A group of Staten Island parents demanded the full reopening of city schools Thursday and pledged to take legal action if Department of Education buildings remain mostly shuttered due to coronavirus fears.

About 50 protesters gathered outside Tottenville High School as the campus launched a hybrid learning format that will have kids alternate between home and classroom learning.

Attorney Louis Gelmormino said he is part of a legal team that will file a class-action lawsuit against the city to force the outright reopening of schools.

“This is our children,” he said Thursday. “This isn’t a restaurant. This isn’t a business. This is our children, and we will do anything we can to fight for our children.”

Gelmormino said that city decision-makers — including Mayor Bill de Blasio and Schools Chancellor Richard Carranza — will not act unless met with legal resistance, calling it “the only thing that these people understand.”

The protesting parents dismissed remote-learning as a shoddy and ineffective replacement of face-to-face instruction.

“It’s nonsense,” said parent Roseann Arena, 34. “Computers don’t teach. They put a 2-minute video on. If you’ve never learned it before, what is a 2-minute video? They’re not learning.”

Erin Ulitto, 34, said her special needs son, Lucca, is fading academically and emotionally due to the lack of live teaching.

“Remote learning does not work for my son,” she said. “He’s 6-years-old in sixth grade with special needs. He’s at a crucial time in his life where he needs those services. He needs in-person therapy. It’s not working. I open the computer, he closes the computer. He runs away. He cries. He screams. It just ends with both of us crying at the end of the day.”

Michele Davita, 45, has three children in Staten Island public schools.

“Not all of these kids are computer literate,” she said. “They want them to go from this slide show to this slide show to this website. My son looks at me and says, ‘Ma, how do I do this?’ I have no idea. These kids don’t know how to do this. They weren’t taught that. And now it’s mashed in their face and they don’t know what they’re doing.”

Davita speculated that the scope of the educational damage being wrought won’t soon be fully realized.

“What kind of education are they giving them?” she asked. “They’re going to be a bunch of failures in a couple of years.”

State Assemblyman Michael Reilly, who has a daughter at New Dorp High School, echoed the call for a full revival of city schools.

“My daughter will attend school once a week,” he said. “Think about that. If they keep us locked down, that equates to roughly, without holidays, 40 in-person school days in 10 months. That is not an education. That is unacceptable. Let’s make sure that we give our families, our students and our educators an option of full time, in-person live teaching in our schools.”

His child, Kate Reilly, 16, said that her classmates are pining for the return of traditional schooling.

“I speak on behalf of every single student I know,” she said. “We miss school. We need school. We miss socializing with the kids. We miss our teachers. We miss class. We miss learning.”

City Hall has only partially reopened city schools, arguing that the coronavirus crisis poses too great a threat to resume full-time classroom learning.

De Blasio has stated the DOE will likely only return to normal with the emergence of a COVID-19 vaccine.

An agency spokesmen argued that ongoing coronavirus threats prevented full-time schooling for city kids.

“This is a distraction from real news: today, we are officially open for in-person learning in every grade, and students will continue receiving high-quality instruction five days a week in a way that keeps our communities safe and helps prevent the spread of the virus,” said Danielle Filson. “As we continue to navigate a global pandemic, our reopening plan prioritizes the health and safety of our students and staff and is in line with guidance issued by federal, state, and local health experts.”
