Journal of Korean Elementary Science Education, volume 27, issue 1, 2008, Pages 1~8
The purpose of this study was to analyze students', preservice teachers and inservice teachers' images of scientists. For the purpose of this study, we selected 711 people. The results generally was showed the students, preservice teachers and inservice teachers have the stereotyped image of scientists. When we group the subject of investigation as elementary-school students, middle-school students, high-school students, preservice teachers, inservice elementary-school teachers, and looked into whether there were meaningful differences among them by the method of ANOVA, we could see the meaningful differences (p<0.05). And also elementary-school students showed the meaningful difference from other groups when examined on the

Journal of Korean Elementary Science Education, volume 27, issue 1, 2008, Pages 9~22
The purpose of this study was to investigate the type of classification criterion and the characteristic of classification strategy that appear in pre-service elementary teachers' classification activity. The 4 tasks were developed for classification activity; button as a real things that attribute is prominent, shell as a real things that attribute is less prominent, snow flake as a picture cards that attribute is prominent, and galaxy as a picture cards that attribute is less prominent. The 5 college students who major in elementary education were selected. Data were collected by interview with participants, participants' classification recording paper, investigator's observation of participants' action observation, and videotaped that record participants' subject classification process. Result proved in this study is as following. First, pre-service elementary teachers used 4 qualitative classification criterion of feature, random field, image and secondary property, and used 2 dimension classification criterion of space and quantity. They used single quality classification criterion or combining dimension classification criterion in classification activity. Second, pre-service elementary teachers have classification strategy that apply each various classification criterion, and also classification strategy are different according to subject, but discussed that "anchor" and "priming effect" are important for effective classification. Result of this study is expected to contribute classification research and classification teaching program development.

Journal of Korean Elementary Science Education, volume 27, issue 1, 2008, Pages 23~30
The purpose of this study was to provide the basic data for development of consulting model in elementary science class. For this, some questions on the teachers' perception for science instruction were surveyed to teachers : 13-item-questionnaires were given to 233 teachers in elementary school. The results of this study were as follows: Most of teachers were little understanding and experience of the science instruction consulting. They sensed that their science instruction were difficult, especially experimental activity in science class. They desired consulting mightly in their teaching methods for experimental activity. And it was found that most of them had a mind of consulting participation. Thus it is necessary to inform them the need of the instructional consulting. And in case of the development for the consulting manual, it should be consider the above results.

The purpose of this research is to investigate the preconceptions of the Earth for 3rd grade students in elementary school. For this study, We interviewed with 30 students and children responded the questions with drawing the pictures. Through the study, We could find as followings. First, they thought that the shape of Earth is sphere only except one who had double conceptions of sphere and flat. Second, the color of the earth seems to be blue because of sea, but mostly answered, it seems to be green more than brown because of continent. Third, the conceptions of the gravity showed us 43% which is the kinds of scientific conceptions for the Earth.
Exploratory Developing Instruments for and Assessing Awareness of Science Teaching through Analogy among Pre- and In-service Elementary Teachers

