A CATEGORY SYSTEM FOR THE DESCRIPTION AND ANALYSIS OF TEACHER-PUPIL INTERACTION IN HIGH SCHOOL BIOLOGY CLASSES WAS DEVELOPED. IN THE FIRST PHASE, A HETEROGENEOUS SAMPLE OF TEACHERS AND SCHOOLS WAS USED FOR OBSERVATION AND DEVELOPMENT OF THE CATEGORY SYSTEM. OBSERVATIONS WERE MADE OF LECTURE AND LABORATORY SESSIONS, VERBAL AND NONVERBAL CLASSROOM…

Encourages use of case studies to introduce "real-life" engineering assignments, suggesting that they should be given in a natural order as a series. Describes three such assignments being used at the University of the West Indies. Description, analysis, and design of an existing engineering system is included. (JM)

Presented is an analysis of think-aloud protocols of graduate students solving several different tasks in organic chemistry. The systems used by these subjects were classified. It was reported that the methodological system was most often used. (CW)

This study applies the methodology of systems dynamics to analyze engineering and engineering technology education systems. A preliminary system analysis is presented relating primary variables and their interaction in the overall system through a series of feedback loops. This is followed by a system structure development and mathematical…

Discusses the use of simulations to study complex real-life systems in engineering. Describes some of the limitations of using simulations. Identifies some situations in which computer simulations are practical and useful tools for the design, analysis, and evaluation of systems. (TW)
