The purpose of this study was to analyze the processes of observation teaching and the types of observation in elementary life science class. For the purposes of this study, 40 teachers majoring in elementary science education participated in surveys on the processes of observation teaching. In addition, after videotaping the observation classes conducted by three teachers, each teaching in the 3rd to 5th grade, and their one hundred and eight students, we analyzed the processes of observation teaching. As a result, the processes of observation leaching in elementary science class were categorized into 12 stages (motivation, stating the objective, recognizing objects to observe, free and subjective observation, introducing ways to observe, observing by the simple way, introducing additional ways, observing by the manipulative way, making a note of observation, looking over the contents of observation, finding regularities, consolidation). In the types of observation, teachers and students performed mostly simple observing by the visual way. Teachers introduced time-independent/non-compared/whole observing; students concentrated on time-independent/non-compared/particular observing as targets. Thus, students carried out observing in the types of observation that teachers had presented. Consequently, the analysis about the processes of observation teaching can establish an effective teaching program for observing in scientific activities by reconstructing its observing target and suitable topic. The analysis about the types of observation can be applied to set up strategies for improving observation skills.

The purpose of this study was to analyze the responses of pre-service elementary teachers to the plant learning using plant-observation activities and observation journal writings. Thirty pre-service teachers participated in this study. Before and after practicing plant observation and observation journal writing for 11 weeks, pre-service teachers' interest to plants, attitude to plant-observation teaching, and plant-observation teaching efficacy were examined using a questionnaire. Also, the observation journals, reflective journal writings, and interviews were analyzed to investigate their qualitative change. In addition, the pre-service teachers were classified by multi-dimensional scaling and cluster analysis with respect to attitude to plant-observation teaching and observation journal writing, and teaching efficacy. While the pre-service teachers showed significant increase of the interest to plants and plant-observation teaching efficacy, and positive change of the attitude to plant-observation teaching, there was a little difference between gender with more positive effects on females. The positive attitude changes of pre-service teachers included positive recognition about plants and the diversity, increased interest and curiosity about plants, careful observation about nearby plants, and independent learning and positive inquiry with plants. In terms of teaching efficacy, they showed positive change such as enjoyment and satisfaction with plant-observation, confidence as elementary teachers in the future, and recognition about the importance of elementary teachers for plant education. However, the changes were different among the groups classified by attitude to plant-observation teaching and observation journal writings, and plant-observation teaching efficacy.

In this study, KTOP (Korean Teaching Observation Protocol) was applied to teaching practicum for improving pre-service teachers' science teaching. To do this, four pre-service teachers and supervisor teacher observed and analyzed the lessons using the KTOP, and tried to improve he succeeding lessons through collaboration activities. As a result, the pre-service teachers conducted the collaboration activities based on the lesson analysis using the KTOP, therefore it was concluded that the KTOP took a practical role of guidance for improving pre-service science teachers' teaching. And it was found that the collaboration activities using the KTOP helped the improvement of the succeeding lesson, however, more iterative application is necessary for more effective improvement of teaching. Based on the analysis of questionnaire, observation, and interview, it was found that pre-service teachers need to be confident about the use of the KTOP and strive to become a student-centered lesson. And, the KTOP needs to be modified by reducing the number of items and as a more convenient form. Finally, it was inferred that we need to give an effort to help students recognize that learning should be self-directed.

The aim of this study was to explore science teachers' perceptions of good science teaching. To this end, the Korean Teaching Observation Protocol (KTOP), which was developed for the purpose of observing and improving science teaching, was utilized. In the first survey, teachers were asked whether they thought each item in the KTOP was important for good science teaching, the extent to which they implemented these items, and the level of difficulty in implementing them. The second survey asked teachers what they believed to be the reasons and solutions for the KTOP items that they had responded as difficult to implement. The responses obtained from 63 teachers in the first survey and 35 teachers in the second survey were categorized based on the characteristics of the responses. The categorized contents were then summarized and discussed for their features. As a result, science teachers responded that all items in KTOP, except for one, are important for good science teaching. However, it was also shown that the level of execution was low in cases where implementation was difficult. For the 13 KTOP items that were considered important but difficult to implement and showed relatively low implementation level, many respondents (69%) attributed the reason to both students and teachers. However, the most common response (60%) was that the teacher should solve those difficulties. From this, it was found that understanding and supporting teachers, as well as enhancing their competencies, are more important for good science teaching than external factors. We hope that this research findings will help to better understand the specific difficulties that science teachers face in their classes and contribute to practical efforts that aim to address these challenges.

