(this chapter will be finished before 1/3/07 and will form the basis of an article) In this chapter we will give criteria for ICT tools for assessment. Based on these criteria an ICT tool will be chosen for the first prototype. This is our method:
First we compiled a large list of criteria, based on our theoretical framework and own experiences;
From this list we extracted some minimal requirements and categoriesof requirements;The categories were determined by collecting all possible criteria from the theoretical background, grouping them and reformulating a category;
A large list if tools was compiled, based on experiences from earlier projects, the Special Interest Group Mathematics ‘toetsstandaarden’ working group {Bedaux, 2007 #160}, KLOO research {Jonker, #22}, the FI math wiki on digital assessment and math software (http://www.fi.uu.nl/wiki/index.php/Categorie:Ict), and google searches. As there are hundreds of math tools an initial selection was based on the tool having at least some characteristics of tools for assessment. Based on these requirements we:
First selected tools that met the minimal requirements. Tools that didn’t, were described but not considered any further. For this we used a template.
Then the remaining tools were graded on the other categories by:
Using the tool with already existing content. We aim at using quadratic equations as this tends to be subject that is catered for almost always;
Authoring our own content from chapter 5. Here it is possible that not all the finesses of a tool become apparent. A minimal requirement is that authoring can be used. This means for most tools that they have to be installed. For every installed tool I keep a log of screenshots.
This resulted in a separate descriptions of the tools and a matrix, giving an overview of strong and weak points of several tools.
The descriptions of the tools that were considered but did not meet the minimal requirements can be found in appendix C. Descriptions of the tools that did meet the minimal requirements can be found in appendix D. A comparative matrix assessing the strong and weak points of these tools can be found in appendix E. In the long term we aim to publish these assessments in a wiki type environment so they can be kept up to date.
Based on these results we choose tool X because:
Argument 1
Argument 2
Argument 3
Now we will use tool X to model the questions from chapter 5.
