文摘Chemistry science popularization for lower grades(Grades 1-2)in primary schools is an important part of science enlightenment education.However,in practice,it generally faces practical dilemmas such as insufficient content adaptability,a single implementation method,and a lack of coordination mechanisms.Based on Piaget’s Cognitive Development Theory and the STSE(Science,Technology,Society,Environment)educational concept,this study constructed a four-in-one strategy system of“content development-teaching implementation-collaborative linkage-guarantee support”through literature analysis,action research,and empirical comparison.An empirical study was conducted in two primary schools for one academic year.The results show that this strategy system can increase students’interest in participating in chemistry science popularization by 42 percentage points,the compliance rate of observation ability reaches 85%,and the collaborative participation of families,schools,and society rises to 85%.The core strategies formed in the study,including“age-appropriate content screening,interactive teaching implementation,three-dimensional collaborative promotion,and full-process guarantee support,”provide a replicable practical model for the standardized and efficient development of chemistry science popularization for lower grades in primary schools.They also offer empirical references for fulfilling the requirement of“strengthening the pertinence and effectiveness of science popularization”in the Law of the People’s Republic of China on Popularization of Science and Technology(revised in 2024).

文摘Objective:This study aimed to explore the strategies used by acute care hospitals in implementing a national standard for comprehensive care.Methods:A qualitative descriptive study was conducted with 28 care professionals(20 nurses,two doctors,and six allied health professionals)recruited from a broad range of Australian acute care hospitals.Data were collected using semi-structured interviews from March to August 2023.The interviews were audio-recorded,transcribed,and thematically analyzed.Results:Strategies for implementing the Comprehensive Care Standard(CCS)vary,even within a health service organization.We identifiedstrategies hospitals used regarding the implementation team and plan,communication,education and training,documentation system,patient care plan,networking,incentives and pressure,feedback,and reflectingand evaluating.Conclusions:This interview study sheds light on the various strategies adopted by hospitals in implementing the CCS,providing a practical foundation to inform implementation efforts both within Australia and internationally.
文摘Within the perspective of curriculum-based ideological and political education,this paper takes a secondary vocational English reading class themed“Invention and Innovation”as an example to delve into the process from instructional content design to implementation.In terms of instructional design,the paper highlights key elements.Profoundly,it discusses the strategies for teaching implementation,including the setting of teaching objectives,the selection of reading instructional materials,and the design and advancement of teaching activities.The aim is to effectively integrate ideological and political elements into secondary vocational English reading instruction,with the hope of providing useful references and insights for the teaching of English reading in secondary vocational education.

文摘Our concern is to investigate controlled remote implementation of partially unknown operations with multiple layers.We first propose a scheme to realize the remote implementation of singlequbit operations belonging to the restricted sets.Then,the proposed scheme is extended to the case of single-qudit operations.As long as the controller and the higher-layer senders consent,the receiver can restore the desired state remotely operated by the sender.It is worth mentioning that the recovery operation is deduced by general formulas which clearly reveal the relationship with the measurement outcomes.For the sake of clarity,two specific examples with two levels are given respectively.In addition,we discuss the influence of amplitude-damping noise and utilize weak measurement and measurement reversal to effectively resist noise.

文摘This paper studies the problem of time-varying formation control with finite-time prescribed performance for nonstrict feedback second-order multi-agent systems with unmeasured states and unknown nonlinearities.To eliminate nonlinearities,neural networks are applied to approximate the inherent dynamics of the system.In addition,due to the limitations of the actual working conditions,each follower agent can only obtain the locally measurable partial state information of the leader agent.To address this problem,a neural network state observer based on the leader state information is designed.Then,a finite-time prescribed performance adaptive output feedback control strategy is proposed by restricting the sliding mode surface to a prescribed region,which ensures that the closed-loop system has practical finite-time stability and that formation errors of the multi-agent systems converge to the prescribed performance bound in finite time.Finally,a numerical simulation is provided to demonstrate the practicality and effectiveness of the developed algorithm.

文摘This paper investigates the adaptive fuzzy finite-time output-feedback fault-tolerant control (FTC) problemfor a class of nonlinear underactuated wheeled mobile robots (UWMRs) system with intermittent actuatorfaults. The UWMR system includes unknown nonlinear dynamics and immeasurable states. Fuzzy logic systems(FLSs) are utilized to work out immeasurable functions. Furthermore, with the support of the backsteppingcontrol technique and adaptive fuzzy state observer, a fuzzy adaptive finite-time output-feedback FTC scheme isdeveloped under the intermittent actuator faults. It is testifying the scheme can ensure the controlled nonlinearUWMRs is stable and the estimation errors are convergent. Finally, the comparison results and simulationvalidate the effectiveness of the proposed fuzzy adaptive finite-time FTC approach.
