“I’m a good example of how having a great teacher can decide one’s future.” – Lidija Kralj, Croatia

“I knew I would be a math teacher at the age of ten,” says Lidija Kralj. “We had a caring, enthusiastic and laughing math teacher who inspired me and sparked in me a love for its logical, methodical approach. It became part of me.”

Kralj says her educational path from that point on was decided: she would study mathematics. “When I started teaching, I was surprised how much I liked working with students, and after being in class for 25 years, I still have that passion,” says Kralj. “I’m a good example of how having a great teacher can decide one’s future.”

Indeed, Kralj’s passion for math shines through daily for her students, and she has developed her own method for teaching: The “270 teaching method.” Kralj gives her students the opportunity to make educational content on a given topic from their curriculum.

“With this method, I give the students some control over what they learn and how they will show what they have learned, by encouraging them to be independent and responsible for the results of their work,” she says. “I also give them real examples of how computers, the Internet and mobile devices can be used to create content and develop their organizational and presentation skills.”

With the 270 teaching method, all work has to be presented in class, and presenters have to involve the whole class. An important aspect is that students’ works are published online so other students can learn and use the projects as educational resources. “So students are teaching students,” notes Kralj.

Kralj is happy to share her stories with other educators and is prolific on her own blog, through Hot Topics (recently sharing her experience using Yammer), and Twitter.

What was a defining moment in your career when you felt proudest to be an educator?

Working on international projects was, and still is, a novelty in our educational system. I started working on such projects eight years ago with a great team of female students. Since there wasn’t anything similar in our neighborhood, we were always a bit exotic in our teaching and learning practice. When after six years one of the girls came back to school to thank me for involving her in these international projects because that led her to getting a scholarship to study outside of Croatia, that made me very emotional and happy.

Why do you feel passionate about innovation and technology in the classroom?

Let’s do more than flip: I use “The 270 teaching method.” Parts of my students’ works are:

  • Videos they recorded themselves, which explain some task or concept
  • Quizzes they create with questions related to the topic of their work
  • Examples and tasks that are not copied from a textbook
  • Images they create in math software, such as GeoGebra
  • Additional content from other authors

Recently I shared my “270 teaching method” with colleagues and they were surprised at this approach to math teaching and with the quality of students’ work. I shared that success with my students and they asked if I could teach more teachers to work this way so they would have the possibility to do similar work when in high school.

I am proud of their and my work. Here are some examples of students work in English:

And some results from previous years, in Croatian:

What’s the biggest obstacle you or your country or region has had to overcome, or will have to overcome, to ensure a quality education for students?

The educational system is resistant to changes and influenced by daily politics which do not recognize teachers’ role and undermine teachers’ position in society. This makes our jobs harder every day.

In terms of education innovation, what are you most excited about for the future? What is your biggest hope for today’s students?

To see my students become creators, not only consumers.

    Thanks for the great teaching ideas. I’d like to try this with elementary science. Our school’s technology is still rather limited, but I think that we can work around that. On another note, it looks like lack of respect for the teaching profession exists in Countries other than the United States too.
