Becoming a Good Teacher

I recently updated my book, Teach and Leorn: Reflections on Communicative Language Teaching, from which this is a chapter, and made it available on Kindle and as an inexpensive book. To enjoy a read, please click here.

What are the qualities of great teachers? According to Jeremy Harmer, good teachers are attentive, understanding, good listeners, passionate. They give interesting classes. They bring their personalities and life experience into the classroom, and develop common ground with their students. They are flexible, student-centred, professional and knowledgeable, empathetic and motivating. They know their students’ names.

There is more. Good teachers adjust their language to a level students can understand without sounding unnatural or patronizing (this is called “modified input”.) They also use gestures, expressions and mime to communicate (this is called “comprehensible input”.)

The qualities students want in a teacher vary from culture to culture. For example, a TEFL student recently undertook a survey of Thai students in a TEFL class. What do Thai students want in a teacher? First, they want a teacher who is kind. They also want a teacher who understands the subject and is prepared for class. They want a teacher who is “human”, by which they explained that he should not be egotistical. And they want a teacher who arrives in class on time. These ideas are largely consistent with Harmers, but you can see cultural differences brought on by the insistence on kindness, humanity and being on time. (Thais are more frequently late than in the West.)

Here are some other ideas about the teacher’s roles and responsibilities. According to one writer, “great teaching comes from preparing thoroughly, challenging the students, listening carefully and respectfully, constantly learning as you teach, and including in every class a clear, insightful, new concept.” According to another, “the teacher’s main responsibilities are to choose class materials and to set class standards.” And according to a third, teaching and learning are part of the human condition. “We are all here to teach and learn.”

So those are the qualities of the good teacher. And there are as many ways to be a good teacher as there are teachers who are determined to do a good job. However, one choice that does seem to go a long way toward helping the teacher become a better teacher is the decision to use inductive methods. Here is a brief explanation of how that works, with examples.

Inductive and Deductive Teaching:
Let’s start with the basics. English language teaching consists of applying four linguistic skills (listening, speaking, reading and writing) to three groups of language items (structural, lexical and phonological). The latter correspond roughly to grammar, vocabulary and pronunciation; they amount to linguistic content.

There is endless discussion among teachers about the relative merits of “inductive teaching” compared to “deductive teaching.” In inductive teaching, the students practice language forms, but discover rules or generalizations on their own. They induce the rules from the examples they have practiced. In inductive presentation, the teacher makes the rules explicit by asking students to provide the answer. In deductive teaching, the teacher first gives the students the rules for a language form. Then they practice using them.

Here are examples of each.

Inductive Teaching
1.Write the following sentence on the board (or give it to them as a handout): “She gave me a beautiful big old brown Chinese hat.”
2.Then give them additional sentences, and ask them to put the adjectives in the right order. Example: “I want to buy a ____ ____ ____ ____ ____motorcycle.” (Japanese, red, pretty, new, small).
3.Make the scrambled adjectives increasingly more challenging in the worksheet sentences. Thus, they have to think a bit harder with each new sentence. In this way they will figure out for themselves (induce) how to place adjectives.
4.Elicit ideas from the students about the correct order of adjectives. Using that input, write the rule on the board.

Deductive Teaching:
1. Give the students the following information in a handout:
In English, adjectives come before a noun in a particular order. The order of adjectives is the following:
A. First comes opinion: (Lovely)
B. Then we provide physical description, in a certain order:
1. Size (big)
2. Age (old)
3. Condition (faded)
4. Colour (red)
5. Shape (elongated)
6. Sex (N/A)
C. Then origin: (Canadian)
D. Then material: (birch bark)
E. Then purpose: (racing)
F. And the noun brings up the rear: canoe
2. Give them some adjectives and ask them to write sentences using three or more adjectives in the right order. Their job is to "deduce" the right answers from the rule you set out at the beginning.
3. Check the sentences to see whether they got them right.

These two forms of teaching practice are quite different. In general, use inductive teaching. This may require putting more work into your lesson plans, but it is worth it.

