There are several reasons DynEd has chosen not to require students to be on-line to study. First, high-quality, reliable, affordable broadband Internet is still not accessible in many parts of the world. Requiring students to be tethered while studying can be frustrating and distracting in an increasingly mobile world. Second, when rich multimedia content resides locally as DynEd’s does - on a LAN, lap-top, tablet or smart phone - interactive responses are guaranteed to be fast and smooth, even with full-motion video and high-end speech recognition exercises. Not being worried about, slowed down, or interrupted by connectivity issues allows students to concentrate on studying English, not on technology.
