Problems solved by technology

[0002] In the teaching of advanced mathematics, especially in the teaching of calculus, etc., it is necessary to practice repeatedly for students, and appropriately ask some difficult questions to check the knowledge mastery of students. At present, the commonly used method is that teachers use A4 paper in advance Print out the questions and send them to the students, which is a waste of paper, but if the teacher writes on the blackboard, it will waste time because the questions are long, so this question making device is designed

specific Embodiment approach 1

[0020] Specific implementation mode one: as Figure 1-8 As shown, this embodiment describes a random questioning device for advanced mathematics teaching, including a housing 1, a pushing device I2, a pushing device II3 and a plurality of clamping devices 4; one side of the housing 1 is provided with a pushing For the device I2, the other side of the housing 1 is provided with a pushing device II3, and the inside of the housing 1 is provided with a plurality of clamping devices 4 .

specific Embodiment approach 2

[0021] Specific implementation mode two: as Figure 1-8 As shown, this embodiment is a further description of Embodiment 1. The housing 1 includes a bottom plate 11, two elastic telescopic rods 12, a housing 13 and a limit rod 16; the side of the housing 13 is fixedly connected with Two elastic telescopic rods 12, the free ends of the elastic telescopic rods 12 are fixedly connected to the upper end of the base plate 11; the limiting rod 16 is fixedly connected to the outside of the shell 13; the outer shell 13 is provided with the top of the side of the limiting rod 16 A through hole I14 is provided, and a through hole II19 is provided on the side wall opposite to the wall provided with the limit rod 16; slides are arranged symmetrically on the two side walls adjacent to the wall provided with the limit rod 16 on the housing 13. Groove I17, chute II18, chute III110 and chute IV111, the chute II18 and chute I17 are arranged on the inner wall of the casing 13 close to the top, ...

specific Embodiment approach 3

[0022] Specific implementation mode three: as Figure 1-8 As shown, this embodiment is a further description of specific embodiment 1. The length of the chute IV 111 inside the housing 13 is equal to the sum of the lengths of the chute I 17 and the chute II 18, and the depth of the chute III 110 is less than that of the chute Ⅰ17, chute Ⅱ18, chute Ⅳ111. The function of the chute III 110 is to prevent the clamping block 41 from shifting left and right when moving from bottom to top, so as to avoid breaking away from the length range of the chute II 18 .

Abstract

The invention discloses a random question setting device for high mathematics teaching and a use method thereof, and belongs to the field of teaching equipment. The device comprises a shell, a pushing device I, a pushing device II and a plurality of clamping devices. The pushing device I is arranged on one side of the shell, the pushing device II is arranged on the other side of the shell, and the plurality of clamping devices are arranged in the shell. The device can be used repeatedly, resources are saved, questions which are set once in a class cannot appear repeatedly, the situation that class time is wasted due to the fact that the same questions appear repeatedly is avoided, a question setting board can be recovered to the initial state conveniently, the time of a teacher is saved, and the teacher has more time to have a rest in the class.

Description

technical field [0001] The invention relates to a random question-setting device for advanced mathematics teaching and a method for using the same, belonging to the field of teaching equipment. Background technique [0002] In the teaching of advanced mathematics, especially in the teaching of calculus, etc., it is necessary to practice repeatedly for students, and appropriately ask some difficult questions to check the knowledge mastery of students. At present, the commonly used method is that teachers use A4 paper in advance It is a waste of paper to print the questions and send them to the students. However, if the teacher writes on the blackboard, it will waste time because the questions are long. Therefore, this question making device is designed. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the background technology, to provide a kind of random questioning device for advanced mathematics ...
