Avoid showing off your command of the English language by using such phrases as: ‘Elaborate on the fundamental ramifications of hylampherism’. Instead, ask (‘What happens when the lever is lifted?’) ? Attempt to reduce complex material and ideas to a simple, easy to understand form. The best way to do this is to start with something your students know about and build on that knowledge in small steps. ? If you are required to demonstrate something, make sure you can do it correctly before you show the students. ? Make sure all students can see even the smallest points of a demonstration; if necessary, gather them around you. ? If you are doing a simultaneous demonstration and explanation, break the demonstration down into small steps and explain each step thoroughly, giving reasons, examples and comparisons. USE VISUAL AIDS AND USE THEM EFFECTIVELY Reason: Approximately 75% of all learning comes through sight. Sources of ideas: ? graphic artists or personnel associated with the production of visual aids ? other instructors, who can often give spark to an idea ? commercial displays in newspapers, magazines, television and stores ? finally, your own imagination, which (if you give it full rein) is an excellent source of ideas for aids. Types of visual support: ? actual equipment ? mock-ups, charts, diagrams, pictures or models ? DVDs, films, videotape and cassette recordings ? sometimes, people. Guidelines: ? Plan the lesson first, and then select the type of visual support that helps students learn the material. DO NOT select a visual aid and then try to build a lesson around it. Just because the aid looks impressive, it does not mean it will fill the need, the need being to help your students learn the ‘must-know’ information. ? Plan to use a visual display of all major points that are covered during your lesson. Simple wording on the whiteboard is usually better than repeating the main points over and over again. |
