Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Jang Sin-Ae , Song Young-Soo
Published: August 2024

Objectives The purpose of this study was to verify the mediating effect of job crafting and the moderated mediating effect of five personality factors in the relationship between empowering leadership and job enthusiasm of large airline and low-cost airline flight attendants, and to compare the differences between the two groups.
Methods For this purpose, data were collected using an online questionnaire (Naver Questionnaire) targeting 540 flight attendants of large domestic airlines and low-cost airlines. The questionnaire included measures such as empowering leadership, job crafting, job enthusiasm, and personality 5 factors. The collected data were analyzed for frequency analysis, descriptive statistical analysis, reliability analysis, correlation analysis, mediation effect, moderation effect, and moderated mediation effect using the SPSS 26.0 program and the SPSS Process Macro program.
Results As a result of the analysis, first, empowering leadership perceived by airline flight attendants was found to have an effect on job crafting. Second, empowering leadership and job crafting perceived by airline flight attendants were found to have an effect on job enthusiasm. Third, job crafting was found to play a mediating role in the relationship between empowering leadership and job enthusiasm. Fourth, in the relationship between empowering leadership and job enthusiasm perceived by large airline flight attendants, conscientiousness was found to have a moderated mediating effect among the five personality factors through job crafting. In addition, in the relationship between empowering leadership and job enthusiasm perceived by low-cost airline flight attendants, openness was found to have a moderated mediating effect among the five personality factors through job crafting. On the other hand, the results showed that extraversion and neuroticism had no moderating effect in the relationship between job crafting and job enthusiasm.
Conclusions These research results can be used as useful data to design training and programs tailored to each organizational culture and goals based on the personality factors of future aviation flight attendants. In addition, it is deemed necessary to conduct research on the effects of empowering leadership and job crafting on job enthusiasm and innovative behavior.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Lee Meeyeon , Lee Gowoon
Published: August 2024

Objectives The purpose of this study is to analyze the frequency of brass audition pieces for the admission of the music colleges over the past five years, from 2020 to 2024, and to explore the educational implications for students.
Methods To this end, we analyze the frequency of brass audition pieces at universities such as Kyung Hee University, Seoul National University, Yonsei University, Ewha Womans University, Korea National University of Arts, and Hanyang University, which are universities that designate audition pieces.
Results First, the repertoire for brass instrument audition is very limited. Second, the audition pieces do not include enough etudes that can identify the student's basic performance qualities. Third, there are almost no examples of sight-reading exercises for evaluating transposition ability. Fourth, the prevalence of free-choice piece selection in university admissions restricts the enhancement of students' musical abilities for preparation.
Conclusions The presentation of audition pieces for selection of college brass instrument majors must include various elements. This is because a limited repertoire of audition pieces may limit students' opportunities for diverse musical experiences, and may lead to a tendency to practice only the pieces absolutely necessary to be accepted to a target university with good grades. Therefore, a wide range of works from various genres, eras, and composers should be included in the test, and certain criteria for admission should be established, such as an etude test and a limited selection of free-choice pieces to maintain certain audition standards.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Lee Dosik , Jang Hyungshim
Published: August 2024

Objectives This study aimed to test the mediating effect of self-esteem on the effect of employment status on depression in middle-aged adults.
Methods The data of 4,942 people from the 17th year (2022) of the Korean Welfare Panel Study (KOWEPS) were used for the analysis. Statistical analysis was conducted using SPSS 25.0 for reliability analysis and correlation analysis, and Baron and Kenny's three-step regression analysis and Sobel test were used to confirm the mediating effect of self-esteem.
Results First, employment status had a significant positive effect on self-esteem (β=.174, p<.001), and second, employment status had a significant negative effect on depression (β=-.104, p<.001). Third, we analyzed whether self-esteem mediates the relationship between employment status and depression using a three-stage hierarchical regression analysis, and in the third stage, with depression as the dependent variable, employment status (β=-.028) and self-esteem (β=-.413, p<.001) were found to be fully mediated, and significance (Z=-11.217, p<.05) was confirmed using the Sobel test.
Conclusions It was confirmed that midlife employment status has a significant effect on depression through the mediation of self-esteem. This study provides theoretical evidence and practical implications for the development and application of reemployment education for retirees, retirees, the unemployed, and those seeking to reenter the workforce, not only focusing on employment rate and productivity, but also increasing the value of psychological programs that can effectively prepare for the second stage of life in midlife.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Park Kyungmee , Kim Hwa Kyung
Published: August 2024

