  • This study analyzed the 6th grade elementary science textbook 'Science stories' reading process of students by utilizing eye movement tracking techniques. Participants read 3 articles in the new experimental science textbooks and solved 9 problems about each article. By understanding and academic achievement results, participants were divided into high-groups, middle-groups, and low-groups. The results of eye movement characteristics of the high-groups and low-groups had the following differences. Number of fixations and number of regressions were higher in high-groups. Average fixation duration and average regressive fixation duration were longer in low-groups. Fixation time for the key sentence of the article was longer in high-groups. Analysis of a scan path and post-interview, high-groups had frequent regression between sentences and they knew where the core of the article is and paid much attention there. In contrast low-groups are sequentially read most articles and some of them had a leap of abnormal range. Problem-solving approach is also different between groups. In conclusion reading style is associated with the science stories comprehension and students who had more regressions, much core search process, effective attention distribution, high concentration showed better understanding results. Also words or sentences used in textbooks are associated with science stories comprehension.

  • Purpose : We need to reconsider booster vaccination schedule of Japanese encephalitis vaccination. To do that we evaluate the long-term immunogenicity and the incidence of adverse events with inactivated mouse brain derived Nakayama Japanese encephalitis vaccine. Methods : We tested neutalizing antibody for 311 elementary school students by plaque reduction neutralizing test(PRNT) at USAMC-AFRIMS(United States Armed Forces Research Institute of Medical Science/Department of Virology). We evaluated vaccine related adverse events by spontaneous reporting prospectively among 15,487 vaccinees who were vaccinated at public health center and 2,277 elementary school students who were immunized previously by a questionnaire and school health record. Results : According to the time interval from the last booster injection of 311 children, PRNT antibody titers gradually decreased as the interval increased; 239 mIU/mL, 188 mIU/mL, 134 mIU/mL, 49 mIU/mL each at 6, 18, 30, 42 months after the last booster injection. The seropositivity rates were 98%, 99%, 95.6%, 71.4% each at 6, 18, 30, 42 months after the last booster injection. There were 21(0.13%) cases with systemic reactions among 15,487 vaccinees who had visited the hospital by prospective passive reporting system at public health center. According to the questionnaires and school health records in elementary school students, local induration and pain were 17.4% and 14.8%, respectively. Systemic reactions including fever, vomiting, rash were reported in few cases. Conclusion : Biannual booster vaccination that has been recommended so far should not be necessary. Surveillance for adverse events with inactivated mouse brain derived Nakayama vaccine should be strengthened to better assess the number of cases and reactions associated with immunization.

  • This dissertation is aimed to investigate the reason why a contextualization is needed to help the meaningful teaching-learning concerning multiplications and divisions of fractions, the way to make the contextualization possible, and the methods which enable us to use it effectively. For this reason, this study intends to examine the differences of situations multiplying or dividing of fractions comparing to that of natural numbers, to recognize the changes in units by contextualization of multiplication of fractions, the context is set which helps to understand the role of operator that is a multiplier. As for the contextualization of division of fractions, the measurement division would have the left quantity if the quotient is discrete quantity, while the quotient of the measurement division should be presented as fractions if it is continuous quantity. The context of partitive division is connected with partitive division of natural number and 3 effective learning steps of formalization from division of natural number to division of fraction are presented. This research is expected to help teachers and students to acquire meaningful algorithm in the process of teaching and learning.

  • The purpose of this study is to prevent and review counter-action for the sexual harassment in campus by revealing current state of sexual harassment in campus relatively weak in sexual discrimination with regard to sexual harassment emerged as social problem serious in our nation. The targets of study were students and assistants in three schools located at $Kwangju\cdot{Chonnam}$ area, a questionnaire made by pre-researcher was applied to student vs. assistant with regard to sexual consciousness and recognition, and current state of sexual harassment, with analysis of material processed through statistical analysis using SPSSWIN 10.0 for verification of $$\chi$^2$ for identification of difference vs. family and student vs. assistant. The result of this research with regard to sexual harassment is under following: Firstly, the recognition of concept of sexual harassment was proved to be aware of be more than half a responders above average, lack of recognition showed significant number requiring establishment of concept of sexual harassment, the responders stated that they could do it alone should be treated in the counseling room in school. Secondly, 28.7% of students and assistants answered that they have suffered from sexual harassment now and. before, even a great number of males have experienced such sexual harassment. In case of female assistants, more than half of them suffered from sexual harassment suggesting us significant level of sexual harassment to female assistants. A depth of sexual harassment to assistants should be investigated in a further way by preparing for and establishing concrete preventive actions and researches, mostly suffered by males; In this respect, a preventive training of sexual harassment should be deemed to be provided to males. Thirdly, as a result of investigation of sex education and preventive action against sexual harassment in college, most of elementary, junior, junior high school hardly provide no or inefficient sexual harassment, and they responded that the campus needs its education. As a way to educate campus with sexual harassment efficiently, a special lecture or regular class might be designed for systematic education or sexual harassment through schools counseling room might be effective emphasizing upon role of the room according to opinions of responders. The college is required to install such offices or centers as can exclusively manage and take charge of sex education program operation, legal system of anti-sexual harassment, or personnel arrangement for such activities in school by reflecting such result into school for appropriate and efficient education of or counseling to sex.

