A student videoconference with NASA

Getting students involved with global citizen science projects is a great way to engage kids with science and to instil curiosity and a desire for lifelong learning. There are many such projects available, and this week some students at my school were fortunate enough to participate in a videoconference with a scientist from NASA!

Joining us from NASA for this videoconference was Peter Falcon, the NASA/JPL Earth Science Outreach Coordinator, who also works with the CloudSat Education Network

The session began with my students giving the traditional Thai greeting to Peter, before some Matayom 3 (Grade 9) students gave a presentation about the effects of the latest El Nino event here in southeast Asia (thanks go to my colleague Ajarn Craig Wardman for helping the students prepare for this).

Peter was impressed at the level of detail and information provided by our students. He next gave us a 30 minute presentation on some of the background to the CloudSat project and how the data collected by students around the world are used by NASA scientists to calibrate their satellite instruments. He also explained how the CloudSat project nearly came to a premature end when the satellite's solar panels stopped working correctly. Fortunately, after several months of trial-and-error tweaking, the NASA scientists came up with a solution which allowed the CloudSat satellite to resume its observations, and the project was saved.

This kind of collaborative, global project can be used to get students engaged across all of the STEM subjects. It can even lead to a STEAM-based approach, with art added to the mix of science and technology. For example, Peter mentioned some schools have students write poetry about clouds, in addition to learning about the earth and climate science aspects. 

Overall, holding this videoconference served two main purposes. Firstly, it allowed those students who had already participated in CloudSat to see how their data helped NASA scientists with their research. Secondly, it hopefully aroused interest in the younger students so that they will wish to take part in the CloudSat project in the future. This seems to have worked - later this week some students will be participating in their first CloudSat observations!

A global classroom collaboration

Over the last month or so my students have been participating in a global classroom collaboration. This has been an exciting foray into my first proper collaboration of this sort, and was initiated via a Twitter conversation with a colleague, Jodie, in the USA. 


A screenshot from the Flipgrid web app.

The plan for the initial lesson can be found here. Briefly, we each had our classes do research about our respective local biomes, surroundings, and cultures. The students then developed clues relating to their research. I had my students write the clues out as scripts which would form the basis of video messages they recorded using the Flipgrid app. The students in my colleague's class then viewed the videos, and my students viewed theirs. The students then submitted written questions to each other using Padlet, with which to try & glean more information in order to guess the location of each other's school. The great thing about this approach is that it can be done asynchronously, avoiding any difficulties arising from being in very different time zones. 

I was very impressed with the level of engagement my students showed during the development of their clues, and they put a lot of thought into them. Since they are English language learners I assisted them with the development of their scripts, mainly just to remove words or phrases that would give away our location too easily.

The next lesson I had students download the free Flipgrid app onto their smartphones and enter the hashtag for our collaborative grid. This had been set up previously by Jodie, using her paid Flipgrid account. Once the grid has been set up, anyone can be invited to upload short video recordings to it via the app. These subsequent users do not pay any additional sign up fees. We experienced no problems downloading the app or accessing the class grid. 

I let my students find somewhere quiet to record their videos, and made sure they used areas where there were no distinguishing features that would have given their location away. They rehearsed their scripts briefly, then recorded and uploaded their video messages to Flipgrid. This was a very straightforward process, with no technical difficulties presented by using the app to record the videos. 

My students spent a number of periods working on this project, and were very engaged and actively participating throughout. Overall, their feedback from an evaluation questionnaire they completed following the project was extremely positive, as exemplified by the following comments (verbatim):
  • I learned a lot from the Flipgrid project, one of them being to not use the country or places you live as a barrier for your learning
  • I learned about biology in other country, such as climate and biomes. I also got to know their culture and lifestyle which is very interesting. 
  • I learned both of biodiversity in Thailand and Texas that I've never known before.
  • This project should continue. I really enjoyed it and I'm sure other students will enjoy it too.
The one drawback to this project was its timing, in that we began just before the Christmas/New Year break, and one of my students noted in their evaluation feedback following the project that this had had a dampening effect: 'May be not to use during the holidays? It was so exciting at first but then they had their holidays followed by our breaks so we kinda forgot about it'. This was a fair point, but as we all know the reality of school schedules means that we can't always fit things in where we would like. In the future, though, I would try to avoid spreading an activity such as this over an extended break. 

I have seen some educators criticise global classroom collaborations as being undertaken simply because technology now allows this. However, based on my students' own comments, together with my observations, this approach does seem to have positive learning outcomes. I feel that the main content-driven learning occurred during the initial lesson, when students were developing their clues relating to their local environment, such as which biome they are located in. The learning which took place in subsequent lessons related more to language skills, for example my ELLs trying to understand native English speakers talking at normal speed. It also offered students in their different countries cultural insights to see what their differences were and also their similarities - would the US teenagers have guessed that Thai teenagers' favourite foods were pizza and pasta for instance!

Overall, I feel that this was a successful activity, both in terms of the content learned and the level of student engagement. I would be happy to hear others' views on this, or similar undertakings that they have done.
