The Boehm Test of Basic Concepts Revised was developed to measure the understanding of basic positional concepts of young children whether individuals in kindergarten, 1st grade and 2nd grade can correctly identify a picture from among a choice of three when presented with verbal cues incorporating such terms as over, least, left and so on. Based on these results children can be identified as deficient in conceptual development with resultant curricular implications. Scoring: Once scored, the results can be translated into percentiles which may be done by socioeconomic level or by the total group. Reliability: A number of measures of the reliability of the instrument are presented. Correlations reported between Forms C and D (N=625) are 0.82 for Kindergarten, 0.77 for 1st grade and 0.65 for 2nd grade. Correlations of Forms C and D with Form A of the Boehm Test of Basic Concepts (N =173) are 0.65 and 0.62 respectively. Split half reliability coefficients and standard errors of measurement are presented by form, grade and socioeconomic level. These relationships vary between 0.55 and 0.87 with the coefficients being lower at 2nd grade than at Kindergarten and 1st grade. |
Validity: Validity is measured through the relationship of scores on the Boehm Test of Basic Concepts-R and various measures of academic achievement (the total batteries of the Comprehensive Test of Basic Skills , the California Achievement Test, and the Iowa Test of Basic Skills) as well as through reading level as measured on the Harcourt Brace Jovanovich Book mark Reading Program. The coefficients of correlation varied from 0.24 (Grade 2 applications with ITBS) through 0.64 (Kindergarten Form D with CTBS), with a median of 0.44.
Norms: The norming of the Boehm-R occurred in 1983, involving approximately 10,000 children in public school districts selected as nationally representative by size of the district and geographic location. Socioeconomic status was estimated based on each building's percentage of students who qualified for subsidized lunches, not on the characteristics of the individual children.
Suggested Uses: Recommended for assessment of receptive conceptual development in educational and research settings.
Purpose:The Boehm Test of Basic Concepts is designed to measure the basic positional concepts of young children.
Population: Kindergarten through second grade.
Score: Percentile or Total Group scores.
