Welcome to our blog. Here you can find updates on new developments, tips & tricks, and guides on how to get started with DataClassroom.
The R Project is fantastic. With it, you can do virtually any data visualization or analysis task - and it is free and open source.
But it’s probably not controversial to say that learning to code in R can be pretty intimidating for many.
Our Bridge to R feature provides scaffolding to give learners a great starting point.
Read MoreThere is a misconception that students should use spreadsheets for everything - because “that’s what they’ll be using when they are in the workplace”.
But scientists don’t generally use spreadsheets for visualization and analysis. And there’s a reason for that.
Read MoreTwo new features we’d like to tell you about today:
Plotting residuals (and slopes) from regression lines
Plotting a reference normal curve on histograms, and testing for normality.
Read MoreSometimes your data need a bit of tweaking. Not to falsify your results (of course!) but maybe they need to be in different units of measurement, or you want to convert a linear measurement into an area.
Read MoreWe just added a whole bunch of new color scales to the app, so you can color-map your graphs with even more color schemes with spicy names like Magma and Viridis…
Read MoreWe’re pleased to announce the launch of our new online User Guide!
And a new feature - the ability to customize which controls appear on the user interface, so the app can appear simpler, or more advanced.
Read MoreIt’s not that all bar graphs are bad. However, when not used carefully, bar graphs have the potential to unnecessarily hinder a student in learning to interpret data through graphs. With data from classroom experiments at the middle or high school level, we often want students to compare averages of some measured variable across groups. What are the best graphing options for this situation?
Read MoreHow can a digital tool support a student as they begin to work with their own data? It’s all very well to just provide the features they’ll need, but what exactly can a tool assist with at the data import and preparation stages?
Read MoreDescriptive statistics, like mean, median and error bars, illustrate specific aspects of data, and are valuable in drawing conclusions or making comparisons.
We have focused on making these easily available, and easy to play with and to switch between the various forms, to encourage the student to think more about which story their data is telling them.
Read MoreMy 10th grade biology students had just completed the classic heart-rate/exercise lab and I was left wondering why it fell so short of the learning experience I had planned for them. Despite the great data that my students collected, I had failed yet again to budget sufficient time to really dive into the data analysis with the class.
Read MoreBy graphing the data in a way that illustrates the question, for example “Are these groups significantly different?”, the student has already done the groundwork.
When they then click on the Graph-Driven Test button, the tool uses this information to suggest an appropriate test.
Read MoreThe Graph Wizard is an optional assistant for students that could use help in choosing and setting up an appropriate graph for their data.
Read MoreWe know that this is an extremely difficult moment in education as we are all scrambling to figure out what learning looks like for students during weeks to months-long Covid-19 school closures. We already offer free 90-day trials of DataClassroom and will extend that for any affected school or family for as long as this thing lasts.
Read MoreAs we teach kids to work with data we believe that it's important to teach best practices that support the learning of a wide range of data skills of increasing complexity. Coding, statistics, and data visualization are all sought after skills in the workplace.
Read MoreWe know that your lessons are continually getting better with each iteration. Your First Period class does not always get the same polished lesson that your Sixth Period class does, because you are always reflecting and trying to get better for your students.
