翻转课堂是当代教育理念下发展形成的一种新型教学方式,将其合理应用于我国初中体育教学较传统教学方式能够更好地满足当代学生的体育学习要求。但由于该教学理念在我国刚刚进入初期应用阶段,很多细节方面仍有待完善,因此,教师还应进行细致研究,加强新型教育工作实践,制定科学、合理的翻转课堂教学策略,提高初中体育教学工作效率。  相似文献

使用自行设计的实验装置,对超高含水原油的流动特性和初始沉积过程进行探究。系统研究实验温度、混合流速和体积含水率对超高含水原油初始沉积过程的影响,分析不同温度下原油的运动形态和初始沉积方式。初始沉积过程可分为蔓延沉积过程和粘连沉积过程,根据沉积特点和压降曲线的变化趋势将初始沉积过程分为3个阶段:沉积诱导期、快速沉积期和沉积动态平衡期。通过对沉积物碳数分布的分析,得知超高含水原油初始沉积过程中,同时存在剪切剥离作用、胶凝作用和分子扩散作用。实验温度和体积含水率主要通过改变胶凝作用和分子扩散来影响初始沉积过程,混合流速通过改变剪切剥离强度来影响初始沉积过程。  相似文献

This case study explores how a group of Grade 9 students engaged in sociopolitical discourses and actions in a science class in a mostly indigenous student school in Nepal. The study used sociopolitical consciousness (SPC) as a framework to document and understand indigenous students’ SPC-oriented science interactions and subsequent social change actions. We used ethnographic methods of data collection over 6 months. The study focused on the actions of 4 girls and 2 boys belonging to the indigenous Tharu group. Data were analyzed using iterative qualitative methods. The study findings show that students are capable of engaging in critical thinking, critical reflecting, and taking actions for social change. Additionally, students are competent to link their experiences with social, structural, and political discrimination to the relevant science content they learn. The study presents four thematic findings related to SPC and science teaching and learning: Fostering social justice awareness in science class, fostering structural understanding of inequities in sickle cell disease, fostering sociopolitical actions for sickle cell disease, and the teacher's activist pedagogy for SPC in science learning. Implications of the study are that culturally relevant pedagogy helps indigenous students to become sociopolitically more aware of the links between science and social change. Adding aspects of critical pedagogies in science teaching could encourage students to become more sociopolitically reflective about science learning.  相似文献

School psychologists are well-positioned to change the educational landscape for twice-exceptional students, or those who possess high ability in one or more talent domains along with one or more disabilities. Better understanding of the nuanced cognitive and psychosocial assessment patterns within this population may increase well-needed participation in gifted education opportunities and the likelihood of receiving accommodations, as well as decrease missed diagnoses. Based on our review of the empirical literature within domains of twice-exceptionality (e.g., attention deficit hyperactivity disorder, autism spectrum disorder, and specific learning disability), we provide recommendations for how school psychologists can interpret formative and summative assessments taken by twice-exceptional students and subsequently help design educational plans that will meet their unique needs.  相似文献

高危险性体育项目相对一般体育项目而言,是具有危险性大、专业技术性强、安全保障要求高等特点的体育活动。我国对高危险性体育项目有一定的法律规制,但存在顶层设计缺失、法律制度之间的冲突与不一致、可操作性不足等问题。这些制度缺陷产生的根源在于对立法必要性的认识不足、立法不作为,缺乏有效的立法监督机制等,现有制度的缺陷与不足会影响我国高危险性体育项目的发展,难以满足人们体育文化活动的需要。鉴于此,我国应逐步完善高危险性体育项目的法律规制,包括完善高危险性体育项目的审定主体,明确经营高危险性体育项目的主体范围、完善高危险性体育项目的行政许可条件、强化高危险体育项目行政监管以及风险防范等。  相似文献

This real‐data‐guided simulation study systematically evaluated the decision accuracy of complex decision rules combining multiple tests within different realistic curricula. Specifically, complex decision rules combining conjunctive aspects and compensatory aspects were evaluated. A conjunctive aspect requires a minimum level of performance, whereas a compensatory aspect requires an average level of performance. Simulations were performed to obtain students' true and observed score distributions and to manipulate several factors relevant to a higher education curriculum in practice. The results showed that the decision accuracy depends on the conjunctive (required minimum grade) and compensatory (required grade point average) aspects and their combination. Overall, within a complex compensatory decision rule the false negative rate is lower and the false positive rate higher compared to a conjunctive decision rule. For a conjunctive decision rule the reverse is true. Which rule is more accurate also depends on the average test reliability, average test correlation, and the number of reexaminations. This comparison highlights the importance of evaluating decision accuracy in high‐stake decisions, considering both the specific rule as well as the selected measures.  相似文献

ABSTRACT

Many museums are housed in historic buildings, sometimes the building itself is part of the museum collection. Creating a stable environment by providing a nearly constant temperature and relative humidity at correct levels decreases the risk of object degradation. Maintaining this steady indoor environment, however, increases energy consumption and risks to the historic building. Museum display cases offer a solution to the mitigation of risks to which valuable objects may be subjected by providing an extra layer of protection to indoor climate fluctuations. The Anne Frank House is a historic house museum located in Amsterdam. The museum has undergone several renovations in the last years to deal with an increase in the number of visitors to over 1.2 million a year. The original diaries and other documents of Anne Frank are permanently on display in the Anne Frank House. With the recent refurbishment the possibility arose to design a new state-of-the-art display case. This study presents the results of the experimental research related to the design, performed in-situ. The temperature and relative humidity in the new exhibition space and inside the new display cases were monitored to gain insight into the hygrothermal behavior of these controlled environments. A complementary numerical study was performed to investigate effects of dynamic climate control of the exhibition gallery and climate conditions in the display case under various circumstances. Four main conclusions are presented in this paper. The investigated display case design is able to provide a stable relative humidity environment by means of silica gel, while using an active box-in-box climate control system to create stable temperature conditions. The inner case temperature depends on the temperature supplied by the display case air handling unit. Protocols must be in place in case of malfunction or failure of the climate control system of the display case. The air handling unit of the case needs to be shut off to create a passive environment for the objects on display until necessary actions are taken. Exhibition gallery set points can be less stringent when susceptible museum objects are on display in the display case. The environments are separated and provide an opportunity for energy saving set point strategies. The last conclusion drawn is that the numerical study provides valuable insight into imposing dynamic control of set points for temperature and relative humidity in the exhibition gallery and the effect on the display case environment.  相似文献
