urban and rural environments from the physical 
world, and the easy learning curve of this digital 
game. The immense popularity of this game and 
the ability to alter specific mechanisms through 
‘mods’ and ‘plugins’ also contributed to our 
decision. 
In a project-based assignment, the children of 
the Technasium in Lelystad (the Netherlands) 
were challenged by Rijkswaterstaat to develop 
sustainable spatial plans for the second phase of 
the Marker Wadden (‘Marker islands’) in Lake 
Markermeer. Together with the National Nature 
Conservation Agency (Natuurmonumenten) and 
the dredging company Boskalis N.V., 
Rijkswaterstaat aimed to improve the water 
quality and biodiversity of the Markermeer-lake 
by creating islands with silt from the bottom of 
the lake. The construction of the Houtribdijk in 
the 1950s from Enkhuizen to Lelystad had 
blocked the flow of silt to open sea, and as such, 
during the second half of the 20th century, the 
vegetation of Lake Markermeer was covered by a 
thick layer of mud. To restore the water quality 
and biodiversity, islands were created with this 
silt during phase one of the Marker Wadden-
project between 2013 and 2015. 
School children were asked to investigate the 
possibility to use the islands not only to enhance 
the ecological quality of the area but also to 
generate sustainable energy (e.g., solar, wind, 
water power) and/or to create places where people 
can recreate (e.g., a harbor and visitor center). For 
this, we reconstructed in Minecraft the complete 
Markermeer, the islands and the landscape objects 
that lay around this lake. This virtual environment 
functioned as the canvas that the school children 
could use for their three-dimensional spatial 
designs. 
2.2 Minecraft 
Minecraft is a so-called open world game, 
released in 2011 by the Swedish company 
Mojang. Two game modes are provided: survival 
and creative. The survival mode allows the player 
to roam in a borderless (open) world. The primary 
goal is to survive in an environment full 
of dangerous creatures by building a house and 
producing food. In the creative mode, on the other 
hand, players already have access to all 
the materials and tools, which allows them to 
build anything that they can imagine. This mode 
proves to be an excellent starting point to engage 
learners in sustainable spatial planning. Moreover, 
the multiplayer option allows players to work 
together on the assignment. 
Location plays an important factor in 
Minecraft. The open world consists of different 
regions with their own (visual) characteristics, 
place identity, and ecosystems. To navigate in this 
virtual world, the player has to think in a three-
dimensional way as it is possible to move freely 
in all kinds of directions. Reasoning about 
distances, directions, and movement fosters the 
spatial thinking process. The game stimulates 
school children to use their mental rotation skills 
to create, adjust, destroy and recreate entire 
landscapes and objects. As such, various scholars 
have argued that Minecraft can efficiently 
contribute to the development of the learners' 
geographical and spatial thinking capabilities 
(Mørch and Thomassen, 2016; Nebel et al., 2016; 
Nguyen and Rank, 2016; Scholten, 2017).  
Four game characteristics of Minecraft prove 
to be very interesting for educational purposes. In 
the first place, the player can design entire 
landscapes with its unique architecture, flora, and 
fauna. Some players reconstruct existing places 
and objects, such as the Eiffel tower or Dam 
Square in Amsterdam; others create fantasy 
worlds with castles, dungeons, and dragons. An 
entire world can be created with the use of 
rectangular blocks.  
These Lego-like blocks have their own 
characteristics and textures and represent the 
building materials of the physical world. With 
these blocks, players can, for example, transform 
“silt-blocks” into grass or stone. Or they can 
create buildings with various "wood- or stone-
blocks”. This high level of interactivity is a 
second game mechanism, which makes Minecraft 
attractive for educational purposes.  
Thirdly, Minecraft stimulates players to work 
together on a specific building project. 
In particular, children find it very engaging to 
"meet" in the virtual Minecraft world and to chat 
about daily life, as well as to impress each other 
with their building skills and creations. As such, 
Minecraft is a safe environment, where young 
people can escape from reality.  
Fourth, the massive popularity of Minecraft 
has resulted in the creation of numerous "mods" 
and "plugins" to change the game mechanics and 
appearance of the game in many ways. The large
