The Ocean Literacy movement began in the U.S. in the early 2000s, and has recently become an international effort. The focus on marine environmental issues and marine education is increasing, and yet it has been difficult to show progress of the ocean literacy movement, in part, because no widely adopted measurement tool exists. The International…

Biochemistry is a challenging subject because student learning depends on the application of previously learned concepts from general chemistry and biology to new, biological contexts. This article describes the development of a multiple-choice instrument intended to measure five concepts from general chemistry and three from biology that are…

In the area of large scale assessment, there is increasing interest in the measurement of students' written performance. At issue is whether the task demands in writing assessment can be simplified to involve the production of paragraph-length writing samples and/or multiple choice testing, rather than full-length essays.

A study was conducted to assess the validity of translations of two different forms of a licensing examination for cosmetologists in Florida to ensure that both Spanish and English candidates have equal chances of being licensed. The LISREL computer program was used to test the equivalence of factor structure, units of measurement, and standard…

The purpose of this study was to determine whether option weighting improved the internal consistency and intercorrelation of the subtests. The differential option-weighting scheme employed in this study is based on one devised by Guttman. The tests were first scored with Guttman-type weights and then with conventional correction-for-guessing…

Factor analysis was used to determine whether computerized patient management problems had the same factor structure as multiple choice examinations and rating scales. It was determined that the factor structure was similar to the examinations but not the rating scale. (JKS)
