DLESE description of Development of an Assessment of Student Conception of the Nature of Science

This article describes a study in which a series of general education and introductory science courses were assessed using a Likert-scale instrument. As universities across the country have begun to make changes in their science curricula, especially with regards to non-science majors, assessment of courses and curricula has lagged behind implementation. The Likert-scale instrument, Attitudes and Conceptions in Science (ACS), provides a means by which faculty can determine the partial effectiveness of introductory and general education science courses. The established validity and reliability of this test suggests that its use in a variety of courses could allow identification of specific teaching methods, content, or other course characteristics that promote scientific literacy.
