WME vs. HeyMath
HeyMath is a successful web-based approach that appears to have
similarities to WME. Detailed technical information
on the commercial HeyMath is hard to find making a detailed
comparison to WME difficult.
However, some significant differences are apparent.
- HeyMath is not open. WME uses open technologies
such as DOM, MathML and SVG and follows W3C recommendtions.
- WME is a distributed system of self-contained websites and
features inerchangeable and interoperable educational components through
well-designed interfaces. HeyMath makes no such claims.
- WME emphasizes hands-on experiments, dynamic teacher control of
student lesson pages and immediate assessment of each student's comprehension.
HeyMath seems to deliver fixed HTML, Flash animations and video recordings.
- WME offers per-school, per-teacher and per-class adaptation
for an easy-to-deploy and flexible-to-apply system. HeyMath does not
appear to use this open distribution approach.
- A Web-services approach and
a special-purpose markup language (MeML) can combine to make
WME an open system that is powerful and extensible.
We see no such plans for HeyMath.
- HeyMath! seems to use visual representation of mathematics as static images,
which makes impossible to share content with semantics. The WME employs MathML
which enables to publish mathematical content dynamically allowing users to
create/submit/edit their own expressions encoding both mathematical notation
and its associated meaning.
