Science, Mathematics, Engineering, and Technology (STEM) integrated education has been spotlighted as a new approach for promoting students' conceptual understanding and supporting their future career in STEM field. There is increasing evidence of the positive impact of using a whole design process that can be an example of STEM integrated activities to improve students' conceptual understanding and problem solving skills. However, there is a lack of information on how teachers should accomplish science and engineering integration activities in their classroom and what process they should pay attention. To answer this question, we research the relationship between an design process and students' conceptual understanding using an engineering design activity, called 'Save the Penguins', and study on how each step in an engineering design process in this activity enhance students' conceptual knowledge in science. We found that testing their prototypes and discussing with their peers were the most important process for students to understand and apply science concept for their design, even though the whole engineering design process (demonstration about radiation, discussion about examples in our lives, and testing and reviewing their prototypes, and making final design) helps the students understand the scientific concepts.

The purpose of this study was to explore the possibility of implementing 'responsive teaching (RT)' in elementary school science classrooms. A review of relevant literature yielded a tentative framework of RT which consisted of three characteristics of RT and example practices for each characteristic. The RT framework was used to analyze elementary science lessons on the topic of the transpiration in plant leaves. The data sources were audio recordings of three $5^{th}$ grade classrooms which included both the whole-class instruction and student group activities. The data were examined through collaboration between the teacher who had taught the lessons and a university-based science education researcher. It was revealed that the implementation of RT was limited when the teacher's intervention was focused on completing tasks; when it was out of the contexts of student activities; when the teacher provided earlier what students were supposed to find out by themselves; and when the teacher's comments were evaluation-centered. By contrast, the implementation of RT was made highly possible when the teacher's intervention induced an intellectual debate among students; when the teacher negotiated meanings with students; when the teacher connected what students shared to scientific knowledge; and when the teacher prompted students to solve a new problem. Implications about implementing and studying RT were discussed.

This study explored practicing elementary school teacher's beliefs of scientific inquiry and scientific inquiry teaching methods. Defining teacher's beliefs as a broad construct, we tried to examine the teachers' understandings about the scientific inquiry and scientific inquiry teaching method. This study drew on interview data from 10 elementary teachers in busan and changwon area of korea. Conclusions of this study include; First, we found that elementary teacher's beliefs of inquiry were represented variously. And they considered that inquiry is the important goal of science education. They though that the goal of science education is development of Scientific inquiry skills, Scientific thinking skills, development of Creativity and problem solving ability, increasing interest about science, understanding of the basic concepts of science and apply of real-life. second, most of the teachers though that Scientific inquiry is scientists activities, they defined 'the process of creation of new knowledge', 'the process of deriving theory', 'solving process of intellectual curiosity', 'Problem-solving process'. third, they considered that teaching method of scientific inquiry is open inquiry activities. however, they thought that there are many difficulties to actually apply. Understanding teachers' beliefs has implications for both the enactment of inquiry teaching in the classroom as well as the uptake of new teaching behaviors during professional development, with enhanced outcomes for engaging students in Science.

Assessing students' knowledge can be a challenging endeavor, as researchers attempt to capture the full complexity and potential development of children's ideas. In this study, the Dynamic Science Assessment (DSA) method (Magnusson, Templin, and Boyle, 1997) was employed to investigate 9-12 year old students' understandings of light, while engaging in multiple tasks with a flashlight with various reflectors and mirrors. The results showed that DSA was effective in providing an opportunity to establish a Zone of Proximal Development, in addition to diagnosing a student's prior understanding. Throughout the interview, a student showed a conceptual model of light as being a solid single entity whose shape can be determined by the shape of the casing of a flashlight. However, as DSA provided phenomena that could not be explained by his unitary model, the student began to re-examine his original conceptual model, and attempted to revise it. This study addressed how Dynamic Science Assessment can help us better understand, not only students' current state of understanding, but also a potential development of understanding in their ZPD. In that sense, this study argues that we should pay more attention to the instructive role of classroom assessment that can promote and support further development of students' deeper understandings.

The purpose of this study was to seek strengths and weaknesses from analyzing Korea and U.S. science textbooks in terms of general structural features, contents, cognitive levels of questions and the purpose of questions used in science textbooks. This provided insight into improvement of textbooks that can effectively assist teaching and learning. To investigate organization of unit in textbooks in-depth, the evolution unit was selected and scrutinized as one example. The results showed that the number of pages, activities, vocabulary words, and vocabulary lists are considerably different between Korean and the U.S. Commonly, U.S. textbooks were more laden with information and lacking in coherence than those of the Korean textbooks. The findings on the cognitive levels of questions showed that the majority of questions in both nations are concerned with knowledge. However, the difference between the two nations is great in the ratios of analysis, synthesis, and evaluation questions. Questions are concentrated in review section (45% of Korean and 60.6% of U.S.) in textbooks. It suggested that well-planned questions in a review section can provide the basic guidance for strength in a science classroom.
