An instrument was developed to measure students' perceptions of twelve specific features in the learning environment for science instruction in institutions concerned with preservice elementary teacher education. The instrument appears to be promising for the investigation of individual differences in perception and differences in learning…

The purpose of this research was to further study the breadth and depth dimensions of the WAIS similarities and vocabulary subscales by factor analyzing several measures of intelligence: a comprehension index, SAT scores, and grade point average (GPA). (Author/SJL)

The development and validation of the Vocational Interest Inventory, a forced choice guidance instrument is described. It assists high school students, whose interests are not well differentiated, in making post-high school educational and vocational decisions. (JKS)

Using critical incidents, faculty ratings of graduate student performance in departments of chemistry, English, and psychology were collected. Separate factor analyses in each field produced eight fairly consistent factors with respect to item loadings across fields. Faculty ratings of each incident with respect to its importance for success were…

The structure of "teacher efficacy" was studied with a sample of 342 prospective and experienced teachers through an efficacy questionnaire. Factors correspond to an internal versus external distinction, similar to the locus-of-control measures of causal attribution. (SLD)

The development of the new fifth edition of the Sixteen Personality Factor Questionnaire (16PF) is described. The factor structure of the new 16PF was explored with 4 samples ranging from 646 to 3,498 subjects. Results support the validity of the 16PF factor structure and its continuity with earlier versions. (SLD)

The construct validity of a supplemental scoring system for the Kaufman Assessment Battery for Children (K-ABC) was evaluated with 146 referred school-age children (aged 6 to 12.5 years) and the K-ABC normative sample. Results support the construct validity of only part of the scoring model. (SLD)

Investigated the factor structure of a battery of tasks hypothesized to measure the constructs of the planning, attention, and simultaneous-successive (PASS) process model of human cognition. Results suggest that the original PASS model provides an improper factor solution. Recommends further refinement of the PASS theory or tests. (RJM)

This study examined the construct validity of the KeyMath-Revised by testing the factorial model proposed by the test author. Results failed to confirm the proposed factorial model and suggested that the KeyMath-Revised assesses two domains that are difficult to interpret, rather than the three proposed by the test author. (Author/JDD)

Scores on ability tests given to 1,274 students in grades 4-6 and 1,310 in grades 7-9 were simultaneously factor analyzed at class and individual levels. At the individual level, the general factor was most highly loaded on fluid abilities. Three common factors were established at the class level. (SLD)

A Monte Carlo investigation of simplex fitting as a method of determining the dimensionality of binary data matrices was conducted. Examination of the fit of correlation matrices with a known factor structure to correlation matrices that represent the perfect simplex shows that simplex fitting is a feasible approach under some circumstances. (SLD)

Analysis of Kaufman Assessment Battery for Children (K-ABC) Sequential and Simultaneous Processing scores of 94 children (ages 6-12) with learning disabilities produced factor patterns generally supportive of the traditional K-ABC Mental Processing structure with the exception of Spatial Memory. The sample exhibited relative processing strengths…

Examined factor structure of the emotional Autonomy Scale (EAS) in 3 samples of adolescents, with each sample consisting of 3 racial/ethnic groups. Found that the EAS exhibited poor construct validity and behaved quite differently for different grade and ethnic groups. Suggested that the most credible solution may be to reexamine the conceptual…

The stability of a 2-factor model proposed for the Gibb Experimental Test of Testwiseness was studied with 173 undergraduates. Confirmatory factor analysis results indicate that data fit the two-factor model and a simpler one-factor model. The Gibb test could be characterized as tapping a general testwiseness proficiency. (SLD)

The structure of temperament over the ages 3 to 7 years was investigated through factor analysis of maternal ratings of 1,366 children on the Childhood Temperament Questionnaire (CTQ). Found four strong factors (inflexibility, sociability, persistence, and rhythmicity) and two weak ones (activity-mood and threshold). Discusses the strengths and…
