This study explores the relationships between a child's discriminatory abilities in the areas of pitch, intensity, rhythm, timbre, and tonal memory and his capacity to comprehend and speak the Spanish language. The Spanish accent is analyzed on the basis of intonation, stress, sinalepha, and phone production. These factors were tested both in…

This report summarizes the results of a 3-month feasibility study of the education voucher plan for the City of Seattle. This study represents the activities conducted as the Phase I portion of the 4-phase voucher plan (February 15-May 15, 1971). The first section focuses on activities in the State of Washington relevant to the inception of the…

The goal for the second year of the Colorado Mexican-American Student Program was to motivate and inspire a selected number of high school students to seek a college education. Students for the program were selected according to 5 criteria: (1) Mexican American ancestry, (2) promising academic potential, (3) completion of grade 10, (4) average or…

This report represents an integration of analysis results in an interim report with those from additional analyses performed since. It is divided into (1) description of the experiment in which the goal is outlined; (2) description of the technology company programs, an overview of personnel, curriculum and materials, and incentive systems; (3)…

This report summarizes the principal findings for the O.E.O. experiment in performance contracting. The report emphasizes major results and conclusions to date. It is divided into (1) description of the experiment, in which the goal is outlined; (2) description of the technology company programs, curriculum and materials, and overviews of…

There is a need for empirical investigation of the optimal length for drill sentences at various states of second language learning. This paper reports the results of a study that explores the effects of sentence length and grammatical structure on the ability of foreign students to repeat English sentences. It was hypothesized that sentences of…

The Conference sought to provide a user-based and -oriented assessment of performance contracting for education. It focused on delineating the current interest in performance contracting, the technique's demonstrated strengths and weaknesses, and its potential as an alternative approach to school system resource allocation. Six commissioned papers…

The teaching of dialect modification has been justified by the barrier postulate which says that lower class speech prevents upward social mobility. When translated into a testable hypothesis, the barrier assumption has not been confirmed. The movement called dialect modification did not arise from empirical research in social cognition, but…

This document discusses in detail the development and operation of a language program implemented in the Philippines, beginning in 1957, with the assistance of the University of California, Los Angeles, through the Rockefeller Foundation. The program faced a number of difficulties including a school system in the process of post-war rebuilding, a…

As a part of a doctoral thesis considering the history of teaching physical and chemical change, 641 chemistry/science textbooks have currently been examined. These books are from many different countries and date from the eighteenth century to the present time. The books have described a wide variety of experiments to illustrate the difference…

Science projects are a great way for students to learn more about science as they search for the answers to specific problems. This book offers guidance and provides ideas for students as they plan experiments, find and record information related to the problem, and organize data to find answers to the problem. The 20 topics in this book suggest…
