An investigation into the effect of diagrams on performance in ordinary grade physics questions

Abstract

This research attempts to examine the effect of the inclusion of diagrams in Ordinary Grade standard Physics test papers of the extended answer variety.CHAPTER 1 contains a general outline of the main factors in the test design, the sample, validity, the hypothesis itself and the type of statistical test to be used.CHAPTER 2 outlines a proposed hierarchy of diagram types, and goes on to consider in detail how the factors mentioned in Chapter 1 relate to the experiment.CHAPTER 3 details the results of the tests applied to the sample, and the result of the opinion test conducted in one of the schools.CHAPTER 4. contains conclusions and recommendations for further research into this subject area.
