Purpose: The purpose of this study was to identify the nursing images appearing in elementary school textbooks. Method: This study targeted 130 textbooks of 13 subjects under the 7th national curriculum for elementary schools as of December 2005. Nursing-related texts, photographs, and illustrations in the textbooks were analyzed by using a content analysis method. As for the textbook analysis, two coders thoroughly read the textbooks to record nursing-related content per coding paper, respectively. Result: The total number of nursing-related content appearing in 130 textbooks of 13 subjects was 70. More nursing-related content was exhibited in the photograph and illustration domain(N=57, 81.4%) than in the text domain(N=13, 18.6%). Nursing-related content(N=70) appeared in the order of nursing activities with 56(80.0%), nursing as a job with 10(14.3%), and others with 4(5.7%). As for the nursing image of nursing-related content, positive images weremost with 30(42.9%), followed by negative images with 21(30.0%), and neutral images with 19(27.1%). Conclusion: Nursing-related content was dealt with too little, and dependent nursing activities such as medication, and assisting roles for doctor's examinations and treatments mainly appeared. Also, the main activity place was a hospital. To introduce proper and adequate nursing activities to the students, various types of nursing-related data and material should be distributed to front line schools, teachers, main authors, and publishing companies.

In this paper, we study the inquisitive tendency in informatics textbooks for middle school students. These textbooks were written in 2009, and have been adopted in 2013 as part of the curriculum. The research is based on six textbooks, which passed qualification tests, and is mainly focused on the section 'composition and movement of information equipment', which covers contents for the student's major field of study. Romey analysis was employed to analyze inquisitive tendency in four sections - text, data, activity and evaluation. The results illustrated that some textbooks were organized in a way that exhibited a low level of inquisitive tendency for students, and took an authoritative tone. The section 'activity' showed the highest level of inquisitive tendency and the 'text' showed the lowest level. Some sections in the textbooks were found to have zero Romey measures, which stress the need for improvement.

The contents of clothing and textiles area of elementary home economics textbooks from 1948 to 1955 were investigated. Home economics of elementary school education in those days corresponds to practice acts of elementary school education in present. Practical acts has the all-around concepts of the agriculture, industry and home economics Also the knowledge or skill for actual life are teamed. Practical acts education was started from lessons of sewing for women under title of 'jaebong'. It can be said that practical acts education was started from clothing and textiles area. The home economics elementary textbooks of the year 1948 were composed of 21 units for 5th grade and 22 units for 6th grade. The textbook for 5th grade of 1953 was composed of 19 units, and one for 6th grade of 1955 was composed of 18 units. The clothing and textiles area accounts for 38.6% in 5th grade textbook, for 32% in 6th grade textbook of 1948 and for 31% in 5th grade of 1953 and 6th grade textbooks of 1955. The textbook contents of clothing and textiles area were classified into five fields of sewing, knitting. patching, embroidering and care. In 1948, textbooks were placed a great deal of weight on sewing field education as 7 units of 15 units. The 7 units for sewing fields have suitable connection to develop. But, in the case of knitting, patching or care, just groundwork of each field was included for application to actual life without vertical connection. The contents of textbooks for clothing and textiles area in 1953 and 1955 were much alike with those in 1948.

The purpose of this study is to devise a new method for examining the readabilities of textbooks and to compare the readabilities of elementary school science textbooks. Third and sixth grade science textbooks were compared in terms of word, sentence, and paragraph in this study. In the word analyses, criterion suggested by Kim (2003) who classified about 238,000 words into seven categories according to their educational importances was adopted. In this study, the words from 3rd and 6th grade science textbooks were classified into four categories, and then the kinds and frequencies of words in each category were investigated. In the sentence analyses, sentences were classified either a simple sentence or a compound/complex sentence, and the ratios of each type were calculated. The average number of words in a sentence was also calculated in the sentence analyses. The ratios of conjunctions and demonstratives were examined in the paragraph analyses. The results indicated that both the kinds and frequencies of words in 3rd grade science textbook were smaller than those of 6th grade one. However, both science textbooks were similar in the distributions of words across the four categories. The ratio of simple sentences in 3rd grade science textbook was higher than that of 6th grade one, and the length of a sentence in 3rd grade science textbook was also shorter than that of 6th grade one. Both the ratios of conjunctions and demonstratives in 3rd grade science textbook were lower than those of 6th grade one.

The purposes of this study were to analyze the contents of sulfuric acid in Science textbooks and Chemistry II textbooks, and to survey 10 pre-service teachers' perceptions who majored chemistry education related to sulfuric acid. As results, most of the Science textbooks represented that sulfuric acid was divided into two $H^+$ and one $SO_4{^{2-}}$. But this mistake might be corrected because sulfuric acid was divided into one $H^+$and one $HSO_4{^-}$. Most of Chemistry II textbooks represented ionization steps of sulfuric acid, but same mistake was represented in some of Chemistry II textbooks. $HSO_4{^-}$ is a weak acid, but some Chemistry II textbooks represented $HSO_4{^-}$ as a strong acid. As results of the survey related to pre-service teachers' perceptions, some pre-service teachers didn't know the situation of particles in sulfuric acid solution, and they were affected on by the learning of high school classrooms.

