Studies using fear-conditioning paradigms have found that anxiety patients are more conditionable than individuals without these disorders, but these effects have been demonstrated inconsistently. It is unclear whether these findings have etiological significance or whether enhanced conditionability is linked only to certain anxiety…

This article reports on a research effort that investigated whether the use of Microcomputer-Based Labs (MBLs), implemented within an inquiry-based activity sequence on phase transformations (melting and freezing), contributes to the development of fourth grade (9-10 year-old) students' conceptual understanding and ability to construct and…

The Hawthorne and placebo effects in educational experiments were examined over a 20-year period, as reported in the ERIC, Dissertation Abstracts International, and Psych Info data bases. The literature searches identified 325 studies in education employing the relevant control procedures, and each study was coded for the type of placebo…

Selectivity bias arises in program evaluation when the treatment or control status of the subjects is related to unmeasured characteristics that themselves are related to the program outcome under study. This situation has the potential to lead to an incorrect estimation of the treatment effect when assignment to treatment and control groups is…

THIS STUDY ASSESSES THE EFFECTS OF ORTHOKINETIC SEGMENTS UPON THE MOTOR RESPONSES OF NORMAL MALE COLLEGE STUDENTS PERFORMING THE VERTICAL JUMP AND THE STANDING BROAD JUMP. THE VARIOUS PLACINGS OF THE ELASTIC AND INELASTIC FIELDS OF THE SEGMENTS UPON THE AGONIST AND ANTAGONIST THIGH MUSCLES OF STUDENTS WERE NOTED AND COMPARED WITH PERFORMANCE…

THIS STUDY WAS AN EXPERIMENTAL INVESTIGATION OF THE EFFECTS OF AN ENRICHMENT PROGRAM ON A SELECTED GROUP OF FIRST GRADERS. ITS PURPOSE WAS TO DETERMINE WHETHER CHILDREN EXPERIENCING THE EXPERIMENTAL CONDITIONS SHOWED GREATER GROWTH IN INTELLIGENCE AND ACHIEVEMENT AND GREATER USE OF FUNCTIONAL LANGUAGE THAN A CONTROL GROUP AT THE END OF ONE SCHOOL…

PROCEDURES USED IN THE 2D YEAR TO SELECT FELLOWS IN ACADEMIC ADMINISTRATION FOR A PROGRAM INITIATED BY THE AMERICAN COUNCIL ON EDUCATION WERE SIMILAR TO THOSE USED IN THE PROGRAM'S 1ST YEAR. THE PROCEDURES FOLLOWED THIS SEQUENCE--(1) PRESIDENTS OF MEMBER INSTITUTIONS NOMINATED PERSONS OF OUTSTANDING ADMINISTRATIVE PROMISE, (2) EACH INTERESTED…

Listening, the most efficient means of learning in the early grades, is replaced by reading as an efficient method for learning after the seventh grade. For an investigation of the effectiveness with which college students may be taught listening, lesson plans were developed from a programed instruction book --Principles of Selective Listening--…

One method for teaching young people how to interpret literature was defined, and the effects of that method on the responses of ninth grade students to selected short stories were measured. Four English teachers and their 94 students were randomly assigned to two experimental and two control classes. Eight short stories were read during three and…

The Dunnett procedure for comparing several treatment means with a control is applied to the problem of comparing several treatment variances with the variance of a control. Appropriate critical values are specified and an example is provided. (Author)

Designed to study implosive therapy with groups, this use of a behavioristic technique, which reduces unadaptive anxiety by emphasizing the presentation of the highly anxiety-evoking stimulus until the stimulus is no longer able to evoke anxiety, failed to produce a significant difference between control and therapy groups.
