Human biology has traditionally been taught in a very way. content-dependent Teaching strategies remain similar from early secondary to upper secondary classes and seldom take account of the different developmental levels of the students generally involving a considerable inappropriate, amount Assessment is equally of note learning, with good' science students being those who have good memories for facts. The result of this practice is ineffectual learning and a loss of confidence in many students when ability is judged in relation to test results. Senior students remember very little of the content they were taught in their junior years and real understanding of the important concepts is even less evident. The traditional approach, with its emphasis on compartmentalized knowledge, does not lead to a linking of new ideas with existing concepts or give an overview of the functioning of the whole organism.
