Detailed ways

The technical solution of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention. Where reference is made to the figures, the same numbers in the figures represent the same or similar elements. The described embodiments are only some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

Example 1:

A simulation experiment teaching method, comprising the following steps:

1) Use the animation video method to set the graphics of multiple experimental elements. The animation video can be in the form of Flash, and the experimental elements refer to the conditions required for participating in the experiment. For example, experimental materials, tools, medicines, instruments and their changes, combined forms, etc. The graphic of the experimental element is a simulation of the experimental element, which is convenient for giving control instructions to the graphic in the animation video. The graphics of the experimental elements can intuitively and conveniently represent the experimental elements of the simulated objects, and then the changes of the experimental elements in response to the control instructions can be reflected through the animation video. Set up multiple control instructions for the experimental elements. The control instructions are the control names implemented on the experimental elements (its graphics), usually pointer control instructions, which include: selection or abandonment, movement, movement trajectory, movement speed, etc. For a specific experiment or a specific step of the experiment, the correct control instructions and the wrong control instructions of the current state are defined in the control instructions. The experimental elements are preset to correspond to the change effects and prompts of inputting correct control instructions. After correct operation of the experimental elements, the animation demonstrates the changes of the experimental elements. After the original experimental elements change, they will become new experimental elements, and so on until Improve experiment success. Preset the change effects and prompts of the experimental elements corresponding to the input error control instructions. After the incorrect operation of the experimental elements is performed, the changes caused by the incorrect operation of the experimental elements will be animatedly demonstrated, or the incorrect operation prompt will be directly given, or how to do here. The operation is prompted, and then the experimental elements before the wrong operation are restored, and so on.

2), monitor the input control command, and judge whether the input control command is correct. And play the change effect and prompt of the corresponding experimental elements. If the correct control command is input, the changed experimental elements are updated, and then the input control command is monitored until the end of the experiment; if the wrong control command is input, the experimental elements of the previous step are restored, the input control command is monitored again, and the cycle is repeated.

The control instruction is a pointer instruction, which specifically includes pointer state and movement track information. The experimental elements include simulated experimental names, experimental materials, tools, medicines, instruments, and their changes and combinations. The animation video also displays the experiment name, timing prompts, operation prompts and the number of errors. The plurality of experimental elements or changing effects may be selected by control instructions. The monitored input control command does not belong to the definition, ignore the control command and monitor again. If it is detected that the wrong control command is input, then a graphic prompt of the correct control command will be carried out.

Example 2:

A simulation experiment teaching method, as shown in Figure 1-Figure 7, shows the saturated salt water flotation method, which is simulated through the flash animation demonstrated by the computer. At the beginning of the experiment, the animation shows the experimental name, experimental equipment (cover glass, Graphics of experimental elements such as glass slides, bamboo sticks, saturated saline, petri dishes, penicillin vials, and filtered stools to be tested. By moving the mouse, control the pointer to select the experimental elements for experimental operation.

As shown in Figure 1, the correct operation at this time is to select the penicillin vial and move it to the plate. Selecting the experimental elements of other experimental equipment is regarded as a wrong operation. After moving the penicillin vial to the plate, an updated experimental element is the choice of the dosage form to add to the saline, which should be saturated saline. Then the updated experimental element is the selection of the amount of salt added, which should be less than 1/2 at this time. After adding the salt water, you should select a bamboo stick to dip the feces to be tested, select the bamboo stick with the mouse and move it to the feces for operation. After dipping the feces, move the bamboo stick to the vial, it will show that the feces are dissolved in the salt water, the salt water becomes turbid, and then continue to drip the salt water until it is almost full, and the animation prompts whether to continue dripping. You need to choose to continue dripping until the liquid level protrudes from the mouth of the bottle, which is about to overflow. Then move the slide to the bottle mouth and lay it flat, choose a resting time of 15-30 minutes, then remove the slide and invert it, place the cover glass, and observe it under a microscope. The experimental operation is completed.
