The purpose of this study is to develop and apply the algorithm teaching materials centered on plays(ATMCP) to improve problem-solving abilities of elementary students. For this goal, the ATMCP were reviewed by the expert group and tested them out on 71 fifth-grade elementary students in Daegu, Korea during the 6 weeks. We divided students into two groups: one is the group of the ATMCP and the other is the group of conventional algorithm teaching materials(ATM). And we analyzed the change of the problem-solving ability of each group between before and after using two types of teaching materials with the Mixed ANOVA. The result showed that there was a significant difference in students' problem-solving abilities between before and after using them and the group of the ATMCP was greater improvement than the group of the conventional ATM in a problem-solving ability.

The present study aims to investigate how teachers evaluate the Korean textbook they use for teaching primary students with multicultural background. Faced with the rich variety of materials available, it is often a challenging task for language teachers to select the most suitable coursebook. It is required that they carry out a detailed and comprehensive analysis of coursebooks and evaluate them with a set of criteria to guide the process. 32 Korean teachers took part in the primary KSL textbook evaluation that aimed to identify improvement areas. They used a pro-forma specified with 51 criteria. The teachers' responses to the questions in the pro-forma were statistically analyzed to draw implications for material evaluation. The findings of the analysis suggest that the KSL textbook for primary multicultural students need to be improved at the internal and external levels. Implications are discussed with focus on material evaluation and development, and KSL teacher professional development by helping them gain good and useful insights into the nature of the textbook, and sensitizing them to features to look for in teaching and learning materials.

This paper is intended as an investigation of 5 sentence patterns which have exerted a strong influence on the English education in Korea. The 'learning grammar', which is defined as the grammar in learning materials, was compared with 'reference grammar' derived from linguistic grammar with theoretical accuracy and validity. Although the notion of 5 sentence patterns has been assumed to be vestiges of old Japan textbooks, the classification system was originally established in 1929 by C. T. Onions. Particularly, new explanations regarding 'obligatory adjuncts' and 'marked construction' were provided in the learning materials, which could be seen as examples of the reflection of linguistic grammar theories on sentence patterns. If reference grammarbooks and the fruits of linguistic grammar research are used actively, material writers can avoid the errors of grammar description and more correct learning grammar can be taught to advanced learners.

The purpose of this study is to suggest implications for the development and revision of future teaching materials for mathematically gifted students by using network text analysis of secondary mathematics materials. Subjects of the analysis were learning goals of 110 teaching materials in a gifted education center in science attached to a university from 2002 to 2014. In analysing the frequency of the texts that appeared in the learning goals, key words were selected. A co-occurrence matrix of the key words was established, and a basic information of network, centrality, centralization, component, and k-core were deducted. For the analysis, KrKwic, KrTitle, and NetMiner4.0 programs were used, respectively. The results of this study were as follows. First, there was a pivot of the network formed with core hubs including 'diversity', 'understanding' 'concept' 'method', 'application', 'connection' 'problem solving', 'basic', 'real life', and 'thinking ability' in the whole network from 2002 to 2014. In addition, knowledge aspects were well reflected in teaching materials based on the centralization analysis. Second, network text analysis based on the three periods of the Mater Plan for the promotion of gifted education was conducted. As a result, a network was built up with 'understanding', and there were strong ties among 'question', 'answer', and 'problem solving' regardless of the periods. On the contrary, the centrality analysis showed that 'communication', 'discovery', and 'proof' only appeared in the first, second, and third period of Master Plan, respectively. Therefore, the results of this study suggest that affective aspects and activities with high cognitive process should be accompanied, and learning goals' mannerism and ahistoricism be prevented in developing and revising teaching materials.

In this study, entropy definition and explanation in twelve general chemistry textbooks published in USA including what Korean universities select are analyzed. Analysis consists of two parts. One is diachronic analysis which focuses on the change between editions of same authors and the other is contents analysis composed of three sections‐ disorder in entropy definition and explanation, microstates number in entropy definition and explanation, possibility of alternative conception in learning statistical entropy and thermal entropy. As a result, the definition that entropy is the measure of disorder is denied and explanation using microstates number is introduced. Also, caution for the possibility of alternative conception that there are two different entropies is found. Reflecting the change in entropy explanation on new chemistry curriculum and reeducating teachers are meaningful on improvement of Korean chemistry education.

In the purpose of suggesting the necessity and proper method of providing the standard reference material for acquiring the aircraft pilot license, this study provides the FAA and ROKAF case study, and positively analyzes the materials of 178 pilots and student pilots who acquired the aircraft pilot license. The result of case study shows that compared to the case of Korea which the restriction on the standard reference material providing exists, the FAA(Federal Aviation Administration) and ROKAF are currently providing the standard reference material. Additionally, the result of positive analysis indicates the fact that the necessity of standard reference material providing is well recognized and its importance also found to be remarkably high. These results represent that the standard reference material providing is necessary for training competent aircraft pilots. Also, this will mitigate the current shortage of aircraft pilots due to the rapid growth of air transportation industry, and this will play an important role in preventing diverse aircraft-related accidents.

This study aims to analyze through the integrated textbooks whether writing tasks are designed to be successful in cultivating students' writing abilities in the general-purpose Korean language education. First, we established the concept and the components of the writing task based on the definitions mentioned in previous research. The analysis of the types of writing tasks revealed "free writing" and "imitation and writing" to be the most frequent types of writing tasks in both textbooks. The textbooks have only twenty-one subjects in common. And most instructions provide only themes and genres, excluding the purpose, form, quantity, and time necessary for the article or for comprehending the instructions. In these tasks, the reading passages are most often explanatory text. The scoring criteria and time were not provided for the evaluation criteria and other factors. Therefore it became necessary to express the components of the writing task as explicitly and concretely as possible to improve learners' performances.

Information-giving is very important skill in career education and career counseling. The purpose of this study was to analyse the definition and method of information-giving as a important counseling skills in the counseling textbooks. Research questions were as follows: First, what is the definition of information-giving? Second, what are the ways to give the information in counseling? 17 textbooks of counseling were reviewed. The following are the main findings. First, the definition of information-giving was summarized in two ways: (1) the meaning of information (2) the description of information-giving. The results revealed the reason why the definition of information-giving is vague and it is difficult to distinguish from other skills (ex: giving advice, providing interpretation). Second, the main methods of information-giving can be summarized as follows: (1) motivation and timing of information-giving (2) selection criteria of information-giving (3) procedure of information-giving (4) considerations of information-giving. Out of these methods, the textbooks do not provide much reference on 'selection criteria of information-giving and procedure of information-giving. These findings revealed the necessity of empirical study on the information-giving skills.

In line with the modern society where artificial intelligence has spread throughout society, the Ministry of Education decided to provide AI education in kindergartens, elementary, middle and high school classes in 2025, and develop related learning materials and textbooks from 2021. Korea currently does not have state-led AI education for kindergarten and elementary school, so there is no systematic teaching material. Therefore, this study designed and presented textbooks for pattern analysis-based computational thinking development based on the GPS curriculum, a kindergarten SW curriculum studied by Y. S. Jeong and S. E. Lim (2020). Class procedures for using the textbooks were classified as introduction activities, development activities, and organization activities. Supplementary explanations were presented by presenting textbooks and teaching aids along with explanations of each activity. In order for this study to help AI education conducted in 2025, research must be conducted to demonstrate its effectiveness through actual application in the future.
