The purpose of this report is to describe the work that has been done so far on learning progressions in science, examine the challenges to developing usable learning progressions, determine if further investments are warranted, and if so, what investments are needed to realize their promised benefits. The report examines the quality and utility…

The emerging use of portable digital devices by students, parents and teachers, is forcing schools to develop real-time communication systems that integrate technology into the general operations of schools, and contemplate governing policies and procedures to sustain and guide the challenges of these new technologies. This study contributes to…

Many reformers suggest that urban district central offices would strengthen teaching and learning districtwide if they operated as "learning organizations." But what does it mean for a school district central office to operate as a learning organization? This article draws on research about learning theory and school district central offices to…

This paper has five objectives: (a) to review the scientific background of, and major findings reported in, Medical Problem Solving, now widely recognized as a classic in the field; (b) to compare these results with some of the findings in a recent best-selling collection of case studies; (c) to summarize criticisms of the hypothesis-testing model…

Assessments labeled as formative have been offered as a means to improve student achievement. But labels can be a powerful way to miscommunicate. For an assessment use to be appropriately labeled "formative," both empirical evidence and reasoned arguments must be offered to support the claim that improvements in student achievement can be linked…

In this commentary, the author addresses what is referred to as the deterministic input, noisy "and" gate (DINA) model. The author mentions concerns with how this model has been formulated and presented. In particular, the author points out that there is a lack of recognition of the confounding of profiles that generally arises and then discusses…

Rupp and Templin (2008) do a good job at describing the ever expanding landscape of Diagnostic Classification Models (DCM). In many ways, their review article clearly points to some of the questions that need to be answered before DCMs can become part of the psychometric practitioners toolkit. Apart from the issues mentioned in this article that…

This paper explores the relationship between H. C. Orsted's research and teaching programme in order to uncover the way he attempted to sustain a dynamical approach to science through his lectures and textbooks. The main focus is the relation between Orsted's didactics as presented in his textbooks and other documents, his pedagogic activity, and…

Evidence seems to be a particularly newsworthy topic these days, prominent in stories about weapons of mass destruction, the President's record in the National Guard, Martha Stewart's stock sales, global warming and the EPA, and so forth. "Evidence," not surprisingly, derives from "evident," which the American Heritage Dictionary defines as…

The No Child Left Behind Act is comprised of four pillars, one of which is "proven education methods." This paper attempts to provide a historical context for the development of evidence-based education by examining its foundation in medical practice. Next, the rationale for evidence of educational effectiveness based on a scientific…

Over the past 20 years, alternative certification for teachers has emerged as a major avenue of teacher preparation. The proliferation of new pathways has spurred heated debate over how best to recruit, prepare, and support qualified teachers. "Alternative Routes to Teaching" provides a thorough and dispassionate review of the research evidence on…

Since boys are more commonly diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) than girls, the majority of theories and published research studies of ADHD have been based on samples comprised primarily (or exclusively) of boys. While psychosocial impairment in girls with ADHD is well established, the neuropsychological and…

Dual and concurrent enrollments enable students to earn postsecondary credits while still in high school. The 2006 Perkins legislation encourages such enrollments as a component of programs of study. There is evidence that students who earn dual enrollment credits have slightly (typically 4% to 5%) more positive outcomes in postsecondary education…

This pilot study focuses on the potential of Evidence-based Dialogue Mapping as a participatory action research tool to investigate young teenagers' scientific argumentation. Evidence-based Dialogue Mapping is a technique for representing graphically an argumentative dialogue through Questions, Ideas, Pros, Cons and Data. Our research objective is…

This report summarizes findings from a two-year study of Chicago's Excellence in Teaching Pilot, which was designed to drive instructional improvement by providing teachers with evidence-based feedback on their strengths and weaknesses. The pilot consisted of training and support for principals and teachers, principal observations of teaching…
