This paper aims to clarify and discuss the reasons and limits of three rather popular metaphors that are used to speak of today's complex social and cultural fabric, through references to cultural anthropology, biology and genetics. In her analysis, the author considers not only the linguistic and semantic dimension of each metaphor, but also the…

Images, whether at the level of molecules, cells, organs, organisms, or environments, are at the core of many biological disciplines. Even with the contemporary emphasis on molecular analysis, biology has retained its traditional strong visual component. In courses that rely on the study of biological structure, the presentation of images for…

Pilocytic astrocytomas are WHO grade I gliomas that occur predominantly in childhood. They share features of both astroglial and oligodendroglial lineages. These tumours affect preferentially the cerebellum (benign clinical course) and the optic pathway, especially the hypothalamo-chiasmatic region (poor prognosis). Understanding the molecular…

Generic sentences (e.g., "Snakes have holes in their teeth") convey that a property (e.g., having holes in one's teeth) is true of a category (e.g., snakes). We test the hypothesis that, in addition to this basic aspect of their meaning, generic sentences also imply that the information they express is more conceptually central than the…

The purpose of this study was to reveal influential journals used by life scientists; journals not currently included in "BIOSIS Previews," but included in either "PubMed" or "Science Citation Index Expanded". These 252 journals were revealed by the Eigenfactor, an iterative ranking scheme which quantitatively measures the scientific influence of…

Terms to be familiar with before you start to solve the test: polymerase chain reaction, DNA amplification, electrophoresis, breast cancer, "HER2" gene, genomic DNA, "in vitro" DNA synthesis, template, primer, Taq polymerase, 5[prime][right arrow]3[prime] elongation activity, 5[prime][right arrow]3[prime] exonuclease activity, deoxyribonucleoside…

The purpose of this research is to explore a new computer-based interactive learning approach to assess the impact on student learning and attitudes toward science in a large university ecology classroom. A comparison was done with an established program to measure the relative impact of the new approach. The first inquiry project, BearCam, gives…

A new national curriculum has recently been implemented across Australia. This paper reports on a case study of a regional Western Australia government school as they re-wrote and taught the phase one learning areas: maths, English, science and HASS. Results showed what it is like to work in an environment where continual change is not only…

Three college faculty taught large general biology classes using case studies and personal response systems (clickers). Each instructor taught the same eight cases in two different sections, except the questions within the cases differed. In one section the questions were lower order (LO) factual inquiries, and in the other they were largely…

"Research Doctorate Programs in the Biomedical Sciences: Selected Findings from the NRC Assessment" examines data on the biomedical sciences programs to gather additional insight about the talent, training environment, outcomes, diversity, and international participation in the biomedical sciences workforce. This report supports an…

Aim: The aim of this study was to assess the quality of life (QoL) in patients with multiple sclerosis (MS), and to evaluate its association with disability and psychosocial factors especially depression and fatigue. Methods: Demographic characteristics, education level, disease severity, and disease duration were documented for each patient. QoL,…

The Plant Sciences Pedagogy Project conducted research into undergraduate teaching and learning in the Department of Plant Sciences at the University of Cambridge and has translated the research findings into interventions to improve support for student learning. A key research objective for the project was to investigate how teachers within the…

All medical and veterinary students at the University of Nottingham carry out a third-year dissertation module. This module allows students to spend time experiencing contemporary research methods by engaging in research activities. In 2010, academic staff from the Medical and Veterinary Schools initiated educational research projects that enabled…

Enrollment increases at many institutions have forced science faculty to reevaluate assessment decisions in light of increasing demands on time. Some have advocated the replacement of free-response examinations with forced-choice examinations as a time-saving strategy. The existing research literature contains many studies comparing student…

This column provides original articles on innovations in case study teaching, assessment of the method, as well as case studies with teaching notes. In this month's issue the authors describe an interdisciplinary approach to case study teaching that addresses the demand to balance the goals of process and content. The case study, Salem's Secrets…
