Standard classroom tests tend to showcase what students know at that point in time and do not usually reflect real-life mathematics. They are not always accurate indicators of what students understand and how they understand it. I wanted to use an assessment tool that would allow students a better opportunity to exhibit mathematical growth in understanding and attitude over time. This tool should also give students the chance to show that they could communicate in a mathematical context, exhibit problem-solving techniques, and make mathematical connections to other subject areas. From these ideas and my review of the research on assessment, I decided to use portfolios as an assessment tool in one of my eighth-grade prealgebra classes.
