According to Krutetskii, the education of mathematically gifted students must be focused on the improvement of creative mathematical ability and the mathematically gifted students need to experience the research process like mathematician. Independent study is highly encouraged as the self-directed activity of highest level in the learning process which is similar to research process used by experts. We conducted independent study as a viable differentiation technique for gifted middle school students in the 3rd grade, which participated in mentorship program for 10 months. Based on the data through the research process, interview with a study participant and his parents, and his blog, we analyzed mathematical behavior characteristics of a study participant. This behavior characteristics are not found in all mathematically gifted students. But through this case study, we understand mathematically gifted students better and furthermore obtain the message for the selection and education of the mathematically gifted students and for the effective method of running mentorship program particularly.

We analyzed the responses of 152 science-gifted high school students by surveying the status and recognition of writing and keeping laboratory notebooks to develop guidelines and education plans. Science-gifted students did not write laboratory notes diligently, despite recognizing that it is crucial to do so. Mentors also tended not to provide faithful guidance and inspection. There was an insufficient practice in using research evidence in laboratory notebooks, such as including names and dates for authentication. In addition, while a high ratio of students owned their own laboratory notebooks, there was not a high level of recognition regarding the retention period, ownership, and responsibility. Based on these results, we propose suggestions for improving educational institutions for gifted students in science. First, it is necessary to strengthen the guidance for science-gifted students to faithfully write laboratory notebooks. Second, education on writing laboratory notebooks should be provided. Third, science-gifted high schools should prepare regulations for the management of lab notes and conduct education based on them.

The purpose of this study is to investigate gifted students in elementary mathematics how they understand of situations involving multiplication and concepts of multiplication. For this purpose, first, this study analyzed the teacher's guidebooks about introducing the concept of multiplication in elementary school. Second, we analyzed multiplication problems that gifted students posed. Third, we interviewed gifted students to research how they understand the concepts of multiplication. The result of this study can be summarized as follows: First, the concept of multiplication was introduced by repeated addition and times idea in elementary school. Since the 2007 revised curriculum, it was introduced based on times idea. Second, gifted students mainly posed situations of repeated addition. Also many gifted students understand the multiplication as only repeated addition and have poor understanding about times idea and pairs set.

This essay aims to seek an alternative model of catechesis, as this form of education faces various challenges from the Korean Church especially during COVID-19 pandemic. For a long time, catechesis in the Korean Church narrowly focused on the act of producing Christians who would be loyal to the local church, rather than focusing on nurturing members loyal to Christ, an issue that has been problematized in recent publications on catechesis. Thus, the loss of social trust in the Korean Church and the decline of its public image exemplify how this type of catechesis as disciple-making for local church's benefit, mostly nurtures a vertical dimension of faith. The current teaching and learning method mostly employs a unilateral transfer of doctrine from the teacher to the learner and emphasizes the memorization of doctrine. This type of instruction renders the catechesis as the most lackluster and outdated form of Christian education. This essay aims to reconceptualize the traditional model of catechesis. This essay first critically evaluates current situations of catechesis and presents several alternative meanings on the concept of doctrine. Then it explores the theories of catechesis through different models posed by Christian educators such as John Westerhoff III and Richard Osmer. The final section is devoted to presenting an alternative form of catechesis that focuses on seeking holistic faith.

Purpose of study: The purpose of this essay is to seek an alternative direction for confirmation education within the context of Korean Protestant Church, addressing the following issues: 1) Confusion in the use of terminology on confirmation, 2) Superficial understanding of confirmation, and the absence or privatization of confirmation theology, 3) Formalized confirmation education based on the concept of rites of passage, and 4) The absence of denominationally structured confirmation education. Research content and method: To achieve this purpose, this essay attempts to foster an intradisciplinary and interactive dialogue on confirmation through a biblical, historical, and theological approach. Biblically, confirmation is to be understood as the unity of the baptism of water and the baptism of Holy Spirit, associated with the consecration of the baptized as royal priests through the baptism of Holy Spirit. Historically, as a part of the rite of Christian initiation, confirmation was a unified rite that has undergone a process of separation and reunification. Theologically, the rite of confirmation affirms the covenant of the Triune God given in baptism and is positioned between baptism and the Lord's Supper. Conclusions and Suggestions: In conclusion, this essay suggests an alternative form of Confirmation education that is oriented towards the following objectives: 1) Education that forms the identity given in the baptismal covenant, 2) Education that reflects characteristics of both baptism and the Lord's Supper, 3) Education that integrates the Bible, doctrine, and life of confirmand and, 4) Education based on an organic educational system.

Many people are suffering from the economic crisis and poverty that are deepening due to the recent spread of the COVID-19 epidemic. In this situation, this study focuses on the biblical Jubilee in order to seek how "Jubilee justice" can be realized in the modern context. The Law of Jubilee consists of four contents: the liberation of slaves, debt remission, land return and fallow. Ultimately it aims to prevent human slavery and preserve equality. Nevertheless, the thought of Jubilee has been distorted theologically and situationally, and as a result, it has been overlooked in the field of Christian education, and there is a limit in Christian practice for social justice. The thought of Jubilee, however, can be an alternative to overcome various problems of modern society such as the issue of the privatization of Christianity or the deepening of polarization caused by neoliberal globalization and can contribute positively to the practice of social justice. In other words, the thought of Jubilee can act as a biblical initiative in reforming wrong laws and establishing institutions for the poor on the institutional level; on the personal level, it can be a great motive in terms of the change of perception and the practice of the sharing economy. Jubilee education, which aims for Jubilee justice, helps to break the misconceptions and change the existing meaning perspectives on the basis of various interdisciplinary knowledge and supports social behavior for transforming social structure through activation of public opinion and fund raising at the practical level. Therefore, the learners of Christian education can play a public role in transforming the unjust society.
