Lighting the world with molecules

Efficient lighting and display have become important concerns in the energy-starved modern world. This has led to new paradigms in lighting and display technologies. Organic molecules provide a new class of active materials for such technologies. This article gives the basic science behind the design of such molecular materials used in displays and lighting.     

Can a Teacher‐Led State Assessment System Work?

Recent implementation of Nebraska's Standards-based Teacher-led Assessment and Reporting System (STARS) introduced a unique opportunity to examine the benefits and drawbacks of a teacher-led state assessment system. STARS is unique among state assessment systems in that statewide tests are replaced by locally developed assessments designed by teachers. Benefits of this system are found to be greater teacher use of results for instructional planning, greater diagnostic utility of the assessments, and gains in assessment literacy. Disadvantages include the time-consuming and stressful nature of creating localized assessments. Compatibility of STARS with the requirements of the No Child Left Behind Act are discussed.     

Extended Test Time and postsecondary Students with Learning Disabilities: A Model for Decision Making

The most frequently requested accommodation among students with learning disabilities (LD) in postsecondary settings is extended test time. The frequency with which this accommodation is requested and granted compels disability service providers to become knowledgeable about the factors that influence the need for, and appropriateness of, the accommodation. Moreover, the synthesis of these factors becomes the basis for determining if the accommodation is reasonable under federal law. The purpose of this article is to present a step‐by‐step model to be used as a decision‐making process when considering the accommodation of extended test time for postsecondary students with LD. The model is designed to assist disability service providers in the analysis and synthesis of information collected from (1) the student's diagnostic evaluation, (2) the course or classroom test to be accommodated, and (3) student interviews. A list of diagnostic tests from the four most frequently administered test batteries used with adults is provided, along with a concise explanation of how characteristics of LD impact reading, writing, and math, and relate to the need for extended time. This information can be used to determine if extended test time is a reasonable accommodation and to estimate how much additional time to provide.     

对我国运动员进行心理表象训练新程序的理论探讨

表象训练是体育运动实践中运用最广泛的训练方法之一。我国在此领域远远落后于日本，其主要因素包括表象训练的方法、个体差异和情境因素：日本新近开发的心理表象训练程序(简称MITP)，几经实践运用，不仅训练效果良好而且在运动训练和比赛心理的理论方面产生了积极的影响，检验了有关表象训练的理论问题，认为动觉表象、视觉表象和想象表象有机结合是提高心理训练效果的良好途径；对MITP作一些理论探讨，目的在于为我国体育运动心理学理论建设提供一点参考。
