Through observations and experience, it is interesting to see when students are motivated, engaged and interested in learning. In my own experience, depending on the type of learning and teaching, learning isn't always fun and engaging. I've also observed classrooms and got the opportunity to see what types of learning are more engaging for students.
From my observations, teaching and my own experience, I noticed that students enjoy visual representations, manipulative, acting/performance and especially technology related activities. I also, loved to learn when I could do hands on learning. For example, even in math contents, it is so much more interesting when the teacher talks about the content and have us work with cubes or shapes or computer game.
During my student teaching observation, I taught a math-area & perimeter lesson. I made sure every student had a zip lock full of cubes. These width, length and depth were all one inches long and they could be attached/detached to another cube. After introducing the lesson about perimeter and area, I had the students build their own model with the cubes. The students were given 2 minutes to build anything they wanted to. From there on, the students found the perimeter and area of the cubes and recorded on their white board.
I noticed that the students were having so much fun. Many students wanted to continue the lesson, because it was fun! Not only was the lesson engaging, but also students were able to have conceptual understanding of area and perimeter. I believe engaging and interactive learning helps students understand better and remember the concept more easily.
