  • Clear analysis and diagnosis of various characteristic factors of individual students is the most important in order to realize individual customized teaching and learning, which is considered the most essential function of math artificial intelligence-based digital textbooks. In this study, analysis factors and tools for individual customized learning diagnosis and construction models for data collection and analysis were derived from mathematical AI digital textbooks. To this end, according to the Ministry of Education's recent plan to apply AI digital textbooks, the demand for AI digital textbooks in mathematics, personalized learning and prior research on data for it, and factors for learner analysis in mathematics digital platforms were reviewed. As a result of the study, the researcher summarized the factors for learning analysis as factors for learning readiness, process and performance, achievement, weakness, and propensity analysis as factors for learning duration, problem solving time, concentration, math learning habits, and emotional analysis as factors for confidence, interest, anxiety, learning motivation, value perception, and attitude analysis as factors for learning analysis. In addition, the researcher proposed noon data on the problem, learning progress rate, screen recording data on student activities, event data, eye tracking device, and self-response questionnaires as data collection tools for these factors. Finally, a data collection model was proposed that time-series these factors before, during, and after learning.

  • The purpose of this study was to investigate the perception of the scientifically gifted high school students to the research and education (R&E) program. 270 scientifically gifted high school students participating in R&E program were sampled and surveyed according to the R&E' purpose, the process of topic selection, the advantage, and disadvantage of R&E. 4 students among them were interviewed in depth. Students perceived the purposes and advantages of R&E as fostering the scientist' qualifications, providing the research opportunities, and improving the inquiry ability and the disadvantages of R&E as the time consumption in research, the participation as a sideline, and the difficulty of contents. The R&E program was mainly composed of a pre-determined topic, fixed procedures, and expert's settlements in the problem-emerging situation and was not cognitive but technical apprenticeship. In addition, students considered the participation of R&E as a chance of experience about the high techniques and the valuable instruments instead of the improvement on the creative problem-solving ability. The role of mentors in the R&E program is so important that it affects largely on the productive participation and the perceptions of science and scientists.

  • Transportation project appraisal should be precise in order to increase the social welfare and efficiency, and it has been evaluated by only a single criterion analysis such as benefit/cost analysis. However, this method cannot assess some qualitative items, and cannot get a proper solution for the clash of interests among various groups. Therefore, the multi-criteria analysis, which can control these problems, is needed, and then Saaty has developed one of these methods, AHP(Analytic Hierarchy Process) method. In AHP, the project is evaluated through weighted score of the criteria and the alternatives, which is surveyed by a questionnaire of specialists. It is based on some strict suppositions such as reciprocal comparison, homogeneity, expectation, independence relationship between multi-criteria, but supposing that each criterion has independence relation with others is too difficult in two reasons. First, in real situation, there cannot be perfect independence relationship between standards. Second, individuals, even though they are specialists of that area, do not feel the degree of independence relation as same as others. This paper develops a modified AHP method for solving this dependence relationship between multi-criteria. First of all. in this method, the degree of dependence relationship between multi-criteria that the specialist feels is surveyed and included to the weighted score of multi-criteria This study supposes three methods to implement this idea. The first model products the degree of dependence relationship in the first step for calculating the weighted score, and the others adjust the result of weighted score from the basic AHP method to the dependence relationship. One of the second methods distributes the cross weighted score to each standard by constant ratio, and the other splits them using Fuzzy measure such as Bel and Pl. Finally, in order to validate these methods, this paper applies them to evaluate the alternatives which can control public resentments against Korean rail path in a city area.

  • This study has been motivated by the awareness that studies on science and technology policy do not have an independent academic identity in Korea as of 2017. This research has been analyzed 19 books that have covered science and technology policy published in Korea and explored whether those have a definition of discipline and core research scope which are the key elements forming academic paradigm. As a result, this study concludes provisionally that studies on science and technology policy in Korea are still at a stage that has not yet formed a paradigm. Therefore, this work newly proposes the definition of discipline and research scope necessary to complete the paradigm of studies on science and technology policy based on this conclusion. This paper has firstly defined that studies on science and technology policy are the policy-oriented discipline. It is (1) promoting the development of science and technology itself by studying and analyzing the various phenomena of politics, economy, society, and culture related to science and technology activities as well as science and technology and (2) makes the national and public sector improve problem-solving competence using science and technology. This work also proposes a research scope consisting of four research areas such as (1) policy process of science and technology, (2) public management of science and technology, (3) R&D management and (4) technology innovation. 'Policy process of science and technology' and 'public management of science and technology' among four research areas are the new research ones reflecting the definition of studies on science and technology policy proposed in this paper. Additionally 'R&D management' and 'technology innovation' are the traditional research areas which have also included existing researches regarding science and technology policy.

  • This study has been undertaken in the light of constructivist view of teacher education. Participant observation, unstructured interview and questionnaire were used to explore the process and the role of practicum in science teacher education. The subjects were 19 student teachers majoring in physics education; 8 had participated at boys junior high school, 11 at senior high school. The student teachers had very critical and negative perception on their school days' science lessons. They had expected to do 'better' in their practicum but there were only 3 to 5 opportunities of teaching under the umbrella of textbook. Explanation in the classroom and solving exercise problem were the main features of student teachers' lessons. Much of the lessons were similar when it is to same topic and the main reference for their lesson preparation was the textbook. The student teachers felt the design of teaching approach as the most difficult thing during their lesson preparation. They realized that teaching is harder than they thought and they should consider students' level and responses. Though they had become to have more positive perception on teaching job through their field experiences, their decision on job preference did not change. More than half did not want to be a teacher. The student teachers recognised the courses related with science education as the most useful to their teaching in practice among the program of college of education which they had taken. The experience of writing one lesson plan or teaching in front of their peers, designing a new demonstration equipment were recognised as valuable and helpful element of the courses. They proposed to reduce the amount of general education courses and to emphasize the courses relevant with science education and practicum. The limited opportunity of teaching in practicum was pointed out as problematic. Though the practicum was recognized as a 'good' experience to student teachers, it was confined by textbook and limited teaching opportunity. In conclusion, the practicum was not organized and implemented as a meaningful experience of science teaching and learning. There should be more structured studies on what kind of perceptions and experiences the student teachers had brought to the science teacher education program, how they interact with the elements of the program and how they affect to their science teaching. The structure and content of practicum also should be studied and developed so as to make practicum as a meaningful experience of science teaching and learning.

