University students increasingly watch animated math videos that use dynamic visualizations as part of their learning process. Despite students' positive appreciation, little is known about how these visualizations contribute to learning outcomes. This paper examines the relationship between learning outcomes and students' experiences with dynamic…

Avatars play a significant role in Artificial Intelligence (AI)-powered education, supported by various human-computer interactions and second language acquisition theories. AI avatars have become increasingly anthropomorphic and realistic with advancements in speech synthesis, speech-driven lip-syncing, and speech-to-facial animation. D-ID Studio…

This study investigates the impact of different animation styles on learning outcomes in physics, with a focus on explanations of the seasons. Using a combination of pre-post performance tests and eye tracking, we compared animations featuring a presenter with pure animations without a person in the frame. The sample consisted of students from a…

Vaccine hesitancy was recently declared one of the ten greatest global health threats by the World Health Organization and research has linked it to low levels of health literacy. Health literacy can be supported by media literacy education which aims to heighten critical thinking and help individuals develop habits of inquiry and make appropriate…

In recent years, a multitude of innovative educational videos focusing on mathematics and employing dynamic visualization techniques have been published on YouTube. From a sample of videos, we develop a taxonomy of didactical roles of dynamic visuals and supporting animation techniques. The taxonomy is constructed through an open coding approach,…

This article describes the motivation, aims, and consequent processes involved in designing an engaging and informative animated educational video that explains the historical exploitation of the Mount Dagushan iron ore mine in China. The mine is recognised as the deepest in China. It has been the source of raw material for the Anshan Steel…

D-ID Creative Reality Studio (D-ID) is a platform for creating Artificial Intelligence (AI) presenter (digital human) videos, translating videos, and designing conversational agents. D-ID seamlessly integrates deep-learning face animation technology, large language models (LLMs), natural language processing (NLP), and speech synthesis and…
