This study focuses on the fact that students and teachers commonly have difficulty in 'selecting the topic' in many activities including student-led research that is conducted from topic selection to the drawing of conclusion. The purpose of this study is to develop a manual for science teaching research. The instructional manuals of 4 stages were developed based on practical knowledge that can be implemented in the actual class through previous research and literature. Each stage is composed of , , , and . In the third stage, students are expected to find scientific questions and develop them into research topics through detailed class research on newspaper articles, scientific magazines, traditional knowledge, proverbs, daily life, and textbook experiments. In the experimental group, the final research topic was selected through a variety of sources such as textbook experiments, proverbs, YouTube images, newspaper articles, individual WHY NOTEs, and understood the conditions of the scientific research topic and expressed the variables in the research title. However, in the control group, some students did not consider the research scope of the selected research subjects to be specific or not to be able to study at their level. As a result of giving the students as much autonomy as possible, many groups did not fully understand the previous research and submitted it. Based on the results of this study, it can be concluded that development and use of a 'topic selection stage' centered practice manual for general high school teachers would not only improve the students' abilities to discover solutions to scientific questions, but it will also help shift their attitudes towards science in a positive direction.

The purpose of this study is to identify the types of essential inquiry activities presented in elementary science textbooks for grades 5-6, and to find out what difficulties teachers have in the actual teaching process. To this end, the essential research activities presented in the textbook were analyzed into six types: experimentation/observation, investigation/discussion and presentation, data interpretation, discussion/discussion, simulation activity, and expression. In addition, 108 elementary school teachers were investigated for the suitability of inquiry activity achievement standards, suitability at the student's level, student interest, and difficulty in teaching instruction. To summarize the research results, the most frequently suggested type was the experiment/observation type, followed by simulation activity type and data interpretation type. It was analyzed that there was no discussion/discussion type in the 5th grade textbooks, and the 6th graders did not present research activities that correspond to the research/discussion/presentation type and the expression type in the textbook. In the results of teachers' responses to the suitability of achievement standards for inquiry activities presented in textbooks and the suitability of the student's level, 5th graders showed lower average scores than 6th graders, and showed similar average scores in student interest and instructional difficulty. Also, it was confirmed that improvement was required for a total of 17 inquiry activities. Specifically, teachers responded that they had difficulty in guiding inquiry activities when the experimental results did not appear as intended in the textbook, when students' interest in inquiry activities was low, and when students and teachers had low understanding of related science concepts. Teachers pointed out practical problems such as difficulties in long-term observation in astronomy-related units, and students in upper elementary school not actively participating in dynamic play activities.

We investigated the cognitive frame of high school students and inservice high school science teachers about effective teaching method, and we also explored how they understood about the teaching methods suggested by the 2009 revised Science Curriculum. Data were collected from 275 high school science teachers and 275 high school students. We analyzed data in terms of the words and the cognitive frame using the Semantic Network Analysis. The results were as follows. First, the teachers perceived that an activity oriented class was the effective science class that helped improve students' problem-solving abilities and their inquiry skills. The students had the cognitive frame that their teacher had to present relevant and enough teaching materials to students, and that they should also receive assistance from teachers in science class to better prepare for college entrance exam. Second, both students and teachers retained the cognitive frame about the efficient science class that was not reflected 2009 revised Science Curriculum exactly. Especially, neither groups connected the elements of 'convergence' as well as 'integration' embedded across science subject areas to their cognitive frame nor cognized the fact that many science learning contents were closed related to one another. Therefore, various professional development opportunities should be offered so that teachers succinctly comprehend the essential features and the intents of the 2009 revised Science Curriculum and thereby implement it in their science lessons effectively.

The purpose of this study is to critically review the skill-based approach to scientific inquiry in science education and to explore the meaning of science practices that are emphasized in recent science education reform movement. An extensive review of relevant literature was carried out, and the results were summarized according to the detailed themes of the study. In the skill-based approach of which Science-A Process Approach (SAPA) is a representative example, science process skills were presented as hierarchically connected with one another, they were believed to be transferable or generalizable, and science learning through discovery was stressed. These points of view are, however, contradicted with those of the modern philosophy of science which suggests the theory-laden nature of using the skills. The skill-based view has also been criticized by the fact that the use of inquiry skills is content-specific or context-dependent and that science theories or principles cannot be discovered by induction. In contrast, the recent view understands science practices holistically, emphasizes the diverse ways of doing the practices which vary with different contents or contexts, and considers student ideas importantly in the science classroom. The findings of this study can contribute to the development of a new science curriculum by providing implications for establishing a consistent view on scientific inquiry.

The purpose of this study is to develop and evaluate the effect of a teaching-learning plan for teaching about Hanbok to high school students. Results of this study are as follows. First, learning themes in the teaching-learning plan were selected so that the learning objectives could be achieved by gradually advancing from understanding to exploring and finally practicing. Teaching and learning activities for conceptual classes focused on students' exploration and thinking processes. For Making project, students were asked to complete a group artwork using characteristics and images of Hanbok while applying creative thinking and collaboration. Second, the teaching-learning plan was evaluated by comparing students' pre- and post-test scores of knowledge in, perception of, and attitude toward Hanbok; and by analyzing students' journal of reflection and teacher's observation diary. The mean scores of high school student' knowledge, perception and attitude of the post-test were significantly higher than those of pre-test. The content analysis showed that students gained extensive knowledge toward Hanbok and found new values through their classes. Making practices with generation of creative ideas and collaboration has been effective in training a self-directed and a creative learner.

