- TECHNOLOGY EXPO-The LISD Technology Department hosted a Technology Expo earlier this evening to end our focus on CTE Month. A big crowd came out. LISD educators and students showed parents all the things that they are learning through technology, all the things they can do with technology, and all the things that technology is doing to help them be successful after high school.
