  1. Delivery platforms for national and international computer-based surveys History, issues and current status Sam Haldane Australian Council for Educational Research (ACER)

  2. PISA CBAS Objectives Comparability translation rich content Requirements Security Hardware, software Test Administrator knowledge

  3. CBAS - Implementation Installed client / server software Java Java Media Framework (movies and sounds) Internationalization / localization support Networking Hardware platform Client / server carry-in laptops + network

  4. CBAS - Economics Delivery – carry in laptops = high cost and low failure rate Data capture – data management procedures Marking – not required due to nature of items Ease of translation Low word count Must install custom software Translation of interactive elements

  5. PISA ERA Objectives Lower cost Logistically easier Use existing school infrastructure Comparability not so important Complex hypertext environment

  6. PISA ERA Requirements Cannot assume inter / intranet Cannot assume host OS version Cannot always install software Must run on lowest common denominator hardware

  7. PISA ERA Implementation Bootable CD with USB storage in field trial Bootable USB option in main survey Linux OS using TAO as delivery platform CD / USB contains all software needed (server, browser, Flash etc.) Minimum possible hardware requirements Need for TA to change boot order in BIOS

  8. ERA - Economics Delivery – using existing school infrastructure = low cost but high failure Data capture – de-centralised on USB storage – data management logistics Marking – expert marked items, need for online marking software Translation – need for separate translation system, and localization of marking system

  9. NAP – ICT Literacy Assessment Commissioned by MCEETYA1 Australia wide assessment of ICT literacy in year 6 and year 10 (12 and 16 years old) Measures ability to use ICT appropriately to access, manage, integrate and evaluate information develop new understandings communicate with others in order to participate effectively in society 1 Ministerial Council on Education, Employment, Training and Youth Affairs

  10. NAP – ICT Literacy Assessment Three deployment models Internet delivery – school computers used as clients with remote server Carry-in server – school computers used as clients, with server laptop plugged into school LAN Carry-in minilabs (10 machines) – same model as CBAS, for less equipped schools High success rate - 99% school-level response rate after replacements

  11. NAP – ICT Literacy Assessment Technical issues Remote desktop client requires non-standard port Internet Explorer plugin requires installation, and Windows OS TA training for all three deployment models Schools requiring minilabs usually remote

  12. CBAS vs ERA Carry-in laptops vs bootable CD / USB Comparability issues – ERA hardware differs greatly whereas CBAS was standard High failure rate in ERA, perhaps more so in some schools

  13. The future Toolbox of delivery methods that are used depending on school infrastructure Internet delivery will have highest ROI – ease of deployment, administration costs, but lack of infrastructure

  14. The future No silver bullet Carry-in server model best trade off at the moment Remote desktop based solution (for some projects) Interactive content with Flash Ajax – Google Apps possible future direction
