Using TIMSS survey data, we analyzed whether there were any significant changes in the learning environment of middle school science classes over the last 10 years. Our study selected questions from teachers and school principals' questionnaires and divided them by category: science class, teacher professional development, and school environment. The science class components were subdivided into three categories: science learning activities, evaluation, and homework. Within teacher professional development, the sub-categories included teacher training, collaboration to improve teaching, and teacher evaluation. School environment subdivided into two aspects, these being school characteristics and school system. Our research confirmed that there has been a positive change overall in learning environments. However, most classes are teacher-conducted and also teacher-oriented; the proportion of science investigation activities has declined compared against the prior ten years. Our study show that students do not engage in a range of inquiry-related activities. The questions on tests and examinations involve mostly knowledge application and understanding, although recent methods of evaluation show improvement. As for the science teachers, they participate in many professional development programs but focus on science content, science curriculum, and pedagogy. In addition, teachers do not have many opportunities to participate in the training to integrate information technology into science, science assessment, or improving students' critical thinking or inquiry skills. The teachers are satisfied with their profession, and the shortage of science resources does not seem to affect instruction.

Objectives: Handwashing is one of the most effective methods to prevent the spread of infectious diseases. This study assessed the related factors and reasons for not practicing handwashing at school among adolescents. Methods: We analyzed data collected from 57,303 adolescents who participated in the 15th Korea Youth Risk Behavior Survey 2019. Results: The proportions of not washing hands "before meals at school" and "after using the toilet at school" were 15.9% and 4.4%, respectively. The adjusted odds ratio for not washing hands before meals at school was significantly higher in girls (Odds Ratio [OR]=1.52, 95% Confidence Intervals [CI]=1.42-1.63), metropolitan city (OR=1.32, 95% CI=1.11-1.56), city (OR=1.29, 95% CI=1.08-1.54), higher grade, higher academic performance, lower economic status, not handwashing at home (OR=14.36, 95% CI=13.37-15.42), and without annual personal hygiene education (OR=1.41, 95% CI=1.33-1.49). Reasons for not washing hands at school among adolescents who do not wash their hands before meals at school included 'it is bothersome (52.3%)', 'there is no soap or hand sanitizer (13.8%)', and 'I do not feel the need (9.5%)'. Conclusions: Improving handwashing before meals at school among adolescents requires raising awareness of the importance of handwashing before meals and establishing a suitable environment and handwashing-encouraging culture.

One of the most popular keywords in 21th century is "Information Society". Information Society improves the overall quality of human life, but increases the negative aspects such as internet addiction and digital divide. The purpose of this study is to understand the vicious cycle between socio-economic disparities and digital divide. This study analyzed the effects of poverty on school maladjustment and academic achievement and mediation effects by using parental monitoring and internet use types as mediators. Data were obtained from the Korea Youth Panel Survey(KYPS). Structural equation modeling was employed for statistical analyses. The result showed that poverty reduced parental monitoring and information-oriented type of internet use. Youth who used less information-oriented type showed more school maladjustment and less academic achievement. However, the relationship between poverty and entertainment-oriented type was non-significant. Thus, parental monitoring and the internet use types were one of the main pathways which can affect school maladjustment and academic achievement among youth in poverty. There was the possible vicious cycle between poverty and digital divide. Based on this study, we strongly suggest improvement of the media competence to solve the problem of digital divide among youth in poverty.

The purpose of this study is to explore ways to secure highschool students' choice of courses in order to improve highschool - university linkage. For this purpose, we conducted in-depth focus group interviews with a total of 10 students in the second or the third year or graduate student at the science and engineering college, and these interviewees were recommended by their professors. Through interviews, the necessity to complete highschool science prerequisite courses, reason for not completing highschool science prerequisite courses necessary for college major, their intention to recommend highschool juniors to complete science prerequisite courses, and ways to guarantee prerequisite course completion for college major studies. Based on the results, we suggested ways to link highschool - university curriculum for science & engineering majors. Discussed in the conclusion are ways to stabilize highschool curriculum organization and implementation such as opening elective courses with a few students without disadvantage in the school record, improving the grading system for Science II courses in the school record as well as the College Scholastic Ability Test, providing career guidance about prerequisite courses by science & engineering majors, improving the science teacher's professionalism on teaching and career guidance, and developing college entrance systems to guarantee the completion of prerequisite courses for science & engineering college studies.

