Harnessing the Power of Big Data (FETC 2015)

Teachers and school administrators at all levels are inundated with data, at times so large and complex that it becomes difficult to process. Explore opportunities and approaches with Tableau, a data visualization application, that information technology services has utilized at Loyola University Chicago for data-based decision making. This includes connecting to multiple databases, Excel spreadsheets and commingling other data types to visualize and inform decision making. Participants will experience hands-on application of using “big data” sets with Tableau Public, as well as best practices for handling large data sets and how to construct reports/dashboards with the tool.

    Level One HOW “BIG” IS BIG DATA?
  12. Final Cut Pro 7, Level One Final Cut Pro X,

    Level One What is big data? Big data can be described as… • All-encompassing term for any collection of data sets; • Large/complex that it is difficult to process them using traditional data processing applications. • Challenges include analysis, capture, curation, search, sharing, storage, transfer, visualization, and privacy violations.

    Level One http://i.huffpost.com/gen/857744/thumbs/o-PINOCCHIO-facebook.jpg INFORMATION, DATA AND CONTEXT DO THEY INDIVIDUALLY LIE TO US?
  14. Final Cut Pro 7, Level One Final Cut Pro X,

    Level One Test scores static for Illinois students
 Malone, T. (2009, October 15). Test scores static for Illinois students. Chicago Tribune.
 Illinois schoolchildren flat-lined on a national math exam last spring and showed little improvement during the last two years in narrowing the achievement gap that divides minority and low-income students from their peers, according to a report released Wednesday. The state results mirror the trend seen elsewhere in the country on the National Assessment of Educational Progress. "Illinois is holding steady, and the nation is holding steady," said spokeswoman Mary Fergus with the Illinois State Board of Education. Is this the full picture? What’s missing? What may account
 for “flat-lined” performance by students? What questions would you ask the writer?

    Level One Magnitude
 The Lie Factor The standard required an increase in mileage from 18 to 27.5, an increase of 53%. The magnitude of increase shown in the graph is 783%, for a whopping lie factor = (783/53) = 14.8! http://www.datavis.ca/gallery/goosed-up.php
  16. Final Cut Pro 7, Level One Final Cut Pro X,

    Level One Variation
 The Lie Factor Another key element in making informative graphs is to avoid confounding design variation with data variation. This means that changes in the scale of the graphic should always correspond to changes in the data being represented. This graph violates that principle by using area to show one-dimensional data, giving a lie factor = 2.8. http://www.datavis.ca/gallery/goosed-up.php
  17. Final Cut Pro 7, Level One Final Cut Pro X,

    Level One Changing Scales
 The Lie Factor A less obvious way to create a false impression is to change scales part way through an axis. This graph, originally from the Washington Post purports to compare the income of doctors to other professionals from 1939— 1976. http://www.datavis.ca/gallery/goosed-up.php

  35. Final Cut Pro 7, Level One Final Cut Pro X,

    Level One Education and Big Data Opportunities Pre-Class, In Class and Post-Class Expanding Data and Information • Collaborating with other institutions or schools including government agencies. Government agencies can be a key to obtaining additional contextual data. • Harvesting non-structured data from major student gathering places such as Facebook, usage patterns from apps, and download patterns from various app stores. • Introducing new types of data, including voice capture and facial expression data (from webcams/microphones). http://www.gartner.com/document/2112515
  36. Final Cut Pro 7, Level One Final Cut Pro X,

    Level One Education and Big Data Recommendations Pre-Class, In Class and Post-Class • Learn from big data in research - leverage skill that is developed; • Use big data only where there is a chance to discover correlations; • For adaptive learning, collect and correlate data only when there is enough variation in the learning modes examined to provide information that can lead to pedagogical variation. • Make sure to pose a big data question so that the advice gained from it is actionable, for both institutions and individuals; • Big data requires "big thinking," so challenge conventional wisdom. • Take what everyone else sees, and think beyond the obvious. http://www.gartner.com/document/2112515

    Level One Data Quality • Entry quality: Did the information enter the system correctly at the origin? • Process quality: Was the integrity of the information maintained during processing through the system? • Identification quality: Are two similar objects identified correctly to be the same or different? • Integration quality: Is all the known information about an object integrated to the point of providing an accurate representation of the object? • Usage quality: Is the information used and interpreted correctly at the point of access? • Aging quality: Has enough time passed that the validity of the information can no longer be trusted? • Organizational quality: Can the same information be reconciled between two systems based on the way the organization constructs and views the data?
