Commercial vs Free E-resources for English Language Teachers
Barry Natusch 한국멀티미디어언어교육학회 2004 멀티미디어 언어교육 Vol.7 No.1
Natusch, Barry. (2004). Commercial vs Free E-resources for English Language Teachers. Multimedia-Assisted Language Learning, 7(1), xx∼xx. The issue of paid-for and free services in an information and communication context is receiving a lot of attention recently, particularly with the publicity surrounding notions of intellectual property and piracy. Definitions of commercial, shareware and freeware are discussed. A selection of commercial and free e-resources for teaching, administrating and researching useful for English teachers is presented and their respective strengths and weaknesses highlighted. The survey concludes by showing that trends emerging among commercial and free ELT resources suggest that while many mainstream applications are freely or cheaply obtainable, certain specialist items are still only available through commercial channels.
