What are interactive multimodal learning environments and how should they be designed to promote students' learning? In this paper, we offer a cognitive-affective theory of learning with media from which instructional design principles are derived....
Introducing social cues in multimedia learning: The role of pedagogic agents' image and language in a scientific lesson
Introducing social cues in multimedia learning: The role of pedagogic@agents' image and language in a scientific lesson (1999) pp. 1–162
The present dissertation tested the hypothesis that software pedagogical agents can promote constructivist learning in a discovery-based multimedia environment. In a preliminary study, students who received a computer-based lesson on environmental...
Cognition and Instruction Vol. 17, No. 3 (1999) pp. 215–48

Journal of Educational Psychology Vol. 94, No. 1 (2002) pp. 156–63
Three studies investigated whether and under what conditions the addition of on-screen text would facilitate the learning of a narrated scientific multimedia explanation. The overall pattern of results can be explained by a dual-processing model of...
Journal of Educational Psychology Vol. 94, No. 3 (2002) pp. 598–610
College students learned about botany through an agent-based multimedia game. Students received either spoken or identical on-screen text explanations. Results reveal that students scored higher on retention, transfer, and program ratings in...
Learning and Instruction Vol. 12, No. 1 (2002) pp. 107–119
Computer-based multimedia learning environments — consisting of pictures (such as animation) and words (such as narration) — offer a potentially powerful venue for improving student understanding. How can we use words and pictures to help people...
