Activity materials in textbook could facilitate students' oriented self-help learning. The purpose of this paper is to find out characteristics of activity materials in the housing area of middle school Technology and Home Economics and teacher's perception of them. The data were collected from 253 middle school teachers who had ever taught the housing unit in any of 6 textbooks. The results showed that the number of activity materials were differed by the characteristics of the materials such as type of materials, feature of non sentence materials, and type of activity, depend on authors as well as textbooks. In general, teachers interests in the materials were higher than those of students even the trends of the interests were the same. Adequacy of activity contents and related knowledge of teachers were higher than adequacy of level. Teachers thought time and extra search beyond class were barrier to full the interests of students. Further research is suggested to find out whether higher interests in the materials are related to the higher activating rate of them.

This current study sought to investigate effects of in-service teachers' achievement goal orientation, organizational citizenship behavior on job-satisfaction and to discuss the improvement of early childhood teachers' achievement goal orientation and organizational citizenship behavior. A total of 178 teachers participated in this study and completed questionnaires. To analyze the data, Pearson's correlation and hierarchical multiple-regression analysis were used. The results were as follows. Firstly, relatively correlation existed between teachers' achievement goal orientation and job satisfaction. Particularly, mastery-approach orientation, performance-approach orientation showed the relatively high correlation with job satisfaction and its sub-scales. Also, teachers' organizational citizenship behavior had relatively positive correlation with their job-satisfaction and its sub-scales. Secondly, teachers' achievement goal orientation and its sub-scale had 38% significant effects on their job-satisfaction. And teachers' organizational citizenship behavior appeared to have 8.6% influence on job-satisfaction.

In this study, the contents of the electron transfer model presented in the 4 chemistry I and the 4 chemistry II textbooks of 2009 revised curriculum and 9 chemistry I textbooks and 6 chemistry II textbooks of 2015 revised curriculum were analyzed in the viewpoint of model's Ignorance. In addition, 3 questions were developed to find out whether 24 pre-service teachers were perceived of the Ignorance of the electron transfer model. As a result, Most textbooks explain the redox reaction of covalent bond substances, which is an inconsistent context of the electron transfer model, with mixing oxidation number change and electron transfer or with electron transfer. In addition, the change to the development and use of the model emphasized in the 2015 revised curriculum was not clearly revealed in the curriculum comparison. Most pre-service teachers incompletely perceived or did not perceive Ignorance of the electron transfer model. Only 1 pre-service teacher perceived Ignorance of the model. In conclusion, the textbook description needs to be improved so that Ignorance of the model is revealed when the textbook describes the inconsistent situation of the electron transfer model. And through the education for pre-service teachers, it is necessary to provide an opportunity for pre-service teachers to perceive Ignorance of the electron transfer model.

The purpose of this study is to investigate the effects of job satisfaction and life satisfaction on teacher-children interactions in kindergarten teachers. The tests of Job satisfaction scale, Life Satisfaction scale, Teacher-Children Interactions scale were administered to 320 public and private kindergarten teachers located in Gyeonggi-do, Gangwon-do. The statistical method employed for data analysis was Pearson's correlation analysis and multiple regression analysis. The results of study were as follows. First, the higher factors of job satisfaction (the teaching consciousness, development, innovation, autonomy, fellowship, and reward), the higher the teacher-children interaction. The higher the workload, the lower the verbal interaction between teacher-children. Second, the higher the life satisfaction of kindergarten teachers, the higher the emotional, verbal, and behavioral interaction between teachers and children. Third, the relative influences of the predictors on the overall interaction between teacher and children are life satisfaction (β=.24), development (β=.22), and fellowship (β=.16) and the explained variance are 25%.

In this study, we investigated the changes in beginning chemistry teachers' teaching practice without mentoring program and after the implementation of mentoring program. Participants in our study included two chemistry teachers who have less than one year of teaching experience and three mentor teachers. We collected data such as video recordings of teacher's classes, interview, and recordings of mentoring after each class. The results show there were slight changes in teaching contents, teaching procedure, and explanation method without mentoring. On the other hand, there were a lot of significant improvement in classroom environment, teaching contents and teaching procedure, teaching-learning techniques, questioning and feedback, and explanation method after mentoring has been implemented. However, there were no easy changes in the teaching style, understanding of students, and ways of interaction with students in connection with teaching purposes. Based on the results of this study, we explored the possibilities of instructional improvement through mentoring on beginning chemistry teacher's teaching practice. Therefore, we consider that more systematic and long-term mentoring is necessary to improve professionalism in teaching beginning teachers. In particular, we propose mentoring programs reflecting the individual needs of beginning teachers.
