Breast Cancer Teacher Guide
Peter J. T. White is an associate professor of Science Education and Entomology at Michigan State University. He is responsible for all the curricular content referred to within the teacher guide and has personally taught introductory cell and molecular biology using the story of breast cancer several times.
Eva S. Conley is a recent graduate at Michigan State University. She was an undergraduate learning assistant for two iterations of the course that was taught using the breast cancer example. She played an important role in putting the breast cancer curricular materials together into an early draft of the teacher guide that was later edited and revised into its final format.
Audra Balcer and J.P. Lawrence were early adopters and helped to refine and reshape some of the materials to help them be more universally-adoptable in different class contexts and formats.
Thanks also to Jim Smith, Merle Heidemann, Joseph Reidy, and David Filice for their collaborative work on the Evo-Med-Ed project, focused on designing and testing curricular materials for higher ed through the lens of human health and disease.
One iteration of the implementation of the materials in this teacher guide, along with student outcomes, is described:
Filice, D. C., Riedy, J. J., Heidemann, M. K., Smith, J. J., & White, P. J. (2023). Evaluating introductory biology student perceptions surrounding the use of integrative cases related to human health for evolution education. Evolution: Education and Outreach, 16(1), 6.
Introductory cell and molecular biology can feel like a disjointed tour of isolated processes: mitosis on Monday, DNA replication on Wednesday, central dogma on Friday. Many students find learning more meaningful when those processes are woven into a single interconnected narrative. The study of cancer provides such an opportunity. Cancer is the ultimate story of cellular evolution; rogue cells that gain a selective advantage, through mutation, that allow them to outcompete their neighbors and proliferate. While cancer can be a difficult subject matter, particularly for those whose lives have been touched by it, many students – regardless of their personal experience with the disease – are eager to learn about it. In fact, the personal relevance of cancer seems to motivate students and answers the question of “WHY” they should learn biology (Filice et al., 2023).
Why breast cancer? While cancer is a universally recognized health issue, roughly one in eight women will be diagnosed with breast cancer at some point in their lifetime, and it ranks among the top cancers affecting all genders worldwide.
How does cancer connect with key disciplinary concepts? To understand cancer, students need to master the structure and function of DNA, the nature of mutations, transcription and translation regulation, protein structure and function, cell cycles, natural selection and more! Once students start to think of cancer cells as “individuals”, it makes it easier to think about ecological processes in a microbiological world, supporting a more holistic understanding of biology across scales, from nucleotides to populations.
Breast cancer occurrence and treatment isn’t best understood by memorizing pathways; it requires systems thinking. Students can evaluate data, hypothesize how a single nucleotide change cascades to macroscopic disease, and debate ethical dilemmas around genetic testing. These are the types of core competencies and science and engineering practices that we find in Vision & Change for higher ed (AAAS, 2010) and in the NGSS for upper secondary or AP courses (NGSS Lead States, 2013).
Ultimately, the study of cancer transforms introductory cell and molecular biology from a fragmented checklist of processes into a cohesive, life-relevant exploration of how molecules, cells, and evolutionary forces intertwine to shape human health. It captivates students’ curiosity, grounds abstract mechanisms in personal experience, and nurtures the analytical mindset students will need as scientists, healthcare professionals, or scientifically literate citizens.
How This Guide is Organized
Pedagogical Note
The class sessions within this teacher guide were designed to be implemented with a flipped teaching pedagogy. Students prepare for class by watching a short tailored lecture video, at home, on the upcoming subject material. Each video was written and recorded specifically with this teacher guide in mind.
These videos are freely and publicly available on YouTube at: https://www.youtube.com/@evo-ed
One of the risks of this flipped teaching pedagogy is that a subset of students may undertake only a cursory viewing of the pre-class video and thus be unprepared to engage in deeper learning opportunities that the pedagogy is designed for. To avoid this, students can be assigned homework to complete along with the video viewing. There are many ways this can be achieved. For example, you might require that students compose summary notes of the lecture videos (but consider Muller & Oppenheimer, 2014), or start class with a “minute paper” (Chizmar & Ostrovsky, 1998) or “muddiest point” exercise (Carberry et al, 2013). Whatever method is used, students should be encouraged – and, when appropriate, held accountable for – individual synthesis and sensemaking, prior to coming to class.
