DESCRIPTION:Various research conducted currently on computer multi-touch t
 echnologies involve work environments such as collaborative meeting interf
 aces (Scott et.al 2002\; Widgor et.al 2006)\, which enables visualization\
 , shared displays\, document sharing (Karahalios and Berstorm 2006\; DiMic
 co 2005\; Borchers et.al 2006)\, organization of content (Rekimoto and Sai
 toh 1999\; Shahram et.al 2003\;Crabtree et.al 2008\; Lindley et.al 2008) a
 nd group decision making. Current study in this area does not involve visu
 al cognition principles embedded in the multi-touch environment for educat
 ion applications. This means that teachers find it difficult to determine 
 whether learners are truly undergoing effective collaborative learning. Mu
 lti-touch tabletops that has embedded the functionality to conduct an effi
 cient user identification capabilities are also still relatively new tools
  that have not been fully investigated. Therefore\,this research will inco
 rporate findings of the previous research on cognition and multimedia inst
 ructional design for learning into the development of the prototype called
  Mi Tabletop™ to create a novel approach to display text\, multimedia\, 
 augmented reality inputs on a horizontal interactive surfaces\, using a co
 mbination of strategies and devices to resolve the inherent difficulty of 
 using the conventional monitor and keyboards for collaborative learning pu
 rposes.The idea is that with the use of an interactive multi-touch tableto
 p\, it provides a testbed for exploring the very foundations of education 
 and communication in problem solving during collaborative learning. This m
 ulti-touch tabletop (Mi Tabletop™)  provides a fluid interaction and mea
 ningful multi-display of content to become the users’ true cognitive pro
 sthesis (substitute for eyes etc)\, based on visual cognition principles. 
 Such visual cognition environment is suitable for applications used for co
 llaborative learning\, where knowledge can be extracted easily through the
  multi-touch environment for presentation of information\, brainstorming a
 nd  group decision making essential in collaborative learning process (Hal
 imah 2010\; Riaza & Halimah 2010). However\, this paper highlights the use
  of the visualization tool (Mi Tabletop™) embedded in the multi-touch ta
 bletop to evaluate individual students in small group collaborative learni
 ng experience based on the  learning material called ‘Digital Mysteries
 ’ (Kharrufa et al. 2009)\, which was specifically developed to investiga
 te the use of multi-touch tabletops in a face-to-face collaborative enviro
 nment. Digital Mysteries was designed to be used on the multi-touch tablet
 op prototype that uses Tangible User Interface (TUI) that is the multi-pen
  that looks and feel like the normal pen. Qualitative and Quantitative ana
 lysis based on student trial videos were conducted based on their work log
 s. Criteria that could be visualized to reflect students’ ‘cognitive
 ’ behavior were tracked by the tool as well as teachers (with educationa
 l psychology background) to see if the findings matched at the end of the 
 trials. This would indicate the effectiveness of the visualization tool.
