In most classrooms, teachers talk more than students. Teachers have been thought to be knowledge-donors and students have been thought to be knowledge-acceptors, so teacher-talks were thought to be more important than student-talks. But student-talks are very important to the students: not only to the students who speak out their opinions or answer to the questions given to them, but also to the others who say nothing in the class. Many students in Korea are not so fond of speaking out something to all the class, so some teachers are using a strategy: to say something as if he for she) is a student in the classroom. What teachers talk are not the words of the teacher-talks. They are only talked by the teachers, but they function like student-talks. To study this type of talks are needed to help both teachers and students but there are not much research about this. So in this paper we a) name it Pseudo Student Talk (PST), b) define it as 'a kind of talks that are not talked by students of the class but its functions are very similar to the student-talks', c) classify PST in 'EBS 2005 science class for 7th grade' according to types of student talks (categorized by Lemke, 1990), and d) show the usage of each kind of PST.

It is critical for adolescents to foster self-efficacy, creativity, and adventurous spirit as well as plans for appropriate career path in order to become good members of society. During this adolescent period, newspapers will be a good learning material as they deliver various and timely information in refined language. In this paper, we analyzed the impact of NIE on development of self-efficacy, awareness of career path, and entrepreneurship through comparing adolescents who regularly read newspapers with those who do not. We came up with the following result after analysis of surveys (with a sample size of 283) that targeted middle school and higher grade elementary school students across Korea. We confirmed that reading newspapers has a positive impact on development of self-efficacy, awareness of career path, and entrepreneurship. More specifically, reading newspapers regularly has a positive impact on development of self-efficacy that subsequently has a positive impact on development of awareness of career path and entrepreneurship. Therefore, we found that simply reading newspapers regularly has a positive impact on development of self-efficacy, awareness of career path, and entrepreneurship with no special programs utilizing the newspapers. This is because various information and opinions in newspapers help adolescents to develop their own views, improve understanding and awareness of career, and development of sociality including creativity and adventurous spirit. There is the meaning as the first research that this research checks what the NIE of the adolescents affects the positive impact to not only the self-efficacy and career awareness but also entrepreneurship.

This study was performed to analyze the relationship between the participative motivation and satisfaction of adolescents participating in Green Camp which was the field centered forest experience camp as analyzing the factor of the participative motivation and its influence on the satisfaction. Also, this study identified the changes in creative personality before and after participation to Green Camp. In results, there were five motivation factors: 'Adventure and Interest', 'Forest Activity', 'Improve Physical Health', 'Rest', 'Suggestion'. When respective factors were analyzed, the mean of 'Interest and adventure' was the highest at 4.303, and then 'Forest activity' at 4.287, 'Rest' at 3.970 followed. In the case of participant satisfaction, 'the teaching materials and tools of the camp' was the highest at 4.530, and then 'contents of the camp' at 4.410, 'lecture performer of the camp' at 4.229, 'the way of progress of the camp' at 4.036, 'the place of the camp' at 3.952, 'the passage time of the camp' at 3.843 followed. It showed that 'Forest activity' factor and satisfaction had a positive relationship (p<0.05). In addition, the means of creative personality before-and after-program participation increased from 3.687 to 3.773 (t=-2.218, p=0.029). Based on the analysis of satisfaction, this study suggested improvements of Green camp. Also, it proved that the participation Green camp had influence on the creative personality. The finding of this study is meaningful in that it proposed the necessity of activation forest education focusing on experience.

This was to investigate how the slow learners who specially belonged to low-SES, or North Korean defectors showed their errors in mathematical learning. To conduct the study, two groups for each minority group participated in the study volunteerly during the Winter vacation, in 2011. Based on the preliminary interviews, a total of 15 units were given, focusing on building mathematical basic concepts. As results, they had some errors in common. They both were in lack of understanding of the terminologies and not able to apply the meanings of definitions and theorems to a problem. Because of uncertainty of basic knowledge of mathematics, they easily lost their focus and were apt to make a mistake. Also, they showed clear differences. North Korean defectors were not accustomed to using or understanding the meanings of Chines or English in Korean words in expressing, writing mathematical terminologies and reading data on the context. Technical errors, and misinterpreted errors were found. However, students from the low SES showed that they were familiar with mathematical words and terminologies, but their errors mostly belonged to carelessness because of the lack of mastering mathematical concepts.

Teachers' perceptions about curricular objectives are very important to achieve given educational objectives. This study examined teachers' perceptions about priority and hinderance of science objectives. The national science curriculum stated four areas of objectives: inquiry, knowledge, attitude, and STS. A total of 76 elementary and 217 secondary teachers were responded to questionnaire developed for this study. Non-parametric statistics, such as Friedman test, Kruskal-Wallis test, and chi-square test were used by using SPSS/PC program. Teachers in general ranked the inquiry first among the four areas at their perception on the national curriculum, on themselves, and on their instructions. Elementary teachers ranked inquiry higher than secondary science teachers, while secondary science teachers ranked knowledge higher than elementary teachers. As factors hindering teachers from achiving the objectives, elementary teachers pointed out overcrowded classroom and secondary science teachers pointed out college and university entrance examination respectively.

