This book investigates the challenge of accurately measuring student proficiency in scientific inquiry through hands-on performance assessment. Karen Ostlund, an experienced educator, provides a structured framework for teachers to evaluate how students apply scientific process skills in real-world classroom scenarios. The text argues that science literacy is best demonstrated through active participation rather than traditional testing, offering a systematic approach to tracking student growth over time.

Educators frequently utilize this text as a practical resource for developing classroom-based assessment tools. Experts highlight the book's utility in bridging the gap between theoretical science knowledge and observable student performance.
