Relationship among laboratory instruction, attitude toward science, and achievement in science knowledge

Abstract

This study investigated the use of a hands-on laboratory program as a means of improving student attitude toward science and increasing student achievement levels in science knowledge. Using a posttest-only control group design, curriculum referenced objective examinations were used to measure student achievement in science knowledge, and a posttest Q-sort survey was used to measure student attitude toward science. A one-way analysis of variance compared the groups' differences in achievement and attitude toward science. Analysis of covariance was used to determine the effect of the laboratory treatment on the dependent achievement variable with attitude toward science as the covariable. The findings showed that students who had regular laboratory instruction (a) scored significantly higher (p < .01) on the objective examination of achievement in science knowledge than those who had no laboratory experiences; (b) exhibited a moderate, positive correlation (r = .406) between their attitude toward science and their achievement; and (c) scored significantly higher (p < .01) on achievement in science knowledge after these scores were adjusted on the attitude toward science covariable. There were no significant differences in achievement or attitude toward science for the limited English proficiency groups. It was concluded that laboratory instruction influenced, in a positive direction, the students' attitude toward science, and influenced their achievement in science knowledge. It was recommended that science instruction include a regular laboratory experience as a demonstrated viable and effective instructional method for science teachers. This model of science instruction has been shown to be effective with students of diverse backgrounds who live within large urban centers. J Res Sci Teach 34: 343–357, 1997.
