文摘In order to improve the traditional teaching model of traditional Chinese medicine identification course for graduate students of pharmacy,this paper described the research on constructing and practicing the blended teaching model of"online+offline"based on the teaching concept of TfU by taking the course of"Authentic Medicinal Materials and Quality of Traditional Chinese Medicine"as an example.In the preparatory phase,through resource integration and course content decomposition,it identifies"generative topics"to engage students in pre-class online discussions.During the instructional phase,"comprehension-oriented objectives"are established based on learning analytics,followed by the implementation of"understanding-focused activities"for guided inquiry in offline classrooms.The post-class phase employs online extended materials to conduct"sustained assessment"through evaluations and summaries,thereby continuously optimizing subsequent teaching practices.This pedagogical framework not only effectively cultivates investigative research thinking among graduate students but also enhances standardized management and scientific development of the teaching team.The practical research outcomes and experiences derived from this model can provide valuable references for analogous course reforms.
基金phased research achievement of the Educational and Teaching Reform Research Project of Tangshan Normal University,titled“Construction and Practical Research on the Teaching Framework of College English Courses with Ideological-Political Elements under the Background of New Liberal Arts”(2023JG13).
文摘Courses with ideological-political elements are a new direction of the reform of higher education teaching in the new era and a key initiative to implement the fundamental task of“virtue-fostering through education.”College English,as a public basic course in universities,undertakes the dual missions of language teaching and ideological-political education,making it a primary platform for implementing courses with ideological-political elements.Based on the current teaching state of college English courses with ideological-political elements,this paper explores the blended teaching mode of college English courses with ideological-political elements by reconstructing teaching content,innovating teaching methods,integrating online and offline resources,and optimizing the teaching process,focusing on the three stages of pre-class,in-class,and after-class.
文摘Against the backdrop of the digital era,profound changes have taken place in the education industry.The development of information technology has affected the teaching of financial accounting majors in colleges and universities.The traditional teaching mode can hardly meet the needs of talent cultivation.Therefore,in the comprehensive practical training course of financial accounting,it is necessary to attach importance to the implementation of blended teaching,effectively innovate the teaching mode,and improve the effectiveness of talent cultivation.From the perspective of the comprehensive practical training course of financial accounting in colleges and universities,this paper analyzes the application value of blended teaching and puts forward specific teaching practice strategies,aiming to enhance the educational effect of the course and provide reference for the subsequent reform of professional courses.
文摘The current work includes a numerical investigation of the effect of biodiesel blends with different aluminum oxide nanoparticle concentrations on the combustion process in the cylinder of a diesel engine.IC Engine Fluent,a specialist computational tool in the ANSYS software,was used to simulate internal combustion engine dynamics and combustion processes.Numerical analysis was carried out using biodiesel blends with three Al_(2)O_(3) nanoparticles in 50,100,and 150 ppm concentrations.The tested samples are called D100,B20,B20A50,B20A100,and B20A150 accordingly.The modeling runs were carried out at various engine loads of 0,100,and 200 Nm at a rated speed of 1800 rpm.The combustion characteristics are improved due to the catalytic effect and higher surface area of nano additives.The results showed the improvements in the combustion process as the result of nanoparticle addition,which led to the higher peak cylinder pressure.The increases in the peak cylinder pressures for B20A50,B20A100,and B20A150 about B20 were 3%,5%,and 8%,respectively,at load 200 Nm.The simulation found that the maximum temperature for biodiesel blends diesel was higher than pure diesel;this was due to higher hydrocarbon values of B20.Also,nano-additives caused a decrease in temperatures in the combustion of biofuels.

文摘The recycling of cathode materials from spent lithium-ion battery has attracted extensive attention,but few research have focused on spent blended cathode materials.In reality,the blended materials of lithium iron phosphate and ternary are widely used in electric vehicles,so it is critical to design an effective recycling technique.In this study,an efficient method for recovering Li and Fe from the blended cathode materials of spent LiFePO_(4)and LiNi_(x)Co_(y)Mn_(1-x-y)O_(2)batteries is proposed.First,87%A1 was removed by alkali leaching.Then,91.65%Li,72.08%Ni,64.6%Co and 71.66%Mn were further separated by selective leaching with H_(2)SO_(4)and H_(2)O_(2).Li,Ni,Co and Mn in solution were recovered in the form of Li_(2)CO_(3)and hydroxide respectively.Subsequently,98.38%Fe was leached from the residue by two stage process,and it is recovered as FePO_(4)·2H_(2)O with a purity of 99.5%by precipitation.Fe and P were present in FePO_(4)·2H_(2)O in amounts of 28.34%and 15.98%,respectively.Additionally,the drift and control of various components were discussed,and cost-benefit analysis was used to assess the feasibility of potential application.
