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…

Under the "Math Science Partnership Grant," the Maui Hawaii Educational Consortium sought scientifically based evidence for the effectiveness of Carnegie Learning's "Cognitive Tutor[R]" (CT) program as part of the adoption process for pre-Algebra program. During the 2006-2007 school year, the researchers conducted a follow-on…

Objective: The authors analyze the occurrence of grade repetition and inattention in children diagnosed with neurofibromatosis type 1 (NF1). Method: The participant group consisted of 310 patients with NF1 and a control group of 242 individuals. The number of grade repetitions for each participant during his or her time in elementary, middle, and…

The effectiveness of students' evaluations of teaching effectiveness (SETs) as a means of enhancing university teaching was studied, with emphasis on the multidimensionality of SETs, an Australian version of the Students' Evaluations of Educational Quality instrument (the ASEEQ), and the 1986 feedback/consultation intervention of R. C. Wilson.…

A context in which existing items may provide a convenient source of questions for questionnaires was explored through a case study making use of existing comparison groups.

The Speech Reception Test was developed to measure an individual's ability to hear and understand conversational speech. The equipment used to record the test is described in detail, and data are given for the results of the test given to 100 normal-hearing college students.

Researchers used a pretest-posttest comparison to evaluate the effectiveness of monetary rewards in Project ALIVE (Atlantans Learning in a Vocational Environment), a nine-week summer program that combined education, employment, and career training for economically disadvantaged youth in grades 8-12. The project was jointly offered by the Atlanta…

An empirical study was conducted in order to obtain treatment effect estimates with the Special Regression model for groups in which there was no treatment. General mathematics test scores were obtained from 730 ninth graders in city schools somewhat similar to Title I schools, but in which no special treatments were given. Hypothetical…

The presence of artifactual bias in analysis of covariance (ANCOVA) and in matching nonequivalent control group (NECG) designs was empirically investigated. The data set was obtained from a study of the effects of a television program on children from three day care centers in Mexico in which the subjects had been randomly selected within centers.…
