Many English language teachers are wrapped around teaching vocabulary from textbooks. However, students will learn English faster when given the opportunity to acquire vocabulary that will be meaningful to their personal lives. By taking an inventory of students' needs, you will know what vocabulary will best suit your class.
Beginning and intermediate students may need words that have to do with immediate life skills, such as going to the doctor, shopping for food, mailing a letter, cashing a check. Several excellent resources are available that aid in the teaching of this type of vocabulary. For instance, Pearson Longman offers Word by Word, a picture dictionary by Steven Molinsky and Bill Bliss. This book presents vocabulary on specific topics for adult learners.
For higher-level students, vocabulary needs may be for a specific job or career choice. Vocabulary lists can be found online that work quite effectively for this purpose. For instance, if you have students who want to obtain a degree in accounting, websites such as Yourdictionary.com and Investorwords.com are an excellent resource.
Topic specific words lists are an important resource for students. These word lists allow them the ability to search for a correct term in a place where they are likely to find what they need. In other words, they will not get frustrated by aimlessly searching a dictionary or encyclopedia. If they have a word list for a topic, they are more likely to find what they want.
