An evaluation method is developed which is applicable to teachers' training from the view point of speaking skill as teacher's behavior. Speaking skill mentioned here can be refered to phonetic expression technique or a way of speaking" as a more ordinal expression. In general, as reading a passage with or without intonations makes difference in listeners' impression, we select the evaluation terms regarding the point. The development is done as follows. (1) The speeches of experienced teachers and several trainees were recorded in the digital method. (2) Letting subjects listen to the records, selecting terms on each of which the speech of experienced teacher differs from that of trainees, then we regard each term as evaluation item. (3) In teachers' training, it is necessary to feedback aggregated result of the evaluation immediately and let the trainee know it. So, we adopt radar chart from the viewpoint of easiness of looking at and express the result on it visually. Then we discuss an example of the administration of the evaluation above using the method.

In instructional design, designers (or teachers) choose an optimum educational media (or educational system) adaptive to the learners' abilities. Although instructional design has been recognized as one of the important teachers' activities thus far, they left most of it to their individual subjectives. In order to perform the design in an objective way, a new mathematical method is proposed here to discriminate if the concerned educational system will be effective to learners on not. It is based on the use of linear discriminant analysis. However, when we apply it to the discrimination on education, the conventional method is not always appropriate to the field of education because many educational events are fuzzy, thus it requires refinement. From the point that the author regards the fuzziness proper to education, in order to aid teachers' instructional designing in an objective way, this paper presents a new logic which fixes linear discriminant function, the equations of error probability and Maharanobis' Generalized Distance considering the fuzziness.

In view of educational technology, we will make here a report on an education-material graphics which supports the development of sheet-type education materials such as transparency materials, instructional materials and the like. In science education there are many cases where diagrams used resemble if the disciplinary fields are analoguous with each other. Especially, with respect to demonstration experiments, there are not a few cases where a certain limited number of diagramatic units are combined variously and after modifications a diagram can be completed approximately. Based on these diagrammatic characteristics, we determine the graphic functions and definite the figure-data constrution so as to increase the productivity of material development. In this study, we also derive diagrammatic characteristics in science instructional materials mainly from chemical experiment models and determine the design criteria of education-material graphics.

This paper discusses the characteristics of consciousness structures as to the training of a turning lathe. For this purpose, a consciousness survey is forwarded to the trainers and the trainees. From the answered results, we make consciousness structures for each group, and then compare them. By comparing the characteristic of the trainees with that of trainers, it got clear that the trainees look more interested in worker's behavior such as cutting than the phenomenon on lathe such as heat or vibration, and so forth.
