Newly built replicas of relic sites and landscapes at the Trần Mai Ninh Secondary School are making history and geography classes more vivid for junior students in the central province of Thanh Hoá.

 Autumn sunlight is spread out over the replica complex in the schoolyard inspiring students to learn a new subject — location education. 

Some of the 15 replicas such as the Hồ Dynasty Citadel, the Hàm Rồng Bridge, Ba Đình Square and others are set in a 2,000 square metre yard in the school. The complex was completed two months ago to meet the demands of teaching the new subject for the 2021-22 school year.

 The complex was built during the summer vacation with a view to serving Grade 6 students under the Ministry of Training and Education’s instruction and the provincial Department of Training and Education’s curriculum, according to Trần Thị Phương Lan, principal of  the school. 

“The replicas aim to help students see historic relic sites and landscapes of the province at the school who have not had a chance of going to the real sites due to the COVID-19 pandemic,” Lan said. 

“It also makes teaching and learning more effective and noteworthy, inspiring students in patriotism and national pride. The students will be aware of the tradition of preservation and development. Field trips cannot be held due to the pandemic, so the replicas are really helpful for teaching and learning.”

The highlights of the site are the replica of Ba Đình Square and the statue of President Hồ Chí Minh reading the Declaration of Independence to establish the Democratic Republic of Việt Nam in 1945.

It is a nice surprise for students who mostly have not had a chance to visit Ba Đình Square in Hà Nội. They possibly do not know that the square was named after the historic Ba Đình Uprising in Nga Sơn District in Thanh Hoá Province in the 19th century. 

Each replica in the complex is accompanied by an information board.

Near the gate of the school is the replica of the relic of the citadel of the Hồ Dynasty (1400-1407), which was recognised as a World Culture Heritage site by UNESCO in 2011. 

The citadel, mentioned in Đại Việt Sử Ký Toàn Thư (The Complete Annals of the Great Việt), was built during the reign of King Trần Thuận Tông (1388-98) by Prime Minister Hồ Quý Ly, who acceded to the throne in 1400.

It is the only fortified citadel with unique stone architecture remaining in Southeast Asia. 

Another replica, Ngõ Nhân (Nhân Lane), was selected among five lanes, namely Nhân, Nghĩa, Trí, Lễ and Dũng, representing the five constant virtues of kindness, uprightness, wisdom, decorum and braveness, in a Đông Sơn ancient village to be placed at the site.

It is the only original lane gate remaining in the village, according to the principal. 

A replica of a Đông Sơn bronze drum is placed together with Ngõ Nhân to let the students know more about Đông Sơn culture. Đông Sơn District was the first place to unearth ancient Đông Sơn bronze drums dating back to more than 2,000 years ago. 

Selecting the historical sites and landscapes symbolising the province development was discussed by the teachers, according to Lan. 

“We want the students to have a comprehensive view not only of history and culture but also society and economy,” she said. 

This explains why the complex also comprises of the Nghi Sơn Economic Zone, Sầm Sơn Beach and Pù Luông Natural Reserve. 

“The complex is beautiful and useful for us,” said Trương Gia Bảo, a pupil from Class 6H. “It encourages me to learn about the popular historical relic and geographic sites in Thanh Hóa Province.”

Trần Hữu Phước from Class 6B also expressed his interest in the site. 

“This is a wonderful model helping us know more about the historical sites and landscapes of my homeland in an effective way,” he said. 

According to Lê Hà Nhật Lâm, from Class 6A, the complex inspires her and her classmates to learn the new subject in their first year of secondary school. 

“It is amazing to see the vivid replicas at the school,” Lâm said.

“We do not have to sit boringly in the class reading books and watching a projector. We can go to the complex to see the replicas which help us learn about culture, history, geography, society and the economic development of our province.”

The complex was completed at the end of August, aimed at welcoming in the new school year. In a short time, it has been effective for both teaching and learning, according to literature teacher Nguyễn Thị Loan. 

“The students who are lacking knowledge of local history will get to know milestones of the provincial history,” Loan said.

“They will be active to learn and be more proud of their homeland and other cultural values of the nation. I assigned the students a task to research and collect information about the relic sites to summarise both in Vietnamese and English. These presentations will also boost the English learning and presentation skills of the students.”

