This paper reports findings of a study that examined student performance and attitudes towards the use of information technology in virtual and conventional settings. Students were preservice undergraduate and graduate students enrolled in an educational media and technology course. All were fulltime, on-campus students, but one group completed…

This paper discusses the results of a study of the relationships between teacher behaviour and the level of play engagement in two- and three-year-old children in Dutch childcare centres. We found that the continuous proximity of the teacher had the greatest impact on the level of play engagement, while the teacher's walking around and only brief…

An interdisciplinary environmental education program was introduced on an experimental basis into high school social studies and science courses in an effort to produce competencies in environmental problem solving. Ninth and tenth grade classes in a suburban school district in Atlanta participated in the study. The ninth graders were of average…

This study was mounted to assess the validity of standard score transformations of raw test scores and test bias on the 1970 edition of the Metropolitan Achievement Test Battery, in the context of a controversial federally funded compensatory education program, the Educational Voucher Demonstration (EVD). On an individual level the validity of the…

Effects of experimental learning environments on students' perceptions of themselves and others were evaluated using a nonverbal self-social constructs test. Data were collected from 4000 students representing elementary schools with traditional or experimental learning environments. The experimental environments allowed parents and students to…

This codebook for a machine-readable data file contains the frequencies for the value of 23 variables for each of the 3,173 student-activity evaluation interactions (cases) for the 44 activities in the Human Sciences Knowing Module. Students rated each activity on an eight-item, Likert-type scale and responded to open-ended questions about the…

This codebook for a machine-readable data file contains frequencies for the values of 1,275 variables for 734 student cases that comprise the field-test data from the BSCS Human Sciences curriculum project. This three-year interdisciplinary science curriculum, designed for 11- to 14-year-olds, was field-tested in seven middle and junior high…

This codebook for a machine-readable data file contains eight variables that describe the characteristics of 623 activities or activity parts that comprise the activities used in the field test of the BSCS Human Sciences Program, 1973 to 1976, and 1977, in middle and junior high schools in the United States. The file also includes 52 variables…

Data on graduate science enrollment and support as of the Fall 1978 is reported. Surveys were sent to 418 schools--285 graduate schools and 133 medical colleges--which included 8,242 graduate departments. After a review of the survey background and the scope, response rates, and imputation effects, Section Two classifies each institution and…

The results of the secondary analysis of data obtained in a study of Head Start graduates in the public schools are summarized in this report. Due to unforseen circumstances, the original longitudinal research design was not fully implemented, and the study was constrained to one administration of a test battery to first-grade students. The…

The long-term stability of students' evaluations of instructional effectiveness was investigated. The focus was on the extent and nature of realtionships between end-of-term and retrospective ratings. Ratings given by alumni one year after program completion were compared with ratings given by these individuals in 85 undergraduate and graduate…

The statistical properties of two methods of estimating gain scores for groups in quasi-experiments are compared: (1) gains in scores standardized separately for each group; and (2) analysis of covariance with estimated true pretest scores. The fan spread hypothesis is assumed for groups but not necessarily assumed for members of the groups.…

The feasibility of criterion referenced testing is held to be dependent on the tenability of two postulates: (1) that bias can be controlled in a principled manner from one test to the next; and (2) that one mental process measured by such tests may lawfully interact with another. Without the first postulate, criterion scores could not be…

The first set of National Longitudinal Study (NLS) data was analyzed to derive composite scores to be used in subsequent analyses. The composites include a general ability measure, a socioeconomic status (SES) index, and factor scores from factor analyses of sets of question items measuring goals, attitudes, and other psychological attributes. The…

The equivalency of achievement results obtained under Title I evaluation models A1 and C1 was examined. Data were reading comprehension and arithmetic scores on the Iowa Tests of Basic Skills, administered to fourth, sixth, and eighth grade students in St. Louis, Missouri. The St. Louis Public Schools had traditionally used Model A1, a…
