Developing a Project-Based CALL Environment with Technical Communication in an Exploratory 3D Printing Context

Involving EFL students in 3D printing in a language classroom introduces the idea of project-based CALL, where different technology interfaces engage students in complex technical writing activities and social interactions in a fluid language-learning environment. This paper took an instructional approach to explaining how project-based CALL environment could be created with 3D printing based practices, combining technical communication with systems thinking, online research, 3D scanning, computer-aided design, sketch boarding and concept mapping, prototyping, and digital content management. Class performance in this collaborative, autonomous and social language-learning environment suggested that students were able to produce technical writing, prepare documentation, demonstrated critical thinking and brainstorming, and develop design and implementation strategies while handling 3D printing-enabled processes. Results and patterns of student engagement with technology indicated that project-based learning (PBL) approach in TC classroom is engaging, unique, realistic and feasible.
