Investigated are the context dependency and construct validity of practical skill assessment in science which may include the skills of observing, manipulating, planning, interpreting, reporting, and self-reliance. Pupil performance on a variety of practical tasks were compared with external examination grades in biology and chemistry. (CW)

Presented is a criticism of the instructions given for and the scoring of the Draw-a-Scientist test (Chambers, 1983). A response to this criticism by authors who employ this method is included. (CW)

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…

Reported is a study in which secondary school students assessed their teachers for characteristics of effective science teaching. It was shown that the instrument used was highly valid and reliable and that secondary school students could effectively assess their teachers' pre-classroom characteristics, teaching behaviors, personality, and…

Presents study findings which supported the use of answer-until-correct tests. Discusses results based on responses of secondary students from England (N=387) that revealed that the answer-until-correct test of mechanical reasoning had similar findings to the spatial reasoning test. (ML)

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…
