This is the second part of my letter. I know it is still very confusing but I don't have a clear idea about the project yet. Thank you very much for helping me!

Question

1) As a matter of fact, our school had, within the scientific branch, a sort of course of excellence for science until last year.
2) This course, which included three hours of science a week instead of the current two, has been cancelled to comply with the new school reform.
3) These teachers believe that the involvement in this project could motivate the reintroduction of such a course into next year's school offer plan (I don't know how to translate the plan including the activies offered by the school during the school year).
4) They also believe that these students should receive extra afternoon tuition in English to cope with the scientific terminology. During the two (or more?) annual meetings they will summarise (?? the results achieved to their French and German partners.
5) In my opinion, a 10-hour crush course should be organized in September which will be ? by another ten-hour course in which students will be supported mainly in translation activities.
6) Do you think they could refer to the interent site "kahn" you once suggested to me to train their knowledge of science in English. (This is a real question. Keep in mind that their level of English is "intermediate", that is they have an intermediate knowledge of the English grammar).
7) I urgently need to know what do you think about this idea before tomorrow so that I can express your point of view to them.
Thank you very much for your cooperation.

Answer 1

I'm deleting all the personal things since this is a business letter. No need to make excuses!

I'm terribly sorry that I didn't manage to write you earlier. Our science teachers have decided to meet tomorrow to better define the theme and objectives of the project. They would like to know a few more things before the preliminary meeting.

First of all, do you still think the project should concentrate mainly on the biodiversity in water and waterways? Do you believe our physics teachers should be involved in the project as well? Some of our science teachers would like to include a second group of students instead of individual students selected from different classes.

Our school had, within the scientific branch, a sort of course called Excellence for Science until last year. This course, which included three hours of science a week instead of the current two, has been cancelled to comply with the new school reform. These teachers believe that involvement in the aquatic biodiversity project could motivate the reintroduction of such a course into next year's course proposals. They also believe that these students should receive extra afternoon tutorials in English to cope with the scientific terminology. During the two or more annual meetings, they will summarise the results achieved by their French and German partners. In my opinion, a 10-hour crash course should be organized in September, to be followed by another ten-hour course in which students will be supported mainly in translation activities. Do you think they could refer to the website www.kahnacademy.org you once suggested to me to teach science concepts in English. I must know what you think about this idea before tomorrow so that I can relay your point of view to our teachers.

I'm not sure. I think it'd be possible if someone were in the room to help with vocabulary -- I've done this type of thing before in English classes when I've had students who have had only 2 years studying English -- I showed a video (maybe a segment related to something we had read in class, such as Huckleberry Finn) and then I'd stop it at times to make sure everyone understood what had been said or shown.

I found kahnacademy.org to require sign-ins now -- this collection in YouTube might work better: http://www.youtube.com/user/khanacademy#p/p

Answer 2

There needs to be a question mark at the end of this sentence in your letter:

Do you think they could refer to the website www.kahnacademy.org you once suggested to me to teach science concepts in English?
