A comparison of strategic development for multiplication problem solving in low-, average-, and high-achieving students

The present study investigated the differences of strategy use between low-, average-, and high-achieving students when solving different multiplication problems. Nineteen high-, 48 average-, and 17 low-achieving students participated in this study. All participants were asked to complete three different multiplication tests and to explain how they solved these problems. Results suggested that low achievers used incorrect operation strategies more frequently, indicating a lack of conceptual understanding of multiplication. High-achieving students demonstrated greater flexibility in problem-solving and were more accurate in performing direct retrieval or math algorithm strategies. Results were discussed about improving low achievers’ use of advanced strategies, enhancing their flexibility in choosing strategies and improving students’ accuracy in using direct retrieval or math algorithms.

高校审计工作之我见

当前。我省高校经济责任审计职能弱化，究其原因，当然有多方面因素，但根本原因是法规、制度的修订与快速发展的市场经济不能同步。在实际操作中存在较多的灵活性和模糊性。加上单位领导认识上的片面性．没有重视审计队伍建设和人本管理，未能有效实施内部控制制度，导致审计监督职能弱化。腐败现象犹如猛兽、泛滥成灾。引起经济理论界及人大代表的提忧和深思。本文要有据高校审计工作的现状和问题，探寻内审工作面临困境和弊端的根源．构思出几点相应措施和对策。

Foam separation of chromium （VI） from aqueous solution

Removal of chromium (VI) dissolved in water by intermittent foam separation was implemented with cetyl trimethy-ammonium bromide as surfactant. The influence of various factors on removal efficiency was systematically studied. The removal efficiency has a maximum value near pH 4.0; thus, most experiments were carried out at pH 4.0. The orthogonal experiment was conducted to confirm the optimal operating parameters. The orthogonal experimental results show that when the liquid feed concentration is 10 mg/L, the pH value of feed solution is 4.00, air flow rates 0.9 L/min, surfactant dosage is 300 mg/L, the maximum removal efficiency of chromium (VI) reaches 97.80%, and condense multiple reaches 1 711. The kinetic test indicates that the foam separation of chromium is a first-order process. The equivalent rate constant calculated from the slope is 0.406 4, and the equivalent rate equation is obtained.