TABLE OF CONTENTS
Why Use Breast Cancer to Teach Introductory Cell & Molecular Biology
1. Breast Cancer Introduction & Cancer Growth
3. BRCA & HER2
4. Cell Biology and the Cell Cycle
5. Trade Offs, Evolution, and Breast Cancer
In this teacher guide, each lesson within the EvoEd Breast Cancer Unit follows a four-step process: (1) a pre-class video, (2) an in-class quiz, (3) a mini-lecture, and (4) a worksheet.
STEP 1: PRE-CLASS VIDEO
[Students complete asynchronously]
Before coming to class, students watch one or two short videos that introduce them to the core ideas and key content of the upcoming lesson. This gives them an opportunity to familiarize themselves with the fundamental terminology, core concepts, and key processes at their own pace, setting the stage for deeper in-class learning.
STEP 2: IN-CLASS QUIZ
[5-10 minutes]
Each class session begins with a short in-class quiz to hold students accountable for their classroom preparation, each day. Sample quizzes are provided, but teachers are encouraged to create their own questions if desired, and use whatever style of quiz best suits their teaching style.
STEP 3: MINI “RECAP” LECTURE
[<10 minutes]
Following the quiz, instructors can deliver a very short interactive-engagement-style “recap lecture”. This serves two purposes. First, it allows students who were unprepared or underprepared to gain some familiarity with the subject material prior to the problem-solving stage. Second, it allows the instructor to introduce new and emergent ideas to the discussion, or to connect the content of the day with student prior-learning. While this guide provides some options for generic review slides, instructors can customize the “recap-lecture” portion to best meet the needs of their course.
Since passive listening is not as effective for learning, keep this recap lecture short, concise and interactive. Student engagement can be boosted using interactive elements such as:
STEP 4: WORKSHEET & PROBLEM SOLVING
[~45-60 minutes]
For the remainder of the class session, students work on a lesson-specific worksheet. In some formats, students may benefit from first having an opportunity to work on the worksheet individually before working with a partner or in small groups. During this stage, instructors can circulate around the room and actively engage with students to probe their thinking, foster discussion, and answer questions that arise. At the end of class, instructors can choose to assess their worksheets for completeness and/or correctness, and can allow students to keep the worksheets to use as study aids if appropriate.
What about Answer Keys?
This Teacher Guide does not include answer keys for the worksheets. Instead, students can be encouraged to use the class time to work with their peers, or engage with the instructor(s) about any questions they are unsure about. In today’s day and age, students have a myriad of online tools and resources they can use to check factual information. Furthermore, depending on the class session, the course instructor may take some time near the end of the allotted time to go over one or more of the worksheet questions if they observe that students are struggling with a particular concept.
End-of-Class Checkout.
Instructors may want to set up a system where students are required to demonstrate their worksheet progress at the end of class. This guards against students simply taking the assignment “to-go”. One of the biggest values with the flipped-approach to teaching and learning is that students are afforded time in-class to work together, and to consult with the instructor(s) about challenging course material. If/when students take their copy of the worksheet and then leave class to “work on it at home (alone)” –or worse, get the answers from a friend– they miss out on valuable learning time.
SESSION 1 | BREAST CANCER INTRODUCTION |
Description | This class session establishes a foundation for understanding cancer. Students work from a simple definition of cancer to an exploration of how cancer progresses from a small collection of cells, to a hyperplasia growth to a malignant tumor. Since this curricular unit focuses on cancer of the breast, students also learn the basic anatomy of the breast. Most breast cancers are due to mutations in fast growing duct cells (due to hormone levels), resulting in a type of cancer called invasive ductal carcinoma. |
