A three-part project for students in physical chemistry, computational chemistry, or independent study is described in which they explore applications of valence bond (VB) and molecular orbital-configuration interaction (MO-CI) treatments of H[subscript 2]. Using a scientific spreadsheet, students construct potential-energy (PE) curves for several…

Describes the development and evaluation of a placement test used as a major determinant of eligibility to enroll in first-semester general chemistry at California State University, Fullerton. Contains 17 references. (WRM)

Describes an exam question which challenges college freshmen, enrolled in chemistry, to derive temperature dependence of an equilibrium constant. The question requires cognitive response at the level of synthesis. (Author/SA)

Presented are the combined test results of chemistry students from seven Central Indiana schools on the ACS-NSTA achievement exam, Form 1975, Part 1. Additional variables investigated include sex, grade level, Longeot classification, and an item analysis of the test items. (BT)

Describes three examination questions which could be used in college chemistry courses. Discusses each problem and gives acceptable solutions. Problems include: "A Multi-Topic Problem for General Chemistry"; "Consumption of Air by Biuret Reagent--a Question Involving Experimental Design"; and "An Instructive Problem in Heterogeneous Equilibrium."…

Presents five problems on organic stereochemistry in the form of an open-book quiz meant for senior undergraduates and graduate students in chemistry. Provides some acceptable solutions to the problems. (TW)

Presents three examination questions, graded in difficulty, that explore the topic of potential energy surfaces using a diagrammatic approach. Provides and discusses acceptable solutions including diagrams. (CW)

Discusses the need to develop laboratory practical examinations in chemistry which attempt to measure students higher order thinking skills and conceptual understanding rather than simply their laboratory skills. Examples of examination questions being used in general chemistry laboratory courses at the State University of New York at Cortland are…

Contains two articles relating to chemistry examination questions. One provides examples of how to sequence multiple choice questions so that partial credit may be given for some responses. The second includes a question and solution dealing with stereoisomerism as a result of free radical chlorination of a nonstereoisometic substance. (TW)