The purpose of this research is to explore the effects of the POE(Prediction-Observation-Explanation) teaching-learning model on the academic achievement and the capability of scientific inquiry of elementary school students. POE teaching-learning model is a three stage process modeling scientific inquiry : Prediction, Observation, and Explanation. This research is to see the effectiveness of the POE method in earth science class by applying this simple practical strategy out of various methods in science teaching with the purpose of improving the capability of scientific inquiry and the academic achievement of learners. The findings of the study are as follows: First, the POE strategy in science teaching-learning was found effective for the improvement of learners' scientific inquiry capability. Second, the POE strategy in science teaching-learning is effective for the improvement of learners' academic achievement in science. The findings mentioned above suggest that using the POE strategy in science class of elementary science education has significant effects on improvement of scientific academic achievement and scientific inquiry capability of learners compared with the general science teaching-learning strategy. It also shows to be highly recommendable for use in science class.

The purpose of this study was to investigate the effects of teaching based on analysis of a hierarchy of the concepts associated with astronomical observation as well as each learner's status of knowledge through analytical methods of the knowledge state. A test instrument was developed to measure high school students' concepts associated with astronomical observation before instruction. The learners' psychological hierarchy associated with astronomical observation that the participants possessed showed the order of 'motion of the earth${\rightarrow}$coordinate system${\rightarrow}$astronomical observation (mechanism of the telescope${\rightarrow}$installation of the telescope${\rightarrow}$observation through the telescope)', and so was the hierarchy of teaching (70.6%). The learners' knowledge state that is supposed to be similar each other in the ability of observing celestial bodies was different even through they scored the same on the concept test. There were cases with the knowledge state well-structured and not well-structured, which suggests that differentiated instruction with appropriate teaching-learning prescriptions be prepared. An analysis of the knowledge state can play the role of both preparing individualized learning prescriptions and formative evaluation. In the unit dealing with astronomical observation of Earth ScienceI, teaching according to the psychological hierarchy of learners rather than the order in which the textbook syllabi were presented scored significantly higher (p<0.05) on the level of concept achievements. This result suggests that the teacher can help students achieve more efficient in learning by analyzing the learner's knowledge state and reordering the syllabi of the textbook in teaching the concepts associated with astronomical observation.

The importance of teaching the nature of science (NOS) has been always emphasized in science education. However, the NOS is hardly taught in elementary science class. We are lacking in the strategies and materials for teaching NOS. So we designed the science drama teaching, and investigated the effects on pupils' perceptions about NOS. The subjects of this study were 185 third graders from a elementary school. The treatment group was provided with science drama lessons and the control group was provided with traditional lecture-type lessons. Their perceptions about NOS were investigated before/after the science lessons and after 3 months following them, and both of two groups were compared. The pretest results revealed that the pupils of both groups were found to have similar views on NOS. Dey had traditional views of the most items except for social construction of theories, mathematical knowledge and decision-making. After science lessons, they tended to change their views toward modem views, but the pupils of the treatment group showed more modem views than those of the control group on the observation, model, social construction of theories, predictions. After 3 months, the pupils of the control group tended to come back to their traditional views, but those of the treatment group showed tendencies that their changed views were kept up on the observation, scientific model, scientific knowledge, scientific methods, decision-making, social construction of theories, mathematical knowledge. Therefore this study suggests that science drama teaching could be one of the effective ways for teaching NOS.

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.
