Guidelines for maintaining indoor air quality in schools with HVAC air cleaning systems are provided in this document. Information is offered on the importance of air cleaning, sources of air contaminants and indoor pollutants, types of air cleaners and particulate filters used in central HVAC systems, vapor and gas removal, and performance…

An overview is provided of the principles of cognitive psychology that can be used to enhance the effectiveness of computer-assisted instruction (CAI). First, the paper looks at the features of classical and operant conditioning that provide the foundation for important parts of mastery learning and CAI programs. Next, findings from four areas of…

This document presents an outline for a 135-hour course designed to provide the student with all the foundations necessary to become employable in the automotive air conditioning and heating trade. The course of study includes an orientation to the world of work, the elementary physics of air conditioning and heating, and laboratory experiments…

Article confined itself to criticism of the previous article in this journal and commented on three points: first, the need for the term autocontingency, second, contingencies and their subtlety, third, that fixed conditioned stimulus may mean that time since CS onset is a predictor of CS offset.

The diverse effects of light on plants and animals are reviewed in general. The conditioned behavior of fruit flies is also discussed. For the second article in this series, see SE 511 548. (DT)

Galvanic skin conductance response, respiration rate and respiration depth values of an experimental and control group were used to test the hypotheses of a Albert Ellis' ABC Theory of psychopathology. (EK)

The notion of differentially reinforcing low rates of undesirable behavior (DRL) is examined. Further, the status of the full session DRL strategy as alternative to punishment is questioned in context of a strictly operant definition of punishment. A reexamination of the data from some studies reveals the possibility that Ss respond to said DRL…

The Lennox single package all-season rooftop unit and mounting frame is described in detail. This piece of equipment is designed primarily for rooftop installation with bottom handling of conditioned air. In addition, an installation with end handling of conditioned air makes possible three air distribution patterns. Areas discussed are--(1) unit…

The differences between the authors of the Coleman report and their critics make clear why the effectiveness of schools will always remain controversial as long as inferential statistics are employed to determine it. Controversy is inevitable when measurement requires the satisfaction of assumptions antithetical to the teaching processes through…

Research was conducted on two selective attention systems in learning situations. The theoretical and experimental approaches are presented in a set of six papers. One paper considered directions in attention theory and five papers report experiments with pigeon and children subjects. The two attention systems are (1) coding response, which…