Objectives By comparing and analyzing the scores of each mathematics content domain in TIMSS and PISA, which are representative international comparative studies, we aim to analyze the strengths and weaknesses of Korean students in specific content domains.
Methods We analyzed the average achievement of each country's mathematics content domain. For a more in-depth comparison, we matched Korean students with foreign students who have similar math scores and ESCS (Economic, Social, and Cultural Status Index) using the propensity scoring matching method, and compared their scores in each content domain one-on-one.
Results The analysis of PISA 2022 and TIMSS 2019 showed consistent results across both the average analysis by mathematics domain and the propensity score matching method. Korean students scored higher in geometry compared to other domains, while their performance in probability and statistics was relatively low.
Conclusions The strength of Korean students in geometry may be related to the shift away from rigorous geometry education centered on deductive reasoning towards using various justification beyond proof. The low achievement in probability and statistics is connected to the fact that statistics education remains knowledge-centered and isolated from real-life contexts. There is a need to enhance statistical knowledge through experiences in statistical problem solving, which includes setting problems, collecting, analyzing, and interpreting data.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kwon Kyounglim , Jo Meounggun
Published: August 2024

Objectives We classified latent groups in the usage patterns of private education for elementary school students before and after COVID-19 and explored the transition probability.
Methods For this purpose, the 12th and 13th data from the Korean Children's Panel were used. Latent class analysis and latent transition analysis were used to classify groups and identify the characteristics of each latent group.
Results Each was classified into three latent groups, and each could be classified into a subject-centered group (high group), a math and english centered group (medium group), and a low-participation group (low group), and the transition probability for each was calculated.
Conclusions After the outbreak of COVID-19, the average number of subjects used in private education decreased, but the use of English/mathematics subjects was maintained, and there was a movement toward use in other subjects. And the increase in average household income did not affect the shift to a subject-centered group.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Jung Youngmi , Kwon Jungson
Published: August 2024

Objectives This study was conducted to prepare basic data for teacher education that can help build expertise in physical exercise instruction in the [physical exercise, health] area, which is one of the important areas of early childhood education.
Methods To find out the past exercise experience, current physical condition, and awareness of exercise/health education of pre-service teachers in Korea and Japan, a survey was conducted targeting childhood pre-service teachers attending early childhood teacher training universities in Korea and Japan.
Results First, the exercise preference of prospective teachers in Korea and Japan was generally high in both countries without significant differences. However, the level of past physical exercise participation in childhood (p<.01) and experience of participating in sports during school years (p<.01) were higher in Japan than in Korea. Second, the level of knowledge about body and health among prospective teachers in Korea and Japan was higher in Japan than in Korea, at p<.01. Confidence in physical strength was also higher in Japan than in Korea at p<.01. Third, in terms of awareness of health education according to the presence or absence of knowledge about body and health, the higher the level of knowledge, the higher the awareness of health education (p<.000). Regarding the level of awareness of physical exercise, all participants had a high level of awareness regardless of whether they had knowledge or not. Fourth, in the correlation between exercise preference and physical exercise and health-related items, past exercise experience and preference showed a positive correlation with current exercise participation and awareness of health.
Conclusions Past experiences are related to the formation of current perceptions and attitudes. Therefore, [Physical Exercise and Health]-related education should be implemented more actively in the previous teacher education, which will affect future early childhood teachers' teaching awareness and attitude toward the [Physical Exercise and Health] area.

