This week, we’ve spent our time examining a set of research designs – experimental, quasi-experimental, and non-experimental designs – that allow us to investigate the relationships between things. Key among those relationships are causal relationships– relationships in which change in some independent variable causes change in a dependent variable. For schools and practitioners, this question – whether or not something we do causes change in an outcome we care about – is of critical importance.

For your exit ticket this week, summarize and explain, in 3-4 paragraphs, the extent to which each of the designs we’ve talked about – experimental, quasi-experimental, and non-experimental – allow us to make claims about cause and effect. As you do so, be sure to draw upon and reference our class readings and resources.
