In order to provide an on-demand, open electrical engineering laboratory, we developed an innovative software-based Virtual Open Laboratory Teaching Assistant (VOLTA). This web-based virtual assistant provides laboratory instructions, equipment usage videos, circuit simulation assistance, and hardware implementation diagnostics. VOLTA allows…

Direct linkMontague, Marjorie; Krawec, Jennifer; Enders, Craig; Dietz, Samantha – Journal of Educational Psychology, 2014
The effects of a mathematical problem-solving intervention on students' problem-solving performance and math achievement were measured in a randomized control trial with 1,059 7th-grade students. The intervention, "Solve It!," is a research-based cognitive strategy instructional intervention that was shown to improve the problem-solving…

Konstantopoulos, Spyros; Miller, Shazia Rafiullah; van der Ploeg, Arie – Educational Evaluation and Policy Analysis, 2013
Interim assessments are increasingly common in U.S. schools. We use high-quality data from a large-scale school-level cluster randomized experiment to examine the impact of two well-known commercial interim assessment programs on mathematics and reading achievement in Indiana. Results indicate that the treatment effects are positive but not…

Olejnik, Stephen – 1978
The measurement of change in quasi-experimental educational research was discussed. Problems related to measuring change exist to varying degrees in all research designs; these issues are less troublesome in experimental studies because the investigator can manipulate the interest variables and observe their effects on other variables. Measuring…

Hick, Thomas L.; Irvine, David J. – 1978
To eliminate maturation as a factor in the pretest-posttest design, pretest scores can be converted to anticipate posttest scores using grade equivalent scores from standardized tests. This conversion, known as historical regression, assumes that without specific intervention, growth will continue at the rate (grade equivalents per year of…

Richards, James M., Jr. – 1974
Recent research results strongly suggest that the theoretical problems of change measures have limited practical significance for measuring individual growth, and it is important to determine whether this is also the case for measuring school impact. Accordingly, in this study artifical data were used to assess the correlation between several…

Conklin, Jon – 1978
It is unsafe to estimate achievement test norms for fall testing by linear interpolation between norms for the previous spring testing and norms for the following spring. Second grade students were tested in reading and arithmetic in the fall and in the spring to provide pre-test and post-test data for evaluation of academic growth. Three…

Marston, Paul T., Borich, Gary D. – 1977
The four main approaches to measuring treatment effects in schools; raw gain, residual gain, covariance, and true scores; were compared. A simulation study showed true score analysis produced a large number of Type-I errors. When corrected for this error, this method showed the least power of the four. This outcome was clearly the result of the…

PREKINDERGARTENS IN 8 NEW YORK STATE SCHOOL SYSTEMS WERE EVALUATED TO FIND OUT IF THE CHILDREN INVOLVED SHOWED INCREASED CAPACITY TO LEARN, AND IMPROVEMENT IN LANGUAGE AND COGNITIVE SKILLS. 1010 DISADVANTAGED AND 225 NONDISADVANTAGED SUBJECTS WERE RANDOMLY ASSIGNED TO EXPERIMENTAL AND CONTROL GROUPS AND PRE- AND POST-TESTED WITH THE STANFORD-BINET…

Echternacht, Gary – 1979
The role that measurement error plays in the regression effect is discussed with particular reference to the RMC models for evaluating the effects of Elementary Secondary Education Act Title I programs. The norm referenced evaluation model assumes a theory of growth where the relative ranking of students remains the same from pretest to posttest…

Cross, Lawrence H.; Lane, Carolyn E. – 1977
Action research often necessitates the use of intact groups for the comparison of educational treatments or programs. This paper considers several analytical methods that might be used for such situations when pretest scores indicate that these intact groups differ significantly initially. The methods considered include gain score analysis of…

Schutz, Robert W. – 1977
The measurement of change is such a broad topic that this article must limit its focus to a few specific subtopics. These specific topics include: longitudinal research design, attrition in research studies, the statistical analysis of difference scores, and the comparison of analysis of variance (ANOVA) and multivariate analysis of variance…

An application of evaluation methodology to innovative educational programs through a case study of a Chicago suburban high school program for alternative education is presented. The evaluation methodology encompasses the difficulty in combining comparative programs, individual-diagnostic, and individual developmental measures, the selection of…

The second of two reports on a national evaluation of the immediate effects of Project Head Start describes the characteristics of children, families and programs in samples of full-year classes operating in 1966-67 and 1967-68. No control groups were used; comparisons were made within the Head Start sample to see what kinds of classroom…

The first of two reports of a national evaluation of the immediate effects of Project Head Start describes the characteristics of children, families and programs in samples of full-year classes operating in 1968-69. The study identifies changes associated with Head Start participation and the conditions under which these changes were greatest. No…
