A week in replication, some failed, some successful: Big Five, note taking and stereotype threats

From experience to meaning...

The past week I read several replication studies with mixed results:

First, although direct replications (using methods from Mueller and Oppenheimer 2014) yielded longhand-superiority effects, the effects relevant to the encoding function of note-taking were small and did not reach conventional levels of significance. Such outcomes do not support strong recommendations about whether students should take notes longhand or by laptop in class. Second, based on their evidence, Mueller and Oppenheimer (2014) hypothesized that the higher word count and verbatim overlap for laptop groups were in part responsible for diminished performance…

The Butterfly Who Denied Ever Being a Caterpillar: A Modern Day Educational Fable

3-Star learning experiences

Paul A. Kirschner & Mirjam Neelen

Did you hear the story about the butterfly who denied ever being a caterpillar? Well, there was once a beautiful, well-developed butterfly who refused to accept that he once was a caterpillar and that going through the stages from pupa to caterpillar to beautiful butterfly was responsible for his current state…

Almost weekly, we encounter (or are asked to comment on) some new, modern, progressive, child friendly, innovative approach to education. Usually, advocates for these approaches have a strong distaste for knowledge acquisition, fact learning, memorisation, and practising skills such as addition, subtraction, multiplication, spelling, handwriting or writing essays (Who needs all of these things in real life? We have pocket computers for this, and, who writes essays these days?). They find these things to be old-fashioned, demotivating, and extremely mind-numbing. They believe in the child’s own initiative to drive learning as they perceive…

İyi Kehânet Yapma Rehberi

Yalansavar

Yalansavar olarak bundan böyle her sene yapmayı düşündüğümüz bir podcast kaydı gerçekleştirip yayımladık geçen hafta: 2018 Kehanetleri…

Bu kayıtta 2017’nin sonunda TV’lerde veya gazete röportajlarında medyumluk güçlerine veya astroloji bilgilerine dayanarak 2018 hakkında yapılmış bir takım kehanetlerin gerçekleşip gerçekleşmediğine baktık. Sonuç tahmin ettiğiniz gibi fiyasko. Detayları zaten programda dinlersiniz… Benim bu yazıdaki amacım başka: Programda da vadettiğim üzere “kehanet yapmak isteyen gençler” için bir kılavuz hazırladım. Gözünüz korkmasın. Aslında çok kolay! Siz de tutma olasılığı yüksek kehanetlerde bulunabilirsiniz 🙂 Aşağıdaki kontrol listesine uysun yeter!

NE: Konu seçimi

İyi ve tutma olasılığı yüksek bir kehanette bulunmak istiyorsanız, konu seçimi çok önemlidir. Konunuz mümkün olduğunca çok sayıda insanı ilgilendirmeli. Örneğin önümüzdeki yıl nalburiye satışlarındaki değişim hakkında bir kehanette bulunursanız hitap ettiği kitle çok dar kalır. Kehanet yapmaya değmeyecek bir konu olur bu. Bu sebeple biraz daha makro ölçekli konular ele alınmalıdır. Şüphesiz bu konular:

  • Doğal afetler (deprem, sel, taşkın, küresel ısınma, iklim…

Can you train executive functions? A second meta-analysis says…

From experience to meaning...

In 2015 I wrote this blogpost on a meta-analysis on the training of executive functions. The results were a bit depressing. Today I found a new meta-analysis via Jeroen Jansen and the results… are again not that good and it all has to do with one of the key concepts in education: transfer.  The meta-analysis was based on 38 studies with 47 contrasts.

I’ll first share with you the abstract of the study:

In the present meta-analysis we examined the near- and far-transfer effects of training components of children’s executive functions skills: working memory, inhibitory control, and cognitive flexibility. We found a significant near-transfer effect (g+ = 0.44, k = 43, p < .001) showing that the interventions in the primary studies were successful in training the targeted components. However, we found no convincing evidence of far-transfer (g+ = 0.11, k = 17, p = .11). That…

Qualitative study: how managerialism in UK schools erodes teachers’ mental health and well-being

From experience to meaning...

I have been a full day at a very interesting conference about data and educational policy, but than you read this study and you remember some of the teachers you know who had a burnout lately. There are always real people behind the data! This study is a qualitative study in which the researchers try to understand what can worsen mental health and well-being of teachers.

From the press release:

Performance targets, increased workload, curriculum changes and other bureaucratic changes are eroding teachers’ professional identity and harming their mental health, a new study in Educational Review finds.

The study’s authors interviewed 39 teachers across England and Wales who had experienced long term absence from work due to mental health problems, and six head, deputy and assistant head teachers who had dealt with mental health problems among staff.

The teachers cited constant, complex change in educational policies, target-led performance, lack…
