National Fire Academy Test Technical Manual for the Chemistry of Hazardous Materials Course. Final Exam.
Clark, Burton A.
This first test and technical manual explains the development, purpose, use, validity, and reliability of the criterion-referenced final examination for the Chemistry of Hazardous Materials course of the National Fire Academy in Emmitsburg (Maryland). Because of possible diversity in the testing knowledge and background of readers, the manual includes an overview of testing, explaining technical issues associated with validity, reliability, and optimal cut score. The examination consists of 100 questions measuring 48 objectives of the course. Six test reviewers determined content validity, and the development team and the six reviewers considered the domain validity of the instrument. Decision validity was determined by pretesting and posttesting 127 students in 5 classes. Test reliability was measured for 221 students using the threshold loss function reliability index, the internal consistency reliability, and the standard error of measurement (based on 44 posttest scores). Item analysis procedures used were: (1) sensitivity to instructional effects (127 examination scores); (2) Hambleton's item review to check bias (2 reviewers); and (3) informed feedback from 70 students. Faculty and students can be confident of the examination's validity and reliability. One graph and three tables present study data. A list of 22 references, 4 appendices describing the course, and instructions to students and reviewers are included. (SLD)
