Mentorship plays an important role in the experiences of undergraduate researchers, and students may interact with multiple potential mentors in laboratory settings. Using qualitative methods, we explored the relationships between undergraduate students engaged in research and their mentors in faculty-led laboratories, with particular attention to…

Hands-on, inquiry-based laboratory activities are excellent opportunities to introduce first-year undergraduate students to the lab environment and to catalyze new interest in topics they may not yet know or be as enthusiastic about studying. We describe a multisession introductory laboratory activity that couples the research areas of medicinal…

The authors of this article applied the determination of phenolic and flavonoid content in small berries to create a didactic cycle based on student-centered active learning (SCAL) in which students actively participated in the topic while studying and profile-forming as future biology and chemistry teachers. The fundamental part of the proposed…

This project involves students in a course-based undergraduate research experience (CURE) as part of the traditional introductory biology laboratory course. Recently, research has shown that student engagement in authentic research has significant positive impacts on students, such as development of science literacy and reasoning skills. Being…

Increasingly, students training in the biological sciences depend on a proper grounding in biological statistics, data science and experimental design. As biological datasets increase in size and complexity, transparent data management and analytical methods are essential skills for undergraduate biologists. We propose that using the software R…

Growing evidence has come to suggest that model-based inquiry can improve student learning outcomes and attitudes toward STEM in the biological sciences and beyond. In our introductory biology laboratory course that focuses on cellular and molecular biology, we introduced model-based inquiry (MBI) labs to create a more student-focused course that…

Although research and new technologies have introduced different ways of observing microorganisms, including scanning and electron microscopy, these methods are expensive and require equipment that is typically not found in a middle school classroom. The transmission-through-dye technique (TTD; Gregg et al., 2010), a new optical microscopy method…

A lesson plan on the phylum Tardigrada is presented in a storytelling workbook that introduces the evolutionary concepts of adaptive radiation, speciation, divergence, and "tree-thinking" through narrative, transitional art, contemplative coloring, and data searches, which can be enhanced with microscopy wet labs. Students gain insight…

It has been noted that undergraduate project-based laboratories lead to increased interest in scientific research and student understanding of biological concepts. We created a novel, inquiry-based, multiweek genetics research project studying Ptpmeg, for the Introductory Biology Laboratory course at Brandeis University. Ptpmeg is a protein…

Biology labs often make use of student teams. However, some students resist working in teams, often based on poor experiences. Although instructors sometimes struggle with student teams, effective teams in biology labs are achievable. We increased student learning and satisfaction when working in research teams by (1) including in the syllabus a…

Many biology educators at the undergraduate level are revamping their laboratory curricula to incorporate inquiry-based research experiences so that students can directly participate in the process of science and improve their scientific reasoning skills. Slugs are an ideal organism for use in such a student-directed, hypothesis-driven experience.…

The AAAS Vision and Change report (2011) recommends incorporating student research experiences into the biology curriculum at the undergraduate level. This article describes, in detail, how "Zea mays" (corn) cultivars were used as a model for a hypothesis-driven short-term research project in an introductory biology course at a small…

Ocean acidification, a product of CO[subscript 2] absorption by the world's oceans, is largely driven by the anthropogenic combustion of fossil fuels and has already lowered the pH of marine ecosystems. Organisms with calcium carbonate shells and skeletons are especially susceptible to increasing environmental acidity due to reduction in the…

We describe an activity that uses cards to simulate evolution. The mechanism of the evolutionary pressure in the simulation is clearly indicated for the students. This simulation is useful for allowing student experimentation by varying conditions.

This article presents a tangible model used to help students tackle some misconceptions about enzyme actions, particularly the induced-fit model, enzyme-substrate complementarity, and enzyme inhibition. The model can simulate how substrates induce a change in the shape of the active site and the role of attraction force during enzyme-substrate…
