标题： Improving Student's Lab Practices: the Performance Grade

摘要： 在学生中培养良好的实验室工作态度是一项困难但非常重要的任务，尤其是在第一层次的课程中。 在实验课期间观察工作实践的基础上引入一个成绩，可以对获得不仅包括技术方面，还包括独立性和团队合作的积极技能产生显著的有益影响。 给出了具体的建议，以根据特定观察结果来确定成绩，并进行了定量分析，以确保绩效成绩的较高内在波动性不会影响最终的实验成绩。 显示英文摘要

摘要： Instilling good laboratory working attitudes in students is a difficult but very important task, especially in the first level courses. The introduction of a grade, based on the observation of work practices during laboratory sessions, can be strongly beneficial towards the acquisition of positive skills covering not only the technical aspects, but also the acquisition of both independence and team work. Explicit suggestions are given for basing the grade on specific observations and a quantitative analysis is performed to guarantee that the higher intrinsic volatility of the Performance Grade does not affect the final laboratory grade.
