This study have an intention of identifying multiple intelligence aptitude, career tendency and career maturity of verbal writing gifted students. 60 verbal writing gifted students who have achieved success in the writing contest were collected for this study. The data was selected through survey MI instruments from the students. The results are summarized as follow. First, verbal writing gifted students' MI profiles were revealed that linguistic intelligence, musical intelligence were strong, and logicalmathematical intelligence was weak. Second, many verbal writing gifted students showed strong musical career aptitude and strong linguistic career aptitude but few writing gifted students showed strong logical-mathematical aptitude. It was revealed that logical-mathematical interest had significant relationship with logical-mathematical achievement in the p-value<.01. Third, there were many linguistic career tendency students & interpersonal career tendency students. But there was no naturalist career tendency student. Musical career tendency, naturalist career tendency showed big differences between strong career aptitude and career tendency. Fourth, career maturity of verbal writing gifted student was very high. The finding can be explained that most of them have characteristics of early career maturity. Parents, teachers, specialists have to provide career information matching strong aptitude and aptitude improving education matching career tendency to the verbal writing gifted students to choose their career successfully.

The purpose of this study was to examine the effects of using process-based writing poems in the elementary mathematics classrooms. For this study, we chose 128 elementary school students to examine their mathematical achievements and attitude towards mathematics when using process-centered writing poems in the elementary mathematics classrooms. Process-based mathematics and writing programs developed mainly on the geometry units were composed of four levels, idea generation, idea selection, use and idea organization grouped into similar sections in order to separate into two sections. The results of the practice of this study's problem can be summarized as follows. First, the process-based mathematics and writing activity of geometry had a positive impact on academic achievement in mathematics. Although there was not a significant difference in the fourth and fifth grades, significant differences in the fifth and sixth grade were found. Second, in regards to attitudes in mathematics, process-based mathematics and writing activities had a positive impact. In particular, the improvement of mathematical attitudes was evident in all grades. It confirmed the effective facilitation of interest and enjoyment towards learning mathematics by 4th, 5th and 6th graders who had undertaken these mathematics classes.

Achievement profile by attribute in Korean students' mathematics was analyzed by applying cognitive diagnostic model, which is the newest measurement theory, to 2011 NAEA(National Assessment of Educational Assessment) results. The results are as follows. As the level of school is higher from 6th grade, 9th grade to 11th grade, the percentage of students mastering cognitive attribute 9(expressions using picture, table, graph, formula, symbol, writing, etc) drastically declined from 78%, 35% to 26%. It is necessary to have learning strategies to reinforce their abilities of expressing table, graph, etc. that higher graders in mathematics are more vulnerable to. Next, the property of mastering cognitive attributes according to gender, multi-cultural family was analyzed. In terms of mathematics, the percentage of girls mastering most of the attribute generally is higher than that of boys from 6th grade to 9th grade, however, boys show higher mastery in almost attributes than girls in the 11th grade. Compared to boys, the part where girls have the most trouble is attribute 9 in mathematics(expressions using picture, table, graph, formula, symbol, writing, etc). As international marriage, influx of foreign workers, etc. increase, the number of students from Korea's multi-cultural families is expected to be higher, therefore, identifying the characteristics of their educational achievement is significant in reinforcing Korea's basic achievement. In mathematics, gap of mastery level of attributes between multi-cultural group and ordinary group is more severe in higher grade and the type of multi-cultural group that needs supports for improving achievement most urgently changed in 6th grade, 9th grade and 11th grade respectively. In the 6th and 11th grade, migrant students from North Korea show the lowest level of mastering attributes, however, in the 9th grade, the mastery rate of immigrant students is lowest. Therefore, there is an implication that supporting plans for improving achievement of students from multi-cultural family should establish other strategies based on the characteristics of school level.

The purpose of this study is to find the research trends relating to flipped learning through keyword network analysis. For investigating this topic, final 100 papers (removed due to overlap in all 205 papers) were selected as subjects from the result of research databases such as RISS, DBPIA, and KISS. After keyword extraction, coding, and data cleaning, we made a 2-mode network with final 202 keywords. In order to find out the research trends, frequency analysis, social network structural property analysis based on co-keyword network modeling, and social network centrality analysis were used. Followings were the results of the research: (a) Achievement, writing, blended learning, teaching and learning model, learner centered education, cooperative leaning, and learning motivation, and self-regulated learning were found to be the most common keywords except flipped learning. (b) Density was .088, and geodesic distance was 3.150 based on keyword network type 2. (c) Teaching and learning model, blended learning, and satisfaction were centrally located and closed related to other keywords. Satisfaction, teaching and learning model blended learning, motivation, writing, communication, and achievement were playing an intermediary role among other keywords.

