        본고는 초등학교 한자교육의 중심을 어휘 교육으로 파악하고 초등학교 어휘 교육 과정에 필요한 字數와 字種을 제안하는 것을 중심 목표로 삼는다. 먼저 선행 연구의 방법・의의 및 한계를 종합하고 이 바탕 위에 김한샘(2009)과 ㈜낱말 어휘 정보 처리 연구소의 데이터 등을 추가적으로 활용하여 ‘초등학교용 교육용 한자’의 선정안을 제시하였다. 구체 논의 과정에서는 초등학교 교과서라는 말뭉치, 등급별 어휘라는 어휘 평정, 조어력, 전문가의 판단 등을 고려해 초등학교 한자교육에 필요한 적정 한자 수 및 한자 선정에 대한 논의를 펼쳤다. 이 중 ‘초등학교 교과서’라는 말뭉치는 그동안 단순 빈도의 측면에서만 이용되었던 것이고, 등급별 어휘와 조어력은 초등학교 교육용 적정 한자 수 선정 시 학계에 처음으로 고려된 것이다. 본고의 논의가 초등학교 교육 현장에서 신뢰하고 활용할 수 있는 ‘초등학교용 교육용 한자’의 선 정에 일정한 보탬이 되기를 바란다.

        This article examined the current state of Chinese education in Korean elementary schools. First of all, we surveyed Chinese education in elementary schools by dividing the types of Chinese curriculum into two categories: the regular and after-school courses. This study also analyzed the current situation of Chinese education by surveying Chinese teachers of the elementary schools in Seoul and collecting qualitative data of the curriculum time, objectives, and quantity of the Chinese education, class types, and the ratio of native Chinese speaking teachers. Overall, the results showed that the elementary students in Seoul really want to learn Chinese, but the educational environment lacks sufficient capacity and quality needed to meet the student demands. A lack of resources is demonstrated by a lack of class time and multimedia materials. The typical teaching method suffers from an absence of native Chinese speaking teachers. The frustration that comes with insufficient resources eventually leads students to lose interest in studying Chinese as their satisfaction levels become low. This lack of dedicated resources tends to discourage future Chinese language study.

        This study explores the morphological awareness of different graders with different vocabulary levels. A total of 275 elementary students (148 5th graders and 127 6th graders) across small, midium and large cities are selected to test their morphological awareness. First, they were divided into 30%, 40% and 30% of students according to their vocabulary levels. Second, they were tested on the recognition tests, the production tests and the distributional tests of English derivational morphemes divided by the prefixes and the suffixes appeared in the English textbooks. The results are: The recognition and production tests show significant differences for both vocabulary levels and different English levels across different grades. However, the distributional test shows no clear difference like the other two tests. Based on the results, the study draws the conclusion that morphological awareness is developing in the order of recognition, production and distribution of morphologized words in sentences. In other words, recognition of forms precedes the production of forms, and the production is followed by the functional awareness of morphologized words.

        As the whole society grows insensible to its own safety, we keep having continuous big fires such as "Deagu Subway Arson Attack" and "The fire at a football training camp in Cheonan Elementary School." However, we fail to have at least a guidbook which contains minimal information regarding how to prevent big fires or arson attacks, moreover there isn't any educational system that allows the public to have a good habit for their safety. As for developed countries right after industrialization, the education on fire prevention and safety became mandatory for all schools and became one of their required school curriculum. If this becomes the case in Korea, Korea will be able to reduce the potential casualties in case of big fires and emergencies. Therefore, in this research, we would like to establish some appropriate measures and standards for fire prevention and safety based upon the current and immature situations in Korea.

