It is difficult to define good thinking, it is hard to understand how the way you think can be wrong or flawed, that is until you truly analyse the way you think and learn.
When you read information from a book, do you automatically assume it is correct? When your teacher explains something to you take their explanation as absolute? Do you believe the information you hear on the news or read in the newspaper is fair and unbiased? These are all areas where you can improve your thinking, you can look for proof and evidence that what you have read or been told is true. This process is called being analytical, and is one of the things examiners and universities are looking for in their top students.
How can you develop your thinking skills? There are many things you can do to develop your thinking skills, complete crossword or sudoku puzzles, talk about your learning with your friends and family, read a wide range of material or simply by being creative, painting, writing or crafting. Edward De Bono a leading authority on thinking says "Many highly intelligent people are poor thinkers. Many people of average intelligence are skilled thinkers. The power of a car is separate from the way the car is driven."
