Teachers' personal knowledge (PK) is an element in their pedagogic-practical knowledge. This study exposes the PK of primary school mathematics teachers regarding solid geometry through reflection. Students are exposed to solid geometry on various levels, from kindergarten age and above. Previous studies attested to the fact that students encounter difficulties-strong dislike and fear engendered by geometry. A good number of teachers have strong dislike to solid geometry, as well. Therefore, those engaged in teaching the subject must address the problem and try to overcome these difficulties. In this paper we have introduced the reflective process among teachers in primary school, including application of Van-Hiele's theory to solid geometry.

The purpose of this article was to clarify the meaning of constructivist teaching and to improve methods related to constructivist teaching. As a theory of learning, constructivism is serving as the basis for many of the current reforms in education. Many educators, however, misconceive what constructivist teaching means. The application of Piagetian theory to early childhood education was reviewed and analyzed. This article provides the overarching principles of constructivist teaching in early childhood classrooms with emphasis on illumination of the misconception. It postulates that constructivist teachers find their own autonomously selected ways to integrate the principles of constructivist teaching.

Piaget's revolutionary study on the cognitive development of children has focused on the development of logic. Logical operations and a variety of classifications based on the set of accepted rules involve convergent thinking. Children and adults have logical and creative thinking which deal with a reality of thinking. This study aims to examine a cognitive structure of students, which is closely related to the Piaget's cognitive development theories of students when creative thinking. Students were given an open mathematical problem and were expected to be able to take advantage of sensitivity, fluency, flexibility, originality, and elaboration which can be seen as clearly of their structure cognitive.

The purpose of this study is to create an interactive tool Geometry Player for geometric explorations. In designing this software, we referred to van Hiele's geometric learning theory of and Duval's cognitive comprehension theory of geometric figures. With Geometry Player, it is easy to construct and manipulate dynamic geometric figures. Teachers can easily present the dynamic process of geometric figures in class, and students can use it as a leaning tool to construct geometric concepts by themselves. It is hoped that Geometry Player can be a useful assistant for teachers and a nice partner for students. A brief introduction to Geometry Player and some application examples are included in this paper.

코로나19가 전세계를 휩쓸고 있고, 이로 인해 정치, 경제, 문화 등 모든 면에서 위기를 겪고 있다. 코로나19의 시작과 확산, 주춤과 재확산 등을 경험하면서 국민들은 불안감과 우울감 속에 힘들게 살고 있다. 코로나19 위기를 말미암아 한국교회는 현장예배를 드리기가 힘들어 온라인예배가 시작되었고, 현장예배가 시작된 교회도 온라인예배를 병행하고 있다. 교회학교의 경우에는 교제와 교육의 기능이 마비되었고, 대부분 온라인예배에 비중을 두며 주일예배만 어렵게 드리고 있는 형편이다. 코로나19 이전의 모습으로 돌아가기를 간절히 원하지만, 코로노19가 전 세계 이슈, 팬데믹 상황이 되었기에 쉽지 않아 보인다. 이러한 가운데 상황이 나아지기만을 가만히 기다릴 수 없다. 2020년 3월에는 4월이 되면 나아지겠지, 4월에는 5월이 되면 나아지겠지, 5월에는 6월이 되면 나아지겠지, 6월에는 7월이 되면 나아지겠지 라는 막연한 기대를 가지고 지금까지 지나왔다. 그러는 사이 교회는 교회 본연의 사역을 제대로 감당하지 못했고, 교육의 사명을 온전히 감당하지 못했다. 많은 교회의 대처는 2020년 상반기에 계획해 놓은 사역을 하반기에 연기한 것 정도이다. 이제 코로나19 상황이 나아지는 것을 기대하고, 상황이 나아지면 그 이전에 계획하고 준비한 것을 하려는 시도에서 벗어나서, 새로운 방향을 설정하고 새로운 방향으로 나아가기 위해서 구체적으로 준비해야 한다. 이러한 관점을 가지고 본 논문은 코로나19 시기 이후의 기독교교육 방향에 대해 연구하였다. 구체적으로 코로나19 시기 이후의 기독교교육 방향의 이론적 기반을 아가페적 만남의 이론, 카테키시스 이론, 디아코니아 이론에서 찾았고 이 이론에 따라 구체적인 방향을 제시했다. 구체적으로 아가페적 만남의 이론에 근거해서 자연환경과의 만남을 강조하는 기독교교육, 가족 구성원 간의 만남을 강조하는 기독교교육, 세계 시민 간의 만남을 강조하는 기독교교육, 온라인을 통한 만남을 중시하는 기독교교육을 제시했다. 그리고 카테키시스 이론에 근거해서 이단의 공격에 대응하는 기독교교육을 제시했고, 마지막으로 디아코니아 이론에 근거해서 사회를 위한 봉사와 섬김의 기독교교육과 데이터를 기반으로 한 섬김의 기독교교육을 제시했다.

