This study examines how practical work in science was introduced in British schools and became an important part of school science activities during the second half of the 19th century. Firstly, the establishment of a national education system in Britain is reviewed. Secondly, a general development of school science teaching is summarized with a special attention to students' enrollment in science subjects. Thirdly, the practical work in elementary schools are discussed in relation to the introduction of Object Lessons in curriculum. Then, the situations of practical work in science in secondary schools, particularly in Organized Science Schools and some famous public schools, are illustrated. Finally, the overall development until present days is critically discussed in relation to the types and aims of practical work in science.

The purpose of this study is to explore how the practical knowledge used by an elementary school science teacher during learner-centered science instruction can promote elementary students' construction of positive emotion. Using an auto-ethnographic approach over a period of three months, the researchers collected students' interest diaries, post interviews with students, video recordings in science classes, and students' personal diaries and analyzed them by means of the constant comparative method. In this way, the researchers categorized the structure of the practical knowledge held by the teacher and explained how it was applied in learner-centered science instruction to promote students' construction of positive emotion. Three images of an elementary science teacher's practical knowledge emerged and can be categorized under the following headings: 1) 'From science classroom to science $caf{\acute{e}}$', 2) 'Pleasant experiment class for all students and the teacher', and 3) 'A science class for students who were marginalized'. These images were backed up by principles and rules, and the teacher came to embody these images as he implemented these rules. This study also discusses how the impact of a science teacher's practical knowledge on students' construction of positive emotions can be interpreted as promoting positive outcomes rather than negative sanctions, meeting students' expectation from lab activities, and meeting the specific needs of marginalized students in a science class.

In their teaching practice, teachers encounter multi-dimensions of pedagogical challenges. The recognition and reflection on these challenges is crucial to advance our science teaching. This study looked into science teachers' dilemmas of their teaching practical work through their written cases. Dilemma cases are teachers' narratives organized around important events of teaching and learning. It can reveal teachers' situated cognition and be used as lens to investigate complex realities of science teaching and learning. 26 pre- and in-service elementary teachers' dilemma cases of science practical work were carefully collected and analysed to interpret what constitute tensions in elementary science practical works. They were largely grouped into three: Curriculum and Institutional Relevance, Students Relevance, Nature of School Experiments Relevance and divided into 7 subheadings: 'Authority of Curriculum(textbook)', 'Disappointment at external support', 'Students' interests and safety', 'Students' unscientific and inert attitude', 'Difficulty of showing expected results', 'Generalization through experiment', 'Knowledge acquisition and authentic inquiry'. Each dilemma was interpreted in terms of the tensions which constitute contradictory beliefs, values, expectation and realities. These dilemmas enabled to expose actual conditions of elementary science practical work and teachers' challenges otherwise can not be seen easily. Science teacher educators also can get some implications to overcome the gap between theory and practice in their teacher education.

The objectives of this study are to consider about the research of a costume and a discussion about a system of costume by practical science scholar in the late period of Chosun Dynasty. The result are descrived as follows: 1. The purpose that practical sciellce scholars researched a costulne was not only the intellectual research but also to make a basis in order to reform a uncorrected costume's system. Their study had two point. The one was the investigating research about the origin and change of the costume. The other was the study about a formation of costume. 2. The practical science scholars determined the directions to reform a wrong costumes' system on the basis of the research about a costume. They had three directions. Those were a conservatism, a rationalism to think the realities of life and a reformation. 3. The practical science scholars' thinking was to pursue the origin form and the practical use. This two axis show the direction to improve our costulne's culture now a day.

Background: As the medical knowledge base grows at an accelerating rate, evidence-based clinical performance becomes increasingly important for providing quality care. Previous studies have highlighted the need to promote job crafting to actualize evidence-based practical skills in the medical field. This study aimed to investigate the degree of evidence-based practice among dental hygienists and assess the impact of job crafting on the evidence-based practical skills of dental hygienists. Methods: Dental hygienists working at dental hospitals and clinics in Seoul and Gyeonggi Province were surveyed between February 28 and April 6, 2023. The sample was comprised of 267 participants. The hypotheses were tested independent t-tests, one-way analysis of variance, Pearson's correlation coefficients, and multiple regression analyses using SPSS 29.0. Results: The degree of job crafting by dental hygienists demonstrated significant differences based on educational attainment, workplace size, and workplace type. Evidence-based practical skills exhibited significant variations based on educational attainment and job position. All job crafting subfactors demonstrated positive correlations with evidence-based practical skills. The job crafting subfactors affecting the evidence-based practical skills of dental hygienists were 'increasing structural job resources' and 'increasing challenging job demands,' which together explained 38.7% of the variance in evidence-based practical skills. Conclusion: This study demonstrates that job crafting was positively and significantly correlated with evidence-based practical skills. To strengthen the job crafting ability of dental hygienists, improving environmental conditions and fostering an organizational culture that motivates continued participation in education is necessary. The development and promotion of programs that enable learning of the latest evidence should be actively pursued. Additionally, regular attendance at workshops and participation in organizational evidence-based practice education programs are necessary.

