This study was to investigate the perception, performance, and difficulties of process-based assessment for high school mathematics teachers. As a qualitative case study, two in-depth group interviews were conducted with 6 high school mathematics teachers working in Incheon area. The two groups were one with more experience in process-based assessment and the other with less experience. As results, there were differences between the participant teachers' perception of process-based assessment and their actual performance depending on the experience. All six math teachers thought that the process-based assessment was intended to confirm the learner's characteristics, to evaluate the process, and to provide feedback on a regular basis immediately and individually. However, in the practical performance shared by teachers, the purpose of assessment was to create a school record. A group with a lot of experience prepared assessment criteria according to the national curriculum achievement standards, established affective assessment plans, and tried to provide individual feedback on a regular basis. On the other hand, the inexperienced group recorded the affective characteristics discovered by chance and provided temporary and large-scale feedback regardless of the achievement criteria. Finally, we suggested some implications based on the study results.

In this study, we explored factors that affect high school student's affective attitude on mathematics with respect to the school mathematics instructoin, school mathematics assessment, mathematics textbook, private mathematics education, college entrance and career, and social atmosphere. Considering students' grade, major, academic level, gender, and school location, 1,029 high school students participated in the survey. To analyze the survey results, descriptive statistics, t-test, ANOVA, and chi-square test were conducted using SPSS ver 29.0. Results are as follows. First, generally, college entrance and career and school mathematics instruction affected students' affective attitude on mathematics. Second, according to student's academic level and gender, there was a statistically significant difference in the factors affecting the affective attitude on mathematics. Third, according to students' background, there was a statistically significant difference in students' responses to sub-categories of each factor. We suggested that to improve student's affective attitude on mathematics, diversity of the school mathematics instruction, improvement of the mathematics textbook, student's appropriate participation in the private mathematics education, improvement of student's perception of the utilization of the mathematics in the future and the importance of the mathemaitcs in the society, and parents' emotional support are needed.

In this paper, we examine high school in order to know their ability for understanding about fundamental functions, such as polynomial, trigonometric, logarithm and exponential functions which have learned from high school. The result of this study shows as follows. More than half students are not able to draw shape of given functions, except polynomial. More students do not fully understand about function properties such as domain, codomain, range, maximum and minimum value.

Geometry in school mathematics is the field that has the possibility of diverse approach such as Synthetic Geometry and Analytic Geometry. Synthetic Geometry is handled in middle schools and Analytic Geometry in the first year of high schools. Therefore, this research show for the possibility of using Synthetic Geometry in high schools which was learned already in middle schools and the way of integrating both of them concretely. This is expected to help students understand the mathematical meaning of figures a lot.

현재 초, 중, 고등학교의 수학교육 현실은 수학 개념의 정확한 이해에 초점을 맞추지 못하고 공식의 암기와 그것을 이용하여 단순한 문제 풀이에 시간을 많이 할애함으로써 수학의 기본적인 개념이나 기호의 정확한 사용법을 인지하지 못하고 계산 기능적인 면으로 치우치는 경향이 많이 나타나며, 문제 풀이의 창의적인 상황이 제시되지 않는 상태에서 교사 중심의 문제풀이 방법에만 의존하고 있다. 이러한 문제점 속에서 창의적인 문제 해결 방안을 구상할 수 있는 사고력의 배양에 소홀함이 있다고 볼 수 있다. 따라서 학생 스스로 의미를 파악하여 학습 할 수 있는 교수 방법이나 학습 방법에 대한 연구는 현실적으로 매우 시급한 상황에 처해있다. 이러한 상황에서 많은 수학교육자들은 학생들이 좀 더 쉽게 수학의 개념에 접근 할 수 있게 하기 위하여 많은 노력을 하고 있다. 그러한 노력 중의 하나로 테크놀러지를 이용한 수학교육을 말 할 수 있는데, 이는 실제로 수학교육에 긍정적인 영향을 준다고 알려져 있다. 본 논문은 현 고등학교 수학I의 등차수열에 관한 내용을 Mathematica를 이용하여 다각수(도형수)로부터 등차수열의 개념을 유도하였다.

