Three subsidiary issues are discussed that raise further questions about the generality of conclusions regarding the effects of massed and distributed practice on the learning of motor skills: (1) duration of practice; (2) learning-performance distinction; and (3) data synthesis and theory development. (JD)

A review and commentary on the previous article discusses the effects of stabilized retinal images on performance and the perceptual organization of a patterned skill. Future research on distribution-of-practice is considered. (JD)

A critique of the lead article on the effects of practice distribution on motor learning points out that while this is not a new issue, it brings up some important concerns that are not unique to the practice distribution issue but are problems in any investigation of skill learning. (JD)

Criticism of the theory that massed practice depresses performance as well as learning asserts that any generalization based on some limited amount of admissible evidence will provide an incomplete description of the psychological processes underlying skill learning. (JD)

Further commentary on distributed practice and the acquisition of motor skills points out that there are at least two viable theoretical perspectives that can be brought to bear on issues surrounding the acquisition of perceptual-motor skills. (JD)

This document provides a composite index of the first five sets of software annotations produced by Project SEED. The software has been indexed by title, subject area, and grade level, and it covers sets of annotations distributed in September 1986, April 1987, September 1987, November 1987, and February 1988. The date column in the index…

Provides information and reviews of geography computer software classified as drill-and-practice, simulations, and databases. Includes title, publisher, hardware needed, suggested grade level, geographic area covered, content emphasized, and the strengths and weaknesses of each program. (TW)

Presents reviews of six software packages. Includes (1) "Plain Vanilla Statistics"; (2) "MathCAD 2.0"; (3) "GrFx"; (4) "Trigonometry"; (5) "Algebra II"; (6) "Algebra Drill and Practice I, II, and III." (PK)

Reviews two software packages; "Block It, An Instructional Game" and "Conquering Whole Numbers." The first is a simulation game which uses graphic representation of base-ten blocks to reinforce place value and regrouping. The second package is designed to give students in grades three through six practice in computation. (PK)

Describes two software programs for the Apple II series and TRS-80 Models III and IV: (1) "Personal Energy Inventory" (grades 9-12, records and manages data, not considered user friendly); (2) "Energy Conservation" (grades 7-12, aids in converting and problem solving, uses drill and practice). (MVL)

Presents five computer programs: (1) Accurate Numerical Solutions of the One-Dimensional Schrodinger Equation; (2) NMR Simulation and Interactive Drill/Interpretation; (3) A Simple Computer Program for the Calculation of 13C-NMR Chemical Shifts; (4) Constants of 1:1 Complexes from NMR or Spectrophotometric Measurements; and (5) Saturation…

Provides a list of evaluation services currently producing critical reviews of educational software. Includes information about The Apple K-12 Curriculum Software Reference, The Educational Software Preview, The Educational Software Selector, MicroSIFT, and Only The Best: The Discriminating Guide for Preschool-Grade 12.
