通过教学过程和互动设计保障在线教学的效果

Based on the analysis of the courses and the investigation of students' online learning needs, an online teaching mode of "Tencent Classroom" and "Rain Classroom" with "split screen" is designed. This mode is used for the online teaching of "Foundation of Innovation and Entrepreneurship" and "Chemical Instrumentation and Automation". After two months of teaching practice, the teaching and learning were reflected and summarized, aiming to improve the performance of online teaching.     

硅藻土增强橡胶复合材料的研究进展

硅藻土是单细胞硅藻的遗骸经自然条件形成的硅质沉积岩,因其具有质轻、大的比表面积、超强的吸附性、隔音、耐磨、耐热以及耐腐蚀等特点而被广泛应用于化工、石油、建材、生物医药卫生以及环保等众多领域。然而由于硅藻土与白炭黑的结构成分相似,白炭黑通常用作橡胶的补强填料,目前硅藻土用于橡胶补强填料的研究鲜少报道。本文综述了硅藻土的性能、硅藻土的国内外研究现状、硅藻土的改性以及硅藻土增强橡胶复合材料的制备过程,并对硅藻土增强橡胶复合材料的发展趋势做了展望。

“双一流”背景下高等农业院校有机化学基础课程教学新模式的构建及实践

The crop science of Sichuan Agricultural University is an authorized first-class discipline. As the strategic supporting department for innovative talent cultivation in agriculture and forestry major, we are facing a long-term challenge in reforming the teaching mode for basic course-organic chemistry and cultivating talented students with solid basic knowledge and strong sense of innovation. Herein a thorough survey was performing to establish the executable teaching programs for this course during the "Double-First Class Universities Plan" period. A multidimensional teaching resource library for organic chemistry course was also constructed. The new classroom teaching mode "Interest cultivation-Creative thought development-Autonomous and Cooperative learning", along with a stepwise practice teaching mode "Foundation skills-Integrated application-Innovative trial" was proposed and practiced among thirty-five majors including agriculture, forestry and veterinary, to improve the quality for innovative talent cultivation and support our first-class discipline construction. This research could probably serve as a reference for congeneric agricultural university.