Up from the Bottom or Down from the Top?


I recently updated my book, Teach and Learn: Reflections on Communicative Language Teaching, and made it available on Kindle and as an inexpensive paperback. To enjoy a read, please click here.


By Peter McKenzie-Brown

Psychology long ago began to debate two views – “top-down interpretation” and “bottom-up processing”– of how we understand language. Although the evidence is ambiguous, researchers generally believe they are distinct but complementary processes. For language instructors, the debate is less important than an appreciation of the roles these parallel processes play in classroom teaching and learning.

This discussion argues that good teaching practice accepts both views of language learning. However, their relative importance largely depends on the skills of the language learner.

To appreciate this, let’s begin with points of view. The advocates of “top-down interpretation” argue that background knowledge and previous experience of a situation, context, and topic play primary roles in helping us interpret meaning. We use prior knowledge and experience to anticipate, predict, and infer meaning. By contrast, the advocates of “bottom-up processing” believe language relies more heavily on decoding the sounds and letters of a language into words, clauses, sentences, and such. We then use our knowledge of grammatical, syntactic and lexical rules to interpret meaning. In this view, language users work from the bottom – the sounds they hear and the letters they encounter – to identify meaning.

To put that broad debate into context, consider that the primary focus of communicative language teaching is to develop communicative competence. CL teachers develop this competence through the use of materials and activities that focus on using language functions – for example, describing people and telling time. Because native-speakers use higher mental schema when they are processing language, language teachers develop activities that will enable their second-language learners to do the same. Broadly speaking, activities of these kinds involve top-down learning skills.

Is this always a good thing? No. Some language teachers are too quick to jump on the top-down bandwagon. In our view, better teachers are those who strike a conscious balance between top-down and bottom-up learning, which both have roles in language instruction.

According to Robert Norris, who uses listening activities to illustrate, “If we…require (our) students to use native speaker processing skills without first giving (them) a firm grounding in decoding the stream of sounds they hear, we run the risk of causing (them) more frustration and confusion than they can handle.”

We will return to Norris’s thoughtful discussion shortly. In the meantime, remember that bottom-up processing is particularly important when learners use the receptive language skills of listening and reading, because it plays a big role in making input comprehensible. And comprehensible input is the engine of effective language acquisition.

Bottom-up…: The bottom-up view assumes that listening is a process of decoding sounds and graphemes (the letters of the alphabet). We start with the smallest units, and gradually decode them until we understand the content of what we are listening to or reading.

The number of micro-skills involved is large. For example, when we listen we discriminate among the distinctive sounds of English, recognize stress patterns and the rhythmic structure of English, and discern how we use stress and intonation to signal information. Also, we need to identify words in stressed and unstressed positions and in reduced forms. We also have to recognize grammatical structures and typical word-order patterns. Meaning and comprehension are the last steps in the decoding process.

When we read, we use the building blocks of language to make meaning of what we see on the printed page. Bottom-up processes include sounds and graphemes -- the representation of sounds by letters. In English this involves word recognition for the countless irregular spellings and a sophisticated system of punctuation. We then need to to process written information through grammar and sentences. From these blocks we build comprehension.

…and Top-down: By contrast, top-down proponents believe that language processing involves the reconstruction of meaning through prior knowledge or “schema.”

Listeners actively reconstruct the original meaning of the speaker using incoming sounds and other signals like body language as clues. Prior knowledge of context and situation enables us to make sense of what we hear. A native speaker, for example, may completely zone out while hearing the news, then snatch a few brief cues that quickly draw him in. Similarly, when we begin a phone conversation to make an appointment, we shift into formal speech-patterns for such situations. This is another instance of schema guiding language use.

We also use schema to help us understand what we are reading. For example, the format of letters, emails and magazine ads are similar from culture to culture. Their format, whether in the reader’s first or second language, provides specific and useful information about what we can be likely to expect. Other top-down skills include surveying, skimming, scanning, reading for full comprehension, reading between the lines (inference), and reacting personally to reading texts. Teaching these learning strategies to your intermediate students can greatly improve their reading comprehension.

