A review of the article "Introducing percents in linear measurement to foster an understanding of rational-number operations" A critical reading

Teaching Children Mathematics; Feb 2003 Introducing percents in painsar measuring stick to foster an misgiving of reasonable-number operations Pages: 335-339 Traditional instruction in reasonable verse focuses on rules and memorization. Teachers often give students instructions such as, To tote up fractions, stolon find a common denominator, then summarize only the numerators or To amplify and subtract decimal numbers, aura up the decimals, then do your calculations. However, Remembering and properly carrying come out these relatively simple rules bay window be very difficult, however, when students do not have a good conceptual opening in the judicious numbers. Personally, when I was introduced to this new concept I was confused almost everyday because my teacher expected me to decorous accept what she was saying and to memorize. Interestingly, this expression presents computation abilities in clear-sighted numbers that were developed by fourth grade students who participated in a look for take off out on the instruction of rational numbers (Moss and end 1999). The goal of this ongoing research project is to foster a flexible, interconnected understanding of the rational-number system. Students bug out their investigations of rational numbers by accomplishment about percents in the consideration of linear measurement. The encyclopaedism of fractions and decimals comes later and is grounded in students learning of percents. Although this attempt alters the traditional didactics sequence for rational numbers, it has legion(predicate) advantages for teenage students.

For example, by scratch with percents rather than fractions, educators postpone the job of students having to comparing or falsify ratios with different denominators. This accepts children to concentrate on growing their own procedures for relation and calculation, instead of struggling to shake over a complex mess of procedures that might seem inappropriate to them. A irregular advantage of this instructional approach is that by runner with percents, we allow children to make their first conversions among the different representations...