Epistemologicamente, a estratégia pedagógica, que se constitui de um método investigativo, insere-se em carácter de ensaio, justificando-se coerente com diretrizes pertinentes da literatura em educação científica no contexto da visão mais dominante nos últimos anos, que é a hipotética-dedutiva.
APRENDER COM OS SIGNOS E O ENSINO DE CIÊNCIAS: ALGUMAS PROVOCAÇÕES
Authors: Costa Dhemersson Warly Santos , Brito Maria dos Remédios de
Published: August 2024

Aprender é um problema central no Ensino de Ciências. Não há como negar, porém, que a leitura do aprender em ciências tem passado fortemente pela psicologia da educação, especialmente as cognitivistas que em suas bases reside uma imagem da recognição, aprender como processo voluntário, implicado em uma boa vontade tanto do aluno quanto do professor. Tudo se passa como se existisse uma espécie de modelo a ser seguido, repetido, experimentado, elaborado e memorizado. A favor de uma outra imagem, propõe-se pensar o aprender no ensino de ciências emaranhado pela imprevisibilidade, por um precursor sombrio, inconsciente, por uma trama da ordem da sensibilidade provocada pelo encontro com os signos que arrastam professor, aluno, ensino por vias desafiadoras e inventivas, muito mais do que representativas, plasmadas em práticas meramente empiristas. Indaga-se: O que são os signos? O que seria esse aprender atravessado pelos signos? Que aberturas os signos trazem para os processos de ensinar e aprender ciências? O ensaio é inspirado pela leitura Deleuziana, notadamente atravessado pelas obras Diferença e Repetição e Proust e os signos, além de comentadores, filósofos da educação, preocupados com o problema do aprender. O aprender é muito mais da ordem das intensidades e dos encontros que arrastam o corpo para o desconhecido do que da ordem da clareza e evidências.

CONHECIMENTO PEDAGÓGICO DO CONTEÚDO NO ENSINO DE CIÊNCIAS E MATEMÁTICA: UM PANORAMA BRASILEIRO
Authors: Gasparini Felipe , Bedin Everton , Miranda Eduardo
Published: August 2024

O Conhecimento Pedagógico do Conteúdo (PCK) surgiu como uma teoria que visa analisar as formas de manifestação do conhecimento a partir da prática docente em sala de aula, ao se considerar as experiências prévias e o contexto em que cada sujeito se encontra inserido. Neste artigo, objetiva-se apresentar o panorama do Estado do Conhecimento acerca das pesquisas nos Programas de Pós-Graduação na área do Ensino de Ciências e Matemática sobre o PCK a partir do Banco de Teses e Dissertações da CAPES. Numa abordagem quali-quantitativa, de objetivo exploratório e natureza básica, esta pesquisa identificou aspectos nos estudos sobre PCK à luz da Análise de Conteúdo como tipo e ano de defesa, Programas de Pós-Graduação e orientador e, dentre outros, metodologia e objetivos. Notou-se uma distribuição similar entre teses e dissertações, mas a sub-representação de estudos das regiões Norte, Nordeste e Centro-Oeste indica não haver panorama geral sobre as possibilidades de investigações sobre o PCK no país. Isto também é reforçado pelo predomínio da Química, com perspectivas mais inovadoras, em relação às demais ciências, que tendem a abordagens mais bem estabelecidas. A Análise de Conteúdo sobre os objetivos reforça a importância do PCK para estudos sobre a formação inicial e continuada de professores, bem como a tendência recente de aliar o PCK com outros referenciais teóricos do Ensino de Ciências e Matemática.

Authors: Ramírez Cáceres Kevin Enrique , Pic Élise
Published: August 2024

En Colombia, los programas de apropiación social de la ciencia y tecnología enfrentan un gran desafío intercultural: propiciar diálogos entre las distintas epistemologías que crean conocimientos plurales en un mismo territorio nacional. El Centro de Pensamiento Pluralizar la Paz de la Universidad Nacional de Colombia se propuso explorar esta diversidad de saberes en torno al concepto de paz. Para lograrlo, se eligió investigar la pluralidad de conocimientos, principalmente, a través de diálogos con cosmovisiones, vocabularios y prácticas de algunas comunidades indígenas del país. El proyecto de investigación-creación, denominado Sanaduría, culminó en una exposición museográfica y sirvió como insumo para reflexionar sobre las políticas públicas del Ministerio colombiano de Ciencia, Tecnología e Innovación, que financió la iniciativa. El proceso investigativo, concebido como un laboratorio pedagógico, permitió volver sobre distintos registros de saberes que suelen concebirse de manera discontinua. Este artículo tiene tres objetivos: en primer lugar, identificar y problematizar el conjunto de conceptos que estructuran las políticas científicas colombianas de las últimas décadas; en segundo lugar, confrontar estas políticas con la experiencia concreta de ejecución de un programa de apropiación social de conocimientos interculturales; y, en tercer lugar, ofrecer una serie de recomendaciones de políticas públicas relativas a investigaciones interculturales.

