Drug analysis is the use of chemical, physical, chemical or biochemical methods and techniques to study the chemical structure of synthetic drugs has made it clear or natural drugs and their preparations for quality control methods, but also a representative of the traditional Chinese medicine research and biochemical drugs and their preparations quality control methods River . Drug analysis is an "approach discipline ." In the learning process , it is difficult for students to grasp the characteristics and laws , difficult entry . How to improve the quality of teaching, teachers deserve careful study. 药品综合是使用化学、情理化学或者者生物化学的办法以及技能，钻研化学构造曾经经经明白的分解药品或者者自然药品及其药剂的品质掌握办法，也钻研有专人性的国药药剂以及理化药品及其药剂的品质掌握办法川。药品综合是一门“办法科学”。 One of the basic conditions of vocational schools 学校的基本状况 1.1 basis of poor students because education reform, the higher the quality of students admitted students are general high , vocational schools have lower entry requirements , poor quality of junior high school graduates enroll even some youth into the school community . Therefore, compared with the pre-1999 , the overall decline in the quality of students . 学员根底较差因为文化建制变革，生源品质较高的学员被普高登科，中职学校不能不升高退学环境，招收品质较差的初中卒业生以至全体政法成年入校。因而，同1999年先前比拟，学员的全体高素质会有偏差。 1.2 Student learning objectives are not clear, not high interest in learning enthusiasm of students is poor, subjective sleep, in the classroom distraction, lack of initiative to explore knowledge, learning behavior , a considerable part of the student teachers confined passive layout complete learning tasks, there are some students can not even complete. Therefore, teachers in the teaching process should be treated as such. 1.3 shackles of traditional concepts of education currently secondary vocational schools, classrooms still shackles of traditional concepts of education . Teachers in order to complete the required syllabus imparting knowledge , the teaching process is just one way teachers teach , students simply listening to the teacher to explain the lack of effective classroom , teachers and students practical cooperation mechanisms. Most teachers tend to teach middle- level students , there is no basis for targeted student status management at different levels , affecting teaching. 2 strengthen teachers' ability, to adapt teaching needs 2.1 Teachers should have a strong practical ability is given to the characteristics of vocational education . Vocational education targeted , application characteristics , emphasizing practical ability and entrepreneurial competency-based vocational ability. Schools should create a high-quality teachers , to sum up the experience in practice , improve teaching and practice of successful experience rose to a new theory , in order to better guide the teaching practice, so that teachers impart book knowledge is no longer a mechanical the " Jiaoshu Jiang ", but set teaching , research, management and other capabilities in a composite -type teachers. Teachers should have : ① Professions operational capability of the "double " teacher ; ② experimental ability, with practice, teaching and research experiments and technological innovation capacity ; ③ social practice ability, to understand society , markets and companies to develop students' The ability to guide students to successful employment . 2.2 Teachers should have a sense of innovation and creativity teachers to constantly learn new knowledge , new skills , knowledge and timely adjust their structures to adapt to changing operational needs. Only their own with a strong sense of innovation and innovation capability, summarized from practice innovation, consciously thinking of knowledge and innovation combine to teach students . Meanwhile, the timely detection of students 'creative potential and capture students' creative thinking glittering , multi-level, multi-angle to cultivate their sense of innovation and creativity . 2.3 Teachers should have a strong teaching ability which requires teachers to have a strong ability to express a clear theme in teaching , concise, well organized , interesting to put the knowledge and experience to effectively teach students ; has strong tissue processing ability to select appropriate teaching methods , teaching for students' cognitive development, improve teaching effectiveness . 2.4 Teachers should have the modern means of education in order to meet student needs to study , teachers must be familiar with multimedia technology, a variety of educational software , skilled use of advanced equipment ; thus effectively improve teaching efficiency ; teachers must make full use of network resources, teaching information gathering and enrich and updating teaching content, teaching methods and teaching methods . Meanwhile, the use of information technology for resource sharing of learning, self- discovery and students . Explore , and fully mobilize the initiative of students , enthusiasm, so that the students' innovative thinking and practical ability to effectively exercise. Three scientific use of teaching methods to ensure the quality of teaching 3.1 educate and guide students to promote independent learning achievements in recent