Assessing students’ understanding of the greenhouse effect by looking at language use over time

This study suggests that the assessment of students’ understanding of scientific vocabulary, concepts, and reasoning associated with the greenhouse effect may be better accomplished by observing and understanding learners’ developing language use over time. The indication of previous research that students hold tenacious misconceptions may be an artifact of the questionnaires used. The authors argue that listening to student conversations is the key to better recognize learning. This paper can help ISE educators think more deeply about how and when to assess for student understanding, including considering most appropriate and informative methods.
