Erasmus+ PUSE (Poly-Universe in School Education) project www.poly-universe.comThe Poly-Universe geometric skill development tool was invented by visual artist SAXON. The novelty of the game lies in the scale shift symmetry of the basic shapes, and in the colour combination system attached to it. Although the tool consists of truly simple elements and attributes (basic shapes, basic colours, proportions), it is at the same time also extremely complex, because by shifting proportions and changing colour combinations and their relationships, the number of possible solutions becomes virtually endless. That is why the Poly-Universe is more than play, more than art, more than maths, it includes all: synergy in education… The Erasmus+ PUSE project was the main step taken to map how Poly-Universe's artistic-scientific approach could enter the gates of mathematics education. Its necessity was proven by workshops held in dozens of countries, by the participation in math-art conferences and also by the research project of the Hungarian Academy of Sciences in 2015. The goal of the project was to develop a geometric-combinatorial educational method, primarily for mathematics education, based on a visual system. The outcome of the project is an educational methodology book and students' worksheets (EN, HU).PUSE METHODOLOGYVisual Experience Based Mathematics Education 2019ISBN 978-615-81267-0-0The original goal of the size of the methodology book was between 100-200 pages. Finally the printed PUSE teacher book & PUSE exercise book was put together to make the PUSE Methodology Book on 600 coloured pages with 500 graphic illustrations. The student worksheets target three different age groups: primary school early years, upper years, and high school students. The methodological part is divided into five chapters. Each chapter is made up of methodology sheets meant for teachers, paired with student worksheets:1 Geometry & Measurement2 Combinatorics & Probability3 Sets & Logic4 Graphs & Algorithms5 ComplexThe final output of our educational methodology is an interactive PUSE online system, where we can use the advantages of ICT based teaching, and how we can maintain it for a long time, however this is an interactive platform, with an expandable online source of exercises. The main goal was to develop an PUSE interactive surface for teachers, who use the methodology in their classes. Therefore to use the program with internet we published the online PUSE Teacher’s book and Exercise tasks (EN-HU). In the future, when the methodology book is translated into several languages in EU education systems we would like to constantly expand the editions...The PUSE Methodology was created by a group consisting of teachers, students, artists, an inventor, psychologists, a sociologist and external experts. The four partner school organizations (Finnish, Hungarian, Slovak, Spanish) come from different regions of Europe and operate in different educational systems. Thanks to the international partnership, we learned how students and teachers approach the passages between arts and maths, problem solving based on Poly-Universe's visual system in a Scandinavian-type educational system; in a Western-European environment based on the PISA method; in a strongly mathematically centred Central-European educational system and in the specific circumstances of minority schools. All participating schools gave valuable contributions to the development of the methodology and the exercises. Going beyond educational aspects, the need arose to map connections between the tool and psychology, so we included a game research expert in the project as well. The PUSE methodology facilitates the learning process and develops creativity, cognitive abilities, student motivation and attitude and it also provides equal opportunities for disadvantaged students. It can also improve the quality of teachers’ work.The PUSE Methodology doesn't claim completeness, i.e. it is not a closed collection of exercises. This couldn't have been its purpose. The Poly-Universe in fact is not simply a tangible tool or a closed-system puzzle, but an open math-art system which models the Universe, allowing a glimpse into its internal laws. The Poly-Universe, rooted in a special artistic vision, does not only inspire mathematics, but also triggers interdisciplinarity. The PUSE Methodology opens up the way for teachers and students, artists and scientists. We can all enter into Poly-Universe's spacious world, explore its complex realm and further discover its laws and regulations. While Poly-Universe offers scale shift, the methodology based on the tool offers a change of attitude for today's educational system – not in order to achieve small, medium or large bits of knowledge, but endless knowledge...(The project coordinator, Poly-Universe Ltd offers the license of the PUSE Methodology free of charge to the state and private school systems of EU countries)
