Thinking Skills and Problem Solving Model

At the top is the analysis process, the management of the investigation into the structure of the situation. We gather in information, and look for significant stable elements. These might be People, Things, Ideas or Events (P.T.I.E.). We classify/categorise them by looking at their similarities and differences. We look at the way these things behave and interact, their capacity to affect each other, the range and circumstantial limitations of their capabilities, patterns of activity, trends, sequences, relationships of cause and effect, etc. Ever mindful that we live in a sea of false assumptions, we repeatedly test our latest understanding, taking measurements and setting up experiments to test out

ideas. We know from experience that a single viewpoint can produce a flawed and incomplete perception, so we try to look at the situation from many different points of view, deliberately looking for what we may have missed, particularly when we have assumed something was obvious. The analysed information is generalised and abstracted, and built into a Graphical Thinking Model (centre right) that contains all our knowledge about the nature and behaviour of all the participating elements, and the subtle nuances and limitations of the relationships between them. Winding the handle, and exploring the emergent properties of the model, will suggest ways in which the situation can be adjusted and transformed. Upper centre left - we have the problem and goal framing process. What do we know about the problems we are trying to overcome and the goals we are trying to achieve? Whose viewpoints are we looking at it from? What is the boundary, how far are we prepared to go to get a solution? What filters are we imposing? What aspects of the situation are we interested in (economic, mental, spiritual, cultural, ecological, environmental, political, marketing, PR, etc.) and what are we excluding? What methods and practices will we accept and reject en route? The framing of the problem can be dynamic and iterative, as it may be influenced by the information that comes to light during analysis, or in the exploration of the consequences of possible actions. Likewise, changes in the problem definition may mean we need to adjust the scope and focus of the analysis. Now we are into the problem-solving phase, winding the handle to generate a range of options that will hopefully have the effect of getting us to our goals without creating any more problems. The options are evaluated: what are their consequences, are they worth the effort, do they change our understanding of the problem or the framing of our goals? The answers may be intuitively obvious. If not, we may need to employ some mathematical decision support tools to help us decide which of the models predictions give the best solution. Then we try the best solution(s) in the real world. Hopefully it works just as the model predicted. Rejoice. If it doesnt, be happy, because we have potentially got some useful information to add to our model of reality. The final problem is to decide when to stop. If we have worked hard but have not found a satisfactory solution, then at some point it may be sensible to stop trying. Even if we have found a satisfactory solution, we might find an even better one tomorrow or the next day, if we keep trying. Deciding when to stop is not an easy judgement because it is impossible to know how much effort it would take and how much better the improved solution would be, if we were to find one. Most of this activity takes place in our heads, with occasional experiments out there in reality, to see if our predictions are accurate, and to test if our mental model is still an accurate representation of reality. The balance between the mental and practical depends on the nature of the problem. If you are a rocket scientist trying to get a space probe to Mars, you do most of it in your head (with the aid of computer simulations). If you are a sculptor trying to beat a piece of metal into an interesting shape you do most of it out there in reality. There is a story that the Americans designed their space rocket motors with a lot of expensive computer simulations and the Russians built theirs using a lot of

cheap trial and error, (build it, fly it, see what happens, learn). The Russian rocket motors were much better, more efficient and cheaper to build. After the Soviet system collapsed the Americans bought a job lot of surplus Russian rocket motors. I dont know if its true. How Does This Dynamic Approach Contrast With The Usual Critical Thinking Models taught in schools if you are lucky.

Figure 4.16 A typical critical thinking model with isolated components. This is a mind map style diagram that represents a fairly typical Critical Thinking style approach to thinking and problem solving. As you can see, it chops thinking into a number of separate isolated skills. This particular map represents the ideas in a document advising teachers to plan lessons that focus on the development of each specific thinking skill, in isolation, such as analysing or information gathering.

Figure 4.17 Connecting the isolated parts.

This amended version of the diagram seeks to demolish the idea of the separateness of these skills, by identifying just some of the interconnectivity that is involved in realworld problem solving. For example, in order to be able to analyse something into its attributes and components, we must surely get involved in classifying, comparing, ordering, and integration, before we can assemble the elements into a model that shows the relationships and patterns. If I put all the obvious interconnections onto the diagram it would become a blur. Problems with Language Some of our essential logical words (is, are, causes, all, some, etc.) are fundamentally vague and commonly misunderstood. For example: Is (and Are) There are problems over the exact meaning of is and are. What do we mean when we say, this is a table. A table (the physical object) is not exactly equal to its name table. A thing is not its name, it is a collection of properties and relationships with the world. If we say, the table is green, we are only describing one of its properties, one small aspect of its existence. If we say, it is a coffee table, we are either describing one of its properties, or its membership of a particular class of tables. So is does not usually mean =, but the brain often assumes that is does mean =. Is often becomes All If you say, X is Y people very often assume that you meant that ALL Xs are Y. Direction of Causation We often jump to wrong assumptions about the direction of causation. This happens when our neural networks interpret X causes Y as X and Y are associated. Association is a link that works in both directions, but causation only works in one direction. So we jump to the assumption that X causes Y, also means, Y causes X. This is much more likely to happen at the beginning of the learning curve, or in domains where we have no personal experience of the relationship between X and Y. If you know that sour apples cause stomach ache, you are not likely to jump to the assumption that stomach ache causes sour apples, but if I said that the movement of masons causes fluctuations in the strong nuclear force, you might well assume that variations in the strong nuclear force can cause massons to move as well. (N.B. I invented massons, as far as I know they do not exist.) Extracts from Understanding Thinking