The Language Level Issue: In his excellent discussion of top-down and bottom-up teaching, Norris argues that the teaching community’s eagerness to focus on top-down teaching is sometimes misguided. “Many of the listening materials on the market today are concerned chiefly with helping learners become more adept at improving top-down skills by having them (identify relevant information while ignoring unnecessary details.)”

He adds, “In order to simulate the knowledge that native speakers bring to listening, learners are often provided with vocabulary lists prior to the task and told who the speakers are, what the situation is, and what the topic is about. However, scant attention is paid to the phonological characteristics that mark informal speech. This seems a bit like putting the cart before the horse.”

Norris makes a strong case that teachers must develop both bottom-up and top-down skills, especially at the lower levels. “Teachers are asking a lot from their students… when top-down listening tasks are given without first assessing the students' ability to do bottom-up processing.” His argument is sound. Learners need many micro-skills learners for bottom-up processing, and a good teacher neglects them at his peril. This applies especially to beginning and early intermediate students.

Wrap-up: The main conclusion of this discussion is that we need to feed both learning processes when we are teaching our students.

How and when can we use top-down processing? When you are teaching, make sure your students are aware of the format and general content of a reading, for example. Tell them they are going to read a ghost story, for example, and then elicit ideas about what the content might be, what vocabulary might occur, and so on. This switches on the ghost-story schema in their brains, and also begins activating their English skills. You can do the same with listening. Tell them you are about to listen to a sports broadcast on the Football World Cup. Elicit information about football and the vocabulary they might expect to hear, and so on. Also, of course, a CL teacher is constantly using authentic activities to teach. Thus, a role-play “in the restaurant” is by its very nature a top-down comprehension activity.

In these and many other ways, you can take advantage of your students’ ability to use top-down comprehension to get them ready for the upcoming learning activity. As your students advance, you can use more sophisticated top-down schema and strategies.

Bottom-up skills are different. As we have suggested throughout, they are usually more basic and therefore more important for lower-level students. With those students, you need to spend time helping them recognize reduced speech, for example, and irregular spellings. In the early stages of language acquisition, automaticity in word recognition is critical.

Communicative language teaching emulates real-life language acquisition, which means our work has a top-down bias. Your class needs to use authentic activities and materials to function effectively, and those materials tend to be top-down. However, focusing exclusively on top-down teaching creates problems. Especially with beginning students, spend time developing bottom-up skills.

The Gift of Tongues and The Written Word


I recently updated my book, Teach and Learn: Reflections on Communicative Language Teaching, and made it available on Kindle and as an inexpensive paperback. To enjoy a read, please click here.




By Peter McKenzie-Brown

In the beginning, there were only two language skills: listening and speaking. Language began as an aural/oral process. It has always been associated with visual cues, however (consider the pervasive importance of body language in human encounters}, and those visual cues eventually led to the language skills of reading and writing.

In the West, that process began in ancient Sumer, about 3500 BCE. Oddly enough, reading, writing and arithmetic developed out of early accounting systems, rather than the other way around. Reading and writing extended language in quite an extraordinary way. From a function restricted to ear and mouth, they turned it into one that can also be conveyed by eye and hand.

The gradual development of widespread literacy led to many changes in the human condition. Most notably, it liberated language from the immediacy of the spoken word. Both reading and writing require more time than the aural-oral skills, and they tend to encourage thought. The following lists compare spoken and written language, with item #1 in the first group mirroring item #1 in the second group, and so on.

Listening and Speaking
1. Listening and speaking involve impromptu, informal, colloquial language.
2. Unfamiliar national and regional accents and pronunciation problems cause difficulties in comprehension.
3. Meaning is conveyed by word stress, intonation and body language.
4. Gestures and expressions aid understanding.
5. Speakers speak in real time; listeners participate immediately.
6. People easily develop native-language listening and speaking skills.
7. Speech is essentially impermanent.


