The ability to draw visual representations such as diagrams and graphs is considered fundamental to science learning. Science exams therefore often include questions which require students to draw a visual representation, or to augment a partially provided one. The design features of such questions (e.g., layout of diagrams, amount of answer…

Linking assessment and curriculum in science education, particularly within the topic of matter and its changes, is often taken for granted. Some of the fundamental elements of the assessment, such as the choice of wording and visual representations, as well as its relation to the curricular sequence, remain understudied. In addition, very few…

Capturing the nature of students' mental representations and how they change with learning is a primary goal in science education research. This can be challenging in spatially intense domains, such as geoscience, architecture, and engineering. In this research, we test whether sketching can be used to gauge level of expertise in geoscience,…

This study examined some of the methodological approaches used by students to construct causal maps in order to determine which approaches help students understand the underlying causes and causal mechanisms in a complex system. This study tested the relationship between causal understanding (ratio of root causes correctly/incorrectly identified,…

Science education has moved from the traditional lecture-and-demonstration model toward a student inquiry model. Inquiry activities allow students to discover many relationships of science for themselves. However beneficial this shift may be, former assessment methods used in the traditional model may no longer effectively determine student…
