  • The kinetic structure of the content of instructions at the unit of 'heart and circulation' in "the common science", which was respectively given by two teachers majored in biology and two teachers majored in earth science was investigated. Concerning of the mean of the fundamental coefficient (B1), the mean of weighted coefficients (B2) and the progression of instruction (P), T4 (B1, 0.14; B2, 0.82; P; 0.86) teacher showed relatively lower kinetic structure and faster progression than those of the others. The other teachers showed a different level of the kinetic structure and progression: T1(B1, 0.21; B2, 0.86; P; 0.79), T2 (B1, 0.02; B2, 0.85; P; 0.80), and T3 (B1, 0.22; B2, 0.83; P; 0.78). T1 teacher who showed the largest total frequency of verbal elements, the great number of sorts of verbal elements and secondary span, had a higher level of the kinetic structure, but T4 teacher showed the lowest level of total frequency of verbal elements, the great number of sorts of verbal elements and secondary span. The main reason why T4 teacher's instruction achieved a lower level of kinetic structure was estimated that he neglected to reorganize teaching materials and he showed a small number of discourse units. In addition, the unit of 'heart and circulation' was less related to T4 teacher's major and T4 teacher had a shorter teaching experience than those of the others. T4 teacher also took charge of only one class, and this did not allow to instruct repeatedly.

  • This study investigated science education experts' perception of remote laboratory sessions (RLS) provoked by the COVID-19 pandemic. We conducted a total of 10 semi-structured interviews with experts in physics, chemistry, biology, and earth science education. As a result, science education experts primarily understood the RLS concerning pre-service teacher education and reconsidered the aim and goal of conventional laboratory education. On practices of RLS provoked by the COVID-19, they pointed out the learning loss due to deficiency of hands-on experience, decreased interactions between instructor and students, and instructors' increased burden. Meanwhile, they contemplated upon their adaptive implementation of RLS to suggest ways to improve RLS instruction and directions of post-COVID-19 science education. We recommend that RLS should be understood as a complemented version of minds-on teaching rather than a degraded version of hands-on teaching to elicit its full potentials. This study has its own significance providing an in-depth science educational perspective interpreting the RLS phenomena.

  • An 11-year-old, intact male Pekingese was brought to the Veterinary Teaching Hospital of Kangwon National University with a 10-day history of seizures. Fifteen days before coming to Kangwon National University, the dog had visited a local animal hospital for lameness, and non-steroidal anti-inflammatory drugs were prescribed to treat this symptom. However, 10 days before coming to our hospital, the dog experienced generalized seizures. Two days before his arrival, generalized ataxia and mental dullness also occurred. Our examinations revealed no remarkable findings on a routine blood test or X-ray. However, the neurological examinations confirmed mental dullness, generalized ataxia, and a lack of menace response and pupillary light reflexes. Nine hours later, dyspnea occurred, and 12 hours after that, the patient was euthanized per the client's request. A necropsy of transverse sections confirmed the presence of a prominent midline shift due to extended tumor growth. On histopathological analyses, pseudopalisading necrosis of the glial cells and microvascular proliferation were observed. In immunohistochemical analysis, glial fibrillary acidic protein, proliferating cell nuclear antigens, and ionized calcium binding adaptor molecule 1 immunoreactive cells were observed in the tumor area. Based on the results, the tumor was confirmed to be a glioblastoma. Primary intracranial tumors are rare in the veterinary field. This case report describes the clinical and histopathological findings of glioblastoma in a Pekingese.

  • The development of the education system and the labor market today requires new conditions for unification and functioning, the introduction of an innovative culture in the field of Education. The construction of modern management of innovative development of a higher education institution requires consideration of the existing theoretical, methodological and practical planes on which its formation is based. The purpose of the article is to substantiate the modern paradigm of organizing the mechanism of managing the innovative development of higher education institutions. Innovation in education is represented not only by the final product of applying novelty in educational and managerial processes in order to qualitatively improve the subject and objects of management and obtain economic, social, scientific, technical, environmental and other effects, but also by the procedure for their constant updating. The classification of innovations in education is presented. Despite the positive developments in the development of Education, numerous problems remain in this area, which is discussed in the article. The concept of innovative development of higher education institutions is described, which defines the prerequisites, goals, principles, tasks and mechanisms of university development for a long-term period and should be based on the following principles: scientific, flexible, efficient and comprehensive. The role of the motivational component of the mechanism of innovative development of higher education institutions is clarified, which allows at the strategic level to create an innovative culture and motivation of innovative activity of each individual, to make a choice of rational directions for solving problems, at the tactical level - to form motives for innovative activity in the most effective directions, at the operational level - to monitor the formation of a system of motives and incentives, to adjust the directions of motivation. The necessity of the functional component of the mechanism, which consists in determining a set of steps and management decisions aimed at achieving certain goals of innovative development of higher education institutions, is proved. The monitoring component of the mechanism is aimed at developing a special system for collecting, processing, storing and distributing information about the stages of development of higher education institutions, prediction based on the objective data on the dynamics and main trends of its development, and elaboration of recommendations.