Purpose: This study examined the frequency of sugar-sweetened beverage consumption in Korean adolescents and the major factors influencing the excessive consumption of sugar-sweetened beverages, such as sociodemographic characteristics, health-related behaviors, psychological characteristics, and dietary habits. Methods: The analysis was performed using the data from the 2017 Korean Youth Risk Behavior Web-based Survey. The subjects included in the analysis were 30,885 middle school students and 31,391 high school students, totaling 62,276. The frequency of sugar-sweetened beverage consumption was calculated by summing the consumption frequencies of soda, high caffeine or energy drinks, and sweet beverages over the last 7 days. The Rao-Scott chi-square test, reflecting information on the sampling design, was used to test the differences in the rate of sugar-sweetened beverage consumption according to each factor. Logistic regression analysis was performed to examine the factors influencing the excessive consumption of sugar-sweetened beverages. Results: The rate of sweetened beverage consumption was higher in boys than in girls, in high school students than in middle school students, in students whose father's education level was lower, in those whose subjective academic performance was lower, and in those who smoked or consumed alcohol. In addition, the rate of sugar-sweetened beverage consumption was higher in those who experienced severe stress, suicidal ideation, sadness, or a sense of despair. The rate of sugar-sweetened beverage consumption was also high in those who skipped breakfast; who frequently consumed fast foods, ramen, or snacks; and who frequently ate meals at convenience stores, supermarkets, or school stores. Conclusion: The rate of sugar-sweetened beverage consumption in Korean adolescents is related to various factors, such as sociodemographic characteristics, health-related behaviors, psychological characteristics, and dietary habits.

In this paper, we analyzed the freshmen's achievements on general mathematics their GPA based on 'basic mathematics diagonal test score' among college entrance types in natural science or engineering. Also, we studied the achievements of students who were not passed the 'Basic Mathematics Diagonal Test (BMDT)' and had to take supplementary lessons to improve their mathematics abilities four times a week during the first semester of academic year 2012 in Mokpo National University. We found the followings; first, freshmen were accepted by the university through the regular admission have a higher level of academic achievement compared other type admission. Second, freshmen's academic achievement in the first semester has significant meaningful effect on their academic achievement in the second semester. Finally, there are correlations between achievements of general mathematics and a curriculum of freshmen who were passed test after taking supplementary lessons.

The authors studied on anxiety, using Zung's self-rating anxiety scale (SAS), on the subjects of 329 men and 522 women of 60 years old and older. This study was carried out for 8 months from November 1983 to June 1984 in the area of Seoul, Taegu and Kyungsan Gun, Kyungpook province. The results showed that there was no significant difference in the means of total anxiety scores between the two groups of men and women. The anxiety scores in items of sweating, apprehension, dyspnea, restlessness and insomnia were relatively high in both groups. The scores of faintness, panic, fear, tremor and facial flushing were low in both groups. Among 329 men, 48(14.6%) showed rather serious anxiety level of score 50 or higher, while 153 of 522 women (29.4%) showed the same score. Among these psychosocial factors, suppoter, living place, religion and security system are significantly related with anxiety scores in both groups (p<0.01).

The purpose of this study was to examine the effects of the game application learning 8th graders' scientific attitude, which was utilized as a strategy to improve the teaching skills and methods in the lesson of 'the history of the earth and diastrophism'. The subjects of this study were 120 students of 8th grade at a middle school located in a metropolitan city in Korea. To start off with homogeneity of a group, this study recruited participants by the results of a diagnostic test taken early in the year and a mid-term examination taken at the end of April. As a result, a total of 4 male classes that showed similar results on the two tests were selected and divided into two groups: one in experimental and the other in control. In addition, the top 20% students and the low 20% students were chosen for comparison of their scientific attitudes based on the results of the mid-term examination. The traditional teachings were offered to the control groups while the experimental lessons with the game activities performed at the stages of application and summary in teaching were offered to the experimental groups over 10 periods. Results of the pre- and post-test on the students' scientific attitude demonstrated that there was a statistical significance between the two groups, which suggested that the experimental group showed a meaningful improvement in the scientific attitude after experimental intervention lesson activities with game applications. Also, the more meaningful improvement in the scientific attitude was found in the lower group than in the higher group. It implies that lessons with the game activities motivated the students to voluntarily participate in school science learning by enhancing their interests. Therefore, it is suggested that game application learning be a new teaching-learning material that helps to encourage learners to actively participate in middle school science learning.

In order to explore the learning attitude of the learners and the effects of conscious learning attitudes on academic achievement in On-line education system of open high school, we analyze the log data of 2,965 first graders who studied English, Math, Integrated Society and Integrated Science during the first semester of 2018. This study examines the learning status according to the learner's background variables, and analyzes the number of lessons per hour, learning progress rate, learning period, learning start month, and formative evaluation results for each class. In addition, to verify the effects of conscious learning attitude on academic achievement, skewness and kurtosis are calculated by using learning frequency values for each class. As a result, in almost all fields, the average number of lessons per class, study duration, progress rate, and grades, women are higher than men. In addition, the older ones are, the higher they are and the Seoul area is higher than the other area. The average learning period is 2~3 months, and the longer the learning period, the higher the formative evaluation score. Lastly, even though the number of learning is lower than that of learners who concentrate on a certain period of time, the formation scores of learners who learn consciously are higher.