The purpose of this study is to investigate the perception on video material making and the effect on science teaching ability after conducting non-face-to-face teaching material making activity for elementary pre-service teachers. This activity consisted two processes. One is that elementary pre-service teachers conduct inquiry, understand related science concepts, analyze science textbooks and then make video material. The other is that they watch video materials produced by colleagues. This study was conducted on 89 elementary pre-service teachers for 8 weeks. After this activity was completed, the perception on video material making and the effect on science teaching ability of elementary pre-service teachers were investigated, and the results were analyzed. In the process of making and watching non-face-to-face teaching materials, elementary pre-service teachers showed positive results in teaching-learning, video production, and emotion and attitude toward video material making. In addition, it was found that they improved their science teaching ability through this activity and were very satisfied with this activity. However, they also mentioned several disappointments such as exclusion of learners' right to self-determination, lack of various communication channels, and errors in content of materials. This suggests that if these problems are solved, non-face-to-face classes can also be a good form of class.

In this study, pre-service science teachers' reflective thinking in their journal writing was investigated. To do this, the authors used pre-service science teachers' journal writing abilities, wherein they not only reported data and result formally, but also wrote their feelings and reflections about an inquiry-based physics experiment they performed. Pre-service science teachers' writings were decomposed into sentences and each sentence was analyzed into a framework with 4 dimensions: knowledge, procedure, orientation and attitude. Reflective thinking in knowledge dimension included reflection on what they know before the experiment, what they still do not know and what they learned from the experiment. Reflective thinking in procedure dimension included recalls of experiences about general experimental procedures and specific experimental skill. Reflective thinking in orientation dimension included their views about the nature of science and science teaching and learning, and reflective thinking in attitude dimension consisted of interests, motives and values about the experiment they performed. While there were some variations in frequency distribution of reflective thinking by the topic of experiments, pre-service science teachers' reflective thinking in journal writings revealed their metacognition on their knowledge and learning, epistemological belief about science and science learning, and affective domain related to experiment. This study can infer that such kind of writing with 'their own language' in an informal way followed by formal 'scientific' reports in a scientific experiment has a significance not only as a mediator representing reflective thinking but also as an instructional activity to facilitate reflective thinking in science learning and teaching.

This study aims to discover how three-year-old children to search for existence and its meaning, while they participate a programme, 'discourse among children through books' as a way of resolving curiosities. Data were collected between April 2, September 10, 2010 and the collected data included teacher's class records, pictures, discussion notes and interview materials. The results showed that 'discourse among children through books' follows steps in a process. The steps include: Deciding a topic that children should search for, choosing an appropriate book to resolve children's curiosities, spending some time for discoursing among children by using pictures in the book, and sharing what they had understood. Through this process, a pre-school teacher met with children who were full of abilities, ideas and motivation to explore with a little assistance. The pre-school teacher was able to overcome preconceived ideas that informational books could be difficult for children, and experienced various lessons, while the children led their own learning. It represents that the activity, 'discourse among children through books' can be a children centered inquiry learning teaching strategy, because the informational books ensure that the children gain knowledge and are actively in cogitation.

The purpose of this study is to verify the effectiveness of the Development-oriented model (Discovery-Design-Development: DDD) for developing students' Computational Thinking skills in software education. DDD is a class model that learns the process of developing SW to solve real-life problems through three stages of Discovery, Design, and Development. In order to verify the effectiveness of the DDD, first grade students at G university who did not have SW education class were tested. As a result, the students who experienced SW development through DDD maintained the learning motivation of SW education before and after, especially the confidence area increased significantly. In addition, students also noted that the Design phase was particularly helpful in improving CT abilities and the DDD was a significant help in understanding of decomposition and algorithms.

Concept mapping is a device for representing the conceptual structure of a subject discipline in a two dimensional form which is analogous to a road map. In the teaching and learning of earth science, each concept depends on its relationships to many others for meaning. Using concept mapping in teaching helps teachers and students to be more aware of the key concepts and relationships among them. The purpose of this study is to investigate the effect of the use of concept mapping on science achievement and the scientific attitude in ocean units of earth science. The results of this study are as follows; first, the science achievement of a group of concept mapping teaching is significantly higher than that of the group of traditional teaching. Also, when the achievement levels are compared among different cognitive ability groups, the effect is more significant in mid or lower level student groups than in high level groups. The use of concept mapping is more effective when the concepts have a distinct concept hierarchy. Second, the scores of the test of ‘attitude toward scientific inquiry’ and ‘application of scientific attitude’ of the group of concept mapping teaching are significantly higher than those of the group of traditional teaching, whereas the scores of the test of ‘interest in science learning’ of concept mapping teaching is not different from those of group of traditional teaching. Third, the survey on the use of concept mapping shows a positive response across the tested groups. The use of concept mapping is more beneficial in fostering the comprehension of the topic. A concept map of student's own construction facilitates the assessment of learning, thus promising the usefulness of concept mapping as a means of evaluation. In regard to retention aspect, concept mapping is considered to be more effective in confirming and remembering the topic, while less effective in the aspects of activity and interest. In conclusion, the use of concept maps makes learning an active meaningful process and improves student's academic achievement and scientific attitude. If the concept mapping is more effectively as an active teaching strategy, more meaningful learning will be attained.
