Problem Solving Strategies and Hurdles

Let's become detectives of our own minds by investigating how we tackle challenges, from simple puzzles to complex life decisions.

Activity 01

• Collaborative Problem-Solving
• 15 min · Small Groups

The Unusual Uses Challenge

Give small groups a common object, like a newspaper or a brick, and challenge them to brainstorm as many non-traditional uses as possible in five minutes. This activity directly confronts functional fixedness by encouraging divergent thinking.

Analyse the different stages involved in the process of solving a problem.

Facilitation Tip

Celebrate the most creative or funny ideas to create a positive and non-judgmental atmosphere.

What to look for

Give students a scenario (e.g., 'You are locked out of your house'). Ask them to list the steps they would take, then identify which steps are heuristics versus algorithms.

Activity 02

• Collaborative Problem-Solving
• 10 min · Pairs

The Nine-Dot Puzzle

Present the classic puzzle of connecting nine dots arranged in a 3x3 square using only four straight lines without lifting the pen. This puzzle is a powerful demonstration of overcoming a mental set by literally 'thinking outside the box'.

Explain how mental set and functional fixedness can act as barriers to effective problem-solving.

Facilitation Tip

If pairs are stuck, hint that their assumptions about the boundaries of the square might be the problem.

What to look for

A short-answer question asking students to analyse a case study of a famous invention, explaining how the inventor overcame functional fixedness or a mental set.

Activity 03

• Collaborative Problem-Solving
• 25 min · Small Groups

Algorithm vs. Heuristic Race

Provide a complex but solvable problem, like finding the best route to deliver parcels to ten different locations in a neighbourhood. One group must use an algorithm (calculating every possible route), while another uses a heuristic (e.g., 'go to the nearest location next'). They then compare their solution's speed and optimality.

Evaluate the effectiveness of algorithms versus heuristics in finding solutions.

Facilitation Tip

Debrief by discussing which method would be better for different real-world scenarios, like planning a Mars rover's path versus deciding your daily commute.

What to look for

Students maintain a 'problem journal' for a week, noting one problem they faced each day and reflecting on the strategies they used and the hurdles they encountered.

A few notes on teaching this unit

Start with a relatable puzzle to hook students and demonstrate a mental hurdle in real-time. Then, introduce the formal stages of problem-solving as a 'toolkit' for their minds. Use plenty of real-world examples, from planning a party to solving a crime, to connect abstract concepts like 'heuristic' to their daily experiences.

Students will be able to identify the systematic steps to solving a problem and recognise the mental traps that often prevent them from finding the best solution.

Watch Out for These Misconceptions

• Heuristics are just lazy or wrong ways of thinking.

  Heuristics are essential mental shortcuts that help us make quick, efficient decisions every day. While they can lead to errors, they are incredibly useful for complex problems where a perfect solution is not necessary or possible.

• Problem-solving is a linear process; you just follow the steps in order.

  Effective problem-solving is often a cyclical process. People frequently have to go back to redefine the problem or generate new solutions if their initial plan does not work.

• If you are smart, you should be able to solve any problem quickly.

  Getting 'stuck' is a normal and universal part of problem-solving. Cognitive hurdles like mental set affect everyone, regardless of intelligence. Recognising these hurdles is actually a sign of good problem-solving skills.
