This study examines the educational meaning of the sum of the angles of a triangle in elementary school mathematics and discusses the introduction and explanation methods to convey the meaning faithfully. First, we investigated how to introduce the sum of the angles of a triangle in the Korean national mathematics curriculums from the past to the present and surveyed the experiences and opinions of the teachers. The results of the survey are summarized and discussed in three parts: The context of 'arranging angles activities' and 'measuring angles activities', the methods to convey the meaning of the sum of the angles of a triangle as an invariance, and other details.

Purpose: The purpose of this paper was to develop a CD program of applied logotherapy to improve the quality of life of adolescents with terminal cancer. Method: Keller's ARCS theory and a model for developing internet learning materials(Kang) was applied to develop this program comprised four distinct phases: planning, designing, development, and execution stages. Results: This program was entitled 'Finding treasures in my life' and consisted of 5 sessions and its educational contents were made up as follows: "Treasure One" is 'learning three natures of the human mind', "Treasure Two" is 'learning creative value as first method to find meaning of life', "Treasure Three" is 'learning experiential value as second method to find meaning of life', "Treasure Four" is 'learning attitudinal value as third method to find meaning of life', and "Treasure Five" is 'Becoming the master of my life'. The sub-menu was made up of 'Beginning', 'What is it?', 'Travelling'. 'Laughing Song', 'End'. Conclusions: This CD program applied logotherapy with flash animation technique as an emotional and spiritual nursing intervention program for easier and more scientific application in pediatric oncology and hospice area.

This treatise makes clear not only a structural methodology of 'the conceptual blending theory' using in a linguistics could be applied to the similar process in a hybrid design but also both methods include the same meaning construction in the sense of a mutual educational system. Both methods have something in common that they are fundamentally focused on a metaphorical expression which implies poetic messages to be concentrated on a formal structure. Therefore, the purpose of this treatise is to examine the structural characteristics in the hybrid design in order to analyze the rhetorical expressions(metaphor, allegory) as symbols of communication. One of the those is intertextuality that expresses metaphorically by blending and borrowing codes and another is hypertextual space where various texts twines around each other making brand-new and diverse organizations, as the combined allegory with a number of hidden expression. Ultimately, it is important that this approach could verify whether it deals the illogical present state of a spacial form or structure with a kind of mechanism of a 'conceptual blending theory' or not.

In this research, we designed a teacher professional development (PD) program where a small group of mathematics teachers could share, reflect on, and discuss their pedagogical knowledge and practices of ICT-integrated lessons, using a video annotation tool called DIVER. The main purposes of this paper are both micro and macro: to examine how the teachers were engaged in the meaning-making process in a video-based PD (micro); and to derive implications about how to design effective video-based teacher PD programs toward a teacher community of practices (macro). To examine teachers' meaning-making in the PD sessions, discourse data from a series of 10 meetings was segmented into idea units and coded to identify discourse patterns, focusing on (a) participation levels, (b) conversation topics, and (c) conversation depth. Regarding the affordance of DIVER, discourse patterns of two meetings, before and after individual annotation with DIVER were compared through qualitative vignette analysis. Overall, we found that the teacher discourse shifted the focus from surface features to deeper pedagogical issues as the PD sessions progressed. In particular, the annotation function in DIVER afforded the teachers to exercise descriptive analyses of video clips in a flexible manner, thereby helping them cognitively prepared to take interpretative and evaluative stances in face-to-face discussions with colleagues. In conclusion, deriving from our research experiences, we discuss the possibilities and challenges of designing video-based teacher PD in a school context.

Alternative education in Korea has grown into an educational movement since the 1990s. The alternative education is affecting and growing the public education system such as innovative schools, free semester systems, and high school credit systems. In 2021, an institutional foundation was also established to be recognized and supported as an educational institution. As a result of reflecting on the alternative education movement for 20 years, it is understood as stagnant lost time in the second half of the decade. It is discussing reorganizing the meaning of future-oriented "alternatives" with the new "alternatives". The poverty of educational philosophy has also been highlighted as an issue, but no special discussions have been underway. Thus, the study discussed to propose an educational philosophy that could capture the ideologies of alternative education. Critical pedagogy aims to foster human beings who are subjective, autonomous, active and self-reliant through conscious emancipation. In recent years, critical pedagogy have discussed ecological environment and feminism. The educational philosophy of scholars such as Freire and Illich was the basis of the early alternative educational movement. Considering this, the study discusses that Korea's alternative education movement can be understood through critical education and is reasonable as an educational philosophy for new alternatives in the future.

The purpose of this study is to examine how the opportunities of close emotional support and communication provided by child-teacher dialogue journal writing activities are meaningful to the three subjects of early childhood education, children, teacher, and parents, and provide implications about how to utilize child-teacher dialogue journal writing activities in the field of education properly. According to the findings, first, to children, child-teacher dialogue journal writing activities are meaningful as asecret time between them and their teacher, time that their teacher pays keen attention to them, and time to enhance confidence. Second, to teachers, child-teacher dialogue journal writing activities are meaningful as aspecial time to be with children, time to understand children, and time to reflect on their educational process and figure out proper teaching or supporting methods. Third, to parents, child-teacher dialogue journal writing activities are meaningful in a way in which they can understand moreabout their children and is a meaningful time to plan and provide proper care upon their children's wishes or needs.

This study analyzes the epistemological meaning of‘social construction’in mathematical instruction. The perspective that consider the cognition of mathematical concept as a social construction is explained by a cyclic scheme of an academic context and a school context. Both of the contexts require a public procedure, social conversation. However, there is a considerable difference that in the academic context it is Lakatos' ‘logic of mathematical discovery’In the school context, it is Vygotsky's‘instructional and learning interaction’. In the situation of mathematics education, the‘society’which has an influence on learner's cognition does not only mean‘collective members’, but‘form of life’which is constituted by the activity with purposes, language, discourse, etc. Teachers have to play a central role that guide and coordinate the educational process involving interactions with learners in this context. We can get useful suggestions to mathematics education through this consideration of the social contexts and levels to form didactical situations of mathematics.

This study aims to investigate the representation patterns used by elementary teachers and their meaning-making process in electromagnetic experiments. In particular, we analyzed the representations depending on three levels of their abstractness: enactive representation (action based), iconic representation (image based) and symbolic representation (language based). For this, four experiment activities of two teachers were analyzed and the results are as follows. First, as an overall pattern of representation, an experiment subject is presented as the form of symbolic representation and the related concepts, experimental materials and methods are embodied through iconic representation. Then, through enactive representation, the actual experiments are implemented. The experimental results are primarily recorded through iconic representations and abstracted into symbolic representations to draw conclusions. The different levels of representations complement each other to expand their meanings, however, sometimes they also make inconsistent meanings among different levels. Based on these results, educational implications were discussed in terms of supporting and improving electromagnetic experiment activities.

Korean proverbs concerning parent child relationships were collected from literature. 95 proverbs were selected for this study. The proverbs were categorized by meaning; value of child, affection toward child, boy-preference, positive-negative affection coward daughter, importance of child's education, child-rearing stress, identification of parent, authoritative control, and filial piety. The subjects (223 married men and 224 married women) were asked to indicate their understanding of the meaning of the proverbs. The degree of agreement was analyzed. The results revealed variability in their understanding and the high degree of agreement on the proverbs. Demographic variables, age, educational level, and religion, appeared to be the important factors in the subjects' agreement.