This study investigated preservice teachers' perceived constraints in implementing their ideal pedagogies and the influence of the teacher education program on their pedagogical beliefs changes. Unique features that the university-based coursework and field experiences had on preservice teachers' learning to teach were also explored. This preservice teacher education program employs constructivist aspects of teacher education and generates applications of constructivism to the practice of teaching. Major findings include: preservice teachers' having traditional pedagogy as the default, recovery of prior beliefs, constraints on implementing constructivist pedagogy, and being overly confident in themselves as teachers. With the influence of constructivist epistemology, these preservice teachers' pedagogical beliefs evolved and were refined over time as they incorporated various constructivist ideas. The benefits and influences of the M.Ed. program's theoretical coursework and the field experiences on these teachers' learning-to-teach experiences are addressed with rich data. The implications for teacher educators as well as for the instructional practices of preservice teacher education programs are discussed. Recommendations for future research are also presented.

This study examined the meanings of reflective utterances fathers regarding their paternal role and the relationship of this to the process of a reflective parent education program for fathers whose children had been referred to psychotherapy. The subjects were 2 fathers aged in their late-thirties of 2 children with emotional behavioral problems. The father education program consisted of contents based on object relation theory. The reflective dialogues between fathers and the parent educator in the process of the program were analyzed. The meanings of the reflective utterances made by the fathers were indicated to be the understanding of the relationship between child's problematic behaviors and family dynamics, a reflection on their oppressive child rearing behaviors, the awareness of the necessity for emotional exchange with family members, the importance of cooperation between both the mother and father when it comes to child rearing, and the values at the heart of being together with children. The implications of the results were also discussed.

In modern theory, creativity is an aim of mathematics education not only for the gifted but also fur the general students. The assertion that we must cultivate the creativity for the gifted students and drill the mechanical activity for the general students are unreasonable. Freudenthal has advocated the reinvention method, a pedagogical principle in mathematics education, which would promote the creativity. In this method, the pupils start with a meaningful context, not ready-made concepts, and invent informative method through which he could arrive at the formative concepts progressively. In many face the reinvention method is contrary to the traditional method. In traditional method, which was named as 'concretization method' by Freudenthal, the pupils start with ready-made concepts, and applicate this concepts to various instances through which he could arrive at the understanding progressively. Freudenthal believed that the mathematical creativity could not be cultivated through the concretization method in which the teacher transmit a ready-made concept to the pupils. In the article, we close examined the reinvention method, and presented a context of delivery route which is a illustration of reinvention method. Through that context, the principle of pascal's triangle is reinvented progressively.

As reliance on information and communication becomes widespread, a variety of information dysfunctions such as hacking, viruses, and the infringement of personal information are also occurring. Korean adolescents are especially exposed to an environment in which they are experiencing information dysfunction. In addition, youth cybercrimes are steadily occurring. To prevent cybercrime and the damage caused by information dysfunction, information security practices are essential. Accordingly, the purpose of this study is to discuss the factors affecting the information security practices of Korean youths, considering information security education, perceived severity, and perceived vulnerability as leading factors of the theory of planned behavior. A questionnaire survey was administered to 118 middle and high school students. Results of the hypothesis test show that information security education affects perceived behavior control, and perceived severity affects attitude. Subjective norms, information security attitudes, and perceived behavioral control were found to influence adolescents' practices of information security. However, perceived vulnerabilities did not affect youths' information security attitudes. This study confirms that information security education can help youths to practice information security. In other words, information security education is important, and it is a necessary element in the information curriculum of contemporary youth. However, perceived vulnerability to youth information security threats did not affect information security attitudes. Consequently, we suggest that it is necessary to strengthen the contents of the information security education for Korean youths.
