In this research the education and training that had been received or wished to be acquired by the Science teachers in the experimental teaching of Biology in high schools, was investigated. It focused on the laboratory practice, didactic methods that can be used in more effective experimental teaching of Biology, pedagogic methods that can be implemented in laboratory team teaching, official and legal issues related to laboratory work and the organization of the seminars, which constituted the dependent variables of a quantitative analysis. A questionnaire consisting of closed type questions was answered by Science teachers of many specialties, who served in Secondary Education at Heraklion Crete prefecture. The asked teachers had not received adequate education in carrying out laboratory exercises of Biology neither during their university studies nor in in-service training. Most of them had taught the course theoretically but a few had carried out laboratory exercises of Biology. The need of training on issues of didactic practices and evaluation was firstly classified, with a significant percentage of methods that can be applied to provoke students' curiosity in scientific issues related to daily life and recognize the value of the Life Sciences by team collaboration and respect of others. 展开更多

Consciousness is the main quality one can ask architecture students. Consciousness means the ability to recognize that the design process is a "problem solving" activity and not an exercise of uncontrolled imagination. In architectural education, small structures are a common subject in American and European universities where the inductive teaching is practiced routinely. This teaching experiment is developed within a design studio course in the second year of an architecture degree course and regards design and construction of a small bridge l:l scale. The exercises focus on the role of structural behaviour within architectural design. The teaching method contributes to the perception of the great complexity of the design process, to the acquisition of an attitude of prudence in design choices and to attention to detail in the development of creativity. 展开更多

Nowadays, in order to satisfy the ISO 9001: 2015 requirements, organizations access to information from web sites, consultant guides, Internet forums, books, and courses, as a first approximation, however, the quality, reliability, validity, and accuracy of the information content in these is limited. The research topic of this study is the use of theoretical methodological tools, whose implementation supports the organizations in the fulfillment of requirement 4 of ISO 9001:2015, adapting it to their particular needs, minimizing rework in the documentation, increasing the motivation of the personnel involved and promoting well-being within the work environment. Some theoretical methodological tools were implemented in the case of Engineering laboratories of the Faculty of Higher Studies Arag6n, that support and complement the teaching-learning process in the theoretical-practical subjects of the curricula of the engineering bachelor's degrees, providing students with practical training in the use of equipment, devices, and tools, as well as extracurricular courses. In the study participated the stakeholders of laboratories. From the results, it was observed that the time for the documentation of the quality management system was reduced using the theoretical tools proposed in this study. In conclusion, this study will thus be useful as a starting point in using formal tools for the implementation of ISO 9001: 2015 standard. 展开更多

Over the years many famous scholars and experts from many aspects and multidimensional perspective discusses the role and importance of laboratory work and practice of education and teaching, practice shows that: the degree of awareness and attention to a university laboratory construction and practice teaching in a sense reflects the understanding of the university personnel training and higher education. In the past, "focus on the theory and lighten the practice," the idea has far-reaching impact, now we want to change old ideas; this is because in today' s quality education, construction, laboratory and practical education reform teaching content and methods are a part of education reform. We attach great importance to the English school laboratory building. In the new campus, the school has invested heavily to build five advanced equipment, it is a leading English Autonomous Learning Center. Independent Learning Centre is to stimulate students 'interest in learning, develop students' ability to multi-faceted, full use modern teaching equipment to improve English skills platform of independent centers of learning effect. 展开更多
