A device is described to assist in designing prototype interfaces between a minicomputer and an external device. This device is especially useful in undergraduate student projects, where time is limited. (BB)

Traces chemistry education in British secondary and higher education from the beginning of the 20th century to the present. Classical education ignored chemistry and other physical sciences. The space age of the 1950's dramatically increased interest in science study, but now funds are decreasing and chemistry is waning except in higher education.…

Describes a chemistry course with the goal of fostering a broader and deeper understanding of a few fundamental concepts through group discussion, instructor exposition, and participant-developed laboratory and demonstration activities. (DDR)

Describes a laboratory experiment for secondary school chemistry students utilizing the classic reaction between the iron(III) ion and the thiocyanate ion. The experiment also works very well in other chemistry courses as an experience in spectrophotometric analysis. (PVD)

Presents an activity that enables students to learn how to read a fertilizer label, to understand the components of fertilizers, and to compare natural and man-made fertilizers. Includes background information and student worksheets. (DDR)

Presents a science activity that enables students to carefully examine the root system of a plant and to understand that roots-specifically root hairs-are needed so that water and nutrients can be absorbed. Includes student data sheet and extension activities. (DDR)

Reports a study of the quality and extent of understanding of certain well-known theoretical concepts which are held by prospective teachers (N=173) of chemistry in Yemen. Results indicate that teacher understanding ranges from a partial understanding with a specific misconception to no understanding. Contains 25 references. (DDR)

Reports on an ethnographic study of laboratory sessions in the departments of Physics and Chemistry at the University of Natal in Durban, South Africa, with specific focus on the comparison of the function of verbs in three first-year laboratory manuals. Several pedagogical implications are discussed. (JL)

Provides details on the chemical composition of trees including a definition of wood. Also includes an activity on anthocyanins as well as a discussion of the resistance of wood to solvents and chemicals. Lists interesting products from trees. (DDR)

Reviews a subjective exercise completed by students at the end of each of six units in an introductory organic chemistry course. Argues that instruction should be shaped by Ausubel's concept of meaningful learning. (DDR)

Presents a unit that focuses on landslides and integrates earth science, physics, chemistry, and math. Includes activities to investigate porosity, permeability, cohesion, saturation, and gravity. (JRH)

Describes the Computer-Assisted Personalized Assignment (CAPA) system which offers a way to apply computers to assist instructors and students in the framework of lectures and assigned problem sets without students being forced to use the computer system. (DDR)

Describes four outreach programs that connect businesses and post-secondary institutions with schools and their science curricula. Mobile science laboratories provide services and access to science equipment to students and their teachers. (DDR)

Discusses the relationship between teaching and research in higher education and how they are sometimes one and the same. Provides a perspective on scientific literacy, thoughts on the role of scientists in talking with the public about science, and the rationale for making a video course about chemistry. (DDR)

Describes the recent history, chemistry, and educational uses of the Orange Juice Clock demonstration in which a galvanic cell is made from the combination of a magnesium strip, a copper strip, and juice in a beaker. Discusses the chemistry basics, extensions for more advanced students, questions for student/teacher workshop participants, and…
