The purpose of this study was to analyze mathematical errors and the effects of reflective problem posing activities on students' mathematical problem solving abilities and attitudes toward mathematics. We chose two 5th grade groups (experimental and control groups) to conduct this research. From the results of this study, we obtained the following conclusions. First, reflective problem posing activities are effective in improving students' problem solving abilities. Students could use extended capability of selecting a condition to address the problem to others in the activities. Second, reflective problem posing activities can improve students' mathematical willpower and promotes reflective thinking. Reflective problem posing activities were conducted before and after the six areas of mathematics. Also, we examined students' mathematical attitudes of both the experimental group and the control group about self-confidence, flexibility, willpower, curiosity, mathematical reflection, and mathematical value. In the reflective problem posing group, students showed self check on their problems solving activities and participated in mathematical discussions to communicate with others while participating mathematical problem posing activities. We suggested that reflective problem posing activities should be included in the development of mathematics curriculum and textbooks.

The goal of this research was to study the effects of the Mathematical Problem Generating Program on problem solving ability and learning attitude. The experiment was carried out between two classes. One class was applied with the experimental program (treatment group), and the other continued with normal teaching and learning methods (comparative group). In this study, two 5th grade elementary classes participated in Seoul city. In this study, the students were tested their problem solving abilities by the IPSP test and learning attitude by the Korean Education Development Institute (KEDI) before and after use of the program. The collected results were t-tested to find any meaningful changes. The results showed the followings. First, use of the mathematical generating program showed meaningful progressive results in problem solving ability. Second, the students that used the program showed positive results in learning attitude. In conclusion, learning mathematics using the problem generating method helps students deeper understand and solve complex problems. In addition, problem solving abilities can be improved and the attitude towards mathematics can be changed while students are using an active and positive approach in problem solving processes.

무릇 남들 보기에 좋은 것 혹은 남들이 그럴듯하게 인정해주는 것을 하는 것은 진정한 재미와 관계가 없다. 진정한 재미는 스스로 혼자 해도 힘들지 않고, 시간가는 줄 모르고 할 수 있는 일 속에서 찾아온다. 그것이 특정 음식 맛보기 좋고, 음식 만들기여도 좋다. 모형 자동차 조립도 좋고, 오토바이 타기도 좋다. 일단 자신이 좋아하는 것의 리스트가 작성되면 다음 순서로 '동호회'에 가입할 것을 권한다

강건한 벤처산업을 만들기 위해‘위대한 스승’은 꼭 필요하다. 짧은 역사를 가진 한국의 벤처역사속에서도 스승으로 삼을 만한 선배들의 족적들을 심심치 않게 찾아볼 수 있다. 그러나 혜성처럼 빛나다 어느날 사라져 버리는 벤처의 성공신화는 우리시대 스승의 참모습이 아니다. 성공신화만으로는 스승의 참모습으로 부족하다. 왜냐하면 하나의 기업으로서 사회적 책임을 다하는 시대정신을 가져야하고, 또한 장수해야하는‘위대성’을 스스로 보여주어야 하기 때문이다.

학생의 '수학적 힘의 신장'에 기본방향을 둔 제7차 수학과교육과정에선 수행평가를 강조하고 있지만 현재의 수행평가 도구만으로는 학생들의 전인전인 면을 모두 평가하기에는 부족하다. 따라서 본 연구는 수행평가 도구 개발 및 수정 ${\cdot}$ 보안에 초점을 두었다. 첫째, 교사의 '체크리스트'로 학생들의 수업시간중의 행동을 관찰하여 평가하게 하였다. 둘째, '모르는 문제'로 이것은 학생들이 학습하고 나서 모르는 문제를 스스로 선택하여 풀어보고, 해결책을 찾은 다음 알게 된 점을 적게 함으로써 학생들의 자기 주도적 학습을 평가하는 방법이다. 셋째, '문제 만들기'를 통해 학생이 학습한 내용을 통해 스스로 문제를 만들어 보게 하였다. 위에서 제시한 내용을 토대로 교사들이 학교현실과 학생들의 능력 등을 고려하여 수정 ${\cdot}$ 보안한다면 학생들의 전인적인 면을 평가하는데 좋은 평가 방법이 될 것이다.

