In the old days, when schools wanted to communicate with parents, they sent a letter home. Now, in addition to email, schools and parents can connect through social media like Twitter, Facebook and Skype. The Houston Independent School District in Texas has more than two hundred thousand students. Most of them come from lower-income families. Education Week recently reported on a digital literacy training program that the district has just started for parents. The school district with help from Microsoft has established computer training centers for parents at five of its campuses. Other schools around the country are also increasing their digital services and not just in English. Many schools provide information in Spanish and other languages. Free online translation sites can also help parents stay informed about their children s education. Some school systems also give parents online access to their children s grades and school work. Six hundred students attend Knapp Elementary School near Philadelphia, Pennsylvania. Principal Joe Mazza says almost one in five students come from Bangladesh and twelve percent from South Korea. The school diversity is clear as soon as visitors enter the building. ' So if you are walking in our school lobby, you are going to see English, Bengali, Korean, Spanish and all of the Finnish in the school. Now we feel that a welcoming, bright, informative, child-centered lobby really helps parents feel welcomed, honored and respected.'
