Bac STI2D: How to revamp the Engineering, Innovation and Sustainable Development major?

On May 12, 2022 from 2:00 p.m. to 6:00 p.m. the technology, innovation and sustainable development exam of the STI2D Matura course will take place. The student shares his best advice for good learning.

The written exam is approaching. It’s time to start the STI2D high school retakes. First thing to do: review the basics. “The Innovation and Sustainable Development Engineering (2I2D) specialization requires a solid knowledge of physics and mathematics,” recalls Pierre-Emmanuel Celtan, Professor of Engineering and Sustainable Development at the Lycée Louis de Foix in Bayonne (64).

So make sure you have thoroughly checked all the principles of these two topics before attacking 2I2D. Then bring all your courses with you: “It is necessary to repeat all the courses of the first and last cycle, since they make up all the knowledge of the last cycle“, he continues.

Plan your revisions

Engineering and sustainable development is a very rich and diverse subject. It deals with the themes of the four disciplines: AC (Architecture and Construction), EE (Energy and Environment), ITEC (Technological Innovation and Ecodesign), SIN (Information and Digital Systems). “This variety of subjects accounts for the complexity of the subject,” emphasizes Pierre-Emmanuel Celtan. Proofread all your lessons. This allows you to estimate the content to be revised and plan your revisions.

Then make cards. To each his own method, but the teacher advises itProvide at least the titles and subtitles for each chapter, which you can then fill in with the important ideas. We can never repeat it enough, but developing a blade is an integral part of the work to be done. It allows you to revise your course and remember important information. Hence the importance of write it yourself.

No dead end in 2I2D

If we can’t ignore any of the areas – especially those we are least familiar with – some are fundamental “because they are systematically useful regardless of the topic”, Pierre-Emmanuel Celtan emphasizes your knowledge of ‘project approach’, ‘flow representation’ and ‘Eco design'”.

It is essential to repeat course exercises, especially for numbering, the basic principle of statics (triangle of forces) and basic electrical engineering. But most importantly, you need to practice running full tests.

Practice for the four-hour event

“The difficulty of the test lies in its duration,” explains the teacher at the Bayonne high school. You have to train with annals without looking at the corrections to “take the rhythm, get used to the length of the effort”..

If a student works through three or four annals subjects and has four hours off, he will develop his ability to quickly find useful information to solve the problem at hand and will not be destabilized if some of it is useless. In fact, “this subject is closely related to real problems. The focus is at least as much on problem-solving skills as it is on achieving quantifiable results,” concludes the teacher.
