How are you Mr Robin McTaggart? My really hope you always healthy and God gives you happiness. I am really glad having you here. Thank you very much for your help a few couple months ago when I asked you about who should do ‘validation’ in classroom action research. And now, if you don’t mind, I am going to ask you about ‘triangulation’ in classroom action research. Could you give me an example about triangulation? Next, I am still confuse about ‘the hypothesis of action.’ Should the hypothesis of action must always be present in CAR? And, what’s parametres should I use to judge whether the hypothesis has been reached or not?

Warmest Regards

McTaggart’s Answer:

Greetings Mutadi,

Triangulation means comparing information from 1. different observation strategies and/or 2. different informants and/or 3. theoretical perspectives:


1. Different sources: a teacher might count the number of times students boys spoke in a classroom using an informal check-sheet, a survey asking each student, or video-recording a class for a time and then observing what the students were doing.

2. Different informants: a teacher might ask boys, girls and the brightest students what percentage of the teachers’ time they attracted.

3. Different theories:  a teacher might use feminist theory to understand any differences from different kinds of data collecting, time management theory to better understand how to use his/her time more wisely in class; or theory of activity based learning to change the kinds of questions he/she asks in class so that students spend more time answering their own questions.

I hope this helps Mutadi.

‘Hypothesis of action’ would mean a statement about what planned action was intended in the situation and what its intended outcomes were. Observation of the plan in action would mean collecting data

about what the teacher did,
how the students responded and
how any other aspect of the situation itself changed.

Best wishes, Robin
