Teaching with AI video: classroom explainers in Kiswahili and English

Every teacher knows the moment a lesson lands: a pupil who was lost suddenly sees it. Often that moment comes from a picture, a demonstration or a story rather than a definition. For decades, teachers in Kenyan classrooms have drawn those pictures on a chalkboard, borrowed a projector, or described the scene and hoped the class could imagine it.

Short video changes what a teacher can show. And with AI video, a teacher can make a clip for a specific lesson rather than hunting for one online that is almost, but not quite, right.

Where short clips help most

• Processes you cannot see: photosynthesis, the water cycle, erosion, digestion
• Places pupils have not been: the Rift Valley from above, a coral reef at the coast, a Turkana settlement, a city in another country
• History brought to life: a market in old Lamu, the building of the railway, carefully and accurately
• Stories in the language of the lesson: a short scene in Kiswahili for a fasihi lesson, or a dialogue in English for a speaking exercise

Language matters

Pupils learn best in a language they think in. Tari Studio lets you set the language of every spoken line and on-screen word: Kiswahili, English as Kenyans speak it, the Kiswahili-English mix, English (international), French or Chinese (Mandarin). For a Kiswahili lesson, the whole clip can be in Kiswahili, and the words on screen will be too. Ads, and lessons, in the languages people speak.

Start with a script

Type /script in the Studio, the length and what the clip should explain. The AI director writes timed scenes with what we see, spoken lines and on-screen words. Read it as a teacher would: check every fact, simplify where needed, correct any word. Scripts are free. Only when the script is right do you make the video. Scripts with /script.

This is the most important step. AI can get facts wrong. A clip shown to forty pupils must be checked by someone who knows the subject.

Use it as a starting point, not the lesson

A thirty-second clip works best as a hook at the start of a lesson or as a recap at the end. The teaching still happens in the conversation that follows: "What did you see? Why did the water rise? What would happen if...?"

Practical points

• Keep clips short. Under a minute. Attention fades fast.
• Download and play offline. Many classrooms have unreliable internet. Download the finished video from the library and play it from a laptop or phone.
• Do not depict real children without consent. For scenes with pupils, use generated characters, and never imitate a real child.

For schools and edtech teams

Schools and edtech publishers can build a shared library of clips aligned to the curriculum, one per topic, reviewed by subject teachers. It is a resource that improves every year.
