Action on angles
ANGLE, from Chalksoft, is a package of four programs which go
together in pairs - a demonstration program and a program where
the new knowledge is put into practice.
The first demonstration program measures angles as fractions
of a turn, relates these fractions to degrees and then estimates
angles in terms of degrees.
The second demonstration program shows how to use an angle indicator
(a protractor to measure 360 degrees).
Angles are drawn and the angle indicator superimposed.
The angle is then read off the scale. Both programs are clear
and helpful, the second particularly so.
Each contain sufficient examples to put the points across clearly.
The interactive programs use the knowledge learned from the
previous program and there were no ambiguous questions.
Unfortunately there is no help if the wrong answer is given.
This package is most useful in the classroom. The development
of the content is well thought out and works well in practice.
The use of graphics is excellent throughout.
