| 1 | Exploration and Practice of Database System Course Based on KAPI Teaching Modality Under the Emerging Engineering Education显示文摘Nowadays,it is extremely urgent for the software engineering education to cultivate the knowledge and ability of database talents in the era of big data.To this end,this paper proposes a talent training teaching modality that integrates knowledge,ability,practice,and innovation(KAPI)for Database System Course.The teaching modality contains three parts:top-level design,course learning process,and course assurance and evaluation.The top-level design sorts out the core knowledge of the course and determines a mixed online and offline teaching platform.The course learning process emphasizes the correspondence transformation relationship between core knowledge points and ability enhancement,and the course is practiced in the form of experimental projects to finally enhance students’innovation consciousness and ability.The assurance and evaluation of the course are based on the outcome-based education(OBE)orientation,which realizes the objective evaluation of students’learning process and final performance.The teaching results of the course in the past 2 years show that the KAPI-based teaching modality has achieved better results.Meanwhile,students are satisfied with the evaluation of the modality.The teaching modality in this paper helps to stimulate students’initiatives,and improve their knowledge vision and practical ability,and thus helps to cultivate innovative and high-quality engineering talents required by the emerging engineering education. | Hongqi Li Kexin Sun Wei Lu Yong Li Chunyan Ma Hongping Gan | 2023 | 计算机教育2023，，12： | 0 |
| 2 | Rcm2IT: Informatization Teaching Using Refined Classroom Management of Students’ Learning Process显示文摘In this paper,we propose an iterative,problem-and task-driven refined classroom management method for informatization teaching,dubbed Rcm2IT,based on data analysis of students’learning process.More specifically,Rcm2IT firstly classifies the teaching resources and elements in the unit of classroom sections,and designs the corresponding fine-grained templates and examples of teaching elements.Meanwhile,Rcm2IT divides students into different levels according to their previous classroom performance,and teaches students at different levels according to their aptitude.Finally,we implement the refined classroom management and assessment of students’learning process via our customized precise micro classroom platform(PMcP)based on the previous two stages.The designed PMcP can carry out real-time analysis and teaching evaluation,objectively and accurately measure and feedback the students’learning results,further iteratively optimize the teaching objectives.The course practice in“digital image processing”shows that Rcm2IT can not only support teachers to dynamically adjust the teaching content,but also teach students according to their aptitude,and improve the teaching quality and efficiency. | Hongping Gan Chunyan Ma Jun Shu Lipeng Gao Tao Zhang Xikang Feng | 2022 | 计算机教育2022，，12： | 0 |
| 3 | Research and Practice of Hybrid Teaching for Software Testing based on Interactive Learning显示文摘To address the problems of insufficient number of personalized exercises and cases and teachers’lack of grasp of students’weak knowledge points in the current software testing online courses,we study the strategy of establishing and updating intelligent exercise sets and case libraries and analyze the answers and dig out the weak points of knowledge through group intelligence reasoning and interactive machine learning methods.This will help teachers to make uniform and targeted explanations,reduce manual judgment,and achieve intelligent teaching quality reform,and implement the educational concepts of“keeping up with the times”and“teaching according to students’abilities”. | Lipeng Gao Wei Zheng Hongping Gan Depeng Gao Xikang Feng | 2021 | 计算机教育2021，，12： | 0 |
| 4 | Studies on reaction mechanisms and distinct chemiluminescence from cyanoimino neonicotinoids triggered by peroxymonosulfate in advanced oxidation processes显示文摘In this study, we proposed a novel method to investigate the advanced oxidation process of neonicotinoids(NNIs) from the perspective of concomitant chemiluminescence(CL) reaction. It was found that in the presence of cobalt ions with cyanoimino NNIs, acetamiprid(ACE) and thiacloprid(THI), could promote peroxymonosulfate and Ru(bpy)_(3)^(2+) to produce strong CL, but no CL occurred with nitro-involved NNIs as alternatives. Experimental dada from UV absorption spectra and chemiluminescence spectra suggested that new cyclic compounds might be formed during the reaction. Based on the results of free radical scavenging experiment and mass spectra, a new degradation and reaction mechanism of cyanoiminocontaining NNIs was proposed. ACE or THI were first attacked by SO_(4)^(·-) to form benzyl radicals, which in turn reacted with the carbon atoms of cyano group through electrophilic addition reaction in the formation of intramolecular ring. Then a redox reaction between Ru(bpy)_(3)^(3+) and imino group immediately took place with CL emission(610 nm). The new mechanistic knowledge would be meaningful for other contaminants for their interactions with PMS. | Mengdie Cai Weimin Gan Zhiqin Ding Hongping Cai Lijun Wei Xianglei Cheng | 2023 | Chinese Chemical Letters2023，34，3： | 0 |
| 5 | A new series of two-photon polymerization initiators:Synthesis and nonlinear optical properties显示文摘Four photopolymerization initiators with D-π-D (D,donor; π,conjugation system) structure have been synthesized by solvent-free reaction and characterized by 1H NMR spectroscopy,IR and elemental analysis. The one-photon and two-photon excited fluorescence have been investigated in different solvents. Experimental results of the one-photon and two-photon absorption cross sections show different trends in OPA and TPA ability with different substitution groups in donor units. | GAN XiaoPing ZHOU HongPing SHI PengFei WANG Peng WU JieYing TIAN YuPeng YANG JiaXiang XU GuiBao ZHOU YuFang JIANG MinHua | 2009 | Science China Chemistry2009，52，12： | 0 |
