Teaching of Biology to Students of Different Curricular Backgrounds

Most teachers in charge of teaching biology as a subject of general educational course in colleges are usually confronted with the inevitable problem, namely teaching a mixture of students in terms of their background knowledge: one group of students includes those who have already had fundamental knowledge of biology to a considerable extent while the other involves students without such a background. The best solution of this problem would be to provide two different levels of lectures after segregating them into two groups. Such reform, however, cannot be done immediately. Under these circumstances, I herein describe a possible way of lecture that would be acceptable to both of these two groups. The lecture of this kind has actually been put into practice for these two years. This article deals with: 1) the analysis of the relationship between the curricular background of students and their actual scholastic ability; this analysis is at the same time essential for setting the level of lecture to be given 2) a possible manner of lecture which would be acceptable to most students irrespective of their background knowledge of biology, and 3) the evaluation of such lecture on the basis of the marks they finally got and the results of a questionnaire survey
