Dr. Jiang Yi made a speech

Subsequently, the College of Life Sciences of Yunnan University and Vice Dean Zhaorong expressed their full support for the event on behalf of the College.After introducing the cooperation with ABE project, I have been thinking about how to effectively connect secondary education with university education.Many useful attempts have been made, such as starting experimental courses in summer with the Talent Program.It aims to strengthen communication between secondary schools and universities. He also said that he was adhering to the concept of providing support services for education in Yunnan.The Academy of Biological Sciences of Yunnan University is willing to support the help needed in biology teaching in middle schools.

He Zhaorong, Vice President, made a speech.

Professor Zhang Guiyou, an invited representative of the ABE project and former director of the Modern Life Science Experimental Teaching Center of Tsinghua University, said that.As an exploration of building a bridge between universities and middle schools, ABE project has been carried out smoothly and successfully in Yunnan.This is due to the strong support of all people.Everyone has the same understanding of the responsibilities and training objectives of universities and secondary schools, and hopes to strengthen communication and exchanges in the future.Bring the experimental experience back to the classroom and sow the seeds of biology in the hearts of students.To contribute to the cultivation of outstanding scientific and technological innovative talents for the country.

Teacher Zhang Guiyou made a speech

Wang Ou, Deputy Secretary of the General Party Branch of Chenggong School attached to Yunnan Normal University and senior middle school teacher, hopes that teachers and universities will maintain exchanges.At the same time, some useful suggestions are given on the difficulties of carrying out experiments in the classroom.Mr. Wang said that he believed that the teachers would pass on the content of the experimental experience to the students, not only the students of this year.Generations of students have ignited their enthusiasm for learning biology and devoted themselves to the cause of building the country.

Finally, Professor, School of Ecology and Environment, Yunnan University,Professor Xiao Heng, Vice Chairman of the Teaching Steering Committee for Bioscience Majors in Colleges and Universities of the Ministry of Education, made a speech.He said that the ABE program's training of teachers can benefit more middle school students, and this activity is important and meaningful.It is hoped that teachers will apply what they have seen and learned in the activities to teaching and improve their professional growth.Consolidate the foundation of talent training in the field of life science in the future.

Teacher Xiao Heng made a speech

The experimental experience was led by Li Yaoxi, the backbone teacher of the Modern Life Science Experimental Teaching Center of Tsinghua University, and Mr. You Fujin, the teaching team.The ABE teaching team Peng Wen and Han Yujie assisted in teaching. The experimental experience is mainly divided into three parts:

In the first part, Professor Li Yaoxi reviewed the specific process of genetic engineering.It deepens teachers' understanding of the operation steps of genetic engineering.Then, Mr. Li explained how to extract plasmids from bacteria and how to cut them with restriction enzymes.And the matters needing attention in plasmid extraction were explained in detail from both positive and negative aspects.Finally, the instructors completed the extraction and purification of plasmids, and used two restriction enzymes to complete the cleavage of plasmids.

The picture shows the two teachers, Li Yaoxi on the left and You Fujin on the right.

In the second part, Mr. You explained the relevant theoretical knowledge and experimental operation steps of electrophoresis technology, recovery and detection of target fragments.。 Teacher You is very careful to combine the content of this training with the basic operation process of genetic engineering in PEP high school biology textbook optional compulsory 3.It is convenient for teachers to bring the theory and operation of this training into their daily teaching.

When experiencing the recovery and detection of objective fragments, teachers can operate the sample and feel the electrophoresis experiment intuitively.During the waiting process of the experiment, Mr. You shared with the students the types and characteristics of expression vectors and the application of fluorescent proteins.Interesting subject knowledge guides teachers to stimulate students'interest in learning with novel scientific knowledge.

In the third part, Mr. Li Yaoxi explained the principle of PCR and led the teachers to practice.The PCR products were detected by agarose gel electrophoresis at the molecular level.

In the course of teaching, interactive communication links are interspersed to solve the teaching problems of teachers.For example, why to choose HindIII and Bamhi restriction enzymes, the principle of agarose gel electrophoresis and how to choose the appropriate restriction enzymes.Etc. The combination of theory and practice makes the classroom experimental teaching no longer rigid and effectively improves the teaching efficiency.

In addition to the experimental experience, Professor Zhang Jie and Associate Researcher Wang Houping of the College of Life Sciences of Yunnan University also brought special courses.

Teacher Zhang Jie takes "We behind the exploration of the law of life-model organisms" as the theme.What are model organisms, the characteristics and selection of model organisms, common model organisms, and the research strategies of model organisms.The importance of introducing model organisms. Students can study cell biology, biochemistry and genetics in the context of existing disciplines.Combining with the landmark original research and technological inventions in biology, the selection process and application mode of model organisms are analyzed in depth.To construct the logic and overall view of biological research, to build a bridge between knowledge and practice for future laboratory research.
