The Earth Systems Perceptions about Water Cycle of the Elementary Pre-service Teachers
Jeong, Jin-Woo ; Kim, Yun-Ji ;
Journal of Korean Elementary Science Education, volume 27, issue 4, 2008, Pages 319~327
The goal of this study is to examine the perceptions of pre-service teachers that directly affect the concepts and ways of the consideration of Earth systems by students studying the water cycle. A concept sketch method was applied to a survey involving 131 pre-service teachers. The survey was designed to analyze the perception of subordinate concepts of Earth systems from the applied components of the water cycle process and to code the applied concepts with components of the water cycle to the subordinate concepts of Earth systems that were the Hydrosphere, the Atmosphere, the Geosphere, and the Biosphere. The survey was designed to examine the perception of the water cycle from the perspective of Earth systems. The recognition by pre-service students was largely confined to components of the atmosphere and the hydrosphere. With regard to the water cycle process, all subjects surveyed recognized precipitation, and most of those expressed recognition of evaporation and condensation. Many of them recognized the surface flow, while they scarcely expressed knowledge of the underground flow.

Journal of Korean Elementary Science Education, volume 27, issue 4, 2008, Pages 328~340
The purpose of this study is to find out the effects of a science drama on elementary students' science attitudes. To this study, the survey measured science attitudes conducted to the experimental group(N=33) and the control group(N=33), and it was interviewed to them after their science drama. The interview was recorded to make a transcript, then used to complement the results of sub-domain analysis. The results were as follows: There was a statistically significant difference in curiosity and creativity regarding scientific attitude, and interest in science and appreciation of scientist regarding attitudes towards science. Though there was no statistical significance in the other domain of science attitudes, we confirmed that students' science attitudes was changed more positively and meaningfully by the analysis of the interview. Based-on this study, we suggested the implications and the following studies.

Journal of Korean Elementary Science Education, volume 27, issue 4, 2008, Pages 341~355
The purpose of this study was to analyze the measuring abilities of elementary school students by using a microgenetic method. The participants were seven elementary students in the fourth grade. To analyze their measuring abilities, students attended three physical quantities measuring tasks such as length, volume, and time task by six times. Results were as follows. First, in the measuring length task, students selected appropriate measuring instruments but they didn't consider measuring amounts. And as their measuring experience increased, they desirably improved management abilities of measuring instruments. In the measuring volume task, they dealed with measuring instruments, but not very well. And these tendency were maintained. In the measuring time task, they were not measure exactly. Second, as their measuring experience increased, their ability to read the scale marks improved. However, they had difficulties in estimating the volume between scale marks. Results indicate that, elementary students need to basic education about measuring instruments, their usage, and scale reading ability for their science experiment courses in schools.
An Analysis of Sequence of Earth Science Content in Elementary School Curriculum in Korea and the U. S.
Suh, Ye-Won ;
Journal of Korean Elementary Science Education, volume 27, issue 4, 2008, Pages 356~370
The study aims to explore sequence of earth science content in elementary school science curriculum in Korea and the U.S.. The analysis is focused on a) general content structure of earth science part; b) concept relationship between grades in the specific field of 'geology'; c) longitudinal connection of concepts and content in 'geology.' The findings are as follows. First, earth science curriculum content in Korea is structured according to sub-scientific disciplines centering on not science concepts but topics or inquiry activities whereas the U.S. curricular content is organized through integrative earth science topics with basic concepts and sub-concepts. Second, it is a common feature that basic concepts are interrelated to sub-concepts in all grades in both countries. However, basic concepts are scattered all over the grades, presented in a linear pattern in Korea while those are provided together in 3rd grade and repeated with extended concepts in a spiral structure in the U.S.. Last, it is not clear how concepts and content are longitudinally connected between grades in Korean curriculum. On the contrary, concepts and content in the U.S. curriculum have a strong longitudinal connection between grades with conceptual hierarchy. Such results indicate that Korean elementary school science curriculum would limit students' comprehensive understanding of science concepts through grades. The study suggests Korean science content should strengthen interrelationship among concepts as well as longitudinal connection between grades, in order to achieve the ultimate goal of science education, 'scientific literacy'.
Perspective Primary Teachers' Explanations of Liquid-State Phenomena
Noh, Suk-Goo ;
Journal of Korean Elementary Science Education, volume 27, issue 4, 2008, Pages 371~384
The purposes of this study were to investigate perspective teachers' conceptions of liquid-state and get implications for the direction of science curriculum or professional development. The instrument was composed of seven questions focusing on aspects of liquid-state phenomena. The results showed that the participants have various alternative concepts about liquid-state. The problem revealed in almost every question was their macroscopic explanations for the phenomena. In addition, it appeared that the participants seemed to understand phenomena in terminology level, but they didn't know basic reasons or fundamental concepts about the phenomena. It is required to change the curriculum or instructional methods in secondary school and teacher education programs to anchor the scientific concepts on molecular or microscopic level.
The Development and Application of the New Model of Moon Phases
Chae, Dong-Hyun ;
Journal of Korean Elementary Science Education, volume 27, issue 4, 2008, Pages 385~398
The purpose of this study is to understand the effect of The Model of Phases of the Moon on conception changes for preservice teachers. The researcher interviewed two preservice teachers under the agreement with them on their participation in the research just before he performed a class using The New Model of Phases of the Moon. The post-interview with the same content as the pre-interview was preformed one month later. The main content of the interview is as follows; 'Explain the shape of the Moon by drawing it.', 'Explain the relative different position among the Sun, Earth, and Moon depending on phases of the Moon by drawing them.', 'What do you think of the cause of phases of the Moon?', 'Draw a picture to explain why we always see only one side of the moon.' The results of the research are as follows. First, the class with New Model of Phases of the Moon was able to perceive the relationship of Sun, Earth, and Moon in three-dimensions rather than in two-dimensions and it helped to change their misconception that the Moon's shadow causes the Moon's shape. Secondly, the class with New Model of Phases of the Moon helped preservice teachers understand better the different positional relationships among the Sun, Earth, and Moon depending on the Moon shapes. Third, the class adopting the New Model of Phases of the Moon help preservice teachers form scientific conceptions on the causes of phase change of the Moon. Fourth, the class with the New Model of Phases of the Moon is not appropriate for explaining the reason why only one face of the Moon is seen. Based upon the results above, the researcher realized the limitation of this model and suggested that this model would help learners understand phase change of the Moon and increase space perception ability.

