You ask the following: How to improve secondary education outcomes?
As I see it, there various ways to improve secondary education outcomes. Chiefly amng then are the following:
1) The use of appropriate technology, such as computers, Internet, and so forth.
2) The use of active methods. In contrast with the traditional and conservative methods, in the active methods the teacher is more a mentor and organizer of learning experiences and situations such that students come to understand, reinvent and reconstruct everything they learn than a simple trasnmitter of ready made or established truths imposed on students from outside.
3) To make use of teachers who are authoritative, not authoritarian nor permissive, figures. Authoritative teachers are demanding in cognitive terms, but warm in their social interactions with their students. Authoritarian teachers are demanding in intellectual terms, but cold in their social interactions with their students. And permissive teachers are guided, say, by the French slogan "laissez faire, laissez passed, laisser aller" (Let's it go). There is amassing evidence that shows that, in contrast to authoritarian and permissive teachers, authoritative teachers foster the student's level of psychological development, be it congitive, social, moral emotional, ans so forth.
4) To make all that is possible to have intrinsically, not extrinsically, motivated students, that is, students who like learning to fulfill their intellectual curiosity and look for the unknown, not students who study, for example, to have good exam marks.
In my opinion for better results the student must be disciplined in his study and prepared to face life as well as a self-taught there are few people who dedicate their free time to continue studying or work overtime to get Meet your goals T goals in this sense the student should be able to have such discipline that allows him to be self-taught and always be one step ahead of others and to acquire such discipline is needed motivation to be always motivated you need a good self-esteem do not forget that the limit you put it.
