Abstract

Fixture 10 for paper form 12 directly indicates the student's progress as a test is traversed. Fixture 10 comprises baseboard 14 of insulating material on which a plurality of conductors 16 is laid down in conductive ink. Aperture sheet 20 overlies conductors 16 and underlies paper form 12. The latter is held in place by conventional devices not shown. Form 12 has questions and multiple choice answers printed on the obverse along with indications of points at which the student presses a finger to enter the choice of answer. Conductive ink lines 22 printed on the reverse of form 12 complete elastic diaphragm switches with aperture sheet 20 and conductors 16 on baseboard 14. These diaphragm switches are connected in a two-lamp circuit.

Paper Forms and Fixture for Self Scoring Tests

Fixture 10 for paper form 12 directly indicates the student's progress as a test is traversed. Fixture 10 comprises baseboard 14 of insulating material on which a plurality of conductors 16 is laid down in conductive ink. Aperture sheet 20 overlies conductors 16 and underlies paper form 12. The latter is held in place by conventional devices not shown. Form 12 has questions and multiple choice answers printed on the obverse along with indications of points at which the student presses a finger to enter the choice of answer. Conductive ink lines 22 printed on the reverse of form 12 complete elastic diaphragm switches with aperture sheet 20 and conductors 16 on baseboard 14. These diaphragm switches are connected in a two-lamp circuit. One or the other lamp is lighted in accordance with the choice of reply to the particular question answered. One lamp 30 is for incorrect answers and the other lamp 31 is for correct answers.

Fixture 10 carries cover frame 34 which overlies baseboard 14 and allows the central portion of form 12 to be viewed by the student. Dial device 40 is attached to frame 34 overlying a pair of apertures through which lamps 30 and 31 can be seen. Dial 40 comprises two sections 42 and 44. Upper section 42 is free to move in either a clockwise or counterclockwise direction. Lower section 44 is held by detent dog spring 46 so that it can move only counterclockwise. In this manner, there is a differential...
