This report examines the top Third International Mathematics and Science Study-Repeat (TIMSS-R) performers and compares Delaware classroom environments with those of the top performing students. Data analyses show that Delaware's average class size is larger than any of the top performers, and student attendance, skipping, and tardiness problems…

Multiple discrimination problems were presented concurrently to retarded children for 1, 2, 4, or 8 massed trials a day for a total of 16 trials per problem. (Editor)

This article attempts to estimate the most successful method for measuring effective teaching. (RK)

Reports a study of the impact of teacher race on the performance of inner city high school students on a listening comprehension test. (JM)

To reduce confusion regarding reported effects of age on maximal exercise heart rate, a comprehensive review of the relevant English literature was conducted. Data on maximal heart rate after exercising with a bicycle, a treadmill, and after swimming were analyzed with regard to physical fitness and to age, sex, and racial differences. (Authors/PP)

This study investigated whether a pattern for the development of motor ability could be discerned, using the same range of motor performance tests with boys and girls at 10 different age levels. Researchers did not find a pattern as clear as has emerged in personality and intelligence development. (PP)

Examines several possible difficulties in interpreting the results of studies which employ Piagetian tasks, especially conservation tasks, with older individuals. Notes that Piaget's clinical method allows more flexibility in the assessment of competence than do more quantifiable techniques. Examines the possibility of task misinterpretation by…

Briefly reviews different methods to evaluate student laboratory work and describes the procedures followed in using laboratory performance tests at Mercer University. Cites five sample performance-test tasks and materials needed. (SK)

A Wherry-Wherry hierarchical factor solution was obtained on the Wechsler Adult Intelligence Scale (WAIS) subtest performance of 100 adolescent retardates. The hierarchical arrangement of abilities obtained was consistent with Vernon's model of cognitive structure and previous reports. A g-factor and two major group factors were evident.…

Examined whether a significant difference exists between variable of ethnicity and scores attained on a minimum competency test using high school juniors as subjects (N=2,681). Found ethnicity influenced competency scores; reading scores were influenced by sex; and ethnicity and sex negatively affected whether student passed or failed competency…

Discussion of testing methods that adequately measure the ability to perform manipulative tasks focuses on criterion-referenced performance tests (CRPT) to evaluate trainees. Topics discussed include predictive validity; physical fidelity; test construction; testing constraints; performance conditions; criteria for attainment standards; scoring…

Sixty-five persons with visual impairments were videotaped as they located and learned the arrangement of five objects in a novel space. Analysis of videotapes and verbal self-reports of the 15 best performing participants revealed that they implemented systematic perimeter and/or gridline patterns, utilized their canes efficiently, and…

A model integrating latent trait and latent class theories in characterizing individual performance on the basis of qualitative understanding is presented. This HYBRID model is illustrated through experiments with 119 Air Force technicians taking a paper-and-pencil test and 136 Air Force technicians taking a computerized test. (SLD)

Elementary performance tests and situational or simulation tests may be combined for comprehensive testing of open skills, i.e., a worker's competency in reacting to unpredictable situations. Elementary performance tests capture the professional skills whereas simulation tests retain realism and complexity and allow variation in responses.…