  • In this study, we analyzed activities in life science chapters of middle school 'science' textbooks for the 2009 revised Korea national curriculum and examined the difference between the analysis based on scientific practices and the analysis based on inquiry skills. As a results, there was a lot of inquiry skills in the order of 'reasoning', 'observing', 'classification' in the all of grade. In scientific practices, 'data analysis and interpretation' and 'constructing explanations and devising problem solving' were biased. This shows that life science inquiry activities in middle school 'science' textbooks are lacking in diversity in scientific practice elements as well as inquiry skills, and that the goals of the activities are limited. In addition, through the interrelationships between scientific inquiry skills and scientific practice elements, we examined contents relevance in the transition from inquiry function center to scientific practice, and compared with the results of inquiry activities in textbook, The results of this study were matched monotonously due to the tendency to basic inquiry-data interpretation / basic inquiry-explanation. This comes from results of the lack of diversity in activities presented in middle school 'science' textbooks. In this study, it is suggested that efforts should be made to include diverse scientific practice elements in the process of realizing 2015 revised Korea national curriculum from the simple and diversity-less inquiry activity through analyzing the textbooks of the 2009 revised Korea national curriculum.

  • Creativity is an essential ability for a successful design task, mainly because design is an activity creating something new. As the sphere of design has expanded and become complex, the design task goes beyond an individual designer's capability. Therefore, it is necessary to organize a design team consisting of various team members with diverse expertises. The aim of this study is to find out the impact of fundamental attributes of members on the group creativity in order to establish a guideline for building a creative design team. Heterogeneous teams and homeogenous teams were created according to three main factors of group creativity namely, personality, field and experience. The group creativity of each team were evaluated through protocol analysis of design activities as well as the comparison of problem solving processes and outputs. It was identified that the impact of design teams on the group creativity was distinctively different in four phases of the design process (preparation, divergence, convergence, and execution) regarding creativity properties such as fluency, elaboration, originality, usefulness. Based on these findings, a schematic model for building a design team in order to enhance the group creativity by composing the most appropriate team members for each phases of the design process was developed.

  • Both curriculum and textbooks play an important role in the process of didactical transposition from mathematics as a science to school mathematics. The 2009 revised national curriculum for mathematics introduced the system of grade-band, so its achievement criteria for mathematical contents tend to be addressed more and less generally in the curriculum. We need to investigate whether the achievement criteria were applied meaningfully in elementary textbooks for mathematics. This study aims to recognize the connection between the curriculum and the textbooks and make a suggestion for composing the following curriculum and its textbooks. To do this, we analyzed the mathematics textbooks for 1~2 grades in relation to the mathematical contents as per reconstructed one of curriculum achievement criteria, the mathematical terms and symbols, and the mathematical processes -mathematical problem solving, mathematical reasoning, mathematical communication. Based this analysis, futhermore, this study includes some didactical discussions and implications for development of mathematics textbooks in 3~4 and 5~6 grade-bands.

  • In recent times, increasing is the number of civic participation government policy decision models through the application of the service design process. It's because the effect of a policy is cut in half due to the low acceptance will for police execution, which could occur in the supplier-oriented policy-decision process in the past. For solving out such a problem, civic participation policy service design has been under way in the name of 'National Design Group' led by the Ministry of Government Administration and Home Affairs starting 2014. A sharing village is a village community in a broad sense for the purpose of giving effect to sharing economy, aiming to maintain sustainability through sharing consciousness raising between village members, coexistence and cooperation. This study presented a solution to the 3 sorts of city problems, i.e. sharing village, urban generation and youth employment settlement in combination by grasping the problems of the existing sharing village, and using service design method Toolkit However, there needs to be a follow-up research through continuous verification, and improvement of problems for the time to come because the casual relationship between research subjects is extensive, and this study has limitations in the satisfaction survey for verifying the result satisfaction, which individual subjects have, consequent on the suggestion of the way of solution, and the research period as well.

  • This study based on dual aspects of service quality aims at classifying service quality attributes by Kano model and also providing the necessity to decide which service quality would be carried out preferentially in the service industries(hotel service, repair service, education service, medical service). The first purpose of this study, therefore, is assorting the service quality by the Kano model about four service industries based on Schmenner's service process matrix. Secondly, this has an intention of drawing preferred considerations and putting forward measures to increase the customer satisfaction by Timko and PCSI Index. The result of this study is as follows. First of all, it was found that tangible attributes classified the attractive quality and Timko's score also was very high in four service industry. That is to say that tangible attributes in service industries could be interpreted into having very high importance at standards on service quality estimation of customer. Second, all but repair service of the service industries suggested empathy dimension to have flexibility solving and understanding the customer's problem could be improve the customer satisfaction. Finally, the common result between them was empathy dimension classified attractive quality in all industries. That is because present satisfaction was not reached customer expectation so there would be a improvement of empathy dimension preferentially.
