The aim of this study is to provide basic data for college life adaptation support measures at the college level by identifying college life adaptation status, the relevance of university life adaptation and the core competencies. In order to ahieve this aim there are three objectives. This study is a research study to understand the relationship between college life adaptation and core competencies of college students before and after the coronavirus. The subject of this study was 171 university students from Seoul, Gyeonggi, and Honam. Data was collected through an untact questionnaire, and data analysis was performed using the SPSSWIN 25.0 program for mean, descriptive statistics, frequency analysis, T-test, correlation, and regression analysis. As a result, first, the difficulty of "emotional adaptation" before the coronavirus was high, and the difficulty of "academic adaptation" was high after the coronavirus. Second, the core competencies of college students were highest in the order of 'interpersonal relationship competency', 'problem solving competency', and 'information communication competency'. Third, as a result of analysis of the relationship between core competency factors and adaptation to university life, difficulties in social adaptation were found both before and after the coronavirus. After the corona, difficulties in adapting to school and learning new skills appeared. In conclusion, in order for university students to adapt to university life in the post-corona era, university-level support is needed to reinforce interpersonal relations competencies in unrect situations, reinforce information and communication competencies to promote academic adaptation, and reinforce new skills acquisition competencies.

A performance evaluation, which requires to observe students in the course of learning and studying and to evaluate their reports and materials, is emerging as an alternative evaluation method to overcome the shortcoming of simple written tests. However, there are many difficulties in real teaching setting to apply the performance evaluation, because it requires many burdens of efforts and time. In order to reduce these burdens of teachers, there have been several approaches which utilize the Internet for the evaluation. But these previous approaches have several limitations that they don't allow students' participation in evaluation activities, fail to provide a variety of evaluation methods. and/or support teachers' feedbacks very limitedly. In order to overcome these limitations. therefore. this paper designed and implemented a web- based performance evaluation system supporting the participation of students in doing evaluation themselves and various evaluation methods. which can be effectively managed by teachers. This web-based performance evaluation system developed in this paper can enhance not only students' high level thinking abilities but also their emotional and intellectual abilities. It can also help teachers to reduce the burden of working and the time in plenty used for evaluating students.

Collaboration and assistance among peer learners are essential factors for successful learning outcomes. However it is important to investigate students' preferences for computer problem solving methods and interrelationships, since students tend to solve problems more and more by themselves. This is because of the importance of giving appropriate instructions to students. In this context, this paper shows the analysis of the preferred methods and interrelationships of studnets' preferences upon encountering difficulties during computer usage by collecting data from 231 students in K national university of education. As a result, the result shows that students tend to solve problems without asking as they have higher abilities in computer usage, which was also shown to increase along with their grade levels. Furthermore, it showed that students who have family members and relatives, and who are using the internet are more satisfied with their problem solving. Lastly, it is possible to grasp the computer problem solving network within the department by using social network analysis, so it can be used as reference data for selecting the peer learners, which will help to operate the customized computer education practice.

The purpose of this study was to develop and apply three types SMART instructional modules about the mineral resources and investigate its effect. One hundred students in the experimental group and 111 students in the control group from 6 classes in the $1^{st}$ year of a girl's high school participated in this study. One unit of tablet PC was provided to every two students in the experimental group and three types of SMART classes were implemented in class. Teacher-centered traditional classes were carried out for the control group. The instrument designed to assess the level of students' interest in mineral resources consisted of 10 items using 5-point Likert scale. To investigate the level of students' understanding, 15 items were developed on the mineral, mineral deposits, and the development of mineral resources. In addition, the participants were asked to describe advantages and disadvantages of the classes using the SMART modules. Results are as follows. First, participants in the experimental group showed a significantly higher level of interest on the mineral and the mineral learning than those in the control group. However, there was no significant difference between the two groups in terms of the desire to observe minerals and rocks. Second, students in the experimental group showed a higher level of understanding than the control group. The students with higher learning ability showed a significantly higher level of understanding than the lower group students. Third, the participants pointed out that the advantage of the SMART instructional modules was their experience in searching the relevant information and producing diverse outputs about mineral resource. On the contrary, the difficulties in coordinating opinions and decision making due to the excessive quantity of information were perceived as the disadvantage.

