Problems that hinder a better use of Science Education in the teacher’s training and Secondary Education

Science Education today can be considered as a whole and coherent body of specific knowledge with a "hardcore" in which the most direct issues related to key aspects of teaching and learning can be found.

In this paper, some of these problems are discussed, and some proposals to make progress in solving them are justified
