探索以“霍乱弧菌检测虚拟仿真实验”为载体的混合式实验教学模式

虚拟仿真实验是一种现代信息化和智慧教学的重要方法,对高等医学院校教学质量的发展起到重要的推进作用。我们自主开发建设的“霍乱弧菌检测与防控虚拟仿真实验”,既弥补了因生物安全问题不能开展的实验教学,也解决了微生物学检验实验教学中存在的操作标准化问题。采用“三步进阶”混合教学模式,实现以“学生为中心”的师生互动模式,创建“设计性实验报告”,与育人元素有机结合,培育医学生的职业使命感。细化考核标准,实现过程性评价。探索课前启发铺垫、课中内化升华、课后巩固拓展混合式实验教学模式,有效提高学生的实验技能,实现知行合一、素能共育的教学目标。     

“强基计划”背景下生物学实验教学改革——以“生物学综合设计”课程为例北大核心CSCD

人才培养是未来国家竞争的核心。“强基计划”是我国对基础学科拔尖创新人才培养模式的重要探索,是满足国家重大战略人才需求的重要举措。“强基计划”招收的学生,往往成绩优异、兴趣浓厚,这为相关学科的人才培养模式提出了新要求和新目标。其中,“强基计划”背景下的基础教学改革势在必行。超学科教育理念(science,technology,engineering,arts,mathematics,STEAM)作为一种跨学科的综合性教育理念,与“强基计划”的建设理念不谋而合。鉴于此,天津大学生命科学学院根据“强基计划”背景下生物学科人才培养目标,结合STEAM教育理念,以“生物学综合设计”课程为例,对生物学实验教学改革进行了探索与实践。

教学医院毕业实习教学管理模式的实践探索

目的 分析高校附属医院临床医学专业应届毕业生对毕业实习教学管理的满意度,为完善毕业实习教学管理模式提出对策。为提高毕业实习教学水平和学生整体素质教育提供参考。 方法 制定学生对教师、教师对学生、学生对教学资源的评价指标,对临床医学专业应届毕业生、实习带教老师进行问卷调查。 结果 教师对学生“学习态度”“独立完成操作”的满意度均高于95%;学生对教师教学纪律、教学准备、和教学能力的满意度均达到100%;学生对设备准备、耗材准备、毕业实习学时安排满意度均高于95%。发现了医学生毕业实习管理工作中存在的具体问题。结论 高校附属医院要建立完善毕业实习管理制度,加强毕业实习质量监督,科学制定考核制度。     

Model-based predictions of anaerobic digestion of agricultural substrates for biogas production

A modified Anaerobic Digestion Model No. 1 (ADM1), calibrated on a laboratory digester with a feeding mix of 30% weight of cow manure and 70% weight of corn silage, was implemented, showing its performances of simulation as a decision-making and planning-supporting tool for the anaerobic digestion of agricultural substrates. The virtual fermenter obtained was used to conduct simulations with different feeding compositions and loading rates of cow manure, corn silage, grass silage and rape oil. All simulations were started at the same initial state which was represented by a steady state with an organic loading rate of 2.5 kg ODM/(). The effects of the different feeding combinations on biogas composition and biogas yield were predicted reasonably, and partly verified with the available literature data. Results demonstrated that the simulations could be helpful for taking decisions on agricultural biogas plant operation or experimental set-ups, if used advisedly.     

Techno-economical study of ethanol and biogas from spruce wood by NMMO-pretreatment and rapid fermentation and digestion

Given that N-methylmorpholine-N-oxide (NMMO) is a promising alternative for the pretreatment of lignocelluloses, a novel process for ethanol and biogas production from wood was developed. The solvent, NMMO, is concentrated by multistage evaporation, and the wood is pretreated with the concentrated NMMO. Thereafter, ethanol is produced by the non-isothermal simultaneous saccharification and fermentation (NSSF) method, which is a rapid and efficient process. The wastewater is treated by upflow anaerobic sludge blanket (UASB) digester for rapid production of biogas. The process was simulated by Aspen plus®. Using mechanical vapor recompression for evaporators in the pretreatment and multi-pressure distillation columns, the energy requirements for the process were minimized. The economical feasibility of the developed biorefinery for five different plant capacities was studied by Aspen Icarus Process Evaluator. The base case was designed to utilize 200,000 tons of spruce wood per year and required M€ 58.3 as the total capital investment, while the production cost of ethanol is calculated to be €/l 0.44.
