The good way to use flashcards to learn vocabulary

To learn vocabulary, there are several systems, and 2 especially used in auto-learning :

• The lists (sorted or not by theme, by frequence). This is the vocabulary notebook our language teachers made us write in the secondary school, the notebook having for them the advantage that its form could be checked even though it was not learned… Because its use showed some obvious limits : The learned vocabulary and still to be learned staying at the same level, we cannot focus on the most difficult words.
• The flashcards, are these small cards with on one side the word in target language and on the other side the word in the origin language. The advantage is that once the word is known, you can remove its card to focus only on the others. Here is a more efficient method. But it is possible to do even better.

We saw that flashcards are a memorization mean through a repetition spaced in time. It happened that a German scientist, Sebastian Leitner, demonstrated in the 70′s that it was possible to maximize the system efficiency by sorting the cards in several groups corresponding to our memorization ability. This is the Leitner system and here is the functioning : We test our knowledge with the cards from one group. If we remember the meaning of the word, we put the card in another group and in the opposite case we put it in the first group. The time duration between each test increases with the groups.

For example, the proposed time durations being only proposals : We have 4 groups. The group 1 includes the words we hardly remember, the group 4 including the words we easily remember. We will check the words of the group 1 every day, the one of the group 2 every 3 days, the one of the group 3 every week and the one of the group 4 every month. If we success on the vocabulary of the group 1, the words we know are put into the group 2 and will be tested a few days later; the known words of group 2 will go to group 3, the ones of group 3 in the group 4 and the one of the group 4 will be considered as definitely known. On the opposite, the words of group 2, 3 and 4 we don’t remember would go directly in the group 1.

Thus you spend more time on the difficult words, you train your memory on the short term but also on the long term. The result is a more efficient memorization activity.

Vocabulary memorization innovative project (1) : memorization technics

In a serie of articles on our current innovative project on memorization of vocabulary in foreign languages, here are some interesting materials  and thoughts which guided our development.

How to… Learn a Foreign Language

Using the tools :

Foreign languages are the ideal subject area for the use of memory techniques. Learning vocabulary is often a matter of associating a meaningless collection of syllables with a word in your own language.

Traditionally people have associated these words by repetition – by saying the word in their own language and the foreign language time and time and time and time again. You can improve on this tedious way of learning by using three good techniques:

1. Using Mnemonics to link words

This is a simple extension of the link method. Here you are using images to link a word in your own language with a word in a foreign language.

For example, in learning English/French vocabulary:

• English: rug/carpet – French: tapis – imagine an ornate oriental carpet with a tap as the central design woven in chrome thread
• English: grumpy – French: grognon – a grumpy man groaning with irritation
• English: to tease – French: taquiner – a woman teasing her husband as she takes in the washing.

This technique was formalized by Dr. Michael Gruneberg, and is known as the ‘LinkWord’ technique. He has produced language books (an example is German by Association) in many language pairs to help students acquire the basic vocabulary needed to get by in the language (usually about 1000 words). It is claimed that using this technique this basic vocabulary can be learned in just 10 hours.

2. The town language Mnemonic

This is a very elegant, effective mnemonic that fuses a sophisticated variant of the Roman Room system with the system described above.

This depends on the fact that the basic vocabulary of a language relates to everyday things: things that you can usually find in a city, town or village. To use the technique, choose a town that you are very familiar with. Use objects within that place as the cues to recall the images that link to foreign words.

Nouns in the town:
Nouns should be associated to the most relevant locations: for example, the image coding the foreign word for book could be associated with a book on a shelf in the library. You could associate the word for bread with an image of a loaf in a baker’s shop. Words for vegetables could be associated with parts of a display outside a greengrocer’s. Perhaps there is a farm just outside the town that allows all the animal name associations to be made.

Adjectives in the park:
Adjectives can be associated with a garden or park within the town: words such as green, smelly, bright, small, cold, etc. can be easily related to objects in a park. Perhaps there is a pond there, or a small wood, or perhaps people with different characteristics are walking around.