A large mural on the wall opposite the site gives historic development and geographic milestones helping not only students but school visitors understand the project.

The site construction won the second prize at the provincial 2021 Science and Technology Innovation Awards. It is one of the nominations for the National Awards, which will announce the winners in December. VNS

Scientist brings solar energy closer to people



When beginning his journey to the US at the age of 20, Nguyễn Trọng Hiếu showed an endless passion for science. From a young student, Hiếu has become one of the nation’s leading scientists in engineering. With pioneer initiatives in solar energy, he and his team have taken humanity one step closer to a future where solar energy can thrive. Việt Nam News reporter Hoàng Hồ talks with Hiếu about his journey.

With excellent scientific research works, Nguyễn Trọng Hiếu was honoured to be nominated by the Central Committee of the Hồ Chí Minh Communist Youth Union in the list of 20 outstanding young Vietnamese in 2021. Photo courtesy of ANU

Inner Sanctum: How did you feel when your name was announced among 20 outstanding young Vietnamese in February? What were the turning points in your career?

I’m thrilled and proud to be honoured as one of the outstanding young faces of Việt Nam as a rep for the scientific research category. This motivates me to continue what I have been doing — performing good research and supervising and teaching my students, and mentoring junior colleagues.

I won a full scholarship to study at the Portland State University, USA, thanks to my performance in the first two years of studies at the Hồ Chí Minh City University of Technology. It was a huge step for me. But the turning point was when I started my PhD at the ANU College of Engineering and Computer Science, Australia, immersing myself in their world-class solar device fabrication and characterisation facilities. I received excellent mentoring from many world-renowned researchers and collaborated with many world-leading research groups.

Inner Sanctum: What are the challenges in reaching sustainable solar energy? 

The Earth receives thousands of times more solar energy from the Sun annually than the world’s total energy consumption. However, solar energy usage is still limited due to its higher cost than conventional electricity sources.

This is primarily because of the commercial solar cell efficiency (20 per cent), which is still far below the theoretical limit. The current challenge in improving solar cell efficiencies is the poor understanding of factors that can potentially cause efficiency losses at various stages. My work is well on the way to addressing this knowledge gap and providing the community with new tools to characterise these losses and novel processes to minimise them.

Inner Sanctum: Can you explain your research, its goals and the specific applicability of the research in daily life?

Dramatic climate change forces humanity to seek clean energy sources that are efficient, cost-effective, and reliable. Solar energy is an obvious solution. My research goal is to make solar energy cheaper and closer to everyone. I’m doing it innovatively – exploring light emitted from solar materials.

Nature gives physical things beautiful colours, which are a key to unlocking the potential of solar technologies. The secret is that every part of light emitted from materials contains important information. Examining the emitted light allows me to determine the most efficient material to use.

Because emitted light has unique features corresponding well to certain material properties, I can diagnose the material characteristics by just ‘looking at’ but not ‘touching’ them. I am taking it a step further – after understanding the material properties, I apply the knowledge to the fabrication process.

Much of my research directly supports R&D engineers to improve the efficiency of solar cells. These innovations could be applied to make better solar cells by different solar cell and module manufacturers. Then, the devices will be distributed around the globe, including in Việt Nam.

This will help the industry make more efficient and cheaper solar cells, unlocking the full potential of solar energy and providing low-cost renewable energy for humanity.

Inner Sanctum: Can you share your passion for a field that is difficult for many people? Did you have any difficulties at the beginning of your journey in the US? 

My love for physical science took me to engineering. Then, my bachelor’s study was in electrical engineering, grounded in semiconductors. Ten years ago, solar cells were a hot topic, a path to tackle our climate change. The bulk part of solar cells is semiconductors. I decided to follow this area to utilise my background and do something meaningful for the world.

The greatest difficulty at that time was my English, particularly my writing and speaking skills. To overcome them, I just practised and practised. Practice makes perfect.

Inner Sanctum: How is your time working abroad? What in the US and Australia can Việt Nam learn from?

So far, I have enjoyed my time working in the US and Australia very much. I have built collaborations with numerous leading research groups around the world. These collaborations have provided me with unique opportunities to learn a wide range of state-of-the-art solar cell fabrication processes and characterisation techniques.

I am happy with their open working culture. I’m free to express my opinions and ideas even though they sometimes contradict the majority. VNS
