This study aims to examine individual perceptions and lived experiences of the Net generation of student teachers and the previous generation of teachers about their technology use in education. The participants of this study include 106 pre-service teachers and 50 in-service teachers from one teacher education university in Korea. Employing a mixed methodology, we first empirically examined the participants' perceptions toward multiple variables related to technology use in education, namely (a) past ICT experiences in schools, (b) personal computer use, (c) constructivist belief, (d) computer efficacy, (e) attitude toward computer in education, and (f) prospective computer use. In addition, we conducted face-to-face interviews with selected participants for the in-depth investigation of their lived experiences about technology use, beliefs, and attitude. Results indicate that there are significant differences between in-service and pre-service teachers in their prior experiences with technology in schools. However, the pre-service and in-service teachers did not differ significantly in their beliefs, attitude and other technology-related variables, which may indicate the danger of generational determinism in the Net Generation debate. The analysis of interview narratives revealed two major themes about the interplay of one's agency and structural changes in the participants' lived experiences with technology use in education: (a) transition from negative past experiences to opportunities for positive computer use, and (b) attitudes formation and change through apprenticeship experiences and structural influences. In conclusion, this study suggests that the Net Generation debate should move beyond dichotomous or techno-centric thinking. There is a critical need to pay more attention to develop deeper understandings of the fundamental diversity existing within the generation itself. Implications for teacher education are also discussed.

This study identifies and tracks changes gender differences in adolescent users' problematic online behavior. This study used Korea Youth Panel Survey (KYPS), which has tracked respondents over 7 years, with self-control theory and social learning theory applied as a theoretical framework. The model included individual-level variables such as self-control and respondent's experience of problematic behavior (offline), as well as socialization variables such as the number close friends who engaged in problematic offline behavior, parent-child relationships, and parental monitoring. Dependent variables included problematic online behavior, unauthorized ID use (ID theft) and cyberbullying (cursing/insulting someone in a chat room or on a bulletin board). Control variables consisted of academic performance, time spent on a computer, monthly household income, and father's educational attainment. Random and fixed effects models were performed by gender. Results supported self-control theory even for the within-level analysis (fixed effects models) regardless of gender, while social learning theory was partially supported. Only peer effects were found significant (except for unauthorized ID use) among girls. Year dummy variables showed significant negative associations; however, academic performance and time spent using computers were significant in some models. Father's educational attainment and monthly household income were found insignificant, even in the random effects models. We also discuss implications and suggestions for future research and policy makers.

정보화 시대의 도래로 인해 학교 현장뿐만 아니라 사회의 전 분야에서 인터넷의 사용이 폭발적으로 증가하고 있는 것이 현실이다. 고객 분석이 화두가 되는 온라인 마켓에서는 성인의 성별 요인이 인터넷 사용에 있어 하나의 중요한 요소로 인식되어 시스템 설계와 개발에 큰 영향을 미치는 요인이 되기도 한다. 마찬가지로, 대상자가 인터넷의 환경에 처음 노출되어 그 정도가 심화되어 가는 초등학생을 대상으로 성별, 인종, 문화 등 따라 그 개발과 설계를 근본적으로 달리 해야 하는가 하는 것은 최근의 중요한 이슈의 하나로 생각될 수 있다. 본 연구에서는 현장 교사들의 많은 경험상 성별이 큰 영향을 미칠 것이라는 막연한 생각에 분명한 통계적 결과를 제시하여 a) 성인들과 같이 성별에 따라 교육용 시스템의 설계와 개발을 해야 할 필요성이 있는지에 대한 근본적인 의문에 답할 뿐만 아니라 b) 세부적으로 어떠한 요인들이 초등교육용 웹 사이트 개발에 핵심적 요소가 될 것인가를 192명의 설문결과를 바탕으로 분석하여 그 결론과 시사점을 도출하였다.

