We present a CYK and an Earley-style algorithm for parsing Range Concatenation Grammar (RCG), using the deductive parsing framework. The characteristic property of the Earley parser is that we use a technique of range boundary constraint propagation to compute the yields of non-terminals as late as possible. Experiments show that, compared to previous approaches, the constraint propagation help...

The main rivals to the input or comprehension hypothesis are the skill-building and comprehensible output hypotheses. Studies claiming to show that the skill-building hypothesis is correct consist of studies of the impact of grammar instruction and error correction. These studies show only that instruction and correction have a modest impact on tests in which subjects are focused on form. Compr...

Although a wide array of studies has sufficiently documented the use Flipped and Corpus learning methods in ELT context respectively, marrying both EFL grammar classes remains scanty. To fill this gap, collaborative action research (CAR) jointly designed implemented flipped classroom-based corpus instruction involving an English instructor to promote students’ grammatical knowledge their percep...

TOEFL iBT has turned recently heads to the impacts language tests can have on language learning. Since error analysis-based instruction has gained a new life with the advent of the computer analysis of the learner’s language, the researchers of this study embarked on examining a sample of integrated and independent writing tasks of 45 Iranian TOEFL iBT candidates in order to identify and classi...
