The FOSSTM pretest assessment for sound physics was administered to the fourth
grade treatment and control groups prior to the science instruction in the
investigative modules. The same posttest was repeated at the conclusion of the
eight investigations. The TDSAS survey measuring student attitudes toward science
was given to the students at the beginning and then again at the end of the
investigations. This pre/post design procedure was the same for the fifth grade
treatment and control groups in the study of solar energy.
