Einstruction was an American educational technology company with offices in Denton, Texas, Scottsdale, Arizona, Fort Wright, Kentucky, and Paris, France. History eInstruction was founded in 1981 by computer science professor Darrell Ward. In 2000, Ward and his team developed student response systems in education, with the creation of a hand-held "clicker" system called CPS (Classroom Performance System). In addition to CPS and other interactive classroom technologies, Einstruction worked with educators providing professional development and training. Einstruction was purchased by Turning Technologies in 2013. Products eInstruction introduced a wireless student response system intended to help educators engage and involve students using real-time feedback. In the 1990s, eInstruction sold a radio frequency (RF) response system manufactured by Fleetwood. During the late 1990s, eInstruction began to develop its own student response units that were infrared (IR) instead of RF. At that point, only six student response units could be used concurrently. In 1999–2000, eInstruction modified the IR signal allowing the system to receive up to 32 responses. eInstruction released a chalkboard tablet in 2003. In 2003, eInstruction partnered with Fleetwood to build an RF version of the IR student response system for the K–12 marketplace. In 2004, Fleetwood built an RF response system for eInstruction designed specifically for the higher education market. The company was awarded a U.S. patent for its mobile interactive whiteboard in 2005. In 2006, eInstruction acquired FS Creations, which developed the Examview test bank. eInstruction acquired Interwrite Learning in 2008, which included GTCO CalComp. GTCO produced tablets with wireless and Bluetooth connectivity. In 2009, eInstruction released a mobile interactive whiteboard tablet, as well a system which allowed multiple students to use the same board simultaneously. There was also a mobile add-on, which allowed various smart device to be used in interactive activities and assessments. eInstruction also created the online resource community eI Community, the enterprise-based administrator tool eI Cornerstone Education Suite, and the Insight 360 Formative Instruction System.
