Students in 4 Canadian high school physics classes completed instructional sequences in two key physics topics related to motion--Straight Line Motion and Newton's First Law. Different sequences of laboratory investigation, teacher explanation (lecture) and the use of computer-based scientific visualizations (animations and simulations) were…

Although previous research has indicated no significant relationship between sequencing of programed instructional materials and terminal achievement, it is felt that certain conditions might produce such a relationship. In order to test this idea, a hierarchy of word meanings was constructed, in which each definition was dependent on the previous…

The purpose of this study was to develop and test a factor analysis procedure for sequencing self-instructional materials associated with concept attainment. The effects of a computer-generated psychological sequence compared with a random sequence of concepts on sequential decision-making by three achievement levels of students were determined.…