Reading and Writing
1. Reading texts tend to be organized, formal and stylized.
2. Alphabets and ideographic-style writing systems (think Chinese writing) vary greatly in complexity and approach.
3. English orthography (spelling) is highly idiosyncratic.
4. Meaning is enhanced through punctuation and writing style.
5. Writers have time for corrections; readers can puzzle out meaning.
6. Learning to read and write requires conscious effort.
7. The printed word is documentation.


To read and write, we need six things. In the balance of this commentary, I will review them, and consider their implications for the English teacher.

The Roman Alphabet: English-language learners need to recognize the letters of the Roman (also called the Latin) alphabet. It is very difficult to understate the impact of this hoary old alphabet on western civilization. According to some theorists, this alphabet uses so few letters to represent words that it helped Westerners become highly analytical, and thus had a huge impact on the western mind and outlook.

The Roman alphabet is the dominant writing system in most of the world. The primary alternatives are the Cyrillic alphabet (used in the former Soviet Union), the Arabic alphabet, the Brahmic alphabets of India and parts of Southeast Asia, and the ideographic systems of China, Korea and Japan. The latter are not alphabets.

Phonics:
Also known as the phonetic method, this is a system of teaching children to read. It is commonly used to teach young learners to read in their mother tongue. In this system learners are taught the sounds which the letters represent, and then try to build up the sound of a new or unfamiliar word by saying it one sound at a time.

Phonics can be used for older learners that use either ideographic or non-Latin alphabets. The main difference is that older learners have probably already learned their own writing system, so they will bring to the learning process strategies based on that experience. A useful embellishment on phonics is to have the students spell words out loud as they encounter them in writing. Thus, “ant” is “ay en tee.” This helps develop the students’ ability to remember and recognize the word.

Handwriting and Keyboards: Remember that the printed word is essentially speech produced through our hands. Until recently, the normal progression of things was that we would first learn to write, then move on to cursive writing (rounded script). In recent years, however, cursive has been given short shrift in the West, as youngsters increasingly used keyboards.

Does this matter? According to one observer,
The loss of handwriting … may be a cognitive opportunity missed. The neurological process that directs thought, through fingers, into written symbols is a highly sophisticated one. Several academic studies have found that good handwriting skills at a young age can help children express their thoughts better

Whatever the case, most teachers in Western countries do not spend a great deal of time on cursive writing. EFL teachers are less likely to spend time with their students working on it, except in unusual circumstances. In most cases, to be able to print in English is enough.

It is essential that English-language learners acquire as soon as possible the ability to recognize and produce written words. And since the computer is not going to go away, it is often useful (it depends on class assessment and the nature of the assignment) to insist on typewritten work.

Orthography: Orthography is the fancy work for spelling, and English spelling is more irregular than any other on the planet. As the table below illustrates, the letter combination “ou” can be pronounced in eleven ways, while we can create the “long e” sound with eleven different spellings.
Letters “ou”
tough, tour, dough, famous, bought, you, should,
journey, loud, flour, cough.
Sound “ee”
paediatric, me, seat, seem, ceiling, people, chimney,
machine, siege, phoenix, lazy.

When you teach vocabulary, it is critical that you point out irregular spellings. Because of the oddities of accepted English spelling (think “straight” and “protégé”), it is often quite difficult for students – especially those who speak non-European languages – to develop quick word recognition. This requires frequent practice. However, as the following passage illustrates, native speakers with sophisticated language skills can recognize words with great efficiency.
The phaomnneil pweor of the hmuan mnid
Aoccdrnig to rsreeach at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteer be at the rghit pclae. The rset can be a total mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe. Asbouellty amzanig huh?

Punctuation: What stress and pronunciation do to the melody and rhythm of speech, punctuation does for the written word. Punctuation skills are to reading and writing what phonology is to listening and speaking.

English punctuation is highly sophisticated, and it is difficult to teach. However, consistently and from the beginning you should stress the basics: capitalize the first letter in a sentence, the pronoun “I” and proper names; put a full stop at the end of every sentence; indent paragraphs. The more sophisticated functions (commas, semicolons, colons, dashes, writing schema and so on) come much later.

