Upgrading
the APIS engine (newAPIS)
-
Originally, the APIS –Assessment Provision
through Interoperable Segments- engine was created by Strathclyde University
to increase interoperability of the IMS QTI specification in practice
by providing a liberally licensed open source implementation of the
non-controversial elements of the specification. They planned to implement a
modular item rendering engine in line with the version 2.0 of the
specification. GTI started by expanding the previous QTI version 2.0
implementation to reach completeness since the APIS state of the art version
does not address all the items in the specification [1]. Our
work proceeded to change the entire engine structure to convert it to QTI v2.1.
As this version accepts not just question but entire tests as well, we have
induced critical changes to the principal components of APIS including the main
engine class. Processing of test units thus has become more hierarchical, where
tests are considered both as units and groups of divisions. QTI v2.1. appends concrete characteristics for the test's divisions
including time constraints, navigation flow style, and others. These paradigms
and definitions were implemented and added to the improved engine, making it
necessary to adapt some of the previously existing processes and elements. newAPIS available at http://sourceforge.net/projects/newapis
Two releases:
o
apisQTI21v.1.0 (extension of APIS towards a complete
support of QTI v2.0 and including partial support for QTI 2.1): http://sourceforge.net/project/downloading.php?group_id=176392&use_mirror=kent&filename=apisQTIv21.rar&51908036
o
apistomcatv1.0 (same functionalities that the previous
version, but running on Tomcat): http://sourceforge.net/project/downloading.php?group_id=176392&use_mirror=osdn&filename=APISTomcat_1.0.zip&84529789
Integrating
newAPIS in SLeD(Coppercore)
-
The upgraded APIS engine is currently being integrated
through services within an experimental platform for running LD Units of
Learning. We are currently developing this platform, based on SleD, where different LD services
and tools are being integrated within a single framework. Upon completion,
APIS will be integrated within this framework where pilot Learning Design
courses will be serviced. This will enable the integration of assessment in the
workflow of LD activities, in particular, determining different learning paths
according to assessments results.
QTI
and Web 2.0
-
With the aim of providing new forms of communication
and interaction, GTI has proposed to integrate Web 2.0 services with QTI. As a
first example, GTI has developed a QTI assessment engine enhanced with web maps
from Google Maps [2]. The system enables the user to
interact with the map to answer questions, providing a more natural interface
for geographic information. The concept of map interaction has been introduced
to represent the different ways of processing the student actions on the map.
Depending on the selected map interaction, different spatial operations are
applied to validate the correctness of responses.
-
As a result, we have proposed a model for including a wide variety of user interactions of geographic
type with maps to perform assessment making use of Google Maps API; we
implement this solution through middleware
connecting Google Maps API to a modified QTI engine we have developed; we
create both an editor (see next section) of the assessments and a web player
based on the software indicated; and we tested this environment in a real
assessment situation (reference to be provided soon).
