Assessment serves many purposes in the elementary classroom. Formative assessment, often called assessment for learning, is characterized by its primary purpose--promoting learning. It takes place both formally and informally, is embedded in various stages of an instructional cycle, informs the teacher about appropriate next steps for instruction,…

Background: Return on investment (ROI) is one of the most popular evaluation metrics. ROI analysis (when applied correctly) is a powerful tool of evaluating existing information systems and making informed decisions on the acquisitions. However, practical use of the ROI is complicated by a number of uncertainties and controversies. The article…

Many treatment programs for individuals with an autism spectrum disorder (ASD) target social skills, and there is growing attention directed toward the development of specific interventions to improve social skills and social interactions in this population (Hestenes & Carroll, 2000; Strain & Hoyson, 2000). However, there are limited tools…

Aim: This paper is a systematic review of physical activity measurement instruments for field-based studies involving children with cerebral palsy (CP). Method: Database searches using PubMed Central, MEDLINE, CINAHL Plus, PsycINFO, EMBASE, Cochrane Library, and PEDro located 12 research papers, identifying seven instruments that met the inclusion…

We present a data-based perspective concerning recent (e.g., 2008) "Maclean's" magazine rankings of Canadian universities, including cluster analysis of the 2008 data. Canadian universities empirically resemble and relate to each other in a manner different from their formal classification and final rank ordering in the…

New York's Cornell University spends millions of dollars and thousands of staff and volunteer hours to produce more than 1,400 events around the world each year. That's one event every six hours. Is it worth it? Do the 40,000 alumni, parents, and friends who attend feel closer to Cornell after these events? Do they disengage because Cornell didn't…

Describing, explaining, and discussing various modern indices of scholarly impact as accomplished by Ruscio, Seaman, D'Oriano, Stremlo, and Mahalchik (this issue) is highly commendable, as such measures get increasingly important in hiring and promotion decisions. The author agrees with almost all points made in the target article, except the…

Purpose: This study compared the development of essential elements of narrative skill in children from African American English (AAE)- and general American English (GAE)-speaking communities using an innovative elicitation and evaluation protocol consisting of four key indices of narrative language: (a) reference contrasting, (b) temporal…

Damage in polymeric coatings, adhesives, microelectronic components, and composites spans many length scales. For small scale damage, autonomic self-healing can repair multiple damage modes without manual intervention. In autonomic self-healing materials, a healing response is triggered by damage to the material. Size scale considerations, such as…

Collaborative systems are widely used today in various activity fields. Their complexity is high and the development involves numerous resources and costs. Testing collaborative systems has a very important role for the systems' success. In this paper we present taxonomy of collaborative systems. The collaborative systems are classified in many…

A method is presented for marginal maximum likelihood estimation of the nonlinear random coefficient model when the response function has some linear parameters. This is done by writing the marginal distribution of the repeated measures as a conditional distribution of the response given the nonlinear random effects. The resulting distribution…

In this theoretical paper, I present a short critical review of research on calibration. Based on this conceptual analysis I argue for two extensions of this construct: In addition to traditional applications, the methodology should be transferred to also measure calibration between students' metacognitive control processes (traditionally, only…

Two large surveys of children and adolescents in the general British population is used to evaluate the dimensionality of the total difficulties score of the Strengths and Difficulties Questionnaire (SDQ). The findings support the use of SDQ as a measure of child mental health.

Pundits, politicians, and business leaders continually make claims for what standardized tests can do, and those claims go largely unchallenged because they are in line with popular assumptions about what these tests can do, what the scores mean, and the psychology of human motivation. But what most of what these opinion leaders say--and the…

Much grading of student work is based, overtly or tacitly, on assumptions derived from scientific measurement. However, the practice of grading and the cumulation of grades into an overall index of achievement are socially constructed activities that fall a long way short of what is expected of scientific measurement. If scientific measurement is…
