The Science-in-the Moment (SciMo) Project is designed to help researchers and teachers understand how high school students feel when engaged in science learning contexts. Students in 12 different science classrooms provided multiple reports of their momentary experience in science. Classrooms were also videotaped. The information gathered will be used to inform science teachers on how their students react to specific courses, content units, and instructional practices. The project also examines gender differences in students' science experiences.
