| Abstract: | The purpose of this project was to develop a valid and reliable science process skill test for middle and high school students. Multiple-choice items were generated for each of five objectives. Following pilot testing and revision, the test was administered to middle and high school students in the northeastern United States. The 36-item test can be completed in a normal class period. Results yielded a mean score of 19.14 and a total test reliability of 0.86. Mean difficulty and discrimination indices were 0.53 and 0.35, respectively. Split-test correlations coefficients between TIPS II and the original TIPS items were 0.86 and 0.90. TIPS II provides another reliable instrument for measuring process skill achievement. Additionally, it increases the available item pool for measuring these skills. |
