We report the results of a preregistered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no 2 consecutive problems require the same…

Lessons about elementary particles at the secondary school level can degenerate into listing a zoo of particles and reactions, resulting in disorganized and rather meaningless knowledge. A more powerful way is to focus on conservation laws, symmetries and reaction diagrams. The conservation laws and symmetries provide generalizing power that…

An educational study of the barometric effect of cosmic rays was carried out using an inexpensive experimental set-up that allowed for long-term monitoring of atmospheric pressure and cosmic ray flux as measured in a Geiger counter. The investigation was intended as a pilot study in view of ongoing involvements of high-school teams operating…

In 1985-86 several small school districts in rural New York State began cooperating to offer advanced high school courses via audio-graphic telecommunications. Evaluation of the Tele-Learning project's second year used a case study approach to examine four diverse programs: advanced placement English, advanced placement calculus, Spanish III, and…

A verbal and e-mail survey was conducted of 30 senior high teachers in Alberta who teach computer programming courses in the Career and Technology Studies curriculum, in order to ascertain what courses at the intermediate and advanced levels were being offered, what programming languages were being used, why teachers selected the particular…

Salters-Nuffield Advanced Biology is a new advanced level biology course, piloted from September 2002 in England with around 1200 students. This paper discusses the reasons for developing a new advanced biology course at this time, the philosophy of the project and how the materials are being written and the specification devised. The aim of the…

Recognizing the challenges rural districts face in providing broad curricular offerings and supplemental educational services to students, in 2007, the 80th Texas Legislature authorized the creation of a pilot program designed to provide technology-based supplemental educational services to rural school districts that show an overall academic need…

A scan of the experiences that colleges have had with school/college programs and/or projects was conducted in the fall/winter of 2005-06. The scan was conducted under the leadership of Vice Presidents Academic of the Ontario colleges of applied arts and technology. The purpose of the scan was to gather input so that it could be compiled and made…

In 2007, the Texas Legislature (80th Texas Legislature, Regular Session, 2007) authorized the creation of the Texas Rural Technology (R-Tech) Pilot program, which provides $8 million in funding to support rural districts in implementing technology-based supplemental education programs. In order to be eligible for funding, districts must have…
