Technology Front - In addition to Licensed version or OPEN wares on O.S / APPLICATION / DB., the following work needs to be done.....

Developing the Application; Content development to-be into the Application; Answer KEYS; Evaluation criteria; Access rights; User rights; End User training & Acceptance;

People Front - Plan & Execute a well strategic Change Communication initiative.

In my view, the most challenging issue that arises when applying ubiquitous computing devices to classroom environments is the design of the interaction. More specifically, the design of feedback on the students' work. Hattie (2009) identifies feedback as the most effective single variable in the design of learning environments. My PhD thesis (The potential of a classroom network to support teacher feedback : a study in statistics education; http://irs.ub.rug.nl/ppn/343084066 ) was on this issue.

To me, heterogeneity of terminal devices and ensuring the integrity of the context of content across heterogeneous terminal devices is a challenge that needs attention.

Having impaired students specially in a science class is something that should be highly considered. For Example, much attention should be directed to a visually-impaired student in a physics or mathematics class. Some students may have problems with hearing and communicating with the lecturer. Therefore, if you are developing a ubiquitous system for classroom technologies, this is a matter that you should highly consider.

The classic ubiquitous computing challenges will be applied to this scenario: device heterogeneity, sensor/device communication, context-awareness, ...

In this case, student's "profile" is a key concept if you are trying to adapt/deliver content to student's devices. A very good survey can be find at http://dl.acm.org/citation.cfm?id=2543594

Being a student and researcher from India which consists one of the world's largest domain of education, conducting test and examination in a ubiquitous learning environment is one of the biggest challenges.

As you have asked about the major challenges which could be encountered on implementing ubiquitous computing in classroom learning, my view follows:

1) Students and other stakeholders need to attain a common level of digital literacy and familiarity.

2) Using ICT-based features would deviate the basic goal of education to the goal of being tech-savvy.

3) Prevent cheating in examination is another serious challenge.

4) Even in this advanced age of digitized education, it cannot stand as a comprehensive substitute to the formal education, where face-to-face interaction is a key advantage.
