Describes a teacher's system for rotating chemistry laboratory exercises in an effort to teach the basic laboratory techniques with a minimum of equipment. Outlines the basic techniques and procedures taught during a two-week rotation schedule. Lists advantages of this approach and guidelines for scheduling. (TW)

Describes two demonstrations used in laboratory chemistry courses. Discusses a "pH-activated" display used to chemically and visually supplement lecture demonstrations. Outlines another demonstration designed to show that copper(II) chloride is made of two ions, blue and yellow, which are combined to produce green. (TW)

The American Association of Dental Schools' guidelines for curriculum development in fixed prosthodontics outline the scope of the subject, interrelationship with other subjects and specialties, primary educational goals, prerequisites, core content, specific behavioral objectives for each subarea, sequencing, and faculty requirements.

The 15 conference papers in this report address a variety of issues such as computer applications in mechanics and optics, three-dimensional representation in physics teaching, computers in the physics laboratory, information technologies, the perceptual approach in physics education, improving students' conceptual understanding in physics, using…

This resource booklet is designed to supplement standard textbooks used in a science curriculum. The material serves as a syllabus for Year One and Year Two in the secondary science curriculum. Some of the topics presented in this general science syllabus include being a scientist, looking at living things, solvents and solutions, energy,…

Describes course on applications of computers to chemistry, computer-assisted instruction laboratory on measurement/error for high school chemistry, sample dispenser-computer grading system for quantitative analysis courses, and computer programs on nomenclature/preparations/reactions and least-squares refinement of pseudorotation parameters in a…

Presents chemistry experiments, laboratory procedures, demonstrations, and classroom materials/activities. These include: experiments on colloids, processing of uranium ore, action of heat on carbonates; color test for phenols and aromatic amines; solvent properties of non-electrolytes; stereoscopic applications/methods; a valency balance;…

Presented are physics experiments, laboratory procedures, demonstrations, and classroom materials/activities. Experiments include: speed of sound in carbon dioxide; inverse square law; superluminal velocities; and others. Equipment includes: current switch; electronic switch; and pinhole camera. Discussion of mechanics of walking is also included.…

Because advanced students had difficulty in interpreting cleavage patterns obtained by gel electrophoresis related to rapid sequencing techniques for DNA and RNA, several formats were developed to aid in understanding this topic. Formats included print, print plus scrambled print, interactive computer-based instruction, and high-resolution…

Describes laboratory procedures, demonstrations, and classroom activities/materials, including rapid peat-depth surveying; leaf-flotation method for measuring photosynthesis, an educational game demonstrating basis of protein synthesis, daffodil phototropism; chromatography apparatus; egg white digestion, and chromatography apparatus. Also…

Describes the preparation of selected aldehydes and ketones, alcohols, amines, phenols, haloalkanes, and tertiaryamines by differential scanning calorimetry. Technique is advantageous because formation of the reaction product occurs and the melting point of the product is obtained on the same sample in a short time with no additional purification…

Describes a series of laboratory experiments and computer simulations of the motion of electrons in electric and magnetic fields. These experiments, which involve an inexpensive student-built electron gun, study the electron mean free path, magnetic focusing, and other aspects. (Author/HM)

Describes a laboratory technique for use in an undergraduate instrumental analysis course that, using the interpretation of window diagrams, prepares a mixed liquid phase column for gas-liquid chromatography. A detailed procedure is provided. (BT)

Describes a laboratory experiment for freeze-drying fruits and vegetables which aims to expose college students to the principles of drying and simultaneous heat and mass transfer. The experimental apparatus, procedure of the experiment, and data analysis are also included. (HM)

Describes a dental teaching strategy that promotes acquisition of psychomotor skills through use of metacognition and problem-solving. In five steps, questions are asked to guide the learner through a sequence of discriminations leading to recognition of problems and solutions. Clearly defined criteria in a sequence reflecting procedure are…
