"Do not forget your initiative mind, keep in mind the mission. The youthful passion of the first heart, how not to be old? The research and development and application of science and technology is one of the tricks. The use of advanced digital experimental instruments to build an experimental environment, with better and faster experimental means, with 'digital' to visualize 'phenomenon', is a good example." This is what he has personally experienced in the continuous attempt of experimental teaching. He is Zhang Xiangping, a senior teacher who has worked on the front line of teaching for nearly 40 years. He became acquainted with SWR Company in 2014 and has been thinking about the improvement of experimental teaching. In November this year, he participated in the training of scientific inquiry experimental skills in jurong city Primary School. During the in-depth technical exchange with SWR. He always keeps his mission in mind and adheres to the road of professional development. Coinciding with December 13 this year, Jurong City is about to hold the first digital experimental teaching skills competition for primary and secondary schools. Teacher Zhang Xiangping started the preparatory work early and has already conducted an open class trial in the third and fourth grades of the school. Among them, SWR provided both instrument and technical support for Mr. Zhang's open class.
01 How to control experimental variables? Teacher Zhang will teach you hand in hand!
In the conventional experimental teaching of "the law of movement of the pendulum", teacher Zhang instructed the students to do many experiments, but it was difficult for the students to grasp the experimental variables, such as time, pendulum time, pendulum angle, and the construction of the experimental environment. There are differences among individual students, even for the same experimental phenomenon, the same student performs differently in different times of operation. With so much uncertainty, the experimental results are inconsistent, so it is difficult to convince students of the experimental conclusions. Respect the data, but the conclusion of the experiment is not well expressed. What should I do?
Mr. Zhang chose the motion law experiment device, photoelectric door sensor, intelligent digital experiment plate and software of Suweir single pendulum. This experiment device completely solved the problems encountered in the above experiments.
"The design of the experimental device is exquisite, the position of the center of gravity of the pendulum is unchanged, the length of the pendulum can be adjusted freely, which is convenient for students to operate; Without changing the center of gravity and length of the pendulum, the mass of the pendulum can be easily changed, and the experimental data are accurate and reliable. The protractor is designed to facilitate angle measurement and unify variables." Teacher Zhang said excitedly, "The experimental variables are controllable and will not become re-variables due to errors generated by manual operations, and will not change constantly due to changes in the number of experiments! It is intuitive to present the data in tables, coordinate curves and column charts through digital experimental software!"
In class, primary school students are very interested in digital experimental instruments, with bright eyes, straight hands, eager to try. They are either lively, quiet, surprised, or unsuccessful, and then successful, all showing the students' strong interest.
As for the experimental operation process, they will learn it as soon as they learn it, get started quickly, and cooperate with each other in the group. In the process, they are small teachers and are very focused. After making the experimental results, dissatisfaction or errors caused by improper operation can cause students to think and stimulate their desire to seek results, thus further exploring the causes of experimental deviations. For example, what are the causes of data errors? In the classroom practice, students found the answer. It turns out that data errors are caused by pushing pendulum and rotating pendulum, which are not "natural pendulum.
02 SWR Digital Experimental Instrument Has Received Much Attention, Principal Chen of Border Town Central Primary School gave a very high evaluation
At 10: 00 a.m. on December 4, teacher Zhang also showed principal Chen Yiye of border town central primary school in jurong city and teachers of the comprehensive group the professional growth under the background of Suwell's digital experimental environment.
Teacher Zhang used the study and teaching of the digital experiment of "Using" Numbers "to Visualize" Phenomena ", and talked about" Do not forget your initiative mind, Life on the Road of Professional Development ". The aim is to highlight "Do not forget your initiative mind, lifelong learning" and "let high technology help teachers' professional growth", and finally realize "let high technology appear in ordinary classrooms and let children perceive the infinite charm of high-tech means from an early age"!
After the show, President Chen and the teachers of the comprehensive group gave a very high evaluation. They fully affirmed the status and significance of digital experiments in improving teaching quality and guiding students to operate in experimental teaching, and pointed out the future trend of digital laboratories.
Through several open classes this week, Mr. Zhang Xiangping has gained a lot. He has not only been guided and affirmed by the principal and the teachers of the comprehensive group, but also personally experienced the role of SWR digital experimental instruments in teaching. He said bluntly: "Digital experiment innovation is the use of multimedia teaching equipment, the use of advanced digital experimental instruments to build an experimental environment, with better and faster experimental methods, more accurate and more intuitive interpretation of experimental phenomena. Use teaching materials to develop software, use software to develop teaching materials, innovate software, solve home-style classrooms, and help teachers and students develop; digital software and hardware correspond one by one and are indispensable. SWR digital experimental instrument can help the burning of passion and help the beginning to remain unchanged!" Digital experiment is the trend of experimental teaching in the future. In the future, SWR will make more efforts to develop digital experimental instruments to better serve the cause of education.
