Abstract
Advances of handheld devices such as a PDA afford learners to conduct synchronous discussions and individual ideas made in a group could be synthesized easily. To achieve effective group learning in the classroom, we proposed a PDA-based English vocabulary acquisition game entitled Wireless Crossword Fan-Tan Game (WiCFG) that facilitates English vocabulary building for constructive learning environment. A Cooperative-Competitive module is embedded into this sharing construction learning environment. It is our hope that the game will facilitate students' learning motivation and have much fun. © 2008 IEEE.
