Positive Evidence Versus Explicit Rule Presentation and Explicit Negative Feedback: A Computer‐Assisted Study

The facilitative role of explicit information in second Language acquisition has been supported by a significant body of research (Alanen, 1995; Carroll & Swain, 1993; de Graaff, 1997; DeKeyser, 1995; Ellis, 1993; Robinson, 1996, 1997), but counterevidence is also available (Rosa & O’Neill, 1999; VanPatten & Oikkenon, 1996). This experimental study investigates the effects of computer‐delivered, explicit information on the acquisition of Spanish word order by comparing four groups comprised of [+/−Explanation] and [+/−Explicit Feedback]. Results showed that all groups improved significantly and similarly on interpretation and production tests. It is suggested that explicit information may not necessarily facilitate second Language acquisition and that exposing learners to task‐essential practice is sufficient to promote acquisition.
