Evaluation of Procedure-Based Scoring for Hands-On Science Assessment

摘要: This article evaluates a procedure-based scoring system for performance assessment (an observed paper towels investigation) and notebook surrogate completed by fifth-grade students varying in hands-on science experience. Results suggested interrater reliability of scores notebooks was adequate (>.80) with the former higher. In contrast, agreement on procedures higher (.92) than (.66). Moreover, notebooks, varied student experience, but this not so performance. Both observed-performance measures correlated less traditional ability did multiple-choice achievement test. The correlation between two assessments test only moderate (mean = .46), suggesting that different aspects have been measured. Finally, .83, may provide reasonable, albeit reliable, students.
