Abstract
This report investigated the sensible impact of verbal, visual and a combination of verbal-visual techniques on vocabulary enhancement of Iranian high school students in Sirvan (Iran). The subjects were 60 male native speakers of Persian and Kurdish in intermediate level of L2 proficiency ranging in age from 15 to17. In order to have homogeneous groups, the students last year scores were look at between the three groups of 12-17, there part. In order to state the reliability of this test, the split –half method was utilized .The second one was question elicited demographic information such as names, age and job of father. They were selected from among seven classes and divided into three groups of 20, namely group 1, 2 and 3.The classes were held two days in a week, each day one hour, in Winter, 2014. The lexical items were taught to experimental groups by verbal (synonymy and exemplification), visual (pictures, flashcards, blackboard drawings and photographs) and verbal-visual techniques respectively. Put another way, group1 was treated by using visual aids (pictures, photographs, and flash cards), groups 2 was treated by verbal techniques (synonyms and exemplification). For this group no aids were used, but rather they used exemplification and synonyms, group2 was treated by using visual aids (pictures, photographs, and flash cards). For group 3, verbal and visual techniques were used complementary to convey meaning of the lexis. During the ten sessions of the treatment, 70 vocabularies were instructed to the three groups, Results of one way ANOVA showed that when verbal or visual techniques were used alone, verbal techniques manifested more vocabulary acquisition than visual modality and among three techniques employed in this study, complementary use of verbal-visual techniques was the most effective. It may be concluded that in directing the learners toward the ability of vocabulary skill, teachers should not solely rely on verbal cues and can benefit to a large extent from non-verbal aids. Results obtained from this study may have pedagogical implications in the areas of syllabus design and teaching methodology.

Introduction
1.1.Introduction
In reality, vocabulary is a vital part of language that students need to master in order to communicate effectively. Moreover, it is considered the base for the other skills. The ability to grasp the meaning of new words is a vital skill to strengthenreading and listening comprehension. This can positively impact overall academic success and can develop skills for real world applications. This calls for more attention to thisimportant skill, i.e., vocabulary.
Researchers have seen that students face serious problems regarding this aspect of language (vocabulary learning). Learners tend throughout learning stages to favor interesting methods which make interacting, exciting and fun learning. This motivated me to conduct the present study which aimed to investigate the effectiveness of visual and verbal techniques on vocabulary on vocabulary achievement.
Laraba (2007:136) states that “foreign language vocabulary learning is determined by the similarities that may exist, at different levels, between the first language and the second or foreign language learnt. Nation (1990: 31) suggests the following list of the different kinds of knowledge that a person must master in order to know a word:
1. The meaning(s) of the word
2. The written form of the word
3. The spoken form of the word
4. The grammatical behavioral of the word
5. The collocations of the word
6. The register of the word
7. The associations of the word
8.The frequency of the word
English has become the language of international business, diplomacy and professions. After all, it is the language of the United Nations. English has become the most dominate language in the world. As time passes, more people are learning English. Nowadays, the whole world seems to speak English. As David (2009) asserts, it is the language of travel, tourism, science and technology. It became a universal language that covered all aspect of life, where people of different nationalities used it to communicate with each other and it became the language of science, technology, politics, economy and education. This universal acknowledgment of English as the language of today and the need for good communication skill in English has created a huge demand for teaching English around the world. This has put a tremendous pressure on scholars to cope with this demand and to contribute to the development of a new and different teaching methodology for teaching English as a foreign language Hamdona(2007:1). Educators know that words and vocabulary strongly impact learners’ lives. In fact, educated individuals are often identified by their written and spoken vocabularies (Blachowicz& Fisher, 2004). Beck, McKeown and Kucan (2002) in their book, Bringing Words to Life: Robust Vocabulary Instruction, introduce the first chapter with a reminder that vocabulary plays a “critical role…in people’s lives and future possibilities. A large vocabulary repertoire facilitates becoming an educated person to the extent that vocabulary knowledge is strongly related to reading proficiency” (p. 1). In order to be aware of the full importance vocabulary plays in the lives of adolescents, it is necessary to first have a comprehensive definition of vocabulary. According to Lehr, Osborn, and Hiebert (2004), vocabulary is knowledge of words and their meanings. For vocabulary and word knowledge, Cronbach (1942) describes several qualitative dimensions, defined as the kind of knowledge one has about a word and the uses to which that knowledge can be put:
Generalization: The ability to define a word.
Application: The ability to select or recognize situations appropriate to a word.
Breadth: Knowledge of multiple meanings.
Precision: The ability to apply a term correctly to all situations and to recognize appropriate use.
