Heatmaps are an incredibly useful tool and ingeneous way of visualising and displaying data and relationships between columns and rows, whatever they may be. Basically, “a heat map is is a graphical representation of data where the individual values contained in a matrix are represented as colors”.
I first came across “heatmaps” in my studies in Molecular Biology at the University of Cape Town where they are very common to show gene expression of microarray data under various conditions and help identify clusters and patterns. For example, see the image below with the typical red and green colour scale used.
Last week I got back from the US after attending OpenCon in Washington DC from 12-14 Nov. Arriving the day after the US election results came out, the mood in the capital was very somber as people were trying to grapple with what just happened. Even walking down the streets, I caught fragments of many conversations discussing the recent events. I also arrived on Veteran’s Day, and as I had some time to do a bit of sight seeing, I decided to walk along the Mall, and also to the end where most of the war memorials are located.
I arrived at a very misty, drizzly St Anne’s and was quickly transported back in time to the atmosphere the thick, refreshing mist used to create around the school, no matter the time of day. I hadn’t quite realised it was also the last day of school for the Matrics, but soon saw the evidence of the celebrations lying at the entrance to the foyer and paraphernalia dotted around elsewhere!
Last week I attended the launch for the “Post-School Access Map” at the Wits Business School, Johannesburg. The web-based resource that was launched gives information on opportunities and choices for after school, and has been developed by BRIDGE with funding and support from the Zenex Foundation.
I was inspired by how well the launch event was attended, with people from all levels within the education sector and many organisations and schools represented. It was a very focused event, which was great, as one can easily get lost and overwhelmed discussing the myriad of challenges in education, resulting in the discussion being diluted. But, the majority of the discussion was acutely focused on how to enable learners, and their support structures, to identify and pursue opportunities after school.
Sitting at my desk on a Monday morning, my stiff, scratched legs are a reminder of a weekend well spent, full of adventure and exploration!
I don’t often stop to take photos on a trail race, but the unexpected, overwhelming sense of exhilaration I felt as running through the mountains in Mont Rochelle Nature Reserve, forced me to pause, dig my phone out of it’s zip lock bag and try to do the experience justice with my panoramic shots. Either way, that sense of pure, natural, unburdened freedom is still lingering with me into the week.
Today I had the opportunity to go on a excursion to Vusisizwe Secondary School in Worcester, a town about 120 km from Cape Town. The school is one sponsored by Vodacom and as such, they have access to our adaptive, online tool for learning Maths and Science. At Siyavula, we have an in-house team responsible for the “Vodacom project” in terms of managing, training and supporting the schools and teachers who have been sponsored access to Intelligent Practice.
This is my forth post about the Natural Sciences training that we ran last year for subject advisors across the country. You can read more about the project goals and design (part 1), the programme and resources created (part 2) and how we assessed and exposed key misconceptions in the different knowledge areas (part 3).
At Siyavula, we believe in constantly asking for feedback from a group both during and after a workshop. What often comes to my mind when reflecting on feedback are examples from biology where one can get positive feedback loops and negative feedback loops. Both are necessary for a healthy individual or ecosystem. The same is true for any process where you want to constantly be tweaking, making adjustments, finding a balance between different needs and expectations and using the feedback to respond and evolve. Closing these feedback loops is crucial in developing a successful, sustainable, long-term process.
Open communication is also vital to building and maintaining a community of practice. By keeping the lines of communication directly open with your participants, and following up with correspondence, I believe you also help to build relationships which will last beyond the physical interaction at a workshop. This will have a long term benefit in creating a community that is willing to share and learn from each other. Following is a summary of some of the feedback that we received, via email and in the post-workshop survey, and some reflections on the success of the various sessions throughout the workshops. Personally, I also find it a consolidating process to write all of this down, which is why i have written these blog posts, as it allows me to reflect on my own experiences as well.
