Clarifies the terminology involving the terms "Laboratory Technician,""Laboratory Assistant," and "Laboratory Steward" and describes the effective use of the science technician. Groups the various tasks of the technician and enumerates the duties involved in each group. (GS)

Two experiments used the sentence-picture verification paradigm to study encoding and comparison processes with spatial information. Subjects decided whether a spatial description of a geometric figure matched a second figure. Three critical results demonstrated that task-specific variables could be the primary determinants of how subjects verify…

Presents specific ideas on designing, planning, and staffing a training facility for industrial technicians. Facilities should be designed in relation to curriculum, traffic control, and safety. Trainer success is often based on both skills and attitudes. Presents case study at Commonwealth Edison; also reviews process by which various maintenance…

Tree searching was applied as a computer model of simple addition sentences. Results indicated that the number of problem reductions performed in tree searching accounted for most of the variance across problems in student error rate and solution time. The technique constitutes a computer test for the adequacy of a problem solving prescription.…

A properly chosen test model defines the kind of dependence of the observable behavior on underlying abilities of the persons tested in the form of a data-adequate theory. The limitations and potential of several test models are detailed; and they are critically compared as an aspect of empirical evaluation. (Author/MV)

The verbal analogy item as a measure of intelligence is investigated. Using latent partition analysis, this study attempts to identify a semantic structure of relationships that individuals use to comprehend completed analogies. The implications for test construction and test validity are discussed. (Author/JKS)

Two home economists take a dim view of task sharing as the way out for the employed homemaker. What is needed, the authors say, are educational programs in time management. Specifically, they suggest noon workshops--with the employer's blessings. (Editor/HD)

The recordkeeping-accounting competencies in business education curriculums should be those needed by all prospective office workers, not just bookkeepers. A task inventory booklet (developed by the Vocational Technical Education Consortium of States) completed by incumbent office workers showed that some of the recordkeeping-accounting tasks…

Presents a study of inferential problem solving abilities of 5-year-old children. Tasks involved the combination of separately acquired behavior segments in order to solve a novel problem. (BD)

Preschool children between 3 and 5 1/2 years of age participated in a learning task in which a conditional relational problem was presented in either a blocked or random series. Prior training on the components of the task was also varied. (BD)

A developmental reversal in accuracy was obtained for third and sixth graders and adults who judged class membership of patterns presented in a same-different task. Reversal accuracy appeared to result from an increase with age in orientation-free judgments. This hypothesis was confirmed in the subsequent two experiments. (GO)

Noun pairs were learned by younger and older adults. Anticipation and presentation intervals were manipulated, and there were no-imagery, experimenter-provided imagery, and self-generated imagery instructions. Older subjects generated and used imagery with the same facility as younger subjects, although retrieval time was longer. (GO)

Investigated the development and fragmentation of categories over chronological and mental age without the requisite of free recall. Kindergarten, fourth grade, ninth grade and retarded students labeled and categorized chromatic slides of picturable objects. (GO)

The rule space model permits measurement of cognitive skill acquisition and error diagnosis. Further discussion introduces Bayesian hypothesis testing and bug distribution. An illustration involves an artificial intelligence approach to testing fractions and arithmetic. (Author/GDC)

Task performance measures are criterion-referenced tests that can improve the effectiveness, accountability, and control of vocational training programs. They provide the means for basing instruction and evaluation on job performance requirements rather than arbitrarily derived subject matter. (JOW)
