There have been much efforts to reconstruct the science curriculum focusing on Disciplinary Core Ideas(DCI) in many countries such as America and Europe, the most practical effort has been to design a curriculum with learning progressions(LPs). LPs describe stepwise how students can systematically move toward the understanding of more sophisticated ideas or scientific activities and explain in succession the process of understanding the ideas while the students learn. In this study, a LP for ecosystems has been developed, and the developed LP is then evaluated accordingly. The Ecosystem is one of the DCI of the life science in Next Generation Science Standards(NGSS). The development process of the LP was set at step 4(Development, Assessment, Analysis, and Amendment), and developed through an iterative process of sequences. As a result of analyzing the developed LP, an assessment based on the LP provides reliable information to identifying student ability. This study proposes the development process of the LP and its methodological aspects to use Core Achievement Standards, Ordered Multiple-Choice items and the Rasch model. In addition, using the empirically proven LP suggests a way of strengthening curriculum linked to educational content, teaching methods and assessment. Utilizing the proposed development process in this study will be to present the standard into the direction of becoming part of the curriculum. Currently, the state of domestic research for the LP is still lacking. This study determined the development process of the LP and the need to conduct future research on the LPs.

This study is to find a theoretical basis for the effective teaching-learning of the geographical concept through comparing two cognitive pshychological perspectives: Piaget's cognitive development stage theory and Vygotsky's theory with higher mectal function and zone of proximal development(ZPD). Piaget't theory of cognitive development stage has been empirically proved in the spatial concept development and provided a basis for geographical educational psychology. In spite of this contribution, it has its own limitation in that students cannot learn cocepts beyond their cognitive development stage. On the other hand, Vygotsky supposed that concept development has been done by teaching-learning. This study suggests that Vygotsky's theory gives more comprehensive thoretical basis for its effective teaching-learning about the geographical concept development.

The purpose of this paper is to introduce the current studies and research methods about Learning Progressions disseminated to several countries including the U.S. since 2006. It also provides a methodological base to investigate learning progressions in science by introducing a case study of learning progression conducted in Korea. For this study, we described several features of current studies on learning progressions in the U.S., and reported the common ways and sequences employed in examining learning progressions especially with respect to assessment for learning. Learning progressions are descriptions of developmental pathways of learning a topic, in which science knowledge is used in students' engaging in science practices. Each learning progression consists of upper anchor, lower anchor, and intermediate steps that connect both anchors. In investigating a learning progression, researchers usually utilize Wilson's four building blocks of assessment system based on the assessment triangle. This kind of method was also applied in investigating the learning progression for water cycle in this study. We discussed implication and consideration for the future research on learning progressions in science in Korea.

This is to understand the neurological dynamic cognitive processes of math learning based on the abstract mappings( level A2), abstract systems(level A3), and single principles(level A4), which are principles of Fischer's cognitive development theory. Math learning requires flexibility to adapt existing brain function in selecting new neurophysiological activities to learn desired knowledge. This study suggests a general statistical framework for the identification of neurological patterns in different abstract learning change with optimal support. We expected that functional brain networks derived from a simple math learning would change dynamically during the supportive learning associated with different abstract levels. Task based patterns of the brain structure and function on representations of underlying connectivity suggests the possible prediction for the success of the supportive learning.

This study focused on the geographical concepts development and its zone of proximal development(ZPD) through the collaborative interaction. Among the conclusions are: 1) Students who have higher cognitive structure represented the Creator Seoul Metropolitan Area(GSMA) as a geographical concepts, not as a spontaneous concepts. The concepts is developed from concrete facts, subordinate element concept to basic element concept hierarchically. The most difficult concept that the learner should internalize was represented as the basic element concept. 2) Although ZPD of GSMA is individualized, it could be divided into 9 types. The ZPD was developed differently according to the qualitative differences how much more and how systematically represented the geographical concepts. The characteristics shown in this development procedure was that there was a quality change based on quantity extensive.

The purpose of this study was to develop and apply a framework for progression in the professional development and learning of secondary science teachers' teaching practice. The progression in the professional development was modified Pilhee Woo's framework(2010), and in the learning was developed by the researchers. The former included 6 elements and 36 aspects. The progression of each aspect was composed of five level criteria. The content validity is 96.4% and the reliability is .96. The latter was composed of another five level criteria. The content validity is 96.0% and the reliability is .95. Internet-online test and the questionnaire were administered to 203 secondary science teachers who were selected by convenience sampling. The mean level of the progression in the professional development and learning were 2.21 and 2.95. ANOVA, t-test and correlation analysis were conducted to compare differences by the characteristics of teachers. The level of the progression in the professional development and learning was significant difference according to almost all of teachers' characteristics. The level of the progression in the professional development was significantly correlated with the level of the progression in the learning.

The purpose of this study was to examine the structural models in which early cumulative risk factors affect children's language(indicated by expressive vocabularies) and social development(indicated by peer competence) at age 3 thorough their effects on the home learning environment. To examine the hypothesized models, the data of 1,725 families from the second and the fourth waves of the Panel Study of Korean Children was used. Correlation analysis and structural equation modeling were conducted to test the models. First, the cumulative risk factors at age 1 and 3 were highly correlated, implying the stability of the risk factors over time. The more cumulative risk factors at age 1 predicted the lower level of the home learning environment at age 3, which, in turn, was significantly related to both language and social development at age 3. However, the early cumulative risk factors did not directly influence later developmental outcomes. Moreover, the cumulative risk factors at age 3 were directly related to the child's language development, but neither social development northe home learning environment. In addition, the mediational role of the home learning environment (i.e., cumulative risk factors at age 1${\rightarrow}$home learning environment${\rightarrow}$language and social development) was statistically supported. In conclusion, the early cumulative risk factors in infancy indirectly predicted children's development at age 3 through the home learning environment. The practical implications for the early intervention and support for the families with infants who are experiencing multiple risk factors were discussed.

In this thesis, a field experience activity support system is designed and implemented for improving social skills of children with developmental disabilities. The proposed system is designed to allow the students to experience various field activities around their local community. The proposed system has the following characteristics. First, it can improve effectiveness of field experience by providing very practical pre-study information to students. Second, the systems provides very practical and real-world problem-solving abilities rather than providing simple experience and superficial information. Third, the system allows students to change the contents according to their local community environments and purpose of use. Fourth, the system can be used as education for living at home as well as field experience study at schools. After applying the proposed system to students with developmental disabilities, the following positive results are obtained. First, the system have good effect on students with severe developmental disabilities when the system is used for prestudy. Specially those students are highly interested and motivated on study subjects. Second, at real field experience study place, students are well adapted and are very interested in their activities. Third, in the light of post-evaluation after field experience, it is reported that lots of study contents remain in their memory.
