  9. Computer Literacy BASICS Defining Problem Solving • Problem solving is a systematic approach of going from an initial situation to a desired situation that is subject to some resource constraints. • Logical guidelines must be followed to identify the situation and find the best technology to apply to the situation.

  10. Computer Literacy BASICS Problem-Solving Steps 1. Define the problem. 2. Investigate and analyze the problem. 3. Identify possible solutions. 4. Select and implement a solution. 5. Evaluate solutions.

  11. Computer Literacy BASICS Define the Problem • Make certain that there really is a problem and identify what it is. • Clarify the current situation and identify what it should be. • If necessary, make notes or sketches.

  12. Computer Literacy BASICS Investigate and Analyze the Problem • Collect all available data about the problem. • This provides the information you need to make an accurate decision. • Sometimes this step reveals that there is no actual problem or that the problem is being caused by something else.

  13. Computer Literacy BASICS Identify Possible Solutions • Once the problem is defined and analyzed, consider what can be done to solve it. • See what can be done differently or what can be added or removed to the situation to fix the problem. • Ask questions, what can be done to solve this problem? What needs to be done differently? What needs to be deleted or added? • At this stage, you may identify several possible solutions.

  14. Computer Literacy BASICS Select and Implement a Solution • If multiple solutions are available, compare and test each one to determine the best possible choice. • When you have determined the best solution, implement it to fix the problem.

  15. Computer Literacy BASICS Evaluate Solutions • After implementing the chosen solution, analyze it to be sure that it has solved the problem. • Ask questions to assess the solution: • Did the solution eliminate the problem? • Did it accomplish the required task? • If your answers are positive, you have a solution to the problem.
