In this study, 27 pre-service teachers presented virtual mathematics instruction to develop his/her own teaching practice ability. I found several attributes in their virtual mathematics instruction such as connecting contents, asking justification, encouraging students' communication, representing variously, and using ICT etc. These will be the characteristics of the future mathematics class. When peer pre-service teachers assess presenter's instruction quantitatively, there are differences in the results between expert and pre-service teachers. Pre-service teachers didn't find the elements of student self assessment or group assessment and communication activities at the virtual instruction. When they assess peers' virtual instruction qualitatively, the results are specific or new ones compared with the quantitative assessment elements. Thus I suggested some implications for the mathematics pre-service teachers' virtual instruction in the view of teacher education.

본 논문은 공학계열 학생들이 어셈블리 프로그래밍을 통해 x86 프로세서를 학습하는 교육 과정을 소개한다. 이 교육 과정은 어셈블리 프로그래밍을 통해 가상머신에서 프로그램을 실행시켜 학생들이 전공 교과 과정에서 학습한 마이크로프로세서 이론의 이해를 향상시키도록 도와준다. 작성된 어셈블리 파일은 NASM 을 이용하여 컴파일 되고, VMware 의 Workstation Player 가 컴파일러에 의해 생성된 바이너리 파일을 실행시키기 위해 사용되었다. 교육 과정은 마이크로프로세서 이론 수업에 맞추어 과제가 학생에게 주어지고, 학생들은 이론 수업의 이해를 바탕으로 결과물을 완성하고 이를 직접 시연하여 평가받았다.

The purpose of this study is to analyze and present what aspects of the concept of function prospective mathematics secondary teachers emphasize when designing a class that introduces the concept of function using curriculum and textbooks. For this purpose, virtual instruction and reflections on virtual instruction were analyzed. The results are as follows. The prospective mathematics secondary teachers consider and introduce the concepts of function as correspondences and processes. Their conception of function was consistently observed during virtual instruction and reflections on virtual instruction. The prospective mathematics secondary teachers' conception of function was closely related to the form of expressing functions. These results provi e implications for prospective mathematics secondary teachers' education for introducing the concept of function based on the dependent relation between variables presented in the 2015 revision of the national mathematics curriculum.
