Most of the variance in educational effectiveness studies is inexplicable in terms of influences that can be measured and controlled. Nevertheless, it is still possible to design educational policy that will function well under conditions of uncertainty. (Author/RLV)

The viewpoints of contributors to the forum are reviewed. Many of the disagreements represent fundamental differences in what constitutes evaluation. All four authors agree that the formative/summative distinction is useful and will continue to be an important concept in program evaluation, although the distinction needs greater clarification.…

Case examples in the articles in this volume are analyzed in the mixed-method conceptual frameworks presented in the early chapters. The richer understanding derived from these approaches support the call to advance mixed-method inquiry beyond models and toward inquiry attributes that can be combined. (Author/SLD)

Presents a design framework that incorporates integrated structures for modeling knowledge and skills, designing tasks, and extracting and synthesizing evidence. Illustrates these ideas in the context of a project that assesses problem solving in dental hygiene through computer-based simulations. (SLD)

Describes a "synthesis display," a literature-related activity that helps students who are acquiring English join in the reading class while simultaneously serving the needs of proficient speakers. (MM)

Stresses that metaphorical thinking encourages students to see relationships and requires them to use higher level critical thinking, particularly analysis and synthesis. Describes strategies to get students to think metaphorically in order to understand the elements of Greek tragedy. (MS)

When the process of publication favors studies with small p-values and large effect estimates, combined estimates from many studies may be biased. This paper describes a model for estimation of effect size when there is selection based on one-tailed p-values. (SLD)

Problems and illustrations are presented from a meta-analysis of crime reduction programs. Eight criteria are specified for including studies in a meta-analysis, and some problematic studies are discussed using the criteria. Rules for handling problem studies in order to retain consistency throughout the analysis are discussed. (SLD)

Methods for recording information derived from focus groups are described as follows: (1) transcribe the entire discussion from a tape; (2) expand reporter's notes by using a tape; and (3) work from reporter's notes only. Three approaches are also suggested for synthesizing the discussion into an accurate text. (SLD)

Synthesizes the long-term findings of three major evaluations of programs that began in the late 1980s and were designed to improve the self-efficacy of teenage mothers on welfare. Economic outcomes for the mothers improved over time, and the interventions had some positive effects, although they did not affect fertility. (SLD)

Discusses reason-driven, dichotomized attributes of the 20th Century. Asserts that the 21st Century should be the age of synthesis. To achieve that end, proposes three major tasks of education: Educating the whole person, building progressive self-identity, and developing strategies for productive conflict solution. (PKP)

The solvent-free or solid-state reaction systems like the Baeyer-Villiger rearrangement have become popular in the synthetic organic community and viable option for undergraduate laboratory series to reduce waste and cost and simplify reaction process. The reaction is an efficient method to transform ketones to esters and lactones.

Background/Context: Although the importance of facilitating transfer from community colleges to 4-year institutions is almost universally accepted, there is little consensus on how to measure transfer success or evaluate policies aimed at assisting students in making this educational transition. Despite the increasing attention on transfer in…

Biodiesel was synthesized by transesterification of waste vegetable oil using common glassware and reagents, and characterized by measuring heat of combustion, cloud point, density and measuring the heat of combustion and density together allows the student the energy density of the fuel. Analyzing the biodiesel can serve as a challenging and…

Federal legislation requires that all students, including students with disabilities, be included in all state and district-level accountability systems. Many students can take the regular assessment with or without accommodations, but some students with disabilities need alternate ways to access assessments. For the past several years, states…
