The Boomerang is a language arts subscription program that provides support for development in spelling, punctuation and grammar for junior high students (7th to 9th grades). Using the practices of copywork and dictation, the Boomerang includes:

Boomerang '98 After over five years of development Boomerang made its first long duration balloon flight above Antarctica in 1998. The '98 instrument consisted of sixteen unpolarized detectors which operated at four different wavelengths, or colors. At the time of its release, the data from this flight was of unprecedented quality. The instrument's sensitivity, frequency coverage, and angular resolution allowed the unambiguous measurement of temperature fluctuations in the cosmic microwave background over a broad range of angular scales.

The goal of the Boomerang program was to rapidly develop and demonstrate affordable and reliable acoustic gun shot detection and localization techniques. The program focused on enhancing the safety of vehicle convoys and increasing situational awareness. Based on previous acoustic shot detection work, Boomerang developed system hardware design and packaging, vehicle integration concepts, user interfaces and signal processing algorithms and software for prototype systems, as well as continued refinement of algorithms, hardware and software to improve system performance and accuracy. Acoustic sensors, mounted in an array at the top of a mast, are used to detect both supersonic shock and sound waves from muzzle blast and then identify the location of the shooter. Users receive simultaneous visual and auditory information about the point of fire from an LED display and speaker. Boomerang systems were tested by warfighters serving in Operation Iraqi Freedom (OIF).

The Boomerang is a digital product only. The issues are posted once per month in a private folder for subscribers. In each issue, you'll find four weeks worth of dictation/copywork passages (one per week with grammar, punctuation and writing notes) as well as a secondary feature: Think Piece questions. These questions help your child think deeply about the content of the book while exploring those thoughts in writing.

The Boomerang should be nearly vertical when releasing. Increasing the tilt angle makes it fly higher and land further back. Holding the boomerang more vertically will make it fly lower to the ground and land more forward. NEVER hold the boomerang horizontally flat like a frisbee. This will cause the boomerang to fly in dangerous swooping and diving flights.

The Boomerang is newly designed this year to give your junior high students both a continued focus on dictation and language arts, while ... providing them with the opportunity to respond to the books they read. Subscribers will receive both the Boomerang digital issue as well as access to the private folder where a book discussion will be led by Julie Bogart.