Practical science means open and objective attitude as a new scholarly tone which gets out of Confucianism tradition and its closeness. It is concerned about practical aspect and its thought prevailed from the mid-16th century to the mid-19th century in feudal system. It is, also, the attitude seeking truth based on the facts, which is removed from the falsehood in politics, economics and social life. It is regarded as a social revolution which governs tile country economically and is utilized to stabilize and enrich a human living life. The new academic tradition appeared in the process of development of modernization proclaimed it to be utilized in modern-oriented independency. Modern historians have greatly studied the knowledge of early philosophy, while Korean oriental medicine has developed, basing on the cultivation of the mind, virtue, and benevolence through Han Bak-Keun(who showed much interest in realistic, economic and social system) and Jung Yak-Youg(who compiled all available data into one book). From Ko-Ryo dynasty to the mid-Yi dynasty Korean oriental medicine scholars struggled to develop oriental medicine in an attitude searching truth based on the facts. Among them Huh Jun's achievements and the content of his writings suggest any things with a view of practical science. These are neglected by most scholars so far, but I have surveyed as follows : 1) the revolution in oriental medical science system 2) the standardization of pharmacy appliance 3) the popularization of medicine supplies 4) cooperation of industry and academy in medical science field From the above I concluded as follows : practical science in Korean medical science began from Ko-Ryo dynasty and compiled in Ku Am Huh Jun in the period of King Sun-Jo of Li dynasty. With this repect, the pioneer in practical science in Korea is Ku Am Huh Jun. To search tile pioneer in practical science rightly we should study the history of Korean medical science.

The purpose of this study was to research elementary school on safety education in the subject of practical arts. The subject of practical arts of an elementary school have positive attitude about safety education and must prevent an accident to be able to happen during a class of a practical course previously. Safety education has further an interest on subject of practical arts of practice and must induce an aggressive interest of teachers in order to be able to prevent an accident previously. As the above results, to raise the perceptions of elementary school teachers on safety education in the subject of practical arts, it is necessary to search for ways to induce teachers' active interest in safety education and help them experience safety education in the subject of practical arts at teacher training centers.

The purpose of this study is to clarify the specific terms of epistemic and epistemological by reviewing the literature on epistemological understanding of science learning, examine the necessity of epistemic discourse analysis based on the view of social epistemology, and provide an exemplar of practical epistemology analysis for elementary children's science learning. The review was conducted in terms of meaning and terminology about epistemic or epistemological approach to science learning, epistemology of/for science, and methodologies for epistemic discourse analysis. As an alternative way of epistemic discourse analysis in science classroom I employed practical epistemology analysis (by Wickman), evidence-explanation continuum (by Duschl), and DREEC diagram (by Maeng et al.). The methods were administered to an elementary science class for the third grade where children observed sedimentary rocks. Through the outcomes of analysis I sought to understand the processes how children collected data by observation, identified evidence, and constructed explanations about rocks. During the process of practical epistemology analysis the cases of four categories, such as encounter, stand-fast, gap, and relation, were identified. The sequence of encounter, stand fast, gap, and relation showed how children observed sedimentary rocks and how they came to learn the difference among the rocks. The epistemic features of children's observation discourse, although different from scientists' discourses during their own practices, showed data-only conversation, evidence-driven conversation, or explanation inducing conversation. Thus I argue even elementary children are able to construct their own knowledge and their epistemic practices are productive.

The purpose of this study is to suggest an improvement plan for the National Technical Qualification Practical Evaluation focusing on National Competency Standards. First, in order to strengthen practical techniques such as field abilities and expertise, practical evaluation methods were applied to the National Competency Standards, referring to a learning module focused on field performance. Second, an expert advisory committee in the field of organic agriculture was utilized to compare, analyze, and match the competency unit and competency unit elements of the National Competency Standards with the national technical qualification examination standards in field of organic agriculture. In addition, in order to identify work in progress in the industrial field, share professional practice skills, and analyze facilities and equipment, we visited an organic agriculture industry site. Through this, a practical evaluation exam was developed. Subsequently, in order to confirm the adequacy of the developed exam, the pilot test assessment was conducted for those majoring in organic agriculture. Finally, as a feasibility study, a survey was conducted. Based on the results, greater technical job competency in the field of organic agriculture will contribute to strengthening knowledge in this field by suggesting an improvement plan for the national technical qualifications practical evaluation method in the field of organic agriculture.
