Completion of a first-semester chemistry (Chem I) course lays the foundation for understanding second-semester chemistry (Chem II) topics. The purpose of this study is to evaluate the influence of basic arithmetic skills on students’ Chem II success in understanding mathematics-grounded concepts (e.g., solutions and aqueous reactions, kinetics, equilibrium, acids and bases, solubility and equilibria, thermodynamics, electrochemistry, and nuclear chemistry). Previous studies suggest a strong correlation between arithmetic preparation and performance in general chemistry courses, though few have focused on the second-semester course. In this investigation, researchers from six higher-education institutions in Texas, USA of different sizes and with student bodies of different diversities have collaborated to determine whether the Math-Up Skills Test (MUST) is able to reliably identify at-risk students from a population of n = 1599 at the beginning of a Chem II course.

算术自动化对第二学期普通化学课程学生成功的影响

完成第一学期化学（Chem I）课程为理解第二学期化学（Chem II）主题奠定了基础。这项研究的目的是评估基本算术技能对学生理解化学基础概念（例如，，溶液和水反应，动力学，平衡，酸和碱，溶解度和平衡，热力学，电化学和核化学）。先前的研究表明，普通化学课程的算术准备与成绩之间存在很强的相关性，尽管很少有人关注第二学期的课程。在这项调查中，来自美国得克萨斯州六个不同规模的高等教育机构的研究人员与不同多样性的学生团体进行了合作，以确定数学能力测试（MUST）是否能够可靠地识别来自高中生的高风险学生。Chem II课程开始时，n = 1599的人口。
