The Effect of Data Acquisition-Probeware and Digital Video Analysis on Accurate Graphical Representation of Kinetics in a High School Physics Class

Abstract

The effects of two types of two well-established microcomputer-based teaching methods were examined for their effect teaching high school students kinetics. The use of data acquisition probeware and digital video analysis were studied for their impact on students’conceptions and ability to interpret graphical relationships to real world events. The abilities of high school physics students to accurately graph kinetics using distance, velocity and acceleration in one dimensional motion varied between and among the groups. Using a split category random assignment analysis students investigated these motions with both. In a quasi experimental fashion students received similar instruction on each but in a different sequence. Students received the similar teaching in reverse order and both strategies were found to be successful and complementary. There were indications student achievement was higher for velocity–time and acceleration-time graphs using the digital video analysis method. Implications for this study on teaching tools, methodologies, curriculum development, program implementation, and assessment are discussed.
