  • Medical students at a fair. Credit: Danieladelrio

    Casting a Wide Net via Case Studies: Educating across the undergraduate to medical school continuum in the biological...

    Learning Objectives
    At the end of this lesson, the student should be able to:
    • Consider the potential advantages and disadvantages of widespread use of whole genome sequencing and direct-to-consumer genetic testing.
    • Explore the critical need to maintain privacy of individual genetic test results to protect patient interests.
    • Dissect the nuances of reporting whole genome sequencing results.
    • Recognize the economic ramifications of precision medicine strategies.
    • Formulate a deeper understanding of the ethical dimensions of emerging genetic testing technologies.
  • An active-learning lesson that targets student understanding of population growth in ecology

    Learning Objectives
    Students will be able to:
    • Calculate and compare population density and abundance.
    • Identify whether a growth curve describes exponential, linear, and/or logistic growth.
    • Describe and calculate a population's growth rate using linear, exponential, and logistic models.
    • Explain the influence of carrying capacity and population density on growth rate.
  • This is a representation of what might happen during peer discussion.

    In-class peer grading of daily quizzes increases feedback opportunities

    Learning Objectives
    Each of these objectives are illustrated with a succinct slide presentation or other supplemental material available ahead of class time through the course administration system. Learners found it particularly helpful to have video clips that remind them of mathematical manipulations available (in the above example objective c). Students understand that foundational objectives tend to be the focus of the quiz (objectives a-d) and that others will be given more time to work on together in class (objectives e-g), but I don't specify this exactly to reduce temptation that 'gamers' take a shortcut that would impact their group work negatively later on. However, the assignment for a focused graded group activity is posted as well, so it is clear what we are working towards; if desired individuals could prepare ahead of the class.
  • Students participating in the peer review process. Practicing the writing of scientific manuscripts prepares students to understand and engage in the primary literature they encounter.
  • Students at Century College use gel electrophoresis to analyze PCR samples in order to detect a group of ampicillin-resistance genes.

    Antibiotic Resistance Genes Detection in Environmental Samples

    Learning Objectives
    After completing this laboratory series, students will be able to:
    • apply the scientific method in formulating a hypothesis, designing a controlled experiment using appropriate molecular biology techniques, and analyzing experimental results;
    • conduct a molecular biology experiment and explain the principles behind methodologies, such as accurate use of micropipettes, PCR (polymerase chain reaction), and gel electrophoresis;
    • determine the presence of antibiotic-resistance genes in environmental samples by analyzing PCR products using gel electrophoresis;
    • explain mechanisms of microbial antibiotic resistance;
    • contribute data to the Antibiotic Resistance Genes Network;
    • define and apply key concepts of antibiotic resistance and gene identification via PCR fragment size.

    A Hands-on Introduction to Hidden Markov Models

    Learning Objectives
    • Students will be able to process unannotated genomic data using ab initio gene finders as well as other inputs.
    • Students will be able to defend the proposed gene annotation.
    • Students will reflect on the other uses for HMMs.
  • A photo of grizzly bears fishing in the McNeil Falls in Alaska, taken using BearCam by Lawrence Griffing.

    Authentic Ecological Inquiries Using BearCam Archives

    Learning Objectives
    Students will be able to:
    • conduct an authentic ecological inquiry including
      • generate a testable hypothesis based on observations,
      • design investigation with appropriate sampling selection and variables,
      • collect and analyze data following the design, and
      • interpret results and draw conclusions based on the evidence.
    • write a research report with appropriate structure and style.
    • evaluate the quality of inquiry reports using a rubric.
    • conduct peer review to evaluate and provide feedback to others' work.
    • revise the inquiry report based on peer feedback and self-assessment.

    Taking the Hassle out of Hasselbalch

    Learning Objectives
    Students will be able to:
    1. Characterize an aqueous environment as acidic or basic.
    2. Explain that pKa is a measure of how easy it is to remove a proton from a molecule.
    3. Predict ionization state of a molecule at a particular pH based on its pKa (qualitative use of the Henderson-Hasselbalch equation).
    4. Calculate the ratio of protonated/unprotonated forms of ionizable groups depending on chemical characteristics and /or environment pH (quantitative use of the Henderson-Hasselbalch equation).
    5. Apply this knowledge in a medical context.

    Sex-specific differences in Meiosis: Real-world applications

    Learning Objectives
    After completion of the lesson students will be able to:
    1. Describe the differences between female and male meiosis.
    2. Interpret graphical data to make decisions relevant to medical practices.
    3. Develop a hypothesis that explains the difference in incidence of aneuploidy in gametes between males and females.

    Why do Some People Inherit a Predisposition to Cancer? A small group activity on cancer genetics

    Learning Objectives
    At the end of this activity, we expect students will be able to:
    1. Use family pedigrees and additional genetic information to determine inheritance patterns for hereditary forms of cancer
    2. Explain why a person with or without cancer can pass on a mutant allele to the next generation and how that impacts probability calculations
    3. Distinguish between proto-oncogenes and tumor suppressor genes
