The aim of this study is to analyze critically the meaning of 'good instruction'. In this article, the researchers emphasized the activities of teaching and learning as two essential elements of good instruction. The antecedent studies on good instruction have limitations in that they regarded good instruction as an instrument rather than valuable activity itself. This study consisted of three parts. Firstly, the researchers tried to clarify the meaning of good instruction underlying antecedent studies on instruction. Secondly, the researchers tried to analyze characteristics of good insturction suggested by antecedent studies. Thirdly, the researchers attempted to define a new meaning of good instruction. A new meaning of good instruction should be defined in accordance with characteristics of three commonplaces composing instruction such as teaching activity, learning activity and good interactions between teacher and learner. Good instruction can be defined as followings. Good instruction means an instructional activity which can change the student's meanings of experience as a result of interactions among teacher, learner, and educational materials.

We have been received questionnairs on the general characteristics and cognition of radiotechnological students, instruction which they hope, and the present processing actural states of instruction to 610 numbers of 2, 3 years radiotechnological students in korea. We have been perceived the actural states of radiotechnological instruction by the results of questionnaires, therefore, the imperfections of student's contentment, lack of instruction plan and audio-visual material's practical use, insufficient of study activities on instruction process, lack of clinical adaptation and practice of lecture evaluation were founded. We propose the solving method of these problems as the improvement of instruction. It is necessary for the will and effort of college and teacher to practices these problems.

In this study, 27 pre-service teachers presented virtual mathematics instruction to develop his/her own teaching practice ability. I found several attributes in their virtual mathematics instruction such as connecting contents, asking justification, encouraging students' communication, representing variously, and using ICT etc. These will be the characteristics of the future mathematics class. When peer pre-service teachers assess presenter's instruction quantitatively, there are differences in the results between expert and pre-service teachers. Pre-service teachers didn't find the elements of student self assessment or group assessment and communication activities at the virtual instruction. When they assess peers' virtual instruction qualitatively, the results are specific or new ones compared with the quantitative assessment elements. Thus I suggested some implications for the mathematics pre-service teachers' virtual instruction in the view of teacher education.

Modern society requires people with practical knowledge that is able to recognize actual problems in the complex reality and solve the problems. Due to that reason, the 7th National Curriculum aims to basically cultivate ability adaptable to information-oriented global age by maximizing students' individuality and creativity. However, as existing education is hard to improve creativity, logical thinking, information processing skills, and problem-solving ability in the information-oriented age, self-directed learning is getting highlighted. Therefore, this study aimed to look into how learner-oriented IPER for self-directed learning and problem-based learning(PBL) in middle school science affected academic achievement of science and self-directed learning characteristics. As the results of the study are as follows. First, as the result of pre-and post-test to compare and analyze the effects of IPER instruction model and PBL instruction model on learners' academic achievement increase, it showed that the class with IPER instruction model was more effective. Second, as the result of pre-and post-test to compare and analyze the effects of IPER instruction model and PBL instruction model on self-directed learning characters, IPER was more effective than PBL overall, and among sub-areas, 'openness', 'self-concept', 'initiative', 'future-oriented self-understanding', and 'self-evaluation' were more effective in IPER while 'creativity' was more effective in PBL. However, among sub-areas 'responsibility' and 'learning enthusiasm' didn't show statistically significant difference. Third, the results of the post-survey to compare and analyze learners' perception regarding the application of IPER instruction model and PBL instruction model, the two models were positively affective. In addition, as the result of comparing the two models, IPER was more positive than PBL.

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.

In this study, elementary school students' science learning characteristics together with the levels of inquiry requirement in elementary school science experiment instruction were investigated in terms of the affective domain. We divided seventy-three students of the fifth ade into two groups according to the levels of inquiry requirement. After each instruction had been implemented, the characteristics of the students' learning in terms of the affective domain were compared and analyzed within the context of the levels of inquiry requirement. There were no significant differences between Level 1(LL) and Level 2(HL) groups in terms of the affective characteristics. These results may be caused by the burden imposed by the difficulty in thinking through and setting up the experimental methods. However, the HL group students' levels of interest in science experiments was higher than that of the LL group. In conclusion, the HL instruction contributed little to the improvement of affective characteristics. Some possible reasons might be that students felt difficulties with the somewhat unfamiliar instructions which required them to design and perform experiments. Higher levels of interest in science experiments amongst HL students' implies that well-organized and continuous exercises involving the design and performance of experiments could improve students' scientific affective characteristics.
