1, 2, 3, 4: Infusing Quantitative Literacy into Introductory Biology

Biology of the twenty-first century is an increasingly quantitative science. Undergraduate biology education therefore needs to provide opportunities for students to develop fluency in the tools and language of quantitative disciplines. Quantitative literacy (QL) is important for future scientists as well as for citizens, who need to interpret numeric information and data-based claims regarding nearly every aspect of daily life. To address the need for QL in biology education, we incorporated quantitative concepts throughout a semester-long introductory biology course at a large research university. Early in the course, we assessed the quantitative skills that students bring to the introductory biology classroom and found that students had difficulties in performing simple calculations, representing data graphically, and articulating data-driven arguments. In response to students'' learning needs, we infused the course with quantitative concepts aligned with the existing course content and learning objectives. The effectiveness of this approach is demonstrated by significant improvement in the quality of students'' graphical representations of biological data. Infusing QL in introductory biology presents challenges. Our study, however, supports the conclusion that it is feasible in the context of an existing course, consistent with the goals of college biology education, and promotes students'' development of important quantitative skills.     

Computational Efficiency through Visual Argument: Do Graphic Organizers Communicate Relations in Text Too Effectively?

Previous research on graphic organizers has found that they facilitate memory for corresponding text. This study investigated why one type of graphic organizer (a matrix) may communicate interconcept relations more effectively than an outline or text. In three experiments, college students judged the accuracy of interconcept relations after they read a text and studied a matrix, an outline, or the text again. We also measured students′ performance when study time was reduced and testing delayed. Results indicated that even when study time was reduced, viewing a matrix helped students make more accurate judgments of interconcept relations. We conclude that a matrix is more computationally efficient than an outline or text, enabling readers to compute interconcept relations more quickly and easily (Larkin & Simon, 1987), due to a communicative process called visual argument (Waller, 1981). However, this advantage disappeared when testing was delayed, which, ironically, may have been due to computational efficiency.     

Identification of Alcohol by Smell among Preschoolers: Evidence for Early Socialization about Drugs Occurring in the Home

This study tested preschoolers' ability to provide accurate verbal associations to alcoholic beverage odors and whether this ability was related to parental drinking patterns and motivations. Older preschoolers performed better than younger preschoolers; photographic cues improved performance; children who correctly identified a substance by smell had socially appropriate knowledge of the culturally appropriate users of the substance; children reported liking substances that are used mainly by children and adults, and generally reported disliking substances whose use is legally limited to adults only; children were better at identifying substances they commonly use, but success at recognition of alcoholic beverages was related to heavier parental drinking and use of alcohol for escape reasons. Findings have implications for theories of socialization to drug use and for models of prevention.

The Japanese University in Crisis

Japanese education has been a focus of comparative studies for the past 20 years. Many scholars have attributed the economic success of this industrialized society to a highly literate and well-educated population. Recent studies, however, have tended to be more critical of, in particular, Japanese higher education (HE). Indeed, most universities in Japan are acutely aware of the need for change and a considerable effort at institutional reform is sweeping the nation. Unfortunately most of the constructive criticism of Japanese HE has not yet been published in English. One of the most vocal of the reformists, Professor Ikuo Amano, has published widely on various aspects of HE in Japan. The following paper is a translation of a chapter in his book Challenges to Japanese Universities. This translation is prefaced by both a synopsis of this book as well as a brief introduction to Amano and his work.     

Initial Evidence on the Influence of College Student Engagement on Early Career Earnings

Using data from three waves of longitudinal surveys of the 2001 freshman cohort of the Gates Millennium Scholars (GMS) program, this study examined linkages between student engagement in college activities and early career earnings in the labor market. The results indicated that social engagement was positively related to early career earnings of college graduates while academic engagement was not. When considering students who majored in STEM fields versus those in non-STEM fields, results showed academic engagement to be positively related to early career earnings for non-STEM students but slightly negatively related to earnings in the labor market for STEM students. Social engagement was positive for graduates in the STEM fields but not significant for non-STEM students. Altogether, results show a complex relationship between student engagement and early career earnings. Implications for research and institutional policy are discussed.     

Using science songs to enhance learning: an interdisciplinary approach

Music is recognized as an effective mode of teaching young children but is rarely used in university-level science courses. This article reviews the somewhat limited evidence on whether and how content-rich music might affect college students' understanding of science and offers practical suggestions for incorporating music into courses. Aside from aiding memorization, songs may potentially improve learning by helping students feel relaxed and welcome in stressful settings, engaging students through multiple modes (verbal vs. nonverbal) and modalities (auditory vs. visual vs. kinesthetic) simultaneously, challenging students to integrate and "own" the material through the medium of song lyrics, and increasing students' time on task outside of class through enjoyable listening or songwriting assignments. Students may produce content-rich songs of good quality if given sufficient assistance and encouragement by instructors and peers. The challenges ahead include 1) defining the circumstances in which music is most likely to promote learning and 2) developing rubrics for evaluating the quality of songs.
