Abstract | This document advances the premise that the scientific method to identify cause-effect relationships is undoubtedly the single most important factor in the geometric expansion of scientific advances evidenced thus far during the 20th century. To understand these advances and to make educated decisions concerning them, the citizenry must be scientifically literate. It is further argued that to be scientifically literate, individuals must understand the scientific process. The materials provide an example of an investigation which employs the scientific method to learn about some aspects of sound. Once data are collected, as a result of student investigation, they are computerized as a method of identifying trends. In the investigation students use active inquiry, group processes and Piagetian principles to determine how various factors interact to produce the pitch one hears. The investigation is an extension of the one where all jar or glass sizes are identical and, therefore, the glass size variable automatically controlled. A set of instructions for developing AppleWorks data base computer files (comprising four-fifths of the document) is attached. (PK) |
