Questions

What topics do people talk about in terms of project-based learning (PBL) on Twitter?

Methods

Data Source: The recent 200 tweets that are related to PBL on Twitter using Twitter API. (Reduced number of tweets from 5,000 to 200 due to the limited memory)

Data Processing: Tokenized, stemming, tidied text, and Latent Dirichlet allocation (LDA).

Data Analysis: Word Counts, Term Frequency, Document-topic Probabilities, Griffiths2004 Metrics

Conclusion

By comparing and contrasting the extracted topics using the stm, lda, and gamma function, following themes seem to emerge: 1. What PBL is about and can bring about Project-based learning is a pedagogy endeavors to cultivating deep learning through projects. For example, terms such as “question,” “opportunities,” “share,” and “inquiry” in Topics 1, 2, 9 in LDA modeling and “research,” “explor,” “engag,” and “curriculum” in Topics 3, 4, 6 in stm/gamma modeling.
2. In what domains PBL is deployed Topics 5, 7, 8 in LDA modeling and topics 1, 9 in stm/gamma lay out the domains covering linguistic, science, math, etc.
3. Who is involved in PBL It is suggested that a wide range of parties are involved in the talk of PBL. Particularly, topic 10 in LDA modeling and Topics 2 & 13 in stm/gamma modeling showed that schools, tech organizations, and educational consulting corporations are all involved. Besides, it is worth noticing that PBL topics are mostly about k-12 education.

Discussion

  • Limitations: As the “findThoughts” function failed in the last section, the concluded themes would need further investigation.
  • Implications: Project-based learning as a student-centered pedagogy has not only received broad attention in different domain areas but also involved wide stakeholders in contributing to its development.
  • Next Steps for Analysis: Further studies using survey and interview engaging different participant subjects (e.g., teachers, students, coaches, administrators, principals, parents, etc) are particularly needed to expand our understanding about public opinions toward PBL.
