Learning Objectives

This PowerPoint was made to teach primary school student mathematics. The learning goal of this PowerPoint is to understand how to calculate the volume of a rectangular prism.

Updates and Changes

There are not too many places to change because this topic and PowerPoint is very simple. Most changes I made is deleting redundant information in the pages. Instead of writing these texts in the pages, I choose to explain more with my voice now if I make this presentation again after understanding the Modality Principle. In page 3, the Redundancy Principle and the Coherence Principle are emphasized because I delete the explaination of why it is not a prism. The Redundancy Principle suggests that people learn better with narration and graphics than narration, graphics and text. There were too many words that can be overwhelming for a learner. Also, based on the Coherence Principle, simple text and simple visuals that relate to the topic are more effective for learning. In page 6, I add some bold to the text to highlight the important information which is the Signaling Principle.

Not change

Most of the pages remain the same as before. I do not change the order of these pages because it follows Merrill’s First Principles. Knowledge is activated, demonstrated and applied in order. The existing knowledge of shape/length/width/height/area is activated in the topic which is the Pre-Training Principle. The Image Principle, the Multimedia Principle and the Spatial Contiguity Principle are used a lot because I used a lot of images to explain the topic and make the volume visible instead of imaging it in the brain, and most text are next to the image to illustrate what I am try to say. The link in page 6 demonstrates the Segmenting Principle well, because learner can control the cube to understand how the cubes form a prism and how the volume is calculated step by step. For the general design of this PowerPoint, I keep the color same and balance the text and images in most pages. Also, I left a lot of negative space to make the PowerPoint succinct.
