If you have ever wondered what goes on to make an effective teacher, this research paper by Angela Duckworth and colleagues, throws some light on the issue.

English: LaPlace, La., October 8, 2005 – Dan Waldman (left), left without a job as a high school teacher at Signature Centers High School in New Orleans when it was flooded by Hurricane Katrina, has been hired by FEMA and is now at the LaPlace Disaster Recovery Center, 160 Belle Terre, and is in training to become a DRC manager. He is a member of the “Teach For America” program that places new teachers into inner city and low-income area schools around the nation. Win Henderson / FEMA (Photo credit: Wikipedia)

  1. Teaching is a stressful job; in majority of cases, you are not able to see the impact of your work immediately or at all; hence the frequent teacher burnout or high attrition.
  2. Traditionally its thought that competence in subject matter or certifications would be a good predictor of teacher effectiveness. However , these measures typically fail to distinguish those performing well from those performing just bare minimal.
  3. When one looks at other factors like personality factors, extarverted or ‘attractive’ teachers get better ratings from students/ observers; however they don’t have any real impact on actual student performance when measured by gains in knowledge.
  4. This study looked at grit, life satisfaction and optimism of teachers as predictors of their effectiveness which will distinguish high performing teachers from the mediocre.
  5. They conducted a prospective longitudinal study wherein, grit, life satisfaction and optimistic explanatory style of novice Teach for America teachers was measured before they started school year. The gains in academic performance of the students they taught was used as an indicator of their effectiveness at the school year end.
  6. Grit, the ability to work hard under challenging circumstances, may be relevant to teacher effectiveness as they do face constant challenges, and so this was measured using the 8 item short Grit scale.
  7. Happy people do well in a number of different work settings as those who are in a positive mood are more likely to work towards their goals;  also they have  more resources to cope with stress and challenges, as per broaden and build theory of positive emotions. Also, the energy and enthusiasm of those teachers satisfied with life may be contagious and make students happy and thus more productive. Life satisfaction was measured by Satisfaction with Life Scale.
  8. Optimistic explanatory style may be relevant as when faced with repeated challenges those with pessimistic explanatory style may become helpless and give up, as compared to those with optimistic style who may remain resilient.  This was measured using Attributional Style Questionnaire.
  9. All three positive traits predicted teacher effectiveness.  When all were simultaneously used to predict the teacher effectiveness outcome, only grit and life satisfaction were significant predictors. It thus seems that optimism works via grit and life satisfaction.
  10. As this is a prospective longitudinal study the results do hint at causality, though reverse causality like effectiveness leading to life satisfaction cannot be ruled out.
  11. The authors conclude by suggesting that schools should perhaps hire for grit, happiness and optimism too. This is where I get a little uncomfortable; in an ideal world, I would welcome anyone who has a passion for teaching (the passion part of grit is taken care of 🙂 ) and equip them with tools like training to increase perseverance, hope and happiness to make them more effective. I am always ambivalent about measuring a trait and then hiring for it. To be fair the authors also suggest interventions in schools to increase grit , hope etc of teachers. I wish there was more of latter than former in the world that we live in.
