SYMMETRIC IDENTITIES OF THE DEGENERATE MODIFIED q-EULER POLYNOMIALS UNDER THE SYMMETRIC GROUP
Kwon, Jongkyum,Pyo, Sung-Soo The Honam Mathematical Society 2018 호남수학학술지 Vol.40 No.4
Abstract of the article can be written hereAbstract of the article can be written here. Recently, several authors have studied the symmetric identities for special functions(see [3,5-11,14,17,18,20-22]). In this paper, we study the symmetric identities of the degenerate modified q-Euler polynomials under the symmetric group.
반성적 수업 분석지를 활용한 교육실습에서 중등수학 예비교사의 교수행동 및 인식 변화
권종겸,Kwon, JongKyum 한국수학사학회 2014 Journal for history of mathematics Vol.27 No.5
The purpose of this study is to assess the changes that occur to pre-service mathematics teachers by using survey on the self-reflection during their education practices. For four weeks of the education practice period, the changes to pre-service teachers are analyzed from teaching and learning perspectives. The teaching perspective is sub-categorized into lesson contents, teaching methods, and evaluation on teaching, and the learning perspective is sub-categorized into monitoring on learning, support for learning and evaluation on learning. The analysis shows that significant changes occur in teaching contents from the teaching perspective and in all the sub-categories from the learning perspective. Based on the analysis, preservice teachers are suggested to utilize self-reflection programs during their education practices to promote their professionalism in teaching.
Changes in Classroom Actions of In-Service Middle School Mathematics Teachers Due to Self-Evaluation
Ryoo, Ji Hoon,Kwon, Jongkyum,Lee, Dong Yub The International Promotion Agency of Culture Tech 2018 International Journal of Advanced Culture Technolo Vol.6 No.4
This research examines the impact of teachers' self-evaluation on their classroom interactions with students. Changes in class behavior were analyzed by following two experienced middle school teachers for one semester of self-evaluation, comparing their classes at the beginning and end of the semester. A qualitative research method was adopted to take, a deeper look at the effect of changes in the teachers' in class actions. Both of the teachers reported positive effects of implementing self-evaluation on their teaching pedagogy, focusing specifically on their interactions with students when asking question and giving feedback. By the end of semester, they were asking broader questions that encouraged their students to engage in deeper thought and, when giving feedback, the class atmosphere was much brighter with better communication due to the positive reinforcement provided. This research supports research into ways to enhance teachers' expertise and improve their teaching via self-evaluation, centering on teachers' actions in the classroom.
A NOTE ON DEGENERATE LAH-BELL POLYNOMIALS ARISING FROM DERIVATIVES
Xiangfan Piao,Yunjae Kim,Jongkyum Kwon 경남대학교 수학교육과 2021 Nonlinear Functional Analysis and Applications Vol.26 No.4
Recently, Kim-Kim introduced Lah-Bell polynomials and numbers, and investigated some properties and identities of these polynomials and numbers. Kim studied Lah-Bell polynomials and numbers of degenerate version. In this paper, we study degenerate Lah-Bell polynomials arising from differential equations. Moreover, we investigate the phenomenon of scattering of the zeros of these polynomials.
SOME IDENTITIES OF CARLITZ'S TYPE DEGENERATE q-CHANGHEE POLYNOMIALS AND NUMBERS
Yunjae Kim,박진우,Jongkyum Kwon 장전수학회 2021 Proceedings of the Jangjeon mathematical society Vol.24 No.1
Recently several authors have studied the degenerate q-special polynomials related to Carlitz's degenerate polynomials. In this paper, we introduce the Carlitz's type degenerate q-Changhee numbers and polynomials. And, we study some explicit identities and properties for the Carlitz's type degenerate q-Changhee numbers and polynomials arising from p-adic q-integral on Zp.

This study was subjected to 9th graders after making a conformity analysis about errors in function from a selected linear function domain learned in 8th grade, and using this we analyzed some errors learners have in the linear function domain. Learners showed the most deficiency in mastery of prerequisite facts concepts out of errors in linear functions and lack of skill in interpreting the content of the questions and technical errors occurred often as well. How the pre-service secondary school teachers prescribed these errors of linear function was analyzed from the point of problem solving strategies, accessing methods and whether or not the learner's error was used. Looking into the pre-service secondary teachers' prescription of the learners' errors in 3 fields, for the problem solving strategy a procedural strategy was used more than a conceptual strategy, and as for the accessing methods over 90% gave teacher led type explanations to the students. Also over 90% of pre-service secondary teachers did not use the learner's errors that turned up in problems.
경과시간 문제해결에서 보이는 초등학생의 인지적 특징 및 오류 분석
김정훈(Kim, Jung Hoon),권종겸(Kwon, Jongkyum),이동엽(Lee, Dong Yub) 학습자중심교과교육학회 2018 학습자중심교과교육연구 Vol.18 No.21
본 연구는 초등학교 학생을 대상으로 시간 계산과 관련한 내용 중 경과시간 문제 해결에서 나타나는 초등학생의 인지적 특징 및 오류를 분석하기 위한 목적으로 수행 되었다. 연구 목적을 달성하기 위해 먼저 교육과정을 분석하여 해당 내용의 인지적 특징을 추출하였으며, 문항목표 선정 후 문항목표에 맞는 설문지를 제작하여 2018년 7월 설문을 진행하였다. 이후 수집된 설문지의 오답률을 바탕으로 결과를 살펴보았 으며, 필요한 경우 일부 학생을 선정하여 초점그룹면담(FGI)을 수행하여 오답자의 문제해결 과정에 대한 오류를 보다 심층적으로 분석하였다. 연구 결과, 경과시간 문제해결은 3학년뿐만 아니라 6학년도 어려움을 겪는 소재임을 알 수 있었으며 경과시간 문제해결과 관련하여 큰 수에서 작은 수를 빼는 오류, 시간 표현의 오류, 24시간제 변환 요구에 따른 오류 등을 확인하였다. The purpose of this study was to analyze the cognitive characteristics and errors of elementary school students in the second grade of elementary school. In order to solve the research problems, the curriculum was first analyzed and the cognitive characteristics of the contents were extracted. After setting the goals according to the items, questionnaires were prepared and put into the research subjects. The results were analyzed based on the percentage of correct answers and wrong answers of the questionnaires collected, and some students were selected to conduct a focus group interview(FGI) to further analyze the errors in the problem solving process. As a result of the study, it was found that the elapsed time problem solving was not only difficult for the 3rd grade students but also for the 6th grade students. In relation to solving the elapsed time problem, we have confirmed errors in subtracting small numbers from large numbers, errors in time representation, and errors due to 24 hour conversion requests.
