Things to ponder before and after Workshop 3:

1. Eliciting what students already know has implications for flexibility in the classroom: Instead of following a fixed lesson plan, a teacher adapts and makes modifications as a lesson progresses. How do you think this would work in your classroom?

2. Teachers who are familiar with common misconceptions about a topic are better equipped to elicit prior knowledge. Why?

3. One approach to summarizing students' alternative theories is:

  • Write the constrasting theories on the board.
  • Have a discussion with the class about what each one means.
  • Ask for a show of hands to determine how many students believe in each theory.
  • Tell students it is OK to change their minds.
  • Repeat this surveying of the class several times during a lesson.
What are the advantages of this approach?


Assignment:

Pretend you are going to teach a lesson to second-graders about cohesion and surface tension in water. You have planned the following experiment. You will give the children an eye dropper, a container of clean water, and a penny. Their job is to count how many drops of water they can put on the head of a penny. They do the experiment three different times and average the results.

Your task is to design a data sheet for these young children to use in recording their data. You may want to try the experiment yourself so you know what the range of values is likely to be. Good luck.
