基于位置感知的移动学习应用越来越多，然而，关于它可能如何影响协作中的社会认知过程的信息仍然缺乏。这就是下面的实证研究旨在解决的问题。我们使用了一款在平板电脑上运行的移动协作游戏来测试两种情况。在一个实验条件下，小组可以看到每个成员的位置；而在另一个实验条件下，没有提供位置感知。所有用户都可以使用Tablet PC通过注释进行交流。我们发现两种条件在任务绩效上没有差异。在认知工作量方面也没有任何差异。然而，没有位置感知指示的玩家更好地代表了他们合作伙伴的路径。他们写了更多的信息，更好地阐述了自己的战略。文章最后对移动学习从业者如何考虑这一点进行了评论。
There is an ever growing number of mobile learning applications based on location-awareness, However, there is still a lack of information concerning how it might impact socio-cognitive processes involved in collaboration. This is what the following empirical study aimed to address. We used a mobile and collaborative game, running on tablet PCs, to test two conditions. In one experimental condition, groups could see the positions of each member; while in the other location-awareness was not provided. All users could use the tablet PC to communicate through annotations. We found no differences between the two conditions with regard to the task performance. Neither were there any differences in terms of cognitive workload. However, players without the location-awareness indications had a better representation of their partners' paths. They wrote more messages and better explicated their strategies. The paper concludes with remarks about how this can be taken into account by mobile learning practitioners.
