Describes the intonation visualizer, a machine which permits a model sentence to be presented aurally to a student who sees simultaneously the intonation pattern being traced on an oscilloscope screen. The student then repeats the sentence and sees on the screen the intonation curve that he is generating. (Author/CFM)

The effectiveness of an educational program in decreasing utilization of the prothrombin time determination as a routine admission laboratory test by house staff physicians at a teaching hospital was studied. The results emphasize the need to measure the long-term outcome of educational programs aimed at modifying the clinical behavior of…

An experiment is described in which students in an introductory laboratory can determine all of the relevant energy flows of an ordinary household refrigerator. (Author/CP)

The programs of the Multi-Culture Institute focus upon increasing children's pride in their ethnic backgrounds; ethnic differences become a source of learning experiences for the children and community. (MM)

Describes apparatus utilized to demonstrate physics principle. Equipment described includes a low pressure chamber, a 360 degree loop ramp, a tilted table demonstrating motion principles, and a method for casting a three dimensional display of magnetic lines of force. (SL)

Two demonstrations are described. The first (useful as an introduction to kinetics) shows how the rate of a reaction is fast at first and then gradually decreases to zero when one reactant has been used up. The second is a gas density demonstration using 1,1,2-trichloro-1,2,2-trifluoro ethane. (JN)

Examination of relationships between manner of utilization of human and material resources and secondary school students' achievement in and attitude toward science found that frequency of use of laboratory resources had highest positive correlation with achievement, followed by quality of use of laboratory resources. Quality of use of laboratory…
