Presenting solution strategies of fraction multiplication and division on mathematics instructional websites

Summary/Abstract: This study explored emphasized solution strategies taught by frequently found mathematics instructional websites, which teach students how to multiply and divide fractions. Based on the searching results of the well-known search engine Google,content analysis was conducted on 32 instructional websites containing fraction multiplication or division. For fractional division, this study found that 93.55% of instructional websites taught students invert-and-multiply to directly calculate the results by expressions, while 16.13% and 19.35% of websites taught students picture division and common denominator,respectively, mainly through graphical representation with text explaining the fractional operation process. Each solution strategy of fraction multiplication and division possesses different characteristics and advantages; therefore, teachers or instructional designers’ in future instructional web design or development should provide diverse solution strategies for students to learn and strengthen the solution process description.
