HPR1470: Learn to read time with ccClock




Hacker Public Radio show

Summary: Over the years the image of the clock has been abstracted and stylized to a point where a long and a short line inside a circle, or even inside four dots on the ordinals, can be instantaneously recognized as a clock. This is perfectly fine if you already know how to read the analog clock but it makes no sense to use such a design as a teaching aid. As a teaching device, you need to make sure all the information that has been abstracted away has been put back. That is the basic principle of the ccClock The minute hand points at the minute dial All the minutes are listed removing the need to know the 5 or 15 math table The Clockwise direction is emphasized with arrows and text orientation. The two per day rotation of the hour hand is described using a concentric spiral The progression of day into night is indicated by recognizable icons of the rising and setting sun and moon The written format is described in the traditional dial digits The spoken form is described in speech balloons Links Dave Allen - "Teaching Your Kid Time" http://openclipart.org/ http://ccklok.nl/ http://ccclock.com/
