Pictures with narration versus pictures with on-screen text during teaching mathematics

Constraining Pictures with Pictures

This paper presents a visual language called Miro for specifying and restricting operating system security configurations. A Miro picture specifies exactly what rights users have on files. A Miro constraint, also stated visually, restricts the set of Miro pictures which are considered legal. Such constraints on pictures give an exact specification of security policies and a practical method for...

For example, 'text is made up of letters whereas graphics are not', 'one can create text using a keyboard', 'one can read text aloud', etc. However, none of these provides robust condition...

Referring To World Objects With Text And Pictures

It oftcn makes sense to employ both text and pictures wheu referring to world objects. In this paper, we present a model for referring which is based on the assumption that concepts may be activated not only by Icxt, but also by pictures and tcxt-pieturc combiniltious. By means of a case study, we demouslrale that l'ailure aml success of referring acts can be cxplalncd by thc user's ability to ...

Due to its apparent possibility of deducing abstract formulas without the necessity of back-linking to the outside reality, pure mathematics’ status is often experienced as being isolated from and superior to the dubious reality and our evenly ambiguous perception of it. Despite this attitude, several examples...
