The　efficient　and　effective　cooperation　among　the　members　of　a　virtual　team　is　highly　dependent　on　information　sharing　quality.　In　practice　the　accurate　evaluation　is　an　important　premise　to　improve　information　sharing　quality.　In　this　paper,　ten　quality　factors　of　information　sharing　are　introduced,　a　specific　and　operational　evaluation　model　is　conducted,　which　can　be　used　to　evaluate　and　analyze　the　information　sharing　quality.　As　an　example,　the　model　is　employed　to　evaluate　the　information　sharing　quality　of　the　international　courses　BOHKNET.　The　results　based　on　the　analysis　present　the　feasibility　and　usability　of　the　model.　Additionally,　several　suggestions　are　provided　for　the　improvement　of　information　sharing　quality　in　virtual　teams.　©　2008　IEEE.
