Victor Oxman; Moshe Stupel – International Journal of Mathematical Education in Science and Technology, 2024
We present an investigation of the infinite sequences of numbers formed by calculating the pairwise averages of three given numbers. The problem has an interesting geometric interpretation related to the sequence of triangles with equal perimeters which tend to an equilateral triangle. Investigative activities of the problem are carried out in…

Iraya Yánez-Pérez; Radu Bogdan Toma; Jesús Ángel Meneses-Villagrá – Journal of New Approaches in Educational Research, 2024
Virtual laboratories and simulations have emerged as innovative solutions for science teaching. However, existing resources have various limitations and constraints including cognitive load/mental burden and limited coverage of all necessary steps in scientific inquiry, focusing mainly on the experimental simulation. To bridge this gap and address…

Contreras, José N. – Mathematics Teacher: Learning and Teaching PK-12, 2022
Sequences are an important topic--not only in mathematics but also in the mathematics curriculum. Exploring sequences related to medial triangles offers learners opportunities to solve problems involving sequences within geometric contexts. Sequences related to medial triangles are also a rich source of beautiful and interesting geometric patterns…

Shoffner, Melanie – Contemporary Issues in Technology and Teacher Education (CITE Journal), 2009
This article examines the role of technology in preservice teacher reflection. Situated in informal reflection (Shoffner, 2008), preservice English teachers' choice of a specific technology medium for reflective practice is examined for satisfaction with their choice and understanding of that medium's influence on their reflection. The…

Anderson, Susan E.; Maninger, Robert M. – Journal of Educational Computing Research, 2007
This study investigated changes in and factors related to students' technology-related abilities, beliefs, and intentions. Participants were 76 preservice teachers who responded to pre- and post-course surveys while taking an introductory educational technology course. Statistically significant changes were found in students' perceived abilities,…
