Re: [Sugar-devel] The quest for data

May 2014 bring good deeds and cheer :-) Here's a blog post on the different approaches (that I know of) to data gathering across different projects. Do let me know if I missed anything. cheers, Sameer http://www.olpcsf.org/node/204 Thanks for putting together the summary, Sameer. Here is more information about my xo-stats project: The project's objective is to determine how XOs are used in Nepalese classrooms, but I am intending for the implementation to be general enough, so that it can be reused by other deployments as well. Similarly to other projects you've mentioned, I separated the project into four stages: 1) collecting data from the XO Journal backups on the schoolserver 2) extracting the data from the backups and storing it in an appropriate format for analysis and visualization 3) statistically analyzing and visualizing the captured data 4) formulating recommendations for improving the program based on the analysis. Stage 1 is already implemented on both the server side as well as the client side, so I first focused on the next step of extracting the data. Initially, I wanted to reuse an existing script, but I eventually found that none of them were general enough to meet my criteria. One of my goals is to make the script work on any version of Sugar. Thus, I have been working on process_journal_stats.py, which takes a '/users' directory with XO Journal backups as input, pulls out the Journal metadata and outputs them in a CSV or JSON file as output. Journal backups can be in a variety of formats depending on the version of Sugar. The script currently supports backup format present in Sugar versions 0.82 - 0.88 since the laptops distributed in Nepal are XO-1s running Sugar 0.82. I am planning to add support for later versions of Sugar in the next version of the script. The script currently supports two ways to output statistical data. To produce all statistical data from the Journal, one row per Journal record: process_journal_stats.py all To extract statistical data about the use of activities on the system, use: process_journal_stats.py activity The full documentation with all the options are described in README at: https://github.com/martasd/xo-stats One challenge of the project has been determining how much data processing to do in the python script and what to leave for the data analysis and visualization tools later in the workflow. For now, I stopped adding features to the script and I am evaluating the most appropriate tools to use for visualizing the data. Here are some of the questions I am intending to answer with the visualizations and analysis: * How many times do installed activities get used? How does the activity use differ over time? * Which activities are children using to create files? What kind of files are being created? * Which activities are being launched in share-mode and how often? * Which part of the day do children play with the activities? * How does the set of activities used evolve as children age? I am also going to be looking how answers to these questions vary from class to class, school to school, and region to region. As Martin Abente and Sameer mentioned above, our work needs to be informed by discussions with the stakeholders- children, educators, parents, school administrators etc. We do have educational experts among the staff at OLE, who have worked with more than 50 schools altogether, and I will be talking to them as I look beyond answering the obvious questions. For visualization, I have explored using LibreOffice and SOFA, but neither of those were flexible to allow for customization of the output beyond some a few rudimentary options, so I started looking at various Javascript libraries, which are much more powerful. Currently, I am experimenting with Google Charts, which I found the easiest to get started with. If I run into limitations with Google Charts in the future, others on my list are InfoVIS Toolkit (http://philogb.github.io/jit) and HighCharts (http://highcharts.com). Then, there is also D3.js, but that's a bigger animal. Alternatively or perhaps in parallel, I am also willing to join efforts to improve the OLPC Dashboard, which is trying to answer very similar questions to mine. I am looking forward to collaborating with everyone who is interested in exploring ways to analyze and visualize OLPC/Sugar data in a interesting and meaningful way.

Re: [Sugar-devel] New year, new testing image
Hi Mattew, Here we have two alternatives: * Filter our data with a database of serial numbers. * Provide two different images, one for testing, one for the AU deployment. If you ask me, I prefer (obviously) not need to do 2 different images, but is not too difficult (just change one rpm), but time consuming.

Would it be for testing only (yourself?) or actual major deployments? Very briefly, the AU software now includes a statistics-collection software that sends data to our servers matching the serial number of the XO against our local serial-numbers database. This means that if you're going to deploy the image on, say 100 laptops, those will then sync data to our db which results in serial numbers not matching. I am worried about the scale of this issue, which might fill our db with incoherent data so perhaps (Martin, Gonzalo?) we should think about a way to prevent any confusion in case the AU image is used somewhere else around the world.

