The dimensionality of attitude scales: a widely misunderstood idea

Summated rating scales to measure attitudes (and other human characteristics) commonly consist of numerous items whose scores are summed to yield a total score. A central assumption underlying the use of this technique is that the items in the scale reflect a common construct. If this assumption is not met, the scoring procedure produces largely meaningless, uninterpretable data. Although this important psychometric principle has been known for a long time, numerous studies in the research literature demonstrate a neglect of this principle. Some studies make no attempt at all to conceptualise the construct to be measured; others conceptualise the construct but then ignore the possibility that it may be multi‐dimensional; still others actually contain evidence which indicates that the construct is multi‐dimensional and then proceed to ignore that evidence. A possible contributor to the confusion is the widespread misunderstanding about the related yet distinct concepts of internal consistency and uni‐dimen...

Technology Education in Ontario: Evolution, Achievements, Critiques and Challenges. Part 1: The Context

This article, in seven sections, describes the evolution of technological education in the Canadian province of Ontario. The first section clarifies the meanings of the terms technology and technological education. The second outlines significant events in the history of technical education in the province. The third examines some of the societal factors that have created a climate for change during the past two decades, while the fourth describes the broader context of recent curriculum developments. The fifth reports on the introduction in 1995 of The Common Curriculum and the publication of Broad-based Technological Education. The sixth provides a few case studies illustrating the variety of ways in which technology education is currently implemented. The seventh section offers an evaluation and critique of some aspects of provincial curriculum policy and practice. The article is published in two parts. Part 1, in this issue, contains the first five sections, which describe the current curriculum offerings and their evolution. Part 2, containing the remaining two sections and all references, will be published in the next issue.
