The purpose of this article is to develop a program for teaching Type I and Type II errors in one sample. In this program, the concepts of two errors are visually explained, and the probabilities of two errors are also visually displayed as the rejection region changes or the sample size changes. Also, in this program, the power curve and the operating characteristic curve are visually displayed in terms of the parameter value of interest.

The purpose of this study is to identify the types of professional teaching practice of Home Economics teachers who are working at Korean secondary school for changing their professional teaching practice and developing home economics curriculum. A mail questionnaire, Professional Teaching Practice(PTP) was used to survey randomly selected 525 Home Economics teachers. The professional teaching practices examined were customary-instrumental, interactive and reflective practices. Customary-instrumental practice was the predominant type of professional teaching practice used by Home Economics teachers. About 26% of the teachers used reflective practice, and 14.67% used interactive practice. Only the number of students was significantly related to their professional teaching practices. Five influential factors on teaching practices identified by Home Economics teachers emerged in the following order: examination-centered educational system, lack of class hours, lack of resource materials and facilities, demands from the Ministry of Education, school administrators, or parents, and large class sizes.

Objective: This study was conducted to examine the mediating effects of play teaching efficacy in the relationship between the organizational health of teacher workplaces and the creative personality of the teachers. Methods: The Pearson product-moment correlation analysis and one-way ANOVA were conducted for data analysis using SPSS 25.0. For mediating analysis, Baron & Kenny's (1986) multiple regression analysis using SPSS 25.0 and the Sobel test were also implemented. Results: There were significant differences in the organizational health of the workplaces according to age, years of working experience, type of workplace, and daily working hours. For play teaching efficacy, there were significant differences according to age, education level, years of working experience, type of workplace, and daily working hours of the teacher. On the other hand, significant differences were found in terms of age and education level in relation to the teacher having a creative personality. Play teaching efficacy was found to have a full mediation effect on the relationship between the organizational health of the workplace and the creative personality of the teacher. Conclusion/Implications: The organizational health of the workplace and play teaching efficacy should be improved in order to enhance the creative personality of teachers in early childhood education.

The present study is devoted to the development of a simplified teaching method whereby the control data of the 3-dimensional operations of a playback-type trial robot can be stored in a personal computer. The control data of the 3-dimensional operations are given using an instruction wand handled by an operator. The operator's task is only to track a desired robot path with the wand. The 3-dimensional position of the wand are measured by ultrasonic devices, the principle of which was developed for this study and is introduced in detail. In order to clarify the applicability of this method, experts were performed with respect to a continuous-path teaching and a pick-and-place task teaching which are typical jobs of robot operators.

The Direct Arm(DDA) is a SCARA typed direct drive manipulator with three degree of freedom(DOF) using the direct motor of the NSK company. In the paper, we propose a convenient interface for the SCARA-type robot which is practical to use. The proposed Visual Robot Teaching Mode using 3D graphics replaces the current teaching box. And besides this graphical teaching software can be implemented on the PC which is company used as a robot controller. This program was developed for the Windows 95 OS.

본 연구는 「경기교육종단연구(GEPS)」의 2019년 고등학교 2학년 자료를 이용하여 학습자가 지각한 수학 수업방식(교수자중심, 학습자중심)이 수학자기효능감에 미치는 영향력에 대한 이질적 잠재집단을 탐색하였다. 탐지된 잠재집단의 특징을 프로파일링하기 위해 교수·학습 관련 변인들의 분포를 확인하고, 구조방정식모형을 설정하여 다집단 분석을 실시하였다. 분석결과, 두 개의 잠재집단이 탐지되었으며, 그 특성에 따라 교수자형 집단과 학습자형 집단으로 명명하였다. 탐지된 교수자형과 학습자형 집단에서 교수자중심수업에 대한 지각과 학습자중심수업에 대한 지각, 그리고 수학교수능력에 대한 인식은 분포가 유사하였지만, 수학자기효능감과 수학흥미, 수학수업참여의 경우 교수자형 집단이 학습자형에 비해 높게 나타났다. 또한 교수자형 집단은 학습자형에 비해 수학교수능력에 대한 인식이 수학자기효능감과 수학수업참여에 미치는 영향이 크게 나타났으며, 학습자형 집단은 교수자형에 비해 수학흥미가 수학자기효능감과 수학수업참여에 미치는 영향이 크게 나타났다. 본 연구는 경로모형기반의 단위 분할 탐색 REBUS-PLS 방법을 적용함으로써 수학 수업방식이 학습자에게 미치는 영향력에 관한 새로운 연구방법을 제시하였다.

