Teachers TV programmes will only be shown on the internet from August 31 - despite research suggesting that viewers are reluctant to change the way they watch the channel.
The move has been budgeted to save #163;1 million a year. Numbers downloading from the Teachers TV website or viewing programmes online have risen by 42 per cent in recent years.
Teachers TV chief executive Andrew Bethell said: "The savings made by the move online will allow us to invest further in video content and in useful interactive continuing professional development resources that help the whole education workforce to be as effective as possible."
But Government research last year, carried out before the decision to pull the plug on the digital TV channel, found 70 per cent of teachers were still using the TV channel on a regular basis and they were "resistant" to change.
Around 30 per cent only watch Teachers TV on the digital channel, 30 per cent only use it online and 40 per cent use both.
"Given the busy, pressurised and ever-changing environment in which teachers felt they worked, they were very resistant to change ... particularly one which involved learning new technologies or new ways of doing things," the report said.
"Most respondents ... resisted changing their perceptions and use of it as they were concerned about the time it would take, and were reluctant to learn yet more new ways to use technology for their work."