In this study, pre-service mathematics teachers cultivated technology content teaching knowledge (TPACK) in the regular curriculum of the College of Education. The course was designed to enhance pre-service teachers' mathematical communication skills by using an application, which is a mobile mathematics learning content for the development of group creativity of high school students. The educational program to improve mathematics teaching expertise using the application for group creativity expression consists of pre-education, goal setting, planning, teaching at school, and evaluation. In this process, pre-service teachers evaluated technology tools. They also wrote a task dialogue, lesson play, reflective journal, and lesson plan to guide high school students to develop group creativity in both app activities. As a result of the educational program, pre-service mathematics teachers cultivated TPACK and enhanced their mathematical communication skills with high school students to develop group creativity.

Comparison of curriculum between various countries is a major research method for studying a course and content quoted on Korea's national curriculum. Therefore this research focuses on comparing and analyzing a new curriculum which Australia has announced on 2012 and conducting since 2015. From this research result, we found that Australia's curriculum achievement shows some unique characteristics. Such examples can be dealing a concept with real life context and proposing a mathematical content specifically. Also they introduce the definite integral by defining to the sum of series. There are other characteristics such as modelling motion, and numerical integration which Korea's highschool curriculum achievement doesn't deal with, and the content of vector calculus is handled more deeply. As a result of analyzing Australia's textbook, it fully deals with the supplementary notion to help understand mathematical definition. Hence further research will be needed later on to relieve the aspect of cognitive burden on Korean learners.

The study aimed to investigate what high-school students recognize mathematics textbooks and how they use textbooks in their learning mathematics in and out-of mathematics classrooms. For this purpose, we developed a set of interview questions in order to unpack what high-school students thought about mathematics textbooks and how they intended to use the textbooks for their learning mathematics. Eleven high-school students participated in the interview; the interview lasted for about an hour for each student. The data from the interviews were analyzed. The findings from the data analysis suggested as follows: a) the students seemed to consider mathematics textbooks as crucial medium for a mathematics classroom material and thus, they were likely to obliged to use the textbooks for preparing for not only tests and examination conducted regularly in schools but college entrance examination conducted nationwide; b) however, the students appeared to use the textbooks in limited ways in which they looked into the textbooks to prepare for mid-term or final exam only, not for their understanding mathematical contents as a main resource; and c) the students seemed to realize that they rarely have had an opportunity to develop mathematical thinking capabilities and understand mathematical ideas conceptually through the mathematics textbooks.

본 연구는 중 고등학교 교사 50명에 대하여 기하 문제의 논증기하적 또는 해석기하적 문제해결 전략이 학생들의 평가에 어떤 영향을 미치는가를 조사한 것이다. 중학교에서 고등학교로 진학하면 도형의 문제에 대한 해석기하적인 문제해결 능력은 교육과정 상 대단히 중요하게 가르쳐야 할 내용이다. 유클리드 기하에 바탕을 둔 논증기하의 지식은 좌표평면의 도형을 방정식으로 나타내고 연구하는 해석기하의 기본이다. 그럼에도 불구하고 많은 학생들은 논증기하적 문제해결을 선호하는 반면 해석기하적 문제해결은 어려워한다. 또한 논증기하적 문제 형태에는 논증기하적 문제해결 전략, 해석기하적 문제 형태에는 해석기하적 문제해결 전략을 구사하는 경향을 보인다. 본 연구는 중 고등학교 교사들의 기하 문제에 대한 내용 지식이 학생 평가에 미치는 영향에 초점이 맞추어져 있다.

통계 수업에서는 실제 자료를 직접 다루는 활동이 있어야 하며 이것은 계산기 또는 컴퓨터가 있어야 한다. 계산기 기능만으로는 많은 양의 자료를 반복해서 다루는데 문제가 있다. 그렇다고 통계 응용프로그램을 사용하는 것은 통계의 원리와 과정을 배우는 것이 목적인 고등학교 통계 교육과정에 맞지 않다. 이러한 면에서 볼 때 Excel은 계산기적 기능과 통계적 기능을 모두 갖추고 있으며 또한 시중에 많이 보급된 장점도 있다. 통계문제를 처리할 때 Excel의 계산기 기능을 사용하여 교과서의 원리대로 계산한 후 Excel의 통계기능을 이용하여 검토해 봄으로써 향후 통계 응용프로그램을 다루는 기초를 쌓을 수 있다. 그러나 Excel은 적분기능이 없어 연속분포에서 적분이 필요한 경우는 MathView를 사용하였다. 제7차 고등학교 통계 교육과정의 내용을 Excel을 활용하여 지도하는 모델을 개발해 봄으로써 새 수학과 교과서 개발을 위한 기초연구를 제공하고자 한다.
