This document discusses using text analysis to enhance conversations between students and teachers. It describes text analysis techniques like word frequency, collocations, and statistical/rule-based approaches. Case studies are presented on using text analysis of student work, discussion posts, and evaluations to provide pedagogical insights. The tool Quantext is introduced, which analyzes short student texts to evaluate understanding over time and extract insights. Partnerships are encouraged to further develop these applications of text analysis for teaching and learning.

29. What is Quantext
A text analytic tool designed to
foreground the fragile interplay
between student and teacherâŠ

https://github.com/quantext/quantext
31. What is Quantext?
A work in progress:
Explore short-form student text from any source âŠ
Evaluate text at scale, over time and in real-time
Extract pedagogic insights
Explore the interplay between student and teacher
33. Case study: Undergraduate teaching
Identify student conceptions
Inspect top keywords, entities or themes in student work
Explore keywords etc. in context
Compare with teaching materials
Remediate
37. Case study: MOOC discussion posts
Evaluate posts
Sort and filter posts by length,
Identify common content words and word groups
Relate comments to participation
Relate discussion points to interests?
38. Results (RQ1)
Points of interest identified in the
analysis of introductory discussion posts
âąclimate change - third most frequently-
used bigram
âągeology â in the first 20 most frequently-
used words
âąearth science/s and interest in geology -
other frequently-used language chunks
âąless so in history (about 11% of the
students mentioned history)
41. Case study: Student evaluations of teaching
Explore student perceptions of SET
Sort and filter responses by length,
Identify common terms from keywords, ngrams, entities
Identify common themes from random sample
Do common terms reflect themes?
Automatic classification of responses into themes?
42. Case study: Student evaluations of teaching

47. Case study: Student evaluations of teaching
ââŠif we are going to ask students to take the time to respond to open
questions, we owe it to them to take the time to analyse their
responses. âŠeven for large classes and student cohorts, advances in
text analytics make this quite feasible.â
