文摘Practical activities are an indispensable piece of science education.As such,assessment of these practical activities is vital for continually enhancing the quality of science instruction.This article presents a tentative framework structured for assessing practical activities in science education.The proposed framework is built upon seven components:engagement and participation,relational thinking,stepwise mastery,contextualization,multidimensional integration,empowerment,and scientific articulacy.The framework might provide science educators with an alternative lens through which to enhance the effectiveness of practical activities,promote student engagement,and better prepare learners for the future.This framework is designed to be additive and complementary to existing assessment approaches and can be adapted and customized to suit specific local contexts and varying grade levels by science educators in the pursuit of excellence in an ever-evolving science education landscape.
文摘Background:Stretching has wide appeal,but there seems to exist some mismatch between its purported applications and what the evidence shows.There is compelling evidence for some stretching applications,but for others,the evidence seems heterogeneous or unsupportive.The discrepancies even affect some systematic reviews,possibly due to heterogeneous eligibility criteria and search strategies.This consensus paper seeks to unify the divergent findings on stretching and its implications for both athletic performance and clinical practices by delivering evidence-based recommendations.Methods:A panel of 20 experts with a blend of practical experience and scholarly knowledge was assembled.The panel meticulously reviewed existing systematic reviews,defined key terminologies(e.g.,consensus definitions for different stretching modes),and crafted guidelines using a Delphi consensus approach(minimum required agreement:80%).The analysis focused on 8 topics,including stretching's acute and chronic(long-term)effects on range of motion,strength performance,muscle hypertrophy,stiffness,injury prevention,muscle recovery,posture correction,and cardiovascular health.Results:There was consensus that chronic and acute stretching(a)improves range of motion(although alternatives exist)and(b)reduces muscle stiffness(which may not always be desirable);the panel also agreed that chronic stretching(c)may promote vascular health,but more research is warranted.In contrast,consensus was found that stretch training does not(a)contribute substantively to muscle growth,(b)serve as an allencompassing injury prevention strategy,(c)improve posture,or(d)acutely enhance post-exercise recovery.Conclusion:These recommendations provide guidance for athletes and practitioners,highlighting research gaps that should be addressed to more comprehensively understand the full scope of stretching effects.
文摘Outer-independent Roman domination on graphs originates from the defensive strategy of Ancient Rome,which is that if any city without an army is attacked,a neighboring city with two armies could mobilize an army to support it and any two cities that have no army cannot be adjacent.The outer-independent Roman domination on graphs is an attractive topic in graph theory,and the definition is described as follows.Given a graph G=(V,E),a function f:V(G)→{0,1,2}is an outer-independent Roman dominating function(OIRDF)if f satisfies that every vertex v∈V with f(v)=0 has at least one adjacent vertex u∈N(v)with f(u)=2,where N(v)is the open neighborhood of v,and the set V0={v|f(v)=0}is an independent set.The weight of an OIRDF f is w(f)=∑_(v∈V)f(v).The value of minf w(f)is the outerindependent Roman domination number of G,denoted asγoiR(G).This paper is devoted to the study of the outer-independent Roman domination number of the Cartesian product of paths P_(n)□P_(m).With the help of computer,we find some recursive OIRDFs and then we present an upper bound ofγoiR(P_(n)□P_(m)).Furthermore,we prove the lower bound ofγoiR(P_(n)□P_(m))(n≤3)is equal to the upper bound.Hence,we achieve the exact value ofγoiR(P_(n)□P_(m))for n≤3 and the upper bound ofγoiR(P_(n)□P_(m))for n≥4.
基金Ministry of Education Supply and Demand Matching Employment Education Project,“Exploration and Practice of School-Enterprise Co-Education of Surveying and Mapping Professionals Under the Background of Industry-Education Integration”(Project No.:2024010250340)。
文摘To promote the achievement of high-quality and full employment goals for students in higher education,this paper analyzes the integration path of practical education and teaching in civil engineering and transportation majors,guided by surveying employment.This paper proposes three integration paths for practical teaching and education in civil engineering and transportation majors under the employment orientation.The first path is to create a modularized and informatized curriculum system.The second path is to deepen diverse cooperative practices between schools and enterprises.The third path is to construct a diversified quality evaluation system for academic achievement.To ensure the quality of education and employment,schools should continuously evaluate and reflect on the practical effects of these three paths to further optimize them.
基金The Second Batch of Comprehensive Reform and Quality Construction Projects of Party Building and Ideological and Political Education in 2024“Research on the Growth Patterns and Training Path of Excellent Counselors in Private Colleges”(HKDS2024YB11)。
文摘With the rapid development of private higher education,the construction of counselor teams in private universities has become increasingly important.This paper focuses on outstanding counselors in private universities,delving into their growth patterns and proposing targeted training paths based on this analysis.By reviewing relevant theories and analyzing case studies of excellent counselors,it is found that outstanding counselors in private universities exhibit stage-specific characteristics during their development,influenced by personal traits,school environment,career progression,and other factors.In terms of training approaches,efforts should be made to improve selection mechanisms,strengthen training systems,provide career development support,and create a positive work atmosphere,all aimed at enhancing the overall quality of the counselor team in private universities and better serving student growth and institutional development.
