Abstract: For English as a Second Language (ESL) students, vocabulary learning<br />

is at <strong>the</strong> core <strong>of</strong> language learning and use. This implies that lexical errors and<br />

insufficient vocabulary size among L2 learners prevent effective communication<br />

(Gass & Selinker, 2008). Currently, <strong>the</strong> scarcity <strong>of</strong> systematic, intentional<br />

vocabulary teaching in ESL classroom, in particular, unpromising outcomes from<br />

widely spread pedagogy, usage <strong>of</strong> written context or extensive reading, call for<br />

new L2 vocabulary teaching methods. This highlights major pedagogical issues<br />

such as how ‘receptive vocabulary’ is transferred to ‘expressive vocabulary’ for<br />

writing and speaking. The tools designed here, Visual Vocabulary Map (VVM),<br />

supports ESL learners’ strategy development for learning, using, and producing <strong>the</strong><br />

words. This concept mapping based visual representation tool (VVM) would<br />

possibly bring <strong>the</strong> benefits <strong>of</strong> organizing information through visual aids showing<br />

<strong>the</strong> relationships among words, this paper argues how <strong>the</strong> tools can promote<br />

learning and increasing vocabulary size.<br />

Introduction<br />

One <strong>of</strong> <strong>the</strong> most common ways <strong>of</strong> teaching vocabulary is using written context or extensive reading to<br />

learn word definitions (Feldman & Kinsella, 2005) in ESL classrooms. However, a number <strong>of</strong> research<br />

studies indicate that <strong>the</strong> implicit approach is held up as problematic for L2 learning due to several<br />

reasons. First, it requires significant amounts <strong>of</strong> contextual guessing which unfortunately results in low<br />

rate <strong>of</strong> vocabulary acquisition (Beck et al. 2002; Nagy, Herman, & Anderson, 1985). Second, incidental<br />

vocabulary learning through reading leads to only a superficial understanding <strong>of</strong> many vocabulary words<br />

(Paribakht & Wesche, 1997). Third, due to sparse exposure over modest periods <strong>of</strong> time, implicitly<br />

acquired vocabulary is <strong>of</strong>ten available to <strong>the</strong> learner only via receptive channels (Wesche & Paribakht,<br />

2000).<br />

Therefore, this paper proposes <strong>the</strong> specific design <strong>of</strong> computer assisted concept mapping tool that would<br />

work as conduits <strong>of</strong> amplifying <strong>the</strong> process <strong>of</strong> transferring receptive vocabulary into expressive vocabulary<br />

based on <strong>the</strong> cognitive <strong>the</strong>ory <strong>of</strong> multimedia learning (Mayer, 2005), mental model <strong>the</strong>ory (Schwartz &<br />

Black, 1996) and situated cognition (Brown, Collins & Duguid, 1989).<br />

Visual Vocabulary Map (VVM) is an interactive word concept map for L2 vocabulary learning in which a<br />

user creates vocabulary maps that blossom with meanings and branch to related words. Its innovative<br />

visual display promotes each student’s independent word learning process in and out <strong>of</strong> <strong>the</strong> classroom<br />

environment. Findings from incidental vocabulary learning which leads to a superficial understanding <strong>of</strong><br />

vocabulary words, VVM was developed to address <strong>the</strong> urgent needs <strong>of</strong> targeted instruction for vocabulary<br />

learning (Paribakht & Wesche, 1997).<br />

Designing Theory<br />

Concept mapping is a strategy that helps learners organize information through visual aids by showing<br />

<strong>the</strong> relationships among concepts. In designing VVM, cognitive <strong>the</strong>ory <strong>of</strong> multimedia learning (Mayer,<br />

2005), mental model <strong>the</strong>ory (Schwartz & Black, 1996) and situated cognition (Brown, Collins & Duguid,<br />

1989) are conceptually framed to enhance vocabulary learning and retention. When a learner is<br />

processing information through a concept map, it stimulates learners’ meta-cognitive awareness, assists<br />

appropriate monitoring strategy and increases <strong>the</strong> use <strong>of</strong> retrieving and memorizing knowledge (Liu, Chen<br />
