Learning to improve grammar instruction through comprehensive analysis of past research

Abstract

AbstractHolistic study of grammar instruction is needed not only to establish the effectiveness of pedagogical techniques, but to determine when, and in what way, they should be utilized. Within a meta-analysis of 33 experimental studies, external stimuli impacting the language learner (scope of instruction, input or output enhancement, frequency of treatment, and EFL/ESL context) were concomitantly considered alongside cognitive factors (grammatical complexity and language proficiency). Results of linear regression revealed that the selected causal factors collectively explain more than 40 % of variability in the effectiveness of pedagogical techniques for English grammar production. Study further suggests that grammar emphasis with a limited scope may be more effective; input enhancement may be more effective with grammatical features that are less essential for communication (redundant, systematic, and less salient features such as past -