The purpose of the this study is to analyze consulting demands in vocational education and training (VET) high schools participating the apprenticeship system in Korea. The results of the study are as follows. Firstly, there are 9 sections of consulting that teachers in charge of apprenticeship program in VET high schools demanded. Especially, the demands for the consulting that related with 'student evaluation', 'apprenticeship program development and organization planning of schools' curriculum', 'selection and management of enterprises', 'organization of apprentices classes and student management', 'teaching & learning activities and textbook development' were relatively high. Secondly, there were differences in demands of consulting by VET high schools' current management status. By the type of organization, demands for consulting of both 'training center in main school' of organization and 'training center in common' of organization were higher than 'independent school' of organization generally. By the type of apprenticeship program hours, demands for consulting of both 'above 1400 hours' and '1200 ~ 1400 hours' were higher than 'less than 1200 hours' generally. By the type of OJT operation, demands for consulting of 'a type of OJT that is operated in long term(more than 2 weeks)' were higher than 'a type of OJT that is operated weekly' generally. As a result from above, there are some pre-requisites for the stable operations of VET high schools. 1) The apprenticeship program shall be developed not to interrupt school's regular curriculum. 2) For the smooth management between apprenticeship program and school curriculum, the academic calender has to be established so as the type of OJT operation. 3) The cooperation among the participating schools in part of the organization is unavoidable.

Purpose: The aim of this preliminary study was to evaluate the effect of Problem-Based Learning (PBL) curriculum on development of comprehension of basic medical knowledge and quality of semi-structured problem solving including scientific reasoning skill. This scientific reasoning contained five components including: size of simple, design of research cause-effect, construction of risk factor, analysis statistic of data, interpretation of result. Materials and Methods: Seoul National University Dental students (100) participated in this experience during two weeks, 2004. Forty eight multiple-choice questions (MCQ) concerned "Infection Control and Prevention" were asked before and after two sections of Lecture-Based Learning (LBL) and PBL (pretest-posttest control group design). A semi-structured problem in epidemiological research was asked to these students after two sections (posttest-only control group design). Data (mean and SD) were analysed using the t Test for two independent samples (p<.05), comparing PBL versus LBL. Results: Our analyse of scores show no difference between LBL and PBL in the development of comprehension of "Infection Control and Prevention". The quality problem solving (epidemiological research) was significantly different between the two groups (p=.029); specially, two components' scores of reflection on scientific reasoning cause-effect (p=.000) and interpretation of result (p=.001) were significantly better for PBL than for LBL. Conclusion: Theses results indicate that comparing LBL and PBL, PBL curriculum have not been disadvantaged in comprehension of basic knowledge, and have contributed to develop the scientific reasoning in problem solving.

In school mathematics, the definition and concept of a differentiation has been dealt with as a formula. Because of this reason, the learners' fundamental knowledge of the concept is insufficient, and furthermore the learners are familiar with solving routine, typical problems than doing non-routine, unfamiliar problems. Preceding studies have been more focused on dealing with the issues of learner's fallacy, textbook construction, teaching methodology rather than conducting the more concrete and efficient research through experiment-based lessons. Considering that most studies have been conducted in such a way so far, this study was to create a lesson plan including teaching resources to guide the understanding of differential coefficients and derivatives. Particularly, on the basis of the theory of Historical Genetic Process Principle, this study was to accomplish the its goal while utilizing a technological device such as GeoGebra. The experiment-based lessons were done and analyzed with 68 first graders in S high school located in G city, using Posttest Only Control Group Design. The methods of the examination consisted of 'learning comprehension' and 'learning satisfaction' using 'SPSS 21.0 Ver' to analyze students' post examination. Ultimately, this study was to suggest teaching methods to increase the understanding of the definition of differentials.

In this study, a survey was conducted to determine the understanding by teachers at KIPO-funded high schools of the specialized training of invention patent personnel. The subjects were 4 high schools and 126 copies of questionnaires were collected for analysis. The results of this study are as follows. First, teachers understand that it is particularly important to provide a specialized training for students so that they can more effectively adapt to the changes in their lives. They also consider basic job skills training, moral education and job readiness training as equally important. Second, they recognize the necessity for a specialized training of invention patent personnel. Third, they think that redundant teachers arising from the reform of the curriculum for specialized training should be provided with minor training. Fourth, they think that the reform of the curriculum for specialized training should consider the following aspects: the development of a curriculum for invention patent-specialized high schools, the strengthening of administrative financial supports, the creation of a consensus among those involved for the success of the specialized training, the development of textbooks and materials, and the consideration of the future prospects and current conditions of the invention patent industry. Fifth, they think that the successful operation of specialized high schools requires the consideration of the following factors: users' understanding, conformance, selection & concentration and uniqueness.
