Journal retracting at least nine articles by education researcher

without comments

JAASEPA investigation in Singapore has failed to turn up primary data that formed the basis for 11 papers from one author about special education.

In addition, a forensic investigation at Noel Chia’s institution — the National Institute of Education in Singapore, part of Nanyang Technological University (NTU) — suggested that some signatures providing parental consent might not be authentic. The investigation was also unable to authenticate the Malaysia-based organization Chia said collected the data on his behalf.

Nine of the papers appear in the Journal of the American Academy of Special Education Professionals (JAASEP), which has declared it plans to retract every article Chia has ever published with them (we’ve counted an additional nine papers).

Much of the information we know about the case stems from the unusually detailed — 3,000 word — retraction notice from JAASEP:

Who has the most retractions? Here’s our unofficial list (see notes on methodology), which we’ll update as more information comes to light:

  23. Fazlul Sarkar (18)
  24. John Darsee (17)
  25. Wataru Matsuyama (17)
  26. Alirio Melendez (17)
  27. Robert Slutsky (17)
  28. Ulrich Lichtenthaler (16)
  29. Erin Potts-Kant (16)
  30. Stanley Rapoport (16)

We note that all but one of the top 30 are men, which agrees with the general findings of a 2013 paper suggesting that men are more likely to commit fraud.

Notes:

Many accounts of the John Darsee story cite 80-plus retractions, which would place him third on the list, but Web of Science only lists 17, three of which are categorized as corrections. That’s not the only discrepancy. For example, Fujii has 138 retractions listed in Web of Science, compared to 183 as recommended by a university committee, while Reuben has 25, compared to the 22 named in this paper. We know that not everything ends up in Web of Science — Chen, for example, isn’t there at all — so we’ve used our judgment based on covering these cases to arrive at the highest numbers we could verify.

Shigeaki Kato is likely to end up with 43 retractions, based on the results of a university investigation.

All of this is a good reminder why the database we’re building with the generous support of the MacArthur Foundation and Arnold Foundation will be useful.

Journal retracts all papers by education researcher, bringing his total to 21

with one comment

jaasepA journal has followed through on its promise to retract all articles by an education researcher, after an investigation raised questions about the validity of the data in some of his work with children with special needs.

The latest notice — which includes a list of 11 papers — brings the total number of retractions for Noel Kok Hwee Chia to 21.

Last spring, The Journal of the American Academy of Special Education Professionals (JAASEP) pulled nine articles by Chia that were the subject of an investigation at the National Institute of Education in Singapore, part of Nanyang Technological University, where he worked until April. As we reported in June, editors explained in a 3,000-word notice that they planned to pull every article that Chia had published in JAASEP.

The new retraction notice quotes from the reasoning presented in the previous one, from last spring:
