The STEM.LD program was funded by a 2020 mid-phase Education Innovation and Research (EIR) grant. It sought to improve student outcomes by strengthening professional learning for teachers and school leaders, expanding STEM curricular resources, and increasing student engagement in rigorous coursework and extracurricular opportunities. A randomized…

The paper examines the goals and effects of early intervention with infants at risk for possible developmental problems. Four components of San Francisco Infant Program are noted: (1) services to children, (2) parent involvement, (3) a transdisciplinary team approach, and (4) a research-based model. The research problems associated with…

A quantitative method, meta-analysis, is used to integrate research findings from a representative group of 38 coaching studies. Because different studies reported results on different scales, effect size was used to transform all results to a common metric. This meta-analysis showed that there are two distinct literatures on the effectiveness of…

This paper compares five growth measures using the High School and Beyond database. The measures are: (1) simple gain (posttest minus pretest); (2) difference between group means; (3) percentage of students who scored higher on the posttest than the pretest; (4) percentage of items missed on the pretest which are subsequently answered correctly on…

Several years ago, California, along with other states, discovered that there was a layering effect of categorical programs, both state and federal. Most programs were aimed at unique populations--disadvantaged, bilingual, etc. This proliferation and the evaluation requirements inherent in each of the categorical efforts created problems of…

This paper explores the difficulties of extending good, workable educational ideas to entire schools or districts. Two restructured schools that participated in a 4-year collaborative project that involved multi-age primary classrooms, inclusion of special-needs students in regular classrooms, and increasing specificity in assessing student…

The communicative approach to second language instruction has gained disproportionate publicity in the language teaching profession through the Communicative Teaching Project in Bangalore, India. Because of a series of articles and books and presentations at conferences advertising the project's alleged innovativeness and effectiveness, it has…

A persistent problem in aptitude-treatment interaction (ATI) research has been the need for a better conceptualization of instructional treatments. The concerns are important in the analysis of instructional treatments: the importance of considering the psychological processes called upon by the instructional treatment, and the ecological validity…

This paper discusses the results of a study that investigated the progress of 51 children receiving long-term dynamically-oriented therapy at a naturalistic "real world" clinic. The orientation of the Outpatient Clinic of the Yale Child Study Center is primarily long-term, psychodynamic treatment. Parents and clinicians completed…

Perhaps no facet of long-term care (LTC) research has received as much attention as the evaluation of community-based LTC demonstrations. Recent thinking has called into question the validity and policy relevance of the findings of these studies, yet their efforts will continue to receive strong financial backing. The time has come for LTC…

Self-selection bias poses a major threat to the validity of research findings in naturalistic, quasi-experimental, or single-group designs. A new method of addressing self-selection bias in naturalistic evaluations of prevention programs was implemented. The study, involving voluntary exposure to multicomponent interventions, was developed and…

A review of the literature is presented on developmental mathematics courses in two- and four-year colleges and universities. The paper is organized within the categories of status studies, placement, program evaluation, class management, student characteristics, and thought processes. Highlights of the report include: (1) an average of 2.0…

Following a discussion of various methods of evaluating the effectiveness of developmental programs, this paper presents a research design for the evaluation of a developmental math program. First, the paper examines the objectives and benefits of conducting formative and summative program evaluations. The paper then identifies the single group…

In the area of aptitude-treatment interaction (ATI) research, an outcome variable which has received relatively little attention is differential student learning times, or students' relative learning efficiency on one treatment as opposed to another. Although it has been argued that learning times are not appropriate variables for evaluating…

In 1990, Milwaukee (Wisconsin) became the site of the first publicly funded school-choice program providing low-income parents with vouchers that could be used to send their children to secular, private schools. An evaluation of Milwaukee's school-choice experiment was conducted by a team of researchers, headed by John Witte at the University of…
