This collection features physics questions with embedded video clips of actual events and systems, such as objects colliding and rockets launching. Created by veteran physics instructor Peter Bohacek, these videos use rulers, grids, frame-counters, and other graphic overlays enabling students to make measurements directly from the video to analyze and apply physics concepts. Students actively participate in the learning experience by collecting the data required to answer questions, giving real-world context to classroom physics.

Key features:

  • Instant and customized feedback: Feedback for each question tells the student if his/her value is too high or too low and suggests ways to improve the quality of the measurement.
  • Question randomization: Each video has multiple versions, enabling WebAssign to randomly select one version when a student begins work on the question. Student feedback is based on the correct values for that video. In addition, key values, such as the mass of an object, are also randomized.
  • Instructional scaffolding: Some questions provide a structure that helps the student learn as he/she progresses through a problem or lab. These scaffolding questions combine traits of labs, tutorials, and word problems.

The result is an exciting, engaging method for augmented physics instruction. This exclusive preliminary collection of questions is available as an additional resource for your WebAssign course at no extra charge. You can adopt it with any textbook supported by WebAssign, or use it with no textbook at all.
