The purpose of this study is to look into self-concept and teaching anxiety of elementary school teachers about inquiry instruction in science class, and investigate correlations among them. For this study, the survey was carried out on 338 elementary school teachers, and the interview was conducted with 5 of them. The results of this study are as follows; Self-concept of elementary school teachers about inquiry instruction in science class was more positive than usual. And the teachers who were male, older and majored in science education showed more affirmative self-concept about inquiry instruction in science class. Teaching anxiety of elementary school teachers about inquiry instruction in science class was less than usual. And the teachers who were male, older and majored in science education showed less teaching anxiety about inquiry instruction in science class. The correlation of self-concept and teaching anxiety of elementary school teachers about inquiry instruction in science class was an negative interrelation. This presents that the teachers, who have more positive self-concept about inquiry instruction in science class, have less teaching anxiety than those who have more negative one. Consequently, teacher training and retraining programs should be developed and conducted by grasping teachers' self-concept and their anxiety, to reduce anxiety about inquiry instruction in science class.

The purpose of this study is to compare the elementary science curriculum and textbooks of Korea, the United States, Japan, and Singapore to know how the contents on particulate concept of matter is introduced and expressed. In Korea, particulate concept of matter was adopted as a term for 'molecules' in the 3rd through 6th curriculum, and the term for 'particles' was adopted in the 2009 revised curriculum. In the United States, NGSS adopted the term 'particle' in fifth grade. Japan presented the concept of 'particle' as a core concept of matter in the commentary, and the expressions 'particles' were being introduced in the textbooks. But it did not cover particulate nature of matter at the elementary school level in Singapore. An analysis of elementary textbooks in Korea, the United States and Japan except Singapore showed particulate expressions in 'dissolution', 'state change of water', 'gas pressure and volume', 'combustion and extinguishment' units. Korean textbook was only being introduced in 'dissolution' and 'gas pressure and volume', but in the textbooks of Japan and the United States, water was expressed as particles in 'state change of water' unit. Discussion and implication on the introduction of particulate concept to elementary science curriculum and textbooks were suggested based on the results.

Many elementary school students have misconception related to dissolution and solution. Moreover, they usually fail to apply the results of the experiments in their science classes to their everyday life, and also have low science achievement. Therefore, they are not interested in science, and sometimes some of them are even afraid of it. The purposes of this study is to investigate the effects of concept mapping activity on science achievement and attitude. In addition, this study also aims at presenting the teaching and learning method of utilizing concept maps in order to have the students form correct concepts. The subjects were classified into two groups one group is composed of thirty-seven students (experimental group) who were participated in concept mapping activity, and the other is composed of thirty-eight students (comparison group) who were participated in the traditional teaching method. The major findings of this study are as follows: First, the concept mapping activity has a positive effect on improving students＇ science achievement. Second, the classes using concept maps have a good influence on forming students＇ science attitude.
