Describes an experiment which uses the Gran plot for analyzing free ions as well as those involved in an equilibrium. Discusses the benefits of using Gran plots in the study of acids, as well as other analytes in solutions. Presents background theory along with a description of the experimental procedures. (TW)

Describes a two-week concentrated laboratory course in chemistry offered by Union College (New York) for middle school students. Provides the objectives of the course and a listing of experiments done by the students. Promotes the use of experiential approaches rather than lengthy lectures and discussions. (TW)

Discusses the use of the Tangent Sphere Model (TSM) in introducing chemical structure to beginning chemistry students at both the secondary school and college levels. Describes various applications of the use of such models, including instruction of the atom's kernel and valence electrons. (TW)

Describes three teaching activities used in the Chemistry for Kids program which focus on how esters are chemicals partially responsible for the flavor of foods. Includes a discussion of a demonstration involving role-playing, a set of taste tests, and an activity using chewing gum to investigate odors in food. (TW)

Describes the field work component of a half-term course in environmental chemistry. Discusses the teaching methods used with the students in detecting water pollution. Outlines the activities and experiments in one field trip and presents the results and deductions made by the students. (TW)

Covers use of cryogenic fluids, discussing physical properties, hazards to personnel, flammability, storage, transfer, and disposal. (JM)

A survey of medical, law, and chemistry and psychology graduate students' perceived stresses (academic activities, personal relationships, time pressures, and financial concerns) contradicted the expectation that medical students' stress level would be highest. Time restrictions and economic and academic issues produced the highest stress. (MSE)

In this study, prospective science teachers' (PSTs) views about their poster presentations were investigated. These posters were developed through PSTs' online and library research and scientific mini-symposiums in chemistry related topics in the framework of science, technology and society course (STS). During the first four weeks of STS course,…

This paper discusses the role of high school chemistry teachers' beliefs in implementing computer visualization software to teach atomic and molecular structure from a quantum mechanical perspective. The informants in this study were four high school chemistry teachers with comparable academic and professional backgrounds. These teachers received…

Describes a six-week organic chemistry course developed for gifted elementary students. Includes discussion of course activities and syllabus of course experiments and demonstrations. An informal evaluation and exam results indicate that the course was successful. (JN)

Evaluates textbook content in light of goals set forth by the National Science Teacher's Association Project Synthesis. Examines the history of textbook change over two decades in comparison to CHEM Study 1963. Summarizes major features of texts that promote memorization at the expense of understanding. (JM)

Reviews the development of locally produced instructional television to supplement curriculum, emphasizing that programs must be designed to illustrate/augment a particular course's material. Describes required equipment, setup, preproduction planning, taping (sample script available), and provides results of student evaluation of instruction and…

Preparation for college or life, working conditions and continuing education for high school chemistry teachers, and form/function of high school chemistry textbooks were addressed in presentations at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982). Workshops, lectures, and demonstrations were also presented to…

Reviews two areas of concern in precollege science and mathematics education: (1) public ignorance of mathematical, scientific, and technological phenomena and (2) shortage of individuals competent and willing to teach science/mathematics. Focusing on the latter, includes comments (with possible solutions) from science educators, politicians, and…

Peer interaction combined with the use of concrete models and analogs found to enhance learning (cognitive and affective) for both formal and nonformal operational students (N=51). Instruction in control class was based on lectures, CHEM study laboratories and individual work. (Author/SK)
