The importance of prior knowledge and assessment for increasing efficiency of the learning processes, especially in ‘problem-based’ powerful learning environments

Does it help one to know how a Chateau Pichon Longueville Baron 1989 looks, smells and tastes in Montpellier, when in fact one is in the process of tasting a Pichon Longueville Baron 1990 at home in a dark and humid cellar at 14 degrees? How important is prior knowledge and assessment for learning in higher education? The present paper provides a theortical background concerning activation prior knowledge, using new assessment methods and applying a new learning process model referred to as powelful learning environments. Recent research has shown that increasing efficiency in learning can be achieved by introducing powerful learning, building on the students' prior knowledge and making use of multiple functions of assessment tools. Different concepts, methods and effects are explained in the paper with regard to their use in real classrooms. A model is outlined for integrating learning, instruction and assessment. Attendants to the session in Montpellier should not only be prepared to taste a good glass of French claret wine, but should also be interested in thinking and working interactively. The presentation itself will elaborate on some of these and will focus practical applications in agricultural higher education.
