Presents an activity to help students understand the precepts of the Hardy-Weinberg principle and simultaneously permit observation of a model of evolution through natural selection in a nonthreatening setting. (PR)

Describes a writing-across-the-curriculum course and its application to science courses. Shows how different kinds of writing instruction affect students' learning as well as students' attitudes, understandings, and approach to "writing to learn." (PR)

Explains that the use of data on CD-ROMs gives undergraduate students an economical way to work with real data on potentially publishable projects. Describes a student project using the data on the World WeatherDisc to find evidence of Indian Summer in Spokane, WA. (PR)

Describes a study of factors in the development of reasoning on the balance beam (n=34 nonscience majors in a Physical Science class). From this study and others, the author developed a model of problem solving and problem-solving behaviors. The implications of this model for instruction are discussed. (PR)

Describes a laboratory exercise that takes advantage of the abundant number of species of goldenrod galls that exist in the environment to explore a question concerning the behavior of the female gall-forming insects as they lay eggs on the goldenrod plant. (ZWH)

Structural equation modeling using the LISREL VI program was used to investigate predictors of female university students' participation in mathematics and science courses. Contributing significantly to the model were self-perceived mathematical ability, quality of experience in mathematics and science courses, importance to self-concept of…

Discusses the need for college science teachers to show students the fundamentals before expecting them to "dive in." Argues for the importance of homework in post-secondary science classes. (WRM)

Educational technology supports meaningful learning and enables the presentation of spatial and dynamic images, which portray relationships among complex concepts. The Technology-Enabled Active Learning (TEAL) Project at the Massachusetts Institute of Technology (MIT) involves media-rich software for simulation and visualization in freshman…

The ability to negotiate and resolve socioscientific issues has been posited as integral components of scientific literacy. Although philosophers and science educators have argued that socioscientific issues inherently involve moral and ethical considerations, the ultimate arbiters of morality are individual decision-makers. This study explored…

The objectives of this study are: (a) elaboration of a history and philosophy of science (HPS) framework based on a reconstruction of the development of the periodic table; (b) formulation of seven criteria based on the framework; and (c) evaluation of 57 freshman college-level general chemistry textbooks with respect to the presentation of the…

The model organism, "Caenorhabditis elegans," in addition to being well suited to genetics and cell biology teaching applications, can also be useful in the physiology laboratory. In this article, the author describes how students in a junior level college Comparative Physiology course have made use of "C. elegans" in semester-long,…

This study sought to unpack how immigration is associated with youths' educational choices during the transition to college and adulthood. Surveys and school records were collected on 789 youth (ages 1825) with Asian Pacific, Latino, African/Afro-Caribbean, and European backgrounds. The results indicated generational differences in educational…

Of all the sciences, biology has probably made the most rapid progress in recent years and the need for this to be reflected in a new Advanced Level biology course has long been recognised in the UK. After wide-ranging consultation and successful piloting in over 50 schools and colleges in England and Wales, the new Salters-Nuffield Advanced…

We report on a study of what happened when we recycled a conceptual examination question in a first-year university physics course. The question, which was used for three consecutive years, asked about an astronaut's experience of weighing in an orbiting space-craft. The original intention was to use a phenomenographic approach to look for…

The development and use of computer assisted learning (CAL) materials in the life sciences is well established and, in the UK at least, significant resources have been provided to enable this. Some years on from when the major investments took place teachers are facing the problem that the technologies used to develop and deliver the CAL programs…
