    ABSTRACT Collaboration and communication are important competencies for undergraduate life science education, as noted in theVision and Change in Undergraduate Biology Educationreport. However, initiating collaboration and communication in the classroom can be an anxiety-inducing experience for many students. In contrast to traditional-style icebreakers, we introduce a course content-focused icebreaker activity that served as a group-forming undertaking on the first day of class. We developed four sets of handouts (icebreaker tickets), each having a common course theme (e.g., microbiology, cell biology, physiological system infections/disorders, virology). Students were randomly provided with a ticket at the beginning of the course, and they worked to establish groups with their peers, based on their own interpretation of the ticket’s content and rationalization of a grouping scheme. Student feedback and engagement data collected from implementation at three independent institutions were largely positive, where students reported the activity to be an effective tool for building a course content-focused community of learners. The icebreaker tickets and instructor’s notes disseminated in this manuscript can be adapted to fit educators’ course goals and help set the tone for the first day of the class and beyond that fosters communication and collaboration among students.

    Winogradsky columns were invented by Sergei Winogradsky in the 1880s and have commonly been used as a microbiology classroom learning tool in K-12 and collegiate education. However, they can be challenging to examine with microscopy. We scaled down Winogradsky columns into nuclear magnetic resonance (NMR) tubes and replaced the natural sediment with a transparent soil substitute toward the goal of observing the microbial growth under a bright-field microscope without column disassembly. Using this “Mini Winnie” approach, students can practice their microscopy skills while observing microbial growth inside the column after only days of incubation on the laboratory windowsill. Overall, we believe that the Mini Winnies provide a simple method for maximizing student engagement while giving them a greater understanding of how microorganisms interact in the environment.

    ABSTRACT Articulating clear and achievable expectations is fundamental to both education and organizational management. In this article, we provide a simple intervention for clarifying expectations–and establishing that these expectations have been understood–which proved beneficial both to community college interns and to their internship mentors in biotech-related undergraduate research experiences. Internship mentors were asked to utilize a simple Expectation Clarity Tool to outline the expectations, success metrics, baseline assessments, and training strategy and support that would be foundational to their intern’s project. These included expectations around conceptual, technical, performance, and professional skills and behaviors. Concurrently, but independently, community college interns were asked to complete the same type of exercise as a way of identifying gaps in their knowledge and understanding of their mentor’s expectations and their internship project. The mentor’s completed Expectation Clarity Tool was then shared with their intern. As a result of completing this relatively simple intervention, the majority of mentors reported that it increased their confidence as a mentor, taught them a new mentoring skill, changed how they will mentor trainees moving forward, and positively impacted their relationship with their trainee. On the intern side, the majority of interns reported that engaging in this intervention, both as an independent exercise and in obtaining their mentor’s completed Expectation Clarity Tool, increased their confidence as an intern and positively impacted the success of their internship.
