Section 3 of Phase II of the Pennsylvania Plan is concerned with the adequacy of the educational quality assessment instruments. An overall discussion of reliability--content, criterion related, and construct--is presented. Reliability coefficients for the assessment inventories are provided and empirical studies of validity are described. (PR)

Procedures are described which were used to develop an instrument and scale to measure an individual's ability to detect and describe the immediate affective state of another. Data are presented indicating the scale's reliability and the extent of the scale's content, concurrent, and predictive validity. (Author)

This paper reports results of efforts over a 7-year period (1960-67) to determine if the Hayes Pupil-Teacher Reaction Scale is a reliable, valid unidimensional instrument which may be used to measure the attitude of students toward the teaching effectiveness of their teachers. Criteria used were 1) each respondent's total score describes with at…

Describes the biomotometer and reports a reliability and a validity study of the instrument. (SB)

The FEM Scale, a Likert-type measure of attitudes toward feminism, was validated via data from a heterogeneous sample which indicated the FEM Scale is highly reliable, contains a single factor accounting for 38 percent total variance, and correlates with measures of anti-black prejudice, dogmatism, and indentification with the Women's Movement.…

Testing showed the dynamometer to be a sufficiently accurate instrument for recording force-time and force-displacement curves. (GW)

Describes a test, administered as a motion picture, designed to measure misconceptions about the particle model of matter held by students in grades two through six. Reliability values for tests of eight misconceptions are given and the correlations of misconception scores with measures of IQ, reading, mathematics, and science ability reported.…

A multidimensional self report measure of work attitudes of high school age youth was developed from the responses of high school students. The measure covered such topics as attitudes toward work, vocational needs and preferences, and expectations about working. A normative administration showed that the scales were reliable and independent.…

Describes the Galileo system of measurement operations including reliability and validity data. Illustrations of some of the relations between Galileo measures and traditional procedures are provided. (MH)
