Even though 34 states and the District of Columbia have No Child Left Behind Act waivers in hand, many of them are still negotiating with the U.S. Department of Education over their teacher evaluation systems--a crucial component if they want to keep their newfound flexibility. More than six months after waiver recipients turned in their…

With nightmare visions of a gunman stalking school halls, districts often rush to hire police officers to patrol their campuses after news of a school shooting. Critics of that impulsive response, which has been in high gear nationwide since the Sandy Hook Elementary School shootings in December, acknowledge the concern for student and staff…

A group of states has joined forces to arrange the purchase of an unusually comprehensive set of educational-technology devices and services, in a compact that could foreshadow other cooperative efforts by state and local governments attempting to turn the digital-procurement process to their advantage. The initial partners in the multistate…

Emerging technology and research on learning have the potential to dramatically improve assessments, if educators and policymakers take a more balanced approach to using them. That's the conclusion of two years of analysis by the Gordon Commission on the Future of Assessment in Education, a panel of top education research and policy experts that…

Even as they seek to quantify the impact of across-the-board federal budget cuts on K-12 programs, some of the nation's neediest school districts are bracing for tough choices. The pinch from sequestration--or "the sequester," in Washington shorthand--is expected to be particularly painful for districts that depend on the most on the federal…

Schools are working to incorporate more multimedia into classrooms, upgrade online professional development, and do a better job using data to improve student achievement. Even though nearly every school in the country is now connected to the Internet, not all of them have the kind of connections that allow teachers and students to make full use…

New York is ahead of most states in its work to design detailed curricula and professional development for the common core and to build brand-new tests to reflect them. What's unfolding in the Empire State as a result of that work illustrates the way the common standards can pressure changes in the education landscape, and torque the tensions…

The 16 Race to the Top district winners, pushed by $400 million in federal grants that put a premium on personalized learning, are embarking on vastly different makeovers of the classroom experience--from districtwide approaches to a narrower blueprint focused on middle school math. Despite the divergent approaches, a review of the winning…

When science, technology, engineering and mathematics (STEM) education is discussed in the K-12 sphere, it often seems like shorthand for mathematics and science, with perhaps a nod to technology and even less, if any, real attention to engineering. But recent developments signal that the "e" in STEM may be gaining a firmer foothold at the…

One thing is immediately apparent when Erica Vuolle teaches: Not a moment of time is wasted. Ms. Vuolle is among the 40 teachers-in-training at the Match Teacher Residency, a teacher education program run by the Boston-based Match Education, a nonprofit charter-management organization that requires candidates to practice and master a repertoire of…

The first round of this year's high-school-match notifications in New York City's massive, district-wide school choice process went out to students this month, sparking celebration, consternation, and a renewal of concerns about unequal access to the city's best schools. The Big Apple's school-matching system is certainly on a New York scale, with…

We present a number of simple demonstration experiments recorded with high-speed cameras in the fields of gas dynamics and thermal physics. The experiments feature relatively slow combustion processes of pure hydrogen as well as fast reactions involving oxy-hydrogen in a stoichiometric mixture. (Contains 4 figures.)

An active learning sequence based on the predict-observe-explain teaching strategy is applied to a lesson on buoyant force. The results obtained clearly justify the use of this teaching method and suggest devising a series of activities to enable more effective removal of students' commonly held alternative conceptions regarding floating and…

Research has shown that students have difficulty understanding the underlying process of the photoelectric effect. Thus, this study sought to utilize an inductively situated lesson for teaching the photoelectric effect, hypothesizing that this type of enquiry would help learners delve deeper into the principles of the phenomenon and provide a…

We have developed an exciting non-traditional experiment for our introductory physics laboratories to help students to understand the principle of conservation of angular momentum. We used electric toy cars moving along a long rotating rod. As the cars move towards the centre of the rod, the angular velocity of this system increases.…