본 연구에서는 국제 교육성취도 평가협회가 시행한 ICILS 2013의 교사 설문 자료를 활용하여 우리나라 중학교 과학 교사의 ICT 활용 실태를 다른 나라와 비교하였다. ICILS 2013은 중학교 2학년을 대상으로 하고 있으며, 18개 참여국 중 컴퓨터 정보 소양 점수가 높은 호주, 체코, 노르웨이, 폴란드와 우리나라 과학 교사들의 ICT 활용 실태를 비교하였다. 본 연구에서는 ICILS 2013의 교사 설문지 중에서 과학 교사의 ICT 활용 실태를 분석할 수 있는 9문항을 선택하였는데, 문항들은 교사의 컴퓨터 이용 실태, 수업에서 ICT 활용 현황, 학교의 ICT 활용 지원 환경의 범주로 나누어 분석되었다. 우리나라 중학교 과학 교사의 컴퓨터 사용 실태를 보면, 컴퓨터를 비교적 많이 사용하며 컴퓨터에 대한 자아효능감도 다른 나라에 비해 높은 편이었다. 그러나 일반적인 컴퓨터 활용은 잘한다고 응답한 비율이 높지만 교수학습과 관련된 컴퓨터 활용에서는 낮은 자신감을 나타내었다. 수업에서 활용에서도 비교적 다양한 응용프로그램을 사용하지만 프레젠테이션이나 그래픽 소프트웨어에 대한 활용의 비중이 높은 편이고 학습활동이나 교수활동에서도 교사주도의 정보 제공이나 과제 제시에 대한 활동의 비중은 높지만 협업이나 상호작용이 많은 활동에서는 낮은 응답을 나타내었다. 또한 우리나라 과학 교사들은 ICT 활용하는 것에 대해서 긍정적인 관점보다는 부정적인 관점을 많이 가지고 있었다. 학교에서 컴퓨터 관련 자원을 지원하는 정도는 지원이 부족하다고 응답하는 경우가 많았으며 조사 항목 대부분에서 호주나 체코에 비해 지원 정도가 낮다고 응답하였다. 또한 충분한 ICT 기기나 컴퓨터가 구식 모델이고 디지털 학습 자료가 부족하다고 응답하였다. 여기서 드러나 문제점을 개선하기 위해서는 ICT 교육 인프라에 대한 지속적인 지원과 더불어 학생활동 중심의 ICT 교수학습 방법에 대한 개발과 보급이 필요할 것으로 보인다.

1988년 개인용 컴퓨터를 활용하는 교육용 컨텐츠가 개발되기 시작한 이래 우리나라의 교육용 컨텐츠의 수는 엄청나게 늘어났다. 그러나 이러한 컨텐츠들이 교육과정이 바뀔 때마다 각 교과의 학습 주제가 재편성됨으로 인해 지속적인 사용이 어려워지고 있다. 그러므로, 교과별로 변하지 않는 학습 요소를 정립한다면 교육과정이 변하더라도 자료를 재분류하지 않고도 기존에 만들어진 질 높은 자료들을 충분히 사용할 수 있을 것이다. 이러한 취지에 따라, 작년(2003년)에 교육인적자원부 및 한국교육학술정보원 측에서는 수학 교과를 시범 교과로 두어 현 교육과정을 지원하되 교육과정 개정에도 유연하게 대처할 수 있는 분류 방법(틀)을 마련하고자 하였다. 결과적으로, 이 연구에서는 그들의 요청에 따라 교육과정이 개정되더라도 수학 교과에서 나뉘거나 바뀌어 다뤄지지 않을, 즉 하나의 독립적이면서도 중요한 수학 내용을 '단위'라 칭하고, 이를 선정하는데 초점을 두었다. 이 연구에서 마련한 단위는 총 339개이고, 각 단위의 구체적인 내용을 이해하기 위하여 마련한 요소는 총 1191개이었다.

