Teaching science and ethics to undergraduates: a multidisciplinary approach

Building connections between biomedical sciences and ethics for medical students

BACKGROUND

Medical ethics education is crucial for preparing medical students to face ethical situations that can arise in patient care. Instances of ethics being integrated into biomedical science education to build the connection between human science and ethics is limited. The specific aim of this study was to measure student attitudes towards an innovative curriculum design that integrates ethics education directly into a biomedical science course in pre-clinical medical curriculum.

METHODS

In this cross-sectional study, three ethics learning modules were designed and built in a biomedical science course in the pre-clinical curriculum. All students of Class of 2024 who were enrolled in the course in 2021 were included in the study. Each module integrated ethics with basic science topics and was delivered with different teaching modalities. The first module used a documentary about a well-known patient with severe combined immunodeficiency disease. The second module was delivered through a clinical scenario on HIV infection. The third module used small group discussion and debate on the topic of blood transfusion. For evaluation, students were asked to self-identify the ethical challenges associated with each module and complete reflective writing to assess their knowledge and attitude. Quantitative and qualitative analyses were conducted on student perceptions of each module.

RESULTS

Likert scale ratings on the usefulness of each module revealed significantly higher ratings for the small group discussion/debate module, seconded by the documentary and lastly the case scenario only modules. Narrative analysis on student feedback revealed three themes: General favorable impression, Perceived learning outcomes, and Critiques and suggestion. Common and unique codes were identified to measure the strengths and weaknesses of each module. Overall, students' perception of the curriculum design was extremely positive.

CONCLUSIONS

This curriculum design enabled us to highlight foundational biomedical sciences and clinical conditions with ethical dilemmas that physicians are likely to face in practice. Students found value in the modules, with a preference for the most active learning method. This study provides insight on a novel approach for integrating medical ethics into biomedical science courses that can be tailored to any institution. Strategies learned include utilizing active learning modalities and discussion.

Teaching Ethics to Undergraduate Psychology Students: Review of the Evidence and Recommendations

Teaching ethics to undergraduate psychology students has been the focus of professional organizations for several years. However, the evidence that psychology programs are teaching ethics and its effectiveness is scarce. In this review, we present recent evidence on teaching ethics based on three themes: delivery of ethics in the curriculum, instructional strategies, and faculty issues related to teaching ethics to undergraduates. We describe a model for incorporating ethics in the culture of the institution. Further, we provide recommendations for both teaching and researching ethics education.

Building New Bioethical Practices through Feminist Pedagogies

The development of a new field such as synthetic biology provides an opportunity to establish new models for bioethics. In this paper, I describe an experimental course aimed at developing bioethical practices through feminist pedagogy. Based in principles of action-orientation and self-reflective learning, the course provided students from diverse fields with the opportunity to work together at the intersections of science, ethics, and community. As greater interdisciplinarity spreads across campuses, I argue that feminist studies departments are well positioned to transform the production of scientific knowledge through bioethics education based in social justice.

Biochemistry in an undergraduate writing-intensive first-year program: Seminar courses in drugs and bioethics

The College of the Holy Cross offers a universal first-year program called Montserrat, in which first-year students participate in a living-learning experience anchored by a yearlong seminar course. The seminar courses are part of a thematic cluster of four to eight courses; students in the cluster live together in a common dormitory and participate in shared co-curricular events designed to engage the entire cluster in intellectual discourse related to the theme. A two-semester seminar within the "Natural World" cluster was offered using biochemical principles as the underlying content. In the first semester, students were introduced to drug design, activity and abuse via student presentations and guided readings on ethnobotany, drug laws, drug use in religion, and prescription drug costs. In the second semester, students discussed primary readings in ethics followed by case study analyses of assisted reproduction technologies, informed consent, genetic privacy, performance enhancing drugs and genetically modified organisms. Student learning outcomes were evaluated via rubrics and a College-facilitated survey.

Using a popular science nonfiction book to introduce biomedical research ethics in a biology majors course

Although bioethics is an important topic in modern society, it is not a required part of the curriculum for many biology degree programs in the United States. Students in our program are exposed to biologically relevant ethical issues informally in many classes, but we do not have a requirement for a separate bioethics course. The Immortal Life of Henrietta Lacks is a recent nonfiction book that describes the life of the woman whose cervical cancer biopsy gave rise to the HeLa cell line, as well as discussing relevant medical, societal, and ethical issues surrounding human tissue use for research. Weekly reading assignments from the book with discussion questions and a final paper were used to engage students in learning about the ethics of human subjects and human tissues research. Students were surveyed for qualitative feedback on the usefulness of including this book as part of the course. This book has been a successful platform for increasing student knowledge and interest in ethics related to biomedical and biological research.

Lessons learned from undergraduate students in designing a science-based course in bioethics

Columbia University offers two innovative undergraduate science-based bioethics courses for student majoring in biosciences and pre-health studies. The goals of these courses are to introduce future scientists and healthcare professionals to the ethical questions they will confront in their professional lives, thus enabling them to strategically address these bioethical dilemmas. These courses incorporate innovative pedagogical methods, case studies, and class discussions to stimulate the students to think creatively about bioethical issues emerging from new biotechnologies. At the end of each course, each student is required to submit a one-page strategy detailing how he or she would resolve a bioethical dilemma. Based on our experience in teaching these courses and on a qualitative analysis of the students' reflections, we offer recommendations for creating an undergraduate science-based course in bioethics. General recommendations include: 1) integrating the science of emerging biotechnologies, their ethical ramifications, and contemporary bioethical theories into interactive class sessions; 2) structuring discussion-based classes to stimulate students to consider the impact of their moral intuitions when grappling with bioethical issues; and 3) using specific actual and futuristic case studies to highlight bioethical issues and to help develop creative problem-solving skills. Such a course sparks students' interests in both science and ethics and helps them analyze bioethical challenges arising from emerging biotechnologies.
