This study examined the effect of scaffolding learning components in a computerized environment, for students solving qualitative science problems in a simulation of laboratory experiments. Four scaffolding components were identified (structural, reflective, subject-matter and enrichment) and used in different configurations to construct four…

Group parent-training interventions for the treatment and prevention of externalizing problems in young children have been empirically validated almost exclusively with mother-only groups or with groups where the majority of participants are mothers. One reason for this focus has been the difficulty in attracting fathers to parent-training groups.…

The purpose of this study was to compare two non-parametric procedures, the Mantel-Haenszel (MH) procedure and the simultaneous item bias (SIB) procedure, with respect to their Type I error rates and power, and to investigate the conditions under which asymptotic distributional properties of the SIB and MH were obtained. Data were simulated to…

Internship experience is a valuable component of an undergraduate degree. This is especially true in leadership education programs, where leadership development may take place in a variety of contexts. Theory purports reflection enhances a learners' experience through a linkage of education, work, and personal development (Kolb, 1984). It is not…

Outcomes of a follow-up, preventive care program based on a self-regulation model of neonate and parent behavior were studied in a controlled experiment. Subjects included a preterm control group, preterm intervention group, and full-term control group, with each group consisting of 27 infants. The assessment, which used the Brazelton Neonatal…

This study explores the use of the adjunct question paradigm in self-instruction and distance education materials. The subjects were 187 high school students who read text passages and answered one high level (implication or inference) or low level (verbatim or paraphrase) question. These questions were either inserted in the text or massed at the…

The pretest-posttest design referred to as Design 2 by Campbell and Stanley (1963) is commonly used in educational research and evaluation. The tenability of the assumption of a zero population difference commonly used with this design is questioned. A nonzero population estimate based on the mean difference observed in test-retest reliability…

The effects of a three-year Organization Development (OD) intervention on power equalization were examined in seven experimental and seven control schools. The principals and teachers from experimental schools participated in OD workshops, in a project-coordinating council for planning and policy, and in school goal-setting activities. The power…

SIGNIFICANT FACTORS INVOLVED IN LEARNING AND ADJUSTMENT OF RETARDED CHILDREN IN SPECIAL CLASSES AS COMPARED WITH THOSE REMAINING IN REGULAR CLASSROOMS WERE ASSESSED. EACH GROUP WAS EVALUATED WITH INSTRUMENTS TESTING INTELLECTUAL CAPACITY, SCHOOL ACHIEVEMENTS, SOCIAL ACCEPTABILITY, AND ADJUSTMENT TO THEIR TEACHERS AND PEER GROUPS. IT WAS FOUND THAT…

THE OBJECTIVES WERE TO DETERMINE THE EFFECT OF TEACHERS' ATTITUDES TOWARD CREATIVE THINKING ON THEIR EVALUATIVE BEHAVIOR IN THE CLASSROOM AND ON THE CREATIVE THINKING OF THEIR PUPILS. FURTHER OBJECTIVES WERE TO ASCERTAIN THE EFFECTS OF VARIOUS KINDS OF EVALUATIVE COMMENTS ON THE IDEAS OFFERED BY STUDENTS, AND TO DETERMINE WHETHER OR NOT…

THE PROJECT SOUGHT TO ESTABLISH VOCATIONAL ASSESSMENT PROCEDURES, PROVIDE A WORK CONDITIONING PROGRAM TO INCREASE WORK POTENTIAL, AND PROVIDE AFTERCARE SERVICE AND FOLLOWUP. THE MAJOR HYPOTHESIS WAS THAT PATIENTS GIVEN A PROGRAM OF WORK CONDITIONING WERE MORE LIKELY TO BE PLACED IN WORK SITUATIONS IN THE COMMUNITY AND TO REMAIN LONGER OUTSIDE THE…

An interim evaluation was conducted to determine the impact of the National Supported Work Demonstration (NSWD) on employment of four target groups: Aid for Dependent Children (AFDC) recipients, ex-drug-addicts, ex-offenders, and youths. The evaluation was based on data collected in interviews with 2,830 persons--1,419 of whom were offered…

A 7-year study is being conducted to determine if an 8-month intellective training program at ages two and three will improve a child's performance and if the effects will last through the first grade. The subjects consist of 240 Negro males from all social levels in Manhattan. Half of them are 2 years old and half are 3 years old. Subjects were…

A study was made to see if an educational program on the safe and proper use of pesticides would increase the opinion leadership activities of pesticide dealers and the amount of quality of information they conveyed to their customers and other dealers. The dealers selected came from eight rural counties and two urban communities in Nebraska; they…
