An analysis of frequency of hands-on experience and science achievement

A variance analysis of the relation between the amount of time students spent experiencing hands-on science and science achievement was performed. Data collected by the National Education Longitudinal Study of 1988 on a nationally representative sample of eighth-grade students were analyzed. Student achievement in science was measured by a cognitive test battery developed by the Educational Testing Service. Information regarding the frequency of hands-on experience was collected through a self-administered teacher questionnaire, which included a series of questions specific to the science curriculum. From the analysis it was concluded that significant differences existed across the hands-on frequency variable with respect to science achievement. Specifically, students who engaged in hands-on activities every day or once a week scored significantly higher on a standardized test of science achievement than students who engaged in hands-on activities once a month, less than once a month, or never. © 1996 John Wiley & Sons, Inc.
