Chemistry is an undergraduate major in colleges and universities, which belongs to chemistry major. The basic study period is four years, and the degree of science is awarded.
On the basis of systematically and solidly mastering the basic knowledge, basic theory and basic skills of chemistry, chemistry majors should also master the basic methods and means of chemical research, have a strong sense of innovation and practical ability, deeply understand the frontier and development trend of chemistry, and understand the basic knowledge of life, materials, energy, environment and other related disciplines, so as to be able to engage in scientific research, technology and education in chemistry and related fields.
Professional training objectives
Chemistry majors train talents who have a high sense of social responsibility, good scientific and cultural literacy, better grasp the basic knowledge, basic theories and skills of chemistry, have innovative consciousness and practical ability, and can engage in scientific research, technological development, education and teaching of chemistry and related disciplines.
According to the above-mentioned training objectives and self-orientation, combined with the characteristics of their own disciplines, and on the basis of full investigation and analysis of industry and regional characteristics and students' future development needs, colleges and universities should accurately locate and refine the connotation of talent training objectives to meet the needs of national and social development for diversified talents.
Colleges and universities should also regularly evaluate the consistency of talent training objectives with the needs of sustainable development of science and technology, economy and society, and establish an effective mechanism to adjust the professional development orientation and talent training objectives in time. Master the basic methods and means of chemical research or chemical design, development, inspection and production, and have the preliminary ability to discover, propose, analyze and solve problems in chemistry and related disciplines.
