작도 문제는 역사적으로 아주 오래된 문제 중의 하나일 뿐만 아니라, 현재 우리 나라 기하 교육에 있어 매우 중요한 역할을 하고 있다. 즉, 평면 기하의 중심 정리들 중의 하나인 삼각형의 합동 조건들을 도입하기 위한 기초로 주어진 조건들(세 선분, 두 선분과 이들 사이의 끼인각, 한 선분과 그 양 끝에 놓인 두 각)에 상응하는 삼각형의 작도가 행해진다. 그러나, 현행 수학 교과서나 수학 교수법을 살펴보면, 작도 문제 해결 방법 및 지도에 대한 연구가 미미한 실정이다. 본 연구에서는 작도 문제의 특성, 작도 문제의 해결 방법 및 지도에 관한 접근을 모색할 것이다. 이를 통해, 학습자들이 다양한 탐색 활동 속에서 작도 문제를 탐구할 수 있는 이론적, 실제적 근거를 제시하고, 수학 심화 학습에 작도 문제를 이용할 수 있는 가능성을 제시할 것이다.

현재 초, 중, 고등학교의 수학교육 현실은 수학 개념의 정확한 이해에 초점을 맞추지 못하고 공식의 암기와 그것을 이용하여 단순한 문제 풀이에 시간을 많이 할애함으로써 수학의 기본적인 개념이나 기호의 정확한 사용법을 인지하지 못하고 계산 기능적인 면으로 치우치는 경향이 많이 나타나며, 문제 풀이의 창의적인 상황이 제시되지 않는 상태에서 교사 중심의 문제풀이 방법에만 의존하고 있다. 이러한 문제점 속에서 창의적인 문제 해결 방안을 구상할 수 있는 사고력의 배양에 소홀함이 있다고 볼 수 있다. 따라서 학생 스스로 의미를 파악하여 학습 할 수 있는 교수 방법이나 학습 방법에 대한 연구는 현실적으로 매우 시급한 상황에 처해있다. 이러한 상황에서 많은 수학교육자들은 학생들이 좀 더 쉽게 수학의 개념에 접근 할 수 있게 하기 위하여 많은 노력을 하고 있다. 그러한 노력 중의 하나로 테크놀러지를 이용한 수학교육을 말 할 수 있는데, 이는 실제로 수학교육에 긍정적인 영향을 준다고 알려져 있다. 본 논문은 현 고등학교 수학I의 등차수열에 관한 내용을 Mathematica를 이용하여 다각수(도형수)로부터 등차수열의 개념을 유도하였다.

제4차 산업혁명 시대를 살아갈 학생들에게 필요한 핵심 역량으로서 컴퓨팅 사고력의 중요성이 강조되고 있으며, 이와 관련하여 다양한 연구가 진행되고 있다. 그러나 대부분의 연구가 교수 학습 방법을 개발하고 효과성을 검증하는데 치중하는 반면, 학습자의 컴퓨팅 사고력을 어떻게 평가하고 피드백을 줄 것인지에 대한 연구는 부족하다. 따라서 본 연구에서는 컴퓨팅 사고력 평가에 관한 연구 중에서 KCI에 등재된 9편의 연구를 분석하고, 시사점을 도출하였다. 이는 컴퓨팅 사고력 평가에 관한 향후 연구의 방향을 제시해줄 것이라 기대한다.

In this paper, we investigated and analyzed how freshmen in science and engineering colleges understand the limit and the continuous concept of function. The survey found that there were more college students who did not do so than those who understood each concept by linking the concepts together. Therefore, in order to teach college general mathematics, It is necessary to analyze how college students are connecting mathematical concepts. And it is necessary to apply teaching-learning methods suitable for individuals.

This research was explored the effects of the application of the team-based classes on the self-directed learning, the academic self-efficacy, and the level of learning satisfaction of the nursing students. Study subjects are 104 nursing students from one university from G region. The data were analyzed by t-test, one-way ANOVA, paired t-test, Pearson's correlation coefficients. With regard to the differences between the levels of the learning satisfaction, the differences were shown (t=4.410, p<.05). Regarding the self-directed learning, it rose to the average of 3.50 points after the application of the team-based learning from the average of 3.39 points. It showed a difference (t=-2.083, p=<.05). And the academic self-efficacy rose to 3.65 points from the 3.12 points after the application of the self-based learning. And it showed a difference (t=-14.175, p=<.001). The level of the learning satisfaction was shown to be over the middle with the average of 3.73 points. And the self-directed learning after the application of the team-based learning showed an academic self-efficacy (r=.512, p<.001), a level of the learning satisfaction (r=.421, p<.001), and a positive relationship. It was proven that the team-based learning can cultivate the capabilities for effectively solving the clinical problems.

