How do you teach chemistry which is very abstract to high school students? Can you share your modern approach and strategy in making chemistry fun yet fulfilling discipline?
As you said, chemistry is abstract. You need to find ways to make it less abstract. Labs are a great way to do this. Demonstrations are also an excellent way to help students see chemistry, without risking injury with volatile chemicals. Some of the concepts in chemistry can be reduced to basic models.
While it's not something I have personally taught, I have observed colleagues that engaged their students. I would suggest a lot of hands on learning. Many high school students will have trouble with the abstract concepts unless they can find a way to visualize or experience them. For example, our chemistry teacher had the students build models, play games, and complete lab experiments. For example, the students created fake snow (using chemicals during a controlled, supervised experiment) and then they had a snow ball fight outside in late May. It kept their attention on the lesson and they learned the material/concepts without realizing they were learning.
I've been teaching chemistry for 5 years now.The best way to teach chemistry is to use cool animations that will help students imagine the molecular world. I also make used of practical example and applications that will help the students appreciate the subject by relating to everyday life. Example, when you are introducing the periodic table let them realize that it is their best friend in chemistry. Teach them some mnemonics that they will NOT forget for the rest of their lives. Instead of just saying that period is the horizontal and group is the vertical part of the periodic table, you can also add that in the same way that you write your sentence from left to right and ends it with a period, so period is the horizontal (left to right) part of the periodic table. Spice up your lessons. Chemistry is fun :)
i, being a teenager, can say that it really helps if teachers really get us involved...
it really helps if they smile, first of all.... because chemistry is a very serious kind of thing itself.... :) :P
more hands on stuff with chemicals and models helps us learn better.
it also helps if they go a little slow so we have enough time to absorb the knowlege.... :)
