Student knowledge in a subject area prior to and after instruction has traditionally been assessed by administering a pre- and post-test, usually multiple choice, though recent studies criticize the use of even the best-constructed multiple choice tests. This study assessed college freshmen's knowledge before and after a laboratory experience in…

Describes the construction of a chemistry laboratory. Also discusses the place of science in school technology teaching, a study of students' understanding of simple quantitative relationships in chemistry, and the objectives of school physics. (JN)

Describes a study designed to determine if the amount of time allocated for answering multiple true/false type questions affects the grades of the medical students taking the tests. Students who had 2-1/4 minutes to answer each question scored significantly better than those who had 1-1/2 minutes or 3 minutes. (TW)

Based on the premise that multiple choice tests can be used as diagnostic tools for teachers in identifying and remedying student misconceptions, this study focused on the development of an instrument for diagnosing secondary students' understanding of photosynthesis and respiration.

Discusses some difficulties that medical students experience in taking exams containing multiple choice questions. Differentiates between multiple true/false type questions, in which several answers may be true, and one-out-of-four type, in which only one answer is correct. Provides tips for taking and making multiple choice tests. (TW)

The purpose of this manual is to encourage discussions among science teachers about desired student outcomes in science and assessments appropriate to these outcomes. Once teachers know clearly what they hope to accomplish with their students, choosing appropriate assessment measures follows. Assessment methods described center on observing…
