Description

Technical Field

[0001] The utility model relates to the field of demonstration and game teaching aids, in particular to a demonstration and game teaching aid for elementary school mathematics possibility (probability). Background Art

[0002] Possibility (probability) is one of the branches of mathematics that studies the laws of quantitative random phenomena. The phenomenon that a certain result will inevitably occur under certain conditions is called a deterministic phenomenon. Possibility (probability) is an abstract concept that is difficult for primary school students to understand. In current teaching, teachers generally use demonstration teaching aids to assist teaching, concretize and visualize abstract possibility (probability) problems, and guide students to collect, organize, describe, and analyze data from the observed possibility phenomena, understand the concept of possibility (probability), and qualitatively describe the probability of simple random phenomena.

[0003] In the existing possibility (probability) mathematics teaching, teachers mostly use coloring turntable demonstration teaching aids. The coloring turntable is drawn once, and the turntable structure, surface pattern, color, and numbers are fixed and cannot be replaced. The scope of teaching is limited and it is not suitable for gamification learning (gamification learning means "in an educational context, teachers organize children's learning by designing learning activities with game elements based on core concepts and key abilities. It is a way of learning for children; it is active learning triggered and maintained by positive emotions"), which is not conducive to exploratory learning and the development of students' scientific literacy. Summary of the invention

[0004] Based on the needs of the teaching reform of the "Compulsory Education Mathematics Curriculum Standards (2022 Edition)" and the "Compulsory Education Science Curriculum Standards (2022 Edition)" and the above analysis of the actual situation, the utility model provides a demonstration and game teaching aid for elementary school mathematics possibility (probability). Teachers can use the utility model for demonstration teaching, and students can use the utility model for gamification learning, explore in games with self-defined rules, and develop mathematical literacy and scientific literacy, so as to solve the lack of functions of demonstration teaching aids in existing teaching.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a primary school mathematics possibility (probability) demonstration and game teaching aid, the teaching aid is composed of three parts: a "rotating magic disk (1)", a "pointer (2)" and a "magic block (3)". The "rotating magic disk (1)" is a circular thin plate, and a through hole "pointer installation hole (6)" is provided at the center of the circle, which is convenient for the rotation axis (7) of the "pointer (2)" to pass through and can be flexibly rotated. The radius length of the "rotating magic disk (1)" matches the size of the palm of the primary school student. The primary school student can hold the "rotation axis (7)" of the "pointer (2)" with one hand, and use the other hand to arbitrarily install and uninstall the "magic block (3)" on the 12 "positioning hemispheres (4)" that evenly divide the circumference of the "rotating magic disk (1)". The "magic block (3)" is designed as a whole using bright, bright and warm three primary colors to reduce children's cognitive impairment and learning burden. The "magic block (3)" is provided with a through hole "positioning hole (9)" and a "positioning groove (10)" which respectively cooperate with the "positioning hemisphere (4)" and the "positioning pin (5)" of the "rotating magic disk (1)". The size of the "magic block (3)" matches the size of the thumb of a primary school student at a high level, is suitable for grasping and operating, and is not easy to fall.

[0006] In summary, the utility model mainly has the following beneficial effects: the utility model sets a hemispherical positioning hemisphere (4) at the edge of the "rotating magic disk (1)", and can lock "magic blocks (3)" of different colors on the periphery of the "rotating magic disk (1)". Teachers can assemble "magic blocks (3)" of different colors, different numbers and different positions according to teaching needs, and students can assemble "magic blocks (3)" of different colors, different numbers and different positions according to the needs of game rules, so as to design a combination with rich cognitive conflicts, and the installation is simple, convenient and diverse. The appearance of the utility model uses rounded corners or arc shapes, bright and warm three primary colors design, safe and reliable, and convenient for teachers to demonstrate teaching and students to operate games.

[0013] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in combination with the drawings of the specification of the present invention. The following implementation examples are only used to explain the present invention and cannot be understood as limiting the present invention.

[0014] The following describes an implementation example of the utility model based on its overall structure.

[0015] A primary school mathematics possibility (probability) demonstration and game teaching aid, as shown in Figures 1 to 5, consists of three parts: a "rotating magic disk (1), a pointer (2), and a magic block (3)". The "rotating magic disk (1)" is a circular thin plate, and a through hole "pointer installation hole (6)" is provided at the center of the circle, so that the "rotation axis (7)" of the "pointer (2)" can pass through and can be flexibly rotated. The radius length of the "rotating magic disk (1)" matches the size of the palm of the primary school student. The primary school student can hold the "rotation axis (7)" of the "pointer (2)" with one hand, and use the other hand to arbitrarily install and uninstall the "magic block (3)" of three primary colors on 12 equally divided positions of the "rotating magic disk (1)". The "magic block (3)" cooperates with the "positioning pin (5) and the positioning hemisphere (4)" of the "rotating magic disk (1)" through the "positioning groove (9) and the positioning hole (10)" and is not easy to fall off.

[0016] During the demonstration teaching, the teacher can design and install different numbers, colors, and positions of "magic blocks (3)" on the "rotating magic disk (1)" to fill it with 12 blocks. The teacher holds the "rotating axis (7)" of the "pointer (2)" with one hand, and before turning the "rotating magic disk (1)" with the other hand, ask the students to guess what color the "magic block (3)" pointed to by the "pointer (8)" is most likely to be when the "rotating magic disk (1)" stops turning. Ask the students to put forward their own guesses and hypotheses, give reasons, and record them. Then, let the students work in groups to operate the teaching aids, independently cooperate in exploration, and verify their own guesses and hypotheses. Under the guidance of the teacher, students experience scientific inquiry links such as raising questions, making assumptions, making plans, collecting evidence, processing information, drawing conclusions, expressing and communicating, and reflecting and evaluating, so as to achieve the goal of understanding the abstract concept of possibility (probability) and developing scientific thinking and inquiry practice ability.

[0017] During gamification learning, teachers or students can set the game rules, operate the utility model, install and uninstall the "magic blocks (3)", and obtain a certain combination of cognitive conflicts. Then, students work in groups to experience scientific inquiry links such as raising questions, making assumptions, making plans, collecting evidence, processing information, drawing conclusions, expressing and communicating, and reflecting and evaluating, and apply and transfer the concept of possibility (probability), so as to achieve the goal of strengthening scientific thinking and inquiry practice ability.
