Generating Culturally Responsive Visual Aids for Teaching and Learning
This mixed-methods study demonstrates that a customized AI tool (CReVAG) effectively supports Ghanaian preservice teachers in creating culturally responsive visual aids and enhancing classroom instruction during their practicum, while highlighting the need for guided usage to address technical and linguistic challenges.

Imagine you are a student teacher in Ghana, standing in front of a classroom full of kids. Your job is to explain a tricky idea, but you don't have a fancy projector or a box of colorful posters. You need a visual aid—a picture or a chart—to help the students "get it." Usually, you'd have to spend hours drawing by hand or hunting through the internet for a picture that might look nothing like the students' actual lives.
Enter CReVAG (pronounced like "cray-vag"). Think of this tool as a super-fast, magical sketchbook powered by artificial intelligence. But here's the twist: it's not just any sketchbook. It's been trained to know that a classroom in Tamale, Ghana, looks different from a classroom in New York. It's designed to draw pictures of local markets, familiar clothes, and community activities that the students recognize immediately.
The Big Experiment
Researchers wanted to see if this "magical sketchbook" could actually help student teachers create better lessons. They gave 32 final-year student teachers a special version of this AI tool during their 12-week teaching practice. These teachers had to use it to make visuals for their real classes, and then, experienced teacher educators watched them teach and graded the results.
What They Found (The Good Stuff)
The results were pretty exciting. When the experts looked at the pictures the AI helped create, they gave them high marks.
- Clarity: The pictures were clear and accurate, with a score of 4.44 out of 5.
- Cultural Fit: The pictures felt "at home." They showed local culture and familiar settings, scoring 4.40 out of 5.
- Teaching Help: The pictures actually matched the lesson goals, scoring 4.38 out of 5.
In fact, out of 45 visuals checked, 29 were rated "excellent," 14 were "good," and only 2 were "fair." None were rated "poor."
The teachers who used these AI-made pictures also did a better job teaching. Their lessons were rated highly for how well they used the pictures (4.24 out of 5) and how clear their instructions were (4.27 out of 5). The students seemed more interested and engaged, and the student teachers felt more confident standing in front of the class.
One student teacher said the tool was like a "time-saver," letting them create custom pictures in minutes instead of hours. Another said it made them feel "more prepared and organized." It was as if the AI gave them a boost of confidence, like a training wheel that helped them balance while they learned to ride the bike of teaching.
The Catch (What the Paper Rules Out)
Here is the most important part: The paper is very clear that this AI is NOT a replacement for the teacher.
The researchers found that the AI didn't just magically spit out perfect pictures every time.
- It needs a human driver: If the student teacher asked a vague question like "draw a classroom," the AI might draw something generic or even wrong. The teachers had to learn how to write specific prompts (detailed instructions) to get the right result.
- It makes mistakes: Sometimes the AI drew clothes that didn't match Ghanaian culture, or it struggled to write correctly in local languages like Dagbani.
- It's not perfect: The paper explicitly states that these tools can sometimes show "foreign settings" or "broad African" ideas that don't fit the specific local reality.
So, the paper argues against the idea that you can just hit a button and walk away. The AI is a helper, not a boss. The student teachers had to act as editors, checking the pictures, fixing the errors, and making sure the cultural details were right before showing them to the kids. As one student put it, they would use the tool "alongside my professional judgement."
The Hiccups
It wasn't all smooth sailing. The students faced some real-world bumps:
- The "Prompt" Puzzle: Many students found it hard to write the right instructions to get the AI to do exactly what they wanted. It took practice to learn how to ask for a "market scene in Tamale with women in blue wrappers" instead of just "a market."
- Internet Woes: Sometimes the internet connection was slow or unreliable, making the tool frustrating to use.
- Language Limits: The AI sometimes messed up local languages, which meant teachers had to double-check everything.
The Bottom Line
The study suggests that tools like CReVAG can be a game-changer for teacher training in places like Ghana. They can save time, make lessons more fun, and help teachers feel more confident. But the paper is careful to say this only works if the teachers are trained to use the tool wisely.
Think of it like this: The AI is a powerful paintbrush, but the student teacher is still the artist. If the artist doesn't know how to hold the brush or what to paint, the picture won't be any good. But if the artist knows their craft and uses the brush to add local colors and details, the result can be something truly special that helps students learn.
The researchers didn't prove that this solves every problem in education, and they didn't test if the students' test scores went up. They simply showed that with the right guidance, these AI tools can help student teachers make better, more culturally relevant pictures for their classrooms.