  • The Research works published in the field of Korean science education in relation to the theories of 'J. Piaget', 'D. P. Bruner' or 'J. S. Ausubel' have been analyzed and their general pattern of study were determined. Specifically, based on science education related articles published in several Korean journals, the pattern of research about the three scholars' theory is identified with the classification of the specific kind of journal, year of publication, key word, field of study, field of research, and grade of school. The journals subjected to the present study include 'Journal of the Korean Physical Society', 'Journal of the Korean Chemical Society', 'Journal of the Korean Biology Society', 'Journal of the Korean Earth Science Society', 'Journal of the Korean Association for Research in Science Education', and 'Journal of the Korean Society of Elementary Science Education'. It is determined from the present study as follows: First, the total number of related articles published in said journals is 97, and 'Journal of the Korean Association for Research in Science Education' ranks first in numbers. In terms of time period, it is found that most of the researches has been carried out during the mid 90s, and is still popular today. In addition, our key word search revealed that the 'cognitive development' by Piaget is most widely studied in the articles and biology is the area that has been most frequently studied. As to the field of research, teaching study was the one that has been most widely studied. Further, many articles have focused their studies on middle school. In conclusion, it is found that the Korean research works so far made for the theory of 'J. Piaget', 'D. P. Bruner' or 'J. S. Ausubel' are rather limited to a certain area and field, etc.

  • This study aims to develop STS modules which consider the local concerns of Korean society and their authentic evaluation instruments. Their titles are as follows: 'Health-Aiding Foods, are they necessary?', 'Competition between Alien and Native Species', 'Living Lesson of Lake Shihwa', and 'Problems of food wastes; Would you like to throw them away, if they are money?' All of them deal with issues unique to Korean local situations. Each module consisted of two versions; a student worksheet and a teachers' guide. Students' activities were categorized into six processes such as group activities, investigation, discussion and presentation, experiments, field trip, and multiple intelligence activities. Various assessment tools and abilities for the decision-making in their STS classes were also included. In order to validate these modules, 24 teachers who have been teaching science, biology and environmental science in the secondary schools reviewed these modules and provided feedbacks about their validity and usefulness. We expect that the various rubrics included in each module will provide teachers creative and flexible assessment methods for students' understandings and their decision-making abilities toward the issues.

  • This study has been performed in order to achieve three objectives. They are as follows: To analyze, based on the research literatures, the nature of scientific inquiry ability and the characteristics of its constitutive elements. To identify inquiry skills and techniques essential to such areas as physics, chemistry, biology, and earth science. To develop instructional models and materials for enhancing inquiry ability on the part of high school students. It was found in the study that the scientific inquiry was interpreted in terms of different meanings according to the viewpoint of the person who are interested in the nature of science. The scientific inquiry has been viewed as the process of knowledge formation, scientific method, inquiry process or process skills depending on the epistemological, methodological, educational perspectives, respectively. It was also identified that certain kind of skills or techniques would be used for inquiry in only one specific area of the science. The skills and techniques are effectively learned when those are taught with specific knowledge in each area of the science. The model and materials for fostering scientific inquiry skills will be presented on the second part of the report.

  • The purpose of this study was to examine the content relevance of the 7th national primary science curriculum and textbooks. To fulfill the purpose of the study, we 1) analyzed the 7th national science curriculum of Korea, Californian science standards, the national science curriculum of England and Japan, and current Korean and Japanese science textbooks, 2) conducted a nationwide survey to gather opinions from students, teachers, and professors of teachers colleges about the relevance of the science curriculum and textbooks. Main findings of this study are as follows: First, the science contents at each grade level should be determined by the students' characteristics, not by an equal portion rule among physics, chemistry, biology and earth science. Second, the excessive overlapping and repetition of contents due to the spiral curriculum should be avoid. Third, the number of topics at each grade level should be reduced, and the similar topics and themes should be integrated for students' deeper understanding. Fourth, the number of science concepts and activities should be reduced to an appropriate level considering the time allotment for science classes, teachers workload, laboratory conditions, etc. Fifth, differentiated curriculum, such as in-depth and supplementary course, should be described not in science contents, but in teaching and learning strategy.
