| Operation solving mainly refers to correct operations according to algorithm and operational rule. Curriculum standard requires students to understand the rules and seek simple and reasonable computed path to solve problems. This article takes a survey about seventh-grade students’cognition of arithmetic solving and finds seventh-grade students’ cognition of arithmetic solving is on uneven levels and there is gap between their levels and the requesting of curriculum standard, so with the "seventy percent doing and eighty percent Commenting " learning activities expanded, it interposes student’ computing solution cognitive, makes students to analysis preliminary, learns how to choose the appropriate algorithm and computing to solve more flexible, rather than staying in the phase of imitation operational. That is to achieve the phase of connecting in computing solution cognition. |
