The ultimate goal of instruction is for learners to understand contents they have to learn in class. Therefore, shedding light is needed on the characteristics of understanding required by teachers and perceived by students when class is conducted for the purpose of understanding. To do this, 87 middle school teachers were requested to write down questions they asked to improve the understanding of learners in 'reproduction and genesis' unit. They were categorized according to Wiggins & McTighe's six aspects of understanding and a questionnaire was developed based on the data. A survey was conducted on 90 teachers and 370 ninth-grade students. The findings of this study were as follows: First, the teachers demanded explaining, interpreting and perspective a lot, but applying, empathy and self-knowledge were scarcely required. Second, the teachers demanded explaining the most, and the students as well. The next aspect of understanding in both groups was interpreting, followed by perspective, applying, empathy and self-knowledge. There were significant differences among the opinions of the students according to gender (p<0.05). Third, the students persevered explaining, applying and self-knowledge the same way as the teachers demanded, but not for interpreting, perspective and empathy. This study is expected to provide some information to achieve the instruction objectives of understanding successfully.

Operating Systems is a discipline which handles abstract concepts and techniques. However, most of OS courses have been textbook-oriented theoretical classes. Theoretical classes lead to the decline in the understanding of a lecture, and hurt their concentration. Many instructors have tried to make use of educational tools to help students understand lectures and arouse interests. This paper describes the design and implementation of a CPU scheduling simulator which shows the operation of process scheduling algorithms visually. The academic achievement evaluation for 2010's students and 2011's and t-test results show that the differences of the correct answer ratio for the exam about CPU scheduling algorithms are meaningful. The survey shows that the simulator is useful as an educational tool which causes the interests and enhances the understanding of a lecture, this teaching method is effective to develop problem solving skills.

The effects of computer-assisted instruction (CAl) using molecular-level animation and worksheet upon students' achievement, conceptual understanding, and learning motivation were investigated. Treatment and control groups (2 classes) were selected from a girls' high school in Seoul, and taught about dissolution for 3 class hours. Before the instructions, the Patterns of Adaptive Learning Survey (PALS) was administered, and the grade for a previous science course was obtained. The PALS score was used as a covariate, and the other as a blocking variable. After the instructions, the achievement test, the conceptions test, and the Instructional Materials Motivation Scale (lMMS) were administered. Two-way ANCOVA results revealed that the scores of the CAl group in the achievement and the conceptions tests were significantly higher than those of the control group. The CAl group also performed better in all subtests of the IMMS except the subtest of relevance.

This study analyzed student noticing in a lesson that emphasized relational understanding of equal signs for first graders from four aspects: centers of focus, focusing interactions, mathematical tasks, and nature of the mathematical activity. Specifically, the instructional factors that emphasize the relational understanding of equal signs derived from previous research were applied to a first-grade addition and subtraction unit, and then lessons emphasizing the relational understanding of equal signs were conducted. Students' noticing in this lesson was comprehensively analyzed using the focusing framework proposed in the previous study. The results showed that in real classroom contexts centers of focus is affected by the structure of the equation and the form of the task, teacher-student interactions, and normed practices. In particular, we found specific teacher-student interactions, such as emphasizing the meaning of the equals sign or using examples, that helped students recognize the equals sign relationally. We also found that students' noticing of the equation affects reasoning about equation, such as being able to reason about the equation relationally if they focuse on two quantities of the same size or the relationship between both sides. These findings have implications for teaching methods of equal sign.

Science class is the starting point of science education where science teacher and students meet together to teach and learn science. Therefore successful science class is the main concern of various educational partakers, such as teachers, students, parents, school administrators, and science education researchers. In order to find what is important among the teaching abilities of science teachers, a survey was conducted to the various educational partakers. As the result of survey, students chose 'progressing a lesson' and 'teacher's attitude' are important, and in-service teachers chose 'analyzing learner characteristics and curriculum' and 'teacher-student interaction' are important, while the pre-service teachers and parents chose 'teacher-student interaction' and 'progressing a lesson' are important. In addition, the school administrators chose 'setting up teaching-learning strategy' and science education researchers chose 'understanding curriculum and developing teaching-learning method' is important along with 'analyzing learner characteristics and curriculum.' In the communication on science education among different educational partakers, these result can be used as the basic information to understand the different perspectives on a science class.

As a tool of programming education, a robot is effective in creative problem solving abilities and logical thinking skills. It also provides practical, operational learning experience to learners, when using as a tool of learning, it can help learners' specific understanding for the contents of education and lead to an active participation in learning. This research focuses on the robot's instrumental use in the mathematics class. So the lesson activities with relation to the fourth grade math curriculum were developed after the functional analysis of the robot and the extraction of educational utilization with function. The result shows that there wasn't a significant difference in achievement test but there was a positive response in the most of the survey items. It shows that robots lead to an active participation in class, to be interested in math class and were helpful to understand math concepts. There was also a positive response in the result of learner interviews such as dynamic, collaborative communication, experiential, practical lessons that are rare sights in normal math class.

The purpose of this study is to analyze Korean college students' perceptions of interactions and senses of community, among students, and instructors and students as they took face-to-face classes by the time students and instructors came back to the classroom. Forty-nine college students participated in the study, and all of them had experienced non-face-to-face classes during the last two years from 2020 through 2021. They responded to the revised Rovai (2002)'s Classroom Community Scale (CCS), and the data were analyzed using a frequency analysis. The findings of data analysis showed that the students positively perceived the class contents and teaching formats of face-to-face classes, in terms of understanding and concentration on the class. On the other hand, it was found out that the students would still need more time for being familiar with face-to-face classes, and their affective variables of the educational environment should be considered.

This convergence study was conducted to identify the effect of the awareness enhancing program of the international development cooperation of college students sponsored by the Korea International Cooperation Agency (KOICA). A quasi-experimental study design was used. The participants consisted of one experimental group (n=32) who attended the awareness enhancing class of international development cooperation and the other control group (n=32) who did not participate in the class in a university in C city. The data were collected using online survey before the first class and after the last class in spring semester 2019. Collected data were analyzed by ANCOVA using SPSS WIN Version 20.0 program. The levels of global citizenship (p=.003) and career preparation behavior (p=.013) was higher in the experimental group than in the control group. However, career identity(p=.385) and cooperative efficacy(p=.488) did not show significant difference between the groups. This study proposed the direction for the awareness enhancing program of the international development cooperation of college students by showing its positive effects on the global citizenship and career preparation behavior.

The purpose of this study was to develop a program for the history of science and technology in order for the technical high school students to understand the nature of science (NOS). The program was composed of the six topics based on the textbooks such as convergence science and physics I, and was taught to 290 10th graders at a technical high school located in the metropolitan area. The questionnaire about NOS was asked the students before and after the instruction, so as to investigate the effect of the program on improving their understandings of NOS. The analysis followed t-test and ANOVA using SPSS 23.0 for Windows program. The questionnaire based on the conceptual framework of the four themes of the NOS (Lee, 2014). The research findings were as follows. First, the program was effective in improving their understanding of NOS since the t-test result was significant statistically for the overall domains of NOS (p<.01). Second, there was no significant gender differences in the understanding of NOS among technical high school students (p<.05), neither did their majors (p<.05). Third, all domains in NOS were statistically correlated (p<.01), and in a particular, each domain was consistently correlated with the aspect of the nature of the interactions among science, technology, and society. Hence, the further studies should be conducted to examine how the history of science and technology effects the understanding of the NOS and how the domains in NOS affected each other.
