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, document-term matrix.

Data Analysis: Word counts, term frequency, tf-idf, document-topic Probabilities, structural topic model (STM), Latent Dirichlet allocation (LDA), correlation (phi-coefficient).

“Teachers! If you are keen to incorporate project-based learning into your #STEM lessons, but don’t know where to start, #CREST has some fantastic resources for you!Why not check out our secondary starter guide here.”

“Yes, let’s integrate news into the day on a regular base. Also, connecting to experts as often as possible.”

“Retweet this post and tell me why you want a copy of the book Project-Based Learning. I will select a winner and ship a copy out. Thanks.”

“Do your students ever ask you: ‘When am I ever going to need this?’ If they do, consider rigorous #PBL units in middle and high school math as your answer to that age-old student question.”

“I’d like to listen, I truly believe we need project based learning, maker cultures and circular/civic economics at the earliest age, through fun and play. Not for ‘jobs’ market reasons, but to normalise fun/creativity/context/purpose as everyday not ‘special’ or siloed.”

“LoveLD - love this myth-busting post about Project Based Learning.”

“Exactly! That budget would fund maybe 350 schools to engage local digital film companies to produce their own consent ads.. project based learning, content and stimluate local arts!Fkkrs. #milkshakevideo sucks.”

“Wildcatters combined two preexisting technologies to revolutionize the global energy. Delightfully this reduced coal use and dependence on corrupt regimes. Will we see a revolutionary combo to help K-12 recover from the COVID catastrophe?”

“I would argue that fake news is not any more prevalent than in the ‘olden days,’ it just distributes faster and I feel like people are less discerning in their critical analysis.”

• Q1: What do people say about project-based learning (PBL) on Twitter?
  • People are using Twitter to share resources and call on participation related to PBL.

• Q2: What key topics do people talk about PBL on Twitter?
  • Topic 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.
  • Topic 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.
  • Topic 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.

• Q3: In general, what do Twitter users feel about PBL?
  • Generally speaking, most people on Twitter are feeling positive about PBl, believing PBL can bring both ‘rigor’ and ‘fun’ in learning.

• Q4: What are the relationships between words (bigram) of PBL tweets?
  • ‘adminchat,’ ‘cpchat,’‘mathchat,’‘suptchat,’ ‘elemchat’ seem to be the groups that involve most of PBL discussants on professional development and support.
  • PBL seem to be related to the AP classes of students who are from low-income families (aka inequity).

• Limitations
  • Due to the limited memory of the author’s laptop, the data frame of this study is rather small (n=200), and therefore might not catch some features of people’s opinion about PBL on Twitter.
  • The findings only depict a brief picture of the phenomenon, further studies are needed to grasp deeper information out of it.
• 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 of public opinions toward PBL.
