Abstract

A learning management system (LMS) data portal contains data collected as a byproduct of the running of the LMS. A data dictionary related to that data portal contains both critical information about the data and a list of terms and definitions describing the data contents. The modern LMS studied here has multiple channels for data capture and analytics: (1) the front-facing LMS (at both the instructor level and the admin level), (2) the reports feature (for system administrators), and (3) the data portal (for system administrators). This chapter describes some ways to understand data possibilities through the examination of an LMS data portal data dictionary and light LMS data exploration.

Introduction

A natural byproduct of learning management systems (LMSes), social media platforms, and most technology systems is data. Every time a person interacts with a computer system, they leave a record of their actions. In systems that enable online learning, this means a wide range of data about actions such as the following result in record creation:

  • A teacher or graduate teaching assistant drafts an assessment.

  • A learner logs in for the first time, navigates over to the discussion board, posts a message to several co-learners, downloads a slideshow, and then logs off.

  • A team uploads a consensus-built learning rubric that is designed with a range of learning outcomes and shared across a department or college or university.

  • A gradebook is downloaded, grades adjusted, and re-uploaded.

  • An instructional designer uploads a digital learning object (DLO) linked to a cloud service that collects data about the learning.

  • A classroom of 250 students logs in and takes a proctored online exam with security features to prevent academic dishonesty.

  • After a field trip, learners upload dozens of images depicting their experiences.

  • After a semester, an online course is archived off-line and taken off web servers.

And so on. More simply, every command created by people result in a record. And if the technology system has integrations with other technology systems, every interaction between those systems will result in records as well. For every action and transaction taken by users in a system, there is captured information, to enable the technology systems to function. Oftentimes, this data remains on the back end and does not attract much attention.

In recent years, the data that is a byproduct of the functioning of learning management systems (LMSes), technological tools that enable distance or distributed (and blended / hybrid, and F2F) learning, has come to the fore. Much of this data has been made available to enable users to better understand the system and how people are using it, as well as considering ways to improve teaching and learning through it. In 2016, Instructure made much of its back-end data available (by instance) on an LMS data portal, and later that year, Kansas State University (K-State) requested access to their data portal and started some informal exploration of what was available. An LMS data portal is a website where selected data from the LMS instance may be accessed. The data types are common ones, including time data, integers, big integers, Booleans (true/false), floating point numbers, alphanumeric strings (as text labels, as text fields), and others.

An initial study of the data from their LMS instance was conducted, and the results of this were broadly published (Hai-Jew, Spring-Summer 2017). Over time, it became clear that there were three main channels for access to large-scale LMS data, through administrator access: the front-end of the LMS, the reports section of the LMS, and the LMS data portal (Table 1). In terms of the front-end of the LMS, there are other role-based accesses, including for librarians, graders (graduate teaching assistants), guests, instructional designers, and others, but their levels of access are lower than for instructors. Different institutions can set up their roles and role-based accesses in a variety of ways and with different term labels.

Key Terms in this Chapter

Big Data: A relatively large amount of data, defined sometimes as over a million rows of data or a certain size of data (such as by terabytes and petabytes).

Data Portal: An online space through which data tables (often compressed) may be accessed.

Structured Data: Labeled data in data tables.

Data Dictionary (or Data Schema): A compilation of terms and definitions about the data available in complex datasets.

Learning Management System (LMS): An online system that enables various capabilities for learning: learner registration, persistent learner accounts, profile-making, content delivery and sharing, intercommunications, collaboration, assessment, learner verification, and others.

Online Learning: The use of communications technologies for distributed learning.

Unstructured Data: Imagery, videos, simulations, and other types of unlabeled data.

Data Mining: Identification of patterns in data in the pursuit of information and insights.

Digital Learning Object (DLO): A unit of learning expressed in digital contents.

Semi-Structured Data: A mix of labeled and unlabeled data (such as a data table with imagery involved).

Blended Learning (Hybrid Learning): A combination of F2F (face-to-face) and online learning, combining the real-space and the virtual.

Data Table: Structured data comprised of variables in the columns and records in the rows.

Data Query: Conducting structured questions about data.

F2F: Face-to-face.

Computational Linguistic Analysis: The use of computers to analyze language features in curated text sets through autocoding (including sentiment analysis, theme extraction, language feature counts, psychological metrics, and others).

Text Mining: The exploration of data patterns from text sets (curated and uncurated).

Data Dashboard: A web page or multiple linked web pages with interactive data visualizations representing related constructs.

Flat File: A stand-alone data table without relations defined in connections to other flat files.
