Vocabulary learning strategies (VLS) is a method to help learners to understand and memorize the vocabulary. Vocabulary learning strategies are a series of specific actions used by learners to acquire, store, and retrieve information so as to enhance their progress in vocabulary learning (Oxford, 1990; Schmitt, 1997).

In the second language (L2) reading process, either vocabulary knowledge or content knowledge plays a critical role in reading performances (Yeh, 2009). Similarly, Laufer (1986) argued that vocabulary adequacy and accuracy matter more than grammatical correctness in order to convey a message with relative ease and comprehensibility. These two researchers indicated the importance of vocabulary knowledge – if you have a large vocabulary size, you could be better on reading comprehension and easy to convey a message. Yeh(2004) pointed that the subjects’ vocabulary sizes and their reading performances on the SAET(Scholastic Aptitude English Test) test had a positive and significant correlation. Furthermore, the way to promote the vocabulary size effectively is decided on the helpful vocabulary learning strategies. Cheng (2006), for example, stated that junior high school EFL
