Towards portable learning analytics dashboards - Andrii Vozniuk, Sten Govaerts, Denis Gillet
The document discusses the development of portable learning analytics dashboards that harness data to optimize the learning experience. It emphasizes the importance of software portability across learning environments and introduces various methods for unified data access, such as OpenSocial and ActivityStreams. The proposed solutions leverage open standards to allow the integration of analytics across multiple platforms, exemplified by the prototype implemented in the Graasp platform.

Editor's Notes
- #2 Good morning, I’m happy to see you all here, thanks for coming. My name is Andrii Vozniuk, I’m from REACT lab of Federal Polytechnic school in Lausanne, Switzerland.
- #3 Nowadays we observe a change (a shift) happening in the way we learn. Education transforms from having a well-defined and constrained path to more individual and flexible. Education is also becoming increasingly distributed (global) in nature. With the recent raise of MOOCs and other distance learning technologies, taking courses outside of the associated institution is becoming a common practice.
- #4 Nowadays we observe a change (a shift) happening in the way we learn. Education transforms from having a well-defined and constrained path to more individual and flexible. Education is also becoming increasingly distributed (global) in nature. With the recent raise of MOOCs and other distance learning technologies, taking courses outside of the associated institution is becoming a common practice. This shift creates new challenges that need to be addressed. It becomes much harder for teachers to observe, control and adjust the learning process. For instance, in the MOOCs it is simply impossible for a teacher to consider individual capabilities and preferences of each learner. But together with challenges there come opportunities. These days remote learning is usually mediated by a digital media which makes it possible to observe learning process in details. This observation is usually done by tracking actions of students in a learning platform and generates their digital traces. A natural intentions is to collect this data and use it to improve learning. [Now there is a common understanding that data should be used to improve learning] Increasingly more digital tools are being used in a classroom, which allow to collect traces of students Leveraging educational data

- #6 That’s exactly the goal of recently emerging field of learning analytics. So what is learning analytics? According to Siements et. al. LA is “the measurement, collection, analysis and reporting of data about learners in their context, for purposes of understanding and optimizing learning and the environment in which it occurs”. There is a strict definition of the LA on the slide but what it says is that the goal is to make use of the data to improve learning. Such an improvement could possibly be an early prediction of a drop out, or just informing the teacher regarding progress of a class, or just showing to student their performance compared to the distribution of a class to make them more aware of their results. Numerous studies show that integrating learning analytics into the learning process could improve the outcome. But existing popular online learning management systems (LMSs) and personalized learning environments (PLEs) lack or provide limited LA dashboards. Let’s have a look how LA component is integrated into existing learning systems. TODO: LA component often comes in a form of a learning dashboard – show few examples Self-monitoring for learners Awareness for teachers and administration It works
- #7 And indeed it is being integrated in one way or another into existing learning systems. For example, here we see Blackboard, a popular system. It has a learning component. Here we show an example of a component to increase student’s awareness and motivate them by showing their progress relatively to the progress of classmates.
- #8 Another example is a Moodog plugin for Moodle which presents visualization of student activities based on Moodle logs. TODO: Replace with Purdue signals

- #10 TODO: higher resolution And the third example that I would like to show is Google Analytics, which is often used for online courses to monitor student behaviour. The common between the demonstrated approaches and actually the common way to deploy analytics is to build an analytic dashboard. Summary: Existing learning dashboards are barely portable: once deployed on a learning platform, it requires considerable effort to deploy the dashboard elsewhere.
- #11 Some configuration might still be required Cost is considerably lower than building from scratch Why portability? Portability offers freedom Openness leads to better adoption understand the concept of portable learning dashboards, we first define software portability in general. Software portability is the ability to run the same software on different platforms with no or little effort. Some configuration of LA tools on a new platform might still be required but its cost is considerably lower than developing the tools from scratch. Our goal is to achieve portability be implementing learning dashboards as external pluggable components and using well-defined interfaces with a learning platform. TODO: should better explain why portability is important. Now it’s hard to understand why we are working on this problem. Learning system perspectives: Structural View Dynamic View
- #12 TODO: Add three images with blocks to show different types of architectures Our goal Implement LA dashboard as a pluggable component Use standardized and open interfaces with the platform Hence learning systems are extended with plugins or augment Summary: Existing learning dashboards are barely portable: once deployed on a learning platform, it requires considerable effort to deploy the dashboard elsewhere. Ecosystem lock-in Data is locked Analysis tools are locked
- #13 In order for LA tools to function, a learning platform must provide access to its stored data. Such data represents dynamic (behavioural) and static (structural) views of the platform.

- #18 TODO: Visualize widgets and metawidgets
- #19 Classical three tiers Built upon open standards Can work for existing systems Customizable
- #20 TODO: Ask Evgeny regarding support of OpenSocial in Moodle
- #21 To sum up, we are strong believers that the openness and portability of learning analytics tools will increase their adoption. We also believe that to make a solution (architecture) adopted it is required to build it upon open standards. Existing learning dashboards don’t promote are barely portable: once deployed on a learning platform, it requires considerable effort to deploy the dashboard elsewhere. Hence in this talk we proposed a novel approach to build and deploy learning analytics dashboards in multiple learning environments. Our approach allows to port dashboards with no additional cost between learning environments that implement open specifications (OpenSocial and ActivityStreams) for data access and use widget APIs. We suggest constructing dashboards from lightweight web applications, namely widgets. We propose to facilitate reuse by sharing the dashboards and widgets via a centralized analytics repository. TODO: what the systems that wants to make a use of it will need to do?
