<p style="text-align: justify;">Research on students’ perceptions of scientists is ongoing, starting with early research by Mead and Metraux in the 1950s and continuing in the present. Continued research interest in this area is likely due to scholarship suggesting adolescents’ impressions of scientists are sourced in-part from media, which influence their interests in science and identity in becoming a scientist. A significant source of images, in which adolescents (or middle school students) view science and scientists, is in their science textbooks. A qualitative content analysis explored images of scientists in three of the major U.S.-based middle grade science textbooks published in the new millennium: sixth grade biology, seventh grade earth science, and eighth grade physical science. The Draw A Scientist Test (DAST) Checklist was employed to assess scientists’ images and the stereotypes therein. From nine textbooks, 435 images of scientists were coded and analyzed by publisher and grade level / area by DAST constructs of appearance, location, careers, and scientific activities. Statistical analyses showed significant variances between grade levels and textbook publishers of scientists. Despite scientists portrayed in active endeavors, traditional tropes of the scowling, older, solitary, white male scientist persist. This study offers insight in leveraging improved images of scientists in textbooks.</p>

Increased academic course taking was a major goal of the education reforms of the 1980s, and increased graduation requirements were the most common change in state policies. This study analyzes transcript data on changes in course taking among graduates of high schools enrolling mostly lower achieving students in four states adopting high graduation requirements during the 1980s. The changes that occurred must be counted at least a moderate success. Average credits per student increased in all academic subjects, and the level of difficulty of these courses also increased. Science was the biggest gainer of the 1980s, with growth primarily in beginning academic courses such as physical science, earth science, and chemistry I. The usefulness of the kind of data reported in this article to policy-making and the difficulty of collecting such data strongly support the need for systematic indicators of course taking coded by level of difficulty and disaggregated by administrative unit (nation, state, district, school).

‘From whence to whither?’ discusses two examples that illustrate the role of plate tectonics in topics related to society and science: the recurrence of great earthquakes and the link between plate tectonics and glaciation. It also considers how plate tectonics has affected the way questions are approached in Earth Science. Has plate tectonics facilitated the discovery and acquisition of petroleum resources and ore deposits? Can plate tectonics be observed on other planets? Plate tectonics accelerated a shift from geology being a largely descriptive science aimed mostly at the history of our planet to a quantitative physical science focused on the processes that have made the present-day Earth what it is.

This chapter continues with CBM Elements and the design factors related to the science of culture. The following design factors are covered in this chapter: Cultural anomalies, Cultural cultures, and Cultural futures. This section, the science of culture, draws from key concepts in the fields of physical science, biological science, earth science, ecology, futures research, and crosscultural studies to explore the scientific nature of humanity and the possibilities of cultural futures. The science of culture seeks to assist human beings in adapting to their environment so that living can be achieved. This scientific way of thinking cuts across the natural, cultural, social, physical, and biological. Science is one of many ways of interpreting human reality (White, 1949).
