The Korean government implemented better support for adolescent single-parent families by expanding the coverage of the Single-parent Family Support Act in 2010. In order to understand the effect, this study verified the moderating effect of the single-parent family policy's support for child rearing in the context of adolescent female single-parent's stress levels and education sustainability. This study utilized part of the National Youth Policy Institute's 'Research on the Actual Condition of the Adolescent Pregnancy, Birth and Rearing Children'. Participants of the study were 248 adolescent single-parents aged 24 and below. The findings and discussion of this study are as follows. First, the stress level of adolescent female single-parent in continuing studies was lower than those for discontinued studies. Students who discontinued their education in the middle of studies showed an increase in life stress level relative to age because they had a low level of education and had discontinued studies before pregnancy. Second, the public nanny service has been verified as an element to increase the continuation of education by controlling the level of stress. It is advisable to fortify and expand the scope of support for childcare services in the form of a study assistant or child education assistant. Last, adolescent single-parent childcare subsidies have been verified as a direct factor that raised the meaningful level of education continuity potential to a meaningful standard that can be seen as a more effective method than general policy support for single-parent families.

Video-demand learning through E-learning continuously increases on these days. However, not all video-demand learning systems can be utilized properly. When students study by education videos not matched to level of their own, it is possible for them to lose interest in learning. It causes to reduce the learning efficiency. In order to solve the problem, we need to develop a recommendation system which recommends customized education videos according the study levels of students. In this paper, we estimate the study level based on the history of students' watching behaviors such as average watching time, skipping and rewinding of videos. In the experimental section, we demonstrate our recommendation system using real students' video watching history to show that our system is feasible in a practical environment.

The benefits of teaching learning materials to others have been shown on learning achievement. Anxiety is one of the obstacles in learning and it has been shown that math anxiety is strongly associated with math achievement. Thus, the aim of this study was to investigate whether teaching others benefits math anxiety when university students learn statistics. 59 students who enrolled in statistics class participated and 30 students performed group assignment of teaching peer in a group and 29 students did not. Other than group assignments, the instructor, lectures, assignment of solving the problems, and exams were all the same. The results showed that the math anxiety of students who did group assignments of teaching was decreased at the end the semester. Increased math anxiety yielded negative attitudes toward learning statistics, resulting in poor learning performance. Furthermore, the relationship between math anxiety and the attitudes toward leaning statistics was moderated by teaching others. The results suggest that teaching others has an effect on reducing math anxiety and thus, possibly yield persistent learning gains.

This study was conducted to survey the learners' satisfaction with the online head and neck anatomy class and obtain basic data for the purpose of possibly making continuing online class educationally more effective. A Google Forms survey was conducted with dental hygiene students, and 120 copies of the questionnaire were used as data for the final analysis. The study surveyed when they take on online classes and the types of online classes and had the respondents subjectively evaluate their own understanding of the classes and their academic achievements through them. The biggest influence on learning immersion was academic achievement and the biggest influence on the satisfaction with online class was the students' understanding of the class. It is hoped that the research results will shed light on the directions for designing new curriculums in anatomy in this era of a pandemic.

In this study, we analyzed how information and technology education in elementary and middle school curriculum affects learning achievement of computational thinking courses in university. We conducted a questionnaire survey on students who took computer-related courses for the past year and collected data on what type of computer-related education they received. As a result of analyzing the data, students who received computer-related education in the previous curriculum showed higher overall academic achievement. However, there was a significant difference in learning achievement according to types of contents, and it is necessary to consider the design and improvement of efficient computational thinking education in the future through the results. It is also necessary to continue the analysis of the impact of the new education curriculum.

A 2(pedagogical agent: with vs. without) × 2(on-screen text: with vs. without) between-subject design was used in this study to investigate the effects of pedagogical agent and redundant on-screen text on video learning. In the case of the educational video without redundant on-screen text, there was no difference in social presence, satisfaction, and intention to continue learning regardless of the presence of a pedagogical agent. However, when the educational video contained redundant on-screen text, participants who watched educational video with pedagogical agent perceived higher social presence, satisfaction and intention to continue. In terms of academic achievement, no difference was found whether redundant on-screen text was contained or not. It supports some of the previous studies on the reverse-redundancy effects, suggesting that the inclusion of redundant text does not necessarily cause the reduction of learning outcomes. Video learning shows a higher dropout rate than face-to-face learning. Therefore, it is particularly important to understand how to strengthen interactions with learners and motivate them to keep themselves engaged in learning. This study discussed whether pedagogical agent and on-screen text are factors that induce continuous participation of learners in video learning.

This study aims to explore a learning progression for eight core concepts of middle school science using constructed response items in the national assessment of educational achievement (NAEA). For this purpose, a total of 7,390 responses of the 9th graders on 8 constructed response items in NAEA conducted in 2015 were inputted by computer and the inputted answers were analyzed and classified into different levels. After completing this process, five levels were set for each construct and a construct map was created according to the levels. In this study, the construct map was written in a progression-based rubric format, which was used as a criterion for leveling the answers of all students. In addition, the Rasch model was applied to measure the scores and achievements of the respondents by means of statistical analysis to correlate the scores of the students with the achievement levels of the constructs. Lastly, a preliminary learning progression was created by revising the construct map reflecting the results of Rasch model application. This study was meaningful in that it explored the possibility of developing the learning process by using constructed response items in NAEA. However, the preliminary learning progression developed in this study is still hypothetical and inferential because it is not longitudinally traced to individual students. Therefore, it is necessary to continually revise and supplement through iterative research process.

This research is designed to review the systems thinking and STEAM theory while ascertaining the effects of the classroom application of the STEAM programs based on systems thinking appropriate for studying climate change. The systems thinking based STEAM program has been developed by researchers and experts, who had participated in expert meetings in a continued manner. The program was applied to science classes over the course of eight weeks. Therefore, the application effects of the systems thinking based STEAM program were analyzed in students' systems thinking, STEAM semantics survey, and students' academic achievement. The findings are as follows. First, the test group has shown a statistically meaningful difference in the systems thinking analysis compared to the control group in the four subcategories of 'Systems Analysis', 'Personal Mastery', 'Shared Vision' and 'Team Learning' except for 'Mental Model'. Second, in the pre- and post-knowledge tests, the independent sample t-test results in the areas of science, technology, engineering, art and mathematics show statistically meaningful differences compared to the control group. Third, in the academic performance test regarding climate change, the test group displayed higher achievement than the control group. In conclusion, the system-based STEAM program is considered appropriate to enhance amalgamative thinking skills based on systems thinking. In addition, the program is expected to improve creative thinking and problem-solving abilities by offering new ideas based on climate change science.
