I find the log file data to be an excellent means to engage students and see how their actions can impact on outcomes.  This provides a mechanism for students to not only reflect but take responsibility in decisions ones make. it is a great learning tool...  

This is one of the best exhibits I saw for student learning.  Great job.  

Thanks for your comment, Christine.  We are lucky to have the log data as a tangible trace of what students did, since it's a lot for them to take in when they are actually in the museum.  Interestingly, the log data in this case only records the results of what they did - NOT their actions - so it's been quite a process to figure out how to help the students recognize where they had an impact on the state of the system.  I think students would greatly benefit from a return trip to Connected Worlds after they have had a chance to reflect so that they could take more "informed responsibility" for their decisions.  

Hi Sally -

As Ada said, some of the video is sped up - but even so, there is a LOT going on in Connected Worlds and even after visiting it a bunch of times, I have trouble knowing where to focus - so I can imagine it's even more difficult for kids who just get half an hour.

Ada gave a good summary of what we've seen as evidence of systems thinking - but I have to admit that we've only had this one experience so far.  In a larger study, we'd want to ask students to do something more controlled, like drawing a concept map of the system or perhaps responding to a scenario we'd present.  I would say that most of the students understood that the amount of water each biome had depended on how much each of the other ones had.  One girl told me, though, that even if they had agreed to split the water equally among the four biomes, it would be difficult to achieve because of the way the logs and the water interacted, so she understood both the desirability of that situation and its difficulty.  

Thanks Leilah:

Having spent time looking at innovations that were further developed as part of I-Corps L, I-Corps  I see a lot of potential here for scaling the innovation based on the core principles and the basic embedded technology

That's kind of you to say! We've looked at a lot of ways to extend our work, but I hadn't thought of I-Corps. 

Hello DeLene,

For our first trials, Andee stepped into the teacher role. We didn't want to throw a teacher into the session cold, and right now we're building out the experience, so we haven't yet spent as much time on the professional development side. That said, we would eventually want to have the teachers take on a more integral role. We've started by creating pre-visit materials for teachers (Ada worked extensively on that), and the next step would be to create a post-visit guide to help teachers use the visualization with the students (I'm sure Andee could say more about how we might structure that - I'm the museum person on the grant and so don't claim to be a teacher PD expert). If you had any thoughts about what we might need to do to better support teachers, we'd love to hear your ideas!

Hi DeLene -

To add to Leilah's comments about the teacher's role:

Eventually, we would hope both to provide a post-visit guide that would include general instructions for a teacher in how to use our visualization - but our data science algorithm that identifies distinct patterns of water flow would also allow us to point out to the teacher where particularly interesting parts of the simulation occurred, so that she could focus class discussion on those.  For example, we might highlight for the teacher a period of time when one biome was getting all the water - and she could then ask students to talk about what was going on during that period.  We're hoping to explore this a bit in the remaining time of our project.

Hello Acacia,

While we're not currently working on scaling up, there is potential (see the communication with Alan above). Learning impact at the teacher level - well, I'm the informal learning researcher on the team, so I might not be best positioned to comment on this, but one thing I think we all noticed was that for both the students and the teacher, looking at the data *you* generated was a powerful way to open the door to data interpretation using visualizations. One teacher remarked that the same students who were so fluidly telling stories using our data visualizations were the same group who had been struggling with line graphs in math class. So I'd suspect that teachers might have to recalibrate what they expect their students to be able to do.

We don't have a dashboard - our visualization is structured as a multi-purpose tool, not a guided inquiry experience (like WISE or Progress Portfolio), so it's not clear (to me) what kind of actionable information a dashboard could give the teacher. (We can't show, for example, what percentage of students have finished a task, because the tasks are external to the software). As you suggest, we envision the teacher playing the role of a facilitator. For our classroom trial, we gave the students a worksheet with a few questions to answer using the visualization. Then Andee walked around the room answering questions and giving assistance when needed.

I see that you listed your role as "facilitator" - we'd love to hear any ideas you might have about how we could make the experience more amenable to facilitation!

