简介：目前,越来越多的商学院利用仿真技术培养学生的各种能力。而现有的研究对学生在商业仿真过程中,学生如何学习、决策以及这种"learningbyplaying"模型本身的理论框架关注较少。由北京大学研发的BizSim游戏是为学生提供了一个商业竞争仿真的创新平台。基于BizSim平台的全国商业竞争模拟大赛为学生提供了学习商业技能的竞争环境。通过BizSim平台和商业模拟大赛,我们收集了学生参加比赛时的决策数据,并对国内专家、学者和参赛选手进行深度访谈,利用实证性研究方法对数据进行分析。探索在竞争环境下学生学习商业技能的模型和这种商业技能学习模型的基础框架理论。研究发现,在参与式竞争环境中,通过仿真游戏进行商业技能学习的学生,将会在未来的职业发展中更具竞争力和创造力。这种"learningbyplaying"的模型为解决商学教育中所面临的技术和教学的挑战提供了新的一种创新途径。
