The Metacheck Shiny app to download all private OSF Repositories is done. The manual is updated, everything is in the dev branch on GitHub. We explain how you can run repo_check, data_check, code_check, and codebook_check on your repository with 1 line of code. Launch next week.

A wonderful event for ECRs doing meta-science.
I'll give a workshop on "How to use AI tools, agents, LLMs, and automation to improve open science practices"
Hope to see you there.

The Montessori method shows clear potential, but the evidence base is surprisingly fragile. A new meta-analysis reveals that large reported learning gains are heavily undermined by publication bias, weak experimental controls, and a failure to track implementation fidelity.

We launched our beta version 0.0.1 of Metacheck today! After our second year of work on the tool, we now have validated modules, hugely expanded functionality, optional (or local) LLM use, checks inside code files, and much more! Try it out in R now: scienceverse.org/metacheck/

The multilevel extension to RoBMA was just published in BRM. Together with Maximilian Maier and Eric-Jan Wagenmakers, we developed a 3-level version of RoBMA which allows analysts to adjust for publication bias in meta-analyses with estimates nested within studies.
