THE PROCESS OF BIOLOGICAL INVESTIGATIONS TEST.

The article presents a study that examines the new instrument "Processes of Biological Investigations (PBIT)" to measure the outcome of various treatments and to improve the learning of science process skills. The goal of this study is to develop and validate an easily administered, reliable, paper-and-pencil test for high school biology students that would measure the science process skills of interest. In this study, the PBIT was developed using examples taken from biology to measure skill achievement. The results show that the PBIT appears to be a valid and reliable instrument to be used in the biology classroom by teachers and researchers interested in determining the effectiveness of inquiry instruction.
