We present a set-theoretic model of the mental representation of classically quantified sentences (All P are Q, Some P are Q, Some P are not Q, and No P are Q). We take inclusion, exclusion, and their negations to be primitive concepts. We show that although these sentences are known to have a diagrammatic expression (in the form of the Gergonne…

TO ELIMINATE THE PROBLEMS ARISING FROM THE ACQUISITION OF INAPPROPRIATE MEDIA MATERIALS AND EQUIPMENT, AN INSTRUCTIONAL SYSTEMS UNIT WAS DESIGNED, TESTED AND EVALUATED AT OHIO STATE UNIVERSITY SCHOOL OF EDUCATION. THE SYSTEM, DEVISED WITH THE AID OF A REVIEW OF THE APPROPRIATE LITERATURE, CONSISTS OF FIVE PHASES--(1) IDENTIFYING THE PROBLEM AND…

MODELS OF A SCHOOL COUNSELOR'S COGNITIVE BEHAVIOR IN THE APPRAISAL OF STUDENT INFORMATION AND OF HIS OVERT VERBAL RESPONSES IN THE "EDUCATIONAL PLANNING INTERVIEW" WERE MADE WITH COMPUTER PROGRAMS AND COMPUTER-CONTROLLED EQUIPMENT. THE VERBALIZATIONS OF THE COUNSELOR WHILE REVIEWING THE RECORDS OF 20 NINTH-GRADE STUDENTS PRIOR TO…

Documenting treatment integrity is an important issue in research and practice in any discipline concerned with prevention and intervention. However, consensus concerning the dimensions of treatment integrity and how they should be measured has yet to emerge. Advances from three areas in which significant treatment integrity work has taken…

This basic aim of this paper is to explore and describe how the results of experimentation are transmitted from the "laboratory" campus to other campuses and to propose ways of improving and expanding the dissemination process. Chapters cover: (1) New College as a model, (2) "new" elements in New College's program, (3) the…

The report outlines the administrative setting and describes the experimental design to be used in field testing the Mark II model of the Automated Pronunciation Instructor (API) system. It presents the draft instructional curriculum for the Spanish-English and the English-Mandarin Chinese language pairs, and describes the hardware, pedagogical…

Because it included only public schools and guaranteed both school survival and staff employment rights, the first year of the Alum Rock demonstration (1972-73), as sponsored by the Office of Economic Opportunity, was not a test of vouchers as defined in theory. The demonstration was known, therefore, as a "transition" voucher model,…

The task is to carry out the final development of a computer-based system for automated instruction of the new speech sounds of second languages, and to field-test this system for two language pairs: English speakers learning Mandarin Chinese, and Spanish speakers learning English. This report describes the first evaluation experiment of the Mark…

The technique originating from the study of ecological systems for the examination of dynamic educational systems over time is utilized. The technique is based on the theory of energy exchanges in interactions between variables. Using this technique, interactions among variables can be specified and simulated over time using an analog computer.…

Part 1 of this report outlines the concept of vouchers and the nature and objectives of the New Rochelle study. The more pertinent work tasks undertaken to accomplish the objectives are contained in the appendix. The authors describe their position regarding the voucher plan, highlight its major elements, and outline the steps the district should…

The procedures used in the initial development of a Mathematics Laboratory within the Individually Prescribed Instruction (IPI) Mathematics Program are reported. The thesis of the report is that in the development of educational programs, especially those which are complex, attention should be directed both to the design of the program and the…

The problems now confronting public education in the cities represent some of the major reasons for advocating the voucher system. This report identifies many of these problems, examines the concept of educational vouchers, and raises some policy and research issues that should be considered before such a system is tried. The author outlines a…

The culmination of many years of implementing and analyzing the Bank Street model in Project Follow Through, this paper provides an extensive discussion of controversial and problematic issues related to the program and reviews what has been learned at Bank Street as a result of experience with Follow Through. Recommendations for program…

THE OBJECTIVES OF THE STUDY WERE TO COMPARE EDUCATIONAL TOYS AND THREE-DIMENSIONAL NONPRODUCING MOCKUPS WITH COMMERCIAL PLASTICS PROCESSING EQUIPMENT FOR RELATIVE EFFECTIVENESS OF TEACHING PLASTIC CONCEPTS, AND TO COMPARE THE RELATIVE EFFECTIVENESS OF THESE TWO METHODS IN DEVELOPING MANUAL DEXTERITY. TREATMENT A (EDUCATIONAL TOYS AND MOCKUPS) WAS…

An experiment was designed to compare two alternative procedures for revising a preliminary version of an instructional program, one based on a subjective analysis of the program's behavioral goals, the other on an objective analysis of test data obtained from a trial of the unrevised program. Conforming to an experimental model, 20…
