Abstract:

Failed experiments occur frequently in laboratory. How the laboratory teacher actively and effectively deal with the failed experiments and guide students plays an important role in the cultivation of undergraduates' creativity. If he loses on the swings, he may win on the roundabouts. We show how teacher guide and enlighten the undergraduate students to get the inspiration and learn from the failed experiments by two examples of Chemistry Laboratory of undergraduates. Let the students find problems with curiosity, analyze problems, and solve the problem in the "experiment-failure-improvement-experiment" process based on relevant knowledge and rules. The teaching and learning efficiency of laboratory class is significantly improved. Undergraduates not only have a profound discussion and analysis of experimental results, but also receive effective training in scientific research literacy and quality.
