Over the past decades, a large body of research has examined students' magnitudes of evolution acceptance and related measurement issues resulting in questions concerning instruments' validity and operationalization. Until now, several studies investigated validity aspects of often-used evolution acceptance instruments and came to diverging…

The aim of the present study is to enable future studies into students' attitudes toward science, and related constructs, by developing and validating an instrument suitable for cross-sectional designs. Following a thorough review of the literature it was determined that many extant instruments included design aspects that appeared to be limited…

This study developed an empirically based questionnaire to monitor young learners' conceptions of nature of science (NOS). The questionnaire, entitled Students' Ideas about Nature of Science (SINOS), measured views on theory-ladenness, use of creativity and imagination, tentativeness of scientific knowledge, durability of scientific knowledge,…

Agrees that the conceptual validity of the Scientific Attitude Inventory is suspect and a conceptual reanalysis of the distinction between "attitudes to science" and "scientific attitudes" is needed. However, inquiry into whether such instruments are developed consistently with formal criteria and theoretical guidelines of…

Examines some of the problems in interpreting data from attitude measures when the dimensionality of the instrument and sources of heterogeneity in the population are ignored. Illustrates this point by describing the development of an instrument designed to measure children's attitude toward science-related activities. (TW)

Discusses the complicating effects of ambivalence on the validity of science attitude measurement scales. Cites studies indicating that the positive and negative effects about a particular psychological object are not necessarily bipolar. Suggests the use of factor analysis to check dimensionality in instruments. (TW)

Describes a study designed to develop a systematic procedure for constructing a valid Likert attitude scale. Discusses the 15-step procedure that was produced. Reviews the resulting development of an instrument designed to test the attitude of teachers toward the use of microcomputers in the classroom. (TW)
