The basic elective course in introductory botany is designed for secondary students who probably will not continue study in plant science. The objectives of the course are to help the student 1) identify, compare and differentiate types of plants; 2) identify plant cell structures; 3) distinguish between helpful and harmful plants; 4) predict…

The study was conducted to determine the influence of process-oriented television science on teacher and student process and concept achievement, classroom teacher process questioning, and the relationship between achievement and questioning behavior. Grades one through four were used for the study. Fifty-four volunteer teachers were randomly…

Discusses the current state of space-related research and manufacturing techniques. Focuses on the areas of spectroscopy, materials processing, electrochemistry, and analysis. Provides examples and classroom application for using these aspects of the space program to teach chemistry. (TW)

Discusses some difficulties presented by the use of clock reactions with large numbers of students in illustrating the determination of rate laws and the deduction of a mechanism. Suggests the videotaping of a clock reaction without narration to be used with students in stages so that observations can be recorded. (TW)

Reported is a survey designed to assess the relationship between essential competencies as perceived by faculty, and job needs as perceived by graduates of the agronomy department at Pennyslvania State University. Results indicated that while various competencies were valued differently, raters did not disagree on what were important competencies.…

Discusses the use of computer assisted instruction in the medical education program of the Kirksville College of Osteopathic Medicine (Missouri). Describes the animation techniques used in a series of simulations for microbiology. (TW)

Discusses some of the problems associated with teaching report writing to undergraduate chemical engineering students. Introduces a simplified cribsheet for writing formal reports and describes the Fog Index, which can be used to determine the sophistication of the writing. Includes a checklist for grading report writing. (TW)

Reports on a study which investigated the order of acquisition of intuitive notions of qualitative speed. Results indicated that an array of prerequisites, equivalent, and independent relationships existed among the tasks administered. Confirmed the evolution of reasoning for notions of qualitative speed found by Piaget. (Author/TW)

Describes how to construct a simple photometer. Outlines experiments in which this device can be used to demonstrate basic electronic principles, the use of Beer's Law to determine the concentration of an analyte in solution, and the effect of molar absorptivity on the sensitivity of photometric procedures. (TW)

Presents a topical outline for a course in chemistry for students in the health professions, as recommended for use by a committee of the American Chemical Society. States that there are several appropriate texts written for courses of this type. (TW)

Discusses some of the advances made by engineering educators in the development and use of instructional television (ITV). Provides suggestions on how new ITV satellite linkages between universities, industry, government laboratories, and technical societies can offer opportunities for faculty development. (TW)

Describes a statics course developed at Texas A&M University in the engineering curriculum which utilizes computer-assisted instruction. Discusses the organization and management of the team that developed the course, the selection of the hardware and software used, and the implementation model and lesson prototype developed for the course.…

Provides background information on rocks and minerals, including the unique characteristics of each. Teaching activities on rock-hunting and identification, mineral configurations, mystery minerals, and growing crystals are provided. Reproducible worksheets are included for two of the activities.
