Some thoughts on complexity and learning
Excuse my bad english
Interact SRK mecanism (Jens Rasmussen - 1986) - Skill Rules Knowledge
K : In this case, the user facing a new problem, is going to seek it in his knowledge, if of course he has, if not, and if he understand the problem, he can read web, books, help to friends, on a forum (if it exists or if it finds)
This phase is very heavy in mental charge, makes the individual vulnerable, he makes mistakes.
Context to its importance, for example today almost everyone uses a smartphone (with more or less difficulty…), because we talk about it, the neighbor, the father, the friends have it, and little by little the knowledge progresses.
Imagine Leonard of Vinci arriving in our time. Despite his remarkable intelligence, he will not immediately understand what a smartphone is, what it is used for, etc… when a 5 year old child knows how to use it.
This shows the influence of the cognitive environment (collective learning).
Does that mean that de Vinci is less intelligent than a current child of 5 years, of course not…
De Vinci in in a few days will catch up by learning.
In this phase the knowledge is built and gradually the user will build rules.
R: the users use rules he has learned, he knows how to use the process, he still makes mistakes, he is obliged to read the documentation often, the mental load decreases
S: little by little, by dint of practicing, the gestures become automatic, we do things without thinking and generally it is the right choice. The mental load is weak
Once we get to “S” the problem has stopped being complex
But,if the user does not practice during the moment, he forgets and is obliged to go back a step
The hierarchy of abstraction
She model the process environment, from the most abstract to the most concrete.
The users must be able to find what is essential to understand and use the process.
It goes from the ends and stakes, to the practice of tasks closest to the action : the documentation, the web, the trainings … must allow the user to understand the process and meet his aspirations
Clearly, the documentation (generic terms includind videos, Rawpedia, forums, etc.) of Rawtherapee (or others software) must be appropriate at each level: what are the purposes, → … ->. how do we concretely
Taxonomies
How is the individual (or group) facing the problem. It is in response to these questions that the actions to be carried out will be deduced !
Generally, but there is a lot of taxonomy, the way to perceive the competence can be expressed as well
0 - no knowlege;
1 - can do simple tasks with help;
2 - can do simple tasks alone;
3 - can do all the tasks;
4 -can transmit his know-how;
5 - expert, creation, advances the system
