Graphical Representation


1. Explanation

Sometimes small management artefacts help to better planning an evaluation, thus contributing to the quality of the evaluation. The CSCL-EREM proposes a representation diagram that supports evaluators to plan a CSCL evaluation in a practical and contextualized way. This diagram is deeply inspired in the one proposed by Stake (2006) to represent Case Studies. The following two figures show the representation diagrams of two evaluations that follow courses 1st and 2nd respectively. The first one illustrates the representation diagram we used to plan the evaluation of a blended undergraduate course called NNTT on ICT to preservice teachers. More details on the NNTT course are described in Jorrín-Abellán (2007). The representation shows relevant aspects considered within the three facets of the model, as well as a brief schedule of the evaluation according to the data gathering techniques, the informants and the supportive technologies used in the evaluation. The right side of the figure shows the representation diagram of the aformentioned evaluation of Ontool-search (Vega-Gorgojo et al, 2008). Both diagrams represent in the lower right side of the circle the issues that guided the evaluation. These issues serve as conceptual organizers of the evaluation, helping evaluators to focus on the desired tensions of the evaluand. Issues are suggested by the model as "conceptual organizers" for the evaluation study, rather than hypotheses or objectives. An issue can be understood as a tension, an organizational perplexity or a problem.


2. Create your own one

You can create a graphical representation of the planning of your evaluation by using the application below. Here´s a quick-start guide to do it:

  1. Draw basic shapes: Just draw. Dabbleboard will automatically detect basic shapes like straight & curved lines, rectangles, circles, diamonds, and triangles. Make sure the Freehand button is not selected.
  2. Draw freehand: Click the Freehand button to draw anything you like. You can still move and resize objects just like any other shapes.
  3. Enter text: Just click anywhere and start typing.
  4. Select objects: Click on any object to select it, or to deselect it if it´s already selected. To select all objects in a rectangular area, click in any empty space on the canvas to reveal the Select Area button. Click this button to make your selection.
  5. To download and save your design click in Image:Botonguardar.png .
  6. Modify selection: Use the drop-shaped buttons at the four corners of the selection.
