Acetates

I use acetates to supplement the learning curve in my classes. I think they are invaluable to some lessons. I dont use them in every class, because they are not needed and in fact they would take from the lesson. For example, I was teaching a class on Archaeologists at work. Instead of acetates, I brought into class, archeological tools, such as, trowels, brushes, picks, skeleton sheets. From the start of teaching, I have been using single acetates. After the Ed tech Lesson I learned how to use different layered transparencies. I created the layered transparencies in class and they were brilliant, as the students saw the start of a feature to the whole development, explaining their geological processes at the same time, as I placed transparency on top of the next.

I created a layered transparency on the processes of coastal Erosion. My first layer was the headland and calm water. The second layer was an arrow of strong wind blowing against the headland, causing further weathering. The third layer included stronger waves, cracks in the headland and it included the terminology of coastal erosion, ie Hydraulic Action, Corrasion and Compression. The base layer included the process of Attrition and particles in the water, as stone hits against other stone to erode the headland, in this process known as Attrition. These layered acetates will be used in my class to promote the learning on Coastal Erosion. The acetates are visual guides to both students and teacher and the layers will facilitate the process of explaining the coastal erosion better.

Acetates as visual aids are the way forward.
