Improving Teaching Effectiveness by Scientific Research:Incorporate Novel Analytical Methods into Teaching of Instrumental Analysis
Keeping up with the subject development, novel analytical methods and research results developed in recent years are incorporated into classic instrumental analysis courses as supplementary teaching materials. Novel analytical methods such as colorimetric assay based on gold nanoparticle, fluorescent analysis based on quantum dot, sample pre-treatment methods based on molecularly imprinted polymer are introduced in teaching, beneficial to expanding the students' knowledge, improving the students' interest, increasing students' confidence and improving the teaching effectiveness.
Reform and Practice on Classroom Teaching of Chemistry Didactics in Normal College
Chemistry didactics is a compulsory specialty course with pedagogic characteristics and related with chemistry teaching in basic education. However, it is neglected by students in normal university. So,classroom teaching reform for chemistry didactics in Inner Mongolia Normal University is practiced from three ways respectively,which are teaching contents, teaching modes and teaching evaluation. Some effective functions are obtained, which facilitate the positivity and participation of students in classroom, and improve the teaching skills of students.
Exploration of “Quaternity” Practice Teaching Mode for Chemical Engineering Specialty in Local College
According to problems presently existed in practice teaching of chemical engineering specialty in local college, combined with the reality of local college, the practice teaching mode integrating intramural classroom experiments, intramural simulated practices, intramural base practices and off-campus base practices is presented, which has characteristics such as combining inside with outside, combining reality with simulation, steady progress, etc. Through exploration and practice,an unique local college practice teaching way is formed, which has positive significance on promoting competitiveness of local college.
Research on Teaching Mode of College Science Education Integrated with Green Ecology Education
Nowadays, energy saving and low-carbon living is the main theme of social life, higher education should also undertake the obligation. College science education integrated with green ecology teaching mode includes green classroom teaching mode, green experiment teaching mode, tutorial management mode, green ecological education practice mode and a variety of activities on eco-style green education theme.
New College Chemistry Experiment:One-pot Synthesis of Hantzsch Esters 1, 4-Dihydropyridines in Water
A series of Hantzsch esters 1,4-dihydropyridines with bioactive and biomedical property were synthesized by one-pot method in water using aromatic aldehyde, ethyl (methyl) acetoacetate and ammonium carbonate as starting materials and polyethylene glycol-400 (PEG-400) as phase transfer catalyst. The effects of different factors were investigated such as ratio of raw materials, reaction temperature, solvent and ratio of phase transfer catalyst. Reaction time was confirmed using thin layer chromatography (TLC), ammonium salts were also studied and the optimum experiment conditions were decided. The method has the advantages of good yields, less pollution and friendly environment. The structures of final products were characterized by FT-IR and 1H NMR.
Improved Method of Indicating the End of Sodium Nitrite Titration Method
Currently,indicating the end of sodium nitrite method mostly use dead stop titration and external indicator method, the two methods have some defects in the actual operation process. During teaching practice, the end indication method is improved by combining internal indicator with external indicator. Improved method can make the relative average deviation smaller,and experiment operation more simple and faster, so the experiment becomes more economic and practical.
Improvement of Di-n-butyl Ether Preparation Experiment
The experiment of preparing di-n-butyl ether has been improved: the amount of sulfuric acid is cut down suitably, the way of adding n-butyl alcohol is changed, the temperature of reaction end is risen,and the yield of di-n-butyl ether is increased. Moreover,effect of removing n-butyl alcohol from the crude product by saturated calcium chloride solution washing is poor,and better effect is obtained by 50% sulfuric acid washing.
Teaching Reform of Analytical Chemistry Course Based on CDIO Education Mode
Under the guidance of CDIO engineering education mode, the teaching methods of analytical chemistry course and the level of practical talents were improved. Students' professional consciousness were aroused and their learning orientation were strengthened. By decomposing the knowledge of the course unit, establishing the basic knowledge and skills standard, designing the teaching link of training project and comprehensive application, and implementing effective evaluation mechanism, students' learning initiative and team work spirit were improved. Meanwhile, teachers' ability was also promoted. The teaching reform can meet the need of professional course construction and improve teaching efficiency and quality.
Research on Biochemistry Teaching in Pharmaceutical Engineering
Biochemistry is an important course in pharmaceutical engineering. Combined with the specialty properties, society demand and teaching experiences on biochemistry in pharmaceutical engineering, some teaching methods were explored and summarized in this paper. It will lay a foundation to improve the teaching quality of biochemistry in future.
Teaching Reform of Instrumental Analysis Based on Different Majors
Instrumental analysis is one of the basic courses in many majors. In Northeast Forestry University, the course of instrumental analysis is not only the basic course for the majors of chemistry, chemical engineering and technology and applied chemistry, but also the basic course or major elective course of the majors of materials chemistry, light chemical engineering, chemistry processing of forestry products and environmental science. In order to meet the needs of different majors' feature and background,teaching of the instrumental analysis had been reformed on both the theory and experiment.
Study on Improving the Innovation Vigor of Postgraduate of Chemistry
Innovation capability cultivating is core of postgraduate education and one of the important tasks of colleges. A series of measures to improve postgraduates' innovation vitality are given, such as reform of training mode, assessment mechanism, creative practice activities and tutor team, which has obtained satisfactory results.
The Inspiration on Domestic Physical Chemistry Teaching from Teaching Method of Colloid and Interface Chemistry in Norwegian University of Science and Technology
Colloid and interface chemistry is an important branch of physical chemistry. The author summarizes the unique teaching idea and method in colloid and interface chemistry teaching of famous Professor Johan Sjöblom, which will enlighten and improve the teaching quality of physical chemistry in China.
