Predict, Observe, Explain (POE) in a Nutshell
Predict, Observe, Explain, (POE). is exactly what you would expect. Basically, students make predictions about what will happen in an experiment, observe the experiment, and then explain what happened and why. This is especially effective with science demonstrations. For example, if I want to mix baking soda and vinegar together in a demo, I would ask the students, "What do you think will happen when I mix these together?" Students would then take a few minutes to write down their predictions. Once everyone has had a chance to predict, discussion can take place where students explain their predictions and their rationale for them. This can uncover common misconceptions and help teachers direct their questioning appropriately. Next the teacher conducts the experiment and students observe. Students can record observations and then think about why the experiment produced certain results. Finally, students try to come up with their own scientific explanations. Teachers can then interject where necessary to make sure students have the correct scientific explanation.
In today's classrooms, we don't always have the time or materials for all students to be conducting experiments. This is a great alternative to make sure they are getting exposed to key scientific concepts. Predict, Observe, Explain also gives students the opportunities to engage in scientific practices such as engaging in argument, or drawing conclusions.
One of my more recent creations is a set of 10 demonstrations with Predict, Observe, Explain sheets for each one. Give them a try; you won't regret it!
Great mnemonic. Kids will really remember and apply it when completing experiments!
ReplyDeleteI have used POE with my students when we do science experiments. I have found it very useful. I agree with XClass, it is a great mnemonic. Often you see some humorous predictions!
