Selecting Books for Children Birth Through Four: A Developmental Approach

The selection of books to read to young children matters enormously in the role books play for enriching children’s lives. This paper reviews the scientific evidence for the appropriate selection of books, and argues that care in selecting books targeted to children’s developing skills will enhance the power and the pleasures of reading to young children.     

Computer-supported aids to making sense of scientific articles: cognitive, motivational, and attitudinal effects

High school students can access original scientific research articles on the Internet, but may have trouble understanding them. To address this problem of online literacy, the authors developed a computer-based prototype for guiding students’ comprehension of scientific articles. High school students were asked to read an original scientific research article about the effects of drug or alcohol abuse, which was presented on a computer screen either with computer-based comprehension aids or without aids. The aids provided background text and animations including answers given by the article authors. Across two experiments involving different schools and different research articles, the comprehension aids group performed better than the control group on a comprehension test concerning the article (d = +0.79 in Experiment 1 and d = +0.82 in Experiment 2) and rated the content of article as less difficult to read (d = +0.96 in Experiment 1 and d = +0.69 in Experiment 2). In addition, the comprehension aids group reported more positive motivational beliefs than the control group concerning understanding what scientists do (d = +0.51 in Experiment 1 and d = +0.56 in Experiment 2), appraising the article as worthwhile (d = +0.80 for Experiment 1 and d = +0.70 for Experiment 2), and being interested in reading another research article (d = +0.19 in Experiment 1 and d = +0.58 in Experiment 2). The groups did not differ on their attitudes concerning a career as a scientist or about alcohol and drug abuse. Overall, computer-based comprehension aids can help guide students’ comprehension processes for an original scientific research article, which in turn can improve their appreciation of what scientists do.

The Status of Genetics Curriculum in Higher Education in the United States: Goals and Assessment

We review the state of genetics instruction in the United States through the lens of backward design, with particular attention to the goals and assessments that inform curricular practice. An analysis of syllabi and leading textbooks indicates that genetics instruction focuses most strongly on foundations of DNA and Mendelian genetics. At the same time, a survey of faculty indicates that other concepts, such as the application of genetics to society or the environment, are viewed as equally or even more important than foundation concepts. This disconnect suggests a need for more explicit goal setting prior to curriculum development. We also review the relationship between concept inventories, multiple-choice tests measuring conceptual understanding, and curricular goals. Existing concept inventories offer a strong foundation on which to build community-developed concept assessments of genetics knowledge. Concept assessments such as these would allow the genetics education community to test hypotheses of curricular change.
