Visualizing kinetic processes can be an impediment to student mastery of basic science coursework. To remedy this obstacle, I created an educational program called Biology from Molecules to Embryos^© (BioME), which provides 28 animated lessons for genetics and embryology. To provide access to the international educational community, BioME has been posted as an interactive, open access website. Empirical data demonstrates that BioME is an efficacious educational resource, which elicits positive student perception of its utility. The animated lessons are useful for student self-study. For instructors who choose to display BioME lessons as visual aids for their presentations, explanatory text can be hidden so that it does not compete with the instructors’ verbal explanations. For instructors who would not choose to use premade lessons, downloadable excerpts are provided. These excerpts are short presentations of specific topics that can be incorporated at any point of a lesson according to the instructor’s preference and student needs. To provide opportunities for self-quizzing and to summarize key points, multiple PopUp files are provided for most lessons. To allow students to actively access their mastery of the material and to take advantage of the testing effect, multiple-choice practice questions are also provided with each lesson. The level of these questions ranges from first-order recall to third-order application. The higher order questions promote deep processing by requiring students to deduce answers by actively integrating material within and across lessons. Thus, BioME can help to advance the understanding of biological sciences and promote the usage of animations to present dynamic processes.

This module introduces students who are already familiar with GIS to doing comparative analyses with large-scale community science (often called citizen science) data sets. Students will explore how we can use community science data to examine the spread and distribution of invasive species in different geographic locations. In the final step, students will identify different invasive species and determine if community science data accurately maps the threat these species pose.

Students learn about the importance of good data management and begin to explore QGIS and RStudio for spatial analysis purposes. Students will explore National Land Cover Database raster data and made-up vector point data on both platforms.

This exercise explores circumstances of urban heat islands in the United States using spatial data, including an exploration of heat island solutions.

This module is made up of four concepts. The goal of the first concept is to elicit an understanding of primate relatedness, phylogeny, and how specific characteristics are beneficial for life in an arboreal environment. The next concept explains the overarching trends in hominin evolution and the selective pressures that encouraged their development. Concept three examines specific fossils and the characteristics that are associated with them. This concept serves to provide a timeline of hominin evolution. The final concept encourages students to understand characteristics in the hominin lineage and how they relate to social behaviors. This concept ends by driving home the point that evolution is a dynamic and continual process.

This module examines the complicated co-evolution of Lice, Humans, and Great Apes

Traditionally-trained undergraduate students often lack an understanding of science as an active process that yields the information presented in their textbooks. One result has been a call for more research experiences built into traditional introductory undergraduate courses, now commonly referred to as course-based undergraduate research experiences (CUREs). The laboratory module presented in this paper used an established four-step pedagogical framework to simplify and streamline the development and implementation process of a CURE in an introductory biology laboratory setting. A unique six-week CURE was designed for undergraduates enrolled in a cell biology lab that employs Saccharomyces cerevisiae as a eukaryotic model organism. Students address a research problem that is of interest to the scientific community: Do select chemicals in the environment have adverse effects on the mitotic cell division? Students are first introduced to S. cerevisiae, its life cycle, morphology, growth curve generation and analysis, and the laboratory techniques required to cultivate this organism. Working in groups, students then act as scientists to research primary literature, ask an original question, develop a testable hypothesis, collaborate with peers, design and conduct an experiment, analyze and interpret data, and present their work to their peers. In addition, students are involved in multiple levels of iterative work, including addressing problems or inconsistencies, ruling out alternative explanations, and/or gathering additional data to support assertions.

Research experiences provide a valuable view into the world of science and a great way to explore new fields and careers while developing critical thinking skills. The development and maintenance of databases have allowed researchers to accelerate research in many fields, and understanding how to use them opens doors to actual data for scientific purposes. This resource will give students the opportunity to use research tools with published data to answer questions about immunological topics. The activities in this lesson can be used in Biology, Biotechnology, Microbiology, Bioinformatics, and Introductory Immunology courses. In addition, this activity includes a Student Activity and Instructor Notes with solutions and extra guidance for educators.

Teaching resources, especially active learning pedagogy, are scarce for toxicology compared to what is available for other disciplines. Ecological and human health risk assessment are important aspects of toxicology and are routinely used by government agencies to regulate the registration and usage of many chemicals. Most traditional toxicology classes do not cover how such risk assessments are carried out in real-world scenarios. We developed this case study to introduce concepts and processes of ecological and human health risk assessment in pesticide registration by the U.S. EPA. In Part 1, dialogues among three college friends introduce organic food, pesticides, and the concept of risk. Part 2 and Part 3 build on Part 1 and focus on ecological risk assessment and human health risk assessment, respectively. At the end of each section, students select appropriate exposure and toxicity endpoints to perform a mini-risk assessment and draw conclusions regarding risk. In Part 4, students examine real pesticide monitoring data in various foods and perform basic data organization and analysis. This case is appropriate for upper-level college students taking toxicology or other environmental science related courses. With modifications, the case study may also be suitable for introductory level environmental and biological science students.
