Liu, Ou Lydia; Lee, Hee-Sun; Linn, Marcia C. – Educational Assessment, 2011
Both multiple-choice and constructed-response items have known advantages and disadvantages in measuring scientific inquiry. In this article we explore the function of explanation multiple-choice (EMC) items and examine how EMC items differ from traditional multiple-choice and constructed-response items in measuring scientific reasoning. A group…

Liu, Ou Lydia; Lee, Hee-Sun; Linn, Marcia C. – Journal of Research in Science Teaching, 2011
Science education needs valid, authentic, and efficient assessments. Many typical science assessments primarily measure recall of isolated information. This paper reports on the validation of assessments that measure knowledge integration ability among middle school and high school students. The assessments were administered to 18,729 students in…

Lee, Hee-Sun; Liu, Ou Lydia; Linn, Marcia C. – Applied Measurement in Education, 2011
This study explores measurement of a construct called knowledge integration in science using multiple-choice and explanation items. We use construct and instructional validity evidence to examine the role multiple-choice and explanation items plays in measuring students' knowledge integration ability. For construct validity, we analyze item…

Lee, Hee-Sun; Linn, Marcia C.; Varma, Keisha; Liu, Ou Lydia – Journal of Research in Science Teaching, 2010
We investigated how student understanding of complex science topics was impacted when 27 teachers switched from typical to inquiry instruction in a delayed cohort comparison design study. For the same set of science topics, the teachers used typical methods of instruction in the first year and online, visualization rich inquiry units in the second…
