Khmer Essay “What made me excited the most as a physics teacher in 2022”
អ្វីដែលរំភើប និង សប្បាយចិត្តបំផុតក្នុងនាមជាគ្រូសម្របសម្រួល បង្រៀនមុខវិជ្ជា រូបវិទ្យា គឺ ការដឹកនាំសិស្សថ្នាក់ទី ១១ និង ១២ ពិសេស ប្រមូលហត្ថលេខា របស់សិស្សមួយសាលា ដើម្បីបញ្ជាក់ថា ពួកគាត់បានមកដល់ CERN (ភាសាបារាំង: Conseil européen pour la recherche nucléaire, ភាសាអង់គ្លេស: European Organization for Nuclear Research) ដែលស្ថិតលើទឹកដី ប្រទេសស្វីសផង និង បារាំងផង។
មុននឹងឈានជើងទៅដល់ទីនោះ វាផ្តើមចេញ ពីចំណូលចិត្ត មើល Scientific Documentary “Particle Fever” រួចដាក់វាបញ្ចូលទៅក្នុងកម្មវិធីសិក្សារូបវិទ្យាថ្នាក់ទី ១២ ( Teacher Diary លេខ 006)។ ខ្ញុំស្រមៃចង់ទៅមើល និង ទស្សនានៅទីនោះផ្ទាល់យកតែមែនទែន ។ គាប់ជួន កម្មវិធីប្រកួតមនុស្សយន្តអន្តរជាតិ FGC 2022 ប្រព្រឹត្តទៅនៅទីក្រុង ហ្សឺណែវ ប្រទេស ស្វីសល្មម ហើយខ្ញុំក៏មានភ័ព្វវាសនា ត្រូវបានជ្រើសតាំងជាគ្រូបង្វឹក ដឹកនាំសិស្សតំណាងប្រទេសកម្ពុជា ទៅប្រកួតនៅទីនោះ ពិសេសទៅទៀតនោះ គឺ … CERN នៅក្នុងទឹកដីហ្សឺណែវទៀត។ Oh …ចៃដន្យម្ល៉េះ … may be God’s Plan ។ Then AIDA model need to implement and make it into reality (visit CERN).
AIDA Model
Attention: I captured my students’ attention by starting introduce them Modern Physics that beyond textbook curriculum. I began by connecting Motion of a Charged Particle in a Magnetic Field to Cyclotron and after that showing them captivating images or videos of cyclotron, the Large Hadron Collider (LHC) at CERN, emphasizing its size, complexity, and importance in scientific discoveries.
Interest: Once I had their attention, I generated interest by highlighting the fascinating physics concepts studied at CERN. I showed the a document named “Particle Fever”, talked about particle physics, the search for fundamental particles, and the mysteries of the universe that scientists at CERN were trying to unravel. I discussed topics like the Higgs boson, dark matter, and antimatter, explaining how they related to our understanding of the universe.
Desire: I created a desire among my students to visit CERN by showcasing the unique learning opportunities it offered. I explained that a visit to CERN provided a chance to witness groundbreaking experiments, see cutting-edge technologies in action, and interact with leading physicists and researchers. I emphasized that this experience could deepen their understanding of physics and inspire them to pursue careers in science and research.
For example, I and FGC – 2022 team convinced my director to extend our visit to Geneva to include a trip to CERN and requested a budget for it. Not only did my efforts succeed, but the entire school also signed a signature on a big poster to represent our school when we arrive at CERN. The experience left a lasting impact on the students, inspiring their passion for scientific exploration and future careers in STEM fields.
Action: Finally, I guided my students on how to take action to make a visit to CERN possible. I provided them with information about the necessary steps, such as organizing a group trip, seeking permission from the school administration, and exploring potential funding options. I offered resources and assistance in planning the logistics of the trip, and we successfully visited CERN on 17th October 2022. The experience was both educational, inspiring, and a life-changing experience.
We were able to visit Synchrocyclotron particle accelerator.
Students’ Reflection after visited CERN

“At first, when I heard about CERN I thought it was ridiculous. Why would people investing millions of dollars just to create a colliding particle machine. After visiting CERN, I know that human curiosity is the real deal. To uncover the mystery of this vast universe, they started from a small machine to this big collider in the present time that we know. Another interesting thing is curiosity really bring people far ahead from a different continent to Europe, a real encountered is that my guide at CERN was from Pakistan. However, I have two thoughts in my mind when I listened to the guide:
1. I wish I learned this in school so I understand what he’s talking about.
2. I wish more people know about this. Since the guide mentioned that this is the first time he has met Cambodian tourists and there’re a lot of interesting things that they are discovering.
The thing I have learned there is also physics but if no one told me and I haven’t been there I might still think atom is the smallest thing that science has discovered.”

I noticed two types of reaction from people around me when we were talking about CERN. You got the “Huh?” type of people and the “Yeah!” type of people. To be honest, I’m not someone who spent most of my time exploring “Quantum Physics”, but surprisingly I was amazed to be able to understand literally almost everything the CERN guide is talking about. I have been watching random modern physics related content for fun for quite a few years now but never really thought of it more than just EDUTAINMENT and for quite some time now always thought that everyone does so too. Later on, after having the chance to visit CERN. I realized “nah maybe not everyone”, as more than three quarters of the people I talked to are more of a “Huh?” than a “Yeah!” type of person. Quite shocking, yeah! I looked through my physics course book later and found that damn we are so អត់ទាន់សម័យ. We are still taught that “Atoms are the smallest thing” when we now know “elementary particles” like quark, neutrino, higg,… We should really do something about this. I want to see more “Yeahh!” than “Huh?”. It’s 2022 not 1822!
