The purpose of this study was to develop and apply a differentiated instruction-learning reflecting various characteristics and demands of the gifted underachievers, and thereby help to develop the study attitude and study achievement of the gifted underachievers. To achieve the purpose, a case study on five gifted underachievers who are in $6^{th}$ grade of elementary school was conducted. By collecting and analyzing a variety of data including standardized tests, interviews with teachers, students, and parents, and observation journals, this researcher examined the characteristics and demands of the gifted underachievers. For the development of the program, differentiated strategies were designed according to students' interest and concern, their multiple-intelligence, and their learning styles. As a result of the application of them, a program with a total of 20 sections was finally developed. The result of the application for the differentiated instruction-learning program revealed improvements in their academic achievements. In addition, it was found that their learning motives were improved. The program was also found to affect their self-concept and their attitude toward learning. The study showed that developing an education program for the gifted underachievers should begin from the analysis of each student's characteristics. Also, it was found that a differentiation strategy could become an alternative to apply various characteristics and demands of the gifted underachievers to the development of a program. The gifted underachievers' intellectual and definitive characteristics were changed even by the short-term mediation. Therefore, the new issue about educating the gifted is to provide a differentiated instruction-learning program fitting their characteristics and demands and help them exert their potential as best as they could.

There have been a lot of studies on problem based instruction and collaborative learning environment, but there is a lack of the studies on a system that offers a collaborative learning environment for problem based instruction. Thus I developed and applied a collaborative instruction system for web based problem based instruction. The system was comprised of the collaborative instruction room and the problem based instruction room so that the students could solve the problems by groups through collaborative instruction. The developed system was applied to the actual learning. As a result, the system contributed to the students' improvement in academic achievements, drew a high degree of responses from them, and had positive effects on their affective domain.

The future society will be identify various problem situations accurately and the ability to solve problems effectively using computing technology become more important. Based on this background, an education of future human resources based on computational thinking as well as a problem-solving ability are important in university education. Therefore, in this paper, we have analyzed the effects of software education to improve computational thinking based on problem-solving learning. We have found that there is a significant difference between the interest of the students and their learning and academic achievements. Therefore, based on the understanding of the learning motivation and method, if the problem-solving learning is conducted in real-life scenarios suitable for the level of the student, it can be possible to induce the interest of the students and improve their computational thinking ability.

It is well-known that every learner has his/her own learning style and the learning style has a great effect on his/her learning characteristics, processes and achievements. This study aims to induce some implications for designing the gifted mathematics programs which go with gifted students' learning styles. To do this, we applied the gifted mathematics program of nine lessons to 52 third grade gifted students and examined the characteristics of the programs according Kolb's learning style. To investigate the effect of the program, the pretest and posttest for applying the programs were taken and the results of two tests were analysed by t-test. As a result, the students of diverging style increased and the ones of converging style decreased, while there is little change in the accommodating style and the assimilating style. It was also shown that the average of the concrete experience(CE) of the subjects has increased significantly. This study also contains some pedagogical implications based on discussing about the results of analysis.

Compressed Sensing(CS) deals with linear inverse problems. The theoretical results of CS have had an impact on inference problems and presented amazing research achievements in the related fields including signal processing and information theory. However, in order for CS to be applied in practical environments, there are two significant challenges to be solved. One is to guarantee in real time recovery of CS signals, and the other is that the signals have to be sparse. To this end, the latest researches using deep learning technology have emerged. In this paper, we consider CS problems based on deep learning and discuss the latest research results. And the approaches for CS signal reconstruction using deep learning show superior results in terms of recovery time and performance. It is expected that the approaches for CS reconstruction using deep learning shown in recent studies can not only raise the possibility of utilization of CS, but also be highly exploited in the fields of signal processing and communication areas.

Adult-learners of online education have been distant from studying for a long time and are rather familiar with the old massive education. As a result, despite the excellent ability in self-control learning that results in great academic performances and academic continuity, the learners give up on learning, feeling depressed for not being able to perform their advantage, the self-control learning ability. The study developed a self-control learning model and UDL design learning model in order to establish e-mentoring system. For the analysis on results of the experiment, the researcher extracted academic grade, the rate of re-register, and the amount of total studying time after dividing new students and transfer students of H cyber university into the control group and the experimental group. In conclusion, the results showed that more satisfied the control group is, the higher academic achievements and the higher academic continuity are accomplished.

Elementary mathematics education in the 7th mathematics curricula has been emphasized to foster ‘mathematical power’. For establishing this purpose, we need to provide the opportunities inducing to students' thoughts and to study leaching-learning methods to make structuring for their thinking process. Using to writing activities in students' mathematics learning, we think that we can find out their thinking process and this writing mathematics learning method is effective to promote their communication. Through analysing to six grade mathematics textbooks, we devised to mathematical writing types and teaching/learning models could being utilized in mathematics classes. And we investigated the influence of mathematical writing on the learning ability of students. We have experimented and investigated to after dividing experimental objects into two groups, experimental group and comparative group. We founded out, through these researches for mathematical writing teaming, that the experimental group of the former had obtained greatly better results than the latter in mathematical learning abilities and studying achievements. Based on these result, it is required to have an accumulation of research on teaching-teaming methods by using various types of mathematical writing study.
