Speaking of which, I recently heard from a friend who was a teacher, saying that they had changed a new school set of teaching aids, and that the students had doubled their motivation in the course, putting him under a lot of stress. Think about it, the upgrading of teaching aids, which looks like equipment upgrades, actually has a much deeper impact on the whole of hands-on teaching than we thought.
Back in the day, the worst thing you'd ever fear was "The Paper Talker." In anatomy, the old plastic model's colour is distorted, the joints are still unwieldy, and the students can only remember their backs against the drawings. Now upgraded teaching aids, such as high-regnant silicone models, are not only handy close to real people, but also simulate different pathologies. You know what you're talking about. To be honest, the upgrading of teaching aids has turned "imagina" into "experiment," and hands-on teaching from "hearing the teacher" to "try it."
The most obvious thing is the drop in the trial error cost. In the past, the nursing profession practiced needles using ordinary rubber blocks, and it didn't feel like it, and students didn't know how strong it was. The new teaching aids now have pressure sensors, and when they are reinforced, the red light will be activated, and they will have a reblood effect. Students can practice over and over again, without fear of wasteful materials or damage to equipment. This instant feedback makes learning work.——The skills that had previously taken a week to master are now probably well understood in two days.
说实话，对老师是好事，但也不轻松。以前讲人体骨骼结构，老师得在黑板上画半天，学生还听得晕乎乎的。现在拿出 3D 拼装模型，学生自己拆装几遍，比听十节课都管用。老师可以把更多精力放在答疑和纠错上，而不是重复演示。不过，新教具往往配套了数字化系统，老师得先学会怎么用，有些年纪大的老师还真得花点时间适应。好在大部分厂家会提供培训，算是一道过渡期。
The upgrading of teaching aids sounds like a big deal, but the worst thing about schools is the budget. A model of high-simultaneous care is very close to 10,000, and it hurts to buy a few of them in a general school. In other words, if a student is able to work directly after graduation because of his or her teaching skills, the cost of re-training in the enterprise is saved, which is actually a cost. Some schools have adopted a "several upgrade" strategy, changing teaching aids for the core curriculum, and others slowly. It's also a way of "old for new" or a rental model with a teacher.
At the end of the day, teaching tools are just tools. I've seen schools pay a lot of money to buy smart simulators, and teachers are in trouble, locked in cabinets, and only in public classes. It's no different if the teacher doesn't work, the students don't practice. The core of hands-on teaching is "people."——How the teacher leads, how the students do it. The upgrade is just a fire to the process. It depends on how it works.
反正，现在走在实训楼里，看着那些新模型、新设备，感觉教学确实不一样了。至少，学生再也不用对着课本上的平面图，硬生生背出人体 206 块骨头的位置了。

I've been in the nursing room before, and that needle simulator really works.
To tell you the truth, you don't need a teacher. There's too many cases of ash.
Silicon-gel models do feel much better than plastic.
It's a very high cost, but I remember the school had a lease with the factory, which eased the budget pressure.
I feel like my teacher's under stress. We'll have to start over.
Those 3D models are better than drawings, but they don't look like every school has money to change.
I'm still gonna have to do it.
The old equipment I used earlier, the buttons were still in use.
There's not a lot of medical training.
