9 2. Advantage and disadvantage of each display 9

10 Tabletop + flexible user arrangement + known from table + on-task communication - risk of interfering each other Source: 10

11 Interactive whiteboard + same perspective + focused time-efficient + maintain awareness of activities - viewer in front - not enough place for real collaboration - reaching problems possible Source: 11

12 Desktop computer + on-task communication essential - one-user, one-display paradigm - older students feel socially uncomfortable Source: 12

13 Mobile devices + control from anywhere + individual devices / workspace Source: 13

14 Multi display environments + combine advantages + individual workspace - distraction possible Source: 14

15 3. Which display for which task? 15

16 Exploratory Study (Kori Inkpen et al.,2005) - 48 participants - four display factors: angle user arrangement display size number of displays Source: 16

18 Tabletop - two or more people gather around tabletop - on-task communication to solve task Task: Solve exercise together Application (for example): DigiTile Source: 18

19 Interactive whiteboard - everybody sees everything of the data Task (for example): Collaborate creating Source: 19

20 Desktop computer - most uncomfortable way of CSCL Task: Getting children introduced to CSCL Source: 20

21 Mobile devices - bring seperate data together (whiteboard) Task: include students in lesson design Application (for example): KidStory, ImageMap Sources: (right) 21

22 Multi display environments - individual workspace + public board Task: like mobile devices, but more possibilities Application (for example): GroupScribbles Sources: (right) 22

23 4. Summary 23

24 - two or more users shared display - displays are flexible - all types together can't be allocated to certain tasks use collaborative learning to full capacity 24
