Abstract
Chemistry faculty members are highly skilled in obtaining, analyzing, and interpreting physical measurements, but often they are less skilled in measuring student learning. This work provides guidance for chemistry faculty from the research literature on multiple-choice item development in chemistry. Areas covered include content, stem, and response construction; item analysis; item difficulty; and item discrimination. The goal is to help faculty construct high-quality, reliable, and valid multiple-choice items to evaluate students’ ability to meet learning objectives and to demonstrate proficiency in the content domain under study. Using item-writing guidelines based upon the research literature allows faculty to create assessments that are reliable and valid, with greater ability to discriminate between high- and low-achieving students.

Conclusion
The research-based resources described herein can help faculty develop multiple-choice items for exams and quizzes that measure student achievement of learning objectives and proficiency in a content domain. In the laboratory chemists collect measurements and seek to obtain the best measures possible for the phenomena under study. In the classroom faculty should have the same goal. Using item-writing guidelines based upon research allows faculty to create assessments that are more reliable and valid, with greater ability to discriminate between high- andlow-achieving students than rulesderived fromprivate empiricism.23 Faculty can use student performance, item difficulty, discrimination, and response distribution to interpret the students’ ability to meet course learning objectives. Assessment outcomes can suggest meaningful changes in a course relevant to the learning objectives and the curriculum that benefit students and faculty.
