General Chemistry Experiment carried out to improve innovation ability of students
The contents of the progress of chemistry, most of the content comes from the experimental results of scientific research, can help students understand the various branches as soon as the international frontier and hot, the students will conduct research to help. (3) practicality: the object is a real test sample,moncler outlet, for example, Dongli Lake water quality, Chaozhou, preserved fruits, specialty fruit, shrimp shell and so on. Product of the experiment is useful products, such as ferric sulfate, zinc gluconate, cationic starch, antioxidants, food preservatives, such as titanium dioxide Preparation and Characterization. (4) universality: an experiment can be achieved by \the determination of molecular sieve preparation and determination of properties and so on. 3 to improve teaching effectiveness of various teaching methods to improve the teaching of the flexible use of teachers to play a leading role in the same time, bring into full play the main role of students as to create conditions for the active participation of students, guide students to think, explore and discover, improve their test enthusiasm,p90x calendar, have a multiplier effect. (1) heuristic teaching. Heuristic by the tutor to explain the experimental test the basic principles and basic theory, to guide students access to literature, comprehensive analysis of related knowledge to design experiments after the initial program, and then ask students to access literature, comprehensive analysis and comparison, to determine the design of the experimental program , reviewed by the tutor. (2) discussion teaching. Integrated in the teaching experiment, using methods inspired students to question what instruments, what kind of methods through the completion of the experiment content, let students experiment summarized the basic steps, ideas and features. Facilitate the students have a more complex experimental substantive understanding of theoretical knowledge to encourage students to enhance learning, promote student self-awareness. For the practical content of a strong comprehensive experiment, to arrange for students learning, then teachers in the classroom to tell you, we then discuss, analyze and evaluate experimental subjects to find a solution from the most concise experimental procedures J. (3) combination of Class Teaching. Establish an open platform for laboratory experiments, so that the students both in the classroom learning outside the classroom can also practice at any time the content of classroom exercises, exercise, hands-on skills. General Chemistry Experiment 4, the comprehensive evaluation results to improve the quality of experimental teaching,uggs ireland, in addition to the above measures, but also test for the evaluation of links should be strengthened, so that students attach great importance to experiment. General Chemistry Experiment results of the assessment can be divided into three parts: research design, 20%, independent access to experimental subjects require students to nearly 5 years of literature, the system detailed experimental program; experimental operation accounted 4O%, requires students in accordance with the experimental program, self-completion of the pilot process, including the assembly of experimental equipment, solution configuration and calibration, etc. make accurate records of all experimental data and phenomena, guidance teachers should be fully supervision; lab reports 40% completion, students analyze and process the experimental results After writing a complete lab report, guidance teachers graded according to the experimental results. 5 Conclusion chemical experiment teaching through comprehensive reform, I deeply appreciate the comprehensive experiment is to develop creative ability and practical ability of the excellent way. It is essential to an undergraduate experimental course, is the basic experiment, intermediate experiment and not be replaced by thesis. General Chemistry Experiment enable students to learn knowledge from books can not go to school, and enhance the abilities of students and innovation. In short,ghd haarglätter, to carry out comprehensive experimental teaching, research more conducive to cultivate awareness and research capacity with the compound talents, high-quality personnel to adapt to modern society's requirements.
