“…E-dictionaries maybe either online (e.g., the website Dictionary.reference.com), which can also be available apps for portable devices, and smart mobile phones, and can be efficiently used to facilitate reading comprehension and vocabulary acquisition for adult learners of a second/foreign language (Ji, 2009;Mekheimer, 2012;Shi, 2008;Welker, 2010;Zhang, 2000). The use of edictionaries in foreign language learning settings has been reported to facilitate reading comprehension and vocabulary enhancement (Knight, 1994;Koga, 1995;Mekheimer, 2012), often better than paper dictionaries (Koga, 1995;Laufer, 2001;Mekheimer, 2012). Chen (2011) investigated the effects of paper-based bilingual dictionaries versus online edictionaries and concluded that the use of the latter exponentially improved learning and retention of unknown words encountered during a reading, with e-dictionaries providing a comparatively stronger learning effect than paper dictionaries.…”
