5 Vocabulary Size How large a vocabulary size do you need to function in English? It Depends!
6 Vocabulary Size (Word families) Daily conversation 2, ,000 (minimum size which enables basic communication) 5, ,000 (size which enables conversation on a wide range of topics) Read authentic texts 3, ,000 (begin to read a range of authentic texts 8, ,000 (size which enables reading on a wide range of topics)
High / Low frequency Vocabulary Hi-frequency Everything else = Low-frequency vocabulary? vocabulary TEACHDISREGARD 2,000 word families everything else
High / Mid / Low frequency Vocabulary 3,000 3,000 – 9,000 9,000+ Hi-frequency Mid-frequency Low-frequency vocabulary vocabulary vocabulary TEACHADDRESS IN SOME WAY STRATEGIES
10 Where do these size requirement estimates come from anyway?
11 Fat City (95% coverage) In December, to the delight of many __________ and the ______ of many doughnut lovers, the New York City Board of Health voted to ban artificial trans fats from restaurants, school cafeterias, pushcarts, and almost every other food-service establishment it oversees, which includes most everything except hospitals. Trans fats dont occur naturally in the things people like but feel guilty eating, or at least not at high levels (there are small proportions in the fat in meat and dairy products). But artificial ones are plentiful in commercial foods, because they are easy to use, cheaper than natural fats, and keep practically forever. Trans fats are made by pumping _______ gas into liquid fats usually in the presence of _____ so that they will remain solid at room temperature, like butter and ___; and they have the same wonderful properties in pie crusts, cookies, and cakes. Crisco, still _____ for solid shortening made by partial ___________ (of cottonseed oil), soon became the ______ choice for pie crust and fried chicken, making pastry almost as flaky and skin almost as crisp as ___ does.

Trans fats dont occur naturally in the things people like but feel guilty eating, or at least not at high levels (there are small proportions in the fat in meat and dairy products). But artificial ones are plentiful in commercial foods, because they are easy to use, cheaper than natural fats, and keep practically forever. Trans fats are made by pumping hydrogen gas into liquid fats usually in the presence of nickel so that they will remain solid at room temperature, like butter and lard; and they have the same wonderful properties in pie crusts, cookies, and cakes. Crisco, still generic for solid shortening made by partial hydrogenation (of cottonseed oil), soon became the sanitary choice for pie crust and fried chicken, making pastry almost as flaky and skin almost as crisp as lard does.
13 The Truth About Beauty (98% coverage) Cosmetics makers have always sold hope in a jar – creams and ______ that promise youth, beauty, sex appeal, and even love for the women who use them. Over the last few years, the marketers at Dove have added some new-and-improved __________. Theyre now promising self-esteem and cultural transformation. Doves Campaign for Real Beauty, declares a press release, is a global effort that is intended to serve as a starting point for societal change and act as a ______ for widening the definition and discussion of beauty. Along with its thigh-firming creams, self-tanners, and hair conditioners, Dove is peddling the crowd-pleasing notions that beauty is a media creation, that recognizing plural forms of beauty is the same as declaring every woman beautiful, and that self-esteem means ignoring imperfections.
14 The Truth About Beauty (98% coverage) Cosmetics makers have always sold hope in a jar – creams and potions that promise youth, beauty, sex appeal, and even love for the women who use them. Over the last few years, the marketers at Dove have added some new-and-improved enticements. Theyre now promising self-esteem and cultural transformation. Doves Campaign for Real Beauty, declares a press release, is a global effort that is intended to serve as a starting point for societal change and act as a catalyst for widening the definition and discussion of beauty. Along with its thigh-firming creams, self-tanners, and hair conditioners, Dove is peddling the crowd-pleasing notions that beauty is a media creation, that recognizing plural forms of beauty is the same as declaring every woman beautiful, and that self-esteem means ignoring imperfections.

