Describes a teaching method using computer probeware to enhance students' laboratory experiences. Discusses the role of computer probeware in the science classroom, how probeware affects learning, and how it affects efficiency. (KHR)

Presents a case study of an unsafe situation in a science laboratory and its administrative consequences. Discusses issues related to laboratory safety and faculty evaluation. (JRH)

Authors describe the origin of practical science in English school education and trace its history up until the end of the nineteenth century. Practical work by this time was held in high esteem by most science educators and was now regarded as an essential requirement for science teaching. (over 25 references) (Author/PR)

Describes the adaptation of thermite (aluminum with metal oxides) reactions from whole-class demonstrations to student-run micro-reactions. Lists detailed directions and possible variations of the experiment. (WRM)

Internet collaboration among laboratories allows scientists to work together at a distance, and will eventually enable researchers to examine microscope-produced images simultaneously and participate in meetings and seminars remotely. If the ventures succeed, the resulting technology will allow smaller institutions to cooperate more easily.…

Describes an activity in which teams of students locate laboratory safety equipment in a scavenger hunt contest. (WRM)

Presents an inexpensive activity to stimulate student interest in biotechnology that was developed in partnership with a biotechnology company. Focuses on the use of DNA by a commercial laboratory; describing the analysis procedure; important uses of DNA technology in modern society; and ethical, social, and legal issues related to biotechnology.…

Describes an activity that reduces the biosphere to a water-filled jar to simulate the relationship between cellular respiration, photosynthesis, and energy. Allows students in high school biology and related courses to explore quantitatively cellular respiration and photosynthesis in almost any laboratory setting. (ASK)

Explains the benefits of using plastinated specimens on students' conceptual understanding. Argues for dropping the dissection component from introductory biology courses due to threatened animal populations and the high cost of providing some of the specimens. Describes how to use plastinated specimens in an investigative laboratory approach.…

Investigates the effects of the Science Writing Heuristic (SWH) format on student's achievement, thinking abilities and motivation. Focuses on distribution equilibrium and assesses student understanding by studying metacognitive and practical factors. (Contains 17 references.) (Author/YDS)

Describes a science laboratory that plays an important role in making modern physics accessible to teachers, school classes, and individual students. Claims it is a resource and a complement to the traditional education system. (Author/CCM)

Summarizes the recent research on pollen germination and introduces some basic studies on pollen tube growth that can be conducted in a secondary school laboratory. Discusses the use of a light microscope and refrigerator to study pollen. (Contains 13 references.) (Author/YDS)

Science teachers who are committed to excellence in the classroom continually seek ways to improve teaching and learning, and the concept of multiple intelligences holds promise as a method for accomplishing this. The essence of the theory of multiple intelligences is to understand the many differences among students, the variations in the ways…

A bioinformatics laboratory exercise based on inherited human morphological traits is presented. It teaches how morphological characters can be used to study the evolutionary history of humans using parsimony. The exercise can easily be used in a pen-and-paper laboratory, but if computers are available, a more versatile analysis can be carried…
