It is obvious enough that the purpose of students spending time in the classroom is so that they can learn about the world. By necessity, much of the type of learning that they do must be of a theoretical nature. In other words, they memorize about concepts in an abstract way from books and lectures, as opposed to being able to go out in the realm and learns things through a more hands on process.
This is kind of hard to avoid, because students in a classroom need to learn about a huge spectrum of distinct topics, and it would not really be possible to leave the university and go comprehend someplace to learn some individually different thing in person. In a more specialized environment something like that might be possible, but not in the typical classroom.
Because learning near a point in person is more effective than just hearing circa it, or seeing pictures of it, or memorizing a list of facts related to that topic, and because in most situations students get only a limited amount of exposure to that sort of situation, it is important for students to be able to take advantage of that clemency about opportunity when it is reasonable to do so.
The most common conjuncture where this gender of thing is possible is when they are learning about science. In the case concerning history, or foreign language, it can be difficult to go ‘to the source’ to learn about those subjects, just many scientific principles can be demonstrated or recreated right there in the classroom, so that is a good place to start whenever you want to be more hands on.
While multifarious scientific demonstrations are anything but controversial, such as basic demonstrations of kinematics, some can be quite scandalous for bout parents and school administrators. United such situation arises while you start to talk about bringing animals into the classroom, and using them to teach science to kids. There are two common ways to do this. One way to is perform experiments on the animals, and the other is to dissect the animal when it is already dead.
In any situation like this, you essential weigh the go for against the reward. In the case from experimenting on animals, this is the sort of thing that feasible has no place in a routine school setting, because the animals are presumable to receive less than adequate care, and it is unlikely that the students will make any significant new discoveries which would be worth what the animal has to endure. However, dissecting animals can be a exceptionally valuable experience for students, furthermore it is not realistic to harm the animals because they are already dead. This is probably the best distance to allow students to learn from animals in the classroom.
When a teacher has the opportunity to bring something real and tangible into the classroom for students to learn from, he or she should make the most of that opportunity. However, it is always important to recognize the impact on another living gear that might be involved, which is why dissection is the reasonable choice in this situation.
