  • This study was to evaluate the suitability of scientific questions as qualification examination for high school graduation by content validity and item response with three examinees and two preliminary examinees. As a result, scientific questions were concentrated on two units of six units of total, and application appeared to be lacking problem area by 8% compared to understanding and application. Examinees and preliminary examinees chose correct answers most by hap or guess, sometimes by experience or common sense, and the least by scientific concept. In addition, they could chose correct answers by hap or guess because there were words that implied the correct answer in questions and answers, or because they could compared and/or analyzed questions and answers. With these results, two proposals were suggested as follows; (1) scientific questions of qualification examination for high school graduation should measure basic scientific literacy. (2) specific criteria for science literacy in qualification examination for high school graduation should be set.

  • Scientific reasoning is one of the main concerns in current science education. This study have tried to answer on the question whether Korean science education has the potential to help improve of students' ability to think scientifically. Therefore, the present study investigated the relationship between reasoning patterns evident in science textbook and science examination items, and students' scientific reasoning skills across grades in Korea. 1975 subjects (1022 females and 953 males) were administered in the Lawson's Test of Scientific Reasoning skills. Forty seven science textbooks and 240 assessment instrument were analyzed by several scientific reasoning keys. Scientific reasoning patterns were adopted from Lawson's classification which characterized the patterns as the empirical-inductive and the hypothetical-deductive. This study found that reasoning patterns evident in textbook analyses and assessment instrumental items do not evidentce the potential to stimulate the development of students' reasoning skill. In order to improve the students' abilities to think and achieve, higher levels of reasoning must be included in the science textbook and examination. Further, some of scientific reasoning processes, such as generating hypotheses, designing experiments, and logical prediction, were not found in science textbooks and test items in Korean secondary schools. This study also discussed the educational implication of these results and further studies about to develop student's reasoning ability.

  • This study examines how the project approach utilizing beans as the subject matter influences young children's scientific research capabilities and scientific attitudes. This examination ultimately aims at developing effective teaching methods and programs that can promote children's scientific research capabilities and scientific attitudes. Thirty six children at H kindergarten in Gunsan, Jeollabuk-do were selected as subjects of this study. The children aged five were divided into an experiment group and a comparison group, with eighteen for each group. Before the experiment, a pre-test was conducted on the children's scientific research capabilities and scientific attitudes. The pre-test results were subject to a t test to identify whether there were differences between the two groups in age as well as the levels of scientific research capabilities and attitudes. A post-test was also conducted to determine the differences between the two groups in these categories. These results have led to the conclusion that the project approach utilizing beans as the subject matter has a positive impact on improving young children's scientific research capabilities and scientific attitudes.

  • Key concepts in South Korean nuclear safety regulation are safety and risk. Nuclear regulation in South Korea has required reactor designs and safeguards that reduce the risk of a major accident to less than one in a million reactor-years-a risk supposedly low enough to be acceptable. To date, in South Korean nuclear safety regulation has involved the establishment of many technical standards to enable administration enforcement. In scientific lawsuits in which the legal issue is the validity of specialized technical standards that are used for judge whether a particular nuclear power plant is to be licensed, the concept of uncertainty law is often raised with regard to what extent the examination and judgment by the judicial power affects a discretion made by the administrative office. In other words, the safety standards for nuclear power plants has been adapted as a form of the scientific technical standards widely under the idea of uncertainty law. Thus, the improvement of nuclear safety regulation in South Korea seems to depend on the rational lawmaking and a reasonable, judicial examination of the scientific standards on nuclear safety.

  • The purpose of this study is to compare and analyze how many species of trees presented with scientific names are on the written test for engineer landscape architecture, as their usage has increased in the landscape industry in recent years. The following is the result of comparing and analyzing the species of trees which are frequently used in landscape, planting construction, and the scientific name questions presented in the previous 6 years by year on the written test for engineer landscape architecture. First, the results of analyzing the examination question frequency by year in the landscape planting subject showed a gradually declining trend from 2014 after peaking at 56.6% in 2013. Second, 163 species of trees using scientific names were presented in questions on the written test for engineer landscape architecture over the previous 6 years and these included Betula platyphylla, Sophora japonica, Cercis chinensis, Taxus cuspidata. The number of species of trees used in landscape construction during the same period was 169 including Pinus densiflora, Chionanthus retusus, Cornus officinalis, Syringa dilatata. The result of interviews with landscape planting construction officials showed that when choosing the species of trees, they emphasize ecological characteristics, such as the ratio of trees to shrubs, flowers and autumn leaf characteristics, and also consider the morphological characteristics, landscape characteristics, economic feasibility, and the supply and demand situation. Third, it was found that 70 (42.9%) out of 163 species of trees presented with scientific names on the examination were not used in landscape planting construction and 76 (44.9%) out of 169 species were not used as material for questions. As for the scientific name questions, deciduous trees and evergreen shrubs accounted for the more questions, Evergreen and deciduous tree and shrubs were most common in landscape planting construction as well.

  • The essential point to be considered when restoring lacquered ware is to know its materials and properties, and prior studios from the conservational and scientific examination is the way to achieve it. Recently, to get a close examination of its materials and methods involved in lacquered ware making, cross section microscope studies are being applied. Cross section microscope studies shows that lacquering process has been simplified and that bone and earth substances have been added to the materials, a method also traced from the lacquered wooden coffin excavated from the 'Nak Rang Tomb' and by the lacquered wares of the 'Kyongjoo An Ap' areas. The significance of this Chosun Dynasty lacquered wares's inlaid with mother-of pearl restoration can be found in that we have been able to harmonize the very traditional and the very modern scientific method of our time and that we were able to launch a step forward from using only the synthetics to open up a new range of natural materials such as lacquers, bone and earth substances, oxhide-glue and nacres and of referring to the traditional methods.

  • The purpose of this study was to develop the instrument for scientific attitudes in school, home and social situations and select the important elements of scientific attitudes. Looking into the elements of scientific attitudes in national and international research, the important elements of scientific attitudes students should have were selected as follows: Openness, objectivity, continuousness, criticalness, prudence, volunteerism, honesty, preparedness, collaboration, and curiosity. To develop the valid instrument of scientific attitudes, we moved forward with the step of making preliminary questions, the judgment step, and the validation examination step. Based on the elements of scientific attitudes and school, family, and social situations, the instrument of the scientific attitudes was developed. We discovered that Middle school students' scientific attitudes, according to their grade levels, appear to be significantly lower than those in the 7th graders and 9th graders. The scientific attitudes in school, home and social situation appeared high in order of society, home, and school. It appeared that there were no differences by gender.
