The correct answer to this open question is the following.
The THREE practical strategies in which my school could involve learners in community work to develop a sense of social responsibility would be the following.
1) Donate our old clothes that are in good condition, but we have to take them personally to the young men and women that would receive. This involvement could create greater awareness of the social issues in your community in that we can directly talk with these people and try to show compassion for them.
2) Organize a thematic party and all the money would be donated to an orphanage. This involvement could create greater awareness of the social issues in your community in that we would ask the institution what their necessities are, and we directly buy them and supply them to the institution.
3) Collect our used books and donate them to a public elementary or High school. This involvement could create greater awareness of the social issues in your community in that we would include a series of classes or lessons so we can share some information that could be useful for the students.
