This study aimed to explore how to characterize the earth science inquiry in schools in terms of science teaching interaction and constructivist teaching practice. The constructivist teaching practices were analyzed with Reformed Teaching Observation Protocol (RTOP) in three aspects including (1) student oriented class implementation, (2) subject knowledge and representation, and (3) classroom communication. Fourteen earth science classes were observed and scored with RTOP. The class was evaluated to be transitional stage in terms of constructivist teaching, e.g., moving toward student-centered teaching practice. Especially, Korean teachers tend to lean their classes more on propositional knowledge than procedural knowledge. To interpret science teaching interactions, an earth science teacher with a RTOP top rank was selected. Her class was then videotaped for detailed analysis. I adopted the analytical framework of communicative approaches and discourse patterns among the five aspects of interactions presented by Mortimer and Scott (2003). It was found that this earth science teacher used more authoritative patterns than the dialogic. In addition, she used IRE discourse pattern more frequently. Interestingly, teachers interacted with their students more frequently in the form of repeated (or IRE chain pattern), that is IRFRF (teacher initiation-student response-teacher feedback-student response-teacher feedback) in the context of dialogic communicative approaches, while simple IRE occurred in an authoritative approach. In earth science classrooms, typical interaction may well be constructed in the form of IRFRF chains to allow students free conjectures and abduction.

In this case study, we investigated teaching strategies of science teacher's teaching in science museum. Two secondary science teachers who completed a teacher training course on teaching in science museums participated in this study. We conducted interviews about their perceptions on teaching in science museum and their teaching plans before teaching. Then, we observed and recorded their teaching practices in the science museum throughout one semester, and collected all of the teaching materials. The interviews were also conducted after every lessons and at the end of the semester. For the analysis of teaching strategies, we used a framework that was revised from the framework for museum practice (FMP). The analysis of results revealed that the teachers understood the significance of planning the activities in a series of pre-visit, during-visit, and post-visit, so that they structured their teaching as continuous activities, not as an one-time event. However, they showed differences in the extent of connecting the activities with the national science curriculum according to their teaching objectives. In addition, there were differences in strategies such as promoting social interaction, evoking students' curiosity and interest, providing students with choices and control, and inducing engagement and challenge depending on each teacher's perceptions and experiences on teaching in science museum. These results suggest that science teacher education for the professional development of teaching in science museum should systematically provide knowledge and experiences on teaching strategies based on appropriate perceptions on teaching in science museum.

The purpose of this study was to analyze the mediating effect of pedagogical content knowledge of science teaching on the relations among child care teachers' burnout, science teaching anxiety, and science teaching efficacy. For this study, questionnaires were distributed to 355 teachers working at child care centers in Jollanam-do. The analysis of data was conducted with SPSS WIN 18.0. The results of this study were as follows. First, child care teachers' burnout lowered their science teaching efficacy, and child care teachers' pedagogical content knowledge, as a mediating variable, reduced the negative effect of child care teachers' burnout on their science teaching efficacy. Second, child care teachers' science teaching anxiety lowered their science teaching efficacy, and child care teachers' pedagogical content knowledge, as a mediating variable, reduced the negative effect of child care teachers' science teaching anxiety as an independent variable on their science teaching efficacy. These findings imply there is a need to boost pedagogical content knowledge during in-service teacher education programs.

In this study, we investigated the relationships among elementary school teachers' perceptions of constructivist science assessment, views on science teaching and learning, science teaching efficacy belief, and the perceptions of constructivist science learning environment. An exploratory factor analysis was conducted to validate the factor structure of the perceptions of constructivist science assessment test. The test consisting of 3 factors with 21 questions in the previous research was reconstructed as one consisting of 2 factors with 22 questions as a result of the factor analysis. A stepwise multiple regression analysis was also conducted to predict the explanatory powers of the variables on perceptions of constructivist science assessment. The results indicated that the perceptions of constructivist science learning environment, views on constructivist science teaching and learning, and personal science teaching efficacy belief were the significant predictors of the perceptions of constructivist science assessment.

