To help the PLATO computer-based instruction system user achieve the most efficient storage and manipulation of data, this manual begins with a review of the structure of decimal, binary, and octal number systems, and methods for converting from one system to another. The text describes the four basic operations that PLATO employs to manipulate…

The work reported here was performed between 1 June 1967 and 31 May 1968 under Task I of the contract between Chemical Abstracts Service (CAS) and the National Science Foundation (NSF). The objective of this contract was to achieve an operational, integrated, man-machine system for manipulating information about chemical substances. The contract…

The paper descibes a compact and highly efficient disk file management system responsible for the management and allocation of space on moving head disk drives in a medium-scale time-sharing system. The disk file management system is a major component of the Experimental Time-Sharing System (ETSS) developed at the Learning Research and Development…

This paper describes the efforts of the Program on Teacher Effectiveness of the Stanford Center for Research and Development in Teaching to survey and catalog available teacher training products. It is stated that the project developed from the program's own need to identify potential products which could be incorporated into the program's…
