Exploring innovative teaching methods that bridge the gap between biology and engineering
Imagine a world where scientists don't just study biology but engineer it—designing living systems to clean up pollution, build sustainable materials, or even create novel medical treatments.
This isn't science fiction; it's the promise of synthetic biology, a field that applies engineering principles to biological systems. Alongside it, systems biology takes a holistic view, seeking to understand how all the components of living systems work together. These complementary fields are revolutionizing how we approach biological challenges, and they're now transforming how we teach biology to the next generation of scientists 1 .
Breakthroughs like the improved human genome sequence demonstrate the power of collaborative, computational approaches to biological problems 1 .
Protein structure predictions by AlphaFold represent another milestone in computational biology, enabling new approaches to understanding biological systems 1 .
We're living in what many call "the century of biology," with rapid advances in DNA sequencing and synthesis fueling the rise of synthetic biology to solve pressing challenges in medicine, agriculture, and manufacturing 1 .
Focuses on understanding natural biological systems as integrated networks, analyzing how components interact across multiple levels.
Aims to modify, adapt, and re-purpose biological systems toward specific goals, enhancing efficiency and robustness of desired traits 1 .
Researchers plan biological constructs or systems
They create these systems in the laboratory
They measure outcomes against model predictions
They refine understanding and redesign improved systems 1
This framework isn't just for research—it's also a powerful educational model. Educators have discovered that the DBTL cycle aligns remarkably well with Kolb's experiential learning cycle, creating a natural framework for education 1 .
An innovative approach developed at the University of Michigan, Ann Arbor, addresses the challenge of integrating different data types through a modified jigsaw method that mimics how systems biologists work with multiple data types to reconstruct biological pathways 4 .
30-minute background on experimental methods in functional genomics and proteomics 4 .
Class divided into small groups of 5-6 students with random assignment 4 .
Each group receives different sample data sets describing portions of a hypothetical eukaryotic signaling pathway 4 .
After independent data interpretation, representatives present findings, and the class works together to integrate all group findings into a comprehensive pathway representation, revealing the complete picture that wasn't visible from any single data set 4 .
Students grasped that only by integrating all data sets could they reconstruct the complete pathway—experiencing firsthand the power of systems biology 4 .
The active, cooperative approach successfully engaged students with different backgrounds by allowing them to contribute their unique skills 4 .
Student feedback on this cooperative exercise was "extremely positive," indicating effective introduction of complex concepts 4 .

The shift toward research-driven education in systems and synthetic biology represents more than just another curriculum update—it's a fundamental rethinking of how we prepare students for a world where biology has become an engineering discipline.
By introducing students to the DBTL framework and providing hands-on experience with the same tools and approaches used in cutting-edge research, educators are creating a pathway for students to become the next generation of biological innovators 1 .
This educational approach helps break down the traditional boundaries between experimental and theoretical researchers 1 . When life sciences students learn mathematical modeling and computational students gain laboratory experience, they develop a shared language that enables future collaborations.
From the classroom to the research lab, and eventually to applications in sustainability, health, and technology, systems and synthetic biology represent a powerful new way of understanding and engineering living systems. Through innovative educational approaches that mirror real scientific practice, we're not just teaching students about biology—we're empowering them to reshape our biological future 1 9 .
