Hannele M. Niemi urges more investment in teacher preparation as AI reshapes classrooms

Education researcher Hannele M. Niemi is pressing for stronger teacher preparation, better classroom conditions and AI-ready learning as schools face teacher shortages and widening achievement challenges. Her argument comes as UNESCO says the world needs 50 million more teachers by 2030 to meet universal education goals.

Why it matters: - Teacher shortages, uneven student achievement and fast-moving AI tools are putting new pressure on education systems worldwide. - Niemi argues that better-prepared teachers are central to quality, equity and student learning. - The debate affects how countries recruit, train and support educators at a time when demand is rising.

What happened: - Hannele M. Niemi, an education researcher and author of The Teacher’s Role in the Changing Globalizing World: Resources and Challenges Related to the Professional Work of Teaching, called for greater investment in teacher preparation and the professional conditions teachers need to succeed. - Niemi said education quality depends on how well teachers are prepared to teach, not just on adding more teachers. - The comments were released in Los Angeles on October 12, 2026.

The details: - UNESCO data released on World Teachers' Day 2026 says the world has 107 million teachers but needs 50 million more by 2030 to provide universal access to pre-primary, primary and secondary education. - Niemi said quality teaching depends on what a teacher can do in a specific context with specific learners and within the conditions of the education system. - The OECD’s Program for International Student Assessment, or PISA, measures how 15-year-old students apply reading, mathematics and science skills. - Niemi said artificial intelligence can support learning, but it must not replace critical thinking, knowledge and understanding. - Niemi said students need guidance to use AI responsibly, judge the accuracy of outputs and understand limits. - Niemi said teachers also help students ask questions, evaluate evidence, solve problems and make informed decisions. - Niemi said classroom environments should let students feel respected, ask questions without fear and learn through investigation and practice. - Niemi said teachers need strong preparation, ongoing development, adequate resources and autonomy to adapt to different learners and changing circumstances.

Between the lines: - The message is broader than a staffing warning. Niemi is making a case that education policy should focus on the conditions that let teachers do high-skill work. - The comments also position AI as a reason to strengthen teaching expertise, not reduce it. - The emphasis on PISA and UNESCO data suggests a global policy argument, not a local classroom fix.

What's next: - Countries facing teacher shortages are likely to face more pressure to invest in training, professional development and working conditions. - Schools and systems will also need clearer rules for how AI fits into teaching and learning. - Niemi says investment in teachers should remain central as governments respond to international assessment results and technology-driven change.

The bottom line: - Niemi’s core message is simple: education systems cannot solve learning gaps, shortages or AI disruption without better-prepared teachers. - More recruitment alone will not fix the problem unless teachers also get the support, autonomy and training to teach well.
