Robert Litt advocates open-source software even for schools that arenâ€™t lacking technology. US government reports say the digital divide is shrinking, at least in schoolsâ€”97% of teachers have at least a single computer in the classroom. Yet thatâ€™s not the whole story. â€œThe digital divide is growing in a hidden statistic,â€ Litt says, â€œthe actual teaching of technology in a meaningful way.â€ He shows students how to do math on spreadsheets, how to make simple websites, how to put together slide presentations, all on free software. These are the computer skills that, students tell him, they are later expected simply to know. And with the prevalence of recycled computers, thereâ€™s no need for even 3% of classrooms to be without computers.