Verbs in the sports center:
Verbs can most easily be associated with a sports center or playing field. This allows us all the associations of lifting, running, walking, hitting, eating, swimming, driving, etc.

Remembering Genders
In a language where gender is important, a very good method of remembering this is to divide your town into two main zones. In one zone you code information on masculine gender nouns, while in the other zone you code information on feminine nouns. Where the language has a neutral gender, then use three zones. You can separate these areas with busy roads, rivers, etc. To fix the gender of a noun, simply associate its image with a place in the correct part of town. This makes remembering genders easy!

Many Languages, many towns
Another elegant spin-off of the technique comes when learning several languages: normally this can cause confusion. With the town mnemonic, all you need do is choose a different city, town or village for each language to be learned. Ideally this might be in the relevant country. Practically, however, you might just decide to use a local town with the appropriate foreign flavor.

3. The 100 most common words

Tony Buzan, in his book ‘Using your Memory’, points out that just 100 words comprise 50% of all words used in conversation in a language. Learning this core 100 words gets you a long way towards being able to speak in that language, albeit at a basic level. The 100 basic words used in conversation are shown below:

1. A/an	2. After	3. Again	4. All	5. Almost
6. Also	7. Always	8. And	9. Because	10. Before
11. Big	12. But	13. (I) can	14. (I) come	15. Either/or

Summary

The three approaches to learning foreign languages shown here can be very effective. They help to:

• Point out the most important words to learn
• Show how to link words in your own language to words in a foreign language, and
• Show how to structure recall of the language through use of the town mnemonic.

The EV as “disruptive” technology

An article in the current issue of The Economist asks: “After many false starts, battery-powered cars seem here to stay. Are they just an interesting niche product, or will they turn motoring upside down?”

Read the full article here.

” In 1995 Joseph Bower and Clayton Christensen, two researchers at the Harvard Business School, invented a new term: “disruptive technology.” This is an innovation that fulfills the requirements of some, but not most, consumers better than the incumbent does. That gives it a toehold, which allows room for improvement and, eventually, dominance. The risk for incumbent firms is that of the proverbial boiling frog. They may not know when to switch from old to new until it is too late.

The example Dr. Bower and Dr. Christensen used was a nerdy one: computer hard-drives. But unbeknown to them a more familiar one was in the making. The first digital cameras were coming on sale. These were more expensive than film cameras and had lower resolution. But they brought two advantages. A user could look at a picture immediately after he had taken it. And he could download it onto his computer and send it to his friends.

Fourteen years on, you would struggle to buy a new camera that uses film. Some of the leading camera-makers, such as Panasonic, are firms that had little interest in photography when Dr. Bower and Dr. Christensen published. And an entire industry, the manufacturing and processing of film, is rapidly disappearing.

Substitute “car” for “camera” and you have a story that should concern thoughtful bosses in the motor and oil industries. Internal-combustion engines have dominated mechanized road transport for a century, but the past year or so has seen the arrival of a dribble of vehicles driven by electric motors. That these are the products of small, new firms, or of established non-carmaking companies, supports the Bower-Christensen thesis. But next year the big boys, encouraged by legislative pressure to produce low-emission vehicles, will leap out of the boiling water and join in. “

Note from the author : I remember an article of Shai Agassi (Better Place) explaining that the Electric Vehicle could be compared to e-mail, and Internal Combustion Engined cars compared to traditional written letters sent by Post-office… and that Hybrid Vehicles are like fax ! A mixed combination of both technologies … with all disadvantages !

24h with an Electric Vehicle

The example of Renault Kangoo.
3 ways to re-charge batteries : normal charge (6h), fast-charge (20min), battery exchange (Quickdrop stations, 3 min).

Shai Agassi @ TED.com : the necessity of the Electric Cars industry revolution.

Forget about the hybrid auto — Shai Agassi says it’s electric cars or bust if we want to impact emissions. His company, Better Place, has a radical plan to take entire countries oil-free by 2020.

“Hybrid cars are like mermaids. When you want a fish, you get a woman and when you need a woman you get a fish” (Carlos Ghosn, CEO of Renault-Nissan)
