The purpose of this study is to find out what mathematical situation means, how to pose a meaningful situation and how situation-centered teaching could be done. The obtained informations will help learners to improve their math abilities. A survey was done to investigate teachers' perception on teaching-learning in mathematics by elementary teachers. The result showed that students had to find solutions of the textbook problems accurately in the math classes, calculated many problems for the class time and disliked mathematics. We define mathematical situation. It is artificially scene that emphasize the process of learners doing mathematizing from physical world to identical world. When teacher poses and expresses mathematical situation, learners know mathematical concepts through the process of mathematizing in the mathematical situation. Mathematical situation contains many concepts and happens in real life. Learners act with real things or models in the mathematical situation. Mathematical situation can be posed by 5 steps(learners' environment investigation step, mathematical knowledge investigation step, mathematical situation development step, adaption step and reflection step). Situation-centered teaching enhances mathematical connections, arises learners' interest and develops the ability of doing mathematics. Therefore teachers have to reform textbook based on connections of mathematics, other subject and real life, math curriculum, learners' level, learners' experience, learners' interest and so on.

The principal objective of this study was to evaluate the consumption behavior and perceptions of environment-friendly agricultural products(EAPs) by university students in the Chonbuk area, Korea. Self-administered questionnaires were collected from 309 university students(male 33.0%, female 67.0%). Descriptive and comparative statistical analyses was completed using SPSS v. 12.0. The percentage of subjects who purchased EAPs was 70.9%. Of those, 87.2% had EAPs purchased by their mothers. The most purchased EAPs were vegetables, the primary reason for which was the perception of 'good for health'(73.1%). The main information source about EAPs was 'familes/freinds'. The average scores of 'attitude toward EAPs', 'knowledge toward EAPs', 'concern toward EAPs' were $3.76{\pm}0.57$, $2.91{\pm}0.61$ and $3.29{\pm}0.43$, respectively. With regards to 'attitude toward EAPs', the scores were significantly affected by 'self-reported health status'(p<0.05). With regard to 'knowledge toward EAPs' and 'concern toward EAPs', the scores were significantly affected by 'supplements for health' (p<0.05; p<0.001). For university students' right choices of EAPs, information and consumer education wthin the university curriculum on these products are necessary.

Purpose: Korea is one of the most rapidly aging countries, accompanied by an increasing number of older adults with dementia. Certified-care-assistants are the primary care workers for these older adults. This cross-sectional descriptive study compared the factors influencing care behaviors among Korean and non-Korean certified-care-assistants in Korea. Methods: Participants, 113 Korean certified-care-assistants and 71 non-Korean certified-care-assistants, completed a survey questionnaire. The questionnaire was designed to assess dementia knowledge, attitude and care behaviors toward older adults with dementia. To determine the differences in these two groups, t-test was used. A stepwise multiple regression was performed to identify factors related to care behavior. Results: Significant differences in dementia knowledge, attitude and care behavior toward older adults with dementia emerged between Korean and non-Korean certified-care-assistants. Factors influencing care behavior varied by group. Dementia knowledge and education level were the significant factors of care behaviors in Korean certified-care-assistants, whereas attitude toward older adults with dementia was the significant factor in non-Korean certified-care-assistants. Conclusion: Findings indicate that different factors influence the care behavior of two groups. These findings can be utilized to develop certified-care-assistants' training curriculum that needs to be tailored by nationality to improve the quality of care for older adults with dementia.

Education emphasizes problem-solving skills based on convergent thinking power in an era of rising uncertainty and rapid progress. This paper proactively designed e-Learning team teaching convergence liberal arts courses for prospective teachers by these social needs. It analyzed the empirical effects on the operation of the subjects to foster future talent who can converge and apply knowledge in various fields. The curriculum consisted of professors of mathematics, practical Arts, computer, and education, and was operated to convey convergent knowledge of information technology and humanities, and consisted of 15 liberal arts courses at J University. Besides, textbooks and teaching materials were also developed by the faculty. As a result of the primary research, prospective teachers who took the course generally showed high satisfaction with the class, especially for the faculty. The students' overall convergent thinking ability has increased to a statistically significant level (p<.01), and the students' major has been found to be irrelevant. On the other hand, it can be seen that communication, content convergence, and caring factors, excluding creativity factor, have all risen to a significant level.

Over the last three decades, there has been an increasingly strong emphasis on group-centered approaches to mathematics teaching. One primary responsibility for teachers who use group-centered instruction is to "check in", or intervene, with groups to monitor group learning and provide mathematical support when necessary. While prior research has contributed valuable insight for successful teacher interventions in mathematics group work, there is a need for more fine-grained analyses of interactions between teachers and students. In this study, we co-conducted research with an exemplary middle grade teacher (Ms. Green) to learn about fine-grained details of her intervention practices, hoping to generate knowledge about successful teacher interventions that can be expanded, replicated, and/or contradicted in other contexts. Analyzing Ms. Green's practices as an exemplary case, we found that she used exceptionally short interventions (35 seconds on average), provided space for student dialogue, and applied four distinct strategies to support groups to make mathematical progress: (1) observing/listening before speaking; (2) using a combination of social and analytic scaffolds; (3) redirecting students to task instructions; (4) abruptly walking away. These findings imply that successful interventions may be characterized by brevity, shared dialogue between the teacher and students, and distinct (and sometimes unnatural) teaching moves.