This study aims to testify the effect of reading and writing abilities improvement program for elementary school children from multicultural families. Methods: The research design used in this study was a non-equivalent control group pretest-posttest research design. The participants were divided into two groups, an experimental group(n=9) and a control group(n=8). Data were analysed by using Mann-Whinety U test, Wilcoxon Signed Ranks, Cohen's d with SPSS(PASW)18.0 program. Result: Significant differences were found in scores for reading ability (z=-2.668, p=.008, ES(d)=0.6) and writing ability (z=-2.670, p=.008, ES(d)=0.5) in experimental group. Conclusion: The results indicate that the reading and writing abilities improvement program should be used with elementary school children of multicultural families to help them and to improve their reading and writing abilities.

Cell division in biological education is an important and unintelligible unit. Most of students have no interest in learning the content, and don't concentrate on it because cell division unit contains relatively difficult content. In this vein, during considering the effective learning methods, the researcher found role-play as the method for student's positive access to important and unintelligent learning content. Effect of role-play on their learning achievement of science was analysed through the Chapter of cell division on 3rd grade of middle school students. For this study three levels of middle school students were selected from the school located in Seoul. And divided this students into experiment group and control group by 2 classes respectively. Before putting into practice this instruction, there took into account the before and after of students' learning achievement and their learning attitude by using same questionnaire. On the other hand, the researcher put into practice co-variate analysis by using SPSS statistical package as the measurement method.

This study investigated the perceived significance of laboratory(lab) notebooks and the creation and maintenance of them from the perspectives of graduate students and professors in science fields. Semi-structured interviews of three professors and four graduate students were conducted. The interviewees were from three university laboratories of physics, chemistry and biological science. While professors perceived administrative continuity to be a reason for creating lab notebooks, students valued lab notebooks as a memory, and emphasized learning professional knowledge and skills through the recordkeeping practice. Students understood the ownership of lab notebooks and professors wanted to keep lab notebooks until they retire. Interviewees focused more on the content of lab notebooks rather than the form and the structure. They were also not willing to adopt an electronic lab notebook system. Students learned how to create lab notebooks through a course, their current or former academic advisors, seniors in the lab or well-written sample lab notebooks. In particular, students have learned how to create lab notebooks within their laboratories, which are considered to be communities of practice. In this sense, professors responsible for managing laboratories play an important part in teaching students the recordkeeping practice. University archives should also be more concerned with managing and preserving lab notebooks created from their universities.

The purpose of this study was to identify learners with poor learning in basic cooking practice subjects for college students majoring in cooking, operate a basic practical ability improvement program, and apply an action learning teaching method. We tried to analyze the subjective perception of learners using the Q methodology. In addition, it was intended to improve the major competencies for the operation of practical programs related to cooking training, field training, and employment of learners. The survey was conducted from May 1st to 20th, 2020 for first-year students in C cuisine major. As a result of the analysis, a total of three types were derived. Type 1 (N=7): Self-directed learning effect type, Type 2 (N=8): Problem Solving Effect Types, Type 3 (N=6): Peer learning effect type, each unique feature type Was analyzed as. Through the progress of this study and the derivation of implications, it is expected that it will be useful data for the application of teaching and learning methods related to practical work and program operation in cooking-related departments.

The purpose of this study is to examine the effectiveness of flipped learning lesson on the human social behavior and social environment subject. In order to achieve this object, this study conducted qualitative analysis of class-evaluation and self-evaluation and quantitative analysis using the questionnaire. As a result, it was confirmed that flipped learning method works very effectively in the theoretical curriculum of social welfare. Participants assessed that their comprehension and presentation skills improved. In addition, their self-esteem improved after this class. However, this teaching may be rather negative for participants who had difficulties in pre-learning or a passive attitude. In order to improve this problems, the instructors should be prepared to make pre-learning better. As well as, they should prepare countermeasures for passive participants, and help interact well among the participants.
