Gender differences have been given major attention in mathematics education in the context of pursuing gender equity in instructional and learning environment. It had been traditional belief that male students would outperform female students in mathematics, especially in the areas as geometry. This belief has been given doubts by cumulated empirical evidences that gender differences are gradually diminishing or even reversing its direction as time goes on. In this study, gender differences in geometry were explored using TIMSS 8th grade mathematics data administered in TIMSS 2003, 2007, and 2011, based on a cognitive diagnostic modeling(CDM) approach. Among various CDM models, the Fusion model was employed. The Fusion model has advantages over other CDM models in that it provides more detailed information about gender differences at the attribute level as well as item level and more mathematically tractable. The findings of this study show that Attribute 3(Three-dimensional Geometric Shapes) revealed statistically significant gender differences favoring male students in TIMSS 2003 and 2007, but did not show significant differences in TIMSS 2011, which provides an additional empirical evidence supporting the recent observation that gender gap is narrowing. In addition to the general trends in gender differences in geometry, this study also provided affluent information such as gender differences in attribute mastery profiles and gender differences in relative contributions of each attribute in solving a particular item. Based on the findings of the CDM approach exploring gender differences, instructional implications in geometry education are discussed.

The purpose of this study is to seek a measure to institutionalize the curriculum of Korean homeschooling by comparing and analyzing curriculums of homeschooling between the United States and South Korea. To do so, literature review was conducted to derive analysis criterion and curriculums of homeschooling between the United States and South Korea were compared and analyzed. The major findings of analyses are as follows. First, from the perspective of educational goal, homeschooling families of both countries are similar in which they preferentially seek private goal but also consider social goal as well. Second, in the perspective of educational content, a diversity in course of study, textbook and other education materials of homeschooling in the United States is substantially attained when Korean homeschooling families suffer shortage. Third, in terms of educational implementation, homeschooling of both countries attained an autonomy in instructional time and a diversity in instructional space and method, however, unlike homeschooling in the United States, homeschooling in South Korea is experiencing difficulties due to lack of homschooling organization, homeschooling co-ops and web-site space. Fourth, in the perspective of educational evaluation, homeschooling in South Korea, unlike its comparison target, has not been certified as a formal education as well as not been accepted from universities. Based on these analysis results, conclusion and discussion have been proposed.

Non-Contact society has arrived due to social distinctions by COVID 19 pandemic. The arrival of the era of non-contact is having a profound impact on educational activities as well as on our social and economic lives. In response to the pandemic situation universities and all other educational institutions have implemented non-contact online classes. In particular arts physical educations and other practical classes are experiencing many difficulties due to the limited environment caused by social distancing from COVID 19 pandemic. Vocal classes are undergoing a transition mainly from 1:1 individual face-to-face lessons or group teaching methods to the non-contact era of online teaching or lesson methods. It is necessary to look at the direction of non-face-to-face practical classes in preparation for accelerated educational innovation. Edu-tech, which innovates technology in the wake of the age of non-contact after COVID 19 pandemic is expected to begin in earnest at school sites in Korea which have remained in the traditional way of education. The purpose of this study is to effectively non-contact vocal instructional methods by cogitating the current state of higher practical education and vocal classes in Korea. In addition, This study conducted two components of satisfied instructions such as 'Priorlearning of monitoring of recorded singing', and 'Immediate analyzing of various vocal contents and supplementary lessons of music theory' with a research on the peos and cons of non-face-to-face vocal class. Over a period of time, The effective non-contact of vocal instructional methods is in need to supplement non-face-to-face vocal class problems and further research and system construction with non-face-to-face vocal class's pros and cons to construct high-quality lecture contents is warranted.

Purpose : This is a study on the actual state of instructing in cardiopulmonary resuscitation(CPR) in hospitals, so lays its purpose on providing basic materials for instructing in CPR by understanding the actual state of instruction in CPR for paramedics or first aide persons in hospitals. Result : 1. As a result of examining the actual state of instruction in CPR operation during the past 3 months, 89.3% of the subjects answered that they receive regular instruction. 2. As the number of CPR instruction during one year, the majority of them, 96.0% answered that they have instruction more than one time a year. 3. As answers to their desired first-aid instruction to receive by allowing duplicated responses with 4 items, instruction in CPR and respiratory obstruction for adults was 18.2% occupying the highest proportion followed by instruction in first-aide treatment for traumas with 17.7% and in how to use the AED with 16.3%. Suggestion : First, it is thought that instruction in CPR should be conducted on a continuous basis and the number of instruction should increase. Second, one should provide first-aide persons with proper instruction in CPR operation by developing time tables and protocols for instructional programs, and also make it possible that they can learn various skills by increasing the number of instruction.

The purpose of the study is to identify the point of knowing. The point of knowing is the time, which indicates that 'knowing' occurs in the recognition process. To understand recognition process, the researchers analyzed the questions in units of lessons presented in elementary mathematics textbooks. The researchers analyzed the validity of the point of knowing and found out the basis of the point of knowing. The results are as follows. First, the point of knowing is time to expect to change from a leaner's 'not-knowing' to 'knowing'. Second, the point of knowing can be identified with the questions on textbooks to ask students to do practical action. Third, the point of knowing is closely related to instructional objective in a class. Fourth, in relation to subsidiary awareness and focal awareness, the point of knowing corresponds to focal awareness. Fifth, the point of knowing is equivalent to the inflection point at which personalization/contextualization is changed into depersonalization/decontextualization.

The purpose of this paper is to compare and analyze TOEIC scores of two kinds of courses opened at a university and the distribution of TOEIC scores of two groups. In addition, this paper will examine the ability of participants and the used instructional materials and equipment. The university has two kinds of TOEIC courses; one is a four-week intensive course opened in summer and winter vacations, where students participate in the classes from 9:00 a.m. to 4:00 p.m. The other is a regular TOEIC course, offering one-hour class every day from Monday to Friday during the university semester (15 weeks). This paper points out how important, the EFL/ESL teacher education, teaching materials, teaching methods and e-learning in operating more effective classes. The intensive TOEIC course and the regular TOEIC course include 120 hours and 75 hours a semester, respectively. Unfortunately, both courses have such a limited amount of time that students cannot achieve their fluent and perfect command of English. For Korean student to master English in a limited amount of both time and resources, the development of effective and qualitative EFL/ESL Intensive courses is essential.
