Purpose: This study aimed to develop a four-hour food additive education program for elementary school students to provide them with accurate information on food additives. Methods: A survey was conducted among 133 elementary school students living in Gyeonggi Province to identify the level of food additive awareness. A four-hour food additive education program and educational materials (PPT, activity sheets, and teacher guidelines) were developed based on the results of the food additive awareness survey. The developed educational programs were based on the Theoretical Model of Stages of Behavior Change. An elementary school nutrition teacher conducted a pilot education for 83 elementary school students to evaluate the feasibility of the developed education program. A survey was conducted to evaluate the effectiveness and satisfaction of the pilot education program. Results: The results of the Food Additive Awareness Survey showed that only 42.1% of people were aware of food additives; 46.3% wanted to know more about food additives, and 54.3% required food additive education. Food coloring (44.7%) and artificial sweeteners (18.7%) were the most common food additives of interest. What they wanted to know about food additives was the safety of food additives (36.8%) and the role and function of food additives (20.3%). After the pilot training on food additives, the level of awareness of food additives was improved significantly, and the percentage of participants who recognized the need for food additive education and promotion increased. According to the satisfaction survey of the food additives education, the interest, understanding, real-life application, learning method, and content amount were approximately 90%. Conclusion: The educational program developed through this study will change the negative perceptions of food additives in elementary school students to a positive one. It will do so by helping nutrition educators educate students on this important subject.

In this study, we surveyed the 68 teachers from eight science high school and four science academy for the gifted through questionnaires about research ethics education and ethical research environment in Korea. First, we examined the current state of research ethics education. Half of the responding schools included research ethics education in their curriculum. Although only half of the schools have this in their curriculum, more than half of the total number of teachers surveyed personally taught research ethics in class, and almost 90% of the teachers said they taught the research ethics during students' research activity. However, 63.24% of teachers said that research ethics education was not enough still. Second, we investigated the ethical research environment. In terms of knowledge and experience, the teachers were competent, and they were creating an environment that enabled peers and self-verification. However, research ethics, regulations and verification systems are not well equipped in schools. Since the principals are highly interested in research ethics education, there seems to be enough improvement on the ethical research environment. Finally, teachers said that additional research ethics education, change in student attitude, development and continuous maintenance of the verification system, encouragement to develop ethical environment, and clear guidelines were needed for ethical research of students. The result of this research will be able to provide the following. First, it will help set up a direction for research ethics education at every gifted school. Second, it will provide insights on how schools and teachers can create an ethical research environment for the students of science-gifted students.

The purpose of this research was to investigate how the peer review activity of lab report in the problem-solving experiment effected on the description ability and the quality improvement. The students who were taking the general chemistry experiment course were the subjects for this study. They finished lab reports and received peer review from their peers more than two times. The students who got feedback answered on peer review, revised their reports, and subsequently, completed final reports. The result showed that peer review affected the qualitative improvement of the lab report, specially in the process of 'designing experiment' and 'drawing conclusion and evaluation'. Students could organize their thoughts through writing lab reports. During this process, peer review activities provided the opportunity of self-examination and the way for viewing as objective standpoint. Moreover, the activities established communication fields for exchanging mutual opinions and learning.

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.

The effective teaching of Earth Science in the classroom should be augmented by field studies of rocks and minerals in a competently designed school rock garden(SRG). The displayed specimens must be correctly identified, labeled and esthetically evaluated. SRG is more than a general garden with just landscaping and it should provide students with freedom of conducting independent inquiries. The composition of the selected specimens should be representative of the bedrocks of region as well as of Korea in general. There are 130 schools in Jeonju-city and 35 (26.9%) have established rock gardens. There is a pressing demand for more gardens and number of display samples in school. The existing displays need improvement because some samples are not correctly identified and labeled. In addition, there is a duplication of rock types as well as lack of important rock types. The number and composition of the displayed rocks and minerals should be related to the school curriculum and reflect representative bedrocks of Jeonju-city and region.

The purpose of this study was to analyze experiments for the rules of material change unit in 9th grade science textbooks and develop experiments applying small-scale chemistry (SSC). For this study, experimental methods for the precipitation experiment, water electrolysis experiment, decomposition of hydrogen peroxide experiment presented in the 9 science textbooks were analyzed. Problems and improvements that were needed were extracted by 13 science teachers performing the experiments. Experiments applying SSC were developed based on the improvements needed. Afterwards, 19 pre-service science teachers performed both the developed SSC experiments and the science textbooks' experiments. A questionnaire about merits and demerits of the experiments applying SSC was performed. According to the results of this study, most of the 9th grade science textbooks included the lead iodide precipitation experiment, water electrolysis experiment by Hoffman voltameter, and decomposition of hydrogen peroxide experiment using catalytic manganese dioxide. Improvements were needed on the quantity of reagents, time for performing experiments, and scale of experimental apparatus. Merits of the developed experiments applying SSC which used small amount of reagents were safety, easy waste material disposal, short reaction time, and reproducible experimental results. Demerits of the experiments applying SSC were difficulty in observing, decreased achievement, and lack of skill in handling small-scale apparatus. Therefore, if the experiments developed applying SSC were to be utilized in 9th grade science experiments, it will be possible to use less reagent and be able to teach and carry out reproducible experiments at the same time. Also, the reproducible experiments based on SSC will help students under stand the scientific concepts for the rules of material change unit.

The purpose of this study is to analyze differences in the teaching practices of biology teachers according to their awareness of the importance of evolution. For this purpose, two teachers who experienced study of evolution and recognized its importance, along with two teachers with no experience in evolution education in the comparison group, were included in the sample. To observe teaching practices, two classes each on biological evolution and non-evolution were selected, recorded and transcribed. The content analyzed included the teachers' view on evolution education and teachers' evolution concepts reflected in teaching practice. As a result, the level of understanding of the teachers' evolution concept was unrelated to teachers' awareness of the importance of evolution. Instead, each teacher would not feel the need for religious beliefs or awareness of the importance of evolution to have a negative impact on the awareness of the importance of evolution. Inexperienced teachers tend to reject the retraining opportunities to recognize the importance of evolution. In addition, inexperienced teachers were only superficially aware of the evaluation and improvement of evolution presented in textbooks and curricula. In actual teaching practice analysis, inexperienced teachers' utilizing ratio of the evolution key concept was higher than that of experienced teachers. Only experienced teachers were aware of the misconceptions presented in their execution and described the causes that appear in these misconceptions. Teachers who recognized the importance of evolution were widely using the key concepts of evolution, as well as more practical in preventing the misconceptions related to evolution forms. It indicates that biology teachers who do not realize the importance of evolution in biology education need to experience explicit and practical education programs as well as instructional materials on evolution.
