The purpose of this research is to compose the curriculums of mathematics for the technical high school students to ream their own majors effectively. First, we analysed the goal of mathematics education in high school and the goal of education in technical high school and the 6th and 7th National Curriculums of mathematics. And next, we researched the reality and the necessity of mathematics education in technical high school. As the result of this analysis, we found some problems of mathematics education in the technical high school. So we composed the scope, the sequence, and the units of mathematics textbook which reflect the curriculum of technical high school.

This research is that concern in mathematics education of Technical high school Department of Electricity in the 7th educational curriculum. we indicated problem compare 7th with 6th mathematics curriculum subject contents in Technical high school Department of Electricity. And examine major subject contents, analyzed contents of mathematics that must supplement and mathematics which use in major subject. Established contents of electricity mathematics education that need to major learning to satisfy target of technical high school technical education that is presented in the 7th training courses with this analysis. Also, we hope these results are into consideration when writing new mathematics text in Technical high school Department of Electricity.

In this paper we represented the results of surveying on the present condition of mathematics education and the contents of the mathematics text books that are usually taught in Art High Schools interest in mathematics subjects and to achieve the higher level of mathematical abilities. We would like to raise their interest in mathematics and to improve the efficiency of teaching level on the basis of the 7th Mathematics Curriculum Revision. Some suggestions are of offered by considering the level of their mathematical abilities in Art High Schools and the present contents of the mathematical subjects from following views ⑴ the aspect of studying method ⑵ the aspect of revising contents of mathematics textbooks for them ⑶ the aspect of educational policies for Art High Schools

The purpose of this survey-based study was to investigate high school students' perceptions of mathematics teachers' implementation of Universal Design for Learning (UDL)-based practices and technology in their mathematics classes in 2017. A total of 303 high school students in South Korea participated in this online survey on teachers' use of technology for instructional practices, the frequency of technology tool use, and the meeting of UDL guidelines in mathematics instruction. According to frequency analysis, high school students generally perceived their teachers' mathematics teaching as somewhat positive in providing multiple means of representation, action and expression, and engagement. However, mathematics teachers' implementation of technology tools in their mathematics classes was generally limited. This study indicated significant and positive relationships between variables regarding the use of technology tools and teachers' efforts to follow the UDL guidelines. Applying the Chi-squared test, we further examined how each survey result differed according to high school students' academic achievements and grade levels.

This study was executed in M elementary school for a week, T elementary school for a week, N high school for a week, and S high school for a week in 2000. There were mathematics teacher interviews, mathematics classroom observations, and student interviews in each school. We can draw the conclusion from this study as follows. Firstly, the teaching of mathematics in both elementary and high school was very good in the standard of mathematical concepts, procedures, and connection. Secondly, it is very good in the standard of mathematics as problem solving, reasoning, and communication. Thirdly, it is not so good in the standard of promoting mathematical disposition. Fourthly, it is good in elementary schools, but not in high schools regarding the standard of assessing students' understanding of mathematics. Fifthly, it is very good in elementary schools, but not so good in high schools regarding the standard of learning environments.

본 연구는 고등학교 학생들의 수학의 본질에 대한 인식과 신념 및 수학 학습에 대한 신념을 살펴보고, 수학교육의 발전을 위한 시사점을 찾아보는 데 목적이 있다. 이를 위해 일반계고 학생들과 전문계고 학생들의 수학의 본질에 대한 인식과 신념, 수학 학습에 대한 신념을 비교 분석하였고 각 학교의 학생들에 대한 신념의 차이점을 살펴보았다. 그 결과, 일반계고와 전문계고의 학교 유형별로 수학의 본질에 대한 인식과 신념, 수학 학습에 대한 신념의 차이가 두드러지게 나타났다. 또 고등학교 학생들은 수학의 가치성에 대해 낮게 평가하였으며, 일반계고 학생들이 전문계고 학생들보다 수학의 '심미적 가치', '도야적 가치' 및 '실용적 가치'를 더 낮게 평가하고 있는 것으로 분석되었다.

This work aims to investigate mathematics teachers' knowledge and belief on the high school probability and statistics. For this aim, two research questions are estabilished as follows. (1) How is mathematics teachers' knowledge on the main contents of the high school probability and statistics in the 7th mathematics curriculum? (2) What is mathematics teachers' belief on the high school probability and statistics? Survey and interviews were carried out to answer the above research questions. Subjects of the survey were 2 7mathematics teachers who were answered to questionnaire. Among them, 3 volunteers were chosen by provinces for in-depth interview. Research findings in mathematics teacher's knowledge are as follows. Firstly, mathematics teachers do not have much of mathematical knowledge on the newly added and changed contents of the high school probability and statistics in the 7th mathematics curriculum. Secondly, mathematics teachers do not change their teaching-learning method for probability and statistics. Thirdly, many teachers think that the use of technology and reconstruction of the textbooks are required in teaching and learning of the high school probability and statistics. But, they stick on their own way. Research findings in mathematics teachers' belief are as follows. Firstly, many mathematics teachers view the nature of statistics as a branch of the applied mathematics and put the value of high school probability and statistics on the practical usefulness, Secondly, many mathematics teachers think that understanding concepts and improving problem solving ability are the best method of the teaching and learning. Thirdly, many mathematics teachers think that high school probability and statistics textbooks should cause motivations and interests in order not to give up studying probability and statistics. It is expected that the above findings can be used to change teachers' teaching and learning methods and to improve teachers training program.

We continue the study of power-Armendariz rings over IFP rings, introducing $k$-power Armendariz rings as a generalization of power-Armendariz rings. Han et al. showed that IFP rings are 1-power Armendariz. We prove that IFP rings are 2-power Armendariz. We moreover study a relationship between IFP rings and $k$-power Armendariz rings under a condition related to nilpotency of coefficients.
