This paper offers a theoretical approach to vocabulary instruction from the evidence provided by lexical errors as the main sources of difficulty in the EFL acquisition process, it reviews previous research and from it suggests new ways of dealing with lexical errors in the classroom. Some practical implications are concluded which rely on lexical…

Language acquisition is used for the process where a language is acquired as a result of natural and largely random exposure to language, whereas the term language learning refers to the exposure structured through language teaching. Children acquire language from 18 months to puberty. The child's grammar is semantically based. Children reflect…

We present a new feedback strategy implemented in a natural language generation-based e-learning system for German as a second language (L2). Although the system recognizes a large proportion of the grammar errors in learner-produced written sentences, its automatically generated feedback only addresses errors against rules that are relevant at…

This study argues that positive second-language (L2) data do not necessarily rule out inappropriate L2 grammar. Rather, L2 learners appear to postulate first-language (L1) grammar as an interim theory about the L2, at least in the initial stages of L2 acquisition. The case where L2 grammar intersects L1 concerning time adverbial clauses was chosen…
