A contemplation on the extension of the pyramid in the elementary mathematics textbooks published according to the 2009 revised curriculum
Authors:   The Korean School Mathematics Society, Park Kyo Sik
Published: October 2023

In this thesis, the extension of the pyramid is contemplated through the pyramids presented in textbook ≪Math 6-1≫ published according to the 2009 revised curriculum. In textbook ≪Math 6-1≫, the pyramid is defined by presenting rough sketches of typical pyramids in an extensional definition method. This contrasts with the method of defining the pyramid by using such an extensional definition and a connotative definition method that reveals common properties of all pyramids. In textbook ≪Math 6-1≫, right pyramids whose base can not be regarded as regular polygons, and oblique pyramids are hardly presented. Nonetheless, ≪Math 6-1 Teacher's Guide Book≫ says that we have no choice but to handle oblique pyramids. In this thesis, based on these results, the following implications are presented as conclusions. First, there should be enough discussion on the extension of the pyramid in elementary school mathematics, and agreement to the results. In particular, such discussions are highly necessary in revising the curriculum. Second, in the process of realizing the intention of the curriculum in the textbook through the teacher's guidebook, the extension of the pyramid must be consistent. Third, there should be some consensus about the knowledge that elementary teachers should know about the pyramid.

A View on the Diversity of the Word and Mathematical Notation Expression Used in High School Mathematics Textbooks
Authors:   The Korean School Mathematics Society, Yang Seong Hyun
Published: October 2023

Depending on the type of textbook, the word and mathematical notation expression used in high school mathematics textbooks varied and there were also some differences on the mathematical definition and the content description methods. Not only the composition of textbooks but also various expressing ways of textbooks have significant impacts on teaching and learning of teacher and student. The diversity of expression had pros and cons like both sides of a coin. There is a positive aspect that we can pursue pedagogical diversity. Simultaneously there is a negative aspect that the possibility of acting as a learning burden exists in the viewpoint of the student and the equality of evaluation may be undermined. In this study, Preferentially we focused on analyzing the actual situation rather than judging what is more appropriate about the diversity of words and notation expressions used in mathematics textbooks which is based on the current curriculum. For this purpose, we analyzed 56 kinds of mathematics textbooks based on the 2009 revised mathematics curriculum, and presented four aspects(terms expressing, notations expression, mathematical definition, content description method) with examples about differences of the various expressions used in textbooks including ‘terms and notations’.

Authors:   The Korean School Mathematics Society, Park Jeong Mi , Park Jang Hee , Lee Joong Kwoen
Published: October 2023

Educational objectives for mathematics in the curriculum revised in 2009 and the curriculum revised in 2015 put great emphasis on practical use of math, but perception of that lacks at schools. Accordingly, this research is recognizing the need for paying attention to curriculum focusing on mathematical connectivity and is inspecting CMP curriculum which has been developed over the years to reinforce problem solving competence and improve communication skills. This study analyzes CMP textbooks published as third edition in 2014 after several revisions, focusing on equations, inequalities and functions. First, this thesis analyzes mathematical connectivity using a new analysis framework which applied the modes of representation(situations, verbal description/ tables/ graphs/ formulae) made by Janvier(1987). Second, this research analyzes connectivities between different units, various sections, other subjects and practical contents related to the real life. The results: CMP textbooks use various practical materials for specific situations. They represent twelve processes of connectivity according to the modes of representation of Janvier. The books also show relationship between equations and functions, between inequalities and functions. And CMP textbooks include other subjects and practical contents.

Authors:   The Korean School Mathematics Society, Lee Seo Bin , Kim Sun Ho , Choi-Koh Sang Sook
Published: October 2023

Since PISA2006, the computer based assessment in mathematics(CBAM) was introduced for the first times and at last PISA2015 used all items in CBAM for problem solving. In this study, we focused on which important properties were considered in constructing geometric ‘fence items’ used in PISA 2015 to find the future direction over our teacher education, especially for constructing ‘computer based assessment items.’ For the purpose of the study, we analyzed the fence items on three components such as dependency, invariant, and path found in dragging activities, within a computer environment using the dynamic Geometry Software, GSP. Also, for the future, we provided an open-ended problem related to the fence items, which we could use as the merit of computer-based environment.
Mathematics Preservice Teachers’ Conception of Teacher Discourse
Authors:   The Korean School Mathematics Society, Lee Jihyun
Published: October 2023

