What prior knowledge is required of the teachers before using FOSS?
The prerequisites for using FOSS are minimal. Virtually no science background is required, but, of course, the more background a teacher has, the more comfortable he or she will be, because the territory will be somewhat familiar. Beyond that only the basic qualifications of all teachers are needed: love for children and sensitivity to their individual needs, willingness to learn new tricks, passion for hard work, curiosity about the mysteries surrounding the process of learning, the irresistible need to answer the calling to teach.
