Richard Appiah Akoto, from Kumasi uses his blackboard to meticulously draw a diagram of the Microsoft Word program. To be fair the blackboard never blue screened and in some cases might have been quicker.  It also would not be infected by a macrovirus.

Writing on Facebook, Akoto said that teaching of ICT in Ghana is really funny. After the pictures went viral Microsoft promised to send him new computer equipment.

Akoto  wrote: "I love my students so have to do what will make them understand what [I] am teaching."

Quartz said Akoto's school had not had any computers since 2011, despite the requirement for teenagers to pass an information and communications technology (ICT) exam as part of their progression to high school.

Many expressed admiration for his dedication when his mid-February post spread on social media.

"This is not my first time [of drawing] it. I have been doing it anytime I am in the classroom", Akoto told Quartz.

"I like posting pictures on Facebook so I just felt like [sharing it]. I didn't know it would get the attention of people like that", he said.

On Sunday, entrepreneur Rebecca Enonchong tweeted to Microsoft Africa, highlighting that he was teaching the use of their product without actually having access to it.

"Surely you can get him some proper resources", she suggested.

On Tuesday, the software giant pledged to send Akoto a computer and give him access to its education material.
