BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention;

In FIG. 1, reference numeral 1 denotes a learning teaching tool according to the present invention, and the learning teaching tool 1 displays a table at equal intervals in the longitudinal direction of the surface of a base 2 having a planar square shape. A question display section 3 is formed, and an answer display section 5 on which a plurality of answers 4 including correct answers are displayed is provided on the right side of the question display section 3. The base 2 is preferably formed of a synthetic resin, but is not necessarily limited to this, and may be, for example, a cardboard or a board. Further, the question display section 3 is not limited to the multiplication table, but may be a chemical formula, a calculation formula, or the like.

A plurality of answers 4 including correct answers displayed on the answer display section 5 are covered with a polarizing filter 6 and the polarizing filter 6 is covered on a correct answer 4. Those having the property of transmitting only light having a longitudinal vibration direction have the property of transmitting only light having the transverse vibration direction, while those covered on the wrong solution 4 have the property of transmitting light. When the answer display unit 5 is covered with the polarizing filter 6, the plurality of answers 4 including the correct answer displayed on the answer display unit 5 can be viewed from above the polarizing filter 6.

Note that the polarizing filter 6 covered on the solution 4 is not limited to this, but may have a property of passing only light having both completely opposite vibration directions. .

Guide rails 7, 7 are provided in the upper and lower portions of the surface of the base 2 in the lateral direction, and a sliding member 8 is movable between the guide rails 7, 7 in the lateral direction. Has been overtaken. A guide groove 9 is formed in the sliding member 8, and a movable piece 10 is attached to the guide groove 9 so as to be vertically movable. Further, another polarizing filter 11 is fixed to the moving piece 10 and the polarizing filter 11
Is the movement of the sliding member 8 in the lateral direction and the moving piece 10
Answer 4 in the answer display section 5 by moving the
Polymerized on all polarizing filters-6 covered on the
Can be separated.

The polarizing filter 11 has a property of transmitting only light having a vertical vibration direction, similarly to the polarizing filter 6 covered on the correct solution 4.

Since the learning teaching tool 1 is constructed as described above, one of the question display sections 3 of the multiplication table displayed on the surface of the base 2 is selected for use. For example, a 4 × 5 question display section 3 is selected. After considering or answering the answer, the polarizing filter 6 covered on the answer display section 5 on the right side of the question display section 3 on which the plurality of answers 4 including the correct answer are displayed is provided. Moving member 8 and moving piece 10
Is moved, and the polarization filter 11 fixed to the moving piece 10 is superimposed, so that only the correct answer 4 appears and the erroneous answer 4 becomes invisible.

As described above, according to the learning teaching tool 1, it is possible to know the correct answer by a simple operation of simply superposing another polarizing filter 11 on the polarizing filter 6 covering the answer display section 5. In addition to being able to do so, the structure is very simple and the cost can be kept low.

Next, FIG. 3 shows another embodiment of the learning teaching tool 1. In this example, the learning teaching tool 1 is provided with several multiplication formulas approximately at the center of a base 2 having a planar square shape. Is displayed, and an answer display section 5 on which the answer 4 is displayed is provided on the right side of the question display section 3.

The question display section 3 has a multiplicand of 3 at the top.
The multipliers located at the lower part are 4 and 6 at the lower part, and the multipliers located at the upper part are 8 and 2 at the lower part. The question display section 3 on which the multiplicand and the multiplier are described is configured as shown in FIG.

That is, a polarizing filter 15 having the property of passing only light having a lateral vibration is covered on the mount 14 on which the number 3 is written, and the number 8 is written. A polarizing filter 17 having a property of transmitting only light having a vertical vibration is covered on the mount 16. The mounts 14 and 16 are cut into strips at equal intervals in the horizontal direction, and the cut mounts 14 and 16 are alternately arranged from above and fixed by appropriate means, so that the problem display section 3 Is formed. It goes without saying that the combination of numbers can be freely selected. Also, a combination of three or more numbers may be used.

In the normal state, the number of the multiplicand and the number of the multiplier are not accurately displayed and cannot be visually recognized. Then, as shown in FIG. 5, a polarizing filter-1 that passes only light having a lateral vibration thereon.
By superimposing 8, only the number 3 clearly appears, and by superimposing the polarizing filter 19 that allows only light having vertical vibration to pass, only the number 8 clearly appears. The polarizing filters 18 and 19 can be used in two ways by rotating them by 90 degrees. In using the learning teaching tool 1, two polarizing filters are used.
The correct answer formula may be created by superimposing the polarizing filters 18 and 19 on the problem display unit 3 using 18 and 19, searching for the number of multiplicands and the capitals of the multipliers for which the answer is 6, and forming the correct answer. In this case, when the multiplicand is 3, a correct formula having a multiplier of 2 may be formed, and when the multiplicand is 6, a correct formula having a multiplier of 1 may be formed.

In this embodiment, the same effects as described above can be obtained.

In this embodiment, the same reference numerals as those in FIGS. 1 and 2 denote the same parts, and a description thereof will be omitted.
