In preparation for C6, and to address the key themes for the second year of CONSTRUIT! (viz. collaboration and instrumentation for analysis), further enhancement of the new CONSTRUIT! environment for making construals will be required. Relevant issues include:

• using tablets as satellite devices in a network potentially centred on a construal hosted on a workstation. This will require reinstating the network remote mechanism to support communication, logging and replay.
• interface issues for the tablet environment - consideration of strategies such as 'tiling'.
• integration of the old and new variants of the CONSTRUIT! environment - how existing construals can be interpreted without any essential change in the new CONSTRUIT! environment, how JSPE presentations can be supported and/or converted to the worksheet-style format.
• translation of existing construals (as partially carried out to date) - to include construals used in C5 (such as jugs, bubblesorting), at SciFest 2015 (Light Box - with some problematic aspect! - and Nim), Peter's examples (Bezier and free sketching), circuit diagram and light in room - both separate and blended, shopping extensions from C14. Also not to be forgotten is the MENACE construal.
  
• new resources to be developed specifically to showcase qualities of the new CONSTRUIT! environment, to include purse / vending machine / giving change worksheets, a reworking of the student workshop from C2, a worksheet based on the iTAG tutorial paper (cf. CAS Local Hub presentation in September 2015), the Clayton Tunnel reworked, interfacing with Arduino.
• video tutorial resources based on e.g. basic use of the CONSTRUIT! environment, the iTAG worksheet(s), the workshops for teachers and pupils at C2.
• object-style prototyping based on scoping (cf. the left arrow illustrative example): resources to explain and further illustrate / develop scoping: consideration of related issues for translation of old tkeden models.
  
• The Abstract Definitive Machine, concurrency and collaboration.
  
• Project management implementation, as discussed at C2.