So I am seeking for a way to share some code/ressources from a common repository reserved for that purpose, to the different official activities : is that simple to do in Github (so in Sugar gitorious) ?

But more importantly, to make this meaningful, we need more data. I like this approach as well because the aggregation is offloaded to CouchDB through views and reduce/rereduce so we can have a fairly independent choice of Javascript-based visualization frontend, be it Google Charts (https://developers.google.com/chart/) or D3.js (http://d3js.org/). It's good to know what the activities are that are used most, so one can come up with a priority list for improvements, and/or focus developer attention. CouchDB allows to pull data together from different instances, which should make aggregation and comparisons between projects possible. And for projects that are not online, the data could be transferred to a USB stick quite easily and then uploaded to any other DB instance. True. CouchDB will allow for aggregation across classes, schools, districts, etc. Depending on the willingness of participation of different projects, we can certainly go cross-project. Even if these views are not made public, they will be useful. For instance, I would love to compare my Jamaica projects with my India projects with my Madagascar projects. Is there a task/todo list somewhere? Not that I know of, but we can always start one on the sugarlabs wiki. Anybody have suggestions?

And how can we answer these questions reliably? Even though most of us have experience in deployments and their needs, we are engineers, not educators, nor decision makers. Agreed. It would be helpful to have a conversation on what the various constituencies need (different from want) to see at their level. The child, the parents/guardians, the teacher, the principal/administrator, and educational bureaucracy. We should also consider the needs of those of us who have to fundraise by showing progress of ongoing effort. I am sure that most of our collection approaches cover pretty much the trivial stuff like: what are they using, when are they using it, how often they use it, and all kind of things that derive directly from journal metadata. Plus the extra insight that comes when considering different demographics True. Basic frequency counts such as frequency of use of activities, usage by time of day, day of week, scope of collaboration are a few simple one. Comparison of one metric vs the other will need more thinking. That's where we should talk to the constituents. But, If we could also work together on that (including the trivial questions), it will be a good step forward. Once we identify these questions and figure out how to answer them, it would be a lot easier to think about visualization techniques, etc. If the visualization subsystem (underlying tech pieces) are common and flexible, then we can start with a few basic templates, and make it extensible, so we can all aggregate, collate, and correlate as needed. I'll use an example that I'm familiar with. We looked at CouchDB for two reasons: 1) It allows for sync over intermittent/on-off connections to the Internet and 2) CouchDB has a views feature which provides selective subsets of the data, and the reduce feature does aggregates. The actual visual is done in Javascript. Here's the example Leotis had at the OLPC SF summit (http://108.171.173.65:8000/). What you guys think? A great start for a great year ahead!

If others have seen/done so, it would help to hear from them. I know that in conversations and presentations to decision makers, the usual sore point is can you show us what you have so far? For Jamaica, we have used a basic exploratory approach on the Journal data, corroborated with structured interviews with parents, teachers, etc. So, for instance, the data we have shows a relatively large frequency of use of TuxMath (even with different biases). However, we have qualitative evidence that supports both usage of TuxMath and improvement in numeracy (standardized test). We can support strong(er) correlation, but cannot really establish causality. The three data points put together make for a compelling case. I think this is a really important point to emphasize: None of these approaches to evaluation provides the complete picture, but all of these used in aggregate can provide useful insights. Here at OLE Nepal, we already use standardized testing to compare students performance before and after the program launch. We also follow up with teachers through conversations using surveys on regular support visit. I agree with Sameer that supplementing those with statistical data can make for a much stronger case.

