1. Information for teachers This PowerPoint presentation gives examples of the types of questions that your students may write. They can be used to discuss the structure of a good question or fixing up a question that is not quite right. Feedback of a general nature is given when the question needs improving (as might be done in an assessment) by circling the part of the criteria that has not been met. This PowerPoint is editable so can be changed to suit the wording you choose to use with your class or specific examples from your students. www.education.nzta.govt.nz

3. A suitable comparison investigative question is one that reflects the population, has a clear variable to investigate, compares the values of a continuous variable across different categories, and can be answered with the data. Do students in the Year 11 class surveyed at Te Horo HS in 2014 tend to have a high accuracy (%) if they are not tired compared to students in the Year 11 class surveyed at Te Horo HS in 2014 that are tired.

A suitable comparison investigative question is one that reflects the population, has a clear variable to investigate, compares the values of a continuous variable across different categories, and can be answered with the data. Do students from Te Horo HS in 2014 who are texting tend to have faster reaction times than students that were not texting. Question is fine. It might be clearer to have ‘Te Horo HS in 2014’ repeated again towards the end of the sentence but this question is fine

Do tired students tend to have faster reaction times than not tired students in 2014?

11. A suitable comparison investigative question is one that reflects the population, has a clear variable to investigate, compares the values of a continuous variable across different categories, and can be answered with the data. Do students at Te Horo HS in 2014 with low typing accuracies tend to have higher typing speeds than the typing speeds of those students at Te Horo HS in 2014 with high typing accuracies?

12. A suitable comparison investigative question is one that reflects the population, has a clear variable to investigate, compares the values of a continuous variable across different categories, and can be answered with the data. Do Year 11 students at Te Horo HS in 2014 tend to have faster (shorter) reaction times than those of Year 10 students at Te Horo HS in 2014?
