An investigation into teachers’ perceptions of the national achievement test of primary English

심규남,이완기 한국초등영어교육학회 2011 초등영어교육 Vol.17 No.3

The purpose of this study is to investigate how primary school teachers of English perceive the national achievement test of primary English (hereafter NATPE). It also aims to investigate to what extent the washback effect of NATPE has on teachers’ practice in their teaching. For these purposes, the teachers’ usual way of teaching was surveyed, and an NATPE test contents were analyzed from the perspectives of teachers. From this analysis, some critical issues were raised, such as the dissonance between what the teachers do before and after the test implementation, and the impact of the test on the teachers’ perception and their practices. To carry out the research, a questionnaire consisting of some open-ended questions and some close-ended ones was administerd to over 100 teachers from different areas. An in-depth interview was also conducted to 15 questionnaire respondents in order to consolidate the data obtained from the questionnaire. The results indicate that teachers do not have enough information about the NATPE in terms of the four level distinctions of English achievement, and the differences between the neighbouring levels, the way of determining the cut-off point of each level. The results also show that teachers made efforts by employing a number of methods and strategies to help students prepare for the test, and compensate for their weakness after the test.

FPGA 컴파일 회피에 의한 효과적인 시뮬레이션 가속

심규호,박창호,양세양 한국정보처리학회 2007 정보처리학회논문지. 컴퓨터 및 통신시스템 Vol.14 No.3

In this paper, we proposed an efficient FPGA-based simulation acceleration method based on FPGA compilation avoidance, which can effectively decrease the long debugging turnaround time incurred from the every debugging process in the functional verification. The proposed method had been experimentally applied to the functional verification for a microcontroller design. It had clearly shown that the debugging turnaround time was greatly reduced while the high simulation speed of the simulation acceleration was still maintained. 본 논문에서는 FPGA 기반의 시뮬레이션가속을 통한 함수적 검증에서 매 설계오류의 수정 과정에서 필수적으로 진행되어야 하였던 긴 FPGA 컴파일 시간에 의한 오랜 디버깅턴어라운드시간을 단축할 수 있는 FPGA 컴파일 회피를 통한 효과적인 시뮬레이션가속 방법을 제시하였다. 마이크로컨트롤러 설계의 함수적 검증에 제안된 방법을 적용한 결과, 본 논문에서 제안된 방법이 시뮬레이션가속의 높은 시뮬레이션 수행 속도를 유지하는 동시에 디버깅턴어라운드시간도 크게 단축할 수 있음을 확인할 수 있었다.

PZT 박막에 대한 KFM 과 EFM 연구

심규한,김복기,김봉주,송경숙,조진형 한국물리학회 2007 새물리 Vol.54 No.2

We present an electrostatic force microscopy (EFM) and Kelvin force microscopy (KFM) study on PZT thin films. The EFM and KFM has been used as a nano-scale characterization tool for ferroelectric thin films. The contact mode is used for the writing process and the non-contact mode for the reading process. The interaction between the tip and the surface of the sample should be carefully analyzed to get useful information from the experimental results. Moreover, surface charging and the depolarization field are very important for understanding the imaging process. We have done the KFM and the EFM experiments on both sol-gel processed thin films of PZT and on the off-axis sputtered PZT thin films. The imaging processes of the KFM and the EFM are analyzed and carefully compared for both types of thin films. 우리는 본 논문에서 강유전체 물질인 PZT 박막에 대한 KFM 과 EFM 의 비교 연구 결과를 논의 하고자 한다. KFM 과 EFM 은 변형 SPM 기법으로 나노미터 영역에서 강유전체 박막의 분극반전 연구 수행에 이용되고 있다. 분극을 쓰는 과정은 AFM 상의 contact 모드에서 수행되었으며, 쓰여진 분극 정보를 읽는 과정은 non-contact 모드에서 수행되었다. 분극 쓰기와 읽기 과정에서는 상부 전극이 없는 상태에서 수행되기 때문에, 이 과정에서 일어나는 팁과 박막 표면 사이의 상호 작용은 주의 깊게 다루어 져야만 한다. 대표적인 예로 표면 전하 충전 (charging effect)과 편극소거장 (depolarization field)이 미치는 영향을 고려하여야 실험적인 사실을 올바르게 해석할 수 있다. 본 실험에서는 위와 같은 사실을 알아보기 위해 KFM 과 EFM 을 동시에 측정하였으며, 그 결과로부터 두 실험 결과의 차이점 및 공통점에 관해 논의할 것이다. 한편 박막의 방향성, 크기 등에 대해 알아보기 위해 두 가지 다른 방법으로 제작된 시료 (Sol-gel 방법 및 off-axis 증착 방법)에 관해 비교 연구도 수행하였다.

