The first of three sequels to the booklet "Student Assessment," this booklet begins by describing and providing examples of four different forms that objective questions can take: (1) conventional multiple choice questions; (2) true/false questions; (3) assertion/reason items; and (4) matching items. Guidance is offered on how to decide which type of question to use in a given situation, and on how to write objective questions of different types. Methods for evaluating objective questions are then discussed, including evaluation by a colleague or validation panel and quantitative evaluation. Advice on how to mark objective questions concludes the booklet. Three general references and three subject-based references for teachers of chemistry, physics, and mathematics are recommended for further reading. (MES)
