Gender Issues, are they still necessary?

Is the inclusion of gender aspects necessary in the formation of knowledge? Is gender a determining factor in learning, teaching and working? If there are differences due to gender and we disregard them as if they did not exist, then maybe the quest for neutrality or equality is merely a false impression on the part of the observer. We are presenting here the results obtained from a study carried out with secundary students and first-year Engineering students. The opinions of these two groups show that the stereotypes of gender and therefore the different perceptions of boys and girls, still prevail and that they do affect their professional choices and motivations in their teaching-learning process.
