Description

How should you organize your online course content? Based on cognitive information processing (CIP) research (Mayer, 2001 & 2005), it is recommended to break down information into smaller, more manageable pieces or “chunks.” The sizing of the chunks means that the effect on cognitive load will be reduced and it creates somewhat of a scaffold for the user to concentrate on performing rather than using the system (Moore, Dickson-Deane, & Liu, 2014; Van Merriënboer & Sweller, 2005).

Chunking operates on many levels. All of the following elements contribute to chunking and making text manageable: short sections, short paragraphs, short sentences, lists, tables, pictures, and examples. If the text seems dense to people, they may not even try to read it. Here are six keys to organizing logically within a page of content:

  • Break the text into manageable pieces or "chunking."
  • Put in many headings.
  • Write useful headings.
  • Make the headings into a table of contents.
  • If the information is sequential, put it in that order.
  • For non-sequential information, put what users need most first.

Dr. Camille Dickson-Deane from Montgomery County Community College

Figure 1: Use questions to reflect learner goals

Dr. Camille Dickson-Deane from Montgomery County Community College developed these guidelines for designing online activities using A Simple Knowledge (ASK) System (Thompson and Thompson, 1983) as a knowledge based system that allowed users who wish to create, test, modify, extend and make use of his own knowledge base:

  1. Select a topic to design. Any topic can be used to model this system. A topic that is ill-structured/complex can be best modeled using this method. Also, you as the instructor/designer should know the topic in its entirety.
  2. Create questions that will reflect your learner/performer’s goals. This requires a change of hats whereby you will have to think of the learning/performance objectives and also the level of learner who will be pursuing the said objective. The questions should incorporate the learner you anticipate will be using your design.
  3. Create sub-questions (if need be) which will reflect the parent questions. All the sub-questions should reflect the key areas where activity is required so that the parent question can be answers/achieved. A combine number of sub-questions should answer a parent question (see Figure 1)
  4. Identify key segments of information which will help answer the questions. The segments of information should direct the learner/performer to various locations where knowledge can be sourced. This information should be chunked so that there is no information overload thus using micro-learning strategies to manage the effective acquisition and processing of the information into knowledge and/or behaviors. These segments should also use media elements (video, audio, graphics, interactive elements, etc...) to assist with the dissemination of the material (see Figures 2).
