The Intensive Partnerships for Effective Teaching initiative enhanced how teachers are evaluated and improved teacher staffing policies but did not lead to gains in student achievement or graduation rates.
PsychBriefLarge-scale implementation of teacher observation designed to improve teaching effectiveness found no effect on student's achievement or graduation rates
PsychBriefPreregistered preprint summarising evidence for the preventative effect of education on cognitive decline due to aging. A lot of heterogeneity but the current evidence doesn't support any protective value osf.io/4mf9z/ By Seblova, Berggren, @MartinLovden
My methods blogs feed was the subject of a recent paper 'Who Posts What about Whom, with What Effect?'. I analyse the paper and provide some context
PsychBriefThere have been quite a few hot takes on the 'who/what do psychology blogs talk about'. If you've not already moved on, I've written some thoughts about it as well as the discussion(s) I've had with lead author Nicolas and senior author Susan Fiske
A couple of years ago, psychologist Susan Fiske launched a broadside against science bloggers – since taken offline – packed with name-calling. That launched a spate of blogging, musing on what it meant to call us and our ilk destructo-critics,...
PsychBriefWhen universities moved towards an incentive system based on quantitative measures, it was intended to improve them. But in reality it has created perverse incentives which favour quantity over quality and worsened conditions for workers
Would that reported effect size lead to the downfall of human civilization if transferred to the real world?
PsychBriefNice blog post putting effect sizes found in psychological research in context: willgervais.com/blog/2019/6/7/… by @wgervais. If the effect size you report would likely have enormous real-world consequences if it were true (i.e. greatly impacting human behaviour), then maybe think again
Making your data anonymous is an important part of ethical scientific practice. I've collected some of the R packages which allow you to do this.
PsychBriefData anonymisation is important but can be difficult. In this short blog post, I summarise some of the means of doing so using R, whether anonymised data is truly anonymised, and how to ethically anonymise data
PsychBriefHave you ever read a paper so good it was genuinely shocking? I've had that reading @dingding_peng's paper on causality and how difficult it is. I genuinely gasped/said 'oh my god' aloud a few times. Essential reading
While reviewing papers, I’ve noticed some boilerplate that keeps creeping up in the “Limitations” sections of studies using cross-sectional, observational designs:
“Of course, we are unable to draw causal conclusions...but future studies with...
