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
