Parallel reading: ocean level rise

This is an example of a parallel reading task from the Y9 (CEFR A2) page of frenchteacher.net. I like the concept of parallel reading as a way to give access to harder, often more interesting texts. The main downside is that the language is not deeply processed (since there is not much built-in recycling and intensive work involved). Another possible downside is the emphasis (in some texts) on less frequent vocabulary. This doesn't worry me much since, in French, many more technical words are cognates and often, though not high frequency, the words are important, as in the example below. 

Overall, for me, therefore, parallel texts are a useful occasional way to spice up lessons and give experience with harder texts.

The example below is on the important issue of sea level rise. Since 1901, the average level of the oceans has risen by between 15 and 25 cm. Most of this rise is, according to climate scientists, down to human-induced climate change. Feel free to copy and use. There are plenty more examples of parallel reading texts on the Y7, Y8 and Y9 pages of my site.

As well as the two texts, there are correct sentences to spot and a vocab grid to complete. This ensures that students do much more than a cursory read. You could exploit the materials further if you wanted.

Les causes de la montée du niveau de la mer

La température de la planète ne cesse d'augmenter sous l'effet de l'action de l'Homme. Les activités humaines utilisent des ressources fossiles (gaz, charbon et pétrole) qui libèrent beaucoup de gaz. Ces gaz forment une couche qui concentre la chaleur sur Terre. Ce sont les gaz à effet de serre (GES).

Au fil des années, l'effet de serre naturel s'est renforcé à cause de l'augmentation du volume de ces gaz produit par l'Homme. Donc la température atmosphérique augmente, les glaces terrestres fondent et le niveau de l'Océan s'élève. Cette montée des eaux menace directement certains territoires insulaires.

Par action de la chaleur, les glaces continentales (accumulation de neige, glaciers, calottes polaires) fondent. Ce surplus d'eau se transfert dans l'Océan, entraînant une augmentation de son niveau. Il est important ici de bien distinguer les glaces polaires situées sur les continents, de la banquise déjà présente dans l'Océan. Si la banquise fond, ce qui est déjà le cas, cela ne fera pas monter le niveau des mers: la fonte des glaçons dans un verre d'eau ne fait jamais monter le niveau de l'eau !

Il existe un autre phénomène, appelée la dilatation thermique de l'eau. En se réchauffant, l'eau se dilate, c'est-à-dire qu'elle « gonfle » et prend plus de place. Pour une même quantité d'eau, l'eau chaude occupe un volume supérieur à l'eau froide. Cette dilatation n'est pas anecdotique puisqu'elle représenterait entre 30% et 50% de la hausse globale du niveau de la mer.

Depuis 1901 le niveau de la mer a augmenté de 15-25 cm.

The causes of sea level rise

The temperature of the planet continues to increase under the effect of the action of Man. Human activities use fossil resources (gas, coal and oil) which release a lot of gas. These gases form a layer that concentrates heat on Earth. These are greenhouse gases (GHGs).

Over the years, the natural greenhouse effect has increased due to the increase in the volume of these gases produced by humans. So the atmospheric temperature increases, the terrestrial ice melts and the level of the ocean rises. This rising water level directly threatens certain island territories.

By the action of heat, continental ice (accumulation of snow, glaciers, polar ice caps) melts. This excess water is transferred to the ocean, causing an increase in its level. It is important here to clearly distinguish the polar ice located on the continents, from the pack ice already present in the ocean. If the pack ice melts, which is already the case, this will not raise the sea level: the melting of ice cubes in a glass of water never raises the water level!

There is another phenomenon, called the thermal expansion of water. As the water heats up, it expands, that is, it "swells" and takes up more space. For the same quantity of water, hot water occupies a greater volume than cold water. This dilation is not anecdotal since it would represent between 30% and 50% of the global rise in sea level.

Since 1901 sea levels have risen between 15 and 25 cm.

What is skill acquisition theory?

For this post, I am drawing on a section from the excellent book by Rod Ellis and Natsuko Shintani called Exploring Language Pedagogy through Second Language Acquisition Research (Routledge, 2014). Skill acquisition is one of several competing theories of how we learn new languages. It’s a theory based on the idea that skilled behaviour in any area can become routinised and even automatic under certain conditions through repeated pairing of stimuli and responses. When put like that, it looks a bit like the behaviourist view of stimulus-response learning which went out of fashion from the late 1950s. Skill acquisition draws on John Anderson’s ACT theory, which he called a cognitivist stimulus-response theory. ACT stands for Adaptive Control of Thought.  ACT theory distinguishes declarative knowledge (knowledge of facts and concepts, such as the fact that adjectives agree) from procedural knowledge (knowing how to do things in certain situations, such as understand and speak a langua...

Zaz - Si jamais j'oublie

My wife and I often listen to Radio Paradise, a listener-supported, ad-free radio station from California. They've been playing this song by Zaz recently. I like it and maybe your students would too. I shouldn't really  reproduce the lyrics here for copyright reasons, but I am going to translate them (with the help of another video). You could copy and paste this translation and set it for classwork (not homework, I suggest, since students could just go and find the lyrics online). The song was released in 2015 and gotr to number 11 in the French charts - only number 11! Here we go: Remind me of the day and the year Remind me of the weather And if I've forgotten, you can shake me And if I want to take myself away Lock me up and throw away the key With pricks of memory Tell me what my name is If I ever forget the nights I spent, the guitars, the cries Remind me who I am, why I am alive If I ever forget, if I ever take to my heels If one day I run away Remind me who I am, wha...

Longman's Audio-Visual French

I'm sitting here with my copies of Cours Illustré de Français Book 1 and Longman's Audio-Visual French Stage A1 . I have previously mentioned the former, published in 1966, with its use of pictures to exemplify grammar and vocabulary. In his preface Mark Gilbert says: "The pictures are not... a mere decoration but provide further foundation for the language work at this early stage." He talks of "fluency" and "flexibility": "In oral work it is advisable to persist with the practice of a particular pattern until the pupils can use it fluently and flexibly. Flexibility means, for example, the ability to switch from one person of the verb to another..." Ah! Now, the Longman offering, written by S. Moore and A.L. Antrobus, published in 1973, just seven years later, has a great deal in common with Gilbert's course. We now have three colours (green, black and white) rather than mere black and white. The layout is arguably more attrac...
