The document discusses using learning analytics to influence a learning environment. It describes collecting data on learners and their activities, analyzing the data to identify factors that can predict performance, and using those predictions to design interventions aimed at improving learning outcomes. The presentation provides examples of the types of data that could be collected, potential analyses that could be performed to predict exam scores or other metrics, and possible interventions based on those predictions.

Exploring Scores
Step 1: Load both data sets into “data frames”
Step 2: Show a summary of the data just read
Step 3: Histogram of the score_1 column of
scores.csv
Step 4: Evolution of student scores

Exploring Events
Step 5: Add 5 more columns to the event
data-frame. Value “1” if event of certain type.
Step 6: Count the events of each type and
aggregate for each user
Step 7: Merge previous columns with score
factors. The result has 14 factors (9 scores +
5 with number of events).

Exploring data sets
Do you have an idea about the type of facts
collected?
Is there any new information you discovered?

Potential predictions and interventions
Which factor (present or new) would you like
to predict?
What kind of intervention would it prompt?
