The individual to be tested should be seated at the left side of the examiner at a convenient table. The examiner should show the inside of the test blank to the candidate and should then point to the similar figures in the explanation on the title page of the booklet. He should then point to the large figure in the first example, possibly tracing its outline with his pencil. Then the attention of the candidate should be called to the parts appearing on the left-hand side. (Their outlines may be traced if it seems desirable.) Next, a movement should be made with the hand as though one were placing the parts upon the larger figure. This may be repeated two or three times, pointing first to the various parts in order and then to the large figure with a rather broad sweep of the hand. After such a study of the situation, the examiner should draw the proper line and exhibit a smile of pleasure at having successfully done the thing. He should point then to the parts of the large figure which are thus created and by jumping his pencil from one of the parts to the corresponding part on the left, he may fairly clearly demonstrate that he has constructed, by his line, elements which are similar to the elements appearing at the left.
Similar pantomime may be used for the second example, possibly introducing a variation by getting a line incorrectly drawn at the first trial, erasing it as soon as it is apparent that the parts do not correspond exactly with the parts appearing in the problem, and redrawing the line so that the correspondence will be exact. The pencil should then be handed to the candidate and the pamphlet opened up for him to begin work. The candidate should be allowed to work for four minutes with occasional signals to “Go ahead,” “Work fast” or “Hurry up.”
_b._ As a group test for illiterate candidates.
A blackboard containing the two examples should be placed in full view of all the candidates in the room. The test blanks should be passed to the candidates, with well-sharpened pencils or pens and ink. The examiner should then hold up in full view of the group a test blank showing the three pages of figures on which they are to work. He should then get the attention of everyone to the work by saying “Look” or “Watch.” With a piece of chalk, he should then go through the pantomime described above for giving the examination to an individual. Care should be taken that none of the brighter candidates begins work before the signal for everyone to work. When the two examples have been thoroughly demonstrated on the blackboard, the examiner may turn to the group, open up his test blank, and point to the first page of work to be done and say, “Begin here,” “Go ahead,” “Work fast.” At the end of four minutes, he should call “Stop,” should collect all papers, making certain as he does so that some identification mark is present on the paper to show to which candidate it belongs. No special explanation should be given and no person in the group should be allowed to sit idle while the examination is going on. If it is clear that the individual has not understood, the examiner may say, “Do what I did,” pointing to the board and then to the paper. Individuals may be told during the course of the examination, if they seem to be doing nothing, to “Make your marks.”
