Problem/Project based learning(PBL) is a student-centered teaching method in which students collaboratively solve problems and reflect their experiences. According to the results of PBL study and the experiences of the authors in PBL instruction, this paper introduced the necessities, output and significance of learning process PBL evaluation method and sums up our PBL evaluation process. The issue of appropriate and fair evaluation has been raised in untact (non-contact) university mathematics education due to the novel coronavirus (COVID-19) of the year 2020. To this end, when we had the course on < Basic Mathematics for Artificial Intelligence > for the summer semester held at S University in the summer of 2020. To ensure the fairness in evaluation and to improve the quality of our college math education, the PBL evaluation method was fully adapted. As a result, most of the students who took the lecture have learned a wide range of related knowledge without a single exception, and students agreed it is an ideal, fair, rational, and effective evaluation method applicable to other online courses in the era of untact education. This case was summarized in detail and introduced in this paper.

This study conducted a systematic review of mathematics teacher learning communities, especially the characteristics of teacher collaboration in community activities. Our review includes 14 research papers published in national academic journals indexed in KCI and 24 research papers in international academic journals indexed in SSCI from 2003 to 2019. Results show that the literature varied in research design, research topics, and patterns relating to teacher collaboration. While both international and national papers report teacher community activities concerning the organization, management, and participation, there were different levels of involvement, visions, and activities across the communities of practice. For example, research in national journals has presented teacher community as professional development while papers in international journals have focused on documenting teacher community becoming a reflective community of practice. This study contributes to understanding the interplay of context, conflicting epistemic culture, and professional agency in fostering collaboration in teacher communities. This paper also discusses relevant research methods to investigate mathematics teacher communities and insights into the policy and practice of mathematics teacher education.

This study is to establish the items on instructional evaluation based on the teacher’s practical knowledge in mathematics educations. Namely, this study deals with the items on how pre-service or in-service teachers reflect and revise their own or peer’s class. To accomplish this, first of all the items on instructional evaluation was developed by researchers of this study on the basis of the results of two previous study. One is the literature of Elbaz(1981) and the other is the literature of Hwang(2013). Elbaz(1981) defined the definition of practical knowledge and five sub-domains of the practical knowledge. On the other hand, Hwang(2013) defined the teacher knowledge in mathematics education and four sub-domains of the teacher knowledge. According to these four domains, Hwang(2013) developed the items on the instructional evaluation in mathematics class. From now on, based on these two study, this study was to develop the items on the instructional evaluation involving the practical knowledge. Futhermore, the final and ideal items on the instruction would be established through the reflection and comments of professionals such as mathematics teachers, professors, and researchers.

There are many factors that affect academic achievement, and the influences of those factors are also complex. Since the factors that influence mathematics academic achievement are constantly changing and developing, longitudinal studies to predict and analyze the growth of learners are needed. This study uses longitudinal data from 2014 (second year of middle school) to 2017 (second year of high school) of the Seoul Education Longitudibal Study, and divides it into groups with similar longitudinal patterns of change in mathematics academic achievement. The longitudinal change patterns and direct influence of mood and satisfaction were examined. As a result of the study, it was found that the mathematics academic achievement of the first group (1456 students, 68.3%) including the majority of students and the second group (677 students) of the top 31.7% had a direct influence on the mathematics class attitude. It was found that the mood and satisfaction of mathematics classes did not have a direct effect. In addition, the influence of mathematics class attitude on mathematics academic achievement was different according to the group. In addition, students in group 2 with high academic achievement in mathematics showed higher mathematics class attitude, mood, and satisfaction. In addition, the attitude, atmosphere, and satisfaction of mathematics classes were found to change continuously from the second year of middle school to the second year of high school, and the extent of the change was small.

This study is a basic study to effectively develop a mathematics experience object, an important tool and educational tool in mathematics education. Recently, as mathematics education based on action theory is emphasized, various mathematics experience objects are being developed. It is also used through various after-school activities in the school. However, there are insufficient cases in which a mathematics experience teaching tools is developed and used as a tool for explaining mathematics concepts in mathematics classrooms. Also, the mathematical background of the mathematics experience teaching tools used by students is unclear. For this reason, the mathematical understanding of the toolst for mathematics experience is also very insufficient.
Therefore, in this study, a development model is proposed as a systematic method for developing a mathematics experience teaching tools. Also, in this study, we developed ‘the Great Common Divisor' mathematics experience teaching tool according to the development model. Through the model proposed through this study and the actual mathematics experience teaching tool, the development of various tools for mathematical experience will be practically implemented. In addition, it is expected that various tools for experiencing mathematics based on mathematical foundations will be developed.