Journal of Korean Elementary Science Education, volume 27, issue 1, 2008, Pages 42~48
The purpose of this study was to develop an instrument for assessing teachers' awareness of science teaching through analogy (ASTA) and to establish its validity and reliability. Based on the literatures on science teaching with analogies, we constructed 23 survey items. Face validity of the items was established using three science education experts. Through exploratory factor analysis with responses of 35 pre- and 26 inservice elementary school teachers, the instruments were constructed on four subcategories: awareness of analogies in science, use of analogy in teaching and learning, self-efficacy in science knowledge, and knowledge of analogy. The data collected from pre- and in-service elementary teachers demonstrated that overall the teachers' awareness of analogy in science was neutral, which indicated they did not have clear standpoints of science teaching through analogy. Further examination demonstrated that there was no significant difference between pre- and in-service teachers and between two genders. Moreover, there was no significant difference among teachers who preferred either didactic or discovery teaching approaches. We conclude that ASTA test would contribute assessment of teachers' awareness of analogy in science teaching while further examination of the instrument will warrant for its broader use.
Development of the Quotient Equation of the Hypothesis Evaluating Ability by Analysis of the Pre-service Elementary School Teachers' Knowledges for Evaluating Hypothesis on a Woodpecker Task
Lee, Jun-Ki ; Lee, Il-Sun ; Kwon, Yong-Ju ;
Journal of Korean Elementary Science Education, volume 27, issue 1, 2008, Pages 49~59
The purpose of this study was to invent a quotient equation which could quantitatively evaluate individual's hypothesis evaluating ability. The equation was induced by the analysis of the classification types about hypothesis evaluation knowledges generated by 15 pre-service elementary school teachers and the construction of the quotient equation on hypothesis evaluating ability. The hypothesis evaluation task administered to subjects was dealt with the woodpecker behavior. The task was initiated by generating hypothesis on the following question: 'Why don't woodpecker have brain damage after pecking wood?' Subjects then were asked to design and perform experiments for testing hypothesis. Finally they were asked to evaluate their own hypothesis based on the collected, analyzed and interpreted data. The knowledges generated from their evaluating hypothesis were analyzed by 4 major categories (richness, type, level and accuracy). Then, a general equation which could quantitatively and systematically evaluate individual's hypothesis evaluating ability was invented by an inductive process. After combining all the categories the following quotient equation was proposed; '
'. According to this results, woodpecker task and hypothesis evaluating ability quotient equation (VQ) which invented in this study could be applied to a practical use of measuring students' ability of scientific hypothesis evaluation.

The purpose of this study was to examine the effects of a brain-based science teaching and learning model on the science related attitudes, scientific inquiry skills and science knowledge of the 2nd graders in Intelligent Life course. For this study, 117 elementary students from four classes of the 2nd grade in Seoul were selected. In the comparison group, traditional instruction was implemented and in the experimental group, instruction according to brain-based science teaching and learning model was implemented for four weeks. The results of this study were as follows : There were little differences between the comparison and experimental groups in terms of the science related attitudes except for the sub-domains of interest and curiosity. And brain-based science teaching and learning model programs improved a few scientific inquiry skills, especially observation and classification. In addition, the experimental groups showed a positive effect on science knowledge. In conclusion, brain-based science teaching and learning model programs were more effective in improvement of the science related attitudes, scientific inquiry skills and science knowledge of elementary students.
A Analysis on Consistency of Learning Objectives of Units and Instructional Units in Elementary School Biology Teaching Guide-Books
Kim, Jung-Min ;
Journal of Korean Elementary Science Education, volume 27, issue 1, 2008, Pages 75~82
The purpose of this study was to examine the consistency and balance of learning objectives of units and instructional units according to grades and educational domains. Educational domains were cognitive(scientific knowledge), scientific inquiry(inquiry process skills), affective(scientific attitude), and science-technology-society(STS). Learning objectives of life field of the 7th elementary science curricular teaching guidebooks were analysed. Scientific inquiry process skill objectives(43.5%) were most dominant in units, but cognitive objectives(53.9%) were most dominant in instructional units. STS objectives were most recessive in both units and instructional units. Especially, objectives of units and instructional units were shown no consistency by grade. The results of this study suggested that the textbooks and teaching guidebooks should be developed consistently by considering learning activities and contents on the basis of background and properties of science curriculum.

In this study, we developed elementary science education modules for facilitating students' understanding of the connected nature of Science-Technology-Society. For these modules, we particularly used news articles to make connections among science, technology, and society. We set up the development criteria as followings: connecting science-technology-society, aligning with national science curriculum, respecting students' interest, and appropriating the difficulty levels in terms and concepts. We also studied 4th grade students' perception of using these modules in science lessons. Most students perceived that using the modules in their science classes helped them link science-technology-society intimately and enhance their interest and motivation, as well as their self-esteem for studying science.
