The necessity of this study was to improve academic achievement and math attitudes through leveled reciprocal peer learning, and the specific purpose was as follows. First, each unit seeks to select learning methods and contents for each level of class for reciprocal peer learning, second, develop activity sites for each level through curriculum analysis, and third, improve academic achievement and math attitudes through classes that apply reciprocal peer learning activities. The study was conducted on 60 second graders of 00 High School in 00 Metropolitan City. Two classes were selected for the midterm exam results for the first semester of the second grade. Class 1 was divided into the experimental group and the other class 1 was divided into the comparative group, and 13 classes were conducted for about 2 months from May 1 to July 4, 2020. The experimental group (30 students) was a class that applied leveled reciprocal peer learning activities, and the comparative group (30 students) was a class that was taught based on traditional textbooks. As a result of this study, first, in this study, it was possible to improve academic achievement and math attitudes by setting learning contents for each unit and applying reciprocal peer learning activities for each level. Second, the experimental group taught by applying leveled reciprocal peer learning activities was effective in academic achievement and math attitudes compared to the comparative group taught based on traditional textbooks to students in the upper, middle, and lower groups. Third, in the class applying leveled reciprocal peer learning activities, low-level students who were neglected in math classes were also interested in the class and actively participated in it, showing improvement.

The purpose of this study is to present the overall landscape of Comparative Education study in teacher training program at universities in Korea. The Comparative Education in Korea is relatively young without a lengthy tail on its name and still on the way of upgrading itself, however various efforts are gathering for the development of Comparative Education. With this understanding, this paper diagnoses the current status of Comparative Education in Korea by analyzing 1) the number of institutions which provide Comparative Education lectures for their teacher training program, 2) aims of Comparative Education teaching, 3) curricular and course titles, 4) teaching methods and textbooks, and 5) current issues and problems currently laid on Comparative Education in Korea designated by actual lecturers and professors who are in charge of Comparative Education lectures. The historical development of Comparative Education in Korea will be briefly presented at the beginning part of the chapter. To gauge the comparative position of Korean Comparative Education, the second half of this paper introduces the cases of Comparative Education at universities worldwide, presenting various countries' status of Comparative Education along with their developmental status. As the first research which pays an attention on the current figure of Comparative Education in Korea, it will form an impetus on why we should teach college students about comparative education and on what next step should be carried for further development of Comparative Education at universities based on the comparative understanding of other countries. Since it is in the transitional stage in terms of its development, it would be critical to have a self-analysis of the current status, which will help to lay the comprehensive understanding background for designating the future direction of its development.

The purpose of this study is to analyze mathematical tasks of Korea and the USA textbooks focused on conditions for parallelograms. In this study, structures of task, types of proof and reasoning, and levels of cognitive demand are investigated. The conclusion is as follows: First, with respect to structures of task, structures presented in the USA textbooks are more diverse. Second, with respect to types of proof and reasoning, Korea and the USA prefer IC task and DA task. And task types presented in the USA textbooks are more diverse. Third, with respect to levels of cognitive demand, in both Korea and the USA textbooks, PNC task and PWC task account most. And compared to the USA, Korea prefer algorithms. In addition, we find out implications for reconstruction of Korea textbook. It is as follows: First, with respect to structures of task and types of proof and reasoning, the diversity of composition needs to be raised. Second, with respect to levels of cognitive demand, the concentration in PNC task needs to be declined. And levels of cognitive demand on types of tasks need to be reconsidered. Third, with respect to tasks' topic and material, internal and external connectivities of mathematics need to be strengthened.

This study aims to compare and analyse computer curriculum and textbooks of South Korea and North Korea in order to provide the basis for unifying the Informatics Education. Result of this study follows : First, there isn't any course for Informatics Education in the elementary school but it was requisitely carried 2 hours per week in secondary school in North Korea. But contents of curriculum is much different according to the level of school : genius secondary school, first secondary school, general secondary schol. In especially, Informatics Education had centered in genius secondary school. Second, in comparison of computer textbooks used in South and North Korea, we found that most contents of South Korea textbook was selected equally from all scope whereas those in North Korea were not contained the newest contents(e.g. Internet, Multimedia). But in contrast to South Korea textbook, there was BASIC programing course for improving problem-solving skills in North Korea textbook.

The study is designed to develop a educational basic pants patterns for men, and has been analyzed focusing on the university textbooks published since 2000. We also used CAD programs and virtual fitting programs to analyze the fitness of pants. To do this purpose, after choosing 7 Men's Wear textbooks, selected patterns were drawn and measured using PAD system and were compared and analyzed. Also, the appearance evaluation was examined through virtual fitting and then evaluated 21 male and female university students in their 20s. After supplementing the problems of the patterns in the existing textbooks, a pattern was developed and verified the fitness of the developed pattern. The results of comparing the proposed measurement items of each textbook for the pants pattern indicated a significant differences in terms of hip circumference of each pattern, which were between 96~105cm. A comparison of the drafting methods of each pattern showed the drafting methods for the crotch length, the front crotch extension, the back crotch extension were the difference. The results of appearance evaluation were pattern E presented the slimmest fit and pattern D presented the loosest fit. As a result of analysis of pants pattern, a waist circumference 82cm, a hip circumference 98cm, a crotch length 24cm, a pants length 104cm and a ham line width 46cm were most suitable. The development pattern was evaluated as superior to the existing pattern through the appearance evaluation of the virtual fitting.

The purpose of this study was to examine the Pedagogical Content Knowledge(PCK) of teachers and their educational practice in the category of plane figure, to make a comparative analysis of their PCK and educational practice, and to discuss the relationship between their PCK and the characteristics of their instruction. Instruction of four selected elementary school teachers was analyzed to find out their educational practice. In conclusion, the characteristics of the PCK and actual instruction of the teachers could be listed as below: First, as a result of comparing their PCK and educational practice on plane figure by applying selected analysis criteria, there was a close correlation between their PCK and actual instruction. Second, the teachers had various levels of PCK on different areas. Especially, there was a large disparity in mathematical content knowledge and knowledge of teaching methods. Third, the teachers who had plenty of PCK were more excellent in textbook reconstructing, and those who fell behind in terms of PCK were more reliant on textbooks as if the textbooks had been the Bible.

This study aims to understand the trends and characteristics of elementary science textbook research. For this purpose, among the papers published in science-related journals from 2001 to 2021, 156 studies related to elementary science textbooks were analyzed to examine the research trends on textbook analysis. The analysis criteria consisted of two major categories, 'outward feature' and 'topic.' The subcategories of 'outward feature' consist of 'year of publication,' 'target curriculum,' 'target grade,' 'science content area,' 'subject of study,' and 'publishing institution.' The sub-categories of 'topic' consist of 'comparison,' 'content,' 'illustration,' 'inquiry activity,' 'perception of textbooks,' and 'others.' As a result of the analysis on 'outer feature,' textbook-related research was conducted almost every year, and the research on the 2009 revised science curriculum, on the 3-6 grades, and on the whole field of science had the most. The science textbook researches were published not only in science education-related journals but also in other areas' journals. As a result of the analysis of the 'topic,' the number of papers was higher in the order of comparative research, content analysis, illustration, inquiry activities, and perception of textbooks. Implications for accredited textbook system of elementary science were discussed based on the analyses on the elementary science textbook research trends.