Teachers’ conceptions about teaching are important driving and also interfering forces which might affect their actual practice and training. This research explores preservice mathematics teachers’ conceptions of teacher discourse, through tasks analyzing and evaluating teachers’ moment-to-moment discourse moves which occur in authoritative and dialogical classroom discourse. Some facets of the preservice teachers’ conceptions were congruent with dialogical discourse: they criticized teacher’s one-way communication and ignoring students’ voices; they supported teacher’s questions probing students’ thinking and receptive attitude toward students’ wrong answers. However, some deep and subtle facets of their conceptions were more congruent with authoritative discourse rather than dialogical discourse: they positively perceived teacher’s closed, information seeking questions that funnel students’ thinking to the predetermined procedure; they emotionally resisted teacher’s questions which might facilitate dialogical engagement by allowing students to judge mathematical correctness of ideas from their peers. Preservice teachers’ conceptions of teacher discourse explored in this research provide useful foundations on which to build continuous and coherent teacher professional development programs about classroom discourse.
An Analysis of Methods for Teaching Bar and Line Graphs in Elementary Mathematics Textbooks
Authors:   The Korean School Mathematics Society, Kim Somin , Lee Jong-hak
Published: October 2023

The purpose of this study was to identify how didactic transposition (teaching and learning methods) has occurred and developed in the teaching of graphs in elementary school mathematics textbooks for third and fourth graders according to the previous and current curricula. In this study, we analyzed the units on bar graphs and line graphs in mathematics textbooks for each curriculum from the fifth curriculum to the 2015 revised curriculum and investigated the implication of statistics education deriving from didactic transposition (teaching and learning methods). We found that the detailed timing of teaching bar and line graphs was almost unchanged as the curriculum progressed. In addition, the use of technology was not actively implemented in school statistics although the curriculum emphasized the use of technology in statistical education. Lastly, the textbooks did not address the variability and distribution of data and the sample or sampling process, which are significant concepts in statistics. On the basis of the findings of this study, we suggest how to teach statistical graphs and what to consider for the next mathematics textbook.

Analysis on Features of Prospective Mathematics Teachers’ Motivation in Learning Mathematics
Authors:   The Korean School Mathematics Society, Lee Jong-hak , Kim Somin
Published: October 2023

In this study, by measuring and analyzing the motivation of prospective mathematics teachers in learning mathematics, we tried to understand the features of prospective teachers’ learning motivation and find the implications of developing expertise in terms of learning motivation. Prior research related to learning motivation identifies the three elements that consist of learning motivation as values, self-efficacy, and interest. Based on these elements, a survey tool was developed to investigate the learning motivation of prospective mathematics teachers. This survey was then carried out for 120 students in the mathematics education department of a local college. In addition, the survey asked what methods prospective teachers would choose for motivating their future students. According to the results of this study, the overall motivation of prospective mathematics teachers differed by grade (academic year) and there were significant differences between grades in self-efficacy and interest factors. In addition, the prospective teachers preferred to use interesting materials rather than inform the value of learning mathematics to induce learning motivation. Therefore, it is necessary to enhance this self-efficacy and interest in learning and to provide various material to strengthen this motivation for learning.
Mathematical Connection and Teaching Methods of Frequency Density
Authors:   The Korean School Mathematics Society, Kim Somin
Published: October 2023

This study began with the discovery of the concept of frequency density in Singapore textbooks and in a set of subject contents of the UK's General Certificate of Secondary Education. To understand the mathematical meaning of frequency density, the mathematical connection of frequency density was considered in terms of mathematics internal connections and mathematics external connections. In addition, the teaching method of frequency density was introduced. In terms of mathematical internal connections, the connections among the probability density function, relative frequency density, and frequency density in high school statistics were examined. Regarding mathematical external connections, the connection with the density concept in middle school science was analyzed. Based on the mathematical connection, the study suggested the need to introduce the frequency density concept. For the teaching method of frequency density, the Singapore secondary mathematics textbook was introduced. The Singapore textbook introduces frequency density to correctly represent and accurately interpret data in histograms with unequal class intervals. Therefore, by introducing frequency density, Korea can consistently teach probability density function, relative frequency density, and frequency density, emphasizing the mathematical internal connections among them and considering the external connections with the science subject. Furthermore, as a teaching method of frequency density, we can consider the method provided in the Singapore textbook.

Authors:   The Korean School Mathematics Society, Kim Somin , Lee Jong-hak
Published: October 2023

This study examines trends by school level, region, subject, and type centered on elementary schools when private education is perceived as a social problem due to the overheating of private education and its over-dependence. This study aims to provide a direction to ease the school mathematics education and meet the expectations of school mathematics education. As a result of this study, in mathematics subjects, the graph of private education expenses for mathematics subjects was not affected by the period and showed a somewhat consistent linear trend. In other words, we found that the private education cost of the mathematics subject was solid compared to other factors, and was not significantly affected by external variables, and was consistent. It is meaningful to examine the trends of private education costs in mathematics subjects with a comparison between the past and present and to grasp what factors and how they have changed and developed.
A Study on the Recognition and Characteristics of Mathematical Justification for Gifted Students in Middle School Mathematics
Authors:   The Korean School Mathematics Society, Hong Yong-Suk , Son Hong-Chan
Published: October 2023

This study identified the meaning of mathematical justification and its characteristics for middle school math gifted students. 17 middle school math gifted students participated in questionnaires and written exams. Results show that the gifted students recognized justification in various meanings such as proof, systematization, discovery, intellectual challenge of mathematical justification, and the preference for deductive justification. As a result of justification exams, there was a difference in algebra and geometry. While there were many deductive justifications in both algebra and geometry questionnaires, the difference exists in empirical justifications: there were many empirical justifications in algebra, but there were few in geometry questions. When deductive justification was completed, the students showed satisfaction with their own justification. However, they showed dissatisfaction when they could not deductively justify the generality of the proposition using mathematical symbols. From the results of the study, it was found that justification education that can improve algebraic translation ability is necessary so that gifted students can realize the limitations and usefulness of empirical reasoning and make deductive justification.
Analyzing Tasks in the Statistics Area of Korean and Singaporean Textbooks from the Perspective of Mathematical Modeling: Focusing on 7th Grade
Authors:   The Korean School Mathematics Society, Kim Somin
Published: October 2023

This study aims to analyze statistical tasks in Korean and Singaporean textbooks with the mathematical modeling perspective and compare the learning contents and experiences of students from both countries. I analyzed mathematical modeling tasks in the textbooks based on five aspects: (1) the mathematical modeling process, (2) the data type, (3) the expression type, (4) the context, and (5) the mathematical activity. The results of this study show that Korean and Singaporean textbooks provide the highest percentage of the “working-with-mathematics” task, the highest percentage of the “matching task,” and the highest percentage of the “picture” task. The real-world context and mathematical activities used in Korean and Singaporean textbooks differed in percentage. This study provides implications for the development of textbook tasks to support future mathematical modeling activities. This includes providing a balanced experience in mathematical modeling processes and presenting tasks in various forms of expression to raise students’ cognitive level and expand the opportunity to experience meaningful mathematizing. In addition, it is necessary to present a contextually realistic task for students’ interest in mathematical modeling activities or motivation for learning.

Authors:   The Korean School Mathematics Society, Cho Hyungmi , Noh Jihwa , Lee Gima , Kim Hee-jeong
Published: October 2023

This study explores and compares Korean and U.S. elementary preservice teachers’ analytic approaches of students’ addition and subtraction computational strategies. Twenty-six Korean and twenty U.S. elementary preservice teachers participated in the study. Participants were asked to analyze mathematical approaches and errors from students’ addition and subtraction operations. Preservice teachers’ written documents were analyzed by applying open coding and inductive coding based on the grounded theory. As a result, the pattern of error analysis and interpretation of students’ addition computations were similar for both Korean and U.S. preservice teachers whereas there were some differences in the analysis of students’ subtraction computations. Both Korean and U.S. preservice teachers had difficulties identifying students’ strategies and errors for a complicated and unconventional computational approach. Results also indicated that preservice teachers’ noticing and interpretation of students’ strategies and errors were influenced by their K-12 mathematics curriculum and teacher education program. This study suggests implications and future directions for teacher education, more contextualized teacher preparation programs and balanced connection to the K-12 curriculum.

Authors:   The Korean School Mathematics Society, Cho Seung-A , Ju Mi-Kyung
Published: October 2023

In this paper, we sought for instructional methods to guarantee equitable access to successful mathematics learning for students with a low economic status. For the purpose, we analyzed the PISA2012 data to investigate the effect of diversity-inclusive instruction and teacher-student relationship on mathematics achievement of Korean students with a low economic status. The analysis showed that there was a positive correlation between diversity-inclusive instruction and the mathematics achievement of the students. In addition, it indicated a partial mediating effect of teacher-student relationship between diversity-inclusive instruction and the mathematics achievement of the students. Further analysis is necessary to examine the effect of diversity-inclusive instruction on the achievement of students from deprived backgrounds. Based on the results, we discuss the implications for the improvement of mathematics instruction to guarantee educational equity for all students.
Analysis of preceding education for high school  subject paper-based assessment questions
Authors:   The Korean School Mathematics Society, Oh Seo-Young
Published: October 2023

