The 2013 edition of "Diplomas Count," entitled "Second Chances: Turning Dropouts into Graduates," examines dropout recovery and innovative strategies for returning to the educational fold the 1 million students who leave school without a diploma each year. "Education Week's" journalists investigate interventions that provide second chances to…

President Barack Obama is calling for an ambitious overhaul of the federal E-rate program, a step that many education and technology advocates have been urging for years to improve what they see as schools' badly out-of-date technological capabilities. The administration intends to ask the Federal Communications Commission to consider rechanneling…

Even with nearly 50 schools shutting down at the end of this month, Chicago education officials have been barreling ahead with plans to groom a large crop of high-performing principals that they say represents the most ambitious effort the city has undertaken to upgrade its school leadership ranks. The goal, said Chicago schools CEO Barbara…

Returning from spring vacation, Dowan McNair-Lee's students find their desks in neat rows, facing forward. For the previous seven months, the 8th graders had sat in clusters, facing one another, to facilitate discussion. But janitors used the break to ready the classroom for the year-end tests that are only two weeks away. The new arrangement is…

Should all students take Algebra 2? Florida seemed to say "no" this spring with the passage of a law striking it from graduation requirements. Texas said much the same in legislation Republican Gov. Rick Perry signed this week that also backs away from Algebra 2 for all. Those steps come as the Common Core State Standards for math set the…

With the debut of common assessments less than two years away, states and districts are worried about the accountability systems that hinge on those tests. A growing chorus of policy groups is urging more flexibility in how states evaluate teachers, label schools, and enforce other high-stakes consequences during what's likely to be a messy…

The aim of the paper is to make a critical reading of ecocentrism and its meta-scientific use of ecology. First, basic assumptions of ecocentrism will be examined, which involve nature's intrinsic value, postmodern and modern positions in ecocentrism, and the subject-object dichotomy under the lenses of ecocentrism. Then, we will discuss…

Progressive interpretations of scientific theories have long been denounced as naive, because of the inescapability of meaning variance. The charge reportedly applies to recent realist moves that focus on theory-parts rather than whole theories. This paper considers the question of what "theory-parts" of epistemic significance (if any) relevantly…

In this article we focus on the concept of concept in conceptual change. We argue that (1) theories of higher learning must often employ two different notions of concept that should not be conflated: psychological and scientific concepts. The usages for these two notions are partly distinct and thus straightforward identification between them is…

The relationship between physics and mathematics is hardly ever presented with sufficient clarity to satisfy either physicists or mathematicians. It is a situation that often leads to misunderstandings that may spread quickly from teacher to student, such as the idea that mathematics is a mere instrument for the physicist. In this paper, we…

The content of the expertise which young natural scientists try to gain by doing science in research groups is a relatively little-explored subject. What makes learning in such settings challenging is that a central part of the expertise is tacit. This study employs empirical methods together with a contextualized approach and interdisciplinary…

Various studies have promoted instruction in the history and philosophy of science (HPS) in science classes, but the best way of putting this perspective into practice remains undetermined. To contribute to this issue, we developed a pedagogical project in some high schools in Brazil that aimed to present science content using an…

We discuss how light acquired a velocity through history, from the ancient Greeks to the early modern era. Combining abstract debates, models of light, practical needs, planned research and chance, this history illustrates several key points that should be brought out in science education.

Using history of mathematics for studying concepts, methods, problems and other internal features of the discipline may give rise to a certain tension between descriptive adequacy and educational demands. Other than historians, educators are concerned with mathematics as a "normatively defined" discipline. Teaching cannot but be based on a…

In teaching physics, the history of physics offers fruitful starting points for designing instruction. I introduce here an approach that uses historical cognitive processes to enhance the conceptual development of pre-service physics teachers' knowledge. It applies a method called cognitive-historical approach, introduced to the cognitive sciences…
