Annotation: This article is dedicated to teaching vocabulary memorization to non-standard learners. In this article we will explore the main causes behind the need for vocabulary memorization techniques for non-standard learners. The aim of this article is to investigate the usage and assessment of vocabulary memorization strategies as a second language to non-standard students. INTRODUCTION In our cutting-edge of era, more and more students with different cultural and linguistic backgrounds have been required to learn English as a second language in addition to their first language to integrate themselves into English schools and additionally in English society. When teaching students a foreign language, every teacher pays more attention to vocabulary than grammar. As long as everyone communicate through words wherever and whenever due to exchange ideas with people in certain fields. It is a fact that teaching vocabulary memorization to any English learners is important, because by teaching vocabulary memorization, language learners can expand their word bank, enabling them to improve their speaking and writing abilities. This can lead to better communication and more successful interactions in various contexts, such as school, work, and daily life. The definition of vocabulary is that all the words known and used by a particular person do not constitute all the words a person is exposed to. The learning of vocabulary within a relevant cultural context is a much enlightening and interesting experience for the student than learning vocabulary in isolation. The aims of this research are to highlight the memorization strategies that teachers usually adopt to teach vocabulary to non-standard learners. It also attempts to identify from a number of memorization strategies, according to some scientists' typology, the most appropriate ones for teaching vocabulary according to teachers' opinions. MAIN PART English has become the most important foreign language in the world. At present, English is the language for international communication such as; science, health, economic, commerce, advertising, diplomacy and transmitting advanced technology. Some scholars express that in the age of globalism we live nowadays, the interdependence of nations and countries creates a need for a global language and no language qualifies for this better than English. Speaking is the most essential part in human communication. We need ability to speak each other to share our ideas, feeling, thoughts, and opinion, to give information and message to others. It is a means through which learners can communicate with others to achieve certain goals or to express their opinions, intentions, hopes and viewpoints. Vocabulary learning plays a crucial role in this effort. However, for years the importance of teaching vocabulary was underestimated, while too much emphasis was placed mainly on grammar. According to Wilkins, we can convey very little without grammar, but we cannot convey anything without vocabulary. We know that no matter how good our knowledge on grammar is, if our vocabulary is poor, we cannot completely reveal our language skills such as speaking, reading, writing and also listening. Teaching language cannot be separated with teaching vocabulary. Vocabulary is considered as an important component in English language teaching. Furthermore, five categories of vocabulary, such as ESP, active/productive, passive/receptive, function/structure and content vocabulary have to be distinguished in teaching vocabulary. ESP vocabulary helps the learners to enlarge their use of the content words. This vocabulary is learned in the classroom situation that students have to learn the forms and to understand the concepts behind the words away from a real situation. In everyday speech we utilize active (or productive) vocabulary that is learned for performance in any communication act. Teachers should teach active vocabulary through focusing on the pronunciation, correct form, appropriate collocation and meaning so that learners can easily remember them. Among these categories passive vocabulary has not significant side for production in speaking and writing. This category is meant for recognition and understanding that it is needed for comprehension. Teachers do not ask to use it in everyday speech but recognize it when occurring in context. Function vocabulary is the part of the grammatical system of the language since its main function is grammatical. This category is limited in number unlike content vocabulary. Content words are open-ended in the sense that new nouns, verbs, adjectives and adverbs are often coined to name new things or processes which are closely related to one's experience.
