In order to assist the teachers in each region to learn the excellent teaching experience and improve their scientific thinking and practical teaching ability, on the afternoon of May 6, 2021, before the meeting of headmasters of partner schools with a theme of “Promoting Moral Education through Socio-scientific Issue Learning”, a delegation of over 40 members including regional heads of SSI-L project, headmasters and backbone teachers of partner schools paid a visit to the laboratory of the Second High School Affiliated to Beijing Normal University. The delegation was received by Peng Menghua, the head of subject guidance expert panel of the project group and a special-ranked physics teacher.
Secretary Shen Jinghong, the leader of the Second Affiliated High School delivered a welcome speech to the delegation of partner schools for their visit and exchange on the experimental teaching of the school. They first visited the biological laboratory and musical instrument production laboratory on the second floor of the laboratory building, and then visited the three physics laboratories on the fourth floor. In his teaching career of over 40 years, the teacher Peng has made thousands of physics teaching aids. The devices and inventions displayed in the three laboratories were just some of his works, ranging from high voltage discharge device to the luminous dial used to demonstrate the animation principle, all of which reflected his education wisdom and practical ability. During the visit, two teachers Peng and Han demonstrated the uses of teaching aids and explained their physical principles and highlighted the great value of teaching aids to the students’ physics learning. Peng said, the learning of science depends on careful experiments and practices rather than homework and exercises.
The school is one of the partner schools of SSI-L project. In the learning of the topic “Can electroacoustic musical instruments replace traditional ones?” in this semester, the students learned to produce electroacoustic musical instruments under the guidance of the teachers Peng and Han. During their visit, the teacher Peng showed the musical instruments such as electric guitar and erhu made by himself, explained the working principle and production steps of electroacoustic musical instruments and played a piece of music “Horse Racing” at the site. Peng said, the students could experience the difficulty of putting the principles into practice in the production of musical instruments. In constant attempts, they gradually discovered the sound production law of musical instruments and kept improving their works. He believed that the students would understand the principles more deeply through practice. Peng also made a piece of erhu especially and gave it to Sandun Middle School as a gift.
The two-hour visit was so short. The headmasters and teachers of partner schools were all surprised by a large number of delicate and ingenuous teaching aids made by the teacher Peng, and expressed their admiration from the bottom of heart. They all agreed that if it would have been their great fortune if they could learn with the teacher Peng during their senior high school years.
In the visit, the diverse teaching aids and wonderful explanation of the teacher Peng showed his deep enthusiasm and understanding of physics teaching. The visit has offered great help for the teachers to expand their teaching thought and improve their teaching skills and further facilitated the smooth facilitation of SSI-L project in each partner school.
