According to studies, rehabilitation-promoting nursing care enhances the functional capacity of the elderly. The Elderly Services Act obliges municipalities to create a plan to support the elderly population, emphasizing home care and rehabilitation measures. A large portion of graduated practical nurses will be working with the elderly, so the education of practical nurses must meet the needs of the workforce. The study aimed to produce new information on the implementation of rehabilitation- promoting nursing care in the elderly service system and on the education of rehabilitation-promoting nursing care for the elderly in vocational institutions. The research data was collected in the autumn of 2020 through individual thematic interviews with practical nurse students (n = 8). The data was analyzed using inductive content analysis. Practical nurse students’ experiences of rehabilitation-promoting nursing care for the elderly were related to nurses’ time management, organizational practices, nursing competence, nurses’ attitudes, nurses’ practices, organizational development, implementation and development of practical education, factors affecting the use of aids, and technological aspects of aids in the future. In conclusion, it can be stated that the content of education and practical work life do not align. It is essential to increase competence in rehabilitation-promoting nursing care and to develop organizational practices.展开更多

文摘Blended teaching has emerged as a prominent subject in the recent reform and innovation of higher education.It has become imperative and guiding for colleges and universities to embrace a mixed teaching approach that aligns with the evolving needs of education and teaching in the new era.This paper aims to provide a comprehensive overview of the research status surrounding blended teaching,encompassing fundamental issues,teaching design,practical guidance,teaching effectiveness,and evaluation.By critically examining the current challenges associated with blended teaching,this study proposes optimization strategies including enhancing student participation and interaction,promoting deep learning,improving teachers’preparedness,teaching technologies,and curriculum design capabilities,strengthening top-level design,and perfecting evaluation and incentive mechanisms.These strategies provide new directions for the reform of blended teaching.
文摘Philology is a fundamental course for Chinese majors in higher education,which contains rich ideological and political education resources.In the context of the new era,integrating ideological and political elements into the course of philology is not only an inherent requirement of the course itself but also a necessary requirement for the development of education.This article explores the practical paths of integrating ideological and political elements into the course of philology by mining its ideological and political resources,providing theoretical reference and practical inspiration for comprehensively promoting the ideological and political reform of language and literature courses in the new era.
文摘Purpose:To explore the practical effects of using the flipped classroom approach based on outcome-oriented educational concepts in nursing practical training at vocational colleges.Methods:From February 2023 to February 2024,a total of 62 nursing trainees from our school were sampled and randomly divided into a study group and a control group using a randomized controlled trial design,with 31 students in each group.The control group received conventional training,while the study group received practical training based on the outcome-oriented educational concept in flipped classrooms.Comparison was made between the two groups on assessment scores,teaching satisfaction,and self-directed learning ability ratings.Results:Statistical comparisons showed that the study group’s assessment scores,teaching satisfaction,and self-directed learning ability ratings were significantly higher than those of the control group(P<0.05).Conclusion:The flipped classroom model based on outcome-oriented educational concepts in nursing practical training at vocational colleges can improve students’assessment scores and self-directed learning abilities,and enhance teaching satisfaction,demonstrating potential for wider application and dissemination.
文摘The emergence of new engineering disciplines has resulted in the growing trend of cross-discipline,and the enhancement of students’technical application ability has become the main teaching objective of engineering disciplines.For this reason,the Internet of Things(IoT)engineering program should be actively reformed,providing students with sufficient opportunities to improve their practical skills.This paper identifies the challenges within practical teaching of IoT engineering,delves into effective strategies for practical IoT teaching within the context of emerging engineering disciplines,and presents practical teaching experiences from the School of Information Engineering at Hainan University of Science and Technology as a case study.The aim is to offer guidance and insights to educators in this field.
