النماذج في الكيمياء وأهميتها في عمليتي البحث العلمي والتعليم
In our work, we aim to study the importance of models in scientific research and education. This work also enabled us to touch some aspects of how science represents by models, whose basic functions are description, representation, interpretation, and prediction. And that scientific models and theories remain subject to agree of standards certification, it is important to emphasize here that abandoning a model or theory does not often mean abandoning it completely or denying the effort of scientists who have developed it. It always preserves some aspects of the truth. It has become clear to us that the scientific event is not a raw event, that is, the researcher in science is actually simplifying, and the calculation variables whose impact on the studied phenomenon can be neglected. The scientific event, then, is the product of reducing a complex reality to a simple, artificial one that can be studied. It is also confirmed that science is a collective effort, and that the scientific facts that seem to be intuitive today were taken among the senior scientists, and even a Longstanding polemic between them before accepting over, Science is no more than an attempt to interpret reality, but it is an open interpretation, that is, it is not the final. We also recognized the specificity of models in chemistry through a special case study: models of acids and bases. They move from definitions based on sense to abstract concepts that have no direct link with reality. Chemistry has to rise to science; it has to move from perceived to abstract. That is to say, to the extent that it is possible to generalize in so far it is separated from the directly understood reality. (Published abstract)
