Research in second language acquisition reveals that adults have difficulty
learning the grammatical aspects of a foreign language. The present study investigated
the efficacy of three teaching methods that were predicted to help adults better learn the
grammar of a foreign language. First, lessons were presented in small pieces that
gradually increased to full sentences. Second, lesson trials were blocked such that
multiple examples of sentences with the same object or verb were presented
consecutively. Third, participants were instructed to gesture the actions of the verbs
within sentences. All three methods were predicted to increase the likelihood of learning
the grammar form of sentences through guiding adults’ attention to fewer components of language input at a time. In Experiment 1, 82 English native speakers played an
adventure videogame designed for the learning of French vocabulary and grammar of
French sentences for two one-hour sessions. All three methods were incorporated in the lessons portion of the game resulting in a 2(incremental vs. full sentence) X 2(blocked vs. unblocked order) X 2(gesture vs. no gesture) between subjects design. The results from Experiment 1 revealed a) more nouns were acquired than verbs and b) a trend that the incremental conditions performed worse than the full sentence conditions on the grammar measures. In Experiment 2, 110 adult learners played the French videogame, but only the blocked presentation and gesture imitation methods were incorporated in the lessons portion (omitting the method of incremental presentation). The results from Experiment 2 revealed a) conditions with either method of blocked presentation or gesturing performed better on vocabulary and grammar measures than the unblocked non-gesture condition, and b) the combination of blocked presentation and gesturing led to better learning of inductive grammar than either method alone. The outcome of the study suggests gesturing and blocked order teaching methods that encourage adults to attend to a few but important components within a sentence are advantageous in learning the grammar of a foreign language.

This study tests Newports Less is More hypothesis with a language teaching experiment. Computerized French language lessons were presented to forty-two adults over two one-hour sessions. Learning trials were presented either in full sentences to resemble the adult learning environment, or in small increments that gradually increased to full sentences, resembling the steadily expanding processing capabilities of children. Trials were also presented randomly or ordered such that multiple examples of the same objects and verbs were presented consecutively. Language proficiency tests were administered after the lessons. A 2 (Presentation: incremental or full sentence) x 2 (Order of presentation: blocked or random) mixed ANOVA was used to analyze the data. The incremental conditions outperformed the sentence conditions on all proficiency measures. There was no significant effect of the blocking manipulation. This outcome suggests that a teaching method based on Newport's Less is More hypothesis can be advantageous in learning a foreign language.
