The purpose of this article is to address a major gap in the instructional sensitivity literature on how to develop instructionally sensitive assessments. We propose an approach to developing and evaluating instructionally sensitive assessments in science and test this approach with one elementary life-science module. The assessment we developed…

Beginning with a reference to living in a time of both uncertainty and opportunity, this article presents a discussion of key areas where shared understanding is needed if we are to successfully realize the design and use of high quality, valid assessments of science. The key areas discussed are: (1) assessment purpose and use, (2) the nature of…

The PISA assessment instruments for students' scientific literacy in 2000, 2003, and 2006 have each consisted of units made up of a real world context involving Science and Technology, about which students are asked a number of cognitive and affective questions. This article discusses a number of issues from this use of S&T contexts in PISA…

In the wake of an increasing political commitment to evidence-based decision making and evidence-based educational reform that emerged with the No Child Left Behind effort, the question of what counts as evidence has become increasingly important in the field of science education. In current public discussions, academics, politicians, and other…

This article introduces the essential features of the science component of 2006 Program for International Student Assessment (PISA). Administered every 3 years, PISA alternates emphasis on Reading, Mathematics, and Science Literacy. In 2006, PISA emphasized science. This article discusses PISA's definition of scientific literacy, the three…

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)

Discusses the gender differences revealed on the science content items of the National Assessment of Educational Progress Science Assessment. Examines explanations for the differences, including differential prior instruction, differential response to uncertainty, differential response to figurally presented items, and different attitudes toward…
