The method of scoring is used to obtain maximum likelihood estimates of the parameters in White and Clark's (EJ 075 122) learning hierarchy validation model. From the proportion of the population possessing only the superordinate skill in a pair of hierarchical skills, and its variance, the hypothesis of inclusion is tested. (Author/CTM)

Ability to follow imperatives with one to five separate directives was measured in 18 retarded (mean IQ 50) and 18 nonretarded adolescents. Recorded were the number and sequence of directions correctly followed as well as the types of errors made. The retarded adolescent demonstrated deficiencies in following two, three, and four directives, while…

Consistent with earlier research using the Wechsler Intelligence Scale for Children (WISC) and the WISC-Revised, the Information, Digit Span, and Digit Symbol (i.e., Coding) subtests contribute substantially and independently to group differentiation. A. Bannatyne's Sequential factor also discriminates between these groups. (Author)

Provided is an analysis of Turtle Geometry using van Hiele levels of development and understanding. The author also relates a language use framework, suggested by the work of Fry (1982), to the language activities of Turtle Geometry. Research supporting the analysis is discussed. (RH)

This study investigates the effects of content sequence on student learning. The treatments, a spatial and conceptual instructional sequence each consisting of identical content elements, were administered to students in a two-year college Botany course. Hypotheses tested were that sequence would have an effect on student perceptions of the…

As the first volume of a 4-volume report evaluating the University of Massachusetts Non-Formal Education Project (UMass NFEP) in rural Ecuador, this volume presents summary responses to the following evaluation questions: (1) What does UMass NFEP purport to do? (2) How does UMass NFEP go about implementing its goals? (3) To what extent is UMass…

As the third volume in a 4-volume evaluation report on the University of Massachusetts Non-Formal Education Project (UMass NFEP) initiated in rural Ecuador in 1973, this volume presents an in-depth analysis of the evaluation findings. Since UMass NFEP was initiated for purposes of developing new materials and methodologies in conjunction with and…

Sixty-four high school students, stratified by field-dependent or independent cognitive style, were randomly assigned to homogeneous or heterogeneous groups of four to attain concepts in the sequence of complex to simple or simple to complex, with either minimal or strategy instructions. Subsequently, each student individually attained four…
