Theorizing progress: Women in science,engineering, and technology in higher education

A conceptual framework of positions on women in science, engineering, and technology (SET) was developed, showing a chronological progression of the main approaches to women's underrepresentation in SET during the past 20 years. Numerous initiatives have been advocated to address women's underrepresentation in SET in higher education. This article arose out of one such initiative, Winning Women, which was intended to help higher education in Scotland move toward good practice in this field. Two members of the project team describe their key findings and experiences. They illustrate how the underrepresentation of women in SET continues to be both progressive and persistent (using an SET parity index). The conceptual framework was conceived and developed from a metaanalysis of feminist theories of the gendered politics of science and technology. © 1999 John Wiley & Sons, Inc.

Print versus digital reading comprehension tests: does the congruency of study and test medium matter?

The use of digital environments for both learning and assessment is becoming prevalent. This often leads to incongruent situations, in which the study medium (eg, printed textbook) is different from the testing medium (eg, online multiple-choice exams). Despite some evidence that incongruent study-test situations are associated with inferior achievements, the effect of study-test congruency has not been investigated systematically. Here, we examine this question in the context of digitally displayed versus printed text comprehension using a full-factorial experimental design. One hundred and twelve university students participated in the study. They studied an expository text in one medium (print or digital) and then, comprehension was assessed in either the same (congruent) or the different (incongruent) medium. No significant differences in performance were found between the congruent and incongruent study-test conditions. However, consistent with findings reported in the literature, comprehension of the digital text was inferior to that of the printed text. Results show that this screen inferiority occurred irrespective of the testing medium. These findings suggest that studying in one medium and taking the test in another does not affect comprehension, but the medium in which one studies does influence test outcomes.     

Model‐based reasoning about energy: A fourth‐grade case study

We report a case study of model‐based reasoning in which a small group of fourth‐grade students analyzes the energy flow when a solar panel is used to power an electric motor that spins a propeller. In developing their explanation of energy flow, the students draw on a general model of energy developed collectively by their class in the course of an experimental classroom curriculum led by a trained teacher. They also construct a model‐based representation of the specific system under study. Their investigation and reasoning process exhibit all the features of authentic scientific model‐based inquiry, including the revision of their models to incorporate new information. In the course of their work the students recruit and seamlessly integrate nearly all of the practices of science designated in the Next Generation Science Standards. This case study provides an example of what modeling‐based teaching and learning can look like in an elementary school classroom. It also suggests that the study of energy offers a particularly promising context for developing students' use of science practices, especially the practice of developing and using models.
