This study is to investigate preconception of elementary school students and Belizean elementary school teachers and to devise experiment to understand a cause of seasonal change. An open-ended questionnaire and interviews were conducted for 91 6th grade students who didn't learn seasonal change and 10 Belizean teachers to find out preconception of seasonal change and they were categorized by using inductive analysis. They thought that the Earth's rotation, the distance between the Sun and the Earth, the Earth's revolution, pollution and climate change cause seasonal change. And it found out that these misconceptions come from difficulty in awareness of space and impreciseness of textbooks and books and so on. The experiment was designed to correct inaccurate preconception and to improve lessons of seasonal change. It is to measure a meridian altitude and a length of daytime and nighttime and to compare them. This experiment can help to understand the cause of seasonal change by measuring natural phenomenons like the meridian altitude and the change of length of daytime by model.

Purpose: Advanced aged pregnancy may be related with health problems so that more aggressive health care is necessary for these women. This study aimed to provide the basic data for developing nursing intervention programs to enhance the health of pregnant women and their new-born babies and by identifying the advanced aged women's need for pregnancy and childbirth. Methods: It is the cross-sectional descriptive study to identify the advanced aged women's need on pregnancy and childbirth. Subjects were pregnant women 35 years or older and postpartum women. Total number of subjects was 95. Measurement tool is self-reporting survey that consisted of 67 items with four-point Likert scale, which was completed during October to November 2014. Results: Average score was 3.44 out of maximum 4 on the care need on pregnancy and childbirth. Average scores according to category were as follows: baby rearing and parental role, 3.55; preconception care, 3.49; delivery care, 3.47; postpartum care 3.42; and prenatal pregnancy, 3.39. The degree of needs on pregnancy and childbirth was different according to delivery experience (t=-2.49, p=.014). Conclusion: Prenatal and postpartum nursing interventions were completed regardless of pregnant women's age until now; however, new nursing intervention programs are necessary to prevent the risk of advanced aged pregnancy, to provide the preconception care, and to increase the infant care and family support.

The purpose of this study was to find out the responses of students confronted with discrepant situation about inertia concept. We had developed two discrepant situation patterns according to conceptual change model(Kwon, 1989). And we examined the students' responses to the discrepant situations of the 3 inertia problems by interview method. In the result of this study. many students in discrepant situation 1 failed to explain the situation Some students gave up their preconception and showed new conception that was different from preconception. But most of their new conceptions were not scientific conception. In discrepant situation 2. the major characteristics of students responses were the assimilation strategies. Many students modified their preconception in some part but didn't change it. After discrepant situation. students' conceptions were changed more diverse conceptions than preconceptions.

Purpose: The aim of this study was to conduct a scoping review of knowledge and information delivery modes related to preconception care (PCC) among adolescent girls and women. Methods: A scoping review was performed on studies selected from five electronic databases (Cochrane Library, PubMed, Science Direct, CINAHL/EBSCO, and ProQuest), published between 2012 and 2022, with predetermined keywords and criteria. We included English-language research articles available in full text and excluded irrelevant articles. Results: This study included eight articles, comprising seven quantitative studies and one qualitative study conducted among adolescent girls and women. Five were from low- and middle-income countries and three were from high-income countries. The synthesized themes generated from the data were PCC knowledge and PCC information delivery modes and effectiveness. In general, adolescent girls and women were found to have basic PCC knowledge, including risk prevention and management and a healthy lifestyle, although more extensive knowledge was found in higher-income countries than in lower-income countries. The delivery modes of PCC information have grown from individual face-to-face conventional methods, which are used predominantly in lower-income countries, to more effective digital mass media. Conclusion: Globally, many women still have insufficient knowledge regarding PCC, as not all of them receive access to PCC information and support. PCC promotion efforts should be initiated earlier by involving a wider group of reproductive-age women and combining individual, in-group, face-to-face, and electronic delivery modes.

This study investigates how the lunar phases drawing module-applied instruction affects high school students' conceptual changes of the lunar phases. 46 juniors in a high school were given the module instruction on drawing the lunar phases, and then interviews were conducted to verify conceptual changes in subjects' recognition structures. The types of students' misconceptions of the lunar phases change before the instruction were as follows. Type S is that the Earth's shadow covers the moon. Type SR is that one has both misconception of Type S and a scientific concept at the same time according to the positional relationships. The scientific concept means that an observer sees a moon's part which reflects sunlight. Type SB is that the Earth's shadow covers the moon or the moon can be seen or not by the background's brightness according to the positional relationships. The last Type SRB includes all three above-mentioned types, and it explains the lunar phases at each position. As a result of the module-based instruction, 26 out of 36 subjects built up the scientific concept and 10 students did not. 7 out of the 11 Type S and 3 out of the 17 Type SR students did not, either. Especially, type S students did not change their preconception that the phases of moon change were done by the earth's shadow. Here, their preconception is too much strong; as they solve problems, their preconception is more beneficial, comparing to the method which it is presented from the module. This fact supports that it is difficult for students to discard preconception.

