Researchers suggest that solving ill-structured problems using project-based learning approaches is one way to engender STEM learning outcomes. However, project based learning poses unique challenges in practice, including the translation of technical information, design of scenarios, facilitation of instruction, and management of student collaborations. This process is often time-consuming and inefficient for teachers. To address this issue, virtual internship author is a learning environment designed to support the design, development, and facilitation of STEM based project-based implementations. Specifically, the software is designed to scaffold (a) the instructional design process and (b) the facilitation of project-based learning. The software thus supports multiple stakeholders required for a successful project-based learning initiative, such as subject-matter experts, teachers, and students. Furthermore, the software employs unique strategies, including pre-scripted feedback, conversational agents, and latent semantic analysis to scaffold open-ended discourse during collaborative problem solving. Implications for practice are also discussed.