張載의 氣一元論에 對한 物理學的 理解

심규하 한국유교학회 2006 유교사상문화연구 Vol.27 No.-

張載는 萬物의 生滅 전 과정을 氣一元的 입장에서 糾明하였다. 그는 우주만물의 實體를 氣라고 闡明하고, 이 氣의 聚散작용에 의하여 우주만물의 生成과 消滅이 일어난다고 하였다. 그는 太虛, 氣, 萬物의 관계구조를 통하여 氣의 취산작용을 설명하고 있다. 이 세상은 모두 氣로 가득 차 있는데, 이 氣가 모이면 형체를 이루어 氣의 凝聚상태인 萬物이 되었다가 흩어지면 氣의 無形한 本然상태인 太虛로 돌아간다는 것이다.物理學은 구체적으로 드러나는 다양한 현상에 대한 통찰을 통하여 근원적인 법칙과 물질의 궁극적 본질을 탐구해 가는 學問이다. 따라서 물리학의 연구대상은 微細한 原子 속 素粒子에서부터 광활한 宇宙에 이르기까지 대단히 광범위하다. 이러한 물리학의 이론형성에 가장 중요한 비중을 차지하고 있는 개념은 ‘에너지’이다. 에너지는 相對性理論의 에너지-質量 等價原理가 알려지면서 우주 전체를 하나의 틀로 묶어 주는 槪念으로 자리 잡게 되었다. 質量을 가진 모든 物質들이 결국은 에너지의 변형이며, 더 나아가 우주의 모든 것들은 에너지의 어떠한 상태변화의 산물에 불과하다는 것이다. 그리고 에너지의 고유한 運動性과 그 基本的 相互作用을 통하여 우주만물의 끊임없는 변화가 가능한 것이다.장재의 기일원론은 관념적이고 주관적인 自覺을 통하여 萬物一體의 우주관을 확립하였다. 그러나 이러한 사상은 자칫 空虛한 주장으로 머물게 되어 일반인들을 啓導함에 있어서 다소 어려움이 있다. 따라서 만물의 본질과 변화의 문제에 대한 물리학의 성과를 통하여 모든 인간이 공유할 수 있는 객관적인 실증을 마련한다는 것은 우주자연에 대한 새로운 이해의 장을 마련할 수 있는 것이다.

Towards an understanding of teachers’ mediation in English language teaching in the primary schools.

심규남 한국초등영어교육학회 2009 초등영어교육 Vol.15 No.2

This small-scale study aims to investigate how primary teachers of English perceive their role as mediators with regard to English teaching. Thus, it examines the teachers’ current mediation principles and their perceived practice. This study also sets out to gain an in-depth understanding of further issues which emerged from the dissonance between the teachers’ beliefs and their perceived practice of mediation. In order to conduct the research, a mediation questionnaire was adopted from Williams and Burden (1997), and another open-ended questionnaire was constructed to obtain the qualitative data from 22 participants who are teachers of English and are in a Master’s degree program. The results of the study reveal that generally teachers hold and exercise their own beliefs regarding their role as mediators. However, they do not put some of their principles into practice. A number of significant factors were found to be responsible for this, these are: unfavorable teachers’ working conditions, dedication to the national curriculum, and their awareness of certain mediation principles. Some particular areas needing further investigation were identified in the last part of the study.

Does Performance Assessment System Operate as Intended in a Classroom-Based Assessment?

심규남 한국초등영어교육학회 2015 초등영어교육 Vol.21 No.4

The purpose of this study is to investigate how primary school teachers of English generally perceive performance assessment as part of classroom-based assessment (CBA) in the school. This study also examines a number of mainstream theories on language testing and assessment which are relevant to performance assessment and classroom-based assessment, while taking into account how performance assessment in the primary school classroom conforms to these theoretical principles. In order to conduct the research, the teachers’ usual method of performance assessment was surveyed two times, and their perceptions were analyzed from a total of 41 participants; a focused group interview was administerd to 8 teachers in order to consolidate the data obtained from the survey. According to the results of the study, the teachers generally believed that performance assessment in the schools operate properly; they were quite positive about the current performance assessment system and what they did as an assessor across the performance assessment cycle. However, there are a number of issues which need to be addressed: First, pre-announcement of performance assessment should be operated effectively in order to give stakeholders enough information on what the students are expected to do in the assessment activities. Second, the record and the report system need to be improved in order to communicate with stakeholders more successfully; through this, the feedback from the stakeholders could be more useful in improving what the teachers do in the classrooms. Some particular areas and issues needing further investigation were identified in the last part of the study.

An Analysis of Less-able Students’ Motivation in their English Learning in the Primary Schools

심규남 한국초등영어교육학회 2010 초등영어교육 Vol.16 No.1

This small-scale study aims to analyze how less-able students in the primary schools perceive certain components of motivation with regard to their English language learning. Thus, it examines the less-able students’ current perception of their English language learning. In order to conduct this research, a close-ended questionnaire was adopted and quantitative data of 81 participants were obtained from ten primary schools; then factor analysis and multiple regression analysis were carried out. The results of the study reveal that generally there are two major components which have an effect on the participants’ motivation with respect to their English language learning: intrinsic motivation and parents. While having relatively low intrinsic motivation, the participants are generally encouraged to learn English in order to meet their parents’ expectations. A number of significant minor components were also found to be responsible for the participants’ motivation such as the participants’ self-efficacy and teachers. Tentative implications and recommendations for the development of the less-able students’ motivation regarding English language learning are discussed in the towards the end of the study.