  • This study analyzed the kinds and frequencies of descriptors in 154 articles in ERIC data base on the 4th day of January in 2010. The titles of the articles includes the words, 'scientific literacy'. As each descriptor is constituted of two words and over, in this study the first word in the descriptor was defined as 'restrictive word' and the rest word(s) as 'target word(s)'. The results are as follows. First, the descriptors which show high frequencies of target words are the traditionally important themes of scientific literacy education. Target words which show relatively high frequency are 'education', 'literacy', 'instruction' and 'countries'. Low frequency word is 'curriculum', which has various restrictive words and represents wide differentiation. Second, among the descriptors which show low frequencies of target words, relatively high frequency descriptors are '(and)society', 'change', 'secondary education', 'concepts', and 'biology', which have been given more attention in scientific literacy research than the rest descriptors. Third, the number of the descriptors that shows largely distributed pattern A, which happens over 15 years continuously, is over the half of all analyzed descriptors, which shows that they have been the major objectives in researches about scientific literacy. Most descriptors of pattern A shows normal distribution of frequency or the trends of increasing frequency as the time is nearer. Fourth, The descriptors are divided into four groups according to the time span. Each research trends are as follows. In later 80s, the research which emphasizes the importance of the sociality and technology in all level school science curriculum. In later 90s the research for educational change of inquiry-centered science curriculum which considers technological literacy in social contexts. In earlier 2000s the research that scientists and science teachers develop science curricula mostly related to scientific principles and thinking in chemistry and biology especially. In later 2000s case studies which relates teaching methods and science process activities to students' attitudes, scientific concepts and curricula.

  • Paper & pencil test provides limited informations about student. So many web-based computerized test systems are developed and tried. But These systems have drawbacks that cannot visit previous or next problems freely. So These systems cannot get deep informations such as elapsed time of each problem, history of answer modification, the number of visit time of each problem. These deep informations are very important in educational evaluation area. Therefore we develop educational evaluation system can get these deep informations including basic informations. And then we apply paper & pencil test and our system to 67 students, and execute survey. The reason of survey is to ascertain availabilty of our system.

  • Korea is changing rapidly from a single-raced nation into a multi-national nation caused by the huge number of immigrants mostly from China, and Southeast Asian countries. Therefore, various social problems are expressed ostensibly, one of them is a difficulty suffered by children of the second generation of multi-cultural families who enroll to elementary schools in Korea. This should be solved urgently as it is predicted to be an unavoidable problem in future. Only by understanding and accepting mutual cultural differences will be the solution to various problems caused by multi-cultural society. This study aims to understand the differences of emotion about the spatial images. This study was target to Korean and Malaysian design students to perform vocabulary appraisals on the spatial images in school health rooms which used to perform various functions for education, counseling, treatment, etc. The emotional vocabularies used at the appraisal for emotion are based on IRI image languages, which were extracted by the experts, and frequency was progressed by the SPSS 12.0 application. The collected data will be compared and analyzed to ensure the reliability.

  • Counting occupies a fundamental and important position in mathematical learning due to its relation to number concepts and numeral operations. In particular, counting up to large numbers is an essential learning element in that it is structural counting that includes the understanding of place values as well as the one-to-one correspondence and cardinal principles required by counting when introducing number concepts in the early stages of number learning. This study aims to derive didactical implications by investigating the possibility of and the strategies for counting large numbers that is expected to have no students' experience because it is not composed of current textbook activities. To do this, 89 second-grade elementary school students who learned the three-digit numbers and experienced group-counting and skip-counting as textbook activities were provided with questions asking how many penguins were in a picture where 260 penguins were irregularly arranged and how to count. As a result of analyzing students' responses in terms of the correct answer rate, the strategy used, and their cognitive characteristics, the incorrect answer rate was very high, and the use of decimal principles, group-counting, counting by one, and partial sum strategies were confirmed. Based on these analysis results, several didactical implications were derived, including the need to include counting up to large numbers as textbook activities.

  • With the emergence of new infectious diseases and changes in the educational environment, the health problems of school-age students are increasing. Accordingly, the role of school health teachers is expanding and becoming more important. The study was to examine the effect of calling on school organizational commitment of school health nurses. Samples were a total of 143 school health nurses working in elementary, middle, and high schools, Gyeonggi-do, South Korea who understood the purpose of this study and voluntarily participated in the study. Measures were Calling and Vocation Questionnaire-Korea (CVQ-K) and organization commitmen questionnaire. Data were analyzed using SPSS/WIN 23.0 program. The analyses showed that the prediction model for school organizational commitment of school health nurses was significant (F=16.142, p<.001). The value of the adjusted R2 was 0.307, which corresponds to the explanatory power of 30.7%. The factor that was found to have the most influence on school organizational commitment of school health nurses was purpose/meaning (β=.28, p=.011), followed by number of classes (β=-.20, p=.006). In order to improve the school organizational commitment of school health nurses, the purpose/meaning and the number of classes should be considered.
