With the introduction of AI and Edtech tools, older teachers are losing confidence. The birth rate in OECD countries has been declining recently, with the average being 1.59, which is less than the population replacement level of 2.1. On the contrary, the elderly population is increasing, accounting for 17.1 percent of all OECD countries last year. The number of elderly teachers is also increasing. The Office of Education is encouraging teachers to participate in digital literacy education to improve instruction and innovate in the classroom through the use of various edtech and AI. However, older teachers I’ve met are not good at keeping up with educational content, and their confidence is declining. After all, they go back to the traditional way of teaching. (Some are even considering early retirement.) This makes it seems like they are in a negative position on using Edtech tools. We have also recognized them as complacent teachers in the past way. Why do they stick to traditional teaching methods even though they are constantly learning? Choosing the right app from among a variety of digital tools and using them is also a difficult task for young teachers. In class, older teachers are hesitant to make new attempts due to mistakes caused by using the Edtech tool and fear of not being able to use it perfectly. This suggests that we need to go beyond simply providing basic education and consider their atrophied psychology and diminished sensory capabilities. They are not opposing the introduction of Edtech tools. Rather, they are just teachers who are maladapt to the use of edtech and have lost confidence. One day, we may be in their position. How might we increase older teachers' confidence and proficiency in integrating Edtech into their teaching methods?
