Factors That Influence The Difficulty Of Problem Solving Items, Dara Ramalingam, Ray Philpot

Computer-based assessment of problem solving allows problems of both static and interactive natures to be posed. Examples of static problems are scheduling and logic puzzles in which all relevant information is available to the solver at the outset. Problems of an interactive nature, on the other hand, require exploration of the situation to acquire additional knowledge needed to solve the problem. Examples include discovering how to use an unfamiliar mobile telephone or automatic vending machine. This study used data from the 2011 Field Trial of the PISA 2012 computer-based assessment of problem solving which comprised 34 static and 45 interactive …

The OECD PISA 2012 Problem Solving assessment was delivered on-line and exploited the capabilities of the computer by including many problems where students were required to interact with a virtual scenario. The actions taken by students – clicking buttons, dragging objects etc – were recorded in log files during testing. For many items these logs were used to automatically score the item. In some cases the strategy exhibited by the students as they tackled a problem contributed to the scoring, in addition to whether they managed to solve the problem. In this paper I give an overview of the PISA …
