The phonological loop is a component of working memory model that deals with spoken and written material. However, instead of all information going into one single store, there are different systems for different types of information. The Working Memory Model (Baddeley and Hitch, 1974)

Therefore, whereas short-term memory can only hold information, working memory can both retainin and process information.įig 1. This means it is a single system (or store) without any subsystems. Whereas working memory is a multi-component system (auditory, and visual). However, as a result of this research, it became apparent that there were a number of problems with their ideas concerning the characteristics of short-term memory.īaddeley and Hitch (1974) argue that the picture of short-term memory (STM) provided by the Multi-Store Model is far too simple.Īccording to the Multi-Store Model, STM holds limited amounts of information for short periods of time with relatively little processing. Working memory theories assume that complex reasoning and learning tasks require a mental workspace to hold and manipulate information.Ītkinson’s and Shiffrin’s (1968) multi-store model was extremely successful in terms of the amount of research it generated.Working memory is important for reasoning, learning and comprehension.Working memory is a multi-component system which includes the central executive, visuospatial sketchpad, phonological loop, and episodic buffer.Working memory is a limited capacity store for retaining information for a brief period while performing mental operations on that information.For a complete description of parent/child relationships between objects in Sketchpad, see the Sketchpad Help system article Home: Elements: Objects: Object Relationships: Parents and Children. For example, a midpoint is a child of a segment, and a segment is in turn a child of the two endpoints of the segment. (*) Any object that is dependent on another object for its position or value is called the child of that object.

For a full list of objects supported by the current version of JavaSketchpad, refer to the Developer's Grammar. A collection of these workarounds and some tools to help you workaround JavaSketchpad limitations are described in the bottom section of the JSP Authoring section on the JavaSketchpad Links page. These are the objects that the current version of the JavaSketchpad applet does not support.įor many unsupported objects, there are various workarounds available. When you get the Sketchpad warning message this time, only unsupported objects will be selected (and nothing else, since you deleted the children of those objects).

Choose File | Save As HTML to export your sketch again.

Now your sketch contains only objects that can be exported, and the unsupported objects that were the parents of the children you just deleted.

Choose Edit | Clear or hit the Delete key to delete those children.

Choose Edit | Select Children so that your selection contains only objects that are children of objects that were unsupported in your sketch (and their children, etc.).

To identify the exact objects which are unsupported: (These objects have been selected.)" In fact, both the unsupported objects and their children(*) are selected. If your sketch contains objects that JavaSketchpad doesn't support, Sketchpad warns you when you export your sketch by putting up the message "Some objects in this sketch are not supported by this version of JavaSketchpad, and will not appear in your applet. While this set grows and changes with new releases of JavaSketchpad, in general, the applet supports fewer mathematical constructions than the desktop software. Why?Īs a lightweight Java applet, JavaSketchpad supports only a small subset of the mathematical functions and capabilities of The Geometer's Sketchpad. FAQ: JSP Export When I export my Sketchpad document to JavaSketchpad, I get a message saying some objects are not supported.
