Making it harder to cheat

Here is the problem: teachers want to engage their students with interesting demonstrations and activities to motivate them to think about  a scientific concept. Students, on the other hand, just need a good mark on the tests and assignments so they can become a doctor, or a lawyer, a cobbler or a candlestick maker, etc.

As the technology available to students to help them answer their assignment questions gets better, teachers need to think about how to structure questions to make students think, rather than just google the answer.

Here is an example of a pretty standard sort of test/assignment question; What properties of aluminium make it suitable for use in cooking pots.  Give a disadvantage of using aluminium for pots.

If you copy and paste that into google, there are 2,090,000 results, and the top of the page will read, "Aluminum is lightweight, cheap and very good at distributing heat. It doesn't retain heat particularly well though, so the temperature will fluctuate as food is added to a hot pan. It's also the softest metal on our list, so it will scratch and dent pretty easily."

Assignment done! No thought required!

So we need to re-structure the question. How about this...

On the planet P42da, the element potsnpanium is used to make large pots in which the P42daians heat soup to above the boiling point of liquid water at 1 atmosphere. What properties of potsnpanium make it suitable for this purpose. Give an example of a safety precaution the P42daians should take when handling potsnpanium pots. Describe a way to reduce this hazard.

Copied and pasted into google this yields 0 results and a heap of useful suggestions:

"

  • Make sure that all words are spelled correctly.
  • Try different keywords.
  • Try more general keywords.
  • Try fewer keywords.

"

Might force some students to have a think about it.

Problem Solving in Chemistry

Some years ago, AUS-e-TUTE added a "how to solve problems in chemistry" page.
We call this approach to problem solving the StoPGoPS method:
  1. Stop: State the question.
  2. Pause: Prepare a plan of how you will solve the problem'
  3. Go! Follow the steps in your plan.
  4. Pause: Ponder the plausibility of your answer. (Have you answered the question you were asked? Does the answer look "about right"?
  5. Stop: State your solution (if your answer seems plausible) or Start again (if your answer doesn't look right)
Well, we have now added a Template that students can use to help guide them through the Problem Solving Process. You can download this "Template for Problem Solving" pdf at ausetute.com.au for free.

60 Second Chemistry Quiz Challenge

Over the past few years AUS-e-TUTE has received a lot of feedback.
One of the things that we hear a lot from teachers who are part of an AUS-e-TUTE Class or School Group Membership is that the students love to do the drills. They love to see how many questions they can get done quickly.
Well ..... we thought we could turn some basic chemistry concepts into timed challenges.
And ..... we've just uploaded the very first of these. We've called it the 60 Second Chemistry Quiz Challenge because you have just 60 seconds to answer as many questions correctly as you can.
This 60 Second Chemistry Quiz Challenge is called "It's Elementary", so I'm sure you can already guess what the questions are about :)

You can have a go yourself at:
