That heterosis is a genetic phenomenon cannot be doubted. Recently many have however, studied the specific physiological-biochemical reactions and mechanisms responsible for the superior growth and develop. ment in the hybrids of various crops. For studying these specific reactions responsible for hybrid vigour, attention should be focussed on the actual stage at which the heterosis is manifested in growth and the degree of its manifesta- tion. The study of relative growth rate, leaf area and dry matter accumulation are interesting fields for understanding the phenomenon of heterosis and the stage of manifestation of hybrid vigour.

Pumkin (Cucurbita moschata Poir.) is one of the important vegetable crops of Tamil Nadu. It is valued mostly as a vegetable and is also used as a main ingredient in the preparation of sweet-meats, thus providing opportunities for processing and canning industries. Yet, there has been so far no improved strain in pumpkin for cultivation in Tamil Nadu Breeding projects were, therefore, undertaken at Agricultural College and Research Institute, Coimbatore for evolving an improved strain of pumpkin combining high yield, better fruit quality and desirable agronomic characters and the results are presented.
Evaluation of Nine Maize varieties for Intervarietal Hybridization
Authors:   Research Assitant, Punjab Agricultural University Ludhina, S KUMAR
Published: October 2023

The technical difficulties in the production of double cross hybrids have been a serious problem for slow coverage of the total maize area under cultivation. The evaluation of inbreds makes the procedure costly. The development of the varietal hybrids seems to be a quick approach to ensure the high yields of maize in comparatively short time and with the least expenditure. The heterosis expressed by the genetically diverse varietal crosses can be exploited and the success of which will depend on the efficiency with which the superior varietal crosses can be detected.
Effect of plant growth regulators on jack (Artocarpus heterophyllus Lamk.)
Authors:   Annamalai University Annamalainagar 608 002 TamilNadu., K.G SHANMUGAVELU
Published: October 2023

Plant growth regulators are known to make effects on plant growth and development. One of such effects is to induce seed germination and to influence shoot and root growth of the plants. During the past four decades voluminous literature has accumulated on the subject. However, little attention has been paid on jack (Artocarpus heterophyllus Lamk.). Sonwalker (1951) had made some studies on the germination of jack seeds and reported the slow growth of the seedlings. Recently, Sinha and Sinha (1969) studied the effect of NAA on the germination of jack seeds. Investigations were undertaken to study the effect of plant growth regulators on seed germina- tion and the root and shoot development of the jack seedlings.

In our country mango occupies an important place in horticulture and covers maximum acreage under any single fruit crop (around two milion acres). The acreage under grafted mango trees of commercial varieties has been gradually increasing in recent years and enlightened growers are increasingly alive to the research findings. In spite of various problems, there has always been good scope of mango export to foreign countries and hence the mango planting is to be viewed from the commercial angle and to give it an industrial orientation. Successful mango cultivation is beset with many intricate problems which have to be properly investigated and tackled in order to put the mango industry on a sound footing. Among the various problems rootstock selection is a vitally important subject for successful orcharding.

Published: October 2023

P is known to exist in organic and inorganic forms in soils. Among the various fractions of inorganic P, phosphates of aluminium, iron and calcium are considered to be important from the point of view of fixation and availability of P in soils. The rate and quantity of P that becomes soluble from these sources under various soil and environmental conditions determine the P status of a soil. Evidence is ample in literature to indicate that distribution and availability of P depend largely on the forms of soil P. Since the different forms of soil P have different solubilities, the forms and distribution pattern might give an indication about the availability of P in the soil. Though much work has been done on the chemistry and behaviour of P in acid soil, due attention has not been paid to soils of alkaline reaction. Therefore systematic investigations are considered necessary to gain an insight into the various phenomena of P behaviour in alkaline soils and the present work refers to a study with Tamil Nadu soils.

One of the most important properties of a metric character is the heritability. It is expressed as the proportion of total variance that is attribut- able to the average effect of genes and it determines the degree of resemblance between relatives. But the most important function of the heritability in the genetic studies of quantitative characters is its predictive role. It expresses the reliability of the phenotypic value as a guide to the breeding value. We can only measure phenotypic values of the individuals and the performance in the following generation will be determined by the breeding value. The possible advance through selection based on phenotypic values can, therefore, be predicted only from knowledge of the degree of correspondence between phenotypic value and breeding values. This degree of correspondence is measured by the heritability estimates. The heritability estimates enter into. almost every formula connected with breeding methods and many practical decisions about the techniques to be followed depend on its magnitude.

It has been the experience of many Research workers engaged in the study of rice blast disease that considerable difficulties are being encountered in securing sufficient amount of sporulation in culture while multiplying the pathogen for inoculation purposes. It is also known that unless the spore load is of sufficient magnitude successful results are not often obtained in pathogenicity tests. Although certain media like host-leaf extract, rice straw, barley seed, rice polished agar etc., have been suggested by different workers in other countries, it was not always successful to obtain abundant sporulation of the pathogen by using the above mentioned media under conditions existing at this centre. To a certain extent it may perhaps be due to variations in the environmental and other conditions prevailing here. But the suitability of the medium appears to be an important single factor that influences the extent of sporulation. With this object in view, different media were tested to ascertain their suitability for growth and sporulation of Pyricularia oryzae under laboratory conditions. Experi- ments were also conducted to find out the optimum incubation period for maximum sporulation. The size of condia produced in different media was also determined with a view to observe variations if any. The results obtained in these experiments are presented in this paper.

Published: October 2023

The response of a genotype to the external application of gibberellic acid (GA) is an index of the level of endogenous gibberellin content (Ecklund and Moore, 1968). Radio-sensitivity of a genotype depends upon the changes in endogenous levels of auxin and ascorbic acid (Sparrow and Christensen, 1953). To find out the differences in radio-sensitivity, if any, of the two sub-species of Oryza, and to correlate with their response to the external application of GA, an experiment was conducted in two varieties of paddy viz., Ss and Taichung-65 belonging to indica and 'ponlai' groups respectively.

Rodents are one of the serious pests of rice crop. Various chemical and mechanical methods of control of the rodents have been tried by many workers, but none of them proved effective, especially for protecting the crop from migratory rats. Hence the efficacy of providing electric fence, for pre- venting rat damage in rice crop was tested at the Regional Agricultural Research Station, Aduthurai during 1969 and 1970. The results are presented hereunder. Electric fence is being used in the western countries for preventing wild animals from entering cultivated fields. It, is also in use for regulating grazing space in the pasture lands. The electric fence energised by battery is in use at the International Rice Research Institute, Philippines and is found useful for preventing the rat damage to rice crop (I.R.R.I. Annual Report, 1965) There is also a report of the efficient use of the electric fence in the Bangkok Rice Experiment Station at Thailand, for protecting rice crop from field rats (Anon., 1967).

Co-operative credit societies are considered as the most suitable institutional agencies that provide credit and other inputs to agriculturists. In Tamil Nadu, almost all the villages have been covered by Co-operative credit societies which serve the needs of the farmers in the rural areas. A study on the working of these societies however, reveals that while a few of the societies have been highly successful in achieving the objectives, many of them continue to function against several odds. It will therefore, be of great interest to study the working of a society that functions efficiently in serving the needs of the rural people on whose faith and confidence the success of the society depends. The Thudiyalur Co-operative Agricultural Services Ltd., is one of the rural co-operatives which has shown a steady progress in serving the interests of the farmers and its devoted service to the agriculturists in and around Thudiyalur in Coimbatore District has been well recognised both by the Government and the public.

Objetivo: Describir los factores de riesgo vinculados al almacenamiento excesivo de medicamentos en hogares urbanos de una región en México. Material y Método: Utilizando una encuesta virtual, se recopilaron datos sociodemográficos de los miembros del hogar y detalles sobre los medicamentos almacenados. Los datos se analizaron mediante medidas de tendencia central, dispersión y pruebas de Odds Ratio y Chi cuadrado para analizar asociaciones significativas entre variables. Resultados: De un total de 300 hogares encuestados, el 20% tenían niños menores de cinco años, el 25,3% tenían adultos mayores y el 78,5% disponían de seguridad social. Además, se observó una mayor prevalencia de analgésicos (99%), antiinflamatorios (92%) y antipiréticos (89%) en comparación con otros grupos de medicamentos. La mayoría de las familias optaba por contenedores de plástico para almacenar los fármacos. El 51% informó poseer medicamentos caducados en sus hogares, pese a que todos los encuestados hayan afirmado seguir buenas prácticas en relación con el almacenamiento. Conclusión: Se determina que los adultos mayores, la seguridad social y la presencia de enfermedades crónicas son factores de riesgo significativos para el almacenamiento excesivo, siendo la acumulación de medicamentos
caducados, una consecuencia de tal fenómeno.

This thorough review paper aims to provide a nuanced picture of the post-pandemic HRM landscape by critically analyzing 30 academic works. The findings' synthesis reveals a dynamic environment characterized by agility, digital transformation, worker wellbeing, and strategy alignment. Businesses have used technology to improve communication, streamline operations, and enable remote work. Additionally, the epidemic has highlighted the significance of employee wellbeing, leading to the establishment of inclusive leadership and a culture. HRM practices have developed into strategic partners that support innovation and align with corporate objectives. This review study highlights the adaptation and resilience exhibited by organizations and provides helpful guidance for navigating the changing HRM paradigm in the post-COVID-19 environment.
Reasonable Compensation for Creative Labor: International Practices and Precedents of Audiovisual Author’s Unwaivable Right to Remuneration
Authors:   Korea Copyright Commission, Park Kyung Sin
Published: October 2023

For copyright to achieve its original purpose, creators should be entitled to fruits of successful exploitation of their work after they license or transfer their rights. Due to imbalance of bargaining power, creators often sign away their rights to compensation. To respond that, we need to think about legislating an unwaivable right. Its operation resembles the fee collecting systems already set up for television writers and actors in Korea and for music writers and performers around the world, which originate from historical reasons, collective power, or the statutory compensation for performing music recordings. The last example is enshrined by Rome Convention and WPPT, and its modus operandi can be easily applied to audiovisual recordings. When the 2016 Beijing treaty does exactly that for audiovisual performers (i.e., actors and actresses) and where digital technology makes collection of fees for various ways of communicating the audiovisual works to the public, the time is ripe to seriously consider the audiovisual authors’ unwaivable right to remuneration extending beyond performers and inclusive of directors and script writers. In doing so, it will be desirable to take the form of compulsory licensing for copyright limitation so that the right to remuneration exists even when the creators have not made licensing or transfer. Collective management societies’ collecting activities may be more efficient than filing lawsuits for copyright infringement.
French Copyright Contract Law Review
Authors:   Korea Copyright Commission, Yang Daeseung
Published: October 2023

Contracts for use of copyrighted works mainly appear in the form of transfer of rights or license to use. However, the concept of ‘Cession’ under French copyright law is not understood to be the same as the concept of ‘transfer’ under Korean copyright law. ‘Cession’ can be seen as transferring only the right to use, excluding the right to profit or disposal. In this respect, ‘Cession’ is closer to the concept of ‘Concession’, which is understood as the concept of ‘permission to use.’ Meanwhile, French copyright law interprets the contents of the copyright agreement related to ‘Cession’ very strictly. It stipulates that comprehensive transfer of rights to future works is invalid, and compensation to authors is based on proportional compensation, and fixed compensation is recognized only as an exception. Even in the case of fixed compensation, if the loss suffered by the author is more than 7/12 due to profit imbalance or failure to sufficiently predict the profits to be received from the work at the time of contract, a change in compensation may be requested. In addition, in a copyright contract, not only must each right that is the subject of the contract be individually stated, but also the area of use of the rights that are the subject of the contract in the copyright contract must be specifically determined according to the scope, purpose, location and period. In this respect, it can be seen that French copyright contract-related regulations do not entirely entrust the contractual relationship between authors and users to the principles of private autonomy or freedom of contract. The principles of the French usage contract system place greater emphasis on the principles of contractual fairness, focusing on protecting the weak author. The contents of the provisions related to copyright use contracts under the French Copyright Act can be used as important basic data not only in understanding the content and purpose of the French Copyright Act, but also in reflecting on our copyright use contract system. In particular, this study has significant implications in relation to legislation to create a fair copyright contract culture surrounding the amendment to the special provisions for video works that has recently b een d iscussed in Korea.
Changes and Implications of the Rights of Music Performers in France: Focusing on Transmission Rights and Remuneration
Authors:   Korea Copyright Commission, Lee Won
Published: October 2023

This study examined how the legal rights of French music performers have changed, especially in the recent series of legal and institutional innovations related to the French music industry, and what their implications are. French performers formed two groups in the 1950s and have been negotiating with record producers to protect and strengthen their rights. In France, the legal status of performers was established when neighboring rights were recognized in 1985. With the passage of the EU Copyright Directive in 2019, a legal order was enacted to reflect this directive in French domestic law in 2021. Based on this order, music performers in France were promised unprecedented minimum remuneration from streaming. It was also guaranteed the right to request transparent information disclosure from users and the right to request additional remuneration after transfer. The implications of this study are as follows. French performers have strengthened their rights to this day through collective solidarity. This is the background of improved amendments to performance rights in the European Union guidelines or French copyright law. The remuneration is an absolutely important part of the income of French music performers. In other words, the right to claim remuneration is making a substantial contribution to performers with relatively weak rights. In a highly digital society, the right to transmission has become the most important exclusive right. The fee rate for music performers’ transmission rights has long remained at the lowest level. The French agreement reached in 2022 dramatically improved the unfairness of streaming fees for music performers.
The Implications of the Andy Warhol Foundation v. Goldsmith Ruling by the United States Supreme Court
Authors:   Korea Copyright Commission, Shin Chang-Hwan
Published: October 2023

The recent United States Supreme Court ruling in Andy Warhol Foundation v. Goldsmith (2023) has clarified the concept of fair use. The Supreme Court ruling can be summarized as follows: “In the United States Copyright Act, the first factor in determining fair use is the purpose and character of the use. Transformativeness is the degree to which the use has a different purpose and character from the original work. Transformativeness is evaluated by considering the two factors of ‘commercial character’ and ‘justification of use’. If transformativeness is found, it means that the first factor of fair use has been passed favorably. Additionally, for fair use to be recognized overall, especially in relation to the first factor of the purpose and character of use, it must be reviewed in the context of the specific use of the relevant case. In the case of specific use, if the purpose of the original work and the subsequent work are different, fair use may be established.” When compared to the Google ruling of the United States Supreme Court in 2021, there is a greater possibility that the justification of use related to compatibility, standards, and efficiency will be recognized in technical cases, but the justification of use of another's work is relatively less likely to be recognized in artistic cases where the individual expression of the artist is the main part. In this regard, it is also noteworthy that the distinction between ‘technical transformativeness’ and ‘artistic transformativenss’ may be regarded as established by recent US case laws.
Copyright Law Issues Related to Investigating a Potential Infringement of Free and Open Source Computer Programs
Authors:   Korea Copyright Commission, Kang Gi Bong
Published: October 2023

Since access control technological protection measures fundamentally block access to copyrighted works, the user of the copyrighted work is prohibited from using the copyrighted work in any way, regardless of his or her will, outside of the scope of use set by the copyright owner. However, copyrighted works are used in various ways to shape the culture of our society. In particular, free and open source software (“FOSS”) contributes to the improvement and development of software-related technology and culture in our society by sharing the source code so that anyone can use i t. In addition, FOSS is currently developed not only as a means of information sharing, but also as a way to promote a company or expand its market share, and from the developer’s point of view, their reputation or market share is an important incentive.
However, when a person who develops a computer program using FOSS uses technological protection measures for access control to protect his or her computer program, it may become difficult to investigate whether a particular computer program includes FOSS, and if so, whether the use of the program complies with applicable license terms. In this case, the social function or role of FOSS may be reduced or damaged.
A sound and effective ecosystem for FOSS needs to be formed in Korea. Therefore, in order to ensure investigation activities to identify potential violations of the FOSS license and copyright infringement, it is necessary to stipulate exceptions that allow the circumvention of access control technological protection measures. However, it is necessary to properly configure the requirements for exceptions in order to minimize problems that may arise accordingly.
A Study on Copyright Issues related to NFT (Non-Fungible Token)
Authors:   Korea Copyright Commission, Yoon Youngjin
Published: October 2023

This study examined the technical characteristics of NFT, such as the concept of NFT, its history, and the distinction between NFT and NFT contents (Chapter 2). And as a preliminary review to discuss the legal issues of NFT, the productibility and the copyrightibility of NFT and NFT contents were reviewed (Chapter 3). NFT includes NFT metadata and NFT content. Under the current law, the productibility of NFT metadata and NFT content is denied, but NFT metadata has a high possibility of scarcity, exclusive control, and independent trading, so it was argued that property law protection could be possible with future amendments to the law or changes in interpretation theory. Copyrightibility of NFT metadata will be denied, but it is determined that NFT content can be recognized as copyrightable according to its contents. Based on the discussion in Chapter 3, the copyright law issues raised by NFTs were reviewed (Chapter 4). First, we looked at NFT-related copyright dispute cases that are becoming a reality, and selected and examined representative cases of digital copyright infringement that are expected to have significant implications in NFT-related litigation, focusing on relatively recent cases. Based on the review of these cases, aspects of copyright infringement that are expected to occur during the transaction and creation of NFTs are analyzed and listed in detail from the objective and subjective perspectives. Specifically, the series of processes of creating and storing NFTs without the permission of the copyright holder is highly likely to include a commercial use process, and therefore may constitute infringement of Author’s Property Rights and Moral Rights depending on the method or content of use of NFT content. In addition, advertising and posting NFTs on NFT trading platforms appears to be an act of aiding and abetting the act of providing them to the public commercially and continuously because the NFTs contain a URI that links to NFT content that infringes copyright.

Published: October 2023

This study used a completely randomized design with a sample of 525 Anopheles sp. larvae. which were divided into 7 groups and 3 replicates, which contained 25 Anopheles spper larvae. Except for the control, each group was given clove leaf infusion starting from a concentration of 0.50%, 1%, 2%, 4% and 6%, where the treatment was carried out for 24 hours. The results showed that there was a larvicidal effect of brewing clove leaves (Syzygium aromaticum L.) on the mortality of Anopheles sp mosquito larvae, where the effective concentration was 6% and had an LC50 value in killing Anopheles sp larvae of 0.89%. The overall phytochemical content of clove leaves which has a fast response to the mortality of Anopheles sp. are saponins, flavonoids and tannins which are capable of acting as larvicides through the mechanism of damaging cell membranes or interfering with larval metabolic processes. The content of saponins, flavonoids and tannins can increase the mortality of Aedes aegypti L. larvae through the mechanism of damaging cell membranes or interfering with larval metabolic processes as stomach poisoning.

The Effects of Heterogeneity between Nationwide Coalition Scholastic Ability Evaluations and CSAT Mock Tests on School Education_Focused on the Mathematics Section
Authors:   The Korean School Mathematics Society, Yang Seong Hyun
Published: October 2023

Most enrolled students arranging for the College Scholastic Ability Test(CSAT) prepare it through two types of mock tests during the year of the third grade. One type is the Nationwide Coalition Scholastic Ability Evaluation(NCSAE) conducted four times by the city and provincial office of education, the other type is the CSAT June and September Mock Test administered by the Korea Institute of Curriculum and Evaluation(KICE). However, these two types of tests are highly heterogeneous evaluations with many similarities. In this study, based on the analysis results of 2016 NCSAE grading statistics published by Seoul, Incheon and Gyeonggi provincial office of education and those of 2017 CSAT June and September Mock Test released by KICE, we analyzed the heterogeneity between two types of mock tests focused on the difficulty level. Based on this analysis, we examined mathematics section scores of 2016 NCSAE(March, April, July, October) and 2017 CSAT June and September Mock Test of 161 students in two high schools in Seoul and investigated the change of enrolled students grades according to the change of the test group. Through this, we sought to draw implications for the educational policy that should be accompanied necessarily in order to improve the item building system of the NCSAE.
Analyzing the Status of Students' Learning on Mathematics Related Contents of Animal Resources Curriculum in Agricultural High School
Authors:   The Korean School Mathematics Society, Cho Eun Ah , Do Jonghoon , Park Yun Beom
Published: October 2023

Although it is not necessary to have much mathematical knowledge in major courses of Animal Resources curriculums in agricultural high school, the function of mathematics class has a much effect on major courses. Therefore, we extracted the mathematics contents included in major courses of Animal Resources curriculums in agricultural high school, and also evaluated students’ understanding according to the description method in textbooks of major courses. Furthermore, we analyzed students’ preference about the description method in textbooks related to the major courses. As a result, it turns out that the level of mathematics contents of Animal Resources major curriculums does not break bounds of middle school level. Furthermore, many students are not able to solve the middle school level of problems. It is also shown that the most preferred description method in textbooks of Animal Resources major curriculums is the sentence-equation mixed type. In this study, we propose to reconstruct the mathematics contents with basic knowledge needed to complete the major courses in order that students can complete them more easily, and furthermore, to choose the description method in textbooks of major courses as sentence-equation mixed type and detailed explanation about terms should be included into the bargain.
예비 고등 수학교사들의 Geometer’s Sketchpad를 이용한 수업 시연에 관한 다중 사례 연구
Authors:   The Korean School Mathematics Society, Kim Somin
Published: October 2023

This is a multiple-case study of how preservice secondary mathematics teachers teach a particular mathematics using a technological tool. In a performance interview, the preservice teachers demonstrated how they would teach a specific mathematical topic using Geometer’s Sketchpad. The results of this study showed that the preservice teachers designed diverse types of lesson plans and implemented different pedagogical and technological techniques in their teaching demonstrations. The findings suggest that preservice teachers’ pedagogical content knowledge is an important factor in the integration of technology into their mathematics teaching. Thus, mathematics teacher educators should help preservice teachers gain a robust pedagogical content knowledge in order to effectively teach mathematics with technological tools.

However, there were positive effects in the other five grades. Second, in terms of satisfaction, the proportion of students who were 'generally' was 89%. the proportion of students who were 'not generally' was 3%. Study subject students were found to be generally satisfied with the STEAM-based instruction.
The Analogical Discovery from Inscribed and Circumscribed Circles of a Triangle to Inscribed and Circumscribed Spheres of a Tetrahedron Through the Analytical Method
Authors:   The Korean School Mathematics Society, Kim Keun-Bae , Choi Ok-Whan , Park Dal-Won
Published: October 2023

This study targeting 10 high school 3rd grade students who have studied space figures in natural sciences track analyzes the process of analogical discovery from the construction of inscribed and circumscribed circles of a triangle to that of inscribed and circumscribed spheres of a tetrahedron through the analytical method using Geogebra. The subjects are divided into two groups of five, the experimental group consisting of those who have experienced analytical method and the comparative group consisting of those who haven’t. This research is a case study analyzing the process of constructing inscribed and circumscribed spheres of a tetrahedron. Although students of both groups all have an accurate preliminary knowledge of inscribed and circumscribed circles of a triangle, they have difficulty in constructing inscribed and circumscribed spheres of a tetrahedron. However, the students of experimental group who have studied the constructing process of inscribed and circumscribed circles of a triangle in reverse using analytical method and Geogebra can perform analogical discovery finding out the way to construct inscribed and circumscribed spheres of a tetrahedron using analogy by themselves. They can control and explore with a complete picture by visualization. Also, they can immediately examine and provide feedback on the analogizing process of their own. In addition, the process affects the attitude of students toward mathematics positively as well as gives validity to the result of analogy.

Authors:   The Korean School Mathematics Society, Chang HyunSuk
Published: October 2023

This research is an analysis of communication that occurs during the quadratic function teaching and learning process of middle school students, which reflects mathematical modelling. For in-depth analysis of the communication, Sfard(2008)'s discourse theory and language analysis framework(Chang, Kim, Lee, 2019) were applied. A quadratic function mathematical modelling teaching and learning was conducted for the week 2nd(1 hour) in June 2019 for students who studied the concept of quadratic function and who passed a certain period(3 months). The results are as follows. First, The commo-gnitive conflict occurred because of differences in prior knowledge other than quadratic function among students. Second, in the course of communication, knowledge was expanded through problem solving from different perspectives. These results can be interpreted as allowing students to clearly reveal problems in the communication process based on their understanding of the concept of quadratic functions and to facilitate cooperation among students.

This study analyzed characteristics of prospective teachers' HCK related to understandings of inverse function symbol. The aim of this study based on the analysis was to deduce implications of developing HCK in terms of the means which would enhance mathematics teachers' professional development. In order to achieve the aim, this study identified features of HCK by examining the previous literature on HCK which has conformed Ball & Bass(2009) and exploring the research in AMT including Zazkis & Leikin(2010) which has emphasized cultivating AMT through university mathematics education. In addition, a questionnaire was developed with reference to the features of HCK and taken by 57 prospective teachers. By analyzing the data obtained from the written responses the participants presented, this study delineated the specific characteristics of the teachers’ HCK with regard to inverse function symbol. Additionally, several issues in the teacher education for improving HCK were discussed and the results of this research could provide inspiration for designing and implementing a teacher education program relevant to HCK.
What Do Pre-service Teachers and In-service Teachers See from Korean Mathematics Classroom?: International Classroom Lexicon Project
Authors:   The Korean School Mathematics Society, Cho Hyungmi , Kim Hee-jeong
Published: October 2023

Lexicon is closely related to human thinking. In particular, a classroom lexicon results from objectifying the teaching-learning activity in classrooms, allowing humans to recognize and explore the activities and phenomena in classrooms explicitly. Therefore, using the lexicon and clarifying what the words mean is to enhance the understanding of teaching activities. The International Classroom Lexicon Project investigates and identifies each country's mathematics classroom lexicon, where ten countries participated. The purpose of this current study is to compare the differences in perceptions between teachers and pre-service teachers about the Korean classroom lexicon previously investigated as a part of the international collaborative project. By comparing the responses of 147 teachers and 127 pre-service teachers, the degree of familiarity with pedagogical terms and the frequency of occurrence or usage in classrooms were compared and analyzed to understand the recognition of pre-service teachers' pedagogical terms. Finally, we also discuss reflections on Korean mathematics teaching practices in Korea.

Published: October 2023

The goal of this study was to analyze students' views about statistical themes in Mongolian secondary schools in Ulaanbaatar. To this end, 129 9th grade students were stratified random sampling at two secondary schools in Ulaanbaatar, Mongolia, and a survey was conducted on them. The attitude survey focused on six factors contributing to the attitude: affective, cognitive competency, value, difficulty, interest, and student effort. The results show that students believed their statistical knowledge and skills have increased compared to the beginning of the courses. Furthermore, the survey revealed that they perceived statistics as neither an easy nor a difficult subject. Students' interest in statistics was neutral in general. These results suggest a need to develop effective and innovative statistical teaching and learning methods that can attract attention to statistical topics.
Development of mobile, online/offline-linked math learning content to promote group creativity
Authors:   The Korean School Mathematics Society, Kim Bumi
Published: October 2023

In this study, in order to support the expression of group creativity of high school students, we developed mathematics learning contents linked with mobile and online/offline that obtain the maximum and minimum values ​​of the function within a limited range. This learning content was developed in connection with the ‘environment’, a cross-curricular learning topic. We explored the concept of group creativity in school mathematics. Its manifestation process, elements of group creativity expression process, and mobile and on/offline implementation functions were also explored. Then, we developed a hybrid app, ‘Making the Best Box that Thinks of the Earth’, which can express group creativity through mobile and online/offline-linked cooperative learning. A learning management system (LMS) and a teaching and learning guidance plan were also developed to efficiently operate mobile and online/offline-linked math learning using the app in schools. Our study found that the hybrid app, ‘Creating the Best Box that Thinks of the Earth’, was suitable for promoting group fluency and group sophistication based on complementary-metacognitive interaction.
Analysis on Contents and Problem solving methods of Fraction Division in Korean Elementary Mathematics Textbooks
Authors:   The Korean School Mathematics Society, Lee Daehyun
Published: October 2023

The contents of fraction division in textbooks are important because there were changes in situations and problem solving methods in textbooks according to the revision of the curriculum and the contents of textbooks affect students' learning directly. So, this study analyzed the achievement standards of the curriculum and formula types and situations, and the introduction process of non-standard and standard algorithms presented in Korean mathematics textbooks. The results are follows: there was little difference in the achievement standards of the curriculum, but there was a difference in the arrangement of contents by grades in textbooks. There was a difference in the types of formula according to textbooks. And the situation became more diverse; recent textbooks have changed to the direction of using the non-standard and the standard algorithm in parallel. In conclusion, I proposed categorizing rather than splitting the types of fraction division, the connection of non-standard and standard algorithm, and the need to prepare methods to pursue generalization and justification according to the common characteristics in the process of introducing standard algorithm.

This study aims to get an implication on elementary pre-service teacher education by exploring how the noticing of pre-service teacher changes within a learning community. In this study, a learning community consisting of a elementary pre-service teacher and researchers was formed to plan and conduct actual classes and to reflect teaching strategies. Voice and video data on actual classes and learning community activities, reflective journals and post-interviews of the elementary pre-service teacher, field notes of the researcher, and students’ outcomes were collected. The characteristics of elementary pre-service teachers' noticing were analyzed in three stages: attending, interpreting, and deciding how to respond. The results are as follows. First, the pre-service teacher’s attending moved from the result of task to student’s statistical thinking. Second, the pre-service teacher’s interpreting changed from a lack of diversity and specificity of evidence to diversity and specificity. Third, pre-service teacher’s deciding changed from unproductive deciding to productive deciding.