Inflections and sentence structure: Good writing requires good grammar. In spoken English, fluency is mostly more important than accuracy. In written English, the opposite is true. Good writing requires good grammar. Because readers have time to study and analyse written English, they are more aware of errors in inflection (he walks, he walked), and other features of language structures than when they are in aural/oral mode. The same applies to spelling. Also, grammatically correct structures enable readers to identify parts of speech, and this aids them in their understanding.

A brilliant illustration of the importance of structure in written English can be found in Lewis Carrol’s famous nonsense rhyme, “Jabberwocky.” The story begins,
Twas brillig, and the slithy toves/ Did gyre and gimble in the wabe;
All mimsy were the borogoves,/ And the mome raths outgrabe.

In this poem, all of the content words are meaningless. Yet because Carrol’s grammatical structure is flawless, we have no trouble identifying the parts of speech and the inflections of these nonsense words.

“Toves,” “borogoves” and “raths,” for example, are all plural nouns. The other nonsense words are either adjectives or verbs; indeed, "outgrabe" is clearly an irregular verb in the simple past tense. The one ambiguity in this stanza is the word “brillig”. We don’t know whether it is an adjective or a noun, but in terms of sentence structure it is clearly a complement.

Because of the importance of structure in the written word, when you teach writing you must stress strategies – pre-writing activities, revision, dictionary use, spell-checking and peer review, for example – to help students get their work up to an acceptable standard. You must also, of course, let them know what that standard is.

Words, Words, Words



I recently updated my book, Teach and Learn: Reflections on Communicative Language Teaching, and made it available on Kindle and as an inexpensive paperback. To enjoy a read, please click here.


By Peter McKenzie-Brown

You are studying a foreign language, you want to learn ten new words every day, and the mental task of managing your growing word list seems formidable. To put the job into context, consider the following from linguist Stephen Pinker.

“Children begin to learn words before their first birthday,” he says, “and by their second they hoover them up at a rate of one every two hours. By the time they enter school children command 13,000 words, and then the pace picks up, because new words rain down on them from both speech and print. A typical high-school graduate knows about 60,000 words; a literate adult, perhaps twice that number.”

Smaller than a toddler’s daily intake, your ten-word vocabulary list suddenly seems like a pauper in a palace. And the problem of properly learning vocabulary involves much more than remembering words. In the classroom, only a few words and a small part of what the learner needs to know about a word can be dealt with at any one time. For the common words, which often have multiple meanings and complex nuances, you can only teach a bit at a time. The more information you present, the more likely your learners are to misunderstand.

For both teacher and learner, vocabulary is a huge challenge. But help is at hand from vocabulary researcher Paul Nation, whose magisterial 480-page tome, Learning Vocabulary in Another Language, offers endless insights into the science and practice of teaching and learning vocabulary. He calls his preferred method of vocabulary teaching the direct approach.

Nation describes vocabulary learning as a “meeting” between the learner and the word, and he stresses that it only makes sense to have close encounters with common, useful words. Most teachers emphasize the most common 2000 English words. The most widely accepted list is available on the Internet by googling Michael West’s General Service List.

“Useful vocabulary needs to be met again and again to ensure it is learned,” Nation says. “In the early stages of learning the meetings need to be reasonably close together, preferably within a few days, so that too much forgetting does not occur. Later meetings can be very widely spaced with several weeks between each meeting.”

There are essentially four ways to learn and teach high-frequency words.
• One is direct teaching, mentioned earlier. For the language teacher, explaining vocabulary is a critical part of classroom duties.
• Also, encourage your students to participate in direct learning, which involves study from word cards and dictionary use.
• A third method, incidental learning, can involve guessing from context in extensive reading or through word use in communicative activities.
• The fourth method Nation calls “planned encounters.” These encounters include vocabulary exercises and graded reading – that is, using reading materials like shortened novels with reduced vocabulary for language learners.(Graded readers are available in many language teaching bookstores.)

