Too often, in the teaching of U.S. history, inclusion of other cultures in the curriculum passes for synthesis. True synthesis incorporates various elements of human experience (events, institutions, groups) into an explanatory narrative. Understanding requires a sense of the differences that mark and make U.S. society. (MSE)

Presents a synthesis of what is known about Title I schoolwide programs, focusing on characteristics of schools and districts implementing schoolwide programs, programmatic and organizational characteristics of the programs, and evidence of program effectiveness. Cautions in interpreting the evaluation findings are presented, and educational…

Critiques the conclusions of S. Veenman (1995) about multigrade classes and suggests that selection bias and lower-quality instruction should be included as part of the explanation for his findings of no difference. Indicates that multigrade classes have at least a small negative effect on achievement and potentially negative effects on teacher…

D. Mason and R. Burns (1996) have concluded that multigrade classes have a slightly negative effect on students' achievement. However, a reanalysis, based on meta-analytic procedures, of the available studies shows the average weighted effect sizes to be essentially zero or close to zero. Contains 51 references. (SLD)

A simple chemical sensor-related experiment rooted in the synthesis of polymeric materials for use in either an advanced high-school or undergraduate college laboratory is presented. Students are introduced to and combine to the concepts of the chemical sensor, polymer chemistry, spectroscopy, metal chelates, and quantitative analytical methods.

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…

A set of sophisticated and realistic laboratory simulations is created for use in freshman- and sophomore-level chemistry classes and laboratories called 'Virtual ChemLab'. A detailed assessment of student responses is provided and the simulation's pedagogical utility is described using the organic simulation.

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…

The purpose of this report is to document the participation and performance trends over time for students with disabilities, progressing from school year 2001-02, a base year for determining AYP goals under NCLB, through school year 2004-05, the third year that states reported after the NCLB baseline year (VanGetson & Thurlow, 2007). Within…

Purpose: The purpose of this research is to show that for the successful development of socio-technical systems it is essential that various stakeholders are able to integrate their different knowledge and perspectives. A method that supports knowledge integration in the course of introduction and development of socio-technical systems is the…

This paper reports the development and evaluation of an observation guide that draws on qualitative techniques of participant observation and semistructured interviewing to help anyone interested in visiting and understanding schools to develop a "big picture" profile quickly and efficiently. The guide reflects the philosophy of E.…

Two kinds of perspectives governing the provision and preservation of knowledge, a universal and an ecological perspective, are discussed in this paper. In the first case, scientific observations are represented through a semantic interpretation of facts. This is illustrated with a series of experiments on semantic feature perception in the recall…

Based on a prior model on modularity of the brain, a new modular model of intrapersonal communication was developed which focuses on brain processing, encompassing both the structures and the functions of those structures in the creation of messages. The modular mind is a bio-social model of communication which presupposes a relationship between…

This paper focuses upon the perceptions and the actions of the elementary school principal in the change process. Perceptions of change itself, of control, of the school system, and of the school staff are critical to his/her effectiveness in implementing change. To create an institutional climate that supports change, the principal must provide…

Advocates the abandonment by teachers of some of their traditional viewpoints (historical and cultural), goals, and methods and, through the use of technology in some cases, proposes developing closer ties to the children and the community of which they are a part. (SF)
