As usual in this kind of educational experiment, it was difficult to keep the conditions of the experiment strictly constant and the statistical analysis of the data did not lead to a definitive conclusion. However, we arrived at a general conclusion that it is possible to approach the higher objectives through teaching that uses the open-ended approach. The development of students’ acquired knowledge and skills as components of higher objectives depends not only on native talent but also significantly on the influence of their teachers in furnishing an opportunity to develop and in advising and encouraging the students. We point out, as a background to this finding, that we assumed that evaluating students’ responses to open-ended problems by using the number of different responses and their mathematical quality, as described in later chapters, can be regarded as an evaluation of the higher objectives.
