Reading an analog clock is typically hard for young learners in primary school as well as for people suffering from dementia.[1] In Decoding the Disciplines it often serves to exemplify the process of Decoding.[2]
Description of bottleneck
People find it hard to read of the information coded by the hands of a clock and translate this information into a valid description of clock time.
Description of mental tasks needed to overcome the bottleneck
- There are two scales on an analog clock. A coarse one counting from 1 to 12 in steps of 30° and a finer one counting from 0 to 59 in steps of 6°.
- If there is a fast moving hand, ignore this one for the time being, although it typically catches one's attention first.
- To determine the hour, locate hour hand. This is usually the smallest hand. Read the position of this hand on the scale from 1 to 12. If the hand is between two such position take the smaller value.
- To determine the minutes, locate minute hand. This is usually the larger hand. Read the position of this hand on the scale from 0 to 59.
- If there is a fast moving hand, it indicates the seconds analogously to the minute hand.