Re: [Sugar-devel] The quest for data
Dear Sameer, all, That's a very interesting blog post and discussion. I agree that collecting data is important but knowing that are the questions aimed to be answered with that data is even more so. If you need help with that last bit, I could propose to use the journal data as a use-case for the project KnowEscape ( http://knowescape.org/ ). This project is about getting insights out of large knowledge spaces via visualisation. There is wide (European) community of experts behind it coming from different research fields (humanities, physic, computer science, ...). Something useful could maybe come out... I would also like to refer you to the project ERS we have now almost finished. This project is an extension of the ideas behind SemanticXO some of you may remember. We developed a decentralised entity registry system with the XO as a primary platform for coding and testing. There is a description of the implementation and links to code on http://ers-devs.github.io/ers/ . We also had a poster at OLPC SF (thanks for that !). In a nutshell, ERS creates global and shared knowledge spaces through series of statements. For instance, Amsterdam is in the Netherlands is a statement made about the entity Amsterdam relating it to the entity the Netherlands. Every user of ERS may want to either de-reference an entity (*e.g.*, asking for all pieces of information about Amsterdam) or contribute to the content of the shared space by adding new statements. This is made possible via Contributors nodes, one of the three types of node defined in our system. Contributors can interact freely with the knowledge base. They themselves take care of publishing their own statements but cannot edit third-party statements. Every set of statements about a given entity contributed by one single author is wrapped into a document in couchDB to avoid conflicts and enable provenance tracking. Every single XO is a Contributor. Two Contributors in a closed P2P network can freely create and share Linked Open Data. In order for them to share data with another closed group of Contributors, we haves Bridges. A Bridge is a relay between two closed networks using the internet or any other form of direct connection to share data. Two closed communities, for example two schools, willing to share data can each setup one Bridge and connect these two nodes to each other. The Bridges will then collect and exchange data coming from the Contributors. These bridges are not Contributors themselves, they are just used to ship data (named graphs) around and can be shut-down or replaced without any data-loss. Lastly, the third component we define in our architecture is the Aggregator. This is a special node every Bridge may push content to and get updated content from. As its name suggests, an Aggregator is used to aggregate entity descriptions that are otherwise scattered among all the Contributors. When deployed, an aggregator can be used to access and expose the global content of the knowledge space or a subset thereof. One could use ERS to store (part of) the content of the Journal on an XO (Contributor), cluster information as the school level (Bridge put on the XS) and provide higher level analysis (Aggregator). The best things about ERS, I think is that: * It can store and share any data that consists of property/values about a given thing identified with a unique identifier * It is off-line by default, all the upper level components are optional. So is the connectivity to them * It's conservative in terms of bandwidth used The creation of graphs could be done at every level to get some statistics on the XO, on the XS and at a more global level. All these potentially using the same code as the data is always stored using the same model (a variant of JSON-LD). We are now finalising a small social-networking activity to demotest ERS. You can easily play with it using the virtual images we put on the site. Here is a video showing it running: https://vimeo.com/81796228 Please have a look and let us know how what you think of it :-) The project is still funded for a bit less than three months and we would really like it to be useful for the OLPC community (that's why we targeted the XO) so don't hesitate to ask for missing features!

[Sugar-devel] Collaboration support for sugar web activities
Hello, Thanks to Manuel Quiñones, I was able to check out in detail a Mozilla project - https://togetherjs.org TogetherJS is a javascript library for... well, collaboration. It consists of a client side and a server side. The server side acts only as a bridge between clients and it repeats the messages it recieves. It's nothing complicated, nothing interesting, I'll ignore that for now. Once in a TogetherJS session, users can communicate with each other (there is a chat offered by TogetherJS). User's pointers are also shared (if desired). There also other features like audio chat and video syncing, which are somewhat experimental (by what I understood from the docs). More importantly, except these features, the library comes with an API, which will allow web activity authors to sync different objects from the page. Everything is controlled by javascript. I've already started on integrating TogetherJS with sugar. In order for two users to be in the same session, they must share one togetherjs ID. I've based this ID sharing on telepathy - like the current activity invites are sent. After having the same ID, the session is then supported by the upper mentioned server. Mozilla has offered such a server for public use, but I do not think that sugar should be using it. I think that it would be best if this is handled via telepathy, just like the current activities communicate. As mentioned above, the server has no special role other than receiving messages and sending them to all participating clients. An alternative would be to host such a server for sugar's needs (the server is a single nodejs script). I do not like this way, as it would cause web activities to depend on an Internet connection. I hope that by the end of the week I can show a web activity having collaboration support based on TogetherJS.
