HOUSTON, Texas (KTRK) -- After last week's winter storm closed down schools, most districts opted to go virtual on Wednesday. But in Houston ISD, there was a catch. Parents told ABC13 their kids were only required to log in for a short time without any teachers. They add this created a lot of confusion. When we reached with some questions to the district, here's what it had to say in response. Students were told they would only have to log in for about 40 minutes [Wednesday] to complete assignments, yet no teachers. Why was that decision made? "Teachers were provided a teacher preparation day and had the option to return to campuses or work remotely [Wednesday Feb. 24] before returning in person on Thursday, Feb. 25. After our students and their families experienced a very difficult week, we wanted to make sure all facilities were repaired and ready and that students were able to have a smooth transition back to class using virtual asynchronous learning," HISD said.