Engaging discussion and collaboration is key for educational success. I appreciate how your platform embraces just that. As you fine tune your tool, I will be interested in understanding the role of the teacher as a facilitator of discussion and thinking. In particular, using science inquiry to drive reflection on science and engineering practices in the real world. Very exciting!

Hi Jim!

Great questions, a lot to unpack here.

Re. the effect of introductions: NYSCI has experimented with a number of ways to introduce learners to CW, too many variations to detail here. We have the ability to create CW sessions with built-in pauses (i.e., reflection periods), and to "chunk out" the session into different episodes, so we can do a lot of creative things with how we stage the experience. We've created flood and drought scenarios, and for a while had a fantasy story wrap-around that positioned visitors as an "away team" to an alien planet, tasked with collecting information on the flora and fauna. One basic strategy we find effective is to let visitors play with abundant system water so they can get acquainted with the natural environments, pause, and then ratchet back the water present in the system to give them more of a challenge to think systemically. 

We find it's hard to give visitors a lot of instructions on-site, because they are itching to get into the simulation - even if we tell them, they're too busy looking to listen. So for this work, we created pre-visit materials to help acquaint the students with the kinds of plants and animals present in each biome.

WRT group behaviors - we see a lot of great variations. We've experimented with giving visitors roles (indeed, that's what we did here), but visitors often self-assign. One thing that doesn't work very well, though, is a total free-for-all. Splitting visitors into biome "teams," even if we don't give them more specific roles, seems to introduce just enough tribalism that they then can self-organize. I've seen school groups spontaneously create representative democracies (nominating a person from each biome group to negotiate water distribution, for example), and even give each other more abstract, less action-oriented roles (e.g., "watchers" who just monitor for changes). One thing we say at NYSCI is that CW is just as much about giving learners practice with collaboration as it is about giving them practice with complex systems.

WRT visualizations - in a parallel grant we've begun to more systematically explore the design factors involved in making accessible CW visualizations. For this grant, we've just completed and tested our first implementation, and got something of a ceiling effect - the kids did NOT struggle with making sense of the visualizations, or linking between the visualizations, which we didn't expect. We really thought we'd expose issues with the visualization that needed correction! So now we're thinking more integratively, about how the visualization design and classroom activity can be designed to be more complementary.

 

 

Thanks, Liz!  I know you have in-depth knowledge of complex systems as a scientist, so your comment means a lot.

Thanks, Liz!

Thanks for your comment, Katie.  You are totally right that it's a much more challenging task to work with the public who are just wandering in to Connected Worlds as part of a day at the museum.  That's why we started with a more controlled situation in which we actually had a more time with visitors - although it was just two class periods bracketing their half-hour in the museum.  Leilah's been working on a way to visualize some of the data DURING visitors' time in the space and providing the visualizations to the interpreter stationed in Connected Worlds, so I'll let her add more details about that project.

Hi Frank, thank you for your interest! We first introduce the students to how plants and animals are linked in each habitat in the pre-visit materials. Their experience in the Connected Worlds environment reveals more of the intricacies of the whole system, namely, the challenges of diverting water, and the difficulty of maintaining a healthy overall system with limited resources. Their experiences, both agentive and observed, are recorded in the data logs and the abstracted video of the space that shows the water flow. These support their recall of their session and help them to step back and see the bigger picture, what everyone else was doing, and how their actions affected the rest. 

Connected Worlds is available to the public, but our materials and data visualizations are currently available for each class visit session we facilitate. 

Thanks for this "hard question," DeLene!  Much of what we learned was about the difficulty of working with log files - so here is some advice for other people who are interested in log files from an already-established simulation as a source of data about users' experiences and, potentially, learning.  Developers set up log files for their own purposes - and these are not necessarily the same as learning scientists' purposes.  So, for example, the log files for Connected Worlds only have the state of the system recorded, as they were built to support the projected display.  We were interested in users' actions, but had no way to access them directly - rather, we had to either infer them ourselves or ask the students to remember them when they viewed the effects in the recap.  We were a bit naive going in to this project about how much time it would take to get logs that worked for us - we actually spent much of the first year working with the developers to expand and tailor the logs for our use.
