The purpose of this quasi-experimental non-equivalent pretest posttest control group research was to determine whether or not the use of a collaborative pH computer simulation has an impact on the knowledge, confidence, and conceptual understanding of fundamental pH concepts for undergraduate Chemistry II students. A purposeful sample of 59 Chemistry II undergraduate students were administered pre/post assessments and surveys. Results indicated higher pH knowledge, pH confidence, and pH conceptual understanding among those students who had completed the collaborative computer simulation modules (23 students/intervention group) instead of the alternative traditional classroom assignments (36 students/control group).

使用协作式计算机pH模拟来增加化学专业学生对pH的知识，信心和概念性理解

这项准实验性的非等价测试前测试后对照组研究的目的是确定使用协作式pH计算机模拟是否会影响化学专业II的学生对基本pH概念的知识，信心和概念理解。有目的地对59名化学II本科生进行了抽样，以进行评估前/评估后的调查。结果表明，在完成协作计算机模拟模块的学生（23名学生/干预组）而不是替代性的传统课堂作业（36名学生/对照组）中，这些学生具有更高的pH知识，pH信心和pH概念理解。
