The main aim of this article is to explore whether pictorial narration could offer a solution to teacher training on the effective inclusion of students with autism spectrum disorder in a low-resource context in the Lao People's Democratic Republic. For this purpose, pre- and post-training knowledge data were collected from 87 Laotian teachers who participated in teacher training using a pictorial narrative e-module called The Story of KhamdyTM. The teacher training included a half-day orientation workshop, followed by 4 weeks of online learning. Statistically significant improvement in autism spectrum disorder knowledge and reduction in autism spectrum disorder stigma was recorded for the teachers after completing the teacher training. The findings on social validity pointed to high acceptance toward the pictorial narrative method and the content designed for the purpose of this training. The teachers' acceptance of the training method was found to have positive effects on their knowledge changes in the diagnosis and etiology aspects of autism spectrum disorder knowledge. The findings supported the use of a pictorial narration approach in imparting knowledge about inclusive education and autism spectrum disorder to teachers in a least developed country. The findings offered insights to explain the knowledge change and stigma reduction recorded.
