Teaching with no books

Dianne Bell

I have started teaching in a language school suggesting no books to teach except for some magazines. These show the framework what should be worked on, for example, countability and that’s it. When it was offered I accepted the job easily because it seemed challenging and at the same time simple but now I’m out of reliable materials. Please help me out in what ways I can find materials for all the suggested frameworks.

What exactly are you supposed to be teaching (i.e., conversation, grammar, business English, etc.)? Can you give more examples of the “frameworks”? If there are no books or resources, it sounds like the school wants you to do conversation classes. These can be easy to prepare if you tell the students to come prepared with a topic to discuss. Then, you can assist them with keeping a conversation going, asking questions, giving opinions, etc.

 Hi, I think it really does depend on the students and the level you are teaching to. I have found a lot of online resources are useful, especially news articles. If you just type in “Free online English lessons” or something similar you are bound to find resources. I had to teach like that once. They give you a book with a list of what you should be teaching in each lesson but nothing else. The teacher has to make the lesson up out of thin air each time, and it’s pretty time-consuming.

There are so many other resources out there for teachers to use, online and off, that teaching without textbooks is becoming more and more acceptable including websites, iPod lectures and field trips — that will encourage you to toss out your textbooks. Before you can toss out the textbook and replace it with technology tools, you’ll need to understand how your students — whatever their age — respond to and work with technology.

Read the following article and answer question based on the text.

Faced with the unprecedented stream of migrants fleeing war and trauma in the Middle East and North Africa, Europe needs to take clear-sighted action.

        For its part, the UK has agreed to take 20,000 refugees, a significant portion of whom will likely be children and orphans according to report. One key aspect in ensuring their smooth settlement in the UK will be providing these refugees with language training.

       Many Syrians are well-educated and many speak fluent English. Others, however, do not speak English well enough to function professionally within the UK. The issue of language is so fundamental to our lives that we often overlook it. Several multi-million pound training contracts have failed to be delivered on account of not addressing the language barrier. All the goodwill, financial backing, and technical expertise to deliver needed medical, economic, military,engineering, or navigational training may be present; but unless there is a shared language in which to impart that knowledge, little will be accomplished.

        One of the biggest misconceptions about language is that if you “just go to the country,” you’ll pick it up. Many people believe that immersion will guarantee fluency; yet you may well know several immigrants who have been in this country for years and still only speak broken English. You might also know dozens of expats in various countries across the world who have failed to pick up the local languages of their host countries. Training and effort are both necessary.

        Though not a guarantee of fluency, immersion is a wonderful opportunity. The first issue we need to address with respect to refugees is ensuring that those who come will actually be immersed. That is, that they will be welcomed as part of larger communities, and not simply join communities of other refugees. On the other hand, immersion is just an opportunity, and in order to take full advantage of it, training and education are required. In terms of refugees, we need to consider options for the provision of language training, whether by self-study, classroom instruction, private tuition, or some combination of the three.        

       The array of needs is staggering. In truth, every language learner has a different set of learning objectives, and will require different training to meet those objectives. Coordinating the actual needs with providers in different regions and accounting for different personal schedules and start dates is a significant challenge. It is, however, a challenge that must be addressed immediately, as proficiency in English will be a key enabler of success for refugees in this country.

Q761910 Inglês

Answer question about the text below:

A US dentist who killed a lion in Zimbabwe says he regrets shooting the well-known animal. 
In a written statement, Walter Palmer insists that he thought he was on a legal hunt and that he "deeply regrets" his actions. 
Cecil the lion, known for his black mane, was about 13 years old, and a famous attraction for wildlife tourists in Zimbabwe. But earlier this month, it’s understood the big cat was tempted outside a national park using bait and allegedly shot with a bow and arrow by Palmer. 
"Cecil was collared. You may want to know what that means. Collared is an animal which is under surveillance and a GPS system which is being used for research, for different things…” 
Wildlife officials accused Mr Palmer of killing Cecil, without a permit, after paying $50,000 to two people who lured the beast to its death. 
"The person involved, or the offender, is a gentleman who is an American called Walter James Palmer. Walter James Palmer is the guy who came into the country around the beginning of this month of July and was enticed, we're not quite sure yet, to harvest this particular lion. The proper market value for this lion, which is a big treasure, would be around $100,000 US dollars.” 
Police in Zimbabwe say two people have been arrested and that Mr Palmer may also face poaching charges. If convicted, the two men would be required to pay $20,000 in compensation, but the court may impose an additional jail term. 
According to the Zimbabwe Parks and Wildlife Management Authority, investigations show that the killing of Cecil was illegal because the land owner was not allocated a lion on his hunting quota for 2015. 
Lions are not a protected species in Zimbabwe. The country issues annual permits allowing foreign hunters to kill wildlife like elephant, buffalo and lion, and say doing so allows it to raise money for conservation.

