Effects of CALL instruction on high-level, low-frequency English vocabulary Linguistics, CUNY Graduate Center Euna Cho Agenda • Background information on L2 vocabulary knowledge and learning • Methods and procedures of the study • Results and further research suggestions Introduction • Importance of vocabulary learning in L2 language learning, yet teaching is neglected due to the belief in vocabulary learning through extensive reading • Effectiveness in more form-focused, deliberate, intentional teaching in L2 vocabulary acquisition, especially for high-level, low-frequency words shown on the Graduate Record Examination (GRE) • Advantages of Computer-Assisted Language Learning (CALL) instruction in L2 vocabulary teaching Frequent word lists • General Service List (GSL) of English words: 1,964 word families (West, 1953), 80% coverage • New General Service List (NGSL): 2,368 word families (Browne, 2013), 90% coverage • Academic Word List (AWL): 570 word families outside the GSL (Coxhead, 2000) Required number of words • Approx. 3,000 words to engage in a daily conversation (Laufer & Nation, 2011) • 6,000-9,000 words to understand radio interviews or literature (Laufer & Nation, 2011) • 10,000 words to understand 95% of the general texts (Hazenberg & Hulstijn, 1996) • 17,000 words: receptive knowledge of collegeeducated native English speakers (Zechmeister et al., 1995) Frequency of encounters • A learner should see the same word more than 10 times (Laufer & Nation, 2011). • Each new experience with the word should take place before the word is forgotten (Laufer, 2006). • A learner should read 1-2 books per week, which will take 29 years to learn the most frequent 2,000 words (Zahar et al., 2001) Learning vocabulary through reading may not work. Academic words • Receptive knowledge of 17,000 words among collegeeducated native English speakers (Zechmeister et al., 1995) • Learners pursuing higher education should have vocabulary knowledge used in academic contexts. • Moderate use in academic settings; rare in general context (e.g., convoluted, gratuitous, vociferous) • Low-frequency of appearance (Coxhead, 2000) • Form-focused, deliberate, and intentional learning of vocabulary words Vocabulary should be taught! CALL learning environment • Vocabulary is one of the most prevalent applications in a CALL environment. • Multimedia applications: pictorial, audio-visual information in addition to traditional textual cues • Retention is easier and more effective when words are learned in multiple modes (Chun & Plass, 1996). • Multimedia cues yield promising outcomes in L2 vocabulary acquisition (Akbulut, 2007; Al-Seghayer, 2001; Chun & Plass, 1996; Yoshii & Flaitz, 2002) Rationale • Efficacy of computer-mediated multimedia aids shown on beginner and intermediate level vocabulary (Al-Seghayer, 2005; Chun & Plass, 1996; Mohsen & Balakumar, 2011; Yoshii & Flaitz, 2002) • Little attention paid to high-level infrequent words that are important for particular purposes • Advanced-level words are hard to learn, requiring special attention (e.g., multimedia aids) The present study • Efficacy of multimedia cues (video) on advancedlevel English vocabulary shown on the GRE • 15 Korean L1 students preparing for graduate study in the U.S. • Testing 40 unfamiliar words selected from the pre-test (60 items) • Pre-test Definition Treatment (video / text) Post-test 1 (immediate) Post-test 2 (7 days) Post-test 3 (2 weeks) Context of the study • 4 week intensive GRE lecture series in Seoul, South Korea (4 hours X 5 days) in July 2014 • Total enrollment: 27 (9 male, 18 female) recruited from an internet blog • Instruction focused on vocabulary, reading comprehension, and essay writing • Target number of vocabulary: 1,500 GRE words – Etymology, images, videos, and mnemonics Participants • 23 15 for final analysis (6 male and 9 female) • Age: 24-34 (Mean 28, SD 2.94) • Length of residence: 0-10 years (Mean 1.16, SD 2.56) • M-TELP listening (45): 28-42 (Mean 33.8, SD 4.63) • Pre-test results (40): 0-5 (Mean 1.2, SD 1.42) Pre-test (60) • 60 items tested by 24 students (outside 5,000 frequent words) • 40 items below 10% of correctness selected Final test items (40) Pre- and post-tests Treatment • Experimental group (video group) – Dictionary annotations (Korean/English) – Video clips with subtitles • Control group (text group) – Dictionary annotations (Korean/English) – Handout with scripts of the video clips Dictionary annotations Video clips • 40 video clips from movies or TV shows • Edited to show the gist (5-20 seconds) with subtitles • Repeated with synonyms or definition (e.g., pulchritude vs. beauty) • Visually represented with gestures and facial expressions • Played one time with a description or background information Are you and your friends gonna be over here all the time like partying and hanging out? Oh, don’t worry. I am not really a party girl. Wow, don’t just be blurting stuff out. I want you to really think about your answers. From: Friends As you can see, I don’t look like that. That was a moment of useful pulchritude that is long since past. Youthful pulchritude? Don’t ask me what pulchritude means. Pulchritude means beauty. From: Puccini for Beginners King, you’re majesty. I gravel at your feet. It’s not gravel, it’s grovel. From: Lion King Handout for text group Script for the instructor Results Limitations and further research • A small number of participants • Vocabulary size test • Vocabulary learning experience • Participants from diverse language background • More precisely-structured instruction (e.g., recorded instruction) References • Akbulut, Y.
