Learning progressions
are used to describe how students’ understanding of a topic progresses over
time. This study evaluates the effectiveness of different item formats for
placing students into levels along a learning progression for carbon cycling.
The item formats investigated were Constructed Response (CR) items and two
types of two-tier items: (1) Ordered Multiple-Choice (OMC) followed by CR items
and (2) Multiple True or False (MTF) followed by CR items. Our results suggest
that estimates of students’ learning progression level based on OMC and MTF
responses are moderately predictive of their level based on CR responses. With
few exceptions, CR items were effective for differentiating students among
learning progression levels. Based on the results, we discuss how to design and
best use items in each format to more accurately measure students’ level along
learning progressions in science.
