Exploring undergraduates' understanding of photosynthesis using diagnostic question clusters

We present a diagnostic question cluster (DQC) that assesses undergraduates' thinking about photosynthesis. This assessment tool is not designed to identify individual misconceptions. Rather, it is focused on students' abilities to apply basic concepts about photosynthesis by reasoning with a coordinated set of practices based on a few scientific principles: conservation of matter, conservation of energy, and the hierarchical nature of biological systems. Data on students' responses to the cluster items and uses of some of the questions in multiple-choice, multiple-true/false, and essay formats are compared. A cross-over study indicates that the multiple-true/false format shows promise as a machine-gradable format that identifies students who have a mixture of accurate and inaccurate ideas. In addition, interviews with students about their choices on three multiple-choice questions reveal the fragility of students' understanding. Collectively, the data show that many undergraduates lack both a basic understanding of the role of photosynthesis in plant metabolism and the ability to reason with scientific principles when learning new content. Implications for instruction are discussed.     

Using Virtual Field Trips to Connect Students with University Scientists: Core Elements and Evaluation of zipTrips?

Physical field trips to scientists?? work places have been shown to enhance student perceptions of science, scientists and science careers. Although virtual field trips (VFTs) have emerged as viable alternatives (or supplements) to traditional physical fieldtrips, little is known about the potential of virtual field trips to provide the same or similar science career exploration advantages as physical field trips. The overarching goal of this paper is to describe a VFT, zipTrips?, designed to provide middle school students, especially those in resource limited rural areas, with access to university scientists. Using zipTrips as a case example, the paper identifies and describes some of the core characteristics and elements of high quality authentic VFTs that foster student-scientist interactions. In addition, the paper uses program evaluation data to examine the impact of zipTrips on student perceptions of scientists.     

Te Wero—the challenge: reimagining universities from an indigenous world view

This paper provides a foundational framework to bring into conversation indigenous world views in reimagining universities. Highlighting a specific indigenous world view, the university is presented as a site for critical conversation and transformative praxis. We discuss the workplace experiences of indigenous staff in a university and infer from these how management practices related to indigenous staff could be enhanced. Building on our study of Māori academic and administrative staff in a New Zealand university, an indigenous typology and a Wero or challenge matrix is offered, which locates different positions and actions that universities adhere to or seek to emulate. The paper argues for universities to reimagine their policies and practices by drawing from the complex richness of indigenous world views.

Are first-circulation patterns for monographs in the humanities different from the sciences?

How many monographs acquired in a particular year circulate in that year? What percentage have their first circulation each successive year? Does the pattern differ for different broad subject areas, i.e., humanities, the sciences, and the social sciences? This article tests the assumption that the first-circulation pattern differs by subject. We conclude that the pattern does not differ. The finding is important for decisions about off-site storage, assessing collection development, maintaining departmental libraries, etc. Regardless of subject, if a book has not circulated at least once within a few years after acquisition, it is unlikely to find its reader.
