This paper provides a guide to the minimum size of treatment groups, inferred from the relationships between pupil norms and norms for class averages of standardized achievement tests. (Editor)

This paper presents a number of inferential statistical models that may aid the operant investigator in presenting his data. (Author/RK)

This document describes an educational experiment designed to test the proposition that language learning can best be carried on through a program of maximum exposure in the least possible time. An experimental class of 19 average students participated in an eight-week intensive course consisting of four half-hour laboratory sessions; there were…

A diagnostic test in English as a second language should be a series of miniature tests on specific problems. Subscores in each area should be considered rather than a total score. The results should be used to probe mastery in an area rather than provide the means for comparing one student against another. The statistical reliability of the…

This paper reports on an experiment designed to investigate the effect of structural and linguistic variables on level of difficulty in solving arithmetic word problems. Identification of such variables is intended to assist curriculum writers in preparing exercises at a specified level of difficulty for students at various age levels. The study…

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…

This final report on the Pontiac Bilingual Program begins with a description of the program and a discussion of the school-community relationship established in the program. Monolingual children, language-interference students, and Anglo children are included in the experiment. The research procedures and tests used in the experiment are…

This report describes an experiment concerned with a possible relationship between the inability to learn basic educational skills, such as reading and writing, and the inability to organize incoming stimuli for communication purposes, in spite of adequate intellectual potential. The study had three main tasks. The first problem was to develop a…

This document discusses three educational experiments currently in progress within the Applied Language Research Center. Each of the programs concerns problems relating to teaching Spanish-speaking pupils in a public school setting. The Grade One Experimental Project is designed to determine if instruction in Spanish at the primary level (in an…

An evaluation of materials in the sequential anthropology curriculum project with regard to student learning and teacher training is presented. The project sample consisted of 2,183 students in grades 1, 2, 4, and 5. Two forms of the anthropology achievement test were administered as pretest and posttest measures to experimental and control groups…

The study reported here deals with the problem of determining what testing device can best indicate a foreign student's readiness for satisfactory performance at the college level, especially in courses requiring a good command of reading and writing skills in English. The study considers several standard proficiency tests and devises a formula…

A summary and comparison of the statistical analysis and results of the first three GUME research projects investigating foreign language teaching methods are presented in this report. The methods investigated are the habit-formation or implicit theory and the cognitive-code learning or explicit theory with either source-language or…

This study investigates which teaching style-Chinese bilingual or English as a second language--leads to greater oral English maturity and how useful the Chinese language is in helping a non-English-speaking Chinese person learn oral English. In the English-as-a-second-language method, the student's native language is used sparingly to avoid…

The purpose of this study was to improve the English competence of Spanish-speaking students, to increase their success in school, and to help them develop stronger self-concepts. Control and experimental groups of students were selected from kindergarten, second, and fourth grades of elementary schools with a predominantly Chicano population.…
