Solving crimes using Concept Mapping

Have you ever wondered why in pretty much every crime drama the “hero” stares at a wall, with names, locations and pictures pinned to it. He’s trying to solve a crime but there’s no logic, nothing makes sense, he has more questions than answers. The phone rings, it’s his daughter asking when he will be home, the dog is barking in the background, then suddenly he puts down the phone and says “that’s it, why didn’t I see that connection before” “why did the dog not bark that night?” The connection is made and the crime solved.

What was on the wall was effectively a concept map, a visual tool used to organise and represent knowledge or ideas in a hierarchical manner, showing the relationships between them to help develop a better understanding, clarify relationship and in some instances solve problems.

Concept mapping
Although a concept map and a mind map are both visualisation tools, they are not the same. A concept map differs in that as the name suggests its focus is on the relationship between concepts rather than on a single theme placed at the centre of a blank page as is the case with a mind map. Another way of thinking about them is that concept maps are more suited to planning and organising, they have a structured hierarchy and highlight relationships. On the other hand, mind maps are “free spirits”, used more spontaneously, encouraging creativity.

A concept map typically consists of nodes, representing concepts or ideas, connected by labelled lines or arrows to indicate the relationships between them.

Why concept maps work
Concept maps are effective because they mirror the way our brains naturally categorise and store information. When we create one it activates various regions of the brain involved in memory, comprehension, and critical thinking. This process helps to reinforce learning and deepen understanding by facilitating the formation of neural connections. Additionally, the visual nature of concept maps appeals to the brain’s preference for processing information in a spatial and interconnected manner, making it easier to grasp complex relationships and retain information over time.

Concept mapping as a technique was developed by Dr. Joseph D. Novak at Cornell University in the 1960s and is based on the theories of Dr. David Ausubel, who emphasised the importance of prior knowledge in learning new information. It stems from the ‘constructivism‘ approach to learning which suggests that individuals construct their own understanding and knowledge of the world, based on their own unique experiences.

“The most important single factor influencing learning is what the learner already knows. Ascertain this and teach accordingly.” David Ausubel. (1968).

Research also supports their use with studies showing that they improve learning outcomes, promote critical thinking, and increase retention of information. For example, a meta study published in 2024 concluded that “concept maps are highly effective in enhancing the academic achievement of students and must be used in the education process”.

How to design a concept map
Designing a concept map involves visually organising information to illustrate the relationships between concepts. Here’s a brief introduction to the process:

  1. Identify Key Concepts: Start by identifying the main concepts relevant to your topic. Think of them as the building blocks of your map.
  2. Determine Sub-Concepts: Branch out to list related sub-concepts, organising them from general to specific. Then start thinking about the relationship between the concepts, is there for example a cause-and-effect.
  3. Connect the Dots: Draw lines to connect related concepts, and label the lines to explain the relationships and organise in a hierarchy if not already done so.
  4. Refine and Expand: As you study, add more concepts and links, perhaps using colour to clarify different groupings, continually refining the map as your understanding develops.

Case study – Omelettes and Cognitivism

If you have actually got as far as reading this first paragraph, there must have been something in the title that caught your attention. Perhaps you were simply curious as to how these three words are connected, or maybe one of the words relates to something you are interested in?

Whatever the reason, you have begun to process information and so engage in cognition, put more simply, you have started to think.

Making an omelette

But first a question, take a moment and think about how you make an omelette? ……….Then in your own words, explain how you would do this? ………. As you might imagine this is not about the omelette but the process you went through in order to answer the question.

The process – There was clearly an element of memory and recall as you thought back to the time when you last made an omelette, you would also have needed to direct your attention to the event itself and use strong visualisation skills, to see yourself actually whisking the egg, adding the salt and pepper etc. However so sophisticated is the human mind you can actually create images of making an omelette based on your knowledge of scrambling an egg! The point being, you have the ability to visualise activities of which you have no or little experience. The mental processes outlined above go some way to explaining Cognitivism. Cognitivism in learning is the study of how information is received, directed, organised, stored and perceived in order to facilitate better learning. Cognitivist believe that mental processes should be studied in order to develop better theories as to how people learn.

Case study is higher level

As you progress up the exam ladder the style of examination question changes. It starts with relatively simple activities that require you to recall something already taught e.g. what is the capital of France? It then moves to questions that test understanding, e.g. explain why Paris is the capital of France? At higher levels you will ultimately come across, Application, Analyse and Evaluation, and it is these higher level skills that a case studies often requires you to master.

I have written about case studies before, firstly, Putting the context into case study and secondly Passing case studies by thinking in words. Here I want to explore how by understanding how people think  (Cognitivism) you can develop strategies to help you answer what seem to be impossible questions.

Application of knowledge

Imagine you have been given a case study that has a large amount of information about the company, the people and the financial position. You have been asked to offer advise as to how the company should improve its internal controls within the HR department. Even though you may not think you know the answer, the process outlined above will give a framework to follow.

  • Firstly, focus your attention on the key words – internal controls and HR deportment
  • Secondly, recall any information you have about internal controls and HR departments
  • Thirdly, deploy strong visualisation skills, seeing yourself in that company, bringing in as much detail as possible to give context, and then use common sense
  • Finally write out your answer – Say what you see, talk through how you would do it, mention some of the problems you might experience and outline the possible solutions

These are cognitive strategies developed from learning more as to how people think, why not give them a go?
