Laboratory work in chemistry has been extensively researched in the last decade but the gap between research and practice is still broad. This "Perspective" shares 10 guiding principles relating to university laboratory education, drawing on research over the last decade. Written with an audience of practitioners in mind, the…

The study aimed to determine the effects of students teams achievement divisions (STAD) and reading-writing-application (RWA) methods on teacher candidates' academic achievements, laboratory attitudes, cooperative work, laboratory safety and scientific process skills in science teaching laboratory practice-I courses. In the research, a…

Excellent film is an integrated art. It has rich knowledge and profound ideological connotations. In order to promote students' enthusiasm for learning about biology, we made some attempts on how to use movie clips for biological teaching and achieved good results. Making use of movie's sound, color, light, and animations, we tried to enrich…

The antibacterial chemical triclosan is a common component in personal care products but recently the subject of many reports concerning environmental toxicity and health impacts. Although triclosan concentration in a soap can be determined simply via high-performance liquid chromatography, this is a technique not routinely available in the…

Introductory experiments of chromatography are often conducted by separating colored samples, such as inks, dyes, and plant extracts, using filter paper, chalk, or thin layer chromatography (TLC) plates with various solvent systems. Many simple experiments have been reported. The relationship between normal chromatography and reversed-phase…

Stopped-flow kinetics techniques are important to the study of rapid chemical and biochemical reactions. Incorporation of a stopped-flow kinetics experiment into the physical chemistry laboratory curriculum would therefore be an instructive addition. However, the usual reactions studied in such exercises employ a corrosive reagent that can over…

The activities that introduce topics of chemical health and safety are offered, using student-centered cooperative method. Teaching methods and exercises used in various activities were considered valuable enough to be modified and published in a book of activities for safety.

Provides tips for stimulating interest in high school chemistry while imprinting safe laboratory practice. Suggests safe alternatives to potentially dangerous "magic show" and other chemical reactions. Also suggests that safety education be a prerequisite for certification of secondary school chemistry teachers. (Author/JN)

A final examination, review questions, and essay topics are provided. (CP)

Describes a procedure which identifies an experiment as unreasonably hazardous or indicates precautions to be taken rendering the experiment acceptable for assignment to undergraduate students. The procedure follows in parallel form the procedure used to prepare chemical labels. (Author/JN)

Describes the use of practice weighings and handling of fluorescent compounds to assist in teaching students safe-handling techniques. (PR)

Describes the prosecution efforts regarding a chemistry teacher when one of the teacher's students was injured in an explosion in an attempt to make gun powder. In a different section, discusses nonscientists in science laboratories and the responsibilities of competent persons. (PR)

Describes a two-quarter hour college chemistry course focusing on laboratory safety. Includes lists of topics/assignments, problem sets (toxicology, storage, and energy) and videotapes, films, and slide sets used in the course. (JN)

This manual was written as an aid to teaching assistants (TAs) who conduct the laboratory portions of life science courses at the University of Washington. In general, this manual does not present specific factual material. Rather, it offers suggestions on how to handle various teaching situations and provides a framework to use in many different…

A five-week course for fourth- and fifth-grade students (titled "Chemistry for Kids") was developed. Each class session consisted of a brief lecture, a demonstration, and one or more experiments. An outline of concepts fostered, instructional strategies, and procedures used is provided. (JN)
