The Simple Genius of a Good Graphic

New graphics and data visualizations are emerging every day trying to portray the data and reality that surrounds us. However, like most things in the world, it is the law of Occam's razor that sets the bar. It is a principle of theory construction or evaluation according to which, other things equal, explanations that posit fewer entities, or fewer kinds of entities, are to be preferred to explanations that posit more. Or in other words the simplest solution is usually the best. This is especially true with graphics and data visualizations, a lot of times one can spend endless hours designing a new dashboard that no one is looking at later, simply because it is either too complicated or it's not answering the questions users want to pursue. Whether that is in education or not, we strive to present the information in the simplest way to enable teachers and schools take data-informed actions to ultimately benefit the learners. In this short, 5 min TED talk that is part history lesson, part love letter to graphics, information designer Tommy McCall traces the centuries-long evolution of charts and diagrams, and shows how complex data can be sculpted into beautiful shapes. "Graphics that help us think faster, or see a book's worth of information on a single page, are the key to unlocking new discoveries," McCall says.

Using Social and Emotional Data to Promote a Positive School Culture

I came across this great article on Edutopia by Victoria Curry and Mike Setaro on how school leaders can combine traditional data with social and emotional data to get a full picture of the school experience of students and staff. It’s centered around Warm data that gives both dimension and measure to an individual’s and group’s social and emotional status. Opposite to Cool data points, that are a series of structural data sets such as enrollment, attendance, and academic proficiency that typically are the bedrock of school-based analytics. They talk about various examples of Warm data points among them on a matrix with different degrees of pleasantness and energy before engaging in learning (inspired by Mark Brackett’s work). These points can and should be captured, measured and visualized. The insights from this data should be of utmost importance for leaders to find strategies that capture and leverage information related to SEL and interpersonal skills. Harnessing this level of und...

Atlas Protocol - Looking at data

The Atlas Protocol is one of the most commonly used structured dialogue formats among schools to facilitate a conversation about data for teachers and other members of the faculty. Learning from Data is a tool to guide groups of teachers discovering what students, educators, and the public understands and how they are thinking. The tool, developed by Eric Buchovecky, is based in part on the work of the Leadership for Urban Mathematics Project and of the Assessment Communities of Teachers Project. The tool also draws on the work of Steve Seidel and Evangeline Harris-Stefanakis of Project Zero at Harvard University. The protocol gives a detailed step by step guide on how to prepare and conduct a healthy, productive conversation about and with use of data. It starts with a selection of datasets that do not lead to a single conclusion and generally lead to rich conversations. From that point forward, the protocol describes 6 stages the group has to follow with the help of a facilitator in...

What Data Can’t Do

I came across this fascinating article from the The New Yorker that really speaks volumes about how careful we have to be when it comes to using and visualizing data. Whenever you try to force the real world to do something that can be counted, unintended consequences abound. The COVID pandemic demonstrated just how vulnerable the world can be when you don’t have good statistics, and the US Presidential election filled our newspapers with polls and projections, all meant to slake our thirst for insight. The same applies to education where knowing what to measure, but also why you want to measure it, is the primary hurdle to tackle. We all have a tendency to naturally trust data as it aims to represent something we are observing. However there are times when simply even solid data is not enough for decision making. That’s why the context, the aim, and the balance between quantitative and qualitative data is so important. As the article states: “The great psychologist Daniel Kahneman, w...