years, enrollment of students enrolled is generally low , and the social impact of the environment , resulting in students learning enthusiasm is not high, lack of confidence in learning , learning initiative and consciousness poor academic performance poor, subjective factors by non-intelligence factors, manifested as lazy , scattered and poor . Therefore, the choice of effective teaching methods and educational philosophy as a student -centered , highlighting student learning activities , students focus on the subject as subjective factors that promote students' self-learning ability . In the teaching process based on the guide and inspire , mobilize the enthusiasm for learning , so that students in the learning process change from passive to active , to develop students thinking skills, judgment and ability to innovate. As the saying goes , " teach him to fish, rather teach him to fish ." In particular teaching process, firmly grasp the " nature of a test structure a ( ie, identification, inspection , assay ) ," the main line , combined with medicinal chemistry, analytical chemistry and other related courses knowledge to guide students dissect drugs from staffing structure and analyze the corresponding physicochemical properties, and thus learning methods . Students in imparting knowledge , but also to teach students how to learn this course. 3.2 to student-centered teaching methods to determine 3.2.1 change the traditional way of teaching , strengthen situational teaching : traditional teaching, teachers tend to impart knowledge for the task , the students acquire knowledge for the purpose of places , "Teacher centered" approach, ignoring the situational teaching , ignoring the right students' ability and technical skills training, teaching the theory and practice of light caused by heavy training, a departure from the vocational education and training applications , practical training objectives . Change the traditional classroom , students focus on situational teaching , strengthen the hands-on ability and social adaptation needs . To explain the precision , for example, under different conditions, the precision can be divided into repeatability, intermediate precision and reproducibility can be designed according to different conditions of the three scenarios , teacher voice to explain, let three students to participate in demonstrations. Originally difficult to understand more abstract knowledge through situational teaching students easily mastered . 3.2.2 change the traditional " spoon-fed " teaching , focusing on cooperative learning : the traditional " spoon-fed " teaching, only emphasizes teachers "teaching" , ignoring the students "learning" and the main role of individual differences . This teaching method lead to lack of communication both teachers and students , teaching and learning are mutually disjointed , light weight teach science . Emphasizes theory and practice , students good sense of cooperation , drug analysis is an important trend change teaching methods . Especially in the experimental teaching to allow students to actively participate in class preparation , under the guidance of teachers , some of the students involved in the preparation work, such as reagent weighing, solution preparation and calibration and commissioning and calibration of the instrument , and pre- trial closed . Allow students to participate in the preparatory work before the experiment , help students to actively thinking and problem-solving ability, experience of cooperative learning fun and improve interest in learning , but also improve the teaching quality . 3.2.3 individualized, try layering teaching : students' basic level is low and uneven. Greater disparity prominent personality characteristics . Solve this problem, teachers should change " go hand in hand ," the teaching concept , the implementation of hierarchical teaching . Teachers in the teaching process to fully take into account the degree of difference between the students , for different levels of students impose different requirements , and give different degrees of learning guidance ; different characteristics for different students were to be inspired , guidance and encouragement , prompting students meet the teaching requirements toward direction. Always observe the real-time status of every student , at the most opportune time to give the most appropriate and modest knowledge transfer . In explaining the determination of the calculation , we can inspire students to read the first attempt to complete the three capabilities from simple to difficult goal: to write about familiar topics reaction equation ; correctly identify titration solution and the molar mass of the test substance relationship ; complete the calculation of the measured substances. Thus, different levels of students have the opportunity to reap the success of emotional experience , and can identify gaps , through the efforts to catch up. 3.2.4 The rational use of multimedia technology : Students novelty divergent features more prominent, modern teaching methods popular with students . Teaching the traditional teaching and