摘要:

STEM是一种集科学、技术、工程、数学多学科融合的项目式教育理念,旨在通过融合多学科知识完成项目目标,从而培养学生提出问题、分析问题以及解决问题的能力,进而激发学生的科学探索精神和创新思维能力,已经成为当前国际教育研究和改革的热点。本文将STEM教育理念引入分析化学实验教学过程中,探索发展分析化学实验课程教学新模式。倡导以学生为中心、以真实问题为牵引,学生以相关课程理论为线索,自主完成实验方案设计、实验过程、实验结果分析等一系列分析化学实验过程,从而培养学生的科学探索与实践能力。主要从课程内容、教学方法以及考核方式等三个方面来探索分析化学实验教学新模式,进而提高分析化学实验的教学质量和学生的学习兴趣和科学素养。

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.
