Reports on the design and testing of student-directed investigations for use in large enrollment biology courses. Describes a set of experiments that include the preparation and study of the enzyme tyrosinase. (DDR)

Details a lesson that utilizes trigonometric identities to determine the optimal angle between the atoms of covalent bonds. Generates a proof of the optimal angle for a molecule with four identical atoms bonded to a central atom that has a complete valence shell. (DDR)

Saccharomyces cerevisiae provides an excellent tool for students to enter into inquiry-based science. This very simple organism is used to demonstrate that the principles governing life apply to all organisms. Students learn to design experiments using trypan blue and heat, build upon their findings with new experiments, and refine and repeat…

Describes some problems of classroom dissection including the cruelty that animals destined for the laboratory suffer. Discusses the multilevel approach that the National Anti-Vivisection Society (NAVS) has developed to address the problems of animal dissection such as offering a dissection hotline, exhibiting at science teacher conferences, and…

Provides an exercise designed to give students an appreciation for the genetic basis of behavior. Employs the phenomenon of glucose aversion as an example of evolution by mutation and accelerated natural selection, thereby revealing one of the ways in which organisms adapt to human interference. (DDR)

Describes a health-and-safety risk-management audit in four Queensland, Australia high schools. One major outcome of this research project is the development of a comprehensive risk-management policy in compliance with the law. Other outcomes include the preparation of a professional-development package in risk-management policy for use as a…

Describes the redesign of the first semester general chemistry laboratory at the college level. An organic component is included in the redesign and it provides students with explicit examples of several types of operations in which chemists engage. Contains 16 references. (DDR)

Examines the effects of investigative, open-ended, and inquiry-based labs on students' ability to ask high-level and open-ended questions. Recommends combining direct instruction in questioning with increased background information to improve students' questions. (Contains 19 references.) (YDS)

Shares knowledge about the administrative audience, what the authors wish they had known when they were directors of writing centers and writing programs. Addresses how they could have negotiated for more dollars, more space, more options for expanding and improving services. Notes that administrators are part of the institution and can be…

Examines the relationship between the foremost writing program director at a college or university and the writing center director. Compares the nature and status of the two positions and the background of the people who hold them. Finds program directors enjoy a more privileged place in institutional structures and that the professionalization of…

"How the World Works" is an interdisciplinary science and mathematics course in which students design and perform their own experiments, analyze the data, and present their results orally and in writing. Evaluations indicate that most students learn how to do science and gain a better appreciation for science as a process. (SAH)

Examines Photo CD as a possible standard storage medium. Functionality within the system is explored, including future-proofing implications and application hints for practitioners; two case studies illustrate typical applications, one at the University of Aberdeen (Scotland) and one at a commercial image archive laboratory. (Author/LRW)

Describes a series of 14 hands-on, low-cost exercises in plant sciences developed to support biology teaching and maintain student interest. Each exercise includes education objectives, biology background, detailed procedures, and topics to stimulate discussion and critical thinking. (DDR)

Argues that misunderstanding about the purpose of the salt bridge probably arises from a lack of explicit and adequate information in textbooks. Suggests a detailed teaching approach that describes the purpose of the salt bridge on the microscopic level. (DDR)

This study of computer laboratory courses at Curtin University of Technology (Western Australia) focused on whether students' perceptions of the computer laboratory environment are associated with achievement and attitudes towards computers and the course. Describes use of the Computer Laboratory Environment Inventory and the Attitude to Computers…
