11. Summary of the new findings of the thesis:

(1) The thesis has systematized the theories about the feeling of happiness of children in the world to supplement the theoretical research system that has only been at early steps in Vietnam in recent years.

The overall study on the researches on the relationship between the exercise of lower secondary school students' right to participate in schools and their feeling of happiness shows that there are several researches in the world on this issue.  The researches result all suggest that children's participation is linked to children's happiness. However, these researches have not mentioned the exercise of children's right to participate in relation to their feeling of happiness in school as well as their overall feeling of happiness in life.

The concept of students' feeling of happiness is considered on two aspects: (1) general feeling of happiness of children is approached according to Diener and collaborators’ theoretical model, including: satisfaction with life, more positive and less negative emotions and (2) satisfaction with school.

The theoretical model of the thesis is built upon the relationship between the exercise of the children's right to participate in school and the children's feeling of happiness. The relationship between the implementation of the children's right to participate at school and the feeling of children's happiness is the interconnected connection between the actions and acts that realize the regulations on children's right to participation children in school and their subjective positive psychological state reflected in the experience of positive emotions outperforming negative emotions and satisfaction with life in general, with school in particular in a way.

On the basis of inheritance and systematization of researches in the world and in Vietnam on feeling of happiness is experiencing more positive and less negative emotions and having satisfaction with school (3-composition-happiness) and overall satisfaction with school. Teachers' facilitation, support of friends and students’ personal factors also affect their feeling of happiness at school.

The thesis has pointed out the research trends on the participation of children and students in school activities. Most of the results of researches showed that children's participation affects children's feeling of happiness.

In practice

- The exercise of children's right to participate in schools is limited and mostly at only providing students with information. The content of the participating in activities or expressing opinions is also very limited. It affects the children's feelings of happiness when participating in activities to exercise the right to participate at school and the relationship between the two.

- Research results also show that exercising the right to participate of students in school brings them a lot of positive emotions when participating.

- There is a relationship between the exercise of children’s rights to participate in secondary school and their feeling of happiness, however the relationship is at moderate and weak level;

- There is no difference in the correlation level between children's right to participate with feeling of happiness in school and general feeling of happiness in life;

- The groups of factors related to school (teachers, friends, study attitude etc.) have significantly higher prediction level for happiness in school;

- Student’s feeling of happiness at school depends on many different factors, of which exercising children's right to participate is only one of the factors affecting students' feeling of happiness;

- Practical research results show a very interesting aspect that is exercising the right to participate does not have too much of a direct effect on students' feeling of happiness in school, but research results show the intermediating factors with the exercise of children's right to participate such as self-assessment, recognition and support from teachers and friends will help them gain the general feeling of happiness in life as well as improved happiness in school;

- There is no difference in feeling happiness when exercising the right to participate in schools between groups of students of public and private schools.
