The trend of research in educational technology, during the last decade, has been to focus on learners and learning. The evolution of the ideas could be sketched in the following way : the initial paradigm was to design Intelligent Tutoring Systems (ITS) as autonomous machines with strong instructional functionalities and some sort of modelling of learners' needs and cognitive characteristics, a second paradigm has been the development of learning environments (eg microworlds) opening to the learner a real space for the exploration and the construction of knowledge. The former has not led to clear success, the later has evidenced serious difficulties (well documented by the Logo literature) and the need to complement the environment by teachers input and guidance. The lesson then, is that if teaching reduced to instruction is not the more successful avenue, the absence of teaching features in a learning environment does not guaranty either the quality of the learning output.
What are the lessons ? Clearly the need to search for a new paradigm which could ensure a better equilibrium between learning and teaching, between human and machines. The common interest of Europe and the US, either in general education or professional training (lifelong learning), to overcome educational difficulties especially in science, mathematics and language learning, together with their common recognition of the potentialities of educational technology, should lead to a fruitful synergy in this area.
The reasons why the learner, either a child or an adult, needs "teaching inputs" are very often hidden as a result of the strength of the emphasis on the constructivist principles of design of learning environments. These needs are especially important with modern environments which are largely distributed and provide a potential access to a huge range of knowledge and information. These reasons could be sketched by the following questions which acknowledge that the learner has in general a low level of control on the events which are on the edge of the learning process in which he or she is involved—unlike the expert problem-solver:

"How to look for something you don't know? "A last question raises a crucial question related to the fact that in many cases learning is related to a willing to get the adequate qualification with respect to a given competence or activity. Indeed, the issue of certification must be considered together with the design of a learning environment, since…
"How to know that you have found what you looked for? "
"How to know that you have learned?"
"How will others know that you know?"These issues, which call for the involvement of teaching (agents) in the learning environment, are even more essential in the case of complex knowledge (as opposed to basic skills).
