Bi-lingual guest speakers in South Africa can bolster self esteem and enliven the proceedings of any meeting but any thought that these same persons can enhance self esteem of teachers (or other people) would surely sound rather unusual, wouldn't it? But it really is not so, as several academic researchers have conclusively proved that guest speakers can indeed boost self esteem of teachers. These researchers have done extensive study on how children of several tightly knit ethnic groups in U.S. receive their education in schools and academic institutions meant for these minorities. In a thorough research on schooling, more particularly, pre-schooling of Latino children, these researchers observed that the most pertinent issue is a continual reassurance to these children about the soundness of their cultural identity and a gradual inculcation in them of a firm belief about the inherent multi-cultural identity of United States as a nation. Their teachers who are in constant contact with these children are naturally the only persons that can make them remain in the mainstream so that they grow up to be contributive citizens of the country. But these teachers, especially if they are bi-lingual, have always found it difficult to thoroughly mingle with children and have often been observed to be at a loss while espousing the soundness of Latino culture. This issue achieves particular poignancy in the backdrop of current undercurrent of anti-immigrant sentiment that seems to be sweeping vast tracts of the United States of America. The practical example is different, but the same principal applies: guest speakers in South Africa will make a big difference.
