Reflection: Developing a Conceptual Understanding Part 1-The Structure of the Earth - Section 3: Explore


Guided Gallery Walk

I combined two different strategies, guided notes and a gallery walk to create a “guided gallery walk.”  In a typical gallery walk, students rotate through stations within the classroom analyzing and evaluating posted concepts. Each station or exhibit in a gallery walk displays a poster or chart of some kind presenting ideas, pictures, readings related to the lesson concepts. In my version, guided gallery, encourages students to take ownership of their task.  As they explore each chart, they are encouraged to work cooperatively with others promoting their use of speaking and listening skills.  

In my lesson, I prepared charts presenting information on the Layers of the Earth’s structure and displayed them around the room.  Then I created a matrix graphic organizer that outlined the intended notes and concepts I wanted the students to fill in about each layer of Earth's structure.  By providing students with this type of outline, my students were actively engaged during the reading assignment and recorded more accurate notes which they needed to apply it to later assignments:  constructing a scientific investigation and creating a model of the Earth’s layers. In addition, they were focused on recognizing the most important details for each layer. I found it gave them responsibility to be on task throughout the walk, yet be active participants as they moved from chart to chart and prevented them from sitting too long, losing interest, or attention.  I was able to monitor students understanding or misconception as I walked around and checked in with questions and how they synthesize the information displayed.  

Overall, throughout this lesson, students were very engaged. I noticed how attentive they were in filling in their data tables accurately. With only four layers of the Earth to gather information on, I ended up displaying multiple charts of each layer around the room. I told students if they completed one station, they could move on to another station.  Letting them move at their pace was beneficial because it allowed students who needed extra time to get it while others who were ready to move on could do so. This supported differentiation for students.
