Evaluation of the SOLO-BOPPPS Instructional Model for Improving Pharmacy Students’ Classroom Engagement and Learning Outcomes: A Prospective Single-Group Crossover Study
This prospective single-group crossover study demonstrates that integrating the SOLO taxonomy into the BOPPPS instructional model significantly improves pharmacy students' classroom engagement, academic performance, and self-efficacy compared to traditional lecture-based instruction.

Imagine a classroom full of pharmacy students trying to learn Physiology—the complex study of how the human body works. It's a subject full of intricate systems, like a massive, tangled web of gears and pipes. For many students, especially those who didn't take biology in high school, this web can feel overwhelming, like trying to assemble a 1,000-piece puzzle without the picture on the box.
Traditionally, teachers have used a method called Lecture-Based Instruction (LBI). Think of this as a teacher standing at the front, pouring information into the students' heads like water from a hose. While efficient, it often leaves students passive, staring blankly, or checking their phones because they can't keep up with the flood of data.
To fix this, educators often use a popular teaching recipe called BOPPPS. Imagine BOPPPS as a six-step cooking guide:
- Bridge-in: A tasty appetizer to get everyone hungry for the lesson.
- Objective: Telling everyone exactly what the meal will be.
- Pre-assessment: Checking if anyone has dietary restrictions (what they already know).
- Participatory Learning: The main course where everyone cooks together.
- Post-assessment: A taste test to see if the meal was good.
- Summary: Cleaning up and reviewing the recipe.
The Problem: Even with this six-step recipe, some students still get lost in the kitchen. The "Participatory Learning" part often fails because students have different starting points. Some are expert chefs; others have never held a knife. The standard BOPPPS model doesn't always give the right amount of help to the right person at the right time.
The Solution: The SOLO-BOPPPS Model
The researchers at Jining Medical University decided to upgrade the recipe by adding a special tool called SOLO scaffolding.
Think of SOLO (Structure of the Observed Learning Outcome) as a set of customized training wheels or a ladder that adjusts to the student's height.
- Level 1 (Unistructural): Just looking at one gear. (Simple questions: "What is this part called?")
- Level 2 (Multistructural): Looking at a few gears. (Questions: "List how these three parts work.")
- Level 3 (Relational): Seeing how the gears connect to make the machine run. (Questions: "How does part A affect part B?")
- Level 4 (Extended Abstract): Designing a new machine using these gears. (Complex questions: "How would you fix this if the machine broke in a new way?")
In this study, the teachers didn't just lecture. They handed out visual "scaffolds" (like fill-in-the-blank diagrams and step-by-step guides) that matched these levels. During the class, students used these guides to build their understanding piece by piece, rather than trying to swallow the whole puzzle at once.
What Happened in the Experiment?
The researchers tested this new method on 61 first-year pharmacy students. They split the semester into two halves:
- Phase 1 (The New Way): They taught using the SOLO-BOPPPS model with the custom scaffolds.
- Phase 2 (The Old Way): They taught the rest of the course using the traditional Lecture-Based method.
They also compared these students to a group from the previous year who only used the old lecture method.
The Results: A Clear Win
The study found that the new method worked like magic in three key areas:
They Were Actually Looking Up:
The researchers used a high-tech camera system to count how often students lifted their heads to look at the teacher (instead of staring at their laps or phones).- Old Way: Students looked up about 50% of the time.
- New Way: Students looked up 68% of the time.
- Analogy: It's the difference between a crowd of people nodding off during a speech versus a group leaning forward, eyes wide, trying to catch every word.
They Learned Better:
When it came time for the final exam, the scores for the chapters taught with the SOLO-BOPPPS method were significantly higher than the chapters taught the old way.- New Way Score: ~39 out of 50.
- Old Way Score: ~34 out of 50.
- The students who used the new method also scored higher than the entire group of students from the previous year who only used the old method.
They Felt More Confident:
When asked how they felt, the students gave the new method glowing reviews. They said it helped them focus, made the material easier to understand, and gave them a sense of achievement. Even the students who felt a little "pressure" or "tension" during the class reported feeling a huge sense of joy and accomplishment.- Analogy: It's like the difference between being thrown into the deep end of a pool and drowning, versus being given a life vest and a ladder to climb down step-by-step. The "pressure" of the challenge felt good because they knew they had the tools to handle it.
The Bottom Line
This study shows that by combining a structured lesson plan (BOPPPS) with a personalized set of learning guides (SOLO scaffolds), teachers can turn a confusing, overwhelming subject into a clear, manageable journey. It helped students pay attention, learn more, and feel good about themselves, proving that the right kind of support can help anyone climb the ladder of knowledge, regardless of where they started.
