Problem-based learning (PBL) is applied to various subjects for the sake of learners' creative thinking, problem-solving skills, presentation skills, confidence, self-directed learning, cooperation, and for the communication skills required in a rapidly changing society. Among them, the English language-an official language-is invested in 2.3 times more than other subjects, according to the English education company Yoon's Teacher. Therefore, PBL is an important learning method. However, the reality is that teacher-centered instruction, acquiring knowledge of the best answers only, and traditional evaluations are the main subjects. In order to supplement these weak points, this study designed a learning model for English subjects based on Barrows & Myers (2002) and the analyze, design, develop, implement, and evaluate (ADDIE) model. As a result of a PBL English class based on the ADDIE model, the learners were able to improve their presentation skills by 86%, their interest in learning by 86%, their understanding of learning by 86%, and cooperation by 100%. As such, studies on designing the learning model should be carried out continuously to achieve the purpose of 21st century English education, which is to improve learners' communication skills and information processing skills.

Ameliorating mechanisms of red ginseng on learning deficits were investigated in the following 3 experiments; its effects on 1) place learning deficits in aged rats and in young rats with selective hippocampal lesions (behavioral study), 2) long-term potentiation in the hippocampal formation (neuro- physiological study), and 3) ChAT (choline acetyl transferase) activity in various brain regions of aged rats (pharmacological study). In the behavioral study, first, performance in the place learning tasks were compared among 3 groups of young and aged rats; control young intact rats (10-12 week old) treated with water, aged rats (28-32 month old) treated with water, and aged rats (28-32 month old) treated with red ginseng (100 mghglday) suspended in water. Second, performance in the place learning tasks was compared among 3 groups of young rats; control intact rats treated with water, rats with bilateral hippocampal lesions treated with water, and rats with bilateral hippocampal lesions treated with red ginseng (100 mg/kg/day). Each rat in these 2 behavioral experiments was tested with the 3 types of the place learning tasks in a circular open field using intracranial self-stimulation (ICSS) as reward. The ICSS reward was delivered if the rat (1) moved distance of 100-160 cm (DMT): (2) entered an experiment-determined reward place within the open field, and this place was randomly varied in sequential trials (RRPST); or (3) entered 2 specific places, and did a shuttle behavior between the 2 places (PLT). Performance of the aged rats in the ginseng group was not significantly different from that of control young rats in ICSS (current intensity, bar press rates), DMT and RRPST. However, treatment with red ginseng significantly ameliorated place-navigation learning deficits in aged rats in the PLT. Similarly, red ginseng ameliorated learning and memory deficits in young rats with hippocampal lesions in the same tasks. In the neurophysiological study using young rats, perfusion of hippocampal slices with non-sapon in fraction of red ginseng significantly enhanced magnitudes of the long-term potentiation (LfP) in the CA3 subfield. In the pharmacological study, treatment with red ginseng did not affect ChAT activity in aged rat brain including the hippocampal formation. These results strongly suggest that red ginseng ameliorates learning and memory deficits in aged rats through actions on the CA3 subfield of the hippocampal formation, which were independent of the presynaptic components of the cholinergic system

The purpose of this study was to explore ways to help reduce adolescents' academic stress by exploring the influences of parental learning involvement and family strengths on academic stress. The research participants were 445 middle school students living in Gwangju. Data were collected from self-reported questionnaires and analyzed with SPSS 23.0 program. The major findings were as follows: First, the parental learning involvement(provision of learning option, democratic rules, encouragement of academic progress) and academic stress showed significant differences according to gender. There was a significant difference in academic stress depending on school year, but there was no significant difference in parental learning involvement. The family strengths did not show significant difference according to gender or school year. The parental learning involvement(provision of learning option, democratic rules, pursuit of adequate performance, academic information, total), family strengths, and academic stress showed significant differences according to economic status. Second, the adolescents' academic stress was influenced by parental learning involvement(encouragement of academic progress, democratic rules, pursuit of adequate performance) and family strengths. Approximately 30 percent of the adolescents' academic stress was explained by these variables.

The purpose of this study is to develop a mobile-based math learning application and explore its application. In order to develop a learning application, the present study included literature review on math education involving mobile learning, investigation of literature related to mathematics education conducted in a digital environment, and method of use and implementation environment of existing math learning applications by type. Based on these preliminary investigation and analysis, an android version application, 'Mathematics Classroom for Middle School 3rd Graders' was developed. This application can be used for learning units such as Quadratic Functions and Graphs, Representative Value, and Variance and Standard Deviation. For the unit on Quadratic Functions and Graphs, the application was constructed so that students can draw various graphs by using the graphic mode and discuss their work with other students in the chatting room. For the unit on Representative Value, the application was constructed with the mathematical concept of representative value explained through animation along with activities of grouping data acquired after playing archery games by points or arranging them according to size so that students can study when and how to use median value, mode, and average. The application for Variance and Standard Deviation unit was also constructed in a way that allowed students to study the concept of variance and standard deviation and solve the problems on their own. The results of this study can be used as teaching & learning materials customized for individual student in math classes and will provide anyone the opportunity to engage in an interesting self-directed learning of math at anytime. Developed in the format of real life study, the application will contribute to helping students develop a positive attitude about math.

The lecture is the main method of teaching, and the most common activity of students is 'listening.' Therefore, efficient and positive changes are expected if the researcher analyzes and uses students' listening styles to educate them. In addition, as the learner-centered education is emphasized, the learner's characteristics are becoming more important, and this flow increases the value of the listening styles of the student and that of the learning strategy, which is the student's self-directed learning. Therefore, this study examined whether there are differences in science achievement according to the listening styles and learning strategies by statistical analysis of the data obtained by conducting surveys for students in 5th, 7th, and 10th grades. The results of this study are as follows: First, students' listening styles and learning strategies show significant differences between men and women. Second, students' listening styles and learning strategies show significant differences between grade levels. Third, the level of task-oriented and critical listening types among listening styles produce meaningful differences in science achievement. Fourth, listening style, learning strategy, and science achievement have a significant correlation with each other. Finally, in terms of learning strategy-science achievement, it was shown that basic and complex cognitive strategy had a positive correlation with science achievement.