This study examined how pre-service elementary teachers' perceptions regarding the learning environment (learning focus/ability-meritocracy/cooperative climate) and achievement goals (mastery/performance-approach/performance-avoidance) in science education courses jointly contributed to their science teaching efficacy beliefs (personal science teaching efficacy belief/science teaching outcome expectancy). A path analysis supported a causal model in which the perception of the learning focus influenced the mastery goal, which in turn influenced the personal science teaching efficacy belief and science teaching outcome expectancy. The perception of learning focus also had a direct effect on science teaching outcome expectancy. The perception of ability-meritocracy influenced personal science teaching efficacy belief via the performance-approach (positively) or, conversely, the performance-avoidance goal (negatively). No link .was deduced from the perception of cooperative climate. The educational implications of these findings were also discussed.

The purpose of this study was to analyze elementary school teachers' teaching style and elementary school students' science anxiety according to teachers' teaching styles for science class. Data were gathered through the teaching style test and the science anxiety test. The teaching style test was taken in 293 elementary school teachers and the science anxiety test was taken in 1,523 elementary school students. The results were as followings: First, elementary school teachers' teaching style for science class were most in provider, expert and least in enabler. Second, elementary school students' science anxiety according to elementary school teachers' teaching style for science class were highest in facilitator and lowest in Enablers. There were significantly differences in science anxiety according to the teaching styles in elementary school. Third, elementary school students' science anxiety increased as grade goes up.

In this study, the relationships among self-directed learning ability, science teaching efficacy beliefs (personal science teaching efficacy and science teaching outcome expectation), life satisfaction, job satisfaction, and other background variables of elementary school teachers were investigated. A survey was administered to 234 teachers from 25 elementary schools in Jeonju. It was found that self-directed learning ability of the teachers was significantly correlated with their personal science teaching efficacy, science teaching outcome expectation, life satisfaction, job satisfaction, and age. A stepwise multiple regression analysis revealed that personal science teaching efficacy, life satisfaction, science teaching outcome expectation, and age were the significant predictors on their self-directed learning ability.

The purpose of this study was to find out and analyze the science teacher's teaching methods. A total of 35 teaching methods were abstracted from the previous studies and the relating literatures. An instrument to measure the frequencies of using methods was developed and then tested to middle school science teachers. The Results of two factor analysis methods were compared. The results are as follows: The instruments's reliablity coefficient(Cronbach ${\alpha}$) was 0.7707. The teaching methods which middle school science teachers have used frequently were represented as the proposing of the learning objectives, the deductive teaching, the experimental activities by teacher's guide, the summarization after explanation, the reading text etc. Also, it was revealed that they have not use the diagnostic evaluation, the formative evaluation, the experimental activities by student's design, the instructional medium. By confirmatory factor analysis, the 1st factor included 13 teaching methods and 2nd and 3rd factor included 9 and 7 methods respectedly. The meaning of 1st factor was interpreted to stimulate student's learning motives. And the other's were about the development of instruction. In exploratory factor analysis factors were overlapped or more fined. These were due to the structure of factors.

The purpose of this study was to examine the effects of teaching-learning programs from the perspective of brain-based learning science. Four units in 5th grade elementary science programs of the Revised 2007 National Curriculum were selected as contents to study. As the brain-based learning science analysis method, equations of the brain compatibleness index (BCI) and contribution degree on the brain compatibleness index (BCICRE) were applied to them. This study showed that there were qualitative and quantitative differences among the analyzed teaching-learning programs through the unit and curriculum. The results showed that hands-on activities like experiments or open inquiry activities improved their evaluation of the teaching-learning programs. From the analyzing, teachers can judge whether each teaching-learning program made considered the brain of the learners. Furthermore, this study can provide useful information to consult of various science teaching-learning programs brain-based learning.
