The Semideus School is now available

The Semideus School is now available on the App Store for iPad! We are looking forward to make research collaboration with schools.


The Semideus School game is a really fun way to learn fractions, decimals, and percentages. By playing Semideus, learners improve their ability to perceive and estimate rational numbers in multiple forms. The adventure happens in Mount Olympos. The task of the player, Semideus, is to find the gold coins that Gobolas the Goblin has stolen from Zeus. On the way to Mount Olympos, Semideus has to chase the goblin, seek the coins, avoid traps, and crush math based enemies.

– Rational number magnitude estimation, comparing, and ordering
– Numerator / Denominator notation
– Proper fractions, improper fractions, mixed numbers, decimal numbers, and percentages
– Equivalence
– Density of rational numbers
– Adding, subtracting, expanding, and reducing fractions

Attention! Semideus School is targeted for our research collaborators (a limited number of teachers and researchers) that conduct research in schools. In order for a student to play the Semideus School game, a teacher/researcher must register to the Semideus School service and obtain game access codes for students.

Special Issue on Digital Games for Learning Mathematics

We have recently published as guest editors a special issue  on digital games for learning mathematics (International Journal of Serious Games). Five papers shed light on usefulness of mathematics learning games and provide knowledge that support development of high quality mathematics learning games. Also, these journal articles provide knowledge about effectiveness of mathematics learning games, show innovative technological and pedagogical solutions that facilitate learning of mathematics with games. In addition, they provide empirically grounded design principles for mathematics learning games, and consider mathematics learning games as assessment tools.

Our own paper in the special issue is titled as

Using video games to combine learning and assessment in mathematics education

Abstract of our paper:

One problem with most education systems is that learning and (summative) assessment are generally treated as quite separate things in schools. We argue that video games can provide an opportunity to combine these processes in an engaging and effective way. The present study focuses on investigating the effectiveness and the assessment power of two different mathematics video games, Semideus and Wuzzit Trouble. In the current study, we validated the Semideus game as a rational number test instrument. We used it as a pre- and a post-test for a three-hour intervention in which we studied the effectiveness of Wuzzit Trouble, a game built on whole number arithmetic and designed to enhance mathematical thinking and problem solving skills. The results showed that (1) games can be used to assess mathematical knowledge validly, and (2) even short game-based interventions can be very effective. Based on the results, we argue that game-based assessment can create a more complete picture of mathematical knowledge than simply measuring students’ accuracy, providing indicators of student misconceptions and conceptual change processes.

Second prototype of Semideus game

Semideus is a math learning game about rational numbers. The game is based on recent research findings on numerical development. The gameplay is founded on tasks that require working with number lines. This video presents the current state of our game on March 2015.

Call for Papers: Special issue of International Journal of Serious Games

Acquisition of mathematical skills is crucial for today’s society. It
has been argued that in individual level, insufficient mathematical
competencies may be even more harmful to career prospects than reading
or spelling deficiencies. This is to say, that in society level
mathematical deficiencies can lead to immense costs. Thus, it is
important to develop more engaging and effective methods that can be
used to enhance children’s conceptual understanding of mathematics,
develop mathematical thinking processes and improve arithmetical
skills. Digital games provide interesting possibilities to support
these goals and one can easily find great deal of online games and
apps targeted for learning mathematics. Unfortunately, only a fraction
of existing mathematics learning games is founded on theoretically
sound principles, relies on good pedagogical practices and really
utilizes the possibilities that game technologies provide for learning.

The learning effectiveness of physically activating multiplayer game environments: Learning by creating games versus learning by playing games

We are proud to present our research project titled as “The learning effectiveness of physically activating multiplayer game environments: Learning by creating games versus learning by playing games”. This Academy of Finland (Future of Learning, Knowledge and Skills TULOS Research Programme) funded four-year project has started from the beginning of the 2014 and ends to the end of the 2017. It is about the effectiveness of games and game creation in the context of learning mathematics.
