New Studies in Education: Measurable Outcomes of Individual Laboratory Work in High School Chemistry
by Ralph E. Horton - 1929
THIS study of laboratory practice in chemistry presents a new point of view and a new method of attack on a well-worn but vexing problem in science. 1 Previous studies, such as those of Coop-rider, Kiebler and Woody, Wiley, and Carpenter, sought to measure success in terms of written tests. This study questions the validity of this means and offers a novel but well-validated group of manual performance tests for measuring the abilities under consideration. The experimental program, which covered a period of two years, was carefully planned and controlled. Besides presenting some rather astonishing facts and some new techniques of measurement in science, the study offers possibilities of usefulness as a guide to experimentation in other fields of instruction.
