Until 1975 around half of all graduates from Dutch basic vocational schools finished a 3-year program, the other half finished a 4-year program. In 1975 all 3-year programs were extended to four years. This was accompanied by an increase of the compulsory school leaving age with one year. The authors evaluate the long-term wage effects of this…

The speech and language developmental progress of children with hearing loss educated using an Auditory-Verbal approach was compared to that of a control group of children with normal hearing. The experimental group consisted of 29 children ages 2-6 years with a mean pure tone average in the better ear of 76.17 dB HL at 0.5, 1 and 2 kHz. The 29…

An experiment in problem-solving was conducted in which one group of students used computer conferencing for continual public exchanges of ideas through asynchronous meetings, and another group used class discussion groups, while attempting to solve a legal problem in a course in consumer law. Student success rates for solving the assigned problem…

How the self-explanation process relates to learning and subsequent problem-solving performance was studied in two experiments with college students to examine whether students taught to self-explain during a study phase show greater test gains than control group counterparts; this is an attempt to replicate the results of M. T. H. Chi and others.…

Two experiments are reported that compared incentive motivation for studying, based on a weekly quiz in a course, to a metacognitive strategy for studying, based on identifying key terms, and providing definitions and elaborations as homework. In the first experiment, with a sample of 109 students enrolled in an educational psychology class, the…

This report presents the findings of a study that examined the impact of compensatory education services on children's academic achievement in grades 1 to 6. Examination of data from the 1976-79 Sustaining Effects Study of Title I revealed the following major conclusions: (1) small positive gains in reading achievement are related to participation…

Self-instructional booklets simulating computer-assisted instruction (CAI) were used to teach four basic concepts in science to first graders in three treatment groups which received different types of feedback--hints, correct answers, and right or wrong. A control group received neither instruction nor feedback. A multiple-choice test was…

One of the important components of the elaboration theory (Reigeluth, 1979) is the synthesizer, which provides information to relate and integrate a set of concepts and which can appear in different formats. This study investigated the effectiveness of three formats of post-instruction synthesizer on student recall of definitions of concepts and…

The influence of change in teachers' instructional effectiveness upon the relationship between their expectations for students' performance and student achievement outcomes is investigated. Data were gathered from 44 intermediate and high school level teachers who particpated in an inservice training workshop on mastery learning strategies.…

THE PURPOSES OF THE PROJECT WERE TO (1) DESIGN A SELF-PACED TEACHING DEVICE FOR THE BLIND WHICH WOULD ALLOW THE EVALUATION OF SYSTEMATIC TRAINING IN PREREADING TACTUAL DISCRIMINATION AND BRAILLE CHARACTER DISCRIMINATION AS BOTH RELATE TO SUBSEQUENT ABILITY TO LEARN TO READ BRAILLE SYMBOLS, (2) DESIGN AN ELECTRONIC AUTOMATED DEVICE WHICH ALLOWS THE…

A DESCRIPTIVE EVALUATION HAS BEEN MADE OF A NEW YORK CITY COOPERATIVE PROGRAM TO MOTIVATE POTENTIAL DROPOUTS AND TO PROVIDE THEM WITH SUPERVISED, PAID EMPLOYMENT AS AN INTEGRAL PART OF THEIR HIGH SCHOOL EXPERIENCE. THE BASIC STUDY SAMPLE WAS CONFINED TO GROUPS, BOYS AND GIRLS, IN FOUR PREDOMINANTLY NEGRO-PUERTO RICAN HIGH SCHOOLS IN NEW YORK CITY.…

The evaluation design, which prescribes when and from whom to gather data, is described as significant because it can lend credibility to evaluation results. The objectives of this booklet are to aid the evaluator in: choosing a design; putting it into operation; and analyzing and reporting the data. Examples include both formative and summative…

The failure of educational research to fully allow for limitations in methodology when drawing conclusions is faulted. In addition to this, a failure on the part of the media--educational and other--to fully publicize these limitations is also criticized. Methodological shortcomings of the 1977-78 American Institutes of Research (AIR) study of…

First grade children from two Head Start (HS) groups and one non-Head Start (NHS) group were administered a battery of tests for the purposes of (1) comparing the developmental status of HS and NHS subjects, (2) examing patterns of specific learning disabilities among HS and NHS children, (3) determining the stability coefficients of selected…
