It is common to check the validity of an assumed model with the heavy use of diagnostics tools when conducting data analysis with regression techniques; however, outliers and influential data points often distort the regression output in undesired manner. Jang and Anderson-Cook (2013) proposed a graphical method called a firework plot for exploratory analysis that could visualize the trace of the impact of possible outlying and/or influential data points on individual regression coefficients and the overall residual sum of squares(SSE) measure. They developed 3-D plot as well as pair-wise plot for the appropriate measures of interest. In this paper, the approach was extended further to tell the strength of their approach; in addition, a more meaningful interpretation was possible by adding a measure not mentioned in their paper. This approach was applied to the mixture experiment because we felt that a detailed analysis of statistical measure sensitivity is required in a small experiment.

In this paper, we explore the possibility that ladder diagram games can be used for the introduction of the function and composite function. A ladder diagram with at most one rung is a bijection. Thus a ladder diagram with r rungs is the composition of r one-to-one correspondence. In this paper, we use ladder diagrams to give simple proofs of some fundamental facts about one-to-one correspondence. Also, we suggest Story-telling for introduction of function in middle school and high school. The ladder diagram approach to one-to-one correspondence not only grabs our students' attention, but also facilitates their understanding of the concept of functions.

This study aims to analyze and compare the difference of preference to realistic and fantastic expressions presented in the illustrations of children's picture books. The subject of this study is set for 52 seven-year-old kindergarten students, including 26 boys and 26 girls, in Cheonan. Two times of researches on their preferences were made on the basis of data collection through individual interviews and self-regulatory questionnaires. A children's picture book, which best demonstrates both realistic and fantastic expressions, was selected as a research tool for such questionnaire from the ones produced and printed within Korea, which either are listed in the Recommended Book List of Children's Book Research Association or received any international award. The result shows that both boys and girls prefer fantastic expressions to realistic ones. It was also found that girls tend to prefer realistic expressions that the boys do. Nevertheless, there definitely was a limitation in thorough analysis by region or age, as they tended to show different responses when they were provided with a picture book with similar theme and story, but different form of expression.

This paper purposes to provide a new perspective for better development of geography texts. For this purpose, we have applied spatial cognition development theory to children's drawings. We have suggested that children's spatial operation ability has three development stages according to their age: topological space, projective space, euclidean space. This study turns out that Piaget and Inhelder's spatial concept development theory is on the right track. However, we make clear that their division according to the age is not always accurate due to children's individual differences. These findings have educational implications as the following: First, it is dubious that most children can understand pictures, pictorial maps and illustrations in the third grader's textbook. Second, current textbooks require pictorial map understanding and drawing to third grade students and map drawing to fourth grade students. However, according to this study, the placement of these tasks are not fit for children's developmental stage because both tasks correspond to euclidean space operation. Therefore, we should remove them from the textbook for children at the age.

We compared algorithmic problem solving and conceptual understanding of chemistry with three types (algorithmic, pictorial- and wordy-formatted conceptual) of problems. The familiarity, confidence, and preference to the three type of problems were also examined. The chemistry problem solving ability test was administered to 228 students from two top high schools in the province of Gyeonggi who were preparing the chemistry examination among the four optional subjects (biology, chemistry, earth science, physics) for enter university. After administrating the chemistry problem solving ability test, the degree of familiarity to some problems and the degree of confidence of their answers in a Likert scale were asked to the students. Besides, the students were asked to place preference to the type of problems in order. The students scored better on the algorithmic problems than on the conceptual problems (pictorial and wordy problems), and were also most familiar with the algorithmic problems. The students were more confident of their answers on both of types pictorial and algorithmic problems, and preferred pictorial problems rather than both of types algorithmic and wordy problems.

This study examined system, form and contents of including its publication in depth through the analysis on the publication of those days, present condition of extant edition, system and publication, illustrator etc., targeting series which was published in the liberation period. As for series which was published by Eulyoo Publishing and Joseon Children Culture Association(Ahyeop) for building children's life liberation and children culture, 5 books still remain now. For the extinct edition, this study confirmed publication history of books based on the advertisement carried on the newspaper which was published of the time. As a result of analyzing extant edition, this study found that the book was composed equally as a system of cover, beginning, body and the end, and the body was characterized by the composition of 3-cut comic and story as a form of storybook. The size of the book is A5 book size with 32 pages of quantity and was published as a semi-hardcover bound book. As for illustrators, Kim brothers (Yong-hwan, Eui-hwan) who played an active part in the field of art of the time participated.

The purpose of this study is to analyze the statistical literacy in elementary school students when they beginning inference. Picto-graphs provide statistical information and often data-related arguments they certainly qualify as objects for interpretation, for critical evaluation, and for discussion or communication of the conclusions presented. For research, the inference from pictograph task was designed and statistical literacy standards for evaluating the student's level was presented based on prior studies. Evaluating student's statistical literacy is meaningful in that it can check their current level. To know the student's current level can help them achieve a higher level of performance. The outcomes of this research indicate that pictograph can provide a basis for rich tasks displaying not only student's counting skills but also their appreciation of variation and uncertainty in prediction. Raising statistical thinking by students is an important goal in statistical education, and the experience of informal statistical reasoning can help with formal statistical reasoning that will be learned later. Therefore, the task about the inference from a pictograph, discussions on statistical learning of elementary school children are expected to present meaningful implications for statistical education.

Purpose: People with intellectual disabilities are vulnerable to the use of receptive and expressive vocabulary. The purpose of this study was to investigate the effect on the receptive vocabulary and the expressive vocabulary after teaching reading education to adults with intellectual disabilities living in facilities using picture fairy tales. Methods: The subjects of this study were 12 adults with intellectual disabilities under the age of 20 to 40 residing in residential facilities. They were divided into 6 test groups and 6 control groups, and gave a total of 12 sessions of 60 minutes per session, and reading instruction using picture fairy tales. Results: In the test group that conducted reading activities using picture fairy tales, the use of the receptive vocabulary was significantly improved, and the use of the expressive vocabulary was significantly improved. There were no significant results in all of the control groups. Conclusions: This study had the effect of improving the use of receptive vocabulary and expressive vocabulary after teaching reading using picture fairy tales for the disabled. It is estimated that this result will be the basis for research in this field.