According to the ｢Special law for promotion on normalization of public education and regulation of preceding education｣, which was first implemented on 12 September 2014, teachers are required to answer questions based on the achievement standards and learning content of the curriculum, and should not overlook that answering questions in a range and level outside the curriculum may cause preceding learning and preceding education. By analyzing the status of preceding education related to assessment through the analysis of paper-based assessment questions in the high school  subject, this study aimed to examine the understanding of mathematics teachers of the 2015 revised Mathematics Curriculum and the degree of implementation of the Special law for promotion on normalization of public education and regulation of preceding education in unit school paper-based assessments. To this end, we analyzed the first semester final examination questions of 95 high schools in City A in the subject of Mathematics, and classified the questions that may cause preceding education into five types. Among the five types, the most frequent types were those that did not comply with the teaching and learning methods and notes presented in the curriculum documents, the evaluation methods and notes, and the types that used terms or content from the previous curriculum. Based on the results of the analysis of the preceding education of paper-based assessment questions, this study derived implications for preventing preceding education related to assessment and discussed the importance of teacher education related to assessment.

Published: October 2023

In this digital era, the use of social media has grown very rapidly. The use of TikTok social media among teenagers is considered as a place where they can find their identity, so the presence of TikTok is a very interesting phenomenon among teenagers. This study aims to determine the identity of the use of virtual tiktok in adolescents in the Jakarta. This research method is descriptive with a qualitative approach by interviewing adolescent informants (15-24 years) in the Jakarta who actively use Tik Tok social media as a primary data collection technique and also conduct literature and documentation studies as secondary data. In the results of the study, social media users, especially teenagers who use TikTok can control various aspects of themselves that they want to be displayed in digital public spaces. There are several teenagers who fall into the real-life identity type and some for pseudonymity (real identity begins to blur and even fake), none of them have fully become anonymized in this study because each content they create is often held by themselves and things they enter into. It's also an identity because with their faces people will recognize them and it doesn't really matter to them if there are other teenagers who choose to become different (anonymity).
Consumption of signs in preloved cultural practices among Generation Z in market places
Authors: Rahmah Hilda , Fanani Fajrian Noor , Pamung Yoma Bagus
Published: October 2023

This research aims to determine the form of sign consumption in preloved cultural practices among Generation Z at the Shopee marketplace. This research uses the ethnographic method to highlight community or community activities in a virtual space. In this case, Generation Z, aged 19-26, is active in the preloved culture at the Shopee marketplace. Massively increasing preloved practices among Generation Z marketplace users have brought a new discourse. Preloved is a term used to define and classify privately owned clothing that is resold. Usually, preloved goods offer quality from well-known brands, thereby attracting consumer appeal, especially for Generation Z. Generation Z consumers have a decision-making style that is sensitive to brands, prices, perfectionists, emphasizes quality, hedonic, impulsive, and loyal, so that in practice they often target branded goods, even though they are not new or can be called preloved. Symbolically, preloved fashion items, often the target of Generation Z, become an alternative to fulfill their desire to show their self-image through the brand they wear. In line with Baudrillard's perspective, this practice is not only done to meet needs but is simultaneously used to consume signs and symbols that emphasize the brand attached to the goods. Furthermore, the consumption of signs by the Z gene shows the form of social capital (building networking), economic capital (financial security), culture capital (interpersonal skills), and symbolic capital (recognition), where this capital becomes capital accumulation for gen Z in its efforts to adapt and social mobility in the digital age.

Data were collected from 761 Thai runners experienced in a running event in tourist destinations. The questionnaires were tested using Cronbach’s Alpha of attitude toward eco-run events, satisfaction, and loyalty, .941, .943, and .929, respectively. The data were analyzed by the structural equation model. The results illustrated 11 key attributes being a new concept managing running events responding to sustainable tourism. The paper found positive effects among the 11 attributes, satisfaction, and loyalty. Consequently, applying the key attributes can enhance tourist runners' satisfaction and loyalty. The results can make contributions to organizers, CBT, and academics in organizing an eco-run event sustaining tourism.

