLAST] analysis) and 2) researching and documenting the natural history of each species identified in a concise write-up. To assess the student’s perception of this lesson, we surveyed students using a Likert scale and asking them to elaborate in written reflection on this activity. When combined, student responses indicated that 94% of students agreed this lesson helped them understand DNA barcoding and how it is used to identify species. The majority of students, 89.5%, reported they enjoyed the lesson and mainly provided positive feedback, including “It really opened my eyes to different species on campus by looking at DNA sequences”, “I loved searching information and discovering all this new information from a DNA sequence”, and finally, “the database was fun to navigate and identifying species felt like a cool puzzle.” Our results indicate this lesson both engaged and informed students on the use of DNA barcoding as a tool to identify local species biodiversity.

Biodiversity Show and Tell: An Accessible Activity to Encourage Students to Explore the Tree of Life

An appreciation of organismal diversity is a requirement for understanding evolution and ecology, and can serve as a source of amazement and wonder that inspires students to enjoy biology. However, biodiversity can be a challenging subject to teach: it often turns into a procession of facts to memorize and a disorienting list of Latin names. To help engage students in this topic, we developed an activity in which each student contributes to a class "biodiversity tour" of strange and intriguing species. Students in our large-enrollment introductory biology course use the Internet to find a species that interests them and that they think will interest their peers. They research their species and complete a worksheet to report their findings. Then they meet in discussion sections of ~32 students (in person or online) where each student gives a brief presentation about their species using a slide they have prepared, producing a lively, crowd-sourced, rapid-fire nature documentary. The performance for their peers motivates students to find the strangest species possible. Students overwhelmingly reported that this activity taught them something new about life on Earth and increased their interest in our planet's species. Many students also reported that this activity caused them to talk to someone about biology outside of the class and increased their personal connection to the natural world, suggesting that it helped them see the relevance of biology to their everyday lives. This simple activity can enrich an introductory biology course of almost any size.