본 연구는 초등학교 학습자 특성에 따른 프로그래밍 교육방안 마련을 위해 구체적 조작활동 교구인 디키-3000을 활용한 프로그래밍 교육을 실시한 후 Grasha와 Reichmann(1974)가 제안한 6가지 학습양식 유형별 프로그래밍 성향 및 성취도 분석을 실시하였다. 연구결과 학습양식 유형에 따른 프로그래밍 성향은 의존형보다는 독립형, 협동형 보다는 경쟁형, 회피형 보다는 참여형에서 긍정적으로 나타났으며, 성취도 측면에서 는 독립형, 경쟁형, 참여형에서 높게 나타났다. 또한 심층적 이해를 위해 학습자와 구조화된 면담을 실시한 결과 학습양식 유형별 프로그래밍 학습에 대한 요구사항의 차이를 알게 되었으며 교육환경, 학습교구, 학습내용, 교수방법 측면의 디키-3000 프로그래밍 교육 방안을 제시하였다.

The purpose of this study is to collect and analyze the student's pre-inquire and to obtain information on how to use the teaching-learning process. The specific research problem is to confirm the level of the student's pre-inquire, to identify the characteristics of each type, and to check what pre-inquire can be used in the teaching-learning process. The research was conducted on 149 children in the $3^{rd}$ and $4^{th}$ grade of elementary school, and collected a total of 2,034 inquires. As a result of analyzing three times, the students' pre-inquires accounted for 90% of Level 2 and Level 3, which are the inquires that give meaningful answers in the teaching-learning process. These results show that the pre-inquires presented before the students take up the new lesson are not low-level inquires and they can present meaningful inquires that can be used for teaching-learning. Next, as a result of analyzing the student's inquire by type, the factual question was the largest with 50%, followed by comprehension question, procedural question, application question, and prediction question. The factual and procedural questions showed that they could be used as learning activities during the teaching-learning process. Comprehension questions included in the wonderment question can be used as a learning question. And the application question is a question that can be applied to deepening activities, and the prediction question can be used in the inquiry and experiment process of learning activities.

The study aims to figure out pre-service elementary teachers' knowledge understanding on 'stratum and rock' as well as teaching-learning types on the same topic. A total of 65 seniors in an advanced science education course at B University of Education joined the research to fulfill the purpose above. With PCK classification framework, the study examined pre-service teachers' knowledge understanding on 'stratum and rock' while it analyzed how the teachers would teach the given topic to students. The results of the study are presented as follows. First, it was observed that the pre-service elementary teachers have a great understanding on 'stratum and rock' that would be taught via a science textbook for elementary fourth graders. However, regarding terms in 'shale and limestone', they appeared to have a relatively short understanding. Second, PCK elements of the pre-service teachers related to 'stratum and rock' were analyzed and according to the results, the teachers would be interested in teaching model selecting in the teaching-learning strategy field while they would be well aware of how important it is for them to perform an experiment in a teaching process. The teachers also appeared to understand that the teacher question can be mutual complementary during class. However, it turned out that the teachers would have a very much low understanding on learners' prior knowledge as they particularly believe that learning could be significantly affected by the learners' perception level as well as their learning interest and motive. Third, the pre-service elementary teachers were told to design teaching plans on 'stratum and rock' so that the study could find out what learning-teaching methods the teachers would adopt to teach the topic. It was learned that the teachers would proceed with the class basically by giving the learners a descriptive explanation on the topic and also by using pictures and drawings to enhance the learners' understanding during the class.
