Strengths
Elicits students’ understanding through model-based tasks, requiring them to create and explain visual representations of scientific processes, which helps reveal how students organize ideas about structure, function, and inheritance
Cautions
Students’ performance on the assessment depends heavily on their ability to construct and interpret models, so difficulties with drawing, labeling, or representing ideas may obscure their actual conceptual understanding of inheritance.
This assessment consists of student-generated modeling tasks designed to measure elementary students’ understanding of inheritance through visual and explanatory representations. Students are asked to create, use, and revise models that show how traits are passed from parent organisms to offspring within a given context.
The instrument requires students to draw and label key components involved in inheritance, such as parent organisms, offspring, and internal factors related to traits, as well as depict processes like reproduction. Students are also expected to explain how these components and processes are connected, including how traits are transferred across generations.
Student responses are evaluated using a rubric based on five dimensions: components, sequences, explanatory process, mapping, and scientific principle. These dimensions capture how students identify relevant elements, represent relationships, and connect their models to underlying scientific ideas.
The instrument is designed to examine how students organize and communicate their understanding of inheritance through model-based explanations in elementary science settings.
