Our research is at the crossroads of educational research conducted on education systems and lines of improvement.We are interested in the teaching and learning of chemistry, one of the most important disciplines that contribute to the scientific training of students. Our thinking is essentially based on: literature searches, the findings of our field studies and our experience as teachers of physics and chemistry. The obstacles that we faced involve almost all components of the teaching-learning system and the different priorities for their improvement revolve around the following factors: improving curriculum content and textbooks, improving the language used in teaching chemistry,orientation of teaching chemistry to an experimental approach, changing thoughts on chemicals and teacher training and “promotion” of their profession. Therefore it is critical to build collaboration and coordination of efforts of all
partners in the education system and the teaching-learning of chemistry in high schools in Morocco.
