Argumentation, a key scientific practice presented in the "Framework for K-12 Science Education," requires students to construct and critique arguments, but timely evaluation of arguments in large-scale classrooms is challenging. Recent work has shown the potential of automated scoring systems for open response assessments, leveraging…

High-quality science assessments are multi-dimensional. They promote disciplinary practices, core ideas, cross-cutting concepts, and science sense-making. In this paper, we investigate the feasibility of using generative artificial intelligence (GenAI), specifically multimodal large language models (MLLMs), to annotate and provide improvement…

The point of Choi and Clark (2006) was that after many well-designed studies, they have no evidence for either the learning or the motivational benefits of pedagogical agents. In their study, they found compelling evidence that when agents are found to enhance learning, a less expensive and less distracting pedagogical method has equal or greater…

Choi and Clark (2006) argue that learning is attributed to the instructional method rather than the specific medium used to deliver instruction (i.e., the pedagogical agent). Additionally, they consider pedagogical agents as unnecessarily expensive tools, whose instructional affordances can be replicated by less expensive options. In this response…