This study aims to examine genetics problem-solving processes of high school students with different learning approaches. Two second graders in high school participated in a task that required solving the complicated pedigree problem. The participants had similar academic achievements in life science but one had a deep learning approach while the other had a surface learning approach. In order to analyze in depth the students' problem-solving processes, each student's problem-solving process was video-recorded, and each student conducted a think-aloud interview after solving the problem. Although students showed similar errors at the first trial in solving the problem, they showed different problem-solving process at the last trial. Student A who had a deep learning approach voluntarily solved the problem three times and demonstrated correct conceptual framing to the three constraints using rule-based reasoning in the last trial. Student A monitored the consistency between the data and her own pedigree, and reflected the problem-solving process in the check phase of the last trial in solving the problem. Student A's problem-solving process in the third trial resembled a successful problem-solving algorithm. However, student B who had a surface learning approach, involuntarily repeated solving the problem twice, and focused and used only part of the data due to her goal-oriented attitude to solve the problem in seeking for answers. Student B showed incorrect conceptual framing by memory-bank or arbitrary reasoning, and maintained her incorrect conceptual framing to the constraints in two problem-solving processes. These findings can help in understanding the problem-solving processes of students who have different learning approaches, allowing teachers to better support students with difficulties in accessing genetics problems.

The representation of irrational numbers has a key role in the learning of irrational numbers. However, transparent and finite representation of irrational numbers does not exist in school mathematics context. Therefore, many students have difficulties in understanding irrational numbers as an 'Object'. For this reason, this research explored how mathematics textbooks affected to students' understanding of irrational numbers in the view of process and object. Specifically we analyzed eight textbooks based on current curriculum and used framework based on previous research. In order to supplement the result derived from textbook analysis, we conducted questionnaires on 42 middle school students. The questions in the questionnaires were related to the representation and calculation of irrational numbers. As a result of this study, we found that mathematics textbooks develop contents in order of process-object, and using 'non repeating decimal', 'numbers cannot be represented as a quotient', 'numbers with the radical sign', 'number line' representation for irrational numbers. Students usually used a representation of non-repeating decimal, although, they used a representation of numbers with the radical sign when they operate irrational numbers. Consequently, we found that mathematics textbooks affect students to understand irrational numbers as a non-repeating irrational numbers, but mathematics textbooks have a limitation to conduce understanding of irrational numbers as an object.

Koreatech has adopted a long-term co-op program called IPP (Industry Professional Practice) to address problems in higher education of Korea since 2012, but it was anticipated to face many difficulties in implementing the program due to lack of relevant experiences in Korea. In this regard, a performance evaluation scheme was urgently required to judge the effectiveness of the Co-op program and improve the operational efficiency at the same time. This study aimed to develop comprehensive performance evaluation criteria for the co-op programs on the basis of Kirkpatrick's four-level performance evaluation model for training programs, and apply it to a real Co-op operation to test its feasibility. For this purpose, thorough review on the training program evaluation literature and in-depth analyses of overseas cases of co-op performance evaluation were conducted. Then, a set of Co-op performance evaluation criteria was developed and applied to the Koreatech's Co-op operation in 2013. Two Co-op student questionnaire surveys were administered before and after Co-op terms to measure students' reactions to the Co-op program (Level 1) and changes in participating students' attitudes and competencies (Level 2). In addition, employment rates of Co-op participating and non-participating students were compared (Level 4). The analysis findings showed that participating students were quite satisfied with their jobs and companies, and the Co-op program was effective to a certain degree at enhancing non-major competencies and attitudes to occupation of students. Together, the employment rate of Co-op participants, particularly in small- and medium-sized companies, grew significantly in comparison with that of non-participants. In the last part, several directions for improving the effectiveness of the Co-op programs were discussed.

As integrated essay writing is performed in university entrance examinations, teachers and students recognize the importance of integrated essay, but teachers have still difficulties of teaching methods. The purpose of this study is to derive educational implications through case of mathematics instruction for integrated essay education to pre-service mathematics teachers. The content knowledge of this class is a definition of conic section in mathematics and properties of conic section in an antenna reflector. The students have to discover them using the history of math, manipulative material, paper-folding and computer simulation. In this teaching and learning process the students can realize mathematical knowledge invented by humans through history of mathematics. The students can evaluate the validity of that as create and justify a mathematical proposition. Also, the students can explain the relation between them logically and descript cause or basis convincingly in the process of justifying. We should keep our study to instructional materials and teaching methods in integrated essay education.

The programming language is a core education area of software that is becoming increasingly important in the age of the fourth industrial revolution, but it requires mathematical knowledge and logical thinking skills, so that many local private university and college students with low basic skills are having difficulties learning it. This problem occasionally causes SW-major students to lose interest and confidence in their majors during the introductory course of programming languages; making them change their majors, or give up their studies. In this study, we designed an instructional model using Scratch for educating C-language which is a typical programming introductory language. To do this, we analyzed the concepts that can be trained by Scratch among the programming concepts supported by C-language, and developed the examples of Scratch for exercising the concepts. In addition, we designed an instructional model, by which the programming concepts are first learned through Scratch and then C-language is taught, and conducted an experiment on the SW-major freshman students of a local private university to verify the effectiveness of the model. In the situation where SW education is becoming common, we expect that this study will help programming language education of security IT students.
