On the 5th of May, the LATACME seminar series welcomed Nigel Calder, Associate Professor at the University of Waikato in New Zealand. With a range of attendees across HVL, we enjoyed listening to Nigel’s presentation about “Help or Hindrance? How do mobile technologies influence teaching and learning, with mathematics in particular.” He shared with us his ideas, not only about what affordances can mobile technologies have in terms of the ways they might influence learning, but also about what can get lost if they are misused or become a panacea that replaces other pedagogical forms of teaching and learning. In the examples of digital apps that he showed us, we found many relevant themes to our project, such as modelling in real-life situations, programming with Scratch, critical thinking and the role of language when students become the leaders of learning. These ideas are very useful for us to bring into a discussion with the pre-service teachers in our program. It was an exciting day and we enjoyed learning about other collaborations that take place in the other side of the world. We thank Nigel for joining us at this breakfast Zoom-seminar and sharing his work with us. Keep smiling!
