The authors' data contain inter- and intra-class variations in experiments to which students in a principles of microeconomics course were exposed. These variations allowed the estimation of the effect on student achievement from the experimental treatment generally, as well as effects associated with participation in specific experiments. The…

Promoting self-determination has become a best practice in special education. There remains, however, a paucity of causal evidence for interventions to promote self-determination. This article presents the results of a group-randomized, modified equivalent control group design study of the efficacy of the Self-Determined Learning Model of…

With increased demand for improved early childhood education services, it is important to better understand the essential professional development resources that have the greatest impact on both teacher and child outcomes. This study compared the effectiveness of two teacher-training models in bilingual Migrant and Seasonal Head Start and Head…

The Communities In Schools (CIS) Model of Integrated Student Supports aims to reduce dropout rates by providing students with integrated and tiered support services based on their levels of need. The model includes preventive services that are available to all students (Level 1 services) as well as intensive, targeted, and sustained services…

This study examined the efficacy of a core kindergarten mathematics program, Early Learning in Mathematics (ELM), a 120-lesson program with four content strands: (a) number operations, (b) geometry, (c) measurement, and (d) vocabulary. The study utilized a randomized block design, with 129 classrooms randomly assigned within schools to treatment…

The transgenic mouse model is useful for studying the causes and potential cures for human genetic diseases. Exposing high school biology students to laboratory experience in developing transgenic animal models is logistically prohibitive. Computer-based simulation, however, offers this potential in addition to advantages of fidelity and reach.…

Safe School Ambassadors (SSA) is a student-centered bystander education program developed by Community Matters to reduce bullying/mistreatment and enhance school climate. A two-part program evaluation was designed to assess the efficacy of the program's logic model and its impact on school-level discipline indicators. For the first part, a…

In a pilot study at El Centro College, an urban college in the Dallas County Community College District, students in a new-to-college educational framework class were offered an intervention intended to enhance the academic advising process. The intervention consisted of in-class career services advising, degree selection, degree planning, course…

Promoting self-determination has been identified as best practice in special education and transition services and as a means to promote goal attainment and access to the general education curriculum for students with disabilities. There have been, however, limited evaluations of the effects of interventions to promote self-determination on…

The ESEA Blueprint for Reform states that teachers need "effective, ongoing, job-embedded, professional development that is targeted to student and school needs… [and] aligned with evidence of improvements in student learning." Unfortunately, the professional development approaches advocated, though sensible and compelling in theory,…

The purpose of this study was to examine the relative effects of the single-focus interventions (vocabulary and comprehension) and the streamlined multi-component model. The program of research included a development and pilot phase, an initial experimental study and a follow-up study to further refine and test the model. Results presented here…