The purpose of this study was to develop performance assessment materials of scientific inquiry skills on 62 scientific activities in elementary science textbook for third and fourth grades. For this study, a total of 318 elementary teachers were sampled and surveys were carried out to examine the status of performance assessment of scientific inquiry skills in school. The classification system of assessment methods by Hart(1994) was also analyzed to create assessment strategy of scientific inquiry skills for elementary school students. Based on the quantitative data analysis, literature study and existing performance assessment materials analysis, performance assessment materials were developed and applied to science classes for third and fourth grades. Teachers and students were interviewed after the classes for asking about merits and improvements and the performance assessment materials were revised.

The purpose of this study was to investigate and analysis the elementary teachers' and students' views about the difficulties in teaching and learning in geology units of elementary school science. For the purpose of this study, semi-structured interviews were conducted individually with seventeen elementary teachers who have serviced more than three years, and with sixteen elementary students located in Cheongju City. The interview questions were developed through Seidman's step to acquire a reliability in the interview data with triangulation, then in-depth interview questions were modified and completed through pre-interview after constructing the trustworthiness of interviewees. In-depth interviews were performed in applying the analytic induction method and the interviews were recorded. From the interviews, we found that elementary teachers' views about the difficulties in teaching geology units; teachers' inner difficulties, the difficulty of lab activities, the problems of rock samples, the problems of curriculum in geology units, the difficulty of the geological feature, the problems of the cramming education, the lack of the opportunity for the speciality, and so on. And the students have the views about the difficulties in learning geology units; the difficulty of the unit contents understanding, the problems of learning by heart, the lack of the interest, the lack of materials, the problems of rock samples, the difficulty of the field learning, and so on. Based on the results, the study suggested that an interesting lab activities should be included in the geology units and taught in the geological field trip to help elementary school students more fully comprehend contents of the geology units.
