Procedures for implementing random assignment with trickle processing and ways they can be corrupted are described. A computerized method for implementing random assignment with trickle processing is presented as a desirable alternative in many situations and a way of protecting against threats to assignment validity. (SLD)

The goals of the Digital Systems Education Project (DISE) include the development and distribution of educational/instructional materials in the digital systems area. Toward that end, this document contains three reports: (1) A FORTRAN IV Design Program for Low-Pass Butterworth and Chebychev Digital Filters; (2) A FORTRAN IV Design Program for…

This final report describes the development and test of a computer readability editing system for use in improving the ease of comprehending Navy technical manuals and training materials. The prototype editing system has features to (1) flag uncommon and misspelled words and long sentences, (2) suggest simple replacements for difficult words, and…

Offers a critique on some of the papers on computers in science teaching that were presented at the 1985 National Association for Research in Science Teaching meeting. Implications for the conduct of research on computers in science learning are also suggested. (JN)

The substance of a commentary (SE 539 500) is a criticism of the over-generalizations by authors of computer-assisted instruction papers at the 1985 annual meeting of the National Association for Research in Science Teaching. This reaction attempts to examine the validity of the criticisms made in the commentary. (JN)

A series of six functions and a station command have been designed to enable Coursewriter II authors to use the plotting capability of the IBM instructional system in presenting course material. This capability has been augmented to include the ability to graph mathematical functions or other data on the 1510 terminal. Documentation of the Plot…

This paper discusses the incorporation of heuristics in computerized decision aids that are used for structuring decision problems. Decision theory is described in terms of linked subsystems, and sites where it is necessary to employ heuristic rather than normative, algorithmic procedures are identified. Production systems are then used to…

Designed to aid in the orientation of personnel newly assigned to the Office of Manpower Utilization (OMU), Marine Corps Headquarters, this manual provides a brief overview of Marine Corps Task Analysis (TA) by presenting the basic steps in this process, which are (1) construct a task inventory, (2) administer self-report inventory, (3) analyze,…

The Navy has long been aware of a literacy gap existing between the level at which Navy technical documents are written and the reading comprehension level of enlisted personnel. In order to provide guidance in the restructuring of text and the limiting of vocabulary to reduce this gap, the Training Analysis and Evaluation Group developed the…

A computer-assisted analysis of studies on referential communication (giving directions/explanations) located 66 reports involving 80 experiments, 114 referential tasks, and over 6,200 individuals. The studies were entered into a statistical software package system (SPSS) and analyzed for characteristics of the subjects and experimental designs,…

A procedural variable, the use of computers to score the students' assignments, is being studied as it affects performance on correspondence courses. The format used is known as CALS-Computer Assisted Lesson Service. Courses were converted to an objective type lesson format which the student responded to using an electronically read answer sheet.…

Investigated were the effects of programing instruction with BASIC on mathematical thinking skills and concept development in grade six. Posttests assessed programing ability, generalization, and understanding of variables. Observations and interviews were also used. The groups having programing instruction scored significantly higher than the…

A university-wide project team of academic and administrative staff worked together to prepare, deliver and evaluate a number of diagnostic, formative and summative computer-based assessments. The team also attempted to assess the University of Southampton's readiness to deliver computer-assisted assessment (CAA) within the "Code of practice…

Because there is little theoretical background to explain the process of adopting computers for instruction in postsecondary institutions, this paper reviews the literature on this process from the perspective of technological innovation. Technological innovation is defined as the use of tools and techniques which extend human capability and which…

Describes use of selective dissemination of information (SDI) feature on DIALOG at Sandia Technical Library to produce bulletin announcing library acquisitions of technical reports in microfiche. Microfiche acquisition, developing profile, assembling profile output, costs, and suggestions for improvement are highlighted. Examples of SDI profiles…