Nation’s direct approach to vocabulary teaching is built upon three main ideas. First, vocabulary teaching should focus on high-frequency words that will be of continuing importance for the learners. As a teacher, you have a duty to pass over low-frequency words completely or with little comment. Also, you have to make sure the learners come back to the word frequently, to diminish the power of forgetfulness.

Also, when you teach a word you should focus on its “learning burden” – that is, the features of the word that actually need to be taught. These can differ quite dramatically from word to word. Take the word “think.” You need to explain that it is an irregular verb; that it includes the irregular spelling “thought”; and that “thought” can also be a noun.

Finally, direct teaching should be clear and simple. To learn a word in all its complexity, learners need to meet it many times. Don’t try to teach a complex word – for example, the many meanings of the word “right” – in one sitting. That kind of intensive vocabulary teaching takes place in boring classrooms, and it frequently leads to perplexed students.

Confessions of a Language School Junkie



By Peter McKenzie-Brown

Many people in Thailand’s expat community teach English, and many more are learning Thai. Combined, they have more than a passing familiarity with the frustrations of language learning. But help may be at hand: “If you follow a few basic rules, you can take the ordeal out of language learning,” says Dr. Lynn Morris. The occasion was a presentation at Chiang Mai University (CMU), and Lynn called his talk “The Confessions of a Language School Junkie.”

An economist by training, during the last 12 years Lynn has studied five languages in seven countries at 15 different language schools. He only moved to Chiang Mai three years ago, but has already developed conversational fluency in Thai.

In his seminar, he offered ideas about language study from a learner’s perspective – and in his case, a learner with a bad memory. His audience included foreign students training to be English teachers in Thailand, and English instructors from CMU. Lynn’s presentation offered suggestions for learners based on his own experience and research. Noting that the great majority of language school students give up long before they reach conversational fluency, he stressed motivation above all. “Motivation matters.”

But suppose you are motivated. What can you do to speed up your language learning? You need to begin by understanding that most students study too little and try to learn too much. No one can realistically learn more than ten new words a day, for example, but learn new words you must. Says Lynn, “Vocabulary is king in language learning, and verbs are the queen. Ninety-nine percent of the time that I can’t do something in language, it’s because I don’t know the right word.” As a personal aid to his language study, he has created a system of vocabulary cards and voice recordings for pronunciation practice. Technically speaking, this system uses a principle known as anticipated graduated interval recall.

Lynn’s language regimen has five deceptively simple rules. First, “Repetition is the mother of mastery.” Use it. Another imperative is this: learn the most common words in your early days of language learning and move progressively on to those less frequently used. Third, get the pronunciation right. “If you can’t pronounce a word,” Lynn says, “you can’t memorize it.” Vowels are the biggest pronunciation problem for most people, so make this an area of special effort. Fourth, learn the vocabulary before you begin a reading practice. After all, reading exercises are about developing reading fluency rather than acquiring new words. Finally, spend 80 percent of your study time reviewing what you have already learned.

A vocabulary fetishist in every way, Lynn suggests that you can actually define the stages of language learning by word count. For example, a learner who has only mastered 500-1,000 English words can have no more than functional proficiency. By contrast, fluent conversation in social settings requires 3,000-8,000 words. And to understand TV news, read newspapers or participate in group conversation, you need 5,000-10,000 words. To put all this in context, an adult native speaker can typically use or recognize more than 20,000 words.

A rare few schools can teach languages quickly. America’s government-run Foreign Service Institute, for example, has supremely motivated students (career diplomats, military officers); highly expert instructors; and vast financial and training resources. Even with these enormous advantages, the FSI needs at least ten months to train an adult to work effectively in Thai.

By contrast, most language learners have limited resources and average teachers, so the period of mastery is much longer. Unlikely though it may seem after your first Thai lesson, however, there is no reason why a serious adult learner can’t become conversationally fluent. It just takes time and dedication.
