As with all of the other tests listed in this series of “Tests for Non-English-Speaking Persons,” the Addition tests will bring more satisfactory results, with much greater economy of time, if they are administered as group tests. They are here described, however, as tests for individual candidates in order that they may be given to foreign language-speaking candidates without any other apparatus than that furnished by the test booklets themselves. Any teacher or employer who has a number of persons to be examined should prepare a blackboard or wall chart on which to exhibit an enlarged copy of the examples used in the introduction. By placing this at the front of the room in full view of all candidates, the pantomimic instructions here described may be used for non-English-speaking candidates, or simple verbal explanations may supplement them for English-speaking persons. _Directions for Giving Mentimeter 10a._ The examiner, after securing from the candidate his name, address, age, and other pertinent information, should turn the examination leaflet and exhibit, for ten or fifteen seconds, the addition tests which are to be solved. The leaflet should then be turned over to the title page again and attention should be called to the examples appearing on the middle of this page under the heading “Add.” The examiner should point to the first example 2 2 — and placing his pencil on the lower 2 and then upon the upper 2 should seem to hesitate for an instant and then write 4 underneath the line. Looking at the second example 15 3 —— he should place his pencil on the 3 and then on the 5 and, with only an instant’s hesitation, should write 18. Similarly, looking at the third example, 23 25 16, ——— he should place his pencil first on the 6, then on the 5, then on the 3, and write a 4 underneath the line; then place his pencil on the 1 and then upon the two 2’s in order and write 6 at the left of the 4. With this explanation the examination booklet should be opened and a pencil supplied to the candidate with the instructions “Go ahead! Add them all!” MENTIMETER NO. 10A.
