This paper reports the use of Tracker as a computer-based learning tool to support effective learning and teaching of "toss up" and free fall motion for beginning secondary three (15?year-old) students. The case study involved (N = 123) students from express pure physics classes at a mainstream school in Singapore. We used eight…

Inexpensive video analysis technology now enables students to make precise measurements of an object's position at incremental times during its motion. Such capability now allows users to "examine", rather than simply "assume", energy conservation in a variety of situations commonly discussed in introductory physics courses. This article describes…
