Errors Analysis of Grade VII SMPMTs Mathematics Textbooks on Material Ratios and Alternative Improvements

Abstract

The purpose of this study was to analyze errors in mathematics textbook class VII SMP/MTs on the ratio of material contained in chapter three of the book and provide alternative improvements. The results of this study can be used as material for consideration in improving textbooks. This is descriptive-analytic research, in which a problem is described and the results are analyzed to draw conclusions. The results of the study showed that there were still some errors in mathematics textbooks for class VII SMP/MTs on the material ratio. These errors include conceptual errors, computational errors, drawing errors, and writing errors. Each of these errors is then given an alternative fix that allows for further book development.