                                                            Words that went extinct

                                                                                                                                           By Kimberly Joki

Dictionaries incorporate new words every year. Some are pop culture inventions like jeggings, photobomb, and meme. Other words, like emoji and upvote, spring up from technology and social media. Dictionaries respond by creating definitions for anyone who cares to know what a twitterer is. And thank goodness they do; you can learn what an eggcorn is simply by turning a few pages in your trusty updated dictionary.

    Interestingly, not all newly added words are recent developments. The Oxford English Dictionary June 2015 new words list included autotune, birdhouse, North Korean, and shizzle! North Korea was founded in 1948. The initial release of the autotuner audio processor was in 1997. Before adding a slang term like shizzle, dictionary publishers weigh the current popularity, predicted longevity, and other factors. Just this year alone, the Merriam-Webster Dictionary welcomed about 1,700 new arrivals.

    With more and more words coined every year, dictionaries couldn’t possibly add them all to their existing word banks. Can you imagine a dictionary containing all the words ever used in English? It would be impossible to lift! With each yearly edit, dictionary editors must discard some words to make room for new ones.

(…)

    The Sami languages, spoken in Finland, Norway, and Sweden, reportedly include more than 150 words related to snow and ice. In the 1590s, the English language had a word for recently melted snow—snowbroth. Now, English speakers simply call it water or melted snow. In fact, words that are markedly specific seem more vulnerable to extinction. A 19th-century dictionary included Englishable, a term to describe how appropriate a word is for the English language. However, English is a dynamic language, always accepting and abandoning words. Apparently, Englishable itself isn’t Englishable; it’s now obsolete.

    Do you favor any infrequently used words? If so, use them now and often. . . A word’s best defense against extinction is regular use.

Acid rain and… the facts

www.acidrain.org.ca / Oxford Children´s Encyclopedia


What causes acid rain?

Acid rain is caused by air pollution. When fossil fuels such as coal and oil are burned, two gases, sulphur dioxide and nitrogen oxide, are released into the atmosphere. These two pollutants eventually react with the moisture in the air. When this polluted mixture falls onto the ground, it is called acid rain.

Rain measuring between 0 and 5 on the pH scale, is acidic therefore called ACID RAIN

Acid rain is harmful to the environment. It is hard to control because it may be blown by the wind, falling thousands of kilometers from where it was first formed. For example, much of the acid rain in Canada is caused by smoke from factories and power‐stations in the USA. The acid rain in Scandinavia may come from Britain.

What are the effects of acid rain?

Acid rain has many different effects. It has killed fish in the lakes of North America, Scandinavia, Scotland, and Wales. Vast areas of forest in northern and central Europe are dying because of it, while in many European cities statues and stone buildings are being eaten away by the acid. Acid rain corrodes metalwork such as steel bridges and railings; it also attacks some types of concrete. Even the water that we drink is slowly being polluted by acid rain.  

What are the effects on trees and soil?

One of the most serious impacts of acid precipitation is on forests and soils. Great damage is done when sulphuric acid falls onto the earth as rain. Nutrients present in the soils are washed away. Aluminium also present in the soils is freed and this toxic element can be absorbed by the roots of trees. Thus, the trees starve to death because they have been deprived of their vital nutrients such as calcium and magnesium.

Acid rain is one of the most serious environmental problems of our time. It is a global problems that is gradually affecting our world.

How does acid rain effect lakes?

Lakes that have been acidified cannot support the same variety of life as healthy lakes. As a lake becomes more acidic, various types of fish disappear. Other effects of acidified lakes on fish include: decreased growth, inability to regulate their own body chemistry, reduced egg deposition, deformities in young fish and increased susceptibility to naturally occurring diseases.     

Clean rain usually has a pH of 5.6. It is slightly acidic because of carbon dioxide which is naturally present in the atmosphere. Vinegar, by comparison, is very acidic and has a pH of 3.

What is pH?

This is a measure of how acidic or alkaline a substance is. (See a pH scale below). The initials pH stand for Potential of Hydrogen. Acids have pH values under 7, and alkalis have pH values over 7. If a substance has a pH value of 7. It is neutral‐neither acidic or alkaline.    

                                 

Because the pH scale is logarithmic, a difference of one pH unit represents a tenfold, or ten times change. For example, the acidity of a sample with a pH of 5 is ten times greater than that of a sample with a pH of 6. A difference of 2 units, from 6 to 4, would mean that the acidity in one hundred times greater, and so on.
