The oral approach / situational language teaching
The oral approach was developed from the 1930s to the 1960s by British applied linguists such as Harold Palmer and A.S. Hornsby. They were familiar with the Direct method as well as the work of 19th century applied linguists such as Otto Jesperson and Daniel Jones but attempted to formally develop a scientifically-founded approach to teaching English than was evidenced by the Direct Method.
A number of large-scale investigations about language learning and the increased emphasis on reading skills in the 1920s led to the notion of "vocabulary control". It was discovered that languages have a core basic vocabulary of about 2,000 words that occurred frequently in written texts, and it was assumed that mastery of these would greatly aid reading comprehension. Parallel to this was the notion of "grammar control", emphasizing the sentence patterns most-commonly found in spoken conversation. Such patterns were incorporated into dictionaries and handbooks for students. The principle difference between the oral approach and the direct method was that methods devised under this approach would have theoretical principles guiding the selection of content, gradation of difficulty of exercises and the presentation of such material and exercises. The main proposed benefit was that such theoretically-based organization of content would result in a less-confusing sequence of learning events with better contextualization of the vocabulary and grammatical patterns presented. Last but not least, all language points were to be presented in "situations". Emphasis on this point led to the approach's second name. Proponent claim that this approach leads to students' acquiring good habits to be repeated in their corresponding situations. Teaching methods stress PPP (presentation (introduction of new material in context), practice (a controlled practice phase) and production (activities designed for less-controlled practice)).
Although this approach is all but unknown among language teachers today, elements of it have had long lasting effects on language teaching, being the basis of many widely-used English as a Second/Foreign Language textbooks as late as the 1980s and elements of it still appear in current texts. Many of the structural elements of this approach were called into question in the 1960s, causing modifications of this method that lead to Communicative language teaching. However, its emphasis on oral practice, grammar and sentence patterns still finds widespread support among language teachers and remains popular in countries where foreign language syllabuses are still heavily based on grammar.
Directed practice
Directed practice has students repeat phrases. This method is used by U.S. diplomatic courses. It can quickly provide a phrasebook-type knowledge of the language. Within these limits, the student's usage is accurate and precise. However the student's choice of what to say is not flexible.