Education is a fundamental human right crucial for individual growth and societal progress. In Somalia, modern education started during the colonial era with a focus on producing clerical workers for the colonial administration. Western Christian missionaries arrived to establish "modern schools," but suspicions of Westernization and proselytization led to their expulsion. This case study delves into the history of Somali education, highlighting persistent conflicts over objectives, management, and outcomes. Disagreements persist over language of instruction, curriculum unification, resource sharing, and mandates, hindering effective education implementation. The study adopts a qualitative case study approach, collecting data through interviews to shed light on the complex issues plaguing Somalia's education system. It emphasizes that the system remains rudimentary and reliant on external support due to insufficient local investment and ownership. Notably, the research reveals that parents and guardians invest more in their children's education than the government, challenging the belief that donor organizations heavily fund education in Somalia. The study proposes key recommendations. First, it calls for prioritizing education to meet the needs of all school-age children, including the millions out of school. Second, it suggests increasing the education budget to 20% of the Gross Domestic Product (GDP), aligning with neighboring countries' norms. Third, it advocates for clarifying constitutional mandates, roles, responsibilities, and resource sharing at all government levels. In summary, education's pivotal role in human development and societal advancement is underscored in Somalia's context. The study's findings illuminate the historical struggles and current challenges facing the education system, emphasizing the need for increased investment, clear mandates, and resource allocation to ensure quality education for all Somali children and youth. Keywords: History of Somali education, modern education, literacy campaign, post-conflict education, education in fragile states.

Syphilis is one of the oldest known sexually transmitted diseases. Despite numerous scientific studies, syphilis infection affects humanity. The relevance of the syphilis problem is primarily determined by social factors. For hundreds of years, the incidence of sexually transmitted diseases, including syphilis, has been increasing in times of social disruption, such as wars, environmental disasters, etc. We should expect their growth at present, the time of the Ukrainian-russian war. Cases of early forms of syphilis are already being registered.The elimination of specialised medical institutions and uncontrolled treatment of syphilis patients will lead to an increase in the incidence of latent forms with damage to the nervous system, internal organs, musculoskeletal system, etc. As a result, it will cause the loss of working capacity, disability, and mortality. Undoubtedly, patients will be treated mainly on an outpatient basis with penicillin of prolonged action.The publication is devoted to the description of a clinical case of latent cerebral meningovascular syphilis in a patient who had been treated for early latent syphilis for 12 consecutive years. The probable cause of neurosyphilis, in our opinion, is the patient’s use of a durant drug to penicillin (benzathini benzylpenicillinum). We cannot ignore the resistance of Treponema pallidum to antibiotics and the specifics of the interaction between the syphilis pathogen and the patient’s immune system.With this message, we draw the attention of family doctors, neurologists, dermatovenerologists and other specialists to the possible increase in syphilis incidence due to the war of russia against Ukraine. Parenteral administration of penicillin antibiotics in hospital setting, followed by long-term serological monitoring, remains the method of choice in the treatment of syphilis. Treatment of syphilis with durant drugs of penicillin should be carried out as an exception. Long-term results of treatment with these medications indicate relatively frequent cases of complications, such as neurosyphilis, visceral and early latent syphilis, etc.

To reduce the energy density of the ballast cleaning machine drive, it is necessary to evaluate the load affecting the drive of the bar device, since it is the most loaded while cutting the ballast. To obtain and evaluate the drive parameters during operation, it is proposed to use computer modeling methods using software complexes. To form the initial data when modeling the drive, it is necessary to study the process of interaction of the ballast with the bar chain of the cutting tool, which will allow to find out the nature of cutting. According to LS-Dyna, it was possible to determine that the load during modeling is sinusoidal, which corresponds to the experimental studies conducted in this area. In addition, it was found that during the operation of the bar working body, cutting forces decrease when dragging the scraper sole along the ballast layer. The use of FestoHydrolic software made it possible to find a sinusoidal load affecting the drive of the cutting tool, and the amplitude of changes in its parameters is also evaluated.
Pairwise Regression Weight Contrasts: Models for Allocating Psychological Resources

Published: October 2023

Researchers examine contrasts between analysis of variance (ANOVA) effects but seldom contrasts between regression coefficients even though such coefficients are an ANOVA generalization. Regression weight contrasts can be analyzed by reparameterizing the linear model. Two pairwise contrast models are developed for the study of qualitative differences among predictors. One leads to tests of null hypotheses that the regression weight for a reference predictor equals each of the other weights. The second involves ordered predictors and null hypotheses that the weight for a predictor equals that for the variables just above or below in the ordering. As illustration, qualitative differences in high school math course content are related to math achievement. The models facilitate the study of qualitative differences among predictors and the allocation of resources. They also readily generalize to moderated, hierarchical, and generalized linear forms.