In order to make a connection in teaching similar concepts between mathematics and science in teaching similar concepts, this paper analyzed the contents related to capacity, volume, weight, and mass in the mathematics and science textbooks aligned with the national elementary curriculum. We first explored when to present such topics in both textbooks, and then analyzed in what ways the topics were addressed in terms of quantitative comparison, vocabulary, units of measurement, measurement, tools for measurement, estimation, and connections to real life. The results of this study showed that there were some aspects emphasized in common both in mathematics and science textbooks. The analysis of this study also demonstrated subtle but considerable differences according to the characteristics of two subject matters. Based on these results, this paper provides implications for elementary school teachers to consider in teaching capacity, volume, weight, and mass through mathematics and science lessons.

Since mathematical concepts are learned through the meaning of mathematical terms in school mathematics, learners must understand and use mathematical terms appropriately. However, the meaning of mathematical terms used in real life may be perceived differently from elementary mathematics textbooks, and this difference may cause confusion in learners' understanding of mathematical terms. Therefore, this study was intended to compare and analyze the mathematical terms in elementary mathematics textbooks used in Korea and a Korean dictionary. The findings revealed that the meaning of the textbooks was similar or different, and the subject indicated by each meaning was different. In this case, in order to prevent confusion among learners, it is necessary to supplement and guide each meaning by recognizing the difference between the mathematical terms in elementary mathematics textbooks used in Korea and a Korean dictionary.

This study examines the content of vectors and matrices in Artificial Intelligence Mathematics textbooks (AIMTs) from the 2015 revised mathematics curriculum. We analyzed the implementation of foundational mathematical concepts, specifically definitions and related sub-concepts of vectors and matrices, in these textbooks, given their importance for understanding AI. The findings reveal significant variations in the presentation of vector-related concepts, definitions, sub-concepts, and levels of contextual information and descriptions such as vector size, distance between vectors, and mathematical interpretation. While there are few discrepancies in the presentation of fundamental matrix concepts, differences emerge in the subtypes of matrices used and the matrix operations applied in image data processing across textbooks. There is also variation in how textbooks emphasize the interconnectedness of mathematics for explaining vector-related concepts versus the textbooks place more emphasis on AI-related knowledge than on mathematical concepts and principles. The implications for future curriculum development and textbook design are discussed, providing insights into improving AI mathematics education.

Textbooks corresponding to curriculum goals are necessary because they are specific products of curriculum and are the most important materials for teaching, learning, and evaluation. In particular, learning objectives written in textbooks should be clearly described because they play a role in promoting learning by showing learning goals to learners clearly. This study analyzed the characteristics of verbs used as predicate of learning objectives written in high school physics I and II textbooks of Korea and compared them with physics textbooks of Singapore and the United States. Results show that Korean textbooks have less kinds of verbs compared to those of Singapore and the United States, and the verbs with abstract and comprehensive meaning such as 'understand' and 'know' were mainly used. In American textbooks, it was noticeable that no verbs have been used by more than 10%. When classifying the learning objectives in the two Korean textbooks, cognitive domain accounted for 98 to 99%, and inquiry domain accounted for only 1% to 2%. With regard to physics textbooks of the United States, inquiry domain accounted for a large proportion of domains in learning objectives compared with physics textbooks of Korea and Singapore. Physics textbooks of Singapore were similar to those of Korea in that learning objectives were biased toward cognitive domain, but differed from those of Korea in that learning objectives were specifically described using action verbs.

As the rate of foreign workers increasing, the rates of their children are rising, as well. The children's native countries vary from Japan, China to Indonesia, and difficulty of learning is expected in their entering the regular education due to the differences in the contents and curriculum they had learnt. This study analyzed the science textbooks of five Asian elementary schools including Korea, China, Indonesia, Thailand, and Iran-in diversified sides focusing on the content of earth science, for the children of foreign workers. The characteristics of the elementary science textbooks of the subject countries were compared in seven criteria-the rate of earth science in the textbooks, how units are arranged, whether the earth science contents are included, the contents highly related to their socio-cultural traits, photographs, scientific inquiries, and test items. The textbooks showed numerous differences with their own characteristics, and it is expected that the children of foreign workers would face difficulties in studies taking parts in the Korean formal education. Hereupon, this study proposes the needs of development of sub-materials for the children of foreign workers adapting to schools, and reinforcement of educating teachers for understanding children, with a national plan for the children excluded from education due to problems such as an illegal residence.
