Abstract:

STEM is a type of educational concept based on multi-disciplinary integration of science, technology, engineering and mathematics, which has become a focus of international education research and reform. It aims to cultivate the students' ability of asking, analyzing and solving problems, and stimulate students' spirit of scientific exploration and innovative thinking by merging the multidisciplinary knowledge. In this paper, educational concept of STEM is introduced into the course of analytical chemistry experiment teaching, and a new teaching mode of analytical chemistry experiment course is explored. It is advocated to take students as the center and take real problems as the guide to cultivate students' scientific exploration and practice ability. Students can independently complete a series of analytical chemistry experiment via resorting relevant courses theory, experimental scheme design, experimental process and result analysis. A new teaching mode of analytical chemistry experiment is investigated from three aspects including course content, teaching methods and assessment methods, so as to improve the teaching quality of analytical chemistry experiments and students' learning interest and scientific literacy.

Key words: Analytical chemistry experiment, Educational concept of STEM, Scientific literacy, Creativity