In this study, elementary school students' responses toward a discrepant event about a float-or-sink problem were investigated through semi-structured interviews. Initial participants were 61 fifth-grade students from two elementary schools. After excluding the students who did not possess the target misconception from the results of a preconception test and who were not willing to participate in an interview, 31 students (14 males and 17 females) were finally interviewed by two teacher-interviewers. During the interviews, students were first provided with a hands-on experiment which was the same as the situation in the preconception test, and then they were asked about believability of the discrepant event, inconsistency between the discrepant event and their existing conceptions, and belief change after experiencing the discrepant event. Interviews were audio- and video-taped, and then were transcribed by two interviewers. After analyzing the interview transcriptions, we found four types of students' responses; rejection, uncertainty, peripheral belief change, and belief change. We also found that belief change response type should be classified into three distinctive subtypes; belief decrease, ad-hoc belief change, and analytical-abductive belief change.

과학사를 살펴보면 아리스토텔레스만큼 엉터리 물리학으로 사람들의 믿음에 절대적인 영향을 준 인물도 드물 것이다. 그는 무거운 물체가 가벼운 물체보다 더 빨리 떨어진다고 주장했는데. 그의 이러한 생각은 거의 2천년 동안 진리처럼 받아들여졌다. 갈릴레이가 사고실험(思考實驗)으로 그의 생각이 틀렸다는 것을 증명하고, 뉴턴이 물리학의 틀을 확고히 세웠지만 오늘날에도 이러한 생각을 가진 사람들은 많다. 이는 아리스토텔레스의 영향력이 오늘날까지 이어지고 있는 것이 아니라 자신의 경험에서 유추한 물리에 대한 잘못된 선개념(preconception)을 가진 사람들이 많기 때문이다. 이러한 엉터리 물리학을 물리 오개념(misconception)이라고 부르는데 이러한 물리 선개념은 쉽게 고쳐지지 않으며, 심지어 과학전공자나 과학책에도 이러한 것들이 종종 발견된다.

In our culture, the term, "be like", is frequently used. There are expressions such as "feminine-looking dress" and "manly style" relating to this term when we describe the styles of clothing. This study addresses the question on which type of garment would be selected under the description of the term, "be-like", in relation to gender. This term reveals the preconception of gender as being feminine or masculine according to the styles and colors of clothes. A group of 362 college students from Seoul and Gyeonggi area was surveyed fur the study The statistical analysis of SPSS 10.0 was applied f3r analyzing the data, and the significant variances were reviewed by the basic statistics, multi-variate and T-test. The results are as follows: First, the details of clothes imply the preconceived idea of gender. As a result, women's blouses and skirts were selected as the most feminine upper and bottom garments. The Y-shirt and T-shirt were selected as the most masculine upper garments. However, in contrast to the . skirts being the most feminine bottom wear, the pants were not significantly recognized as the most masculine ,clothes. Second, the variances of the survey show that the female students are more conscious of the sexual identity expressed in clothes than the male students. Third, the styles of clothes reflect the general understanding of what is considered to be "feminine or not feminine" and "masculine or not masculine" In conclusion, this study has discovered that the certain characteristics of gender are predominantly implicated in the styles length, and color of clothes. Both men and women responded differently in defining their idea of "femininity" and "masculinity". Nevertheless, there still exists strong preconception of what is considered to be feminine or masculine, and it affects the choices people make in selecting clothes.

This study was intended to answer the question, 'What kinds of effects will be aroused by experiential learning for environment based on living area?'. Experiential learning for environment was operated to 17 elementary school students in 4th grade in Kyeong-san city. The results were drawn analyzing the mind map for the changes of environmental consciousness before and after learning, and they are as below. First, it had an effect to change the meaning association of the relationship between 'river and me'. Meaning association was 'river-a thing' before experiential learning, but it was developed as 'river-a thing-me' after learning. This means that students expanded understanding of the world that they were belonging and self-spatialization was promoted. The expansion of meaning association would be a start point and a method to promote their segmentation for each student. Second, students could self-directly modify misconception and preconception after experiential learning. It showed that students could find meanings in the world that they were belonging by experiential learning for environment, and misconception obtained by concept learning without actual situation could be revised through the truth recognition in meanings, and student could see what things displayed. Therefore preconception would be corrected. Of course, everything would not be completed by just one time of experiential learning, and consistent experience learning should be operated. Third, experiential learning promoted the change of sensitivity. Students had shallow sensitivity, which appeared in the relation with things, since having learned only inside of class without a direct observation. However their sensitivity could be increased by experiencing specific things. Fourth, there was the change of classification recognition. Students found properties of things with a direct observation. It raised their ability to classify things, and to understand an individual thing in 'a class'.
