Session Two: Problem Solving
1. Exploring Websites

Procedure

1. Ask participants to think individually about their own school math experiences. Ask them to focus on how information was presented to them, what they were expected to do with that information, and what happened after that. Give them 3-5 minutes to jot down some ideas.

2. After five minutes, ask them share their recollections. Try to find common experiences and relate them to the process of problem solving.

The scenario you are most likely to hear will be something like, “The teacher lectured and put problems on the board, we had to solve the problems, and whoever got the right answer first told how s/he got it.”

3. Ask if they ever heard “You got the right answer but you did it the wrong way.” If you get affirmative responses, ask them what message that conveyed to them.

You’re looking for something like “it told me that there was only one right way to get one right answer.”

4. Finally, ask, “What learning occurred in this situation for those who couldn’t do it the ‘right’ way?”

You will probably get several answers, e.g., they learned that they weren’t good at math; they didn’t learn anything; they had to learn on their own.

5. Make the following points:

  • Adults who come to our programs often were the ones who felt that they couldn’t do math because they couldn’t do it he “right” way.
  • In the math classes they knew—and in too many adult classes today—no opportunity existed for exploring “other” ways to a solution. In this kind of class, the focus is often on memorizing rules that would allow students to get answers the “right” way. If you couldn’t remember the rules, you couldn’t be “good” at math.
  • The challenge for adult educators is to change the structure of the math classroom so that the focus is less on getting the answer and more on the process of solving the problem.
  • Math as problem solving rather than answer getting is much closer to the way we “do” math in real life.
  • In everyday use, we frequently learn from our mistakes—so the process of problem solving must assume that mistakes will be made and it must articulate a way of dealing with them.
  • In practicing the process of problem solving, we develop an assortment of problem solving strategies that we choose from, trying and selecting strategies until we find one that works. The most successful problem solvers are those that have experience with a wide range of strategies.
  • Problem solving usually involves communication of some kind—in small groups, pairs, triads, or even “self-talk” where we “talk out” what we’re trying to do and how we’re trying to do it. This is one good way to learn about different strategies.
  • On-line math lessons and activities may support either the classroom that emphasizes getting the answer, or the classroom that emphasizes the process of solving the problem.

6. Ask participants to explore the websites listed on Handout 2a from the perspective of a teacher planning a lesson. Ask them to select three (3) websites to review and answer the questions that follow. Tell them that once their exploration is complete you will take a break, and then groups will share their impressions. Allow 60 minutes.

7. After 60 minutes, take a 10-minute break.

If possible get a discussion going as different individuals share what they found on the websites. How did their concept of a “good” lesson change as they considered shifting to the process of problem solving instead of just getting the answer? This is an opportunity to communicate about mathematics.

8. Tell everyone that for the next 40 minutes they will be sharing impressions of websites. If possible, project each website so that everyone can see it during the presentations. Begin with the Figure This website. Ask anyone who chose to review that site to share their impressions with the group. Invite others who also reviewed it to add their comments, to agree or disagree with the first speaker, or to give a different perspective.

9. Continue in this way through all of the websites. Because you can allow only 40 minutes for this debriefing and sharing activity, you will need to watch your time to ensure that you get to cover all the websites.

10. Wrap up this section by asking for any questions or final impressions.
