The above video represents the most recent iteration of my dissertation work; a design-based research project that investigates how learning analytics tools and approaches, applied within the context of a technology-enhanced, blended learning environment, can support a Knowledge Community and Inquiry (KCI) approach to secondary science.  In the video I present the design of CKBiology; a software … Continue reading CKBiology


“Give a colony of garden ants a week and a pile of dirt, and they’ll transform it into an underground edifice about the height of a skyscraper in an ant-scaled city. Without a blueprint or a leader, thousands of insects moving specks of dirt create a complex, sponge-like structure with parallel levels connected by a … Continue reading Eusociality

Exploring Learning Analytics Software: D3.js

From the website: D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG, and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach … Continue reading Exploring Learning Analytics Software: D3.js

Exploring Learning Analytics Software: RapidMiner

I first heard about RapidMiner from the “Data Analytics & Learning” MOOC (Siemens, Gasevic, Baker, and Rosé, 2014). For this evaluation, I installed a trial version of RapidMiner Studio (desktop software version) and performed the introductory tutorials. Like Data Science Studio (DSS), RapidMiner is used for generating predictive models.  However, unlike DSS - which records … Continue reading Exploring Learning Analytics Software: RapidMiner

Exploring Learning Analytics Software: Data Science Studio (DSS)

For the purposes of this exploration, I am using a 14-day free trial version of the cloud version of DSS, which includes several tutorials for new users. DSS enables users to import data from a variety of sources (see Figure 1), however the dataset must be in tabular format - i.e. an SQL Database is … Continue reading Exploring Learning Analytics Software: Data Science Studio (DSS)