We are at the onset of a major revolution in education, a revolution unparalleled since the invention of the printing press. The computer will be the instrument of this revolution. Computers and computer application are everywhere these days. Everyone can't avoid the influence of the computer in today's world. The computer is no longer a magical, unfamiliar tool that is used only by researchers or scholars or scientists. The computer helps us do our jobs and even routine tasks more effectively and efficiently. More importantly, it gives us power never before available to solve complex problems. Mathematics instruction in secondary schools is frequently perceived to be more a amendable to the use of computers than are other areas of the school curriculum. This is based on the perception of mathematics as a subject with clearly defined objectives and outcomes that can be reliably measured by devices readily at hand or easily constructed by teachers or researchers. Because of this reason, the first large-scale computerized curriculum projects were in mathematics, and the first educational computer games were mathematics games. And now, the entire mathematics curriculum appears to be the first of the traditional school curriculum areas to be undergoing substantial trasformation because of computers. Recently, many research-Institutes of our country are going to study on computers in orders to use it in mathematics education, but the study is still start ing-step. In order to keep abreast of this trend necessity, and to enhance mathematics teaching/learning which is instructed lecture-based teaching/learning at the present time, this study aims to develop/present practical method of computer-using. This is devided into three methods. 1. Programming teaching/learning method This part is presented the following five types which can teach/learn the mathematical concepts and principle through concise program. (Type 1) Complete a program. (Type 2) Know the given program's content and predict the output. (Type 3) Write a program of the given flow-chart and solve the problem. (Type 4) Make an inference from an error message, find errors and correct them. (Type 5) Investigate complex mathematical fact through program and annotate a program. 2. Problem-solving teaching/learning method solving This part is illustrated how a computer can be used as a tool to help students solve realistic mathematical problems while simultaneously reinforcing their understanding of problem-solving processes. Here, four different problems are presented. For each problem, a four-stage problem-solving model of polya is given: Problem statement, Problem analysis, Computer program, and Looking back/Looking ahead. 3. CAI program teaching/learning method This part is developed/presented courseware of sine theorem section (Mathematics I for high school) in order to avail individualized learning or interactive learning with teacher.

The main purposes of this study were (a) to analyze the research trend of educational use of tangible technology, (b) to identify tangible learning mechanisms, and potential benefits of learning with tangible technology, and (c) to provide references and future research directions. We conducted a systematic literature review to search for academic papers published in recent five years (from 2013 to 2017) in the major databases. Forty papers were coded and analyzed by the established coding framework in four dimensions: (a) basic publication information, (b) learning context, (c) learning mechanism, and (d) learning benefits. Overall, the results show that tangible technology has been used more for young learners in the kindergarten and primary school contexts mainly for science learning, to achieve both cognitive and affective learning outcomes, by coupling tangible objects with tabletops and desktop computers. From the synthesis of the review findings, this study suggests that the affordances of tangible technology useful for learning include embodied interaction, physical manipulations, and the physical-digital representational mapping. With such technical affordances, tangible technologies have the great potential in three particular areas in education: (a) learning spatial relationships, (b) making the invisible visible, and (c) reinforcing abstract concepts through the correspondence of representations. In conclusion, we suggest some areas for future research endeavors.

The activities of teaching and learning are to try to reach the lesson object most closely in many ways. Considering that the lesson objects are to get the principle or law of a concept, to acquire the mathematical function, to master it through repeated exercises and to solve mathematical problems, we need many ways to reach such objects. Among the many ways, we can first think of one: the students will learn with curiosity and according to their own ability or advancing level in learning when teachers study and prepare necessary contents enough in advance by using computers, showing the right program to learners' needs. For example, defining definite integral by measuration by parts will help understand measuration by parts well and know the meaning of definite integral correctly, In teaching and learning by the use of this program, the educational effects are expected as follows. 1. It is thought that this program will stimulate the desire for and interest in learning because it used animation and acoustic effect. And voluntary and positive thinking activity will be shown. 2. It is expected that the conviction of formulas will be got and the concept of definite integral will be remembered firmly by showing how to measure the width of circle with the use of measuration by parts in various other ways instead of the ways used at present. 3. It is expected that students will feel the pleasure of mathematics in life when they recognize mathematical facts scattered really in our life rather than mathematical difficulties. 4. It is expected that the repeated review of programs already designed will remove the fear of incomplete parts and help review again. 5. It is certain that positive attitude in life will be formed as teacher-centered class is changed into learner-centered class and unwilling study is changed into self-oriented study. However, I think this program is insufficient for humanbeing-centered education given directly in contact with students on the ground of the variety in mathematical education and applications in many ways. And mechanically inhuman computers leave some solutions to be desired

The world has witnessed a phenomenal growth in information and communication technologies (ICT). The development of new broadband communication services convergence of telecommunication with computers and recent developments in the field of communication protocol have fostered challenges as well as offerings in the wide-ranging use of ICT to support the creation of dynamic and interactive teaching and learning environment. By emergence of ICT, most of education and training institutions are struggling to integrate ICT and education and training systems. It is so important to apply proper delivery systems for utilization of the computerized teaching and learning contents in the classrooms. It will be a preliminary activity for building open and flexible distance teaching and learning systems in developing countries. In this paper, we would like to suggest and recommend the proper delivery systems for utilization of the computerized teaching and learning contents in the classrooms for education sector reform in developing countries.