It has been recently emphasized that comprehensive understanding of students' cognitive activities in the process of writing as well as final product is needed in order to develop an effective strategy for science writing. In this study, we investigated the characteristics of writing process in the situation that students wrote a composition in solving the application problem on a science topic. Seven eighth graders selected in the consideration of their science achievement and communication skills were asked to write a composition using think-aloud method. They were also interviewed after their writing work. The analyses of the results indicated that students' writing processes consisted of six distinctive components: generating, organizing, setting, translating, evaluating, and revising. It was also found that the patterns of process components for each student were different in terms of the frequency and the sequence. The patterns of process components were categorized into four types: systematic, tacit planning, trial and error, and random strategies. Educational implications were also discussed.

In this study, the effects of writing a weekly report on the students' self-directed learning, the attitudes toward science, and the academic achievements were examined. Two hundred and three students, second graders of a high school participated. Experimental group performed writing a weekly report, while the comparative group performed regular science lessons. The results of this study are as follows: First, MSLQ test showed that there was statistically significant difference in the self-directed learning skills(p<.05). For sub-factors of motivation region, such as internal goals, extrinsic goals, learning beliefs, task value, and self-efficacy and for sub-factors of learning strategy region, such as meta-cognition, peer learning, time management, critical thinking, and demonstrations showed statistically significant results. Second, TOSRA test showed that there was no statistically significant difference in the attitudes toward science (p>.05). However, for sub-factors, such as scientific inquiry and joy to science class showed statistically significant results. Third, there was no statistically significant difference in the academic achievement in Chemistry I class (p>.05). However, top and low achievement level showed statistically significant results.

Background: Humidifier disinfectant exposure is an ongoing issue, and there is still considerable related controversy. Various approaches are needed to secure scientific evidence on the extent of the victims' damages and for the determination of appropriate compensation. Objectives: The purpose of this study was to assess the association between humidifier disinfectant (HD) use and academic achievement in Korean children. Methods: This study used data from the 8th Panel Study on Korean Children in 2015. For the final study, 1,598 cases were used. T-tests and multiple linear regression analyses were conducted to determine whether the use of humidifier disinfectant is a factor that affects academic ability. Results: Children in groups using humidifier disinfectant showed statistically significantly lower scores in all areas of language, including reading, speaking and writing, and statistically lower scores in all areas of mathematics, including counting, addition and subtraction. In the multiple regression analysis results, which control for the effects of various demographic/social variables, the use of humidifier disinfectants showed statistically significant beta coefficients (β: -0.357, p<0.001), negatively affecting children's language ability. As for the 'math' variable, which was created by combining counting, addition, and subtraction scores, the use of humidifier disinfectants as independent variables also showed statistically significant beta coefficients (β: -0.200, p<0.001), negatively affecting children's math ability. Conclusions: The results of the study showed that depending on whether or not humidifier disinfectants were used, there are differences in children's language abilities, such as reading, speaking, and writing, as well as in their mathematical abilities, such as counting, adding, and subtracting numbers. These findings are thought to serve as a scientific basis for extending the perspective from health effects to more diverse areas of demographic and social impact related to humidifier disinfectant damage and compensation.

Within the field of mathematics education there is an active movement which attempts to apply more beneficial learning activities, like mathematical writing activities, for the students. In this context, the current study attempts to identify elementary school students' cognitive and affective aspects as they participate in a novel writing activity, the 'mathematical fairy tale.' Some positive outcomes from the mathematical fairy tale writing activities were as follows: First, from these mathematical writing activities, students began to reconstruct and adapt the mathematical contents they've learned through their reflective thinking. Second, while the mathematical fairy tale writing activities were going on, the communication of mathematics was greatly animated between the students, and they could get the restudying chance about they've learned. Third, from these mathematical writing activities, many of students became discover the practical using case of the mathematical contents they've learned and they perceived the necessity of the mathematics learning. Forth, from these mathematical writing activities, most of students felt the delights of the mathematics learning and the achievement, so they indicated that their attitude for the mathematics course was changed positively. Lastly, students began to concentrate on their mathematics learning through participation in mathematical fairy tale writing activities of their own accord.

The purpose of this study is to analyze the science reasoning differences of elementary school students' science writing. For this purpose, science writing activities and analysis frameworks were developed. Science writing data were collected and analyzed. Third to sixth grade elementary students were selected from a middle high level elementary school in terms of a national achievement test in Seoul. A total of 320 writing materials were analyzed. The results of the analysis were as follows. Science writings show science reasoning at 52 % for $3^{rd}$ grade, 68% for $4^{th}$ grade, 85% for $5^{th}$ grade, and 89% for $6^{th}$ grade. Three types of scientific reasoning such as inductive reasoning, deductive reasoning, and abductive reasoning appeared in science writing of the third to sixth graders. The abductive reasoning appeared very low in comparing with inductive and deductive reasoning. Level three appeared the most frequently in the science writing of the elementary students. The levels of inductive and deductive reasoning in science writing increased according to increasing grade and showed statistical differences between grades. But the levels of abductive reasoning did not show an increasing aspect according to increasing grade and also did not show statistical differences between grades. The levels of inductive reasoning and deductive reasoning of the 3rd grade was very low in comparing with the other grades.