        This study aimed to examine English oral reading fluency of 5th and 6th grade students. Twenty three 5th graders and 22 6th graders at an elementary school in Daejeon participated in the study. Four texts were prepared: a 5th grade equivalent dialog text, a 5th grade equivalent narrative text, a 6th grade equivalent dialog text, and a 6th grade equivalent narrative text. The students were asked to read them aloud at the end of the first semester and the second semester. Comprehension check-up questions were given immediately after they read the texts. Their reading rate was measured in the number of words they read correctly per minute (WCPM). At the end of the school year, the 5th graders read their grade level dialog text at 103 WCPM on average, and the narrative text at 97 WCPM on average. The 6th graders read the dialog text 111 WCPM on average, and the narrative text at 99 WPCM on average. The correlations between reading rates and comprehension were moderate; .60 at the first administration and .58 at the second administration.

        The present study sought to examine the continuity of the English textbooks of the elementary school 6th grade and the middle school 1st grade by analyzing the readability and vocabulary difficulty of their reading passages. It investigated the continuity between textbooks of the two grades and among chapters of each textbook. For the analysis, Flesch-Kincaid Grade Level Index was used to measure the readability of reading passages, whereas vocabulary difficulty was measured in terms of TTR (type-token ratio) and frequency by using VocabProfile. The results showed that the readability of middle school textbooks was one point higher than that of elementary school textbooks. Given that the readability index is based on the American school system, the increase in readability index between grades can be seen as large gap. In terms of vocabulary difficulty, the total amount of vocabulary in the middle school textbooks was three times as much as that of the elementary school textbooks. Second, readability index fluctuated across the chapters of each textbook, while the TTR was found to be higher in the former chapters than in the latter chapters in elementary school textbooks. All these could lead to learning difficulties for students. Pedagogical implications are discussed.

        The purpose of this study was to evaluate the effect of dietary education on improving preferences to Korean traditional foods in upper grades schoolchildren. The education group consisted of 184 children (4th=65, 5th=50, 6th=69), while the control group consisted of 135 children (4th=40, 5th=55, 6th=40). Each group was selected from a different school in Changwon. In the education group, 12 lessons were implemented using educational materials based on sensory education. For the evaluation, pre- and post-surveys were performed in each group using self-administered questionnaire surveys. Variables in the questionnaire consisted of self-efficacy, subjective norms, cognitive attitude, food neophobia scale, eating frequency, preference, intake experience, and nutrition knowledge. After education, the knowledge score improved significantly in both groups. However, self-efficacy (p<0.01), subjective norms (p<0.01), cognitive attitude (p<0.001) and food neophobia scale (p<0.001) changed significantly in only the education group. The intake frequency of Korean traditional foods did not significantly increase in either group. However, the preferences and intake experience of the foods, which were offered in class and school meals, changed significant in only the education group. In conclusion, dietary education based on sensory education may be useful for developing a positive eating attitude for Korean traditional foods in children.

Indoor radon densities of elementary schools by season were 86.4 Bq/m3 in winter, 71.2 Bq/m3 in fall, 61.1 Bq/m3 in spring, and 40.5 Bq/ m3 in summer in order. Among flooring materials by construction material, the radon level of concrete was 57.8 Bq/ m3, and cement was 71.5 Bq/m3. For exterior wall materials, it was established that the density of cement, concrete, wood, and soil was 102.9 Bq/m3, 64.4 Bq/m3, 51.0 Bq/m3, and 48.7 Bq/m3, respectively. In addition, for radon densities according to distances between a detector and floors, 150 cm and under was recorded at 99.3 Bq/m3, 151 to 200 cm was recorded at 62.6 Bq/m3, and 201 cm and more was recorded at 59.2 Bq/m3 sequentially. From the results of analyzing correlations between radon concentrations and factors affecting the indoor radon concentrations in elementary schools, it was discovered that the nearer the distances to floors were and the older the construction was(r = 0.300), the higher were indoor radon concentrations. With regard to factors influencing the indoor radon concentrations in elementary schools, derived from multiple regression analysis, it was revealed that distances from floors has the greatest influence(β = 0.354, p < 0.05). And it was determined that the construction year was also a factor contributing to indoor radon levels. This had an explanation power of 27.9%.
