Reflection: Developing a Conceptual Understanding Modeling the cell membrane - Section 2: Content Review

 

I am a visual learner so I tend to incorporate visuals into my instruction.  Even when students do not identify as visual learners, I find that most people can follow a lesson that uses images and visual resources to support the learning.

Osmotic movement is not a concept that is easily grasped by students.  Students often wil struggle with the concepts of hypertonic and hypotonic solutions and the movement of water.  When I teach highly conceptual topics like these, I find that I am better able to build understanding when I use visual images to support the teaching. By showing students pictures and explaining the images, I am able to effectively bridge the gap in the understanding for most students because "a picture is truly worth a thousand words". 

When using images, it is important to narrate or explain what is being depicted in the image.  I try not to assume that students will be able to analyze an image and tell me what is occurring.  Many times I will explain what is being shown, using the "think aloud" strategy so that they can observe how I analyze an image for understanding.  Other times, I will ask students to analyze an image and tell me what they think is being shown.  Either strategy is effective and I will continue to use visual images to enhance the instructional experience for my students.

Modeling the cell membrane

Unit 5: Unit 2- Cells
Lesson 15 of 30

Objective: Students will model the cell membrane using bubble solution and perform a close read in order to better understand the fluid mosaic properties of the cell membrane.

Big Idea: Having fun with bubbles can help us model the characteristics of the cell membrane.
