A theory-driven approach to evaluation (TDE) emphasizes the development and empirical testing of conceptual models to understand the processes and mechanisms through which programs achieve their intended goals. However, most reported applications of TDE are limited to large-scale experimental/quasi-experimental program evaluation designs. Very few…

The major purpose of this paper is to examine the problems of geralizing from the Graduated Work Incentive experimental setting to the national labor-supply responses that would be generated by a negative income tax that replaced existing welfare programs for families headed by able-bodied males. (Author/BP)

Among the many problems in interpreting the results of the experiment is the determination of what can be inferred from a limited duration experiment about the behavioral effects of a negative income tax. This paper examines and interprets experimental data based on the labor supply model. (Author/BP)

This document reports on research aimed at establishing effective methods for training Navy marginal personnel designated as Group 4. Preliminary investigation of training in mathematics showed that Group 4 personnel needed to improve in basic arithmetic skills and that they varied widely in their ability to acquire such skills. An experimental…

A STUDY WAS CONDUCTED TO COMPARE THE EFFECTIVENESS OF TWO KINDS OF CONFIRMATION IN PROGRAMED INSTRUCTION--RESPONSE CONFIRMATION AND EXAMINATION FEEDBACK. EXPERIMENTAL CONDITIONS OF HIGH, MEDIUM, AND LOW STUDENT MOTIVATION AND HIGH AND LOW ERROR-RATE WERE UTILIZED. RESPONSE CONFIRMATION REFERS TO THE CONVENTIONAL METHOD OF CONFIRMING EACH ONE OF…

Project Broad Jump is a New York-based education program for some 600 youngsters from urban areas, in the third through tenth grades. The basic concept of the program is that academic opportunities are not accessible to many inner-city youth, whereas Head Start and Follow Through help pre-third graders, and Upward Bound helps high school students.…

The article offers a brief history of past income-maintenance programs summarizes a unique income-maintenance experiment, describes present welfare programs, and lists the unanswered questions in welfare reform. (Income maintenance for intact families at levels employed in the study would not have large effects on labor supply, concluded…

The authors describe the general conceptualization of personalized instruction that has evolved with the program and suggest some implications for future investigations of the impact of such a personalized program. (Author)

The purpose of this project was to relate mathematics studies to the students' natural enthusiasm for popular music and favorite performers. Learning modules rather than lesson plans were used as the teaching approach in the experimental music-mathematics classes. Stated objectives of the project were (1) to motivate students to learn to code and…

Project Success Environment is an experimental program sponsored by the Atlanta Public Schools and funded by the State Department of Education under Title III of the Elementary and Secondary Education Act of 1965. The focus of this program, subtitled "An approach to Community Educational Improvement," is the development of a success…

In 1964 the University of Minnesota initiated a three-year TV College as an experiment in offering courses to more freshmen and sophomores without compromising quality. The four courses offered in 1964 and the nine in 1965 were taught by regular University faculty and carried full resident credit. They were supplemented by weekly discussion…

In preparation for evaluation of programed spelling instruction, a grade 5 spelling program was designed, teachers were given special training, and an educational motivation scale was developed. Of the three subject groups used to carry out the investigation--(1) control, taught by the conventional method; (2) experimental, taught by programed…
