The Construct Validity of an Examination Designed to Test Practical Ability in Biology.
Peer reviewed Peer reviewed
Brown, C. R.; Njabili, A. F. – Research in Science and Technological Education, 1989
Explores the concept of construct validity in the context of a public examination. Multitrait-multimethod analysis and factor analysis were used. Discusses the analyses in terms of theory versus practical components and experimental versus observational investigation in practical components. Sample items for the practical examinations are…

Two Different Methods of Assessing Practical Skills at an Advanced Level Examination in Biology: Demonstration of Construct Validity or the Appraisal of Non-Events?
Peer reviewed Peer reviewed
Brown, C. R.; And Others – Research in Science and Technological Education, 1992
Scrutinizes the assessment of students' practical skills, in an honors-level biology examination, for construct validity utilizing both correlational and factor analytical methods to explore relationships between students' practical (laboratory) and theoretical (written) performances. Indicates that teacher assessment of practical skills resulted…

The Validity of Project Assessment in an Advanced Level Biology Examination.
Peer reviewed Peer reviewed
Brown, C. R.; And Others – Research in Science and Technological Education, 1995
Assessment of practical objectives by means of a project which occurred in an operational Advanced level examination in the United Kingdom is analyzed for construct validity. As in previous research, low correlation were found between scores of (n=218) candidates on the project and on the other components of the examination. (18 references)…

Construct Validity and Context Dependency of the Assessment of Practical Skills in an Advanced Level Biology Examination.
Peer reviewed Peer reviewed
Brown, C. R.; Moore, F. L. – Research in Science and Technological Education, 1994
Analyzes construct validity of two different methods of assessing practical skills in advanced level biology by considering how candidates' scores on practical objectives relate to each other and to those on theory papers. Differences were found in the interrelationships among scores of the two methods. (ZWH)