20 How to Address Such Large Amounts of Vocabulary? Why not teach just the most content-ful words? Technical Vocabulary ESP vocabulary Academic Support Vocabulary e.g. Academic Word List (Coxhead, 2000)
Developing LSP Word Lists Technical vocabulary is dependent for a full appreciation of its meaning on the meaning of the other terms in the cluster of which it is a member. (Godman and Payne, 1981: 37, in Coxhead and Nation, 2001)
An ESP Text (Wang, et al., 2008) Technical Vocabulary only wounds wound healing. wounds wounds pressure ulcers leg ulcers. wounds clinical Pressure ulcers ischemia necrosis hospitalized mobility Leg ulcers etiologies. ulcers dysfunction backflow blood. blood macromolecules dermis, nutrients
A Complete Medical Text Chronic wounds represent a different kind of challenge for wound healing. These wounds do not usually involve a large surface area, but they have a high incidence in the general population and thus have enormous medical and economic impacts. The most common chronic wounds include pressure ulcers and leg ulcers. In the United States alone, these wounds are estimated to affect more than 2 million people with total clinical treatment costs as high as $1 billion annually. Pressure ulcers, characterized by tissue ischemia and necrosis, are common among patients in long-term care settings, but patients hospitalized for short-term care settings are also at risk if mobility is impaired. Leg ulcers can have a variety of etiologies. Venous ulcers are the most common, often resulting from dysfunction of valves in veins of the lower leg that normally prevent the backflow of venous blood. Venous congestion leads to leakage of blood and macromolecules into the dermis, which can act as physical barriers to diffusion of oxygen and nutrients from the
Need Foundation Vocabulary So academic and technical word lists are useful, but cannot replace the need for learners to have a solid foundation of high- and mid-frequency vocabulary in place
26 How to Address Such Large Amounts of Vocabulary? These are clearly large numbers of word families to learn Long-term goal Most teachers do not have the time, expertise, or opportunity to organize large amounts of vocabulary over a period of time Most will rely on textbooks to provide the principled selection and instruction of vocabulary
27 How to Address Such Large Amounts of Vocabulary? A single textbook cannot do the job (even a vocabulary textbook) So are textbook series up to the task?
29 Chilean Case Study (Diaz Berrocal) Ministry sets vocabulary targets for 8 years of ELT schooling Analyzed mandatory books for the 8 years ( 5 th -12 th grades) Counted number of word families in books Frequency analysis of those word families How much recycling was there?

37 Chilean Case Study Conclusions Textbooks do not match Ministry goals No obvious approach to vocabulary selection or recycling Ministry gives size goals, not specific word lists Publishers given no guidance as to what words to use Different publishers do not liaise with each other to build coherent program
Vocabulary Knowledge is a Complex Construct word meaningpronunciationgrammarfrequencyconnotationformalitycollocationsassociationsspelling
39 What Does It Mean to Know A Word? FormSpoken form Written form Word parts MeaningForm and meaning Concept and referents Associations UseGrammatical functions Collocations Constraints on use (register, frequency…) (Nation, 2001: 27)
40 Lexical Organization Vocabulary size is not a feature of individual words: rather it is a characteristic of the test takers entire vocabulary. (Meara and Wolter, 2004: 87) Size is a feature of the overall lexicon
41 Lexical Organization Nature of the Lexicon must be connected with vocabulary knowledge Better connected and more highly organized lexicons should relate to more vocabulary knowledge
42 Automaticity Should also lead to faster speed of access and use Fluency
43 How to Facilitate this Complex Learning for Large Numbers of Words? Incidental Learning Explicit Intentional Learning
44 Incidental Learning Many practitioners believe that all necessary vocabulary can be learned incidentally simply by being exposed to, and by using, language
45 Incidental learning does occur in L2 (Reading) Do Things Fall Apart? (Pellicer-Sánchez and Schmitt, 2010) Nigerian language Ibo Spelling recognition: (2-4)=16%(10-17)= 85% Word class recall: (2-4)=7% (10-17)= 54% Meaning recognition: (2-4)=33%(10-17)= 80% Meaning recall: (2-4)=5%(10-17)= 48%
46 Incidental learning does occur in L2 (Listening) (Van Zeeland & Schmitt, 2013)
