Mathematical and Coding Lessons Based on Creative Origami Activities
2019
AbstractThis paper considers how creativity and creative activities can be encouraged in regular mathematical classes by combining different teaching approaches and academic disciplines. We combined origami and paper folding with fractals and their mathematical properties as well as with coding in Scratch in order to facilitate learning mathematics and computer science. We conducted a case study experiment in a Serbian school with 15 high school students and applied different strategies for learning profound mathematical and coding concepts such as fractals dimension and recursion. The goal of the study was to employ creative activities and examine students’ activities during this process i…
Developing Primary School Students’ Formal Geometric Definitions Knowledge by Connecting Origami and Technology
2019
In this paper, we present opportunities with the uses of origami and technology, in our case GeoGebra, in teaching formal geometric definitions for fifth-grade primary school students (11-12yrs). Applying origami in mathematical lessons is becoming to be recognized as a valuable tool for improving students’ mathematical knowledge. In previous studies, we developed origami and technology activities for high-school mathematics, but we wanted to explore if such approach would work in primary school as well. For this reason, we chose a flat origami model оf the crane and we used this model to introduce students to basic geometrical notions and definitions, such as points, lines, intersections o…
Ideas for using GeoGebra and Origami in Teaching Regular Polyhedrons Lessons
2018
The approach of combining GeoGebra and origami is well accepted among students in the school "Petro Kuzmjak" where it is used to teach geometry lessons. This article elaborates on how to introduce students (upper elementary and high school students, age 14-18) to Platonic solids and their properties through combination of GeoGebra and origami activities. Some of the important mathematical concepts related to these well-known geometrical solids can be explained to students applying hands-on activities along with educational software. peerReviewed
Conductivity measurements of DNA TX tile and origami structures
2011
Tässä tutkielmassa on tutkittu kahden erilaisen itsejärjestyvän DNA-rakenteen sähkönjohtavuutta nanomittakaavassa. Ensimmäinen rakenteista on suorakaiteenmuotoinen kaksiulotteinen DNA-levy kooltaan noin 70×100 nm2 toisen ollessa selvästi kapeampi, noin 10×60 nm2. Suurin ero rakenteiden välillä on valmistusmenetelmä: isompi rakenne on valmistettu origamitekniikalla ja pienempi niin sanottua tiilimenetelmää käyttäen. Molekyylielektroniikan kannalta DNA:n sähkönjohtavuus on oleellinen asia, sillä DNA on itsejärjestäytymisominaisuuksiensa vuoksi osoittautunut hyvin lupaavaksi molekyyliksi: yksinkertaisten nanoskaalan laitteiden valmistus käyttäen DNA-pohjaisia menetelmiä on jo mahdollista. Työs…
