Biochemistry Instructors’ Views toward Developing and Assessing Visual Literacy in Their Courses

Biochemistry instructors are inundated with various representations from which to choose to depict biochemical phenomena. Because of the immense amount of visual know-how needed to be an expert biochemist in the 21st century, there have been calls for instructors to develop biochemistry students’ visual literacy. However, visual literacy has multiple aspects, and determining which area to develop can be quite daunting. Therefore, the goals of this study were to determine what visual literacy skills biochemistry instructors deem to be most important and how instructors develop and assess visual literacy skills in their biochemistry courses. In order to address these goals, a needs assessment was administered to a national sample of biochemistry faculty at four-year colleges and universities. Based on the results of the survey, a cluster analysis was conducted to group instructors into categories based on how they intended to develop visual literacy in their courses. A misalignment was found between the visual literacy skills that were most important and how instructors developed visual literacy. In addition, the majority of instructors assumed these skills on assessments rather than explicitly testing them. Implications focus on the need for better measures to assess visual literacy skills directly

Attitudes Toward Marriage, Partner Availability, and Interracial Dating Among Black College Students From Historically Black and Predominantly White Institutions

This study examined attitudes toward marriage, perceptions of partner availability, and attitudes toward interracial dating among Black male and female college students at two historically Black colleges/universities (HBCUs) and one predominately White institution (PWI). Most students had positive attitudes toward marriage, with women significantly more favorable than men. While both men and women reported insufficient romantic partner options, female students at PWIs were significantly more likely to report insufficient partner options than male students and those at HBCUs. Most students (72.6%) were favorable toward interracial dating, but males at HBCUs had more positive attitudes. However, students at HBCUs were more unsupportive of interracial dating than those at PWIs, and females at both types of institutions reported more unfavorable attitudes toward interracial dating than males. Findings reveal gender and contextual differences in attitudes and suggest a need for more nuanced studies of Black college student attitudes. </jats:p
