This paper focuses on how best to evaluate student achievement in science. Many issues such as issues of test construction, validity, and reliability, and how to measure hands-on achievement must be considered. Qualitative evaluations are harder to explain, but can yield valuable information. The use of portfolios is an example of a technique that…

There is presently much disagreement about how students should be evaluated effectively to determine their progress. Some common methods are reviewed, including standardized tests and performance-based evaluation such as portfolios. Continuous experimentation is necessary in the effort to develop better measurement approaches. (SLD)
