In an Invited Comment in Nature Physics that published on May 31, physicist Natasha Holmes and her co-author describe how undergraduate labs that encourage investigation and decision-making are more positive for students – and are more effective -- than those that focus on verification of concepts in textbooks.
“Rather than using the experiments in a lab to demonstrate a particular theoretical model, labs should showcase what it means to do experimental physics: the approach, techniques, skills and ways of thinking when conducting authentic physics experiments. This focus is important not only for future scientists but also for citizens, to better equip them to interact with the complexity of the world and interpret scientific advancement in light of uncertainty,” write Holmes, Ann S. Bowers Assistant Professor in the Department of Physics, and Emily Smith, a former physics postdoctoral researcher at Cornell.
Holmes’ lab studies teaching and learning in physics and other science, technology, engineering, and math (STEM) courses. She is a founder of the Cornell Discipline-based Education Research group that brings together researchers from across the campus for collaborative scholarship in this emerging field that draws on psychology, education and cognitive science research with the goal of enhancing student learning and instructor teaching.

Artist concept of the gas giant planet WD 1856 b orbiting a white dwarf star. The planet is 7 times larger than the Earth-sized white dwarf it orbits. WD 1856 b has methane and hazes in its atmosphere, which would give it a similar color to Saturn's moon Titan. The white dwarf formed from a star that died 5 billion years ago, and has been cooling ever since, giving it an orange colour similar to the Sun.
