If people believe that some property is true of all members of a class such as sofas, then they should also believe that the same property is true of all members of a conjunctively defined subset of that class such as uncomfortable handmade sofas. A series of experiments demonstrated a failure to observe this constraint, leading to what is termed…

Conversational technologies such as email, chat rooms, and blogs have made the transition from novel communication technologies to powerful tools for learning. Currently virtual worlds are undergoing the same transition. We argue that the next wave of innovation is at the level of the computer interface, and that mixed-reality environments offer…

This study investigates the efficacy of symbolic modeling and role-playing therapy in the reduction of avoidance behaviors. After treatment, role-playing subjects demonstrated significantly less avoidance behavior and lower subjective fear ratings than the modeling or control group subjects. (Author/SJL)

Describes a study designed to challenge the theory that the initial phase of instruction in foreign language should be based on intensive oral practice. (PMP)

The present study was carried out to evaluate the effects of two different but related treatments (feedback and self charting) which are often found in behavioral reading programs but which are usually not a formal part of other tutoring methods. (Author/RK)

Describes an experiment in which the learning contract method was used in a philosophical ethics course and assesses the learning contract method as compared to the discussion method. (Author/PG)

This research investigates stochastic approximation procedures of the Robbins-Monro type. Following a brief introduction to sequential experimentation, attention is focused on formal methods for selecting successive values of a single independent variable. Empirical results obtained through computer simulation are used to compare several formal…

An experiment that proved worthwhile at Lehman College is reported, in which student teams learned how and produced research papers, a requirement in half the courses on the campus. (Editor/PG)

Innovation is difficult to define because a practice which is innovative on one campus may not be innovative elsewhere. Nevertheless, a possible definition might be "a practice which is worthy of emulation and has not yet been put into use by a significant number of colleges." Administrators should seek instructional innovation for several…

THE PURPOSE OF THIS STUDY WAS TO COMPARE TWO TEACHING METHODS FOR DEVELOPING PRODUCTION TYPEWRITING ABILITY. THE TRADITIONAL, SPEED-EMPHASIS METHOD AND THE EXPERIMENTAL, PRODUCTION-EMPHASIS METHOD, WERE USED DURING 50-MINUTE PERIODS FOR 61 SESSIONS EACH SEMESTER WITH STUDENTS ENROLLED IN INTERMEDIATE TYPEWRITING AT INDIANA UNIVERSITY DURING…

THE MANY ACTIVITIES RESULTING FROM THE RECENT EMPHASIS UPON IMPROVING EDUCATION SHOULD CONCERN THE MAJOR PROBLEMS, RESEARCH TOPICS, AND PRIORITIES IDENTIFIED THROUGH A SUGGESTED SYSTEM OF VOCATIONAL EDUCATION BOOKKEEPING IN WHICH RESULTS ARE REVIEWED BY APPROPRIATE STAFF AND RESOURCE PERSONNEL FROM BUSINESS, INDUSTRY, COLLEGES, AND UNIVERSITIES.…

The purpose of the study was to explore the extent to which a prototype multi-media self-instructional system comprised of 48 lessons can be used to help grade 11 and 12 students acquire defined levels of Gregg shorthand capabilities. Criteria for measuring student competencies and performance objectives at interim points and at the completion of…

This report of the Teacher Aide Program in the Minneapolis, Minn., Public Schools, funded under Title I of the Elementary and Secondary Education Act, is divided into four sections. The first section is "An Overview of the Evaluation of the Teacher Aide Program, Academic Year, 1966-67." The next two sections summarize questionnaire…

This article addresses the question, "Does the introduction of a language laboratory improve the functioning of a given teaching method?" Four experiments with the language laboratory are described and analyzed: the Keating and Lorge experiments in New York, the Jalling experiment in Sweden, and the Freedman experiment in Great Britain. These…
