Many teachers believe they are encouraging students to use meta-cognition when they are just asking students to use strategies – strategies such as making connections when reading or self-verbalising when solving problems. Don’t get me wrong, as I stated in the above point, encouraging students to adopt strategies is important, but it is not meta-cognition. Meta-cognition involves thinking about your options, your choices and your results – and it has an even larger effect on student results than teaching strategies. When using meta-cognition your students may think about what strategies they could use before choosing one, and they may think about how effective their choice was (after reflecting on their success or lack thereof) before continuing with or changing their chosen strategy.
