Introduces an integrated unit on scuba science. Studies oxygen in kinetic theory, Boyle's law, Charles's law, Dalton's law, human circulatory and respiratory systems, and diving dangers such as decompression sickness. (YDS)

Describes a university course on natural history in which undergraduates and K-12 teachers make four Saturday field trips to observe local natural history. Undergraduates practice carefully and objectively describing the landscape while K-12 science teachers learn about the local geology and ecology that they teach in their earth science, biology,…

Explains the procedure for creating a field guide for high school students. Provides field guide questions and a sample format of the guide's insect page. (YDS)

Explains how students can perform an alternative authentic DNA fingerprinting analysis. Presents restriction fragment length polymorphism (RFLP) analysis and can serve as a simulated molecular epidemiology laboratory or as a simulated forensic laboratory exercise. (DDR)

Explores the relationship between three psychological factors (1) field dependence/field independence; (2) convergent/divergent dimensions of cognitive styles; and (3) working memory capacity and their effect on word association test responses for biological concepts, as well as grid questions. States the research study was completed in three…

Investigates the prevalence and antecedents of burnout in a large sample of school psychologists from North Carolina. Approximately 40% of school psychologists reported high levels of emotional exhaustion, 10% reported depersonalization reactions, and 19% reported a reduced sense of personal accomplishment. Results suggest personality variables…

Describes the development, preparation, and use of a medium that can select against a wide variety of Gram-negative bacteria while still allowing growth and differentiation of a wide range of Gram-positives. (WRM)

Describes a simple, inexpensive modification that changes a brightfield microscope into a darkfield microscope, allowing low-contrast samples to be examined. (WRM)

Describes the construction and use of an inexpensive, portable photometer designed specifically for estimating population sizes in yeast cultures. Suggests activities for use with the photometer. (WRM)

Criticizes introductory biology texts for merely describing living things in terms of what they can do as whole organisms and neglecting to consider the nature of life on a micro-scale. Presents possibilities for including such discussions in an introductory biology course. Contains 14 references. (WRM)

Describes a method of presenting Greek and Latin root words in order to teach biological terminology. Presents a sample root word list and related activity. (WRM)

Discusses the importance of assessment in the enhancement of learning. Explains different types of assessment such as performance assessment, portfolio assessment, time-series assessment, and the predict-and-explain assessment and discusses how to analyze assessment. (YDS)

Viewing alcoholism in women from a biopsychosocial perspective reveals a unique set of circumstances and challenges that women alcoholics face when compared with men. Biologically, women react differently to alcohol ingestion than do men. Women reach higher blood alcohol levels and sustain more somatic and cognitive damage than men when consuming…

Conducting observational investigations of behaviors and processes is an important method for generating scientific knowledge. This article describes a methodology for assisting students in the processes of observational inquiry and theory articulation and its instantiation in a set of digital video tools. We describe a high school biology…

In this article, the author talks about an inquiry-based activity involving yeast, wherein students learned about cell size. The activity allows students to employ math connections and to learn experimental techniques while practicing microscope skills. The activity can be adapted for students at all levels of biology. The author presents details…
