Introduction/Rationale: Immunology, a field known for its complexity and clinical significance, often imposes high cognitive and emotional demands on students. Traditional grading systems can increase stress and impede teamwork, while purely pass/fail systems might reduce accountability and recognition of achievement.
Methods: We at Chicago State University used appropriate surveillance methods, such as direct observation, digital monitoring, biometric sensors, and self-reporting tools. Ensured ethical practices by obtaining informed consent, protecting privacy, and maintaining transparency. Used tools such as LMS analytics, screen-monitoring software, and video analysis platforms to collect data. Analyzed the data using qualitative or quantitative methods.
Results: This study, conducted at Chicago State University's College of Health Sciences and Pharmacy, introduced a hybrid grading model for undergraduate immunology courses that combines traditional letter grades with pass/fail assessments to improve both academic rigor and student well-being. The proposed model assigns letter grades to core knowledge assessments—such as exams, quizzes, and final evaluations—which count for 50% of the overall grade. The other 50% is based on pass/fail assessments, including lab practical, group projects, participation, and reflective writing. This approach fostered skill development, collaboration, and engagement without increasing grade pressure, creating a more inclusive and supportive learning environment.
Conclusion: This flexible approach encourages intrinsic motivation, reduces anxiety, and promotes equity while maintaining academic standards. By aligning assessment methods with the diverse learning objectives of immunology—such as knowledge retention, practical skills, and collaborative inquiry—the hybrid grading system provides a versatile framework suitable for various science curricula. Future research should assess its impact on student performance, engagement, and long-term retention of immunological concepts.