multimedia technology aided teaching organically combine the best of both advantages, strengthen teacher-student communication , grasp the teaching rhythm , and enhance teaching effectiveness. The abstract concepts and theories to the image , easy to accept in the form presented to the students, to provide students with a comprehensive multi-sensory stimulation to the students a fresh feeling. Through language , sound, illustrations collection, so that each section of the experimental class are vivid , lively and fun to show , stimulate students ' enthusiasm and conscientiousness . For example , teaching salicylates identification when UV absorption spectra and infrared absorption spectrum through the slides to explain , for a particular group characteristic absorption peak is much easier to explain , students are more likely to accept. Determination in explaining the content of suppositories when aspirin alone plus the teacher taught the traditional blackboard is very boring , it is difficult to explain clearly , the students also difficult to understand, if we can accompanied by maps , teachers while playing multimedia, this explanation , you can achieve amazing results. 4 to establish a harmonious relationship between teachers to improve teaching effectiveness Suhomlinski said: " between teachers and students is a mutual friendship and mutual respect and harmonious relationship, which will be conducive to teaching tasks ' , trapped . Harmonious teacher-student relations are an important component of education in vocational schools part of it into a powerful educational force , encouraging students to self-improvement , using a variety of teaching methods for teachers to provide conditions ! 4.1 care for students, teachers and students to promote feelings of every student , whether or underachiever outstanding student , the teacher will have a longing to get the teacher's attention and understanding , eager to share their satisfaction in the hearts of teachers ' roles . " Suhomlinski said: "If you do not love the students , then your education outset means fail ." Thus, the emotional investment is itself an educational force. Teachers should care for each student , fair treatment , not eccentric , especially for poor students , to encourage more giving and caring , good at discovering the advantages of their shiny , believe their potential to effectively help them to mingle with them as much as possible , heart to heart talk with them , to do their " close friends ." Further improve the teacher-student friendship , enhance teacher-student relationship. 4.2 Respect students, promote student interaction on the premise of building a harmonious teacher-student relationship is to respect the personality of students , only you first respect for the students , the students will respect you . Each student is an independent entity, they have their own ideas, have excellent side, there are insufficient side, while the teacher's role is to walk into their hearts , continue to educate and guide them to make their changing thinking , mature, meet students ideological and moral requirements. Only the students devoted affection in order to obtain the trust and respect of the students , the students will be " pro-teacher and believes in its path ." " Three rows, must be my teacher ," good teacher-student interaction is the students to acquire knowledge and skills important safeguard is that students maintain a high interest in learning the importance of motivation. 4.3 Association appreciated the effectiveness of an educator harvest once said: " The whole secret of education , it is to make educated to be confident about the future full of hope ." Teachers give students confidence is appreciated , is to open the door to the golden key to students' potential . To fully appreciate the students must understand the students , whether the advantages or disadvantages to be found in a timely manner , to be guided . The only way to fully extend and develop students' ability to innovate, to enable students to be successful , confident, pleasant emotional experience . Timely , adequate and appropriate for students appreciated, often have a multiplier effect of education and teaching . One operation demonstrates the precise amount required 20mL of the solution, but found that the lower end of the pipette breakage can not be accurately weighed , then between " existing instruments can do it ." One student said : "You can use the burette ." Timely recognition of the students , the students are also casting envious eyes . The student has a great touch , school becomes a serious focus on the original small problems also changed, performance is also a great improvement , which is appreciated by the credit. Overall, teaching is no fixed pattern , drug analysis based on professional characteristics to be good teachers , student situation , social needs, reasonable adjustments and updating teaching content subjects , using flexible teaching methods , in practice, continue to accumulate experience , explore and improve teaching methods to improve the quality of teaching pharmaceutical analysis . |
