It is a big role of the universities of science and engineering to bring up students who can correctly understand the science and engineering, and duly judge the science and technology when they are applied to the society, while young person’s losing interests in science are becoming aggravated. In addition, the problem of NEET(Not in Employment, Education or Training) is a socially serious problem. There are a lot of universities that begin to introduce the career education as centering the universities having liberal arts students. However, the university of science and engineering also starts to introduce the career education. In this paper, the characteristics test is carried out, and the middle repeated questionnaires that ask 22 items about student's states in detail are designed for the career education, and their measurements have been carried out five times a year. This paper analyses and examines the relationship between the educational effectiveness and characteristics of students using a multi-split tree structured method in analyzing the length of attending lectures. When students attend the career design A, how much influence of deepening of "Self-understanding" like my ability and strong point, etc. and "Communications skills” on "View in the future" does the education have, and how do "View in the future" and "Consideration to work" have influence on "University life"? "View in the future" is measured by 3 questions “the clearness of the life design”, ”the expansion of the occupational category” and “ the understanding of necessary abilities in the future”. We design the questionnaires to examine also whether the motivation to the study of the university have gone up, how much study students acquire, how many hours they study per week, with the items that relate with the career. In this paper, we present the complicated interactions of those influencing factors on the educational effectiveness using a multi-split tree structured method with graphical display.

Methodology or methods/research instruments or sources used: In this paper, we use a multi-split tree structured method in analyzing the length of attending lectures, in order to analyse and examine the relationship between the educational effectiveness and characteristics of students. We can present the complicated interactions of those influencing factors on the educational effectiveness using a multi-split tree structured method with graphical display. In this paper, the characteristics test is carried out, and the middle repeated questionnaires that ask 22 items about student's states in detail are designed for the career education, and their measurements have been carried out five times a year. When students attend the career design A, how much influence of deepening of "Self-understanding" and "Communications skills” on "View in the future" does the education have, and how do "View in the future" and "Consideration to work" have influence on "University life"?

In this paper, we analysed and examined the relationship between the educational effectiveness and characteristics of students using a multi-split tree structured method in analyzing the length of attending lectures. From Analytical results, we could understand that cluster 1-1 became a little less than 4.00 about personality trait item h: "aggressiveness", i: "sociability", and its communication abilities are different from cluster 1-2. In addition, there is a difference with cluster 1-1 and cluster 1-2 about a : "intellectual power", g: "active energy" and j: "leadership", and these abilities are needed by group working. Therefore, we understand that students in cluster 1-1 have the characteristic that can wrestle with group working. In this paper, we presented the complicated interactions of those influencing factors on the educational effectiveness using a multi-split tree structured method with graphical display.
