Sample Multiple Choice Test Questions

Merchant et al. (2012) investigated the impact of a 3D desktop virtual reality environment on the learning of the valence shell electron pair repulsion (VSEPR) theory in an introductory chemistry class. Their sample consisted of 204 undergraduates enrolled in a chemistry course at a university in the USA. They used 11 -multiple-choice questions to assess the students understanding of molecular angles, molecular geometry, and species identifications. They also constructed 15 items to measure the students self-efficacy for learning VSEPR theory. The students self-efficacy was found to positively relate to their scores on the multiple-choice test. 

Near the end of this study guide you will find additional sections that may help you to study for the final examination in the course. The SUMMARY OF SYNTHETIC METHODS lists the important ways to synthesize each class of compounds discussed in the text. It is followed by the SUMMARY OF REACTION MECHANISMS. Both of these sections have references to appropriate portions of the text, in case you feel that further review is necessary. Finally, you will find two lists of sample test questions. The first deals with synthesis, and the second is a list of multiple-choice questions. Both of these sets should help you prepare for examinations. 

Now let s examine an actual standardized test problem, four multiple-choice questions, and their answers. Encourage your student to practice on any sample problem in this book. 

A major new feature of this edition is the addition of a second Practice Exercise to accompany each Sample Exercise within the chapters. The new Practice Exercises are multiple-choice with correct answers provided for the students in an appendix. Specific wrong answer feedback, written by the authors, will be available in MasteringChemistry The primary goal of the new Practice Exercise feature is to provide students with an additional problem to test mastery of the concepts in the text and to address the most common conceptual misunderstandings. To ensure the questions touched on the most common student misconceptions, the authors consulted the ACS Chemistry Concept inventory before writing their questions.
