在第二语言习得的初始阶段，学生学习了几千个单词，主要是高频单词。然而，功能性语言能力需要掌握相当多的单词。因此，在语言习得的中级和高级阶段，有必要在短时间内学习大量词汇。没有足够的时间来复制自然的（主要是偶然的）L1单词习得过程。偶然习得这些词的可能性很小，因为它们出现的频率很低，在第二语言学习材料中并不经常出现。从真实的第二语言阅读文本中习得新词，通过语境推理等策略也不是一个解决方案，原因有很多。除了在相对较短的时间内有意识地学习大量新单词外，似乎没有其他选择。要学习的单词可以单独呈现，也可以在上下文中呈现。双语词汇表的呈现似乎是一个有吸引力的捷径，因为它比上下文呈现花费更少的时间，并产生良好的短期效果。然而，长期保留往往令人失望，因此上下文介绍似乎是可取的。任何建议如何在教学环境中实现这一点应该基于对L2单词学习问题的两个最重要方面的系统分析，即选择相关词汇（哪些和多少单词）和为习得过程创造最佳条件。本文阐述了描述一个计算机辅助词汇习得程序（CAVOCA），它试图做到这一点：该程序操作化当前的理论思想的词汇习得，其内容是基于一个系统的库存相关的目标群体的词汇。为了确定其效率，该计划进行了对比，在一些实验设置与配对的联营公司学习新单词的方法。实验结果表明，这两种方法相结合的方法是最可取的。
During the initial stages of instructed L2 acquisition students learn a couple thousand, mainly high frequency words. Functional language proficiency, however, requires mastery of a considerably larger number of words. It is therefore necessary at the intermediate and advanced stages of language acquisition to learn a large vocabulary in a short period of time. There is not enough time to copy the natural (largely incidental) L1 word acquisition process. Incidental acquisition of the words is only possible up to a point, because, on account of their low frequency, they do not occur often enough in the L2 learning material. Acquisition of new words from authentic L2 reading texts by means of strategies such as contextual deduction is also not a solution for a number of reasons. There appears to be no alternative to intentional learning of a great many new words in a relatively short period of time. The words to be learned may be presented in isolation or in context. Presentation in bilingual word lists seems an attractive shortcut because it takes less time than contextual presentation and yields excellent short term results. Long term retention, however, is often disappointing so contextual presentation seems advisable. Any suggestions how to implement this in pedagogic contexts should be based on a systematic analysis of the two most important aspects of the L2 word learning problem, that is to say, selecting the relevant vocabulary (which and how many words) and creating optimal conditions for the acquisition process. This article sets out to describe a computer assisted word acquisition programme (CAVOCA) which tries to do precisely this: the programme operationalises current theoretical thinking about word acquisition, and its contents are based on a systematic inventory of the vocabulary relevant for the target group. To establish its efficiency, the programme was contrasted in a number of experimental settings with a paired associates method of learning new words. The experimental results suggest that an approach combining the two methods is most advisable.
