Especially between students, could be met the practice of underlining or marking a chunk of text with special marker(s), highlighting the respective text as important, at least for a second review. The chunk of text could be a concept, a definition or a whole paragraph, and that’s actually the input for a K-map. In theory you could put the whole chunks of texts together on post-it or electronic documents, group them together in some way, and there you have a rudimentary K-map. Thus could be intuited that a K-map is a graphic organizer of chunks of texts identified as information or knowledge. Putting together row text allows structuring the content based on identified associations, it could be sequential structure, logical implication, importance, topic, etc.
From a visual perspective, processing a whole chunk of text could be time consuming, especially when we look for specific information, typically key words, primary concepts, definitions, etc. Marking such text in special ways brings some additional value, though the linear character of text makes it still difficult to process. What if we break the text at conceptual level? Wouldn’t such output be easier to process? Now it depends also on each person’s capabilities, though working with concepts seems closer to the mental structure of our mind, in the way meaning is represented and created.
Until now we considered a K-map as being an aggregation of chunks of text of various granularities, implied or explicit associations, and the later could be labeled using other more or less standardized concepts. We talked also about formatting, meaningful display, resources, symbols and other types of markings. These are in fact the content elements of a K-map, but in definitive what is a K-map?!
Extrapolating the above considerations, a Knowledge Map or K-map could be considered as a visual graphical tool used to aggregate and represent information or knowledge. The definition seems to need further refinement because the graphical character implies a visual component, representation could involve aggregation and thus the later term could be abandoned, while following the DIKW pyramid, knowledge involve information. Graphical is the form of representation, while the role of visual is to represent explicitly the channel of communication, in fact stressing its visual, respectively graphical character, a K-map could be considered as synonym to visual aid or graphical organizer, terms more frequent used, especially in teaching. No matter of the degree of knowledge encompassed, a representation of the knowledge is not the knowledge itself, it resumes thus to information that triggers knowledge and the associations existing between information. Thus, a K-map could be defined as a visual graphical tool used to represent information and the associations existing between them, either implicit or explicit. The term information encompasses here any type of symbols or chunk of texts. When information is present in its most granular form, at concept level, the K-map is a visual graphical tool used to represent concepts and the associations existing between them.
The definition of a K-map represent the “what” from the W5H1 syntagm, how about the why, who, when, how, by whom and by what means? Why a K-map, isn’t the text or what we know enough? Do we really have to break the knowledge into such maps? Maybe we don’t, it depends on each persons capacities, some of us have a really good memory, retain everything they read and recalled it any time. For others, such capabilities come with some effort, spending some time in memorizing the information we consider as useful for the future, and also this step depends on each person’s capabilities and skills. As mentioned in introduction, the read material could be “formatted”, broken into pieces, annotated, summarized, restructured in order to increase the efficiency of memorization and recall.
The creation of a K-map requires additional time, time we don’t always have. Does it really make sense to create such a map all the times? It’s probably recommended to create it when we acquire new knowledge, especially when we want to identify the concepts on which the respective chunk of knowledge is built upon. Once the backbone concepts mastered, the necessity of a map decreases to some degree, in the end its necessity depending on individual needs. A K-map could be useful also when externalizing the knowledge, especially the tacit knowledge, in organizations being quite a valuable tool in documenting the various types of information organization work with, process maps, flow maps, value stream maps, being several examples of such K-maps.
How to create a K-map? In definitive maybe we create such maps without knowing it, it’s built in our “ADN” as we often arrive to express complex thoughts by externalize them in diagrammatic form. There are more than 50 types of K-maps available in the literature: Concept Maps, Semantic Nets, Conceptual Graphs, Mind Maps, and so on. They have many similarities, often the similarities residing in the philosophies used to create them. Adhering to one or more of such maps is a question of need, preferences, habitude and requirement. Sometimes also deviations from the philosophy behind a map could prove to be useful as long satisfies a purpose, same as a map arrives to be misused, for example by placing too much content, be it irrelevant or relevant, or of using too much formatting, not respecting guidelines, etc. There are several requirements a K-map should satisfy – it should be simple to use and navigate, with an approachable level of complexity and thus understandability, adaptive and dynamic.
“By what means” could refer here to the tools used to create K-maps and the channels used to distribute them. Again it’s a question of need, preferences, habitude and requirements. In the past years appear many tools used for the creation of K-maps, having multiple features, but still lacking in representational content the human mind is used to. The paper and a crayon could prove efficient as well, while those with an exceptional memory could create such maps directly in the inner mental world. Everything is possible, everything it’s a question of practice and self-improvement of techniques.
