Expert Notes AvailableView expert commentary on strengths and cautions for this instrument
Strengths

Uses pre- and post-lesson measures with aligned content questions, allowing for direct comparison of students’ conceptual understanding before and after the instructional intervention.

Cautions

Uses relatively simple scoring (e.g., binary correct/incorrect for content questions), which may not capture partial understanding or nuances in students’ reasoning.

This science assessment consists of pre- and post-lesson survey instruments designed to measure students’ understanding of science concepts following participation in LEGO Mindstorms-based activities. The assessments include both content and evaluation questions and are administered immediately before and after instruction.

The content portion includes multiple-choice, short-answer, and open-ended questions aligned to specific science topics such as simple machines, force and motion, and fluid flow. These questions are repeated across pre- and post-assessments to examine changes in students’ knowledge. Student responses are scored using a binary rubric, with answers categorized as correct or incorrect based on predefined criteria for each concept.

The instrument is designed to compare pre- and post-instruction performance to examine changes in students’ conceptual understanding of science topics addressed during the activities.
