The purpose of this study is to develop instructional methods for the formalized algorithm through informal knowledge in teaching division of fractions. The following results have been drawn from this study: First, before students learn formal knowledge about division of fractions, they knowledge or strategies to solve problems such as direct modeling strategies, languages to reason mathematically, and using operational expressions. Second, students could solve problems using informal knowledge which is based on partitioning. But they could not solve problems as the numbers involved in problems became complex. In the beginning, they could not reinvent invert-and-multiply rule only by concrete models. However, with the researcher's guidance, they can understand the meaning of a reciprocal number by using concrete models. Moreover, they had an ability to apply the pattern of solving problems when dividend is 1 into division problems of fractions when dividend is fraction. Third, instructional activities were developed by using the results of the teaching experiment performed in the second research step. They consist of student's worksheets and teachers' guides. In conclusion, formalizing students' informal knowledge can make students understand formal knowledge meaningfully and it has a potential that promote mathematical thinking. The teaching-learning activities developed in this study can be an example to help teachers formalize students' informal knowledge.

Teachers are facing various job demands with psychosocial aspects being fundamental due to the nature of the occupation. Although teachers' work is associated with different psychosocial health risks, little is known on how to identify and tackle those. Thus, a systematic literature search as per the PRISMA statement was conducted via MEDLINE (PubMed), PSYNDEX (PubPsych), and ScienceDirect. Two reviewers independently screened 2261 titles and abstracts and 169 full-texts. According to the inclusion criteria established a priori, articles from peer-reviewed journals (English or German) on psychosocial risk management in teachers were incorporated. Despite a comprehensive and sensitive search, only four publications could be identified, outlining a process to implement risk management and different assessment tools. Taken together, data presented in the articles were scarce. Recommendations for process steps and the assessment of psychosocial risks can be derived from the findings. To implement effective psychosocial risk management in the teaching profession, further research is needed, though. Effective and practicable approaches, which are accepted by the target group, should be further developed and investigated. Relevant causes of occupational strain in the teaching profession must be identified and assessed reliably. Low-threshold interventions should be implemented, and the outcome must be evaluated afterward.

이 연구에서는 DASTT-C(Drawing-A-Science-Teacher-Test Checklist)를 이용하여 국내 초등 예비교사들의 과학 교수에 대한 자기 이미지와 이미지 형성에 영향을 미치는 요인에 대해 조사했다. 3개 교육대학을 선정한 후, 과학 심화전공과 비과학 심화전공의 2학년 학생 182명을 대상으로 1학기 초에, 4학년 학생 183명들을 대상으로 2학기 초에 DASST-C를 실시했다. 연구 결과, 과학 심화전공의 경우 2학년 보다 4학년 학생들의 과학 교수에 대한 자기 이미지가 더 학생 중심에 가까웠다. 그러나 비과학 심화전공의 경우에는 2학년과 4학년 학생들의 DASTT-C 점수 차이가 전체 및 모든 하위 영역에서 통계적으로 유의미하지 않았다. 과학 교수에 대한 자기 이미지에 영향을 미치는 주요 요인으로 심화전공과 관계없이 2학년 학생들은 초 중등 교육과정에서의 교수 학습 경험을 제시했으나, 4학년 학생들의 경우에는 과학교육 관련 과목의 내용이나 교수 방식, 교육실습에서의 실제 수업이나 참관 경험 등을 제시했다. 이에 대한 교육적 함의를 논의했다.

This study explored teachers (n = 219) from northern, central, southern and eastern Taiwan concerning their views about children's learning difficulties, mathematical instruction and school mathematics curricular. Results showed that teachers' mathematics knowledge or their instruction methods had no significant influence on their views of children's learning difficulties. Even though teachers indicated that understanding of abstract mathematical concepts was the most prominent difficulty for children, they tended to employ direct instruction rather than constructive and cooperative problem solving in their teaching. However, teachers' views of children's learning difficulties did influence their instructional practice. Results from in-dept interviews revealed that there were some obstacles that prevented teachers from putting constructiveism perspectives of instruction into teaching practice. Further investigation is needed to develop a better understanding of epistemology and teaming psychology as well as to help teachers create constructive learning situations.
