Conceptual images and learning obstacles in exponentiation and logarithms: A hermeneutic phenomenological analysis by Yuvita Andriani Kusumadewi, Riki Andriatna

“…The concept of exponentials and logarithms is one of the essential concepts in mathematics as part of transcendent functions. However, students' understanding of these two concepts has yet to be fully mastered, so there are still errors in solving problems related to these two concepts. …”

Maths on display po polsku, czyli matematyczne prezentacje na lekcjach w klasie III by Katarzyna Wojcieszek

“…Creating conditions for construction of extensive personal knowledge and mental acquaintance with the public knowledge should be the primary aim of teaching mathematics. To assist pupils in their comprehension of mathematics means to give a chance of independent choice of strategies of actions, of implementing into the educational process a number of diversified cognitive processes, in accordance to assumptions of cognitive psychology's findings. …”

A Theoretical Framework for Interrogating the Integration of Artificial Intelligence in Education by Tarisayi Kudzayi Savious

“…The paper argues that the eventual response of educators to recent developments in artificial intelligence is eerily like the earlier cycles of integrating ICT in education and, decades earlier, calculators into mathematics instruction. Premised on the argument that there are similarities between the calculator revolution in mathematics education and the ICT revolution in education several decades ago and the current ongoing developments in artificial intelligence, this paper offers a theoretical lens. …”
