Problem Solving Methods

Solving problems can be either one of the hardest or easiest things to do in this course. Since we are still in the middle of our motion unit I would like to have a discussion about how YOU solve problems. You know the method that I tell you to use (identify knowns & unknowns, ID equation, show work and solve), but I want to know what really goes through YOUR head as you solve a problem. Here is what you need to do for this comment assignment...

1. Choose any problem on any assignment from our motion unit (make sure you identify the problem in your post)

2. Write in complete sentences exactly what you do as you solve the problem from beginning to end

3. Look back at your process and comment on whether you think this is the best process for you to use - is it effective?

**NOTE: It is NOT acceptable to simply state: "identify knowns & unknowns, identify equation, show work and solve." I want to know what goes through your head from the time you read the problem to the time you write down the answer.

4. Feel free to respectfully comment on each other's processes with tips or critiques.

Conversions, conversions, conversions...

I think it's safe to say that we are all fully aware that the number of technology tools available to us are increasing faster than we can keep track of. The amount of information available to us in a matter of seconds allows us to get answers to virtually any question that we have, regardless of the subject area. Many have made the argument against needing to memorize stuff in school or learn certain topics. Some make this argument when it comes to converting units and may say, "Why do I need to know how many feet are in a meter? I can just look it up online!" The statement itself is very true - there are many websites and probably apps out there that will allow you to do unit conversions without any need for pen and paper. That being said, what do you think? Why did we spend so much time learning about conversions in class? Is it worth knowing how the math works? When would you need to possibly do unit conversions?  Why do you think I thought it was so important for you to understand the unit conversion process?

Scientific Process Applied

In the Monty Python video clip shown below there are some very interesting interpretations of the scientific method. Watch the clip (quite entertaining!) and then think (and comment) about...
1. How is the scientific method demonstrated here?
2. How did the scientific method in the end allow for a bogus conclusion?
3. How is the scientific method used incorrectly?
4. Are there any aspects of the scientific method that are used correctly? Explain.
