Inquiry through PEOE approach with Authentic Assessment

Inquiry using PEOE approach with Authentic Assessment in Teaching Life Sciences

The PEOE method (Predict explain observe explain) is an inquiry approach that stimulates students to think and investigate phenomenon taking place in the natural environment. It is also an effective approach because it could address possible misconceptions the teacher may not expect from their students. Although the more popular approach is the POE approach (Predict Observe Explain), the PEOE has also been used by some schools that endorse the use of inquiry based science education. Here the focus is on how stems grow tall as the ribbon is tied to the upper part of the shoot or stem of the oregano plant. The students will draw how the plant will look like and where the ribbon will be after several weeks. They will observe how the plant will grow and then evaluate whether their predictions are correct or not. From then, they can conclude that when stems grow tall growth starts at the top and not at the bottom which explains why the ribbon did not go up as the plants grows taller.

Two activities are given. The first option is for teachers who have problems with their budget of work so pictures are just needed for them to work on the concept. The second one (which is highly recommendable), is activity-oriented and will make the students more observant as they will observe week by week the oregano plant until they will discover that growth starts from the top (where the apical meristems are) and not on the bottom. I do hope both teachers can try both strategies and come up with a comparison about the learning outcomes of the students. The Surrey School District in British Columbia also endorses this approach as they have also sample worksheets in their websites.

Take note that this lesson also endorses the use of rubrics which is a form of authentic assessment. We do hope that teachers also use this type of assessment to be able to discover how students think and how the lesson can be further modified for a more student-centered approach in teaching science.
