A tutor of the Tema International School, Ms Felecia Sackey, says children ought to be exposed to situations that would enable them learn more about other cultures and challenges that they are not familiar.
This should be in addition to the traditional mainstream subjects that are studied by pupils and students.
Ms Sackey said by so doing, these children tend to gain a better understanding of the world and in the long run grow to be better equipped to help build the society.
She was speaking to journalists at the Kotoka International Airport when she returned home with five students of the School who represented Ghana at a Model UN Conference in Switzerland.
Ms Sackey observed that for education to be complete, it was important to ensure that children grew into adults who were very open minded and ready to open up to and understand situations that they were not necessarily familiar with.
Speaking about their experiences, the students said the exposure from the conference had greatly boosted their confidence. "I never knew I could speak with enough confidence before a very large crowd of people," one of them said.
They said they had also gained a lot of insight into issues bordering on human rights as well as the horrors of war and the need to ensure peace at all costs within nations.
Ms Princess Pappoe, who was on the Security Council and Ms Mary Paintsil who was on the Human Rights Committee emerged as runners-up out of the 200 participants.
The students also had an award for the best dressed delegation at the conference.
The conference which was organised by the International School of Basel in Switzerland was attended by over 200 children from Ghana, Switzerland and Germany.
Students who attended the conference were Kwasi Adi-Dako, Ms Joycelyn Abeasi, Dela Atti Kesse, Mary Sorotow Ann Paintsil and Princess Pappoe.