Insights into the human-jaguar Panthera onca (Carnivora: Felidae) interactions in Tortuguero National Park, Costa Rica
Authors: Arroyo-Arce Stephanny , Thomson Ian
Published: August 2024

Introduction: Human-wildlife interactions are on the rise due to anthropogenic pressures. Understanding these interactions is crucial for preventing conflict and promoting coexistence, ultimately benefitting humans and wildlife. Objective: In this study, we analysed the interactions between humans and jaguars Panthera onca in Tortuguero National Park, Costa Rica. Methods: We examined data concerning jaguar sightings within Tortuguero National Park, Costa Rica compiled from 2000 to 2022. Results: A total of 381 jaguar sightings were recorded, of which 75% occurred in the coastal habitat; 81% occurred during the leatherback sea turtle Dermochelys coriacea (March-May) and the green sea turtle Chelonia mydas (June-October) nesting seasons. From photographic records, 26 individual jaguars were identified (14 females, 12 males). Furthermore, 9% of the sightings were reported within the boundaries of Tortuguero village, where at least 48 domestic dogs Canis lupus familiaris were attacked by jaguars. Conclusions: Despite the jaguar's cryptic nature, the data show an increase in the frequency and duration of jaguar sightings over the years. This trend is likely due to an increase in the local jaguar population and possibly an increase in jaguars' tolerance towards humans, possibly triggered by people's inappropriate behaviour (e.g. approaching jaguars while feeding, mating or with their cubs) during the sightings. Our study also highlights the potential for conflict due to jaguar predation of domestic dogs, which is increasing within the study area. Therefore, there is a need for management action to promote coexistence between humans and the local jaguar population in Tortuguero National Park, Costa Rica.

Stiffened Cold-Formed Steel (CFS) sections often exhibit intricate nonlinear behaviors attributable to factors such as flexure effects and excessive slenderness. Traditional design methodologies, including the direct stiffness method, may inadequately capture these subtleties, potentially resulting in conservative or suboptimal designs. This study aimed to evaluate the performance of various machine learning algorithms, including simple and ensemble models, to predict the bending capacity of stiffened and unstiffened cold-formed beams in pure bending. A parametric study was conducted based on verified finite element analysis, and the machine learning algorithms were utilized to develop a unified capacity prediction method. The performance of six classical machine learning algorithms and four ensemble models were compared. The findings demonstrate that ensemble models, including AdaBoost, Gradient Boosting, Random Forest, and Extra Trees, outperform simple machine learning models in predicting the bending capacity of CFS beams. Moreover, introducing the stacking ensemble technique, using six different base models selectively, resulted in better performance than the individual baseline models. The approach addressed the nonlinearity pattern in the dataset caused by the flexure effect and excessive slenderness. The study suggests that adopting the proposed numerical and machine learning techniques could be a reliable method for predicting the structural behaviour and conducting cost-effective design of CFS beams, compared to the traditional analytical methods.

Science education in fourth-grade elementary school is still inclined towards a teacher-centred approach, where students prioritize memorizing theories and concepts. This results in a lack of development in scientific attitudes and students' absorption of the material. This research aims to describe the cultivation of scientific attitudes through the inquiry-based demonstration learning method. The research methodology is qualitative, utilizing data collection through observation, interviews, and documentation at SD Negeri Kedungwaduk 1 in Sragen. The study involves teachers and fourth-grade students as research subjects. The research findings indicate that the cultivation of scientific attitudes using the inquiry-based demonstration method reached 73.46%. Successfully instilled scientific attitudes include: 1) Curiosity at 64%, 2) Response to data/facts at 100%, 3) Critical thinking at 35%, 4) Discovery and creativity at 57%, 5) Open-mindedness and cooperation at 100%, 6) Independence at 71%, and 7) Environmental awareness at 85%. However, further intervention is needed to enhance critical thinking, which is currently at 35%, through exploration, experimentation, discovery, and small-group learning.
