Embodiment 1

[0030] Embodiment 1, adopt self-adhesive chromosome model ( figure 1 ) and the mitotic puzzle base plate ( Figure 5 ), can demonstrate the change of chromosome behavior during mitosis; taking 2 pairs of chromosomes as an example, the specific demonstration principle is as follows:

[0031] (1) In mitotic interphase: From the self-adhesive chromosome model ( figure 1 ), remove the circular nuclei model (containing chromatin filaments), and paste it on the base plate of the mitosis puzzle ( Figure 5 ) in the interphase box diagram, visualized to simulate that during interphase of mitosis, chromosomes are in filamentous chromatin morphology. After each chromosome is replicated, it contains two sister chromatids, but because it is difficult to observe under the optical microscope during the interphase, the model of this phase is not reflected.

[0032] (2) In the prophase of mitosis: From the self-adhesive chromosome model ( figure 1 ) from the long and short pairs of "X"-sh...

Embodiment 2

[0037] Embodiment 2, adopt self-adhesive chromosome model ( image 3 ) and cell division puzzle base plate ( Figure 5 ), can demonstrate the change of chromosome behavior during mitosis;

Embodiment 3

[0038] Embodiment 3, adopt self-adhesive chromosome model ( figure 2 ) and cell division puzzle base plate ( Figure 6 , Figure 7), which can demonstrate the change of chromosome behavior during meiosis;

Abstract

The invention discloses a cell division chromosome model jigsaw teaching aid and a simulation method thereof. The teaching aid comprises adhesive sticker chromosome models and a cell division jigsaw bottom plate. The invention aims to solve the technical problem of difficulties in manual manufacture, mass production and use of an existing cell division chromosome model teaching aid. According to the cell division chromosome model jigsaw teaching aid of the invention, the adhesive sticker chromosome models are adopted to simulate the behavior change rules of chromosomes in a cell division process and corresponding gene behavior changes, and therefore, the teaching of cell division, genetic rules and variation can be visualized, the teaching of a teacher and the collaborative learning of themanual operation of students are combined with each other, simulated phenomena are more intuitive and interesting, the students can be facilitated to understand and master relevant knowledge.

Description

technical field [0001] The invention belongs to the technical field of stationery and educational equipment, and in particular relates to teaching aids for jigsaw puzzles of cell division chromosome models. Background technique [0002] The application of teaching aids in biology teaching can increase students' hands-on and brain-using opportunities, provide sufficient perceptual knowledge as the basis for abstract thinking, make boring knowledge interesting, abstract concepts concrete, and esoteric principles visualized, effectively It effectively mobilized the students' interest in learning, reduced the difficulty of thinking, and improved the efficiency of learning. For this reason, many model teaching aids for simulating cell division have been proposed in the prior art, which generally adopt simple materials and are made by hand. For example, the utility model patent CN203931266U, "Mitosis Chromosome Change Demonstration Teaching Aids" uses materials such as square fra...