47 Problem: Incidental learning is limited by amount of exposure It takes at least 8-10 reading exposures to develop an initial form-meaning link and more for meaning recall knowledge (even more for listening) Other word knowledge types (e.g. collocation, register, derivative forms) will likely take many more exposures Most L2 learners do not read enough to ensure this number of repetitions (Cobb, 2007) SO incidental learning is useful, but not sufficient
48 Intentional learning Virtually all research shows that intentional learning with an explicit focus on the target linguistic features results in learning that is –Stronger –More durable –More consistent among learners Productive mastery seems to come mainly from productive engagement
49 Is Knowledge of the Form-Meaning Link Enough? Learning a word might require more than just learning its meaning and form For receptive use, perhaps a meaning-recall level of mastery might suffice See/hear word form and retrieve/recall meaning All of the other contextual word knowledge aspects are already in the discourse/text
50 Various Kinds of Word Knowledge are Learned Differently But for productive use, learners have a concept in their head, but must produce the appropriate lexical form This requires most (all?) of the contextual kinds of word knowledge These contextual aspects (e.g. collocation, connotation, register constraints) are more difficult to teach, and probably require large amounts of exposure to acquire incidentally
51 Different Types of Exposure and Learning Explicit Intentional Learning Can focus on most useful (frequent) words Stronger learning Mainly useful for teachable word knowledge aspects like form-meaning, word class, affixes Hard to cover enough words Hard to build in enough recycling
52 Different Types of Exposure and Learning Incidental Learning Get exposure to a wide variety of words A way to get more recycling Provides context for learning contextual types of word knowledge Incidental learning is useful, but the uptake is slow and inconsistent
53 Different Types of Exposure and Learning Intentional and incidental learning are complementary They add different things to vocabulary knowledge They need to be combined in any principled vocabulary program
54 Formulaic Language All of my discussion up until now discusses single words, lemmas, or families There is a large amount of lexical patterning in language Formulaic language needs to be brought into the discussion of vocabulary use, acquisition, and pedagogy
What is Formulaic Language? Recurrent multi-word lexical items that have a single meaning or function (Schmitt, 2010) It is a umbrella cover term for a number of formulaic categories –Idioms –Collocations –Phrasal verbs –Lexical bundles –Lexical phrases –Phrasal expressions –etc
Learner Use of Formulaic Language Learners dont use many idioms Learners do use many high-frequency collocations (nice day) Learners dont use many lower-frequency but tightly-bound collocations (preconceived notions)
Learner Use of Formulaic Language But learners often do not use the collocations that they know very appropriately Inappropriate collocations is a leading problem in learner language Learners often use words with their correct meanings, but do not understand the correct context of use (collocation, register, frequency)
Learner Use of Formulaic Language Learners consistently overestimate their comprehension of reading texts that contain formulaic sequences that they either fail to identify or misunderstand, even at high levels of proficiency (Martinez and Murphy, 2011)
Learner Acquisition of Formulaic Language Boers & Lindstromberg (ARAL 2012) reviewed acquisition research: –Learning from exposure requires repetition (frequency) –Intentional learning produced better results –Raising awareness of formulaic language is not a powerful accelerator of learning –Knowing the component words makes learning a formulaic sequence easier –Providing learning strategies (dictionaries, concordance lines) produced mixed results
Pedagogical Implications Meunier review (ARAL, 2012) If formulaic sequences are so important: They need to be included in teaching syllabuses and materials We cant assume they will just be learned from exposure They need to incorporated into language tests to a greater extent
Pedagogical Implications But what formulaic sequences? In order to incorporate formulaic sequences into their teaching and testing, most practitioners need a list of formulaic sequences to address But what criteria to use?
Formulaic Framework (Martinez, 2013) Infrequent Frequent take credit take issue take time take place ,556 (per 100 million – BNC) Transparent Opaque take credit take time take issue take place