지난 번 모바일 핫토크를 통해 다양한 모양의 휴대폰 디자인에 대해서 이야기한 바 있다. 이번에는 단말기 제조사에서 제품 제작부터 설계된 디자인에 대한 이야기가 아니라, 제품 구매 후 사용자들이 스스로 꾸미게 되는 액세서리에 대한 부분을 이야기하려고 한다. 사용자들은 휴대폰의 기능을 좀 더 편하게 하기 위해서, 혹은 개성만점의 휴대폰을 만들기 위해서 액세서리를 사용한다. 제조사에서는 간단한 휴대폰 줄과 이어폰 등이 있긴 하지만, 좀 더 색다르고 독특한 컨셉의 액세서리들을 모아서 소개해본다.

The internship is essential for the music therapy curriculum and affords interns the opportunity to apply their classroom-based knowledge and skills to real-world clinical settings. However, challenges associated with the internship can result in interns undergoing trial-and-error learning, interpersonal conflicts, and intrapersonal difficulties. An experiential music therapy group may be useful in helping interns process these incidents and develop their personal and professional skills. We explored the experiences of music therapy interns participating in therapeutic song writing. In this study, five music interns completed two 4-hour sessions of therapeutic song writing. Following the second session, a group interview was conducted with participants to gather data on their experiences. The interview was recorded, transcribed, and analyzed. Six themes and 18 sub-themes were derived from the data. The six themes were preconceptions of therapeutic song writing, meaningful lyric creation, challenges in song composition, structured experiences during song writing process, development of self-awareness through music, and relational experiences resulting from the group process. Participants were able to incorporate their individual internship experiences into a single song by communicating with group members during the step-by-step process. Participation in therapeutic song writing was found to help music therapy interns identify and process challenges encountered during their internship and further their personal and professional development.

Advancements in digital technology have caused significant changes to the tradition of creative educational activities. Such an with digital technology is prone to an error where digital technology itself becomes the goal, ignoring educational efficacy grounded on improved user experience and immersion. Previously, picture book-making activities for children allow them to actively participate in the process of book-making, and is often employed to instill reading habits as well as nurture linguistic abilities. Aside from such picture book-making activities, diverse efforts are being made for innovation in educational pedagogy through digital technology. However, as the goal of children's picture book-making activities is realizing creative education through expressions in language and pictures, digital technology should be considered in the viewpoint of fusion, not as a simple replacement to the traditional tools employed in children's picture book-making activities. This study examines previous researches related to children's picture book-making activities to propose contents and methodology allowing effective immersion by fusing digital technology based on a physical environment, from the viewpoint of fusion and integration. Expect this study will become a fundamental data in visualizing a practical integration of digital technology in future creative education.

The purpose of this study to analysis of problem posing in 5th and 6th grade mathematics textbooks and to comprehend errors in the problem posing activity of 6th graders in elementary school. For solving the research problems, problem posing contents were extracted from mathematics textbooks and practice books for the 5th and 6th grade of elementary school in the 2007 revised national curriculum, and they were analyzed, according to each grade, domain and type. Based on the analysis results, 10 problem posing questions which were extracted and developed, were modified and supplemented through a pre-examination, and a questionnaire that problem posing questions are evenly distributed, according to each grade, domain and type, was produced. This examination was conducted with 129 6th graders, and types of error in problem posing were analyzed using collected data. The implications from the research results are as follows. First, it was found that there was a big numerical difference of problem posing questions in the 5th and 6th grade, and problem posing questions weren't properly suggested in even some domains and types, because the serious concentration in each grade, type and domain. Therefore, textbooks to be developed in the future would need to suggest more various and systematic of problem posing teaching learning activity for each domain and type. Second, the 'error resulting from the lack of information' occurred the most in the problems that 6th graders posed, followed by the 'error in the understanding of problems', 'technical errors', 'logical errors' and 'others'. This implies that a majority of students missed conditions necessary for problem solving, because they have been used to finding answers to given questions only. For such reason, there should be an environment in which students can pose problems by themselves, breaking from the way of learning to only solve given problems.
