Malcolm Knowles (1984) initially developed the theory of andragogy (adult learning) to differentiate between the ways that adults learn compared to children. In adult learning, the learner needs to understand why the content is important, viewing it through a problem-based lens with real world applicability. Learning is motivated primarily by intrinsic values and self-directed autonomy, with each individual bringing their own previous experiences to the learning environment (Knowles, 2020).
In the BOPPPS model, the Bridge and Summary sections are used to provide a narrative story surrounding the learning content, with information designed to motivate adult learners. The Bridge occurs at the start of a lesson and the Summary occurs at the end.
“A good bridge-in builds on students’ prior knowledge or life experiences and motivates them to learn by setting up problematic situations or describing the value of learning and focusing on what will happen in the classroom.” (Zheng, 2023., p. 36)
In essence, the Bridge either directly shares, or helps students reflect on, the ‘why’ behind the content they are about to learn. It is a short introduction to the lesson. See below for some examples of how a bridge can be created.
“Summary serves as the reflective phase, where key concepts are reinforced, and students are encouraged to consolidate their understanding. This step ensures the long-term retention of knowledge and skills.” (Zhang & Muszali, 2025, p. 48)
The summary is an opportunity to remind learners of the key takeaways of the lesson and ensure they understand what they should now know, be able to do, or value. It should also connect back to the learners’ motivations for learning the content. Some examples of how a summary can be created include:
Ideally, your lesson summary should connect to the original bridge and reinforce the narrative and learning outcomes of the lesson. You may also consider using the summary to lead into the bridge for the next portion of your class or the next lesson in your overall course.
Return to your BOPPPS template and complete the Bridge and Summary sections. Reflect on the narrative you want to provide for your students to help them understand the importance and application of your lesson content. Consider the following questions:
Once you complete this final activity, you will have successfully completed your one-page lesson plan using the BOPPPS structure.
