KATHMANDU, Feb 27: If your children are studying in Grade 10, then you should be aware that their curriculum is teaching them incorrect history. The contextual lesson on page 243 of the Nepali subject textbook for Grade 10 contains content from a letter supposedly written by the former President of America, Abraham Lincoln, to the principal of his son’s school, titled ‘What will my son have to learn’. Despite Lincoln never having written such a letter, the new curriculum includes this flawed content in the textbook.
