A 9-years old child uses a printed version of a key to identify aquatic invertebrates.
In the scope of primary schools, the K2N tools have to cope with demanding pedagogy and usability related requirements. The tools are being designed for supporting general pedagogical aims, not just for identification of species. The more general aims include:
- Improvement of cognition
- Generation of problem solving abilities
- Development of team working abilities
- Improvement of knowledge of biodiversity
- Improvement of social skills
- Reinforcement of self-esteem, activation of emotion
- Satisfying the high level of curiosity of children
The KeyToNature keys dedicated to primary school children can be characterised as follows:
- They have a small scale, i.e. they include a small set of species to identify.
- No technical terms, i.e. the language and information provided must respect the age of the children and avoid excessive demands.
- As many pictures as possible.
From a usability point of view, the tools should be as easy as possible to use, respecting the needs of young children (e.g. single choice menus). Navigation, look and feel need to be appealing for this age group. Positive feedback needs to be given on different actions (and also on errors). Most tools have already implemented a help function.
