Educators see the damage already. The Learning Consultants has 50 plus tutors throughout Connecticut and New York. Many are teachers. The anecdotal evidence is unsurprising: students are falling behind.
The reasons are easy to decipher: there has been less school (those hybrid models usually deplete the school day); more time for unhealthy diversions (Tik-tok, social media, and video games not reading have increased), and far less effective teaching.
