Problem Solving

The introduction reads as follows; Problem solving involves figuring out how to achieve a goal. Once you understand a problem, you can identify an approach to solving it. A successful approach will help you manage obstacles that come from the problem itself, such as a rigid deadline for an essay you’re struggling to write. But sometimes the way we think about a problem can itself be a barrier, preventing us from identifying available approaches.

The upper part of the infographic shows a flowchart with three steps;

1. Understand the problem
2. Choose an approach
3. Evaluate

1. The title reads, IDENTIFY INITIAL STATE; What do you know about the problem situation? What is the goal state? The illustration shows a person with two thought bubbles. The first is captioned Problem and reads, I need to register for classes, but I don’t know what to take. The second is captioned, Obstacles and reads, My major has requirements. Not every class is offered this semester. Some classes have prerequisites.

2. The title reads, TRIAL AND ERROR; Try every option.

   ALGORITHMS; Follow step-by-step procedure to guaranteed solution.

   HEURISTICS; Use general strategies that provide shortcuts.

   The illustration shows a person with a callout pointing to a checklist, captioned, Employ algorithm to narrow down options. The checklist items are as follows;

   Using catalog, find courses needed for major. Eliminate classes with prerequisites I don’t have. Check course offerings online. Register for available classes.

3. The title reads, PROBLEM SOLVED? If not, try again, with an arrow leading back to step 1. The illustration shows a stick figure holding a serving tray with a thought bubble that reads, No, I can’t take Biology. It’s only offered at 4;30 pm, when I have to be at work.

   The lower frame is titled Barriers to Problem Solving. The introduction reads as follows; Being stuck in a certain way of thinking about a problem can limit what we see as available approaches. For example, our student registering for classes may assume that classes must be in-person meetings with an instructor on campus. This assumption prevents the student from investigating more flexible online classes, hybrid classes, or classes that could be transferred from another college. Sticking with our usual solution strategies is called a mental set. To see if you can overcome your mental set, try solving this problem;

   A graphic shows a matrix of three rows of three dots. The task reads, Without lifting your pencil, can you connect all nine dots using only 4 straight lines and without crossing any dot more than once? Solution on page 252.

   On the right is a silhouette of a woman standing between two trees, holding a rope in one hand, and reaching to another rope with the other hand hanging from another tree to her left. The rope is beyond her reach. A small garden shovel is on the ground behind her. The caption reads, Functional fixedness is another barrier in which we can only imagine using familiar objects in their usual way. Say you need to tie two ropes together, but you can’t reach them both at the same time. Will functional fixedness keep you from solving this problem?, Solution on page 252.,
