Critical Thinking

Topic - Graphing Quadratic Functions. Students were given a solution to a question which had 5 mistakes. Working individually for five minutes students had to identify the errors and correct them. Then working in their groups (3 or 4) they were given a further 10 mins to share their ideas. Then each group was given the opportunity to report to the whole class. All students had a high level of success. Students were asked to mark the solution using blunder and slips as per marking schemes and the majority of students awarded the correct mark. This was a very useful exercise in showing students how to critically examine work in order to achieve a higher grade. Hopefully they will put it into practice!
