Assesses Scientific Attitude Inventory (SAI) by examining the instrument and 30 studies in which it has been used. In addition, shows how conceptual analysis may be used to investigate validity of a research instrument. Indicates that SAI needs reworking since it is less than certain of what is being measured.

Reliability, validity, and standards-setting procedure for a criterion-referenced test (Test of Metric Skills) were examined for use in science curricula. Results indicate a number of factors influencing test reliability/validity and that science teachers need to be aware of these factors to enhance accuracy of their judgments. (Author/JN)

Describes development and validation of a 24-item test which assesses student performance on a set of 12 objectives related to planning and constructing an investigation. In addition to sound psychometric properties, the test is distinctive because it includes a set of interrelated cumulative objectives which reflect autonomous problem solving.…
